An Explosive Combination

Tuesday and Wednesday felt like being stuck in a time loop, with each of your classes getting ready for your final exams, and you refusing to divulge the details of your previous weekend. With no new information for gossip, the rumors about you faded as quickly as they had started. The short attention span of the student body was the best and worst thing about high school.

Everyone else around you was stressing over finals. To you, it was about as stressful as waiting for a punctual bus. You knew it was coming and you were prepared for it. And now you were just running down the clock. Your twin sister, Apogee, was in the same boat. Aside from her, your friend Pixel Dust was the only other student not worried.

"Honestly, I'm more worried about graduating," Emerald Wings said at the lunch table.

"What do you mean?" you asked. "Graduating means it's over."

"Exactly!" Apple Core said. "It means we'll all be leaving and going off to different schools. Emerald is going to Cloudsdale Community College with Sharp Wit, and you're going to Las Pegasus University with Pixel Dust. But I'm the only one going to Ponyville Vocational. How are we going to stay in touch?"

Pixel tapped her phone with her finger.

"That's not the same," Sharp said.

Ms. Whirlpool walked by on cafeteria chaperone duty. "Why the long faces? You're graduating on Friday! You're not worried about finals are you?"

"No, its just that we're going off to different schools after this," Apple Core said. "How did you keep in touch with your friends after high school?"

"Ah. That is a toughie." Ms. Whirlpool nodded. "The truth is, I could count all the people I've stayed in touch with from high school on one hand. And even then, it's only a few times a year. People grow up and move on and move away. They start new jobs and new families. Life changes. All the time. And the people who look back at high school as the best years of their life are the saddest people I know. Now is not the time for your life to peak. Yeah, you leave behind some friends along the way, but you make new ones, too."

"That's not very reassuring," Emerald said.

Ms. Whirlpool smiled. "Moving on doesn't mean you have to leave your memories behind. I still have a lot of great memories from high school. And that's something that will last a lifetime... I hope that helps."

"Thanks," Apple said before Ms. Whirlpool continued her patrol.

Sharp looked around the table. "I'm not ready to say goodbye yet. But I will say that it has been fun knowing you all."

Wednesday night was the first time it really felt like a school night that week. You and Apogee sat in the trailer at the kitchenette table and actually studied.

"Hey, check out what I found!" your mother, Delta Vee said, walking out of her bedroom. "I was going through my old things and I found this!" She turned in place, showing off her old high school cheerleader outfit for the Cloudsdale Drafts and pompoms.

You loved your mother. Really, you did. But you found yourself at a loss as to how she ever managed to get herself into that uniform. Her maternity pudge, which you found delightfully squeezable, looked uncomfortably squeezed out above the hem of the skit, and below the short midriff cut of the top, which itself, was straining to contain her heaving melons. Quite in fact, you could see a decent percentage of her areolas spilling out of the top.

"I can't believe you were ever a cheer leader," Apogee said.

"Honestly, no, I wasn't," Delta admitted. "This actually belonged to an old fillyfriend of mine. She used to wear it sometimes when she came over and we'd-"

"Yeah, we get it," you said. "You'd do lesbian stuff. That's very hot and I'd love to hear about it after finals, okay? We're trying to study."

"I'll give you something to study," Delta teased, trying to stuff her breasts back inside the thin fabric of the top. She picked up her pompoms again. "Ready Drafts? Let's go! Give me a D!" She made a small jump, causing the shirt to finally tear, letting her tits spill out completely.

"Mom, that's not fair!" you said, physically covering your eyes with your hands. "It would take so precious little to pull me away from this, and your boobs are weapons-grade distraction!"

Apogee looked back over her shoulder at your mother's state. "Those make me horny, also," she said before she went back to studying her flash cards.

"Well fine! If you're both going to be like that, then I'll be in my bedroom! Masturbating! Alone!" Delta said before storming into her bedroom.

"Why is Mom being so... extra tonight?" Apogee asked.

You shrugged. "I guess she's even more excited about the summer break than we are."

"Did you call Dad about that?" she asked.

"Yeah. He didn't answer. I left him a message. We can get it sorted out Friday."

"Do you think he'll agree to it?" she asked.

You shrugged. "I don't see why he wouldn't. It's probably more the case he won't believe that Mom wants to go with it. Then it'd just be whether he wants to pay to have our stuff moved or have us take a bunch of trips. Either way, it's not like he can stop us. We're both adults."

"True."

"..."

"..."

"So are we sleeping out here tonight, or..?"

On Thursday, you found the finals were mildly challenging. After lunch was graduation gown fittings. You waited in line with your friend, Sharp Wit. His phone chirped and he checked his notification.

"Huh. Looks like Rose is single again," he said to you as he read it. "Apparently her new guy heard the rumor about you getting lucky and assumed it was her with you." He looked at you. "Was it her?"

You couldn't help but chuckle as you shrugged. "Yeah, sure."

All that was required of Friday graduation was to just show up.

Standing next to you in her graduation gown, Apogee squinted up at the stadium seats. "I found Dad," she said, pointing at the stallion up in the back of the nosebleed section.

"Mom's over there," you said, spotting your mother on the other side of the field. The two ponies could not be further apart while still being inside the same stadium.

The graduating students were called up in alphabetical order. Both you and Apogee received your diplomas early on with the rest of the A's.

Delta walked down to meet you at the edge of the field. "Congratulations. Does this mean we can get out of here now, before-? Ugh, fuck."

Your father, Jet Stream, drifted down from his glide over the field. "Congratulations," he greeted curtly before taking his phone from his pocket, pulling up the text you had sent regarding moving in with Delta. "Is this real or this one of those may-may pranks your generation likes to pull?"

"No, it's real," you said.

He looked at Apogee. "Both of you?" He asked. Apogee nodded. He met Delta's eyes. "And you're okay with all this?"

"Yes," Delta answered simply.

Jet just chuckled and put his phone back in his pocket. "I never thought I'd see the day... They must be opening a ski resort in Tartarus right now."

Delta remained calm. "Do they need to move their stuff themselves or-"

Jet put his hands up. "No. Not at all! I'll have some movers bring everything over first thing tomorrow." He looked at you. "Shipped First class. Everything will be insured against damage."

"Thanks," you said.

"Well if that's it, then..." He turned to leave but turned back at the last moment. "There is just one thing though, Apogee, Aileron... You better be sure about this. Because I'm not going to just leave those penthouse bedrooms empty. So if you change your mind a month from now, you might not have a bedroom to come back to. Are we clear?"

Your nostrils flared but you kept yourself in check. "Crystal."

"Yeah," Apogee agreed.

Jet nodded. "Okay..." He looked at Delta. "They're all yours." He turned and walked away to fly home.

"..."

"This is a good thing, right?" Apogee asked.

"Yes," Delta said.

"Then why do I feel angry?" you asked.

"Because he thinks he's getting the better deal out of all this," Apogee said.

"Fuck him!" Delta said.

"Uh..." Apogee gave her a weird look.

"No, I don't mean actually fuck him, dipshit! I mean forget about him! Let him think he's won. He doesn't have what we have."

"Yeah!" Apogee cheered.

"Come on," Delta said. "Let's go home."

That actually made you smile.

The three of you flew back to Delta's trailer.

No.

The three of you flew home.

"Ugh! Too many layers! I can't wait to change out of this!" you said, pulling your gown off as soon as you landed in the junkyard. Apogee land behind you and darted past you to go inside before pulling her gown off too. "You were nude under your gown!?"

"So what? You're nude under your clothes," she said.

"Well I'm glad I didn't know that this morning," you said. "I didn't need to be getting my diploma while following a divining rod!" She stuck out her tongue at you as Delta walked in with the mail, barely giving her nude daughter a second glance.

"Anything good?" you asked.

She flipped through the stack. "Hmm, junk, junk, bill, junk... someone wants to make my horn twenty percent bigger... junk... oh... oh fuck!"

"What? What is it?" you asked, as you and Apogee rushed over to look at the envelope. The return address was marked C.C.C.P. "Oh shit! That's- that's the contract bid thing!"

Delta almost fell into her chair. Her hands were shaking so bad she could barely open it. "Please," she begged as tears streamed down her cheeks. "Please!" She caught her fingernail under the tab and pulled it open. She pulled out the tri-folded letter. She blinked rapidly trying to clear her vision.

"Mom, here," you gave her the reading glasses that she hated. But she didn't object to wearing them now as her eyes scanned the page.

Apogee double checked the envelope, pulling out a small slip of paper. "Oh, it's a check. Well hey, even if you didn't win, you still got seven hundred fifty bits."

"Apogee, that's not a decimal, that's a comma," Delta said.

"Oh?" Apogee looked at the check again. "Oh! Oh my gosh!"

"I got the contract!" Your mom nearly did a fucking backflip as she jumped out of her chair. "I GOT THE CONTRACT!" She yelled and screamed and jumped up and down, and then stopped suddenly. "Ow, I think I pulled a tit!"

"I got em!" you said, hugging her tightly from behind, firmly cupping her breasts. "Okay, ready." You jumped up and down together while you supported her. It didn't take long for your boner to join in on the grinding fun.

Delta carefully placed the letter and the check on the table and then started rapidly stripping. "Okay. Bedroom. Both of you. Now. We are celebrating!"

Delta flopped onto the mattress. "Okay, first order of business, we are buying a new, bigger bed to share! A bigger trailer! A double-wide! Fuck it, a proper pre-fab!"

You tried to curb her enthusiasm, "Mom, that check isn't going to stretch very far if you-"

She grabbed you by the shoulder to pull you down onto the mattress and climbed on top of you. "Read the letter! That's only the first payment!" she said, grinding her hips on yours. "That's for the design engineers! And the engine has already been designed!"

"Okay, but still-"

"I can write it off as a business expense to house my employees. You'll be my..." She reached under herself to aim your dick up into her as she lowered herself down. "... my staff!" She started riding you slowly and moaning.

"It's my staff you should be worried about!" Apogee said, standing behind Delta wielding a strap-on. The harness went around her waist like a garter belt with a loop around each of her toned thighs, keeping her crotch clear. The clone dildo bobbed in front of her menacingly.

She pushed Delta forward, off of your dick to fall on top of you, smothering you with her breasts. Apogee took her place behind her and mounted her with the strap-on. "Now I'm the Momma!" She gave Delta's butt a modest smack with her hand before she reached under herself and aimed your dick upwards between her legs. Your sister rubbed your dick against her pussy before she finally got it to slide inside, taking about two thirds of it.

Under the weight of the two mares you had no leverage at all to even participate. Apogee was doing most of the work, moving up and down on your dick as she slid in and out of Delta. Apogee shifted into more of a squat to get her weight off your hips. Delta's weight was still pinning down your torso and drowning you with her tits. But at least you could move your hips to thrust upward into Apogee. The angle was a bit awkward to coordinate, with you going up and down and Apogee going back and forth. And you were running out of oxygen.

If Apogee noticed you stop humping, she clearly didn't care. If anything it just made it easier for her to go. You braced yourself and lifted Delta by her shoulders off of you to get a breath of air. Delta did her part to hold herself up. Free from between her cleavage, you could hear again and look up at her. Her face was strained and so was her panting. The room resounded with the smacking of Apogee's hips against hers.

You never considered yourself a gentle lover, but you never fucked your mother especially hard either. Apogee seemed to have no such restraint and she repeatedly moaned, "I'm the Momma... I'm the Momma..."

"Wow, she is fucking you hard!" you said.

"Ngh-Hng!" Delta grunted through her teeth and nodded as her whole body kept rocking from the pounding of the filly that was practically half her size.

Apogee grabbed a fist-fill of Delta's mane and pulled her head back. "I am fucking her really hard! Tell him how hard I'm fucking you!"

"Ngh! She's fucking me so hard!"

You were both confused and incredibly arouse. Questions could come later. You would cum sooner.

Apogee pulled back a bit more, making Delta kneel upright in front of her. Apogee's strap-on inside her was still aimed forward, straining a noticeable bulge in Delta's abdomen. Apogee looked over Delta's shoulder at your shocked face. "I didn't tell you to stop!"

You obliged her, thrusting your hips again up into Apogee, letting your momentum carry through her hips up into Delta. Apogee moved her hand to grab Delta's boob and play with her nipple while the other one reached around and played with her clitoris.

"Are you close?" Apogee asked. Delta nodded. Apogee looked at you, "You better fuck me faster, Aily." You didn't know what kind of clock you were up against, but you knew better than to disappoint a sex-crazed mare armed with a dildo. You gave her all you had. Apogee closed her eyes and grinned. "Almost... almost..." Suddenly her hand was a blur of Delta's clit as she whispered into her ear, "Cum for Mommy!"

Delta's legs shuddered as she squirted fresh wetness dripping down the dildo and splashing off of Apogee's fingers as her moan harmonized with her mothers, soaking your laps as well before they fell forward together, off of your dick and on top of you, knocking the wind out of everyone. As horny as you were, your self preservation instincts were stronger and you shoved, less-than-politely to get out from under them and breathe.

You sat up on the edge of the mattress while the two mares were still in the midst of their toe-curling climax. You moved over to give Apogee room to finally roll off of Delta. The dildo pulled out of her with an audible 'shlorp', and bobbing in front of Apogee menacingly. She sat next to you on the edge of the mattress.

You looked at the rubber dong sprouting from her crotch. Sitting side by side, it was of some relief to you that it was smaller than your dick, in terms of length and girth. If only just a little. Though the dildo had the advantage of never going soft. Not that you were anywhere near soft yet. She looked at you with a maniacal grin.

"I would do anything for love, Gee. But I won't do that!"

"Coward," she teased as she started to undo the buckles. She looked behind her at Delta. "It's your turn to be the Mommy."

Delta rolled over onto her back and groaned. "I need a minute or, like... sixty." Apogee ignored her and lifted one of Delta's legs to start strapping it on her. "Apogee..."

Apogee pulled Delta's butt to the edge of the mattress to get the last strap around her waist. "You're the Mama now!"

Delta just sighed. "Fine, but you're gonna have to be on top. I'm wiped out."

That suited Apogee just fine as she climbed up and squatted over Delta's rubber erection and got right back to it while Delta laid there with an expression somewhere between conceding acceptance and mild annoyance. If Apogee noticed, it clearly didn't bother her. She was too busy looking at you.

"Are you just going to watch?" she asked as she bounced up and down on top of Delta.

You smirked. "It wouldn't be the first time."

Apogee grinned and nodded behind her. "Come on."

You walked behind her and she paused to let you get started. The tip of your dick touched the tight pucker of her anus.

She yelped. "No! Not me! Her!"

"Oh." You aimed it lower between the straps of the harness on Delta's thighs. Your mother was still dripping wet, letting you slide inside her with ease. Apogees bob-tail tickled your belly as she resumed bouncing once you started thrusting. Rather than holding your mom's thighs like you normally would, you reached around Apogee to hug her.

"Hey," she breathed.

"Hey," you whispered back, lightly playing with her pert nipples under your fingers before sliding your hand down into her crotch to play with her clit too.

"Aily..." Apogee moaned.

"Shh... I'm the Daddy now," you said.

"No," Apogee said firmly.

"No!" Delta echoed.

"No, it doesn't work like that," Apogee explained. "Don't do that."

"Why?"

"Just don't."

"Fine! Your lesbian rules are weird."

"Less talking, more fawking."

"Okay that was a bit of a stretch."

"You're telling me," Delta wheezed, putted her hand over the bulge you were making in her belly.

"Me too!" Apogee said. She leaned back against you to and grabbed your hand from her chest to touch the bulge protruding her tummy from the dildo inside her. Meanwhile, her hand joined Delta's on her belly, feeling you inside her. "I want to feel it when you cum inside!"

"You have felt it," you said. "Quite intimately."

"I mean inside her!"

You were about to oblige her, regardless, already teetering on the brink from before. With her hand still on your bulge inside Delta, Apogee twisted in place and looked back at you over her shoulder to kiss you. With how carnal everything had been up to that point, the sudden intimacy of it actually caught you off guard. You felt your balls tighten and your dick flared as she slipped her tongue into your mouth. You kissed your sister back as came deep inside your mother. Your ragged breath came in hot snorts against her cheek. Apogee could feel your dick throb and pulse inside Delta. Like last time, the pressure inside built up quickly, forcing your dick out, followed by a rush of your cum gushing out of her pussy and dripping onto the floor.

...

You stood naked in the kitchenette, leaning against the refrigerator as you chugged a glass of orange juice. Delta walked by you, almost as naked, save for the strap-on leading the way. She opened a cabinet and took out a paper bag.

"I actually did go out on Thursday to get you guys something," She said, pulling out a large bottle.

"Champagne?" You asked.

"Kind of." Delta passed the bottle to you to look at the label. "It's just sparkling grape juice."

You looked at her with surprise. "You're still on the wagon?"

She nodded. "At first it was just inconvenient to run out for more. I kept expecting you to get some. Then it became a challenge for myself to see how long I could go. And then after what you said to me the other night..." She looked away in shame, leaning on the counter. "So yeah, I'm trying."

You smiled. "I'm proud of you."

Her eyes watered. "It's been a long time since anyone has said that to me."

You walked over and hugged her. She turned around to hug you back.

You yelped. "Ow! Can you take that off?"

Delta laughed through her tears and unbuckled the strap-on, letting it fall on the floor to step out of the harness. You hugged her again.

Apogee bounded out of the bedroom. "Oh! What did I miss? Group hug!" She hugged you both.

"Mom quit drinking," you said.

"Really!?"

"I'm trying to," she emphasized. "Don't get too excited. It's been barely a week."

"Mom, I'm so proud of you!" Apogee hugged her harder.

"Guys, come on..." Delta wiped her eyes. "Did I really set the bar that low?"

"We know you can do it!" Apogee said.

"We know how stubborn you are," you said.

Delta scoffed. "You've got that damn right."

You looked at the bottle of sparkling grape juice. "We could have champagne though, Apogee and I."

Delta winced. "I'd rather you didn't. It's not a good habit to start. And I..."

"Better to not even have it around," You said.

"That would be unfair," Apogee agreed.

"We can live with that," you said.

"Thanks," Delta said. She finally wiggled her way out of the hug. "So what does master chef Aileron have in mind to eat for dinner?" You grinned at her. She rolled her eyes. "A growing stallion can not live on just eating pussy." Apogee opened her mouth to speak. Delta cut her off, "Even if it's filled with a protein shake!"

You smiled. "I actually do have a really good meal planned for tonight." You had been the only stallion in a classroom of thirty for Home Economics. That was it's own perk. Actually learning how to cook well was just a fringe benefit.

You cooked a wonderful meal, served on clean plates that weren't made out of paper. You all sat together at the table and ate dinner as a family.

After everything else that had happened, and getting the horny out of your systems earlier, you were all quite exhausted by the time you went to bed to sleep. You laid down next to Delta, nuzzling your cheek against her bare breasts. Apogee cuddled up on the other side of you, pressing her naked body against yours.

"No, come on! I'm not getting sandwiched in the middle again," you complained. "You're both too warm."

"You can come over here," Delta said. You both shifted over to make space on her side of the bed. Apogee laid down behind her and wrapped her arm around, giving her hips a little dry hump.

"It's okay, Mom. At least one of us appreciates your butt!" Apogee teased, reaching across flicking your ear with her finger. Even after everything, she was still your sister.

"Behave," Delta muttered. She was still your mother.
