Jet Stream trotted as quickly through the lobby of his apartment building as he could without drawing attention, the brown paper bag he'd just obtained clutched tightly in his left hoof. He hoped the medicine within would be the salvation to all him and his daughter's problems, that it would finally spell the end to this crazy weekend...

Well…

At least he hoped it would take away some of the intensity of the interactions with his daughter. He wouldn't mind taking her lovingly into his comfortable bed for a romantic cuddle session. Jet Stream shook his head heavily... what was he just thinking? It wasn't just about the intensity, right? He had to rid himself of all of the physical attraction for his daughter... right?

Jet Stream was jolted out of his anxious musing as his doorpony, Zero Gustav, intercepted him on his way to the penthouse suite elevator. "Hello Sir! Just wanted to report that no one has gone up or down from your suite since we last spoke."

Jet Stream sighed, giving Zero a nod of thanks as he stepped into the elevator and hit the button for the penthouse suite's floor. At least one thing was going right so far today - he'd been so worried that Apogee might make an ill-advised escape during his trip to the pharmacy... and in her current state that would have been disastrous.

In no time at all he found himself unlocking his front door, stepping inside his condo and quietly closing the door behind him. He wondered absent-mindedly if Apogee was still in his bedroom, perhaps wrapping herself in his silk sheets...

His dirty, defiled silk sheets.

He felt himself stir as he imagined his teenage daughter playing with herself. Hoofing herself while she imagined him rutting her...

Again he shook his head in disbelief, what was wrong with him!? He obviously needed this medication more than he realized.

He trotted through the foyer, his nostrils already starting to dilate slightly as the scent of hormonal, teenage sex juices drifted through his masculine olfactory organ. It troubled him that he could recognize the taste of Apogee's heat, a cinnamon-sweet mixture that made him swallow eagerly, drinking her very essence out of the air itself. At least the estrus scent was nowhere near as thick as it had been this morning, when the pair had been overwhelmed by its effects.

His heart froze as he approached the living room, as Jet heard something he wasn't expecting.

Voices.

As in, more than one voice.

"...id Dad like it when when you played with his balls while you licked him or was it mo-" Jet Stream rounded the corner quickly, his eyes widening in surprise and shock: Apogee was speaking with Delta Vee.

His ex.

About playing with his testicles while licking him.

Delta Vee looked up, as she noticed Jet enter the room. She looked like her usual tired, sloppily put together self. She seemed to be completely nonplussed by Jet's sudden appearance, regardless of the rather private nature of the current topic of conversation. She raised a hoof nonchalantly in greeting.

"Hey."

Apogee turned around quickly, seeing her father for the first time. Her pupils shrunk as her eyes widened in shock. Jet Stream felt himself reacting the same way to the current scenario: just what had she told Delta!?

"WHAT." Jet Stream croaked out.

Delta Vee shrugged, before leaning back on his couch."Eh... I was jus-"

"D-delta..." Jet Stream began without solicitation, visibly shaking and sweating, "I-I j-just want to say that what happened was a total accident," Jet Stream kept babbling and spilling the beans, his entire life flashing before his eyes as he tried to explain away the previous day's events. He was completely missing the signals Apogee was trying to send him: her lips were pinched together and her head shaking vigorously in a desperate attempt to shut him up. "Y-you see, w-when I got home Apo-"

"OK DAD, CAN I TALK TO YOU FOR A SECOND!?" Apogee sprang off the couch, tackling her father in a half-hug half-bulldoze which she used as an excuse to push him into the 1st floor bathroom, closing the door behind them. Leaving behind a bemused but still tired Delta Vee alone on the couch in the living room.

"Huh, guess she really had to take a leak." Delta snarked aloud to herself, knowing that her kid was actually probably trying. In her usual way, to manage the interactions between her and Jet Stream to a smooth outcome.

Inside the bathroom, though, a very different discussion was taking place.

"W-what is she doing here? What did you tell her!?" Jet Stream asked keeping his voice as low as he could in his panicked state.

"I don't know! She just show-..." Apogee paused, looking down at her hoof.

She'd just stepped in something slimy. Picking her fore-hoof up, she tilted it in front of her face to see that she had stepped in some of her father's juices, left over from the pair's anal excursion the previous evening.

"Ewww..." Apogee whined petulantly, teenage filly that she was, before wiping her hoof on the nearby hand-towel.

Jet Stream realised what his daughter had stepped in, looked around to see... to smell the catastrophe that was the aftermath of just one of their fun activities and couldn't help but to slap his hoof to his forehead. "Celestia, I am so royally BUCKED!"

"N-no Dad," Apogee shushed him with her hoof. "I thought the same thing but turns out mom's got a burnt-out nose: she can't smell a thing!"

Jet Stream whispered to her through clenched teeth, his stress not assuaged at all by his daughter's hopeful explanation: "Then just what the hay were you two talking about out there?"

Apogee's head tilted in momentary confusion, so Jet Stream elucidated further. "Apogee… Why were you asking her about... p-playing with my... y'know... those!?" He stammered out, finding it awkward to speak with his teenage-filly about his testicular stimulation preferences.

"Oh!" Apogee clapped her hooves together, "Well... mom was just telling me about the first time you two slept together back at Coltumbia University... It was pretty cute." Apogee smiled at her dad.

"The first time we...?" He blushed, remembering that passionate night... that perfect night with Delta... One of the few nights before their pre-marital relationship became such a horrible mess of passion, booze, fights, and excess.

"Y-yeah." Apogee smiled, before becoming a little bashful. "I... I wanted to find out from her w-what you liked for when... we... uh..." Apogee trailed off as her whole face turned a deep crimson... A crimson only matched by the shade her father was currently sporting as he reacted to hearing his teenage filly admit that she was genuinely trying to find a way to improve her performance with him.

Their brief moment was interrupted by a knock on the door.

"Uh... You two OK in there?" Delta Vee's voice came through the door.

Apogee quickly burst out of the bathroom, with her father in tow. "Yes!" She squeaked, "Just had a bit of a bathroom emergency!"

Delta Vee arched an eyebrow, "And... what, you needed him to help wipe your butt?"

"Ahaha," Apogee forced a laugh, "Ew. Mom, don't be gross!"

Jet Stream sighed, and decided to bail out his daughter before she dug too deep a hole for the both of them. He placed his hoof in front of his daughter so he could easily step between her and Delta and take charge of the conversation.

"Apogee was trying to explain to me why her mother might be explaining to her teenage daughter everything about her father's preferred... uh... techniques."

Now it was Delta's turn to look a bit sheepish. She rubbed a hoof behind her messy, bedraggled mane. Was that not something a mom was supposed to share with her filly? Probably not... oops. Still it wasn't that big a deal, was it?

Delta tried to shrug it off, "Uh... whoops?"

"Setting THAT aside, why exactly are you here Delta?" Jet Stream asked, pointing a hoof at her.

"Eh. The kid kept one of my keys... As well as some..." She looked over at Apogee, who was blushing, before she decided to spare her teenage daughter from further embarrassment in front of her father, "...some, uh... stuff from my place that I need. I wanted to pick it up quickly. What's the big deal?" Delta asked, starting to shift forward on her hooves.

Jet Stream frowned and shook his head ever so slightly.

Delta Vee felt her eyebrows pinch together in anger, her tone becoming slightly more aggressive as she realized she was being interrogated by the very stallion who had dumped the filly on her at the beginning of the week in the first place. "Hey! You're the one who's always inviting me over so that I can spend more time with our daughter in a 'more wholesome environment'... as if my junkyard is just some trash heap."

Jet Stream felt his voice begin to rise as well. "It IS a trash heap! That is the literal definition of a junkyard! And I didn't mean you can just fly in the window like I know you must have done... Y'know a little fore-notice, coming up the elevator like a civilized pony!?"

KNOCK KNOCK

Delta scoffed, her jaw setting forward in anger. "Oh yeah, sure. I'll make sure next time to give a 'civilized' pony like you plenty of forewarning so that I don't interrupt one of your disgusting romps with some call-mare who lifts her tail for bits!"

KNOCK KNOCK

Jet Stream wasted no time before he barked back, "Better than somepony who should be trying to pull her life back together but goes down to dive bars instead and lifts her tail for booze! And I have the right to know before somepony just sh-" KNOCK KNOCK KNOCK "...and who the hay is THAT!?" Jet Stream shouted exasperated.

"Oh, that would be the pizza I ordered." Delta said neutrally, switching suddenly out of her building tone of anger and heading that way.

Jet Stream was so flummoxed that he could only stare at her in open mouthed shock. "What?"

"Eh... I got hungry flying over here, and my favorite pizza place is only a couple of blocks from here." Delta began to trot toward the door, calling over her shoulder when she realized that Jet was still standing still, shocked into immobility by her pure audacity. "What? I got enough for all of us... I'm not rude."

Apogee chirped happily and bounced after her mom, "Sweet! Did you get one with anchovies?" Apogee followed her mom, tail swishing happily... teenagers love pizza.

Jet Stream was left alone, as he realized that his ex would be staying for lunch. He slapped his hoof back to his face, not for the first time that day.

"Oh you've got to be buckin' KIDDING ME!"

The three pegasi were seated around the condominium's granite-topped kitchen island, a large pizza pie sitting between the three of them, steaming hot...

Delta had quickly grabbed the pies from the pimply-faced earth pony (who had been escorted by a rather concerned-looking door-pony) before looking back and nodding with her muzzle toward Jet Stream, indicating that Jet Stream would pay.

Grumbling, the stallion had quickly given the bits to the pizza-colt and given a curt nod to his doorman before slamming the door shut and heading to the kitchen. By the time he got there his daughter was prancing around the island happily, waiting for the pizza to be served out as his ex set the boxes on the island.

Jet Stream quickly cleared the island of the various cereal boxes and bowls... and a... dildo? He shook his head angrily, promptly tossing the object over to Delta, who clandestinely put it back into Apogee's bag.

Finally, now that everything was all settled down, Jet Stream doled out three plates and opened the two cardboard pizza boxes, before pulling up a stool. Delta on one side of the rectangular island, and Apogee seated next to her father on the other side.

Jet Stream glowered over the island at his ex, and couldn't help tweaking her. "...that little thing is a bit small for a mare like you, wouldn't you say?"

Delta rolled her eyes, "Don't flatter yourself... it's not the size of the jumbo jet, it's the skill of the pilot... and honestly I think you should never have gotten your pilot license in the first place."

Jet seethed, before snarking back, "Oh yeah? Well this pilot has had 1000's of hours of flight time since your last trip - unlike you!"

Delta smirked with her own dissatisfaction, "Hah! This mare has had PLENTY of frequent flier mi-"

"Can you guys stop?" Apogee interrupted, rolling her eyes, a bit annoyed at her parents' childish antics. "First of all... We've got pizza! Second of all, I know you're both arguing about sex. All you're doing is making me feel bad. Give it a rest already."

Jet Stream and Delta looked a bit shame-faced at their daughter's rebuke, and both quietly reached for a slice of pizza. There was a brief period of silence that hung over the trio, as they took their first bites of the delicious, cheesy pie. It didn't last.

"So," Delta began, unable to help herself. "I hear SpaceZed had a very good week in Canterlot. Too bad for your company, huh?"

"Mom..." Apogee warned, putting down one of her hooves on the counter top.

Jet Stream frowned, "Huh, I didn't realize that garbage dump managers followed aerospace news."

"Dad..." Apogee put her other hoof on the countertop... was she going to need to play referee again?

"Kid, you don't even know what we're talking about..." Delta rolled her eyes at the teenage filly's antics.

"What I know is that both of you are just trying to hurt one another's feelings with your words." She took a quick bit of her cheese and anchovy pizza. "But most of the time you just end up hurting mine..." She sighed.

Delta and Jet looked at one another across the island, a grimace of shame shared between the two of them before they both looked back down at their food, chastened.

"...It was a stupid decision." Delta mumbled.

"What was that?" Jet Stream asked, looking up.

"I said, it was a stupid decision by the crown, to pick SpaceZed, I mean." Delta said, before taking a bite of her pizza. "Those stupid SpaceZed rockets aren't using any new technology, except that they can land the initial stage automatically. Compared to EquestriAero's Spaceplane Single Stage to Orbit proposal it was far less ambitious and had far fewer upsides."

"I know!" Jet Stream groaned. "That stupid playboy Tesla just took gen 1 rocket technology, slapped some fancy automation and 'drone-ship' landing pads on it, and thinks that he's some sort of visionary. That plot-hole should have just stuck to his tech company."

"Pshh... totally." Delta agreed. "The main engine on that cruddy Gryphon X rocket they proposed is some kind of monopropellant peroxide fuel, with a low specific impulse factor and some archaic carbureted fuel turbopump! They might as well have tied the payload to a hot air balloon!"

"Are you kidding me? The hot air balloon... At least that would be novel." Jet Stream laughed. "Did you know what his projected bit cost per pound to orbit is?"

Delta leaned over, smirking. "No. Tell me."

"15,000 bits!"

"PFffttt.... HAHAHA you're kidding!" Delta began laughing. "That's about as bad as the old rockets they were using when we were still in college! Our space-plane would have been half of that cost, even on the mark I version pilot shots!"

Jet Stream grinned. "I know it would have... though even at EquestriAero we still had to figure out how to handle the high atmosphere transition to hypers-"

"hypersonic envelope insertion, I know." Delta finished for him. "And I remember telling you back at Coltumbia that materials technology would catch up, and we could use the inevitable atmospheric compression to sk-"

"...skip along the shockwave front, right! I actually saw a paper at last week's Canterlot space conference about variable inlet designs for a SCRAMjet engine, which we could use above 70,000 feet... Reminded me of that same paper you wrote in freshman year." Jet Stream was getting animated and a smile was growing across his face, matched by Delta Vee's as they reminisced about the details of their joint work, designing Equestria's first space plane.

Apogee had a dopey grin on her face as she listened to her two parents nerd out about various aerospace design concepts. She'd never seen the two of them like this, getting along. She could see the passion in their faces about the engineering. This was nice - the two ponies she loved more than anything in the world actually get along - sort of... at least, getting along when having a discussion on a narrow subject.

Apogee sighed.

Why couldn't they act this way all the time?

"...no no, you could work around that issue by using a thaumic battery - it's a cutting edge piece of unicorn tech... we didn't have it back in our school days. They're so useful it feels like we're cheating, but they're as heavy as Celestia after the annual cake festival... It does save our design from needing to have a unicorn on-board with a magical output capacity roughly equivalent to Starswirl the Bearded." Jet Stream chuckled.

Delta chuckled, "Heh - that's good. You can probably save some weight on the avionics if you can replace those horn heads with a pegasus commander: reaction times and flight instincts are so lacking in those magic snobs."

Getting tired of being left out of the conversation, Apogee put down her slice of pizza and spoke up. "Do you guys ever want to fly your own rockets? Or do you just want to design them?"

Both Jet Stream and Delta Vee seemed to suddenly remember that Apogee was still there before they both burst out laughing at her question. Jet Stream managed to recover first, clearing the tears from his eyes. "No hun. It takes brains to build these things..." He held his hoof out over the table.

"Not so much to fly them," Delta laughed, before reaching out and hoof-bumping Jet's outstretched hoof, completing the age-old Coltumbia rocket engineer's derisive insult of pilots.

Delta realized what she had done and quickly snatched her hoof back, frowning at Jet Stream before turning and addressing her daughter. "Heck, they oughta replace those hotshot astro-ponies with shaved monkeys or just send up empty rockets with instrumentation." Delta snarked, as she gesticulated with her hooves animatedly, Jet Stream nodding along in agreement with his ex's statement.

Apogee pouted, feeling a bit embarrassed, her cheeks puffing out in shame as her parents shared another laugh. "Well," the teenage mare straightened herself, pushing out her chest and ruffling her feathers tapping her chest with her hoof, "I would love to fly the spaceships you design. I think it's cool."

A moment passed, as Jet Stream and Delta Vee looked at one another then at their daughter. A smile of sincere pride crossed his lips as he looked fondly at his daughter - she'd just said she wanted to be an astronaut.

"Th-that would make me pretty proud, kid." Delta Vee smiled for once, as she thought about her overly-energetic daughter piloting, heck, maybe even commanding an EASA mission. Delta felt her heart warm and fill, and had to blink to prevent her eyes from getting watery.

"You'd have to improve your grades quite a bit, hun..." Jet Stream said, still smiling with pride. "But I think you'd make a great space-pilot."

Apogee could feel the love around the table. She'd never experienced anything like this before - two parents who loved her just looking at her with pride and fully believing in her. It was incredible. "I... I'd only ever fly to space in something you guys designed, though." She chuckled, before bashfully looking back at her pizza.

For a briefest of moments... all the arguing and pain of the past was forgotten.

For that idyllic moment, all was right with the world for this little misfit family of three, maybe... Just maybe... This little family would make it.

The moment passed by, slipping back into the cruel and ever-growing horizon of the past, as they fell back into a contented silence and each grabbed their second slice of pizza.

Apogee's second slice quickly went awry.

Maybe it was the feelings of love from her parents. Maybe it was the energy she'd gotten back from the food she'd just eaten. Maybe it was the sense of embarrassment from speaking so candidly with her parents about her feelings and dreams... Or maybe it was the fact that her father's semen had been sufficiently absorbed by her body that it sensed she needed a 'fill-up'.

Whatever the reason, Apogee's heat began to rear its ugly head, the unstoppable, irrepressible force building once again.

It started with her belly starting to feel a bit warm. She could tell right away it wasn't because of the piping hot pizza in her stomach as that perplexing warmth spread down to her nethers, forcing her to shift her little butt on her stool uncomfortably. The friction of her adjustment just made things worse, as she felt her heat's throbbing insistence begin to build in waves, each pump of her heart making her lower lips swell and her wings start to get achy and feel like they should be extended.

Jet Stream had noticed his daughter's dilemma rather quickly too...

Partway through his second slice of pizza he began to notice a scent that was overtaking even the fairly egregious smell of the anchovies, even though he had none on his slices (he was begrudgingly thankful that Delta had ordered a second pie with just cheese, he never could understand how his daughter and ex liked the taste of the disgusting fish topping).

No longer was the aroma of baked cheese and fish able to drown out the smell of aroused teenage filly pussy, and his nostrils immediately flared at the returning hint of musky cinnamon in the air, which he knew was coming out of his daughter's body.

He glanced over out of the corner of his eye to see that Apogee was unsurprisingly squirming in her seat, one of her hooves rubbing her lower abdomen, her teenage wings ever so slowly starting to extend from the middle of her back. Her face was already blushing red in exertion and her lips were parting ever so slightly as she gave out hot little hasps of breath.

Crap.

"Uh, excuse me for a second. " Jet Stream hopped up off of his stool, "I need to use the toilet... Apogee could you come with me for a moment?" He asked over his shoulder as he trotted toward the first-floor bathroom.

"Hmmng?" Apogee dreamily looked over to her father, woken out of her reverie. "Uh... Oh! Y-yea sure!" She hopped off her stool as well.

Jet Stream nervously prayed that Delta Vee didn't see the conspicuous and sticky strand of filly-juice that stretched between his daughter's plot and its spot on the stool, before it finally fell like a gossamer thread to the floor below.

He put a hoof around her shoulders and escorted her from the kitchen, leaving Delta Vee to her pizza.

Delta took another big bite, chewing and swallowing before muttering to herself. "What is it with those two, are they bathroom buddies or what...?" She grabbed another slice of pizza, "...is kid-parent mutual butt-wiping some parental bonding thing I don't know about?" She shrugged and took another big chomp... Most likely the two were once again going behind her back to discuss the latest faux-pas she'd unknowingly messed up...

She sighed, resting her hoof on her chin belatedly, why she'd even bothered to try this visit, she had no idea.

"D-dad," Apogee nuzzled her dad's neck as soon as the bathroom door was closed. "I-I think I'm... mnn..." the filly paused to rub her thighs together, her rapid breaths landing hotly on her father's nape.

Jet Stream swallowed deeply, his hooves stroking his daughter's back comfortingly, reassuringly.

"I know, hun..." he unconsciously let one of his hooves trail down to her flank, kneading the pert teenage muscle there. Apogee immediately moaned into his neck and tried to lean into the exploring hoof, her tail flagging up and swishing her musk all throughout the bathroom's constrained atmosphere.

Jet Stream pulled away his hoof from her flank quickly, fighting the urge to drive his mouth against his daughter's gasping muzzle and send his hoof to explore even further south.

"...I know hun. I know it's back. I can smell it on you."

"D-dad, c-can we..." Apogee mewled, her dewy eyes looking up at him. Begging him.

"L-later, hun. Your mom's here right now, remember?" Jet Stream wasn't even shocked at himself for promising to satisfy his teenage filly later, as if it was no big deal. "For now, I'm going to give you some medicine, it's going to make everything better, OK sweetheart?" He produced the brown paper bag that he'd left in the bathroom earlier.

"P-please Dad..." Apogee moaned, one of her hooves starting to reach down to her father's flank. Whether she was begging for the medicine or begging for his medicine was anypony's guess.

Jet Stream hurriedly looked at the bottle, trying to decipher the symbols to discern the proper dosing to give. But it was all for naught, he couldn't understand the strange glyphs of the Zebrican language...

Apogee laid a long, begging lick across his neck.

Crap! He was running out of time here! It wasn't a large bottle... perhaps a quarter dose for her? He uncorked the top.

"H-here hun, say ahh..."

Apogee looked up at him, her eyes half-lidded and dreamy with desire. She opened her cute little muzzle as wide as she could and said Anhhh, revealing her flat pink tongue and throat. Little strands of sticky saliva connected the roof of her mouth to her lips as she gasped heavily with hot pants.

Jet Stream paused for a moment as he imagined ramming his stallionhood down her throat and exploding in her - he shook his head... focus!

He poured a good dollop... about a quarter of the bottle onto his daughter's tongue, watching the pink liquid slide down the slick, withering muscle into her throat before he straightened and corked the bottle.

"N-now, swallow hun."

Apogee did as instructed, a faint glow from the activating magic visibly sliding down her slender throat and into her belly.

"Good job, hon... it'll get better soon, I promise." Jet Stream stroked her ruffled blue mane. "Now, let's head back out there before your mom gets suspicious, OK?"

"Hmmnnnggh..." Apogee mewled, her tail still seductively flicking about, high in the air, "O-okay, Dad."

He turned his daughter around, opening the door and directing her back toward the kitchen with a gentle push on her cute little butt. He felt something sticky, and looked down to see his hoof was wet with his daughter's slick nectar, a silvery strand connecting it to his departing daughter's plot... He followed the strands back to its original, immediately seeing a set of hot, teenage filly pussy lips, swollen and dripping under Apogee's flagging tail, winking invitingly, just for him.

"Sweet motherbuckin' Celestia." Jet Stream murmured to himself as he felt his stallionhood begin to spill from his sheath. He lifted his sticky hoof to his mouth, tasting the incredible sweetness of his daughter's pure arousal - giving in to his desire one last time before taking what he thought to be suppressant.

"I really hope that this stuff is as strong as that pharmacist said it was," Jet Stream tilted the bottle back into his own mouth, swallowing another quarter of the contents. "'Cuz I sure as hay need it."

He left the bathroom as well, hoping his awkward shuffle would hide his growing erection.

On the way back to the table, Jet Stream felt something strange shifting throughout his body.

The warmth from the potion he had just swallowed was branching out in all directions from his gut, racing out along each artery and vein to all of his extremities. It wasn't an unpleasant feeling... just... tingly... and powerful. It was slowly making him feel more and more uncomfortable, however... not exactly the satiating and suppressing effect he'd been hoping for.

He paused briefly to reach down with a forehoof to scratch his balls nervously as he left the living area. Something was wrong: most of those tingling sensations were starting to congregate in his nether regions. He could feel the potion’s effects as the sensations slid in and around his reproductive organs swelling and shifting him. The caress of the magic could be felt throughout the various glands and vessels in his abdomen, the tissue in and around his testicles, and, of course, his cock.

Celestia, could he ever feel it there!

The tingles had accumulated enough to feel like a burning warmth by the time that he rounded the corner into the kitchen. Thankfully, Delta Vee was looking the other way while concentrating on her latest slice of pizza, otherwise there would have been no way she could have missed the massive erection he was sporting.

Jet Stream took his seat next to his daughter, instantaneously being assaulted with her estrus's rich perfume. Poor Apogee seemed to be stewing in a cauldron of her own juices; a thousand yard stare was stuck on her face as she bit her lower lip.

It seemed both of them desperately needed this potion to kick in sooner than later.

And kick in it did.

Just as Jet Stream reached out to pick up a slice of pizza, he felt that burning warmth becoming more and more insistent. It took every ounce of his will-power not to reach under the table with one of his hooves to stroke his suddenly aching shaft... or better yet, to simply tackle the overpowering source of teenage pheromones sitting next to him and rut her into oblivion. But he staved off those animalistic desires as the burning throbs pulsed more and more powerfully. His fear continued to ratchet up as he felt his cock straining under the effects of whatever that potion was... was this some unforeseen side-effect? Something was definitely wrong... his cock was getting hotter and hotter and... colder?

Jet Stream suddenly felt a coolness against his cockhead and shivered for a moment before he realized that his flare was now pressing up against the bottom of the kitchen island... something it had never done before while sitting on these stools.. Even when he'd had the most raging morning wood hard-on of his life and sat down for coffee, it still would leave a small gap between the tip of his dick and the underside of the granite counter-top.

As discretely as he could possibly manage, Jet Stream leaned back to get a better angle and see just what was going on under the table... Then immediately squeaked in wide-eyed shock and straightened up bolt upright, stunned by just what he had seen.

"Hm, didya say something?" Delta asked, from the other side of the table.

"N-nothing!" Jet Stream peeped out, as he started sweating profusely.

What the buck was that!? He asked himself.

What he'd seen was shocking: his stallionhood... which he was intimately familiar with ever since he was a young colt... larger than he had ever seen it before, by no small margin. Thicker, longer, darker... it looked obscenely menacing, like it belonged to one of those Zebras in those ridiculous porn movies.

Where his cock had probably been 11 inches long and as wide around at its base as a filly’s fore-leg yesterday…

Now… now it was pushing 15 inches long, and the fat throbbing base was easily as wide, if not wider, than his hoof!

And it was drooling.

Jet Stream started to pick up on sensations other than the still-continuing throbs... and realized that he could feel the rivulets of pre-cum sliding down his now-longer shaft, trailing down to where his balls lay against the stool seat-top, making an absolute puddle in his pubic fur and lap... and still those hot, magically induced throbs weren't stopping!

He could feel his flare getting pressed more and more firmly into the cool granite underside of the island counter-top as he shaft continued to agonizingly stretch, slowly and inevitably. The pressure being applied to his swollen flare had reached a level that it was too uncomfortable to stand any further.

Then, just as he was about to reach down to adjust himself so his larger stallionhood would rest more comfortably along the underside of the table, instead of into the underside... it happened.

He started to cum.

A lot.

What the buck!? His mind shouted internally, even as it was flooded by orgasmic pleasure chemicals. He hadn't even touched himself... he'd never had a hoof-free orgasm before!

Jet Stream clenched the edge of the table and leaned forward, gritting his teeth as he involuntarily performed little bucking gyrations in his seat. Splatter after splatter of thick cum was shooting from his now-rigid flare as he tried desperately not to scream out loud from the incredible sensation of his ongoing massive ejaculation.

He could hear the sound of his prodigious amounts of seed spilling to the floor underneath the island. Thankfully it wasn't a 'floating-island type': there was a solid section of rich mahogany wood between him and the other side of the countertop. It there wasn't, he'd currently be hosing down Delta's legs with heavy ropes of thick, spurting cum.

Perhaps Delta couldn't hear well over the sounds of her chewing, because the splatter-pitter-patter sound of thick semen as it shot in heavy jets from his cock head before ricocheting off the underside of the table and either falling to the floor or painting the side of the mahogany pillar, seemed cacophonous to Jet Stream. He squinted his eyes shut... at this point there was nothing he could do: he was along for the ride... he grimaced while trying desperately not to moan aloud as his overwhelmingly intense and long-lasting orgasm continued...

Splatter. Splatter. Splatter.

Buck, he'd never come this much in his entire life - even when he was a teenage colt in high-school clopping to his posters of Wonderbolt mares!

Splatter. Splatter. Splatter.

It just wasn't stopping!

Splatter. Splatter. Splatter.

Apogee seemed to have taken notice of something going on under the counter-top and looked over at her father...

...

She too had had a rather rough return from the bathroom to the table. While in the cramped and musky bathroom, Apogee wanted nothing more than for her father to nip her neck, bend her over the sink, pound his stallionhood into her and give her the bucking she so desperately needed. Instead she had been saddened when he'd meekly turned her away with the dosage of medication.

As Apogee began her walk back toward the kitchen island counter-top, turning to exit the cramped bathroom, she'd felt the welcome press of her father's strong hoof against her butt... and her marehood. It made her heart skip a beat as she trotted through the living room.

It was about then that she began to feel the cooling effects of the potion. Or what she thought was the cooling effect of the potion... Starting in her belly and spreading outwards, each racing throb of her heart seemed to deliver the dancing, electric tingles to the far reaching extremities of her teenage body... but most especially her pulses seemed to be sending them to her aching, moist filly-hood.

At first it seemed like the tingles were helping, bringing a welcome change in sensation to Apogee's already engorged and burning, drooling lower lips... but very quickly the horny filly could tell that something wasn't working as intended.

A huge pressure seemed to be building up from the tingles, making everything down there swell and throb worse. Unlike ever before she could feel her little clitoris parting her dripping folds as it grew larger... In fact, by the time she reached her seat the throbbing love-bud was engorged large enough to ever so delicately brush the cold wooden top of the stool - causing a chain reaction of sensation that immediately made Apogee's powerful teen vaginal muscles clench and wink.

And what a wink it was.

Apogee felt racing shivers of electricity trail up and down her spine as her filly-hood spasmed agonizingly, shooting her already engorged clit in and out from its nesting spot in her hot folds and mashing the sex-button against the cool stool-top. Her little wings shot out to either side rigidly and she nearly dropped the slice of pizza she was holding as she felt herself flood the stool with a massive squirt of filly-cum. The torrent of transparent liquid sprayed out in gooey, sticky strands down to the floor below... and yet she just kept clenching, in and out, in and out... again and again as her body was wracked with the powerful convulsions that drove her to grind her hips into the stool.

Apogee's lust mounted with each wave, her breath starting to come in raspy little gasps; her hips were gyrating faster and faster and her vision was going fuzzy... Right when she was on the edge of an actual orgasm, the winking finally began to taper off... and as her breathing returned to normal she caught a pleasant smell in her cute little nose; she also noticed that her father seemed to be clenching the edge of the table in some distress.

Apogee's nostrils flared as she looked at her rugged, masculine dad.

Celestia she wanted him to just push her up onto the countertop and mount her roughly from behind... Did he even know how good he smelled right now?

Apogee writhed on her seat, feeling her bottom get absolutely soaked from the pool of juices she'd just deposited there. Celestia help her, she just wanted to bathe in the scent wafting up from under the island... that oaky, almondy, acorn-like bitterness... wait... she knew that smell. Was he... cumming?

He was!

Apogee squee'd quietly: the badly-desire essence her body was screaming for was right there!

With so much biological, animalistic imperative driving the little filly, she couldn't help herself: her left hoof (the one closest to her father) shot out under the table searching hungrily for its target. Apogee's eyebrows lifted in gleeful surprise as she felt the hot, heavy, pulse-throbbing stallion-shaft there, and it was already a gooey-creamy mess.

She was beginning to wrap her hoof around her father's shaft when she realized, to her surprise, that it seemed different than it had this morning... larger, thicker... hotter? Like, to a large extent! Almost a shocking extent. The unexpected additional attributes were so stunning that Apogee pulled her hoof back as if she'd been stung.

Still trying to process what she'd just felt, the teenage-filly lifted her sticky hoof back up above the edge of the table clandestinely, before getting a wicked idea. Using the facade of raising her slice of pizza back to her muzzle, she brought the hot, sticky goo on her hoof up as well - carrying the creamy semen to her mouth. Faking a small bite of pizza, she instead took a big lick of her father's warm foal-batter off her left hoof.

The explosion of taste was incredible - her body immediately demanded that she get more of this wondrous substance inside her, and inside her now! Apogee couldn't help but close her eyes and give out a long and satisfied moan as she felt her body tremble with delight from the creamy treat sliding down her throat.

"Mmmmmnnnn...."

Delta Vee looked across the table at her daughter with a smile, "Yeah, I hear ya kid. It's my favorite too... tastes good huh?"

Apogee nodded, her eyes still closed before as she finished her swallow with a breathy little exhortation, "Ahhh... y-yeah! I think it's my favorite too... it t-tastes incredible." Apogee dropped both her hooves to her belly, patting it with satisfaction, before slyly only returning one of her hooves to the counter-top.

Delta's ears perked up as Jet Stream suddenly let out a breath it looked like he had been holding for 2 minutes, before panting slightly with some sort of exertion. His eyes seemed to be spinning lazily in their sockets as he finally let his death grip of the table-edge go. The usually composed stallion shakily raised his hoof back toward the pizza, as he intended to grab another slice.

Delta looked at him with an arched eyebrow, "Uh... you OK there?"

Jet Stream managed to nod and tried wave her off, "U-uh... uh-hungh..." but as he picked up another slice of pizza, he squeaked aloud and his wings shot out to full extension. The pizza slice flopped messily to the countertop partway between his plate and the box. Apogee was staring out nonchalantly away from the table, only one hoof above the counter-top... but she had the most wickedly mischievous grin on her face.

Delta suspiciously look at the two ponies acting strangely opposite her... she was about to call them weirdos, before she realized that would be the pot calling the kettle black. So instead she simply shrugged and took another bite of her delicious anchovy pizza.

Under the island counter-top on the opposite side, lots of things were happening.

Things that were making Jet Stream's teeth grit in ecstasy.

...

Poor Jet Stream had just been through a roller-coaster of emotions and physical sensations. He'd almost lost all control when Apogee had gripped his mid-shaft as he was still in the throes of spurting... but thankfully the filly had withdrawn her hoof almost immediately. A few heavy, powerful spurts after that, he had finally felt his seemingly-never ending orgasm taper off. The muscles in his abdomen finally relaxed and his stallionhood ceased its endless barrage, which had lead to him breathing and shaking heavily as he reached for another slice of pizza.

The poor stallion had finally been able to release his hold on the counter-edge, and catch his breath, his head swimming with a dangerous mixture of pleasure and panic. Surely, after such an intense and prolonged climax like the one he'd just survived he had to be fully drained... right? His cock should be softening and retreating back into its sheath rather quickly... right?

Not even close.

Unbelievably, Jet Stream felt his rigid member continue to throb angrily. It may have stopped spurting, but it was still more than raring to go.

The one upside of his ejaculation was that the organ was now slick enough that it had slid out against the underside of the counter... which was a good thing, otherwise it would probably be cracking through the granite by now if it was still facing upward.

Jet Stream had then tried to cover up his discombobulated state by reaching forward to grab another slice of pizza.... Sure his forearm was shaky, and he was huffing like a marathon runner, but everything was going fine: the pizza was on its way back to his plate when he felt an unexpected hoof suddenly wrap itself only around his massive shaft, though with his expanded size, it could barely make it halfway around.

He had dropped the pizza, stifling a yelp: his wing shot out in arousal as he felt the hoof begin to stroke slowly upward, milking him from the base of his cock (now a tangled messy mop of gooey pubic fur) before starting to squee its way up his shaft.

Celestia it felt so good, Apogee's little hoof couldn't get halfway around the throbbing shaft, yet it still felt incredible as she punctuated her smooth upward stroke with little wiggles and squeezes. Apogee smiled across the table at her mother as the filly took an actual bite of her pizza from her less busy hoof.

"Wh-where did you get this from anyway, mom?" Under the table, the slick remainder from her father's climax lubricated her ongoing stroking, which went up his shaft... and up... and up...

Celestia... just how long was he?

Delta swallowed her bite, and gave a little smile. "It's called 'My Little Pizzeria', it's just down the street from here."

"Oh? How'd you find it?" Apogee asked absent-mindedly, her focus actually on her hoof as it finally found the edge of her father's flare. Buck, it was so swollen right now! She tenderly slid her delicate under-hoof over the ridge, massaging what she knew must be a painful, throbbing glans for her poor father.

Next to the grinning, naughty filly, Jet Stream bit down on his cheek, his eyes crossing in ecstasy. His daughter was giving his cockhead such an exquisite and gentle rubdown, bringing him tantalizingly closer and closer to another climax... he was so close now... Celestia she just had to-

Delta looked down at her pizza crust to pick it up, and Apogee seized on the window of opportunity. At lightning speed she brought her massaging hoof up to her mouth, sticking the whole thing almost comically into her muzzle so she could take her time lapping up her father's cream which she had gathered beneath the countertop.

Delta looked up, still nibbling on her crust. "Heh, hoof-lickin' good huh?" She joked, using a line from a popular commercial that was playing throughout Equis.

"Mmm hmmm..." Apogee agreed, as she swallowed the thick cum she'd just scooped into her mouth, shutting her eyes in pleasure. It was so fulfilling. Her wings fluttered in joy at the taste in her belly... but it wasn't enough. She needed more.

Apogee lifted her cloth napkin to her lips, patting them daintily and conspicuously... Then she dropped the piece of fabric so that it fell to the floor.

"Oops!" Apogee pushed her stool back, "I'll get it."

She ducked under the table, leaving her parents to stare at each other across the island, an awkward silence descending over the both of them.

Delta took another bite of her pizza. A frown appearing on her face, not because she was left alone with Jet Stream, but because she felt so inadequate, so awkward in these situations. She was so bad at regular family conversation stuff like this, all she'd been talking about for the past 5 minutes was the freaking pizza. Come on, Delta, think of something else to say... "S-so... how's your pizza?"

Dammit.

Jet Stream was making a strange face - one of his eyes was twitching and he had a big dopey grin that stretched from ear to ear. "Mmmm... it... it's r-really good." He sighed, letting his tongue hang lazily from his mouth, making Delta grin and look at him with a bemused glance... it was pretty good.

Under the island, Apogee had just finished giving her father's enlarged cock a full tongue bath. The moment she'd ducked under the island counter-top in search of her napkin she had hungrily attacked her father's larger-than-normal stallionhood, her tongue tracing up the hot, throbbing shaft and lapping off the thick creamy remaining juices from his massive eruption.

The longer, wider rod rubbed into her mane as she nuzzled her way down to the base of her father's penis, licking up the sticky mess that had accumulated there. She buried her nostrils into his musky, sweaty balls coating them in a layer of her saliva as she suckled and licked aggressively eager to absorb every last bit of his cum.

Breaking off her lascivious licking of her father's balls (which she could swear had gotten larger than this morning as well) with an audible little pop, Apogee said aloud so her mother could hear: "D-dad, my napkin is stuck under your stool, I'm having trouble getting it." Before she immediately nuzzled his dick, grinding her face against the huge fleshy-rod as she dragged her tongue up its impressive length once again.

Jet Stream smiled goofily across at Delta as he answered his naughty little filly, "Mmm... you'll just have to try a little harder to get it, hun." Delta just rolled her eyes, perplexed at Jet Stream's strange behavior before she took another bite of pizza - she felt awkward, out-of-place... but she really had no idea how a family meal was supposed to go.

Apogee felt her father squeezing the muscles suspending his heavy stallionhood, making it twitch and bounce against her face - she had finally finished licking the entire pole clean of its coating of daddy batter.

Celestia, she could feel her body starting to react already, demanding even more of her father's sauce, but there was no more to be had on the jet-black skin of his shaft, or in the sweaty musky fur of his pubic region.

She was giving serious thought to lapping up the large pool of cum that had splattered and run down the island underside. Just before she bent down to do just that a better idea came to her.

Why not get some fresh batter?

She moved her muzzle quickly up her father's longer shaft, her tongue tracing up and under the flare to caress his aching ridge of turgid flesh. She felt him begin to twitch and jump under her attention, so she placed her other hoof on his shaft keeping him steady as she leaned in, booping the end of his cock against her cute little nose, before opening her mouth and suckling the drooling cock-slit.

"Hunnngggh....!" Jet Stream squeaked, as he felt his daughter's soft lips form a seal around his sensitive slit. "...hmmmrghh... ah-hem... sorry, had something stuck in my throat there." Jet made a conciliatory excuse to his ex.

Delta looked at him with a deadpan glance. "Make sure to chew properly." Delta felt like face-hoofing herself. 'Make sure to chew properly?' Celestia she felt like such an awkward idiot.

Apogee had begun to ever so slightly suckle, like a hungry foal at her mother's teat, sucking the sweet cum that she desired so badly out of her father's urethral tube. The remainder from Jet Stream's massive orgasm began to be drawn out like a thick milkshake being pulled through a straw. The delicious creamy fluid dribbled out in small squirts into the teenage-filly’s little mouth, falling onto her lashing pink tongue which raced against the underside of his glans.

Jet felt his balls beginning to throb and ache again, the fluid within boiling and building for another massive release.

He almost couldn't believe it. How could he be ready to cum again? This soon after the recent massive explosion he was surprised he had any fluid left in him at all!

The inevitable climax continued to approach, his horny little filly continued stroking her father's larger, longer, more aggressive shaft with both of her hooves while suckling his semen from his drooling cock-slit. Jet Stream felt his hips beginning to buck again... he felt himself trotting close to the cliff-edge of orgasm... Just a little... more... he felt his flare begin to stiffen up again and the powerful muscles in his abdomen start to clench...

"Apogee... kid? You doin' OK?" Delta asked, realizing that she hadn't seen her daughter for almost a minute, not since she had ducked under the counter-top in search of her napkin.

Apogee broke her mouth's seal with Jet's penis with a slurp, sucking up a thick strand of cum-juice right out of his swollen slit like it was some obscene noodle of liquid spaghetti, before unhappily popping her head up above the edge of the counter, back into view of her mom.

"Got it!" Apogee held the napkin up above her head in triumph. "Stupid thing was stuck - didn't want to give up and just give me what I wanted." Apogee used the napkin to again daintily wipe her muzzle, this time actually wiping off some unspeakable juices before they could be noticed by her mother.

"Uh... OK?" Delta said, unsure of just what her daughter was going on about this time. "Aren't you going to eat any more of your food?" Delta motioned toward the pizza still sitting in Apogee's plate.

"Nah... I think I'm good for pizza."

"Feeling full?" Jet Stream asked.

Apogee turned her head to look at her father with a coy grin. Her eyes danced with mischief. "Nah, I definitely don't feel full. Just don't feel like eating right now."

Jet Stream grinned back at her, wiggling his eyebrows slightly, before looking over to Delta. "Sooo... what's your plan for the rest of the day? Need me to call you a taxi-carriage?"

Delta cleaned her hooves with her own napkin, before putting it down on her empty plate. "Hmm, nah that's OK... but... I was hoping to get a little tour of the place before I go."

Jet Stream's grinning face fell. "What? Why?? You're usually the last pony who wants to put up with niceties like house tours and you definitely never usually want to spend any more time near me than you have to."

Apogee kicked her father in the shin under the counter-top, shooting him a glare. "Dad!"

Delta got a smirk of mischief of her own, one that made Jet Stream realize just how eerily she resembled her daughter.

"That's true," the cyan-furred pegasus began, "but I am actually a bit interested in how your rich, fat ass gets to live it up - it is the life I was supposed to have, after all."

As Jet made ready to reply with some snide remark about Delta's being the one with too much junk in the trunk, she cut him off, her grin was now a beaming smile. "Besides - usually you're trying to get me to stick around: so I take off. Now that you're trying to get rid of me, I figure I'll stick around for a bit... just to piss you off."

Jet Stream's face was turning red with anger. He wanted Delta gone ASAP. The longer she was here the more likely that everything would get revealed, they were already taking insane risks... even more importantly though, the longer she was here the longer it would be before he could pull Apogee down and pound her teenage pussy into happy oblivion. He snorted out at the thought of her tight filly-hood wrapped around him... all delayed by this bratty mare.

Jet Stream puffed up his chest, slamming one of his hooves down. "Now see here, why don't you ju-"

"Of course, mom!" Apogee had sprung off her stool and was dancing on her hoof-tips in excitement. "Let me give you the tour, we'll start in the living room!" She began to trot around the the island.

Great, Jet Stream thought, slinking down on his stool and letting his chin rest on his hooves, glowering as Delta shot him a shit-eating victory grin. Just great... what was that filly thinking??

As Apogee walked behind him, once she was out of her mother’s sight she groped his flank with her right hoof, followed by a playful tail flick against his own tail, their strands intertwining briefly as her tail bun brushed against his flank seductively.

By Celestia. Jet Stream gulped. She wasn't thinking. Not with her head at least.

Apogee bounced ahead happily, turning to beckon her mom to come with her as the filly chatted happily to no-one in particular.

"So Dad moved to this new place two years ago. Before then we lived in the building just over there." She pointed with her hoof through the floor to ceiling plate glass windows, "It wasn't nearly as nice as this place... but it did have a pool."

Delta grimaced and nodded, as the pair trotted into the living room. "A pool, huh? I've got one of those."

Apogee chuckled back, "Aw c'mon mom, that blast crater behind the junkyard doesn't count." Apogee directed her mom into the wide and spacious living area, which had ceilings that stretched all the way up to the top of the second story, leaving a wide open-air area perfect for pegasi.

Watching from the kitchen, Jet Stream chewed his lip and waited for an opportune moment to spring from his stool... now! He sprinted out of the kitchen, and propped himself against the back of the faux-leather couch... leaning in such a way that his throbbing erection was pressed against the fabric of the couch-back, invisible to the two mares in front of him.

Delta looked over at him with an arched eyebrow, as she curiously considered his strange posture. "I see you've got one of those fancy big-screen TVs." She glowered as the old flames of betrayal began to smolder up from inside her, "I've only got some shitty, piece of crap 15 incher."

Jet Stream looked past his ex's angry face, nervously watching his daughter adopt a wicked grin as she bent over seductively on the coffee table, her tail flicking back and forth. "Oh, Dad's got a 15-incher too I bet," she wiggled her eyebrows for her father's benefit, "I bet he probably brings it out in the bedroom at night." Apogee covered her muzzle as she chuckled at her father's panicky discomfort.

Delta continued staring down Jet Stream, who was now sweating nervously. "I doubt that... wouldn't be surprised if he has another big fancy TV up there... Seriously, this buckin' monster probably costs more than I make in a year... and you're enjoying all of this offa my hard-work... which you continue to take credit for."

Jet Stream rolled his eyes, he really didn't want to get into this argument right now. "...if it makes you feel any better, about the only thing that plays on this TV is Apogee's potato ponies... I never have time to watch anything."

He watched his filly in question pick up the remote control for the TV gingerly, bringing it up to her muzzle. What was she doing?

Delta continued looking at him incredulously. "Seriously? You never watch the hoofball games? The Las Pegasus Platinum Knights are going to the playoffs this year."

Jet Stream stammered. "Uhh..."

His attention had been drawn to Apogee, currently seductively licking the remote control, all while keeping her eyes on him... Doling out long, aggressive licks that started at the base of the remote and traced lavisciously up to the tip. Then she paused there for a moment, giving little flicking licks to the top of the remote with the end of her tongue... All just behind her oblivious mother.

"'Uhh...' what??" Delta grumbled, "Seriously, I bet the picture quality is great. I, on the other hand, can barely tell the difference between the ball and the ground on my POS TV."

Jet Stream swallowed heavily, watching Apogee start fellating the remote, pumping it in and out of her muzzle with sloppy strands of drool trailing out of her mouth.

"Uh... y-you're always welcome to stop by to watch the game, y'know... I'm sure Apogee would love it... if you... dropped by."

Jet stream barely managed to squeak that last word out, as Apogee removed the remote from her mouth... then brought it down to her rear end. She paused, shot her Dad a grin, looked Jet directly in the eyes and silently mouthed out: 'Love you Dad'... before plunging her hoof forward. The filly's eyes shut in bliss and her head leaned back as she bit her lip in passionate ecstasy.

Jet Stream couldn't see for sure where she'd just inserted his TV's remote control... but he had a pretty good guess... His wings involuntarily shot out to either side of him and resisted his efforts to awkwardly fold them back in.

Delta paused, seeing his wings shoot out, mistaking Jet's reaction for fear.

Delta's face softened slightly, changing from angry and belligerent to a mere scowl. "S-sorry... didn't mean to scare you... it's just that it's all such a load of bullshit." She sighed, rubbing her face with her hoof, trying to calm herself. "...but I don't think I'd come over for any hoofball matches... you've got no booze in the fridge. What's the point of hoofball without a cold one?"

Delta suddenly wheeled on Apogee who quickly straightened up and brought all her hooves to their normal, standing position. Her face scrunched and red with shock as she did her utmost not to reveal that she had stuffed herself with a plastic remote.

"Sorry, kid... maybe I'd come if your dad sprung for the cider."

Apogee just nodded nervously, trying to avoid her mother's gaze, as if she were keeping something in.

Delta tilted her head in curiosity, "Hello? Earth to kid? Something you want to let out?"

Jet Stream quickly spoke up, "Upstairs!"

Delta turned back around at Jet's outburst, giving Apogee the moment she needed to reach back and extract the remote control... Jet Stream didn't miss the squirt of filly-juice as she pulled the object from wherever it had just been and put it back, sticky and juicy, onto the coffee table.

"Let's take this tour upstairs!" Jet smiled nervously, still pressing his unrelenting erection against the back of the sofa.

Apogee hopped forward, took her mom by the shoulders and began to lead her up the modern-style stairs, with Jet Stream following closely behind. He could barely hear Apogee chattering on about some of the pictures that they'd hung on the wall next to the stairs - from various events in the young filly's life...

He was too busy looking at the two beautiful mare butts in front of him.

On the left was his daughter's cute little rump, her tight ponut nestled under the tail-bun, all perched over a heavily swollen and dripping set of filly lips. Her clitoris was fully exposed in a constant state of extension, even though she wasn't currently winking, and a constant stream of her filly-juice ran over it and down her plump vulva, forming sticky trails that ran down her inner thighs.

To her right was a more mature and rounder pair of flanks for Jet to ogle. Delta's rich blue-green tail hung in the way, blocking what would otherwise be a clear view, but as it swished back and forth he was afforded many opportunities to drink in his ex's plot... She still had that ever so plump ponut that he had loved to play with in college, a lovely round ring of muscle that she had always hated when he'd insisted on having some butt-fun... before she would eventually roll around and finally end up being the one begging for more anal stimulation... Just under that were Delta's lovely mare-lips. They weren't swollen or dripping like her daughter's currently were, but damn if they weren't just as inviting... and just under that, on Delta Vee's belly, he could see the swell of a pair of well-sized teats, looking none-the-worse for wear despite Delta's middle age...

Celestia he'd love to motor boat those teats... wait... what!? What was he thinking?

He sighed, rubbing his temples... the question was more probably: what was he thinking with?? It definitely wasn't his upper head.

Still, he just had to lean forward a bit, to get a little more of that incredible estrus aroma into his nostrils. He took another step up the stairs toward the two mares, who had just paused on their ascent to look at yet another framed photograph. So close to the origin now... He was mere inches away from Apogee's soft, drooling lips... Could he really stop here? He opened his mouth and leaned closer.

Apogee abruptly took another couple of steps up the stairs, to point out something specific in the photo to her grumpy mother. Jet Stream fumed in annoyance for a moment, before his brain reset, selecting a new target... it was no big deal... there was another perfectly good target, right... in front... of him...

"Huh!?" Delta jumped, her tail tucking between her legs as she whirled around, "W-what the hay!?"

Jet Stream's eyes were wide in shock and concern... what had he just done!?

"S-sorry!" He squeaked immediately, "I wasn't watching where I was trotting and just... uh..."

Delta rubbed her butt with her hoof, glaring at Jet Stream with a furious blush across her features. But Jet had no trouble seeing the genuine fury lit up in her eyes as she poked him in the chest angrily with her hoof. "I know plot-kissing comes natural to a sycophant like you, but watch where you're walking you asshole." With that she whirled around, keeping her tail tucked between her flanks now, and continued walking up the stairs to catch back up with her daughter.

Apogee shot him a sympathetic glance over her shoulder as she walked ahead of her mom, the naughty grin still stuck on her face.

Jet Stream sighed, before licking his lips.

...Still tasted like sweet grapes even after all these years.

Delta had quickly turned down the offer to see the master bedroom, saying she'd just seen it earlier that morning.

In actuality, she had no interest in seeing where her ex culminated his conquests. There was a deep part of her that hated that he was still socially active, still able to bed beautiful mares with abandon, while she was stuck with the dregs of the local bar scene.

So instead they'd take a left down the hallway to Apogee's room.

Thankfully, for Jet... the trip into Apogee's room had been completely taken up with the bouncy little mare showing off every poster, trophy and memento to her beloved mom, affording her no opportunity to perform yet another risky cock-tease of some type... until they were leaving the room that is.

Apogee had held open the door to let her parents out first, playing the part of the well-mannered filly. First Delta had trotted out to the 2nd floor landing, with no incident. Then, as Jet had walked past his daughter, she'd reached out with her nearest wing, and ducked under his barrel quickly, clandestinely stroking one of her primaries from the tip of his shaft down to its base, making him shiver along his entire barrel.

She'd smirked happily to herself with an outstretched tongue as a small squirt of pre-cum had drooled to the floor, leaving a sticky trail from her bedroom door to the final stop on their grand inspection...

The last room on the little tour: Jet's library and ensuite study.

The trio trotted into the new room, the style markedly different from the modern aesthetics of the rest of Jet's condo: rich oaks and thick carpets signaled that this was a room for serious study.

Delta whistled to herself as she walked past the library bookshelves, inspecting the various tomes that were ensconced there, before a certain set caught her eye.

"...A-are those first edition VonPons?" Delta rushed over to the beautiful, ornate books, almost drooling as she looked over the intricately bound set of engineering texts. "...Nice... gotta say... wish that I had those... all I've got are crappy-printouts of the important bits of his work."

Jet winced at the venom he heard in her voice and chose his words carefully; he knew that Warner VonPon was Delta's hero and he didn't want to set the surly pegasus off into yet another tirade if he could help it. "Y-yes... I've tried to take good care of them, he was an incredible scientist."

Delta harrumphed, a little disappointed that Jet hadn't risen to take her bait. Ignoring his meek statement, she pushed forward through the set of french-doors separating the small library from Jet's personal study and office. "And what's in here, I wonder?"

Jet hopped toward Delta, getting ready to cut her off, to intercept her and tell the nosey mare that his office was off-limits... when he got a facefull of blue-tailed, teenage flank for his trouble...

Apogee had used her mother's distraction as an opportunity to take flight into a low-hover... before skillfully backing-up into Jet's face to deliver a playful buttcheck.

Delta entered the smallish study, leaving the french doors open behind her as she heard a grumbling and giggling clatter as Apogee pulled some kind of mischief on her Dad... Always up to something, that filly.

Delta ceased her musing as she took stock of her surroundings.

Her eyes opened in slight surprise as she noticed that the walls and floors were covered in papers. Design documents, corporate memoranda, various financial and engineering reports... This was the office of an exceedingly busy and brilliant stallion.

'Huh' Delta grumped to herself, 'seems like he actually does some work, after all.'

She pulled Jet's heavy office chair away from the richly styled oak desk, hopping up on it without even thinking to ask permission and pulling herself up to her ex's work table. Again, not hesitating for even a moment to consider that she might be viewing some very private materials, Delta snooped with glee... Immediately catching her eye, resting on the center of his blotter, seeming as if it hadn't been moved in a long time... was a very familiar set of design blueprints for their spaceplane, and next to it, comprised of fading, yellowed paper: a thick-bound document with a very familiar title...

Jet let out a muffled, "No!" Right into his daughter's musky plot just as Delta walked into his office.

The little yelp was completely blocked off by his daughter's sweet flanks, who quickly flittered away from his flustered, flabbergasted face, as she tittered with little chirping giggles, having just pranked her dad.

He looked up with annoyance at the floating little teenage-filly who had been in his head all morning, and who had now just prevented him from stopping his ex from potentially getting access to his private journal. He scowled at her, getting ready to scold her.

But Apogee was just looking at him with her stuck-out tongue, her hips waving back and forth in his face sultrily as she gave him yet another naughty smile.

Jet had had enough.

This little filly had been teasing him all morning... all day... all weekend! Because of her, his cock was aching and drooling, leaving spatters of pre-cum all along the wooden floor throughout his house and dribbling a set of damp splotches on his library carpet... all because he was stuck staring at that sexy, little rear... and had then had gotten caught up in her damn rhythm, had been unable to break away from her playful and risky behaviours - that filly... she'd been in total control all along... but not anymore.

Jet reached up and grabbed his daughter by her athletic flanks, pulling her down by her butt, slamming her forcefully against the chest high library table in the center of the room, making the books on the table jump.

"Ooph... D-dad?" Apogee whispered, the wind partially knocked from her lungs... but Jet wasn't going to wait. He pushed her onto the table, grabbing her thighs forcefully and spreading them... then dove his drooling muzzle deep into her hot, steamy, teenage filly-snatch.

Apogee's wings spread painfully wide with arousal and shock as she gripped the table's edges with her forehooves, trying to steady herself. Wasting no time, her father's tongue drew itself lazily along her swollen, juicy, lips... then jumped up, running roughly over her little, engorged clit... before tracing the inner folds of her slit until the muscular, lashing tongue reached the top of her snatch - running up over the junction and going on to trace around her quivering tail-hole and over her sweaty dock.

Apogee's little love-bud winked happily as her Dad brought himself back down for another pass, this time spending more attention on her little nub of flesh, his tongue wrapping around it, caressing it, wrapping it with his fleshy muscular pink blanket, before leaning in with little kisses to suckle and blow on his daughter's sensitive love-button.

She began to squirm, her hooves sliding on the polished wooden table top as her body shook with the pleasure of her father's lavish oral attention. She squeaked lightly with each lick and suckle, her body twisting and grinding against itself internally, her hot swollen glands releasing copious amounts of fluid that spilled over her father's muzzle, begging him to continue... and all while her mother was just in the other room!

Apogee shuddered in fear and pleasure as she remembered the risk she was taking.

Thinking quickly, she reached lazily for one of the books on the table, bringing it to her mouth and biting down, hard...

Just in time too. As she clenched her teeth in lustful agony, a wave of feeling rushed through her from down below, a building warmth stemming out of the hot furnace of her nethers which exploded upward, cascading through her body… eventually becoming a stifled groan in her throat, making her bite down even harder on her book, drool pouring from her mouth.

The drool pouring from her mouth had nothing on the spurting volume of juice shooting from her filly-hood though. Jet had to pull back as squirt after squirt was sprayed at him, each blast coinciding with a muscular, winking convulsion as Apogee's rear humped vainly against the library table top. The filly was pouring magically enhanced estrus juices everywhere, soaking her father's face and splashing down to the library carpet below.

Jet stepped back, admiring his teenage daughter’s cute rear as she struggled to catch her breath. Apogee's mouth was still clenched down on the library book in her teeth, leaving a solid bite-mark there. The filly continued to squirm and wiggle from the aftershocks of her latest climax, her eyes rolling lazily, awash in a sea of pleasant dopamine swamping her neurological system.

"So I see you kept our thesis documents kicking around... must be fun to gloat to yourself about how bad you screwed me over!" Delta's voice carried over from the other room… she seemed to be pre-occupied entirely, reviewing the documents he'd left in the open in his office. Still, how long could all those design diagrams and technical texts keep her attention?

This shocking reminder of proximate danger should have been more than enough to kick Jet out of this lust-filled fugue he seemed to be trapped in... but... with all the environmental variables… all the atmospheric turbulence of the ZESPER… the estrus, the teasing... nothing would stop him now.

"N-n... NO!" He groaned, his mind replying on total autopilot as he positioned his rigid stallionhood up against his teenage filly's flanks.

His thick sausage was wedged between her tight ass-cheeks, the thicker than normal flesh squeezed by his daughter's tensing and twitching muscles as Jet slid himself up and down… his shaft trapped in her soaking, steaming plot. He could feel the underside of his cock being soaked in the sticky filly-juice as he slid up between her buns, his sensitive and engorged flare running along her sticky honey-pot and then over her tail-hole, before finally sliding up against her dock and into her tail hairs, as his thick hilt bumped against the bottom of her flank-cheeks… his significant length placing his medial ridge resting against her red-hot ponut.

"MMpph.... D-Daaa-hnngrk" Apogee started to moan out as her larger father hot-dogged his pipe against her plot, the force pressing her against the table, before he reached forward and covered her mouth with his hoof, muffling her groans.

"Ah-ah-ah... can't have your mom getting suspicious..." Jet whispered into Apogee's ear as he continued sliding his long, girthy stallionhood through her slick valley, a copious dollop of liquid, transparent pre-cum spurting from his flare through his daughter's tail hairs and onto her lower back with each of his thrusts forward.

He nipped at her cute, twitching ear. "At least, not before I've pounded your little filly-hood silly."

Still covering his daughter's muzzle with his hoof, Jet Stream re-positioned his rear hooves He needed to take a sizable step back and adjust his hips to bring his ZESPER-enhanced cock on target.

"Hmnnggh hahee..." He heard through his hoof, his daughter's tongue tickling his frog as she moaned out… the feeling of her father's fat flare dragging across her tail-hole and aligning itself with her winking, open sex igniting her passions further.

Jet Stream began to push forward... his daughter's teenage filly-hood was doing its best to accommodate his massive knob of a cock head… but ultimately… utterly failing: the soaked slick lips could only part painfully slowly. With his larger size, they were unable to simply permit him to glide into her depths easily.

The pressure Jet was increasingly applying finally pushed Apogee's cute teenage rear against the table-top, pinning her pussy between his hoof sized cockhead and the unyielding wood of the table... pressing harder and harder.

"Hunnggh... dahee plees… mmng..." Apogee mumbled through her father's restraining hoof, as her filly-hood strained to part itself wider and let Jet enter her twisting, volcanic interior.

Jet began short, violent thrusts with his hips, forcing his cock bit by bit into his daughter, stuffing her teenage pussy. His impatience was finally getting the better of him as he felt his daughter’s breath, coming hot and heavy against his groan-muffling hoof, as she grunted with resistance against the exertion of his pushes.

"Damn... since when were you so... tight!?" Jet growled, taking his free hoof and grasping his daughter's dock... yanking it up and using it like a pommel to leverage himself into her unyielding teenage-fillyhood with as much force as he could muster...

Then it happened.

Agonizingly slowly… his daughter's tight, strained, swollen lips parted around the top of his engorged mushroom... barely making it around his knobby, rigid, flare's ridge. Jet felt his daughter stiffen up just at the moment her filly-hood finally yielded… her back tensing and bowing as a nervous spasm wracked her, her wings flicking out and trembling... her dad was huge.

Jet felt his daughter’s clenching filly-hood tensing and relaxing around his fat, invading, organ… the spasms sending incredible pleasure sensations through his shaft and deep into his gut... making sparks dance through his eyes in near-orgasmic pops of sensation... but he could also feel his little filly pulling away from his girth slightly... he wasn't hurting her, but it was definitely uncomfortable for her to accommodate him.

"You're an ass, you know that?" Delta's voice came from the other room. Jet’s heart thumped for a moment, before he realized she was commenting about something she was reading… not on how callously he was stretching, breaking their daughter...

Still, it seemed appropriate at this moment… Jet gave one more shove, causing a naughty squelching sound to escape his daughter's fillyhood as he finally slid a quarter of the way into her, making her squeak out in shock.

With part of his massive cock finally wrapped in clenching, a writhing, hot filly-flesh. Jet slowed his incessant thrusting, letting his daughter adjust to the new size filling her… Allowing her tight filly-snatch muscles to relax around him, to mold themselves to his larger shape.

"S-sorry!" Jet groaned, partially to Delta and partially to Apogee - still whimpering slightly beneath him...

But it wasn't long before the instinct-enhancing effects of ZESPER roared back into the equation: the magical stimulants flooding Apogee's senses and turning her slight discomfort taking her father's massive shaft into near-orgasmic highs of pleasure.

Jet felt his little filly begin to melt around his cock… tension releasing from the clenched rows of muscles in her back... juices starting to flood again from her teenage pussy… the copious filly-flood trickling down the underside of his throbbing shaft… her liquid estrus-drippings trickling off of his testicles to the carpeted floor below.

Apogee groaned, her head still spinning... The latest kick of ZESPER stimulant was making her tongue loll out of her mouth as she overloaded on the magical and neurochemical stimulants pulling through her. The incredible fullness she felt in her lower body... the shifting of her muscles and organs to permit the huge stallionhood to enter her… it was all sending incredible feelings of pleasure racing through her body.

She wanted... no... she needed more.

The filly began to wriggle her butt left and right in little needy motions… pushing back against her father's unmoving granite mountain of a cock. Her muscles were on fire… her body leaking filly-juice... her head awash with hormonal and medicinal dopamine... BUT she was grinning goofily… her tail wagging with seductive happiness as she pushed back with her forehooves against her father… grinding her ass backward... trying to get more stallion inside her.

"Mmnnghh... c-c'mon Dad... P-please?" She whispered breathily… still worried about alerting her mother in the other room.

Jet Stream needed no further prompting.

He was never good at denying his little filly what she wanted, and now would certainly be no exception.

He placed his hooves on either side of his filly's athletic flanks, gripping her firmly about her hips to get a good hold on her... her hooves were completely suspended off the tall library table, and he didn't want to send her sliding across it into the stack of books piled on the other end.

With his hooves firmly anchored into the tight hip-flesh of his daughter, Jet Stream did what came naturally to all stallion studs inside hot estrus-laden fillies since time immemorial.

He thrusted.

Apogee buried her muzzle against the table as her father drove more of his length into her. Her squeaks softly dissipated into the warm oak of the tabletop as more and more stallionhood entered her… spreading the depths of her tight and twisting interior as it forced her immature teenage vaginal canal to stretch and part.

The feel was no longer unpleasant or uncomfortable though... it was amazing.

Jet bit down on his lip to stifle his groans as he slipped another thick inch of stallion-flesh into his daughter... His huge, fat, medial ring was finally pressing up against Apogee's grasping, quivering lips, preventing him from slipping more of his impossible girth into her vise-like, velvet tunnel.

The effects of the ZESPER on the middle-aged stud was incredible though... he could feel her grasping, massaging, milking muscles squeezing and caressing every part of his deeply embedded stallionhood...

This little girl under him… who'd called him Dad for so many years... that he'd taken to swim-meets... shown how to fly for the first time... taken to her first day of school… was now grinding herself against his cock... as he bucked her harder than he bucked Las Pegasus call-girls...

Jet Stream couldn't help himself. He snorted a huge puff of air from his stallion-ly nostrils and began to work his length back and forth inside his daughter... withdrawing with agonizing slowness as Apogee's snatch did its utmost to clench onto him and refuse him exit… Then Jet would reverse course, pushing forward again to elicit a sloppy, squelching drizzle of filly-juice... shivering with pleasure as he returned the inch he'd just withdrawn back into his little girl’s drooling honeypot.

These squelching sounds were growing louder and louder, making Jet look nervously at the french doors to his study... where Delta was currently sitting, obliviously.

He couldn't see her from his filly-mounted position but he knew that if Delta decided to walk back into the library there wouldn't be enough time for him to withdraw his steaming stallionhood from his filly and conceal their debauched sexual activity.

She would find out. He would be ruined.

And he didn't care one bit.

If anything, the ZESPER was making the unnecessary risk drive him even more wild... spurring him on to ignore the terrifying reality he found himself in, only moments from total ruin... making him use the fear as motivation to pound his teenage filly’s plot harder...

In and out, in and out.

The regular, slow pace of Jet Stream's heavy thrusts caused his balls to swing slowly back and forth as he loosened Apogee's powerful pussy-grip, slowly but surely. The copious, slick fluids of their union lubricated more and more length as he pistoned in and out of the little filly... her hooves grasping meekly at the table, trying to hold on as her father rutted her into oblivion.

Each time Jet would withdraw, he would drag Apogee back with him from the suction of her snatch... forcing her to brace herself by holding onto the table... Then he would slowly push back into her… her mewling sigh only ending once he reached the limit of his return stroke: his medial ring.

It continued this way for a few strokes until Jet felt something building, yearning in his balls: a familiar ache that began to assert itself insistently… urging him to abandon his considered pace... to buck wildly… to explode with lust into his girl.

“A-apogee…” he moaned into his daughter’s ear as the cascade of instinctive demand continued to crash down in his mind, collapsing his resolve to resist.

“Mnngh… Dahee…” Apogee moaned into the oak, her face twisting from left to right as she thrashed in pleasure… trying to keep her moans directed into the wood to stifle them. The pressure inside her snatch from the fattening and hardening flare was incredible. She could feel the bulge of her father’s massive cockhead pressing through her lower belly to the table below as it engorged further with blood.

But for Jet, it was now too late. The crescendo had already reached the point of no return as Jet delivered the instinctive, final thrusts demanded by evolution… burying himself as deep as he could in filly-puss before his loins released their hot load… the boiling heat racing up through his sexual plumbing and up his twitching shaft almost painfully... the pressure gushing and bulging his shaft outward from the powerful ejaculatory pulse.

“Anghh… Apo-... Ap... Ahhh...” Jet bit into Apogee’s neck, his moan becoming a grunt as his seed erupted out of his flare, a hot, messy burst of thick splatter rushing out of him in thick ropes of sticky semen, painting the inside of his little filly with line after line of white, passionate batter.

Spurt. Spurt. Spurt.

Apogee buried her face painfully against the table, biting her tongue to prevent from crying out as her body reacted with indescribable orgasmic bliss at the long-awaited presence of her father’s stallion-fluid. The prolactins and testosterone in his semen were absorbed like a sponge by her clenching, needy filly-walls… setting off fireworks in her nethers that spread like a warm wildfire, racing up the sides of her barrel and all the way up to the tips of her ears.

Spurt. Spurt. Spurt.

Jet released rope after rope, his cock bucking up and down with each powerful spray, hopping wildly in his daughter’s snatch as it unloaded. Little cupping thrusts from Jet’s strong hips continued their instinctive work... driving his shaft in and out ever so slightly, his motions meeting the gentle milking clenches of the little-filly’s needy cunt.

Spurt. Spurt. Spurt. Splorch.

Apogee felt her uterus convulsing, quivering… dipping its opening down with each milking grasp of her inner-muscles to bathe her cervix in her father’s batter… slapping the portal to her wings against his still spurting cock-slit with little kisses as her climax continued to wrack her body. She began to feel the thick semen squelch noisily from where her filly-lips joined her father’s shaft, splattering to the table below… she had been filled.

Spurt. Splorch. Spurt. Splorch. Spurt. Splorch.

Jet Stream moaned into his daughter’s neck. He could feel the heavy dollops of steaming cum shooting out from between his daughter’s lower lips and his throbbing stallion-hood… and he knew that he had much more left to fire… just like earlier at the kitchen counter-top, he seemed to be unstoppable... releasing more seed than he ever had in his entire life… before this morning that is.

Jet thought of his groaning, happy daughter underneath him, her wriggling, milking convulsions demanding even more of him, even though he had given everything. He thought about her smiling face, the boundless enthusiasm and energy with which she attacked everything... the way that she turned to him as a filly for help when she felt lost... how she would snuggle up to him when he’d fall asleep, exhausted after a long day of work on their couch… how as a younger filly she’d run up to him, teary-eyed when she’d hurt herself, asking for a bandage or a kiss to make her boo-boo feel better…

...and here he was now, mounting her... rutting her… defiling her most secret inner sanctum. He had fully claimed her.

But he wanted more… his tongue stuck out as his stallion instincts took over.

He wanted to mark her. To let everypony know that this was his filly.

Spurt. Splorch. Spurt. Splorch. Spurt. Splorch.

He pulled back, still shooting thick lines of semen… his massive and engorged flare acting like a thick plug as he withdrew, spreading Apogee wide and dredging unspeakable amounts of their combined juices out.

A nasty squelch accompanied the exit of Jet’s cockhead, making Apogee wriggle with discomfort as the pair finally disconnected with a pop... leaving her gaping, steamy pussy quivering and clenching, begging for his return.

Spurt. Spurt. Spurt.

Jet wasn’t driving back in though… he was marking this filly for his use.

He slapped his thick meat up onto her flanks, his fat flare perched over his prone filly… the heavy ropes of still-spurting semen slinging out over her back, splattering along her spine and outstretched wings. The thick clear paint slinging out with maintained heavy bursts of juice, just like earlier in the morning… only now he wasn't slathering his kitchen counter… it was his daughter.

Spurt. Spurt. Spurt.

She was his.

Jet aimed his larger, longer stallionhood slightly up, sending arcs of his spurting seed all the way into the back of Apogee's sweaty mane… strands of sticky white splattering against her neck, her ears… as if he were sloppily painting her with a clear white gel.

Spurt. Spurt. Spurt.

Jet pulled back, using a hoof to direct his bucking cock at Apogee’s flanks, firing more ropes over her quivering butt-cheeks and against her sloppy, drooling plot.

Spurt. Spurt… Spurt….

A few final burst trickled from his cockslit, leaving messy trails that connected his flare to Apogee’s tail, as little bubbles of cum slid from his flare and drooled down his shaft.

He’d done it.

He’d claimed her.

…

He stood there for a moment, panting, looking at the absolute disaster of fluid that he had wrought on his daughter… her heaving, panting barrel resting on the messy tabletop.

He exhaled a powerful snort through his nostrils… he felt like nickering, but the last vestige of sanity that he held onto prevented him from doing so and revealing his deeds to Delta, still reading in the other room.

Still, he couldn’t help but puff up his chest, his erect penis still rigidly bouncing under his barrel, proud that he had bred this little mare so completely…

And then Apogee lifted her head and looked back at him. Her eyes were aswim, her cute little muzzle hanging slightly open as her tongue darted in and out with panting breaths. She seemed to be unable to focus on anything for a few moments - she was still trying to understand what had just happened.

And then their eyes met.

Slowly, understanding dawned on her face as she read her father’s wild stallion-like attitude in his features… and then she grinned. Her eyebrows danced, challengingly… she was a wild, untamed, filly. He hadn’t broken her yet.

He’d change that.

With a mighty flap of his wings, Jet lifted himself onto the library table, positioning himself directly over his daughter, his hips aligned with her sopping rump. With a little bit of excited fear, Apogee clambered forward, as if trying to escape from her father… but he wasn’t going to let her…

Aligning his thick, hanging cock… he placed the drooling, shiny head against her flanks and pushed down. Apogee's loosened, sloppy lips permitted him entrance immediately... the fillyhood slid effortlessly over his cum-covered flare… her slick lips slipping over his flesh like a pink glove.

Jet Stream continued to jackhammer down into Apogee’s butt, pinned against the unyielding tabletop, even as she continued to scoot forward, as if trying to escape… He’d stop that little game right now.

He reached down and gripped her shoulders with his forehooves as she thrashed playfully under him… then he let his weight fall fully onto his shaft.

He immediately sank a few thick inches into her with a squelching thrust… driving himself all the way to his medial ring again... bulging Apogee's little belly once more.

Apogee squeaked out, kicking in all directions with her legs... her forehooves were now in reach of the books on the other end of the table and knocked down a pile of them, making them clatter noisily to the floor.

Both froze immediately, looking silently at the french doors to the study… would this be the end?

"...everything OK in there, kid?"

Jet Stream chuckled to himself, now it was his turn to live dangerously. His turn to tease Apogee... He began to add more and more weight to his shaft, pressing with all of his bulk against his daughter’s yielding lips, which strained and strained, trying to part to let his massive cock-base in.

"Everything's f-fine... m-m-MOM!" Apogee squeaked.

Apogee squeaked out just as her lips finally slipped around her father’s ring, the fat black cock sliding deep into her, pressing his huge cockhead against her uterus even as her lips stretched… the swollen folds straining as they approached the fat, monstrous base of his girthy shaft.

She had never felt so full before.

Yesterday had already been incredible… this… this was something else. Her whole body seemed to be adapting, changing itself to permit the massive stallionhood into her. It wasn’t just her clenching walls, her tensing muscles, her shifting internal organs… it was her very spirit.

She felt like her father’s cock belonged in her… this size... dominating her, filling her… completing her.

And then Jet began to move.

Slowly at first, withdrawing by merely standing up with his legs... taking the weight off of his filly the impossibly thick, black veiny shaft inched out of her... then he would reverse, adding his weight back... bending his knees and sinking with nasty-sounding splorches into her spasming fillyhood.

Faster now… finding a rhythm of straining and relaxing, of rising and sinking… each cycle lifting his daughter slightly from the tabletop before driving her back against it… each time sinking a little bit deeper… plumbing her depths and claiming every part of her.

Then, with some violence… a jack-hammering pounding began, books hopping up and down on the table with each thumping drive. A small part of Jet’s mind screamed at him to stop, to slow down… there was no way that they wouldn’t be heard by Delta like this… but the tiny internal voice was quickly dwarfed by the overwhelming flood of lust-filled neurochemicals surging through him…

It seemed to be going the same for Apogee, as books clattered about her, falling to the carpeted floor from their perch on the tabletop. She began moaning again, her breathy pants no longer restrained by biting on a book or being muffling by the wood of the tabletop.

“B-buck… buck…. BUCK me!” She groaned, her words punctuated with each jackhammering thrust… and Jet Stream was happy to oblige.

He let out a roar that filled the library, his wings spreading wide as he asserted himself, his muscles straining and sweating with the effort as he pounded his filly’s snatch with all the effort he could muster.

“D-daaad…! T-too… too b-big!” Apogee shouted out, finally feeling her father hilt his new stallionhood in her... his hips finally slapping against hers with his never-ending power-thrusts.

The table tipped wildly, jumping along the carpeted floor as the father-daughter duo sweated and groaned, pistoning their bodies and spurting juices with reckless abandon…

Then it gave way.

Jet wrapped his arms around his daughter, tucking his shoulder and giving a mighty flap of his wing as they tumbled through the library, into the office… splinters of wooden table legs and books flying about like the shrapnel of some lust-bomb.

Apogee twisted about, trying to grab her father’s barrel... the adrenaline of the sudden fall momentarily overshadowing the uncomfortable feeling of such a large organ twisting around inside of her, moving everything in all different directions.

The filly would be lying if she said the excitement didn’t rush through her as well… the suddenness of the fall combined with the comforting safety she found in her father’s grasp made her filly-muscles clench and milk the stallionhood inside her with small, grasping convulsions.

The pair finally slid to a halt, in the middle of the office, Apogee having twisted to face her father so that they were now belly-to-belly.

Jet didn’t hesitate, didn’t even care that the balcony door was open… that Delta had just flittered away moments earlier, before he began to grind in and out of his little filly again, making her throw her head back and groan.

“D-dad… p-please!” She begged.

It was enough.

Jet felt his flare fatten once again, even though he’d completed his orgasm just moments before… but, he grinned to himself, this filly was going to be a challenge to tame. He almost chuckled, even as the blissful tightness of his abdominal muscles began to overwhelm him... his orgasm mere moments away... she was a greedy little filly, after all.

“D-daddy!!! YES!” Apogee reached up with her rear hooves, wrapping her father’s hips to keep him hilted deep within her as he erupted, pulling him against her with her legs and keeping him locked against her. Buried in her.

The fattened flare had embedded itself deep in Apogee’s love-canal, wedging itself in position against her swollen cervix, perfectly positioned to flood her uterus.

And flood it did.

Pump after pump… no longer splattering into Apogee’s vagina to trickle out and be wasted on the tabletop… now he was filling his daughter’s womb with his potent seed.

Jet’s testicles raised and twitched in time with his pumping pulses, thick load after thick load filling into his daughter. He leaned in with his nose, nuzzling her head as she wrapped her fore-arms around his neck tightly... hanging on to ensure that she wouldn’t get displaced… wouldn’t lose a drop of her father’s batter.

“Unnghh… y-yes… d-dad.” Apogee groaned, coaxingly, as her body milked his stallionhood. Her belly expanding as her father dumped his magically enhanced volume of stallion-milk into her.

A few more pumps, and Apogee felt herself passing out… fully satisfied. Her legs slipped from their death-grip of a hip-lock, thudding lightly as they fell to the office’s floor. Her fore-arms unclasped her father’s neck, as she lowered herself, letting her head rest on its side as her eyes fluttered closed… her pants still coming in time with each thick, filling pump of stallion-essence from her Dad.

Jet Stream grinned. He’d won this round.

As soon as Apogee had finally fully relaxed… melted away into blissful euphoria, he stood up, withdrawing himself from her body.

Spurt. Spurt. Spurt.

Still spurting, he let his black-veined, bouncing flesh unload rope after rope out over his filly’s cute, furry belly. Thick white cream strands landing on the fluff of her adorable heaving chest, trailing down over her pert teats, before a new strand would fly out, splattering across her muzzle and neck.

Spurt. Spurt. Spurt.

He directed his shaft with his hoof, like a lewd spray-gun, aiming for parts of her fur and feathers that seemed untouched. He would claim her… mark her… own her in her entirety. He was her stud and he’d make sure she… make sure everypony… knew it.

Spurt…. Spurt...

Once again, he felt the force of his ejaculations relent, the throbbing, swollen ache of his testicles relieving themselves as a wash of post-ejaculatory pleasure crashed through him.

Then he came to his senses.

“Wh-what the buck did I just do!?” Jet stared down at his cum-covered filly, softly breathing despite the sloppy mess he had just made of her, as he had lewdly painted her with his stallion-juice.

Jet knew he’d crossed a line. He’d just purposely cum all over his little girl… tried to defile her… to make her his little sex-filly. He hadn’t given a damn about how she felt... And he’d loved it…

He dipped his head to her panting, tired face, the concern on his features readily apparent as his stallionhood deflated rapidly… what had he just done to Gee? To his little hun? To his little girl?

He felt tears building up within him… and he shut them quickly, trying to blink away the hot trickle forming in the corners of his eyes. In the darkness behind his eyelids, he tried not to imagine the worst - the monstrous consequences of his domination.

Then he felt it.

A little wet touch on his nose.

He opened his eyes.

He saw his little girl, Apogee, though she was covered in his batter… with the most satisfied smile on her face before she leaned forward one more time and laid another loving lick across his muzzle… a silent and cute ‘thank-you’ for what they’d just completed.

It clicked then.

Jet Stream realized, he loved this little filly, that he would do anything for her… damn the consequences… just as he always had. To be able to see her happy like this… satisfied… if this is what she wanted.

This is what she would get.

“Th-thanks… A-Apogee… hun.” Jet Stream managed to choke out.

Apogee reached up with her hoof, booping her father on the nose. “Th-thanks yourself, Dad…” She blushed… “That was pretty amazing… c-could we do…”

“Do it again?” Jet Stream finished her question with a little eyebrow waggle. “Tell you what hun, I’ll make you a deal… one time only, OK?”

Apogee nodded happily, her smile getting wider as the kid in her knew that this was the inevitable phraseology that came just before she’d get everything she wanted.

“Just until your heat is done… until your estrus clears…” Jet blushed, and looked up at the ceiling… “I-I… I’m yours… a-anything you want…”

Apogee squeed, shaking with excitement, before lifting her back off the floor to wrap her father’s neck in an excited hug, “THANKS DAD!”

Jet Stream sighed, even as he felt his nethers begin to stiffen again.

He had a feeling he was in for a hell of a night.

Apogee broke her hug for a moment, an arched eyebrow of confusion on her face.

“W-wait… where did mom go?”

A few minutes earlier…

Delta had just spotted an unusual document, something she hadn't expected to see here of all places…

A fading, yellowed, thick-bound set of design documents...

'Design Thesis for a Reusable SSTO Spaceplane' by Jet Stream and Delta Vee

She held a hoof to her chin in wonder. It was the original thesis paper that she had written some 16 years ago...

To be fair, Jet's name was on it too... but Jet had only done the work around commercial aspects of reusable technology, the cost-breakevens of various materials and fuels... the easy stuff...

Well, she did have to admit he had also contributed some brilliant work in designing the aerofoils that would work as equally well at low-speeds as they would at high-atmosphere hypersonic velocities.

Still... she'd been the one to do the important work. The engine design. The fuel turbopumps. The rocket stack. The rocket nozzle design. Hay, the air-breathing RAMJET engines she'd envisioned alone had kick-started a whole new generation of jet-engine technology... which had propelled Jet Stream to the head of a multi-billion bit airliner corporation.

Delta's breath left her for a moment as she touched the faded document reverently. She hadn't seen this in... well... forever. Did Jet keep it out on his desk just to remind himself that he'd taken everything from her?

Delta felt her face begin to twist up into a growl as her anger rose. "So I see you kept our thesis documents kicking around... must be fun to gloat to yourself about how bad you screwed me over!" Delta called over her shoulder to the library behind her.

"N-n... No!" Jet mumbled from the other room.

Delta harrumphed, ignoring him and flipping open the the thesis. She was struck with an unwanted up-swell of emotion as she immediately recognized the familiar hoof-writing style of a much younger Delta, who had penned the foreword in front of her so many years ago.

'...represents years of work during our time at Coltumbia University. Jet and I would like to thank the school and all of the faculty for their incredible support. Jet and I are both filled with hope for a beautiful future where our reusable spaceplanes convey our warm love, the love of Equestria, to the stars! - Delta Vee'

Delta sniffled a little bit, feeling her eyes get a bit misty as her emotions rose within her... that poor kid had no idea what was waiting for her... she was still so full of hope and purpose.

A frown crossed her face and she shouted over her shoulder again. "You're an ass, you know that?" Before she turned the pages of the thesis to access more of the old text.

A squeak from Apogee peeped out from behind her. Probably a bit shocked at her sudden profanity, Delta mused. Then she heard Jet say. "S-sorry!"

Delta snorted, she didn't want his half-assed apologies more than 16 years later. She felt her rage building as she flipped through the familiar texts, the old diagrams and technical tables that she'd slaved to create... before she began to be annoyed by all the notes in the margins, notes she didn't remember ever writing.

She tried to decipher the spidery handwriting, which she now recognized as clearly belonging to Jet Stream... and finally was able to understand one particular note, dated 10 years earlier:

"...can't figure out what DV meant with this bypass valve system... it's obviously important but it's really heavy. I asked the engineering guys at the company and they couldn't figure it out either... they told me to get back to designing jetliners and leave this spaceplane stuff behind. But I can't... I can't let our dream die, let DV's old dream die.

I was going to ask Delta about what this meant yesterday, at Apogee's first swim meet. But she didn't show up. Probably getting wasted somewhere... Because of me.

Hope she's OK."

Hmmph. If those idiots couldn't even understand a simple air-driven coolant fuel bypass then they didn't deserve to be engineers - why should she have to hold their hooves all the time.

Delta flipped to another page and another note in the margin she could read, this one from a couple of years ago.

"...brilliant. Brilliant. Brilliant. Once again I'm beside myself with how clever DV was. I think that's what always drew me to her... it was like a gravity well, her incredible intelligence! I mean, look at this variable inlet design! And it self-adjusts based on the exhaust temperature for optimum efficiency!

...But in reality I think it was always DV's heart at the center of that gravity well. Some days I miss her, the old DV.

Apogee was almost brought to tears when Delta didn't even bother going to her school play. Gavel told me later that she'd been incarcerated for drunk and disorderly behaviour.

I wish I could help her, but I just make things worse.

I'm sorry DV. I'm sorry Delta."

Delta blinked, feeling tears forming in her eyes. Why did Jet refer to her separately as DV and Delta?

She heard a clatter of books fall from the library table behind her and then a stifled moan from Apogee.

"...everything OK in there, kid?" She asked, looking back at the open doors but unable to see anything from this angle... had the kid taken a spill or something?

"Everything's f-fine... m-m-MOM!" Apogee squeaked.

Delta shrugged and turned back to the thesis, flipping to one last page which seemed to be covered in red ink from the notes in the margin which scribbled messily along the entire page. She took her time reading through the original text, a boring piece about minimizing lateral vibrations during the transition from air-breathing engines to rocket-powered exhaust thrust, before turning her attention to the sloppily hand-written note in red ink.

It wasn't dated.

"I hate Delta.

...I had to pick up Apogee today from the junkyard and she was inconsolable. She ran to her bedroom and cried for hours.

I don't know what that mare told her, but if it's anything like the venom she spits at me... she probably told our daughter that she was the worst mistake of her life, or something equally vicious.

...

I'd held out hope after all these years that DV's good heart would come back to us. To me. But we end up with the booze-saturated, withered blackened husk of a heart that Delta has cultivated.

I've written in these margins for years, lying to myself that it's only because I need to better understand the original design of our dream - but the reality is that I have been haunted by DV, haunted by her transformation into Delta.

A transformation that was my fault.

Every time I think about the company I built, about the connections I've made, the wealth I've accumulated - I know deep down that it's all just a shield, a second-place prize... I wanted DV to be with me during all those moments. I wanted her to be there, smiling, dreaming... looking up at the stars, by my side.

I was such an ass all those years ago.

I loved DV.

I still love her. I started all these notes to try to banish her from my desires - to stop me from feeling down when I'd wake up with another call-mare next to me that wasn't DV... and it became this diary of me remembering the good times... and the bad.

It's got to stop. The hope I held out for Delta is fading fast, and if orbital mechanics have taught me anything it's that we need to jettison dead weight if we'll have any chance to make it to our target altitude. I don't mind being weighed down, since I was responsible... But... What she is doing to Apogee is inexcusable.

I don't know if I'm going to write any more notes - I think I may be done.

...

But still... I love DV, I miss her. And because I know she's in there somewhere... I guess...

...I guess I love Delta, too."

The last word, 'too', became a blurry mess of splotchy red as a drop of liquid fell onto it. Delta looked up surprised, expecting to see a leaking ceiling, only to find nothing there.

She reached a hoof to her face, touching it lightly and feeling dampness there.

She was crying.

...

This sucked.

Delta pushed away from the desk, shakily reaching for her pack of cigarettes with one hoof as the other tried to rub her crying eyes clear... but her shaking forearm was having trouble extracting the pack, so she gave up and brought her hoof down with a frustrated slam on the desktop.

What the hell was with all that DV and Delta crap... she was DV... he was the asshole who'd made her Delta.

Wait.

There was nothing wrong with being Delta, was there?

...

Delta took in a choking half-sob of a breath, tears running freely down her cheeks now.

...

Screw this, screw having come to this stupid apartment, screw trying to be a mom and a better pony.

She needed a drink.

...

Delta snatched the thesis document, and opened the sliding glass door to the balcony.

"I'm outta here, I'm late to an appointment with a bartender." Delta called out over her shoulder, as she stomped out onto the balcony. "Take care of yourself kid... Jet."

And she flew off, just like that.

Wow, almost forgot to put in an A/N after all of that work!

First and foremost I have to thank my suite of editors. Rei gets top mention as he has been helping me from the very beginning and was instrumental as we charged through to completion on this chapter.

Next my proof-readers... PBerry - TankDrill and Number Eight. You'll find all of them on FimFic and they were all a huge help in getting this out to you.

Finally, of course, to Shino who made this crazy universe in the first place!

Thanks to all!

Regarding the fic itself... it was a lot of fun to continue world-building and working around some of the challenges of not knowing everything in the creator's head as I went along. Bringing Delta into the fray was difficult, but very rewarding!

I really hope I didn't leave anyone on too much of a down-note with Delta having read what amounts to Jet's journal...

Let's just say my editor Rei may have something in the next little while that explores Delta and her story a little bit more... and of course the main blog will too!

Finally, if you liked my Apojet smut, I'm happy! At the end of the day I'm primarily a raunch writer... if I can pull some heartstrings along the way, it's just a bonus!

Thanks! CFITC.
