An Explosive Combination

You blinked awake gently as the dull orange light of dawn streaked in through the window blinds. The sound of you eyelids must have woken up your twin sister, Apogee, laying next to you, because she blinked awake a few seconds later. Maybe she was just watching you sleep and waiting for you to wake up. You laid there, nude, and looked at her just as nude as you were, and she looked back at you. You laid there together in the bliss of the bed you shared with your most wonderful of pillows.

Last night you had sex so hard that you must have died.
That's the only explanation for waking up in heaven.

Your pillows shifted as your mother, Delta, sighed in her sleep, just as naked as you were. You lifted your cheek off of her soft breast and Apogee also sat up in silent synchronization, carefully getting out of bed to let her sleep. You pulled the sheet up to tuck her in while Apogee gathered your clothes off the floor. You followed her out of the bedroom an closed the door.

Inclined to keep quiet, Apogee didn't run a shower. Not that you had time to, anyway. You had both forgotten to set an alarm. You stood at the kitchen sink to wash the essentials while Apogee used the one in the bathroom for a 'bird bath', as your mother had called it, "Pits and pussies."

You both bathed and dressed in silence, grabbing a couple of cold toaster pastry packages to eat on the way to school.

~

It was... strange. Apogee was usually a chatterbox on the flight to school. But not today. It was awkward. Not that things were awkward between the two of you. You were closer than you had ever been. But the entire weekend felt like one big dream. That morning felt like a prolonged waking, when you could still remember your dream. But once you were out of the trailer, it felt like a stark bucket of ice water, returning you to the harsh reality of the real world.

It had been the best weekend of your life.

And now you had to pretend that it never even happened.

Landing in front of the school stairs, it was strange. Despite the bustle of the other students walking in around you, everything felt far away. Colors and sounds felt muted. The only thing that seemed real was your sister next to you as you walked inside. You wanted so much to hold her hand, but you forced yourself not to.

Her finger lightly grazed yours and she briefly caught your eyes before she turned down the other hallway to go to her class, and you went in the other direction towards yours.

Time in class felt like it dragged by until the bell rang. You looked down at the notes you had scribbled and didn't even remember writing them. You auto-piloted your way through the hallway to your locker. You stared at it for a full minute trying to remember your combination before you remembered that you had a key lock and the key was in your pocket.

About half-way through a class you had a brief moment of clarity from your otherwise fugue-state. It was already fourth period, and you couldn't even remember how you got there.

You stalled out in the hallway next to the water fountain, trying to remember what you next class was. No, wait, it was lunch time now. You tried to remember where the cafeteria was, despite going to that school for four years.

Downstairs.

End of the west hall.

"Right." The sound of your own voice startled you. Was it the first thing you had even said out loud that day? Seemed so. You walked to the cafeteria.

"Hey." The stallion walking next to you lightly should-bumped you to get your attention. You looked over at him. You recognized his face. Your friend, Sharp Wit. His familiarity pierced your haze and you found yourself again.

"Hey," you replied.

"You okay?" he asked.

"Yeah," you answered reflexively.

"Really!? Because you were out Friday, and we didn't hear from you all weekend. And after everything with Rose, we were worried that you... you know..." He pantomimed a gun with his fingers to his temple.

"What? No! I'm fine," you assured him.

"Really? Because you look..." He waved his hand in front of his face.

"No, I'm fine, really," you said. The memory of waking up next to Apogee flittered across your mind. You couldn't keep the smile from the corner of your mouth. "I'm good."

Sharp's expression shifted from concern to curiosity. "Oh? Then where were you all weekend? I sent you like five texts."

"Sorry. I was just busy," you explained.

"Doing what?" he asked.

You recalled visions of your mother riding your dick like it owed her money. You felt your cheeks get warm with a blush you couldn't hide. You shifted your book bag to cover the bulge in your shorts.

Sharp could read you like a book and smirked. "Dude! Did you get some!?"

"No!" you blurted. "I mean, what!?" Your face went from pink to red.

"Oh, shit! I know that face! You GOT some didn't you!?"

"No!"

"Dude, why are you even embarrassed!? You should be proud! Shit, I've always said that the best way to get over somebody is to get under somebody else."

"For fuck's sake, Sharp, lower your voice!" you said as you neared the cafeteria.

"Okay, but dude, you gotta tell me who it is."

"No, I do not! I mean I would not, if I did do that. Which I didn't!"

"Dude, you suck at lying," he said as you each grabbed a cafeteria tray.

"I'm well aware."

"You obviously did it. Come on, I thought I was your best friend."

"I know."

"So?" he asked as you each shoveled some... food onto your plates.

Your eyes briefly glanced across the cafeteria at the table with the yellow freckled filly. "Can you keep a secret?" you asked in a hushed tone.

"Yeah."

"So can I!" you said without another word.

"Come on! If I did it, I would tell you who it was," he said as you carried your trays to your usual table.

"Yeah, and then you would tell everyone else!"

"Tell everyone else what?" your other friend, Emerald Wings asked as you sat down at the table with Apple Core and Pixel Dust, who also looked curious.

"Aileron got some last weekend!" Sharp announced to the table.

You slammed the table with your fist, making the silverware rattle. "This is what I'm fucking talking about!"

After school, you were halfway home before Apogee even said her first words to you that day.

"So... I heard you got laid last weekend," she said.

You rolled your eyes. "You know I did."

"Yeah, but I heard that you did."

"From who?"

"From everyone!"

The laws of physics forbid anything from going faster than the speed of light. But a high school rumor could surely give it a run for its money. And the harder you tried to deny it, the faster it spread. That was just how rumors worked.

"Who did you tell!?" she asked.

"I didn't tell anyone. Sharp just assumed I did just because I didn't kill myself... Because I wasn't still broken up about Rose."

Apogee snorted. "Forget broken up! You were practically glowing all morning."

"What?"

"Have you not looked in a mirror? You had this dumb smile on your face all morning like you had Peyote for breakfast." You snorted, but Apogee's face showed her concern. "Does he know... who?"

"What!? No! NO! No-no-no! I would never ever!" Your vision sharpened and narrowed with a rush of adrenaline. "No! To the grave, THAT does not leave the trailer!"

Apogee nodded. Her expression remained neutral, but at least she didn't look worried anymore. "Well, speaking of..." The outline of the junkyard grew closer as you flew towards it. "What do you think she is going to say?" she asked.

You glided down to the driveway. "We're going to find out soon enough..."

~

You sheepishly pulled open the trailer door and slowly lead the way inside with your schoolbag at the ready as a shield. Apogee followed in behind you.

On the kitchen table there was a note with bold lettering.

Went out.
Back late.
On your own for dinner.

"Where do you think she went?" you asked as you set your bag down.

Apogee shrugged. "The bar?" You wanted to object, but in light of recent events, that would have been a perfectly reasonable guess for anyone, not just Delta. So you just nodded. "I guess that means we have time," she said.

"Yeah," you agreed. "We ought to think about what we're going to say."

"I meant more like, we have time for one last romp," she said as she started peeling off her school uniform.

"What? Get one last use out of my dick before she cuts it off?" you asked.

"Ha!" Apogee scoffed. "I told you she would never do that. She enjoys it too much! And besides, if she was going to, she would have done it last night while you were sleeping."

"That doesn't make me feel better," you groused as you stepped out of your shorts.

Apogee threw off her top and bent over to pull down her panties. "I meant one last time before she sends me packing back to Dad's place, and keeps you to herself here for the rest of the summer."

"You don't really think she would do that, do you?" you asked, stripping down to your underwear.

She shrugged. "Maybe not. But either way, I'm not passing up this opportunity, are you?"

The tent in your underwear had already cast your vote. "No, obviously not." You pulled down the elastic waistband, letting your erection spring free.

She hopped across the floor to give you a naked hug and kiss you. You kissed her back and picked her up with your hug before setting her butt down on the table. You kissed her again on the lips and then worked your way down to her pert nipples. After giving each one plenty of attention you kissed your way lower down her toned abdomen.

"I had gym today," she whispered.

You could already tell as you lowered your head down between her legs. She laid back on the table and relaxed as you went to work savoring her heavy aroma. Her head leaned back off the other edge of the table as you worked your tongue inside her and then up to flick her clitoris. You held her thighs with your arms, letting your mouth do all the work, licking, kissing and sucking.

"I'm already so close, Aily! I was thinking about this all day," she breathed.

You briefly came up for air, "Me too."

She moaned as her hand gripped your mane. Her thighs squeezed your head as you felt a warm trickle running down your chin. "F-fuck!" she hissed.

"... You know, when I said you were on your own for dinner, this isn't what I meant."

Apogee looked back, upside down, and your head popped up from between her legs to see Delta standing in the trailer doorway.

"Mom!?" you both yelped. You both scrambled to make yourselves decent.

"Oh, you don't need to stop on my account," Delta said casually as she walked inside.

"We thought you were out," you said.

"I was," Delta said. "I was waiting in the hangar for you to get home, and see what would happen." You both looked away in shame. "I honestly don't know what I was expecting, but I suppose I shouldn't be surprised at this point."

"You said you weren't going to be home until late," Apogee said as she climbed off the table to sit naked beside you in the dining booth.

"That was obviously a lie," Delta deadpanned. "So the lesson is that, 'lies and secrets lead to unpleasant surprises', isn't it?"

"Yeah," you and Apogee answered.

"So Rule Number Two is cards on the table. No more lying or secrets between the three of us anymore!" Delta said.

"Wait, what's Rule Number One?" Apogee asked.

"This shit does NOT leave the trailer. EVER!" Delta said. "Especially your father!"

"Well, yeah, that goes without saying," you said.

"No, it most definitely goes WITH saying!" Delta snapped. "This is why I wanted to talk to you two knuckleheads this morning before you went off to school. None of that cutesy hand-holding, playing footsies bullshit, stealing quick kisses when you think nobody is looking. And definitely no fucking in the janitor's closet!"

"We didn't!" Apogee said.

"The janitor's closet..." you mumbled with a goofy smile.

"Don't!" Delta yelled.

"Hey, I didn't even think of doing that until you mentioned it!"

"Don't do it!" Delta yelled louder. "You will get caught! And then you'll get taken away by the state and separated to different foster families and I'll probably end up in jail!"

"Mom, the state can't take us away!" Apogee said. "We're both adults."

"Then you'd be getting a public exposure charges plus... you know, the 'I' word." Delta cringed. "Just keep that shit in your pants until you graduate!"

"... Unless we're in here?" Apogee added.

"As long as you sure as shit are on your Moon Tea! That's Rule Three!" Delta said.

"Of course!" Apogee said. "I'm horny, not stupid!"

"There is a LOT of fucking overlap between the two! And the last thing we need is a pregnancy!" Delta huffed and crossed her arms. "But so long as you do that, then yeah, I guess it's whatever!"

"Are you mad?" you asked.

"No. Why should I be? Why should I even be surprised?" Delta said. "I told you both you needed to be doing this with someone your own age. I knew Apogee's little curiosity phase would end. And as for you... Well, you've obviously traded up to a newer model."

"What? No!" you said, standing up. "Mom, it's not like that!"

"Yeah, it's not a phase, Mom!" Apogee said. "This is who I am!"

"Aaand, we both still love you!" you assured her. "I mean, yeah, I love Apogee too, but there's no replacing you! I mean come on, look at these!" You walked around behind her and hugged her, squeezing her huge breasts and grinding against her butt. "And nothing against Apogee, but she still has a long way to go to compete with the Throat G.O.A.T."

Delta pursed her lips. "I don't think that's the compliment you think it is!"

"He's not the only one who loves your boobs," Apogee said, joining the grope-hug to grab a handful, herself. "And while we're being honest, Aily, there's a few things she could teach you about going down on a mare. And you know I'll return the favor, Mom." Apogee winked.

"We both do," you added, kissing the back of Delta's neck and sliding your hands up under her shirt. You cupped her breasts with your hands and lightly teased her nipples. Apogee knelt down in front of Delta and pulled down her shorts. She gave Delta's crotch a little lick, kissing her clitoris as she reached between her legs to grab your dick and feed it between them. Apogee kissed your dick and licked Delta's pussy as you made little thrusts against it. Delta started to pant and moan, struggling to even stay on her feet, but you held her steady in your hug.

You shifted your hips downward and angled your thrust upwards with Apogee's help to aim you. Apogee's tongue already had you and Delta plenty wet, letting you pop inside with minimal resistance. A few small thrusts and your balls were bumping against Apogee's chin as she alternated between licking your shaft, sliding in and out, and sucking Delta's winking clit.

You felt your mother put her hand on your hip. Not to push you away or to pull you into her harder. But just to touch you as you continued gently thrust inside of her. Looking over her shoulder, you could see her other hand running through Apogee's mane. Again, not to shove her away, or gripping it to aggressively pull her into her crotch. Just running her fingers through it, intimately as she kept licking.

Delta's body trembled. You recognized her orgasm. You could feel it in her muscles, rippling around your dick, and dripping out of her onto your balls. She took a sharp breath. You expected an expletive or some variation of 'I'm cumming', which was always a sure way to get you off just as soon as she did. But the words she spoke caught you off guard.

"I love you," she said.

You weren't sure to whom she was saying it. Presumably both of you. You didn't think that there was a more surefire expression she could say that would get you off any faster than 'I'm cumming', but sure enough you could feel yourself flaring inside her. Her throaty moan was indication enough that she could feel it as well. Apogee's warm hand cupped your balls as they tightened and she kissed your shaft as it twitched and throbbed with each pulse, pumping your thick load deep up inside your mother's vagina.

She filled surprisingly fast, producing quite a bit of back-pressure, forcing your cum out around your flare. Apogee was only too happy to lick it as it dribbled down your shaft. The pressure built until it pushed you out with a wet 'plop'. You expected a splatter of cum to hit the floor between your feet, but the only sound was Apogee lewdly slurping your cum out of Delta's pussy like the last bits of a milkshake.

Delta's knees wobbled and she fell into your arms. You held her steady and helped her to the bedroom where she could sit on the mattress. Apogee sat down on the other side of her and lifted off her shirt before leaning over to suck on her nipple. You did the same on the other side as Delta laid back in the bed, hugging you both close, gently running her fingers through your manes as you suckled, looking up at her with loving eyes, and seeing her return them.

Last night you had sex so hard that you must have died.
That's the only explanation for waking up in heaven.
