Argyle can leave little Hitch and Sunny alone for an hour and they won't get into trouble... right?

This is colt / filly foalcon, if that wasn't obvious.

Lessons were learned

"This is sooooo much better without Sprout," Sunny said, moving her figurines on the table.

Hitch nodded. "Pegasi! Make some clouds!" he said, moving the Twilight figurine around.

Sunny giggled, her ribs shifting the cardboard wings.

Hitch looked at her. Something seemed different, lately, and he wasn't sure what.

Argyle hustled in. "Hi dad!" Sunny shouted.

"I just got a call from my doctor," he said. "They want me to rush in for a test. Can you two behave for an hour if I leave you here alone?"

"Sure thing, dad!"

"Of course, Mr. Argyle!"

The two foals nodded.

He looked at them. "You may each have one unicorn cupcake while I'm gone, if you get hungry—"

"Hooray!" they shouted, running to the lift platform and lowering themselves to the kitchen.

They each carried a cupcake to the living room and sat on opposite couches, eating messily and grinning at each other. Argyle rushed out of the lighthouse.

Sunny's face was coated in frosting and she sat on her haunches, licking her hooves. Hitch ate just as messily, but more slowly, half his cupcake remaining.

Something about Sunny... something about... her belly. For the first time, he noticed just how flat her belly was. It had always been flat, but for some reason, he never noticed before. Since she was sitting straight up on the couch, hips wide, he saw how her smooth belly went down, down, down, to her—

And her...filly parts were fluffier than they used to be. Huh. Why would a pony's parts get different as they got older? He didn't understand.

But he felt his own parts getting... different.

Sunny giggled. "You're peeking at me," she said.

Hitch looked down and saw the tip of his ding-a-ling peeking from its hiding place. He gasped and dropped the remaining half of his cupcake. It splattered on the floor.

"Ah!" Hitch screamed at the loss of the dessert.

"Oh... oh no," Sunny said. She hustled to the kitchen and got some towels and a mop. The two of them cleaned up Hitch's mess and, thank hoofness, Hitch's ding-a-ling retreated while they worked.

With the mop put away and the floor clean, they looked at each other.

"You still have cupcake on your face," Sunny said.

"You still have cupcake on your face," Hitch replied, "And I didn't get to eat all of mine." Hitch licked her lip, getting a bit of frosting. It tasted sweeter than the frosting on his own cupcake had tasted, if that was possible.

Sunny blinked, ears stiffening straight up. "Do that again."

Hitch's ding-a-ling was feeling tingly-wingly dongly-wongly again. He licked Sunny's face some more, getting all the crumbs of cupcake frosting off her.

"That... um..." Sunny said. "That makes my peehole all tingly."

"Do you need to pee?" Hitch said. "I can wait here."

Sunny thought for a second. "No. I feel like... I want to get more full? Not like I need to pee? That's weird."

"That's weird." Hitch smacked his lips. Yes, the cupcake crumbs and frosting tasted better off of Sunny's face than off the cupcake itself. That, too, was weird.

Sunny licked Hitch's face and it was wet and sloppy and his instinct was to yell ew filly spit gross but the warmth of her tongue froze him in place and he felt his ears, his tail, and his ding-a-ling all get very stiff.

"Oh, cupcakes are better that way," Sunny giggled, smacking her lips.

Hitch just nodded.

"The last time daddy left me home alone," Sunny said, "Sprout wanted to play doctor. But he just lifted up my tail and I bucked him in the face."

"That's gross!" Hitch said.

Sunny nodded. "But I might like playing doctor with you. Want to play doctor?"

"How do we play that?"

Sunny pranced a circle around Hitch, making her fake wings flex and dance. She stood behind him. "Raise your tail and I'll examine you."

"Okay," Hitch said. His head felt dizzy and his tummy felt flippity-floppity-floopity, but he did what Sunny said, raising his tail high.

"Hee hee... colt parts," she giggled.

"Well-well-well-you have filly parts!" Hitch countered.

"How do you know?"

"You showed them to me when you sat on the couch eating cupcake!"

"Oh," Sunny said. She was silent for a second. "Well, you can be the doctor next."

Hitch held still, his breaths rapid, as Sunny stood behind him. She touched one of his peanuts with her hoof and that made his ding-a-ling even stiffer. Her hoof moved to his other peanut.

"Those are neat," Sunny said. "They're bigger than they used to be."

"What?"

"I've been watching you," she said. "Your colt parts are bigger than they used to be."

"Your filly part is fluffier," Hitch countered.

"Yeah, Daddy said he's going to have to give me 'the talk' soon. I... I don't know what that means." Her hoof slid from his peanuts to the underside of his ding-a-ling and he gasped.

"Hey, you're warm," Sunny observed.

Hitch just nodded.

"Okay, now you be the doctor," Sunny said. She turned around and raised her tail.

Hitch turned and looked at her. Her legs were long and slim and went up to her bottom and her tail stood straight up. He swallowed and his ding-a-ling throbbed underneath him.

Her poopy hole was right under her tail, but he ignored it. Poopy holes were gross and besides, he had one, too, so it was boring. Her filly parts drew all his attention. Soft flaps of skin with a wonderful pink slit between them stood just in front of him and he couldn't look away. Fluffy fur surrounded the filly parts and Hitch rubbed a hoof through the soft fuzz.

Sunny made a tiny sound and her whole body shook. The soft skin, which looked almost like lips that went up-and-down instead of side-to-side, pulsed and her poopy hole jumped, too.

Hitch, before he could stop himself, kissed those lips. Sunny shouted and stomped, then said, "Do that again."

Hitch dragged his tongue along her pinkness and it was wet but it tasted even better than cupcake.

"Eeeeee!" Sunny squealed.

Hitch smacked his lips. Then he looked closer at her filly parts. With one hoof he gently spread the lips apart. There was a pink... something, like a little bit of thin skin, but past that... "Hey, hey Sunny?"

"Y-yeah?"

"I think I can fit right in."

"You're gonna fit right in?"

"Doctors do exams, right? Let me take your temperature."

"Okay!" Sunny shouted.

Hitch hopped up, putting his forehooves on her back and jostling her pegasus wings. His ding-a-ling, with what seemed to be a mind of its own, went straight to her pinkness.

"OOH!" Sunny said.

Hitch pushed forward, his rear hooves scraping on the floor and his ding-a-ling flexed as it pressed against the thin pink covering of her opening, his peanuts hanging low and feeling sore for some reason. He pushed harder and with a pop and a tear he was through and into her. She gasped and yelped and Hitch looked down and saw a tiny little drop of blood where his ding-a-ling entered her filly bits.

"Sunny, are, are you alright?"

She panted and shook. "That felt—it hurt for a second but now it feels good."

"Okay. I'm taking your temperature, Sunny. You're hot, do you have a fever?"

"I don't think so, put the thermometer in deeper."

He pushed deeper and her filly parts made his ding-a-ling all wet and hot it and felt really good and he liked playing doctor.

Something made him pull back out. He didn't know why, since being in felt so good, but Hitch couldn't stop himself. But wowie, that felt great! Her filly parts were still all wet and warm and squeezed on his ding-a-ling and it felt super duper good as he pulled back. He looked down again and saw that there was only the one tiny drop of blood on his ding-a-ling from her.

"Hey, don't pull out!" Sunny said. "You have to finish taking my temperature."

Hitch pushed back in and they both yelled "WOW!"

"That-that felt amazing," Sunny said.

"Yeah."

Hitch pulled out again.

Hitch pushed back in again and they both shouted "Wow!"

"Should I just keep doing that? That feels neat," Hitch said.

Sunny nodded, biting a lip.

Hitch started pumping his ding-a-ling in and out of Sunny's filly parts. She got him wetter and wetter and warmer and warmer and his ding-a-ling kept getting stiffer and stiffer and his peanuts tingled and pulled up against his underside.

Sunny started gasping her her filly part got tighter and wetter around him and then she screamed "TWIIIILIGHT SPARKLE!" and suddenly Hitch's entire underside was soaking wet.

He pumped harder and faster and his peanuts felt really weird and then his vision went dark and something really weird happened.

"Whoa!" Hitch said.

"What?" Sunny gasped. "Why'd you stop?"

"I think-I think-I think I might have peed inside you."

"Oh gross!" She shimmied forward, out from under him, and he dropped back to all fours. Sunny flopped onto her back and bent into a half-circle to look at her own filly parts. Hitch stared at them, too. The drop of blood was still there, along with a small dribble of something white.

Sunny touched it. "It's sticky?"

"It's not pee," Hitch said. "That's weird."

"Yeah," Sunny said. "Wanna go play Guardians of Harmony again? I want to be Twilight this time."

"Yeah."

xXx

Argyle opened the door and trudged into the house. Something smelled funny, but he assumed it was some aftereffect of the medicines the doctor had given him. He heard the two foals giggling upstairs and went to check on them.

Hitch and Sunny played with the six figurines Argyle had carved for her. He smiled, glad to see Hitch accepted her games of unity among the three kinds of ponies, even if Sprout wouldn't.

"Daddy!"

"Mr. Argyle!"

"Hey, daddy, we have a question for you."

"Oh?" Argyle said, pushing his glasses up his nose.

"Is it possible for a colt to pee sticky white stuff inside a filly while playing doctor? The strangest thing happened."

Argyle closed his eyes and counted to ten. Then he counted to one hundred. Then he went to a locked cabinet and pulled out a box of condoms and gave them to Hitch. "You'll want these," Argyle said, and went to his library to translate some more ancient texts. He couldn't deal with this today. He just couldn't. Not after what the doctor told him.

Sunny and Hitch looked at the ten-pack of condoms and then looked at each other.

"What?" they both said.

Hitch opened one of the wrappers. "Balloons?"

"Balloons," Sunny said.

xXx

Sprout almost made it into the school before the ice-water filled condom burst against the top of his head.

He looked up at Sunny and Hitch on the balcony. "You two! I'll tell my mom!"

Hitch and Sunny looked at each other and chanted, in harmony, "Up high, down low, hitch it to a post! Flip it sunny-side up and on a piece of toast!"

Then they hugged and dissolved into giggles.
