A Brief Window of Opportunity

I look down between my legs. Some time between ejaculating confetti and now, I had grown a second penis. A little worried, I check Twilight out really quick. She's still female. And I can't quite tell from here, but I don't think she has two vaginas, so it wasn't the mints. Maybe I'm just tripping. I reach down and fondle the penis that was sprouting out a little higher-up on my body; it was thicker, longer, and more horse-like than my own, but it was definitely attached to me.

Just to make sure, I reach my other hand a little further and grab onto the other one, penis classic. As far as I can tell, they're both real and both mine. Assuming that it's not just the drugs messing with my head, this is gonna be kinky. Twilight giggled and snorted at the sight of my grasping my dicks, smiling stupidly. She seemed to be pretty damn high, even though I still didn't feel anything.

Her reading quickly glasses found themselves on the side of the tub, and with a deep breath, she plunged her head under the water, and I felt her mouth wrap around the newer, larger penis, as she performed a simple blowjob. After about thirty seconds of that, she pulled back, her nostrils moved just above the surface of the water, and she inhaled again. Then she shifted her whole body, hanging her hindquarters up and out of the water, and hooked a back leg over the edge of the tub for leverage.

She took another deep breath and dunked her head in once again, wrapping her mouth around my penis. This one was longer than my own, so she was able to push forward and get it quite deep into her throat. However, she wasn't handling it quite as well as Pinkie seemed to be able to. I could definitely feel her gag-reflex nearly being set off every time she took me all the way in.

Another thirty seconds and she had to come up for air, but it wasn't long before I was deep inside of her again, feeling the delightful warmth and tightness of her throat around my member. I wanted to reach out and touch her plot, but I knew she was in a vulnerable and unstable position— if she startled and slipped with my penis that far down her throat, especially while she was also underwater, she could really hurt herself. I suddenly wondered why she didn't tie me up... I guess she must have assumed that I'd never try to run away wet, naked, and — I guess — stoned, with an extra penis.

Her head breached the surface of the water once again, and she looked into my eyes as she shifted towards me. She gently dropped herself down onto me, taking the smaller dick into herself. The spacing was such that the lower side of the horsecock I had spontaneously grown was able to rub against her clit, doubling the stimulation she received. She moved herself up and down very, very slowly, savoring every moment. Either the mint or whatever was in the bath water was really helping me last longer, too— I was feeling a sustained pleasure quite unlike anything I'd ever felt before.

So that was why Twilight wanted to go last. Who could ever hope to follow this act? As she carefully moved up and down, she swung her head around, loose and free, her wet mane hanging around her head. Her hooves grabbed onto my hands, which were clenched around the walls of the tub, and dragged them down into the water, bringing them to her supple purple rump. I squeezed her flank and rubbed her plot gently as she continued casually riding me. I kept massaging her flank, slowly growing more and more adventurous. One lone finger wandered close to her asshole.

"OoOohh," she moaned, slowly nodding her head back and forth. Did she want it? I think she wanted it. As my finger just penetrated her anus, she threw her front hooves over my shoulders, bringing herself closer to me. With a pant, she whispered, "Yes... Yes... Just like that..."

I pressed in a little deeper. She was already lubricated, so it was quite easy playing around with her asshole. I moved my finger in and out in time with her own motions.

"Mmhhh... Another..." She muttered, continuing to ride me. I carefully inserted another finger, stretching her out a little more, and used both of them to screw her. I finally came, simultaneously shooting off a load inside of her and all over her fuzzy chest. She reached down and pulled my hands away from her flank, stood up to get a little closer, and put her lips to my ear, sensually whispering, "Again?"

I nodded, mouth hanging open, drool dripping down out of it. She cast her resetting spell on me for the sixth time that day, and then dropped down, taking the larger horsecock into herself.

"Unhhh..." There was just something about the sounds she was making that was undeniably comforting and sexy. She was only taking in the head, but she lowered herself down a little further with each slow, passionate stroke, until finally my lower, smaller penis touched against her anus. She stopped moving up and down and just slowly, slowly, unbearably slowly pressed downward, leaving me overcome with the sensation of double-penetrating someone all on my own. It wasn't just a matter of doubled feeling, it was a combination that defied understanding— both distinct feelings being overlaid on top of each other, driving me wild with mutually-exclusive — but nevertheless mind-blowing — sensations.

She shuddered as she continued to lower herself, rocking back and fourth and gradually taking both of my penises completely into her body. When her flank finally touched against my thighs, she stopped moving, and grabbed at the hand that hadn't been playing with her ass, bringing it near her clitoris. I rubbed away at it, which prompted the unicorn to make more soft, lovely, moaning sounds. Little sparks of magic started flying off the tip of her horn. I thought about maybe trying to massage it, but it looked a bit too sharp for comfort, and I wasn't sure if that was even an erogenous zone.

She leaned far backwards, taking my natural penis deep into her ass while pulling the horsecock almost all the way out of herself, and then made the opposite motion, leaning all the way forward, the horsecock pressing against her cervix and my original dick just barely staying inside of her. She continued rocking back and forth, alternately moving both dicks in and out of herself. It was too much for me to handle. I couldn't— I just— I came again, filling her up with my hot seed.

Twilight didn't stop. She kept on going. "Again," she whispered, casting the spell on me once more. Fifteen seconds of her riding me later and her wish was granted, yet more of my ejaculate filling up her tight, warm, orifices.

"Unhhh... Unf..." She moaned, "Again... Again..."

She refilled me once more and kept on riding me. She was definitely doing something to increase my stamina, there's no doubt about that. I orgasmed for a third time just twenty seconds later. I was starting to feel pressure build up inside her and my semen was starting to squirt out of her with each downward thrust of her body.

"Just... a little... more... Unnnnhhh" She added, panting. The spell was cast again.

A few seconds later I started coming, and at that moment, Twilight's horn began spouting a persistent magical glow. I didn't stop. It just kept pouring out of me, and then back out of her, like a faucet. I had literally never, ever, ever felt anything so incredible in my life.

"AHH-huh-huuuuuhh" She gasped, little spurts of magic flying from her horn as the spell she was casting died down. Without bothering to take me out of herself, she leaned forward against my chest and nuzzled my cheek. I wrapped my arms around her and rested my head against hers. Oh, why can't I take you home with me?

"Yes, again." I said, stroking her gently.

"Huh?" She asked.

"I would definitely like to come back."

"Oh... Yeah..."

She seemed kind of out of it. Suddenly, I remembered something important. I needed to go home soon. She was my ride home, and... she was intoxicated.

"Is... Is she gonna be okay?"

"Oh, yes, of course," Rarity replied, "she always gets like this after a good lay. Give her about two minutes."

Hmm, okay, a couple minutes. Should be fine. I continued stroking her... Withers? I think that's the right term for the upper part of a horse's back. As great as the sex had been, this was somehow even better. Just laying there, in the tub, gently touching her body, feeling her heart beating close to my own. I'm not sure I'd ever been quite so happy.

She took a deep breath and nuzzled me a bit. I felt like my heart might have nearly exploded right then and there. My fingers were starting to prune, for having been in the tub too long, but I didn't care. I was enjoying myself too much to get out. Even just feeling her breathing up against me was inexplicably satisfying.

"Yes, yes... I'm definitely going to want to see you again..." she remarked, seeming to have partially regained her composure.

"But when?"

"It's impossible to know... We can't predict where the portals will be more than a month in advance... And they're so rare."

"So I may not get to see you again?"

"Sadly, no. But you got to see me once. That's more than most can say."

"Mmhmm..." I mumbled, squeezing her a little tighter.

"Fluttershy..." Twilight yawned. "How's the time doing?"

Fluttershy looked over the clock apparatus. Now that I could see the face, it appeared to be fantastically complicated.

"Oh... Um... I think... I think there are forty-five minutes left. No, wait, forty-three. Um... Forty minutes."

Twilight instantly sobered up as her eyes shot open and she leapt out of the tub, spraying water all over the room. "No, no, no! Those aren't minutes, they're seconds!"

I was magic-lifted out of the bathwater, left dangling kind of awkwardly, dripping on the floor, and abruptly set down. Twilight scratched her quill at parchment like mad, doing some kind of crazy math problem. She grunted in frustration, crumpled up the sheet, and started over.

"Fifteen seconds!" Rainbow Dash shouted.

"Aha!" Twilight had gotten it. She concentrated, built up a strong charge of magic on her horn, and unleashed it upon me.

The others waved goodbye as I felt myself fade out of existence.

Author's note;

Well. My first clop-fic. I never thought I'd write anything like this, but... It's been fun, guys. Thanks for reading, and for whoever has stuck with me since the end of chapter 2, thanks for staying through the scare that was Rarity, and the anxious pause in the story to find out what exactly Fluttershy was planning.

There are a few different endings coming up after the break. I couldn't decide. The first one is the one I consider 'canon,' but you can believe whichever one you like best.
