Why did she have to be so fucking big?
It wasn't really Lyra's fault, Bonbon supposed. She couldn't help being so enormously well endowed any more than Bonbon could help her own healthier-than-normal libido. It was ultimately the cruel mistress of genetics that had led to the torturous situation she had found herself in. But still, why did she have to be so fucking big?
When they'd been younger, Bonbon had been the larger of the two. Puberty had hit her early and generously. Early enough that it hadn't had any real impact on their friendship – Lyra was too young to care that Bonbon's breasts were bigger than hers. Not long after that Lyra was accepted into Princess Celestia's School for Gifted Unicorns, and her move to Canterlot had likely prevented it from ever becoming an issue in the future.
Of course, at the time whatever potential benefits there might have been to Lyra's departure never crossed Bonbon's mind. All she knew was that her best friend was going to be going far away and wouldn't be coming back for years. For someone as young as she was at the time, they might as well have said she'd never see Lyra again. Her parents eventually managed to calm her down by helping her write a letter, stamp it, address it to Lyra, and mail it off. The reply she'd received a week later had felt more like magic than any actual magic she'd encountered.
She wrote her own reply, and the two quickly settled into a routine of keeping in close contact via mail for over a decade. Hundreds of letters were exchanged, chronicling the mundane details of their lives. They talked about school, work, friends and acquaintances. Lyra complained about the hassles of everyday life in a big, crowded city. Bonbon complained about Ponyville's crippling lack of modern conveniences. It became just another part of her daily routine – every Saturday she got a letter from Lyra, every Sunday she wrote a reply.
Until, one Saturday a few months after a particularly eventful Summer Sun Celebration, the routine was changed. “Hey, Bons!” Lyra had written. “Who has two thumbs and is finally fucking done with school? Me! I'm gonna be moving back to Ponyville in a week or so (sorry for the short notice!) and I figure you're gonna wanna finally hang out face to face instead of just exchanging letters like chumps.”
From there events seemed to unfold at a breakneck pace. Bonbon offered to let Lyra stay in her guest bedroom until she got properly settled in, found work and such, which Lyra had eagerly accepted. Bonbon spent the ensuing week desperately scrambling to create a guest bedroom from nothing. And then the day finally arrived. Bonbon spent most of it lurking anxiously by the door, waiting impatiently for Lyra to arrive. It felt like an eternity before there was finally a knock, and Bonbon immediately threw it open. “Lyra! It's so good to finally see y-.”
At which point she finally got a look at Lyra and her words dried up in her mouth.
When they'd been children, Lyra had always been smaller than Bonbon. It was a simple matter of genetics – Unicorns tended to be small and thin, Earth Ponies were big and stocky. The two of them had been a fairly good representation of that. Lyra had been a waifish, tiny thing, while Bonbon had been tall and wideset, even before early puberty had given her a set of impressive tits. By the time she'd finished growing – long after Lyra had left to pursue higher education, of course – they had reached twice the size of her head. Bonbon had never been a very vain pony, but she couldn't help but take some amount of pride in being one of the biggest in Ponyville.
Lyra's breasts blew hers out of the fucking water, no contest. Where Bonbon's were twice the size of her head, Lyra's were at least twice the size of Bonbon's. They dominated her torso, big and heavy and almost comical on Lyra's otherwise slender body. Fist sized bulges made it abundantly clear that she hadn't even attempted to wear a bra under her plain white tee shirt. Likely she was simply too big for underwear to be more feasible than just buying shirts with support enchantments. There was only the slightest hint of sag, just enough to show that they were one hundred percent natural. “Uh, hi!”
“Hi,” Bonbon managed to reply, forcing the words out of her suddenly very dry throat. “You've, uh, you've definitely changed a lot.”
“Yeah, 's a long story. Would you mind giving me a hand? I think I might be a bit too wide for your front door.”
Bonbon circled around behind Lyra and dutifully helped her squeeze her tits in to the point she could fit through the narrow door. She could probably have fit through without help, but Bonbon didn't feel like pointing that out. Her hands sank deep into soft, warm, pliable flesh, and she stifled a quiet moan. “Hey, uh, careful there, Bons.”
“Oh! Sorry.” Bonbon loosened her grip and pushed Lyra the rest of the way through the door.
“Whew, almost got dangerous there for a bit.”
Bonbon could feel a bright red blush spreading under her fur. She might have gotten a bit eager considering Lyra had only been in Ponyville for a few minutes, but they felt really good to just squeeze. She shook her head in an attempt to clear out the lewd thoughts. Clearly Lyra didn't mean it that way. “Sorry,” she repeated.
“It's okay, you didn't really know.”
“Know what?”
“It's, uh, a glandular disorder, I guess? It's, uh, kind of embarrassing, which is why it never came up in our letters. And I don't even pretend to understand more than maybe a third of what the doctors told me back in the day, so I couldn't really explain the why or the how to ya'. Just the what.” She gestured, grinning nervously, at the what. “The short of it is that around when I was like fifteen or so, they got really, uh, really big. 'n leaky. Hence, uh, the whole dangerous thing.”
“Okay.” So it hadn't been a sex thing, then. Bonbon felt briefly disappointed, and then briefly ashamed of herself for feeling disappointed. “Well, unless you need some kinda special accommodations, we're probably fine.”
Lyra actually had needed a few special accommodations. No extensive alterations to Bonbon's home were needed, at least. But Lyra simply couldn't fit comfortably in any bed smaller than queen sized. They'd had to set up a futon – acquiring a proper bed that fit Lyra in less than a week was out of the question – and Bonbon gave the twin bed she'd bought prior to Lyra's arrival to goodwill. It had been quite expensive, but as far as she was concerned it was worth it.
“I dunno how comfortable I am with spending this much money on me if I'm only staying here temporarily.”
“Well, why don't we make it less temporary? You can stay as a friend for now, and once you get a proper income set up we can say you're renting the room.”
“That seems fair enough,” Lyra replied. “Now, if you'll excuse me, I've been on the road all day and these girls aren't exactly lightweight. I'm gonna pass out, seeya tomorrow!”
It took less than a day for Bonbon to realize regret her suggestion. Lyra wasn't a bad roommate, of course. And she certainly didn't mind living with her best friend in the abstract. But, well.
Lyra was distracting. Extremely distracting. Bonbon had a very, very healthy libido – and, more pressingly, didn't really have any outlet for said libido aside from masturbation.
Lots of masturbation.
Even before Lyra's return she'd had to take the occasional day off of work to deal with her mounting frustrations. It had never really cut into her profit margins, of course, or she'd have found a permanent solution by now. But her store, modest as it may have been, was one of exactly two places to get sweets in Ponyville, and Bonbon's candies and confections filled a completely different niche from Sugarcube Corner's pastries and baked goods. Her customer base was sizable and loyal enough that she could afford to close the store down occasionally.
Of course, that was before Bonbon got a housemate with tits the size of beach balls that happened to lactate copiously. Her days off stopped being once every few months and turned into as much a part of her weekly routine as exchanging mail with Lyra had once been. Still not quite enough to seriously damage her profit margins, but Bonbon found those moments when she had to excuse herself to masturbate coming more and more frequently with every passing day.
What she needed was some form of proper sexual release. She couldn't, as she found herself at the moment, keep on spending entire days locked in her room masturbating to idle fantasies of Lyra's gigantic tits. All that seemed to have accomplished so far is making things worse. It was with a sinking feeling that she realized, even as she bucked and stroked and groped at her sweaty, naked body, that she was going to have to confront Lyra. She no longer had a choice – the risk that her business might start to suffer was simply too great. Either she found some way to let loose her massive excess of sexual energy or, more realistically, Lyra was gonna have to go.
Bonbon grunted as her masturbation sped up. The unpleasant task of kicking her best friend out on the street could wait until she was finished. Her bed began to creak and groan as, with a mounting tightness in the pit of her stomach, her hips began to buck. Slowly at first, but with a mounting speed and intensity as she barrelled down the road to orgasm at top fucking speed. She tried her best not to be too loud, lest her housemate catch her in the act, but she produced just enough noise that she didn't hear the faint sound of footsteps approaching her bedroom door until it was far too late.
“Oooooh Lyra, I'm gonna-”
“Hey Bons, I'm gonna go grab some groceries. Would you mind giving me a hand?”
Bonbon briefly panicked, before remembering that she always locked the door whenever she wanted to let off stress – even when she'd lived alone, just in case. “Ah, gimme a minute Lyra, I'll be – mnnn – I'll be right with you.”
“You okay in there, babe? You sound... weird.”
“I'm fine!”
“You sure? You've been spending a lotta time in your room lately, and – man what is that smell? Yeah okay hold on, I'm gonna come in.”
“Door's locked!” Bonbon shouted even as she realized with a sinking feeling in the pit of her stomach that the doorknob was turning effortlessly. Maybe she'd been in too much of a hurry to remember to lock it, or maybe she'd subconsciously left it unlocked in the hopes that something like this would happen. Regardless of why, though, the door was unlocked. She had seconds before Lyra barged into her room and learned the truth, and she was already so close. Bonbon squeezed her eyes shut as she attempted to pull her hands away from her body.
“Seriously, Bonbon, you don't need to worry about making me wo- Sweet mother of Celestia!” Lyra exclaimed as she entered exactly in time with Bonbon's horsecock letting out a good gallon of sticky off-white gunk. Given the short notice, there had been no chance that Bonbon could have hid it in time. It was just too fucking big – it was three and a half feet long, coupled with a set of fat heavy balls that rivalled her tits in size. Hell, it had been all she could do to aim its copious eruption away from Lyra's face. “Okay, uh. That's new. I'm pretty sure I'd remember you having one of those before.”
“I usually wear enchanted panties to hide it,” Bonbon muttered even as her hips kept right on bucking and bucking and bucking. Several more eruptions shot their way across the room, painting the opposite wall white. “Shit, Lyra, hold on and let me deal with this then we can talk okay?”
“Actually, you know what? This explains a lot.” Lyra sighed. “Geeze, Bons, you shoulda said somethin' sooner. Like, day one at least.”
“Lyra please leave.”
“Heck no, this is basically my fault.” Lyra crossed her arms on top of the expansive shelf of her tits. “Like, you masturbating in your room every time my tits turn you on is clearly not gonna cut it if we're gonna live together holy shit. Sit,” she commanded.
Bonbon stared blankly, or at least as blankly as she was capable of while her hips continued to buck involuntarily. Her cock, at least, had stopped for the moment, but she could feel herself teetering on the edge, ready to plunge into the metaphorical depths at the slightest provocation. “I, uh. Lyra could you just gimme a minute to cool down a bit before we tal-”
“Sit, Bons.”
“I am sitting.”
“No, like, on the edge of the bed. Right now you're kneeling and I need you to be sitting okay? Sit.”
“Okay, okay, I'll sit,” Bonbon grumbled even as she complied. She shuffled her way along the bed, trying not to groan as her fat balls rubbed against the mattress with every movement of her body. “Okay there I'm sitting what n-”
“Shhh. Relax, Bons, just lemme handle this. Push your dick down a bit. Not too much, just like angle it down a bit.” Bonbon silently complied – Lyra clearly seemed to have some sort of plan. “Little bit lower. Okay, that should be good, hold it there for as long as you can handle.”
Bonbon wanted to ask exactly why she was pushing her dick down, but every other time she'd attempted to question what was going on she'd been shushed – besides which, she wasn't nearly naive enough that she couldn't figure out where Lyra was going with this. She was nervous, of course, but she was definitely okay with the direction the encounter had taken.
Lyra took a few steps forward, quietly sizing up the situation. She seemed almost hesitant, a jarring contrast to how in control of the situation she had seemed to be moments earlier. She took a deep breath and placed her hands underneath her assets, hefting them up slightly and positioning them over Bonbon's flared head. “Okay, so, uh, fair warning babe, I've never done this before.”
“Wait, wh-” Bonbon didn't get a chance to finish her statement when Lyra let her tits drop. In one fell swoop, she found her cock completely enveloped in gigantic breastflesh until Lyra pushed her body forward and it popped back out – Bonbon felt an oddly out of place surge of pride at her shaft being gigantic enough that even Lyra's behemoths couldn't entirely contain her. Which was very quickly replaced with an entirely different surge as Lyra again placed her hands below her tits and lifted.
Bonbon was a virgin. It wasn't something she was particularly proud or ashamed of – it was just a fact. She'd masturbated, of course, quite a lot. But that wasn't remotely the same thing as having her needs tended to by another pony, face to face and hands on. She didn't regret her lack of experience, but it left her with no point of comparison for how good it felt to get her cock squeezed by Lyra's gigantic tits. Lyra's body felt so warm. Her breasts squeezed tightly against the towering shaft, held in place by the slightly too small white cotton t-shirt she was wearing. Bonbon didn't have the words to describe what it felt like because it was like nothing she'd felt before. They were soft and pillowy, like clouds, but at the same time they pressed so tightly together that there was barely enough room for her rock hard cock.
And they were moving. Not a lot – they were simply too big for Lyra to do more than heft them up a bit and then let go. “Sorry if this isn't great, they're kinda heavy. 's been a while since the last time I, you know, drained them,” she said before leaning in and gently giving the exposed shaft a slow, luxurious lick.
“Gnnnn,” Bonbon responded wordlessly. She could feel her balls pulling tightly against her body as her hips rocked and then bucked involuntarily. The base of her shaft bulged, pressing against its busty prison as her copious load made its way to freedom. “Gnhaaaaaannnnggg~”
Bonbon's wordless vocalization was accompanied by a second climactic eruption of thick white fluid. It rose high into the air before arcing heavily and splattering back downwards. Globs landed in Lyra's hair, while others thoroughly coated her shirt, and a good amount pooled in her cleavage. Bonbon let out another noise of pleasure along with the second copious gout before the first had even entirely finished, and then another and another and another, more than twice her earlier release with no signs of stopping. Gallons of the stuff rained down on the two of them, leaving them sticky and wet and so completely and thoroughly coated that all but the most virile of stallions would look practically impotent next to Bonbon.
“Geeze, Bons. You really were backed up.” Lyra slowly moved backwards, Bonbon's very well lubricated member easily sliding out from the tight tunnel of tit. “Well, hopefully at least now you've calmed down enough we can talk properly.”
“Uh, not- ooooooh fuuuuuck~” Bonbon attempted to speak, interrupted by yet another few gallons of spunk.
“Hm?”
“I mean it felt good, but, uh. I'm not really done yet.”
Lyra blinked, unsure of how to react. She opened her mouth, closed it, opened it again, and still struggled to find adequate words. “Seriously?” Her voice was part exasperated, part surprised, and very much impressed. “You just came, twice, enough to-”
Whatever metaphor Lyra was going to use was interrupted by Bonbon. “I didn't cum.”
“... I'm sorry?”
“That wasn't an orgasm. Just, uh, precum.” Bonbon's voice was strained and mumbly, forced through clench teeth in sharp, staccato bursts of sound even as her hips continued to rhythmically buck.
Lyra opened her mouth to respond, but no words came out. Just a quiet, strained gasping noise. She stared in quiet awe at Bonbon's shaft, throbbing, harder than ever, and she could swear it had gotten bigger. The silence would have been deafening, were it not for the wet noise of Bonbon's drooling member unleashing more precum in regular gouts. “Sweet mother 'a Celestia,” she eventually managed. “You're still, uh. You're still ready to go then?” Her voice squeaked, like a nervous teenager.
“If anything I'm more ready than I was earlier,” Bonbon managed to force out in a low groan. “Just leave, I'll deal with this and then we can-”
“Fuck that shit, like hell am I missing the opportunity to have that thing in me,” Lyra snapped as she unceremoniously tore off her shirt before tossing aside its cum-stained remains. They were at least as impressive bared as they were clothed. If not moreso – without her shirt squeezing them together they seemed to be a good bit bigger. They hung heavily, dominating Lyra's torso, but even without her shirt there wasn't the slightest hint of sagging. They were firm and round, while still having just enough real weight to them that it was clear they were entirely natural.
And she was leaking. Copiously. Nipples the size of fucking soda cans, twitching slightly as twin waterfalls of milk flowed down their length. Bonbon wasn't sure how she'd not noticed them when Lyra'd been clothed – presumably the moisture had been hidden by precum stains.
“Up,” she barked, that commanding tone of voice returning. Bonbon obeyed unquestioningly, her body moving on its own. It knew exactly what was coming up next, even if her lust fogged mind was having trouble keeping up.
Bonbon dimly registered Lyra's horn lighting up and magically discarding her olive green shorts along with whatever she might have been wearing underneath. There was no ceremony to the action, but Bonbon hardly blamed her for being in a rush to get to the good part. The two mares circled around each other wordlessly, swapping positions relative to the bed. Lyra bent over the bed as best she was capable, given her enormous tits. She had to arc her back significantly, and even then the fat milksacks were squashed and smooshed and deformed by her arms and the bed. Bonbon could just make out a pair of wet stains spreading rapidly across the bedsheets.
A sweet, creamy scent gently wafted through the room, lurking just underneath the nearly overpowering musk of Bonbon's virility. It was surprising that she could make it out at all through the thick odour of cum. But it was there, undeniably. Sweet and rich and heady, sending Bonbon's mind swimming with lust as though it weren't already drowning. With a quiet moan, her cock twitched and let out another few copious spurts of precum, leaving a white streak across Lyra's cutie mark.
“Hey!” Lyra snapped. “Precum or no, try to save some of that for inside me.” She punctuated her complaint by lifting her tail, up and to the side to give easier access to her drooling cunny.
Bonbon dimly realized that she hadn't really paid much attention to Lyra's ass yet. It was understandable, really. Certainly, it wasn't a bad ass. Each cheek was perfectly formed, round and firm and big, pressing together just tightly enough that Bonbon could still see Lyra's eagerly awaiting pussy. On anypony else it would have been just fine. Exceptional, even. But on Lyra it had to compete with those tits, and there was simply no way that any ass would stand up to those.
Still, it was a good ass, overshadowed by tit or otherwise. Bonbon took a few unsteady steps forward, shaking hands firmly grasping each cheek as she pressed her meat into the cleft between them. She bit her lip slightly as she squeezed them around her shaft, her fingers sinking into the pliable flesh. “Oh fuck,” she squeaked as her cock let out yet another eruption of pre. Her hips lurched back of their own accord before thrusting forward, rubbing her shaft between Lyra's cheeks and against her hot, moist box. Lyra's arousal lubricated the length of Bonbon's cock, and likewise the remains of Bonbon's copious precum were thoroughly smeared in between Lyra's fat asscheeks.
“Shit, Bons, stop teasing and put it iiiiinnnnnn~” Lyra moaned, rocking and grinding her hips against Bonbon's own thrusting. “Fuck me, Bons, please, I need it so fucking bad. Put your big fat cock in my tight pussy and fuck me for the love of Celestia! Fuck me so hard my mind shatters into a million pieces, pump me so full of your cum I end up spherical, I don't care what happens so long as you fuuuuuuuuuuuckkkkk!” Lyra's lustful tirade was cut short as Bonbon grabbed Lyra's left leg and hefted it up and out. Her hips pulled back, farther and farther until, with no ceremony or warning, she plunged forward and buried herself in Lyra's eagerly awaiting depths.
Lyra was surprisingly tight. It made sense, really, that Bonbon wasn't initially able to fit the full three and a half feet of her cock inside. It was impressive that more than a foot made it in with that initial thrust. Lyra's mouth hung open in a wordless scream as Bonbon paused, just for a moment to take it all in. Her body felt hot, teetering on the edge of orgasm. Her thick horsecock pulsed rhythmically inside Lyra's tight inner tunnel, pumping her full of copious precum. She lifted Lyra's leg slightly higher, spreading her wider as her other hand began to explore. She wandered down, grabbing at Lyra's ass. Slender fingers sunk into supple flesh, drawing a low, gurgling moan from Lyra. Her cunt convulsed as best it was capable of given how stuffed it was.
Bonbon couldn't help but smirk slightly, giving Lyra's ass a smack before moving on, slowly dragging her hand up to Lyra's belly. It bulged slightly, between the sheer volume of precum Bonbon was producing and the near-airtight seal her giant fucking cock had produced. She could feel it slowly swelling beneath her hand, pulsing just slightly bigger in time with her cock. Her smirk widened into a full on grin as she moved her hand up one last time towards the real prize. Finally, after weeks of fantasizing, Bonbon could finally touch Lyra's tits. Not just indirectly, like the titfuck, not just accidentally brush against them while passing in the hallway, not gently helping her through tight doorways, no clothing or social conventions standing in her way of going fucking wild.
She felt her hand slowly sinking into expansive flesh. Soft and warm and pliable, like an enormous ball of bread dough in desperate need of a good kneading. She pressed in further, squeezing and groping at the tiny fraction of breastflesh she could manage with one hand occupied.
“Oh fuck Bons I'm gonna- I'm gonnaaaahnnnnnn~” Lyra didn't manage to finish her thought, but it was clear what she was going to say – her fat nipples twitched once, twice, and then erupted. Twin geysers of creamy milk sprayed, with enough raw volume to rival Bonbon's cum.
And more than that, Bonbon suddenly found her hand rocketed away from the breast she'd been groping as it suddenly went taut. “What the fuck?” Bonbon managed to force out through the effort of holding back her own orgasm. Lyra was understandably unable to answer the question, but she didn't particularly need to answer. In rhythm with the convulsions of her orgasm, her breasts pulsed bigger. Slowly, but inexorably, the hefty spheres lurched their way outwards, bigger and heavier and, yes, somehow milkier. In spite of the insane amounts of fluid they were unleashing without even any stimulation from Bonbon, the flow only seemed to build on itself as Lyra's breasts quickly reached sizes that would likely leave her immobile were walking something she needed to worry about.
Bonbon didn't really know what was going on. Quite frankly, she didn't care. She'd spent a lot of time today teetering on the edge, and the way Lyra squirmed and writhed and fucking grew was just the thing she needed to finally push her over. The time for precum had passed – pendulous balls pulled tightly against Bonbon's body, the base of her cock swelling with a gargantuan payload. “Fuuuuuuuuuuck!” she managed to cry before erupting in earnest.
Lyra had long since passed the point of being incapable of coherent thought, and then rocketed further beyond, circling around to a sort of clarity. The metaphorical eye of the storm. Articulating sentences was still beyond her, but she could feel everything. Even Bonbon's slightest movement felt like it lasted for an eternity. And Bonbon's movements were hardly slight at this point – wild, frenzied thrusting, churning her immense output into a bubbly froth that spurted out of Lyra's cunt with every movement Bonbon's hips made. Oh, Celestia, there was so much. Even with all the excess that was being forced from her body, she could feel herself beginning to swell. Like someone had tied a water balloon to a faucet and then turned it up as high as it'd fucking go.
It was more than enough to push Lyra higher. Every thrust from Bonbon was another orgasm from Lyra, and every orgasm was another few cup sizes and another few hundred gallons of thick, creamy milk. Another side effect of that glandular disorder – arousal made them produce milk faster. That was, she supposed, something she should have laid on the table on day one, but she hadn't really expected it to become quite so relevant quite so quickly. Something else they'd have to have a more formal discussion about, she supposed, once they finished with their fun.
Though that was likely not going to be for a good long while. Lyra had no idea when they'd started, and was far too out of it to process whether or not there was any kind of clock in the room, much less what time it was by the time Bonbon started to slow down. It felt like they'd been going for longer than Nightmare Moon had been imprisoned times ten, and she was only just starting to slow down.
“Oh fuck.”
“You're tellin' me,” Lyra muttered, taking a moment to catch her breath. “That was... That was somethin'. Hoo boy was that somethin'. You cooled down enough to talk, Bons?”
“Oh fuuuuuck.”
“Bons?”
“Oh fuck oh fuck oh fuuuuuuuuck Lyra I'm cumingggggggggg!”
“wait then what the fuck was thaaaaaaaaaaahnggggggg~” Lyra's thought was cut off as Bonbon's thrusting once again picked up in speed. Faster and faster and deeper, pushing the remaining foot and a half of cock into Lyra's eager hole inch after inch after agonizing inch. To the hilt, if only for a moment before her instinctual thrusting pulled her right back out again. In and out, in and out, over and over. Pendulous balls, pulsing and throbbing and audibly, smacked heavily against Lyra's taut belly to the rhythm of Bonbon's thrusting.
Lyra's taut belly that was getting noticeably tauter as more precum got pumped into her womb. She couldn't see it over the beanbags on her chest, but she could feel it pressing into them as it very nearly outpaced their growth. And it felt enormous. Like she was nine months pregnant with fuckin' octuplets. And this was nothing compared to what was coming – she could feel Bonbon's cock once again swelling at the base, stretching her well-used hole even further. Celestia, it was already huge, and yet it at least doubled in thickness as a gigantic bulge of thick baby batter travelled its way up the enormous shaft, agonizingly slowly. An inch at a time, crawling its way up in irregular spurts, stretching Lyra's insides in ways she'd never before thought possible.
“Cuuuuuminggggggg~”
“Yeah,” Lyra grunted, forcing the words out through clenched teeth and her own orgasm. “I noticed.”
Even as the words left her mouth, Lyra realized her mistake. The base of Bonbon's shaft, already distended with her current load, practically lurched thicker as she came again without having the courtesy to finish her last orgasm first. The second bulge was accompanied by a loud, gurgling groan. Like a rumbling stomach, though Lyra was fairly sure that the source was a bit further south. Big, fat, fertile nuts smacking heavily against her with a loud, rhythmic thwap, thwap, THWAP. Louder, more heavily, and smacking against a much wider surface area as they eagerly went into overdrive, churning and filling and growing with the next few copious loads.
“More,” Bonbon moaned idly as she climaxed again, almost incidentally. Though “climax” wasn't really the right word for it – her orgasms weren't so much peaks as they were stepping stones on the path to higher and higher plateaus of pleasure. No refractory period necessary. “More more moooooreeeeeeeee~” Another orgasm, another level higher and higher and higher. Sex, it turns out, was very much something that Bonbon enjoyed a lot. Lyra was so tight, and only seemed to be getting tighter with each passing orgasm. Her grip faltered, letting Lyra's leg fall as she collapsed forward. She bounced slightly on first impact, before settling down into her new position lying on top of Lyra's back. Her own fat tits pressed firmly against Lyra's slender frame.
Though calling it slender at this point was a bit ridiculous. Lyra's tits alone were bigger than her body, and factoring in her still swelling belly it was enough to lift Bonbon off the ground entirely. Lyra rolled forward slightly, leaving the two mares roughly horizontal. Bonbon's hips continued to thrust, pumping more and more baby batter into Lyra's hungry cunt. Their pace had once again started to wane, though it was barely noticeable even discounting that Lyra's mind had once again been pushed to that point of twisted lucidity. It felt like the world was moving in slow motion, seconds feeling like minutes and minutes feeling like hours. And it was almost certainly at least a further hour before Bonbon finally came to a stop.
“Holy shit.”
“Yeah, uh,” Bonbon blushed slightly. “I, uh, got a little carried away.”
“No fucking kidding. I think your bed mighta gotten squished at some point.”
Bonbon was no longer merely slightly blushing. “This is all a bit new for me.”
“Don't worry, babe. 's new for me too.” Lyra rocked slightly in what was presumably a futile effort to get up, only to be thwarted by her swollen body. “Hey, you think you could just sorta, like... Get offa me for a second? Like, basking in the afterglow is fine and all but I kinda need to drain enough that I can, you know. Move. We've still got shopping to do.”
“Uh, hold on a sec. It's a bit precarious...” Bonbon wriggled on top of Lyra, which caused a significant amount of sloshing from the mint green pony's overfilled body. “Um... Okay I think I might be stuck.”
“Stuck?”
“Yeah. I think I got too big and, uh. I might be a bit jammed in there.”
“Okay, well. New plan. We lie here for a bit and wait for you to calm down enough to pull out and then we drain me.” Lyra sighed. “Man,” she muttered. “I hope this didn't take. It's kinda dangerously close to that time 'a the month and you kinda came a lot.”
“We'll probably be here a while, then,” Bonbon replied, the implications of what Lyra had said flying squarely over her head – perhaps she hadn't heard, or just was confident that it wouldn't be an issue. Regardless, she was probably right. She was still rock hard, and Lyra could feel it throbbing inside her, pulsing slightly with the dregs of orgasm along with relatively small spurts of fresh pre as it prepared for round three. “I usually take a while to come down after finishing normally, and that's without somepony else, um. Stimulating things.”
“I'm not doing it on purpose! Dangit, I had stuff I wanted to do today, too...”
“Can any of it wait?” Bonbon said, her voice slow and careful. “Also try not to move or things could get, you know, dangerous.”
“Actually, you know what, there's one thing I can do here.”
“Oh?”
“Yeah. I was gonna try and do this in more of a romantic way, but what do you say to getting married?”
Bonbon's heart skipped several beats. “I'm- I'm sorry?”
“Yeah, uh, the ring's probably down there somewhere. I've kinda lost track of my pants and it was in my pocket.”
“Oh. Um. Oh.” Bonbon struggled to find words to respond to Lyra's abrupt proposal. Her heart, in an apparent effort to make up for those skipped beats, decided to double the rate at which it was pumping the blood that rushed to her cheeks. And to certain other places.
“Hey, relax, Bons. No pressure or anything, you don't need to make a decision one way or another any time soon and I'm totally cool if you decide marrying's not for you. I just figured that, you know, we get along pretty well and we're gonna be living together anyway, we might as well try and get some tax breaks out of it, y'know? And, uh, recent events have kinda reinforced that decision.” Bonbon didn't respond beyond a small squeaking moan, followed by very heavy and irregular breathing. “Uh, hey Bons, you okay?”
“Yes! I mean no! I mean, um.” It was just a simple question, but hearing it had somehow set Bonbon off. Her whole body felt like it was on fire, and her balls had definitely started growing again. She couldn't see them, but she knew that sensation all too well, hanging down almost to her knees, so big and full and heavy and getting bigger and fuller and heavier and more more more more and- “What was the question, again?” Bonbon managed through the vague haze that had once again descended over her mind.
“Uh... Will you marry me?”
“Oh fffffuuuuuuuck yesssssssss!”
