Rainbow Dash let her body bounce back and forth as Pinkie and Applejack thrust at her from both directions. Applejack moved slower. Not slow, but her humping was more deliberate, as if she was savoring every inch of Rainbow Dash's ass. But Pinkie... in true Pinkie Pie fashion she was simply pounding as fast and hard as possible. The thrusts blurred together, until Rainbow Dash could barely even tell them apart.

Pinkie giggled as she fucked. It was so much fun having a dick. It was like having a giant clit that you could could fuck someone with. Best of all, it left her hands free. At first she simply used them to grope at Applejack, which was pretty great. AJ had some pretty great tits, after all. Of course, that got Pinkie thinking about how her own tits compared, which immediately led to her groping herself and realizing that it felt really really good. But if rubbing her own boobs felt good, rubbing her other parts must feel even better. Currently, one hand fumbled with her nutsack, and the other pinched her nipple. Her other nipple was in her mouth; she felt almost embarrassed that she had never realized that she could suck her own boobs. The only thing that could make it better was if she could get chocolate milk out of it. That was what boobs were for, after all. Aside from being totally sexy, their main purpose was to make milk. It couldn't be that tough for Twilight to add some chocolate to it.

It flipped a switch in Pinkie's mind. Between the chocolate milk boobs and the pudding penis, she could turn herself into a walking dessert bar. Maybe Twilight could come up with a spell that would let her poop chocolate frosting or something. Her pee could be... lemonade? That wasn't very desserty. It had to be a liquid though; pissing anything more solid would kind of hurt. Lemon Jello! Of course! Sure, she'd have to remember to piss in a bowl and leave it in the fridge for a bit, but that was hardly a problem. It was the perfect plan! She'd never run out of sweets ever again. Maybe she could even get Twilight to make her boobs different flavors. Left boob could be chocolate milk, and the right once could be like... she didn't even know. Maybe root beer or something. Or cider! Duh! It was like the most obvious thing ever. Although now that she thought about it, peeing cider would be even more convenient. The stuff went right through her anyway; she'd just have to drink one and she'd be able to endlessly recycle the same cider! It was BRILLIANT!

Pinkie's brain was shuffling through the ideas so quickly that her instinct took over the fucking. As more and more ideas popped into her brain, she thrust faster and faster. She was merely subconsciously aware that an orgasm was creeping closer and closer to completion.

Or maybe I could make each ball make a different kind of pudding! One could be chocolate and one could be tapioca! But then would I be able to choose which one I wanted? Chocolate and tapioca don't mix! But wait, where would the ice cream come out of, then? If I could cum ice cream it would be awesome. Maybe mint chocolate chip. No, nothing with chunks; that would be painful. Vanilla? Too boring. Chocolate? Nah I'm already crapping chocolate frosting. Mint maybe? No! I know! It should totally be--

She came.

"CHOCOLATE CARAMEL SWIRL!" She arched her back and shoved her dick as far into Rainbow Dash as it would go. She could feel her dick pumping cum into Rainbow's pussy. Pinkie squeezed with muscles she didn't even know she had, eeking the last few drops of semen out of herself. She thrust a few more times, slowly, with a loud squish as the cum oozed out of Rainbow Dash and dripped down the shaft of Pinkie's cock. "Aaaahh..." She sighed blissfully an let herself fall backwards onto the bed.

Her dick made a wet pop as it slid out of Rainbow Dash and slapped against her belly as she landed on her blanket. It twitched, and a few final drops of cum spilled out. Pinkie scooped it onto her finger and popped it into her mouth. "Eh, a bit too salty." She looked up at Applejack, who was still grinding furiously against Rainbow's back. "What's taking you so long, AJ?"

"Shut up! You were already halfway there when I jumped in! I'm gettin' as much outta this as I can!" She wrapped one arm around Rainbow Dash's chest, squeezing her nipples. With her other hand she edged closer to Rainbow's crotch. She tugged a bit at the tiny patch of hair above her pussy. Rainbow squeaked. "Yeah, you like that, don't ya? Pity you didn't have a bit more endurance. It woulda been nice to come at the same time."

"No-not fair!" Rainbow gasped. "I was getting f-fucked by both of you!"

"So you wanna take me one-on-one sometime? Maybe we could get you a dick of your own and then we'll really see who's who!" Applejack's hand slipped lower. Her fingertips sank into Rainbow Dash's slit. She slid under the delicate folds of skin and reached the clit. It felt like a soft little bean, pulsing with every heartbeat. "Hang on tight," Applejack said. "Things are about to get fun!" She squeezed. Rainbow Dash's knees buckled. She tumbled forward, only just barely catching herself. She landed on her hands and knees on the bed, straddling Pinkie, who was lying back and watching the spectacle. Applejack fell with her, somehow managing to keep her dick inside Rainbow's ass.

"What you, thought you were gonna get away?" Applejack grinned. "I ain't quite done yet!" She grabbed Rainbow Dash's waist and began to thrust as hard as she could, her eyes surveying RD's well-tanned back.

"AJ... I- I..."

"If you're gonna cum, cum! I'm just about there! Why don't you give her a hand, Pinkie?"

Pinkie nodded, and shoved her fingers into Rainbow's vagina, waggling them as hard and fast as she could.

Rainbow Dash's body gave out completely as she came a second time, her secretions pouring over Pinkie's hands. She collapsed on top of her, her face landing smack-dab in the middle of Pinkie's ample chest. Applejack gasped as Rainbow Dash's anus contracted, squeezing tight as she orgasmed. Applejack took a deep breath, thrust one last time, and whipped her hat off.

"YEE HAW!"

Her toes curled as her cock pumped cum into Rainbow Dash's ass. She shuttered with each shot, her entire body tightened with pleasure. As she finished, she patted Rainbow Dash on the back. "That felt great! You got one hell of an asshole, Dash."

"Y-yeah..." Dash mumbled from between Pinkie's breasts. "Right now it feels like you got your entire arm shoved up in there."

Applejack slowly slid her dick out. Even though she had come, Rainbow Dash's butthole still had a pretty tight grip. "There we go!" Applejack's half-erect dick came out with pop. "Whew! That was quite something." She looked down at it, and caught of whiff of the combo of cum, lube, sweat and butt-smell that lingered on it. What was left of her boner rapidly disappeared. "I guess the aftermath ain't that great. She sat on the bed next to Rainbow Dash, took a tissue and began wiping her dick clean.

"Ugh, I'm not gonna be able to walk straight for a week," Dash groaned as she rolled off of Pinkie and onto her back. "My ass feels like I sat on a road cone."

"Oh, please, you were totally into it!" Applejack chuckled as she laid back on the best next to Rainbow Dash and Pinkie.

"Well, yeah," Dash answered.

"So can we cuddle now?"

"Huh?" Both Applejack and Rainbow Dash looked at Pinkie.

"What? That's what you do after you fuck, isn't it?"

"Sure, why the hell not?"

"Great!" Pinkie rolled onto her side, sliding one arm and one leg under Rainbow's body and snuggled up against her. Applejack did the same, her now-flaccid wang flopping onto Dash's leg. She pressed herself against Dash, and began to nibble at her ear.

"Don't think I forgot, Applejack," Dash said.

"Forgot what?"

Rainbow grinned. "You said that I oughta get a dick of my own so that we could really compare. You know I never back down from a challenge."

Applejack rolled her eyes? "Fine, sometime I guess we'll have to get you a dick. Not now, though."

"Why not?"

"Because we don't want to wake Pinkie."

They looked at her. She was already starting to snore.

"Fine," Rainbow Dash said. "Maybe tomorrow."

Author's Note

sorry this took so long

real life things. So yeah this is pretty much done; maybe it'll have an epilogue like the other story and then we'll have a followup. No way I'd pass up on AJ and RD having a dick contest

also, if you're wondering what pinkie's dick looks like (both links NSFW obviously. and if you prefer to keep your own metal images, just don't click it):

Non-boner

boner

except with slightly larger balls
