Applejack didn't knock. There was no time for knocking when her friends might very well be hurt. She threw the door open. As it happened, the crash had been the sound of the furious humping causing the legs of Pinkie Pie's bed to give way, sending the entire thing to the floor. That, of course, was not the first thing that Applejack took note of. The first thing she noticed was that Pinkie and Rainbow Dash were both naked. The second was that they were in such close proximity to each other that either they were in danger of freezing to death and were trying to share body heat, or something kinky was in the works. Given that it was a balmy eighty degrees out, Applejack assumed the latter. The third thing she noticed was that the particular position they wasn't exactly the most efficient one for two girls to do sexy things in. Now, if Pinkie were a guy, it would make perfect sense, but...

The realization hit Applejack like a ton of bricks.

"What the hell are you two doin'?"

"Isn't it obvious?" Pinkie asked. "We're fucking!"

"But how could you possibly be--" Then she saw it. "Pinkie, did you just suddenly grow a dick, or are my eyes just playin' tricks on me?"

"Nope! Now I totally have a penis too! It's pretty awesome. I'd show it to you, but it's kinda busy at the moment."

"Yeah, somehow she managed to get a- wait." Rainbow Dash processed Pinkie's words. "What do you mean you have a penis too. It's not like Applejack has a dick."

Pinkie shrugged. "Well, maybe not now..."

"Wait, you had a dick?" Rainbow Dash stared at Applejack. The latter's blush told the former all she needed to know. "You did, didn't you?"

"M-maybe...." Applejack's pupils bounced around like pinballs.

Rainbow Dash's eyes were drawn to Applejack's crotch. "Applejack, you don't still have one, do you?"

"N-no."

Rainbow Dash snickered. "You are a terrible liar. I can see the bulge in your pants."

"What bulge?"

"That one!" Rainbow Dash pointed. "It's kinda- Pinkie what are you doing?"

Pinkie was still lying back on the bed, bouncing her hips. "What? I gotta keep it up. Can't just let it sit there! It's not like I'm gonna cum without you or anything. Just let me know when you're really ready to get back to business!"

"Yeah, okay." Rainbow Dash turned back to Applejack. "I'm talking about that!" She pointed again at Applejack's crotch. "You're pretty obviously starting to pop a boner there!"

"I am not!" Applejack's face flushed.

"Come on, AJ, I can see it moving!"

Applejack looked down. Rainbow Dash was right.

"You're getting a hardon from watching me and Rainbow Dash?" Pinkie giggled. "You wanna get in on the action?"

"No!"

"Why don't you at least take it out?" Rainbow Dash said. "Looks like your pants are gettin' a bit tight there."

"Why are you so curious about my not-boner?" Applejack snorted.

"Oh come on, if I suddenly sprouted a cock, you'd probably want to see it! Can you honestly tell me you wouldn't be a bit interested?"

"No! Well, maybe a bit..."

"Well, out with it, then!"

"Damn it, I can't believe I'm doin' this..." Applejack kicked the door closed and unzipped her pants. "Here we go." Her semi-erect dick flopped out like a big, squishy sausage. She waggled back and forth and bounced it a few times. "You happy now?"

"Not bad. Looks a bit thicker than Pinkie's. Not quite as long, though."

"What you wanna just pull her dick out and have a measurin' contest?"

"Nope, can't do that!" Pinkie said. "My dick is busy, thank you very much."

"Here, come closer!" Rainbow Dash caught the tip of Applejack's foreskin between her fingers and tugged.

"Ow!" Applejack took a step forward. "Don't do that! It hurts!"

"I dunno." Rainbow Dash grinned gave AJ's penis a squeeze. "I think you actually kinda liked it. You're getting harder." She began to stroke it. Now it had definitely crossed the line from semi-erect to full-on boner, and due to the fact that the bed had collapsed, it was right at blowjob level. "Yeah, you're totally into it. Oh well, no point in letting a good boner go to waste." Rainbow Dash pulled back the foreskin, admired the head for a moment, and popped it into her mouth, and began to lick.

"Okay, that feels pretty good, but if you're gonna blow me, you gotta do it right!" She put both hands on Rainbow Dash's head and shoved her hips forward. Her entire penis disappeared into Rainbow Dash's mouth. "Now that's more like it!"

"Applejack, you're messing up my fucking!" Pinkie glared at her. "It's totally throwing off the timing of my thrusts!"

"Well, what else am I supposed to do? You guys are the ones who dragged me into this!"

"Why don't you fuck Rainbow Dash too? She's got another hole down there, after all."

"I dunno..." Applejack looked remarkably pensive for someone on the receiving end of a blowjob. "I'm not sure I want to put my dick up her butt."

"Have you ever tried anal before?" Pinkie asked. "Maybe you'd like it!"

"Well, kinda... not on purpose."

"How do you do that by accident?"

"The two holes are close together, okay? I was in a rush to start the bangin' and I stuck my cock in the wrong one."

Pinkie snorted. "The wrong hole! That's a classic! Good thing you didn't do that to Rainbow Dash now! It would be much fun to have a dick up your nose."

"I don't think it would fit, anyway," Applejack said. "I mean, it's not like my cock is enormous or anythin', but I don't think it'd go up her nose."

"Well, when you stuck up the ass did you like it?"

"I'm not sure; it wasn't up there for more than a few seconds. It didn't feel too bad, I guess."

"Well, why don't you give it a try, then?"

"I guess I could..." Applejack took a step back and popped her dick out of Rainbow Dash's mouth. "How 'bout it, RD? You up for takin' it up the behind?"

"I guess I might as well." Rainbow Dash wiped her mouth. "At least that way I can talk, too. Seriously, I never knew that you could talk that much while you have sex."

"Just a sec, let's get into a better position!" Pinkie said. "Help me up!" Applejack grabbed Pinkie's arms and pulled her upright. "Okay, now stuck your dick up her ass and let's get going!"

"Okay, here it comes!" Applejack stepped forward.

"Wait just a sec!" Rainbow Dash barked. "Put some lube or something on that thing before sticking it anywhere. Pinkie's gotta have some around here someplace!"

"It's in my drawer!" Pinkie nodded at it.

Applejack slid the drawer open. "Holy moly, that's a lot of dildos! What the hell do you do with all these things, Pinkie?"

"I like to have some variety! You're free to borrow some of them if you want!"

"Nah, I think I'll be okay." Applejack pulled a bottle of lube out and squirted some onto her dick. She raised an eyebrow at Rainbow Dash. "What do you say we get down to business?"

Of course we all know that Fluttershy's dildo collection puts Pinkie's to shame.
