"I'll let you... fuck me," I said uncertainly. The thought didn't sound particularly appealing; I'd never even tried sneaking a dildo from any of my old girlfriends. But as soon as I said it, I could see myself possibly enjoying it.
Runt smiled at me. He knew exactly what I was thinking, and he saw that my tiny dick was still rock hard. "Quite the romantic, but I'll need a little more encouragement than that."
"Oh come on, dude. Please? Please fuck me and grow my dick back?" Once I started begging, I couldn't stop. It felt... right. "Please put your huge cock in my ass!" It would feel awesome. That's right where his huge cock needed to be.
If I were in my right mind, I would have been worried. Not about the gay thing, but about the sheer size. He looked to be about 8 or 9 inches soft, and he was rapidly chubbing up to something near 11 inches hard. The idea of two fingers in my ass to my sober mind would be daunting, but in this moment I knew his dick would fit in my ass perfectly.
We were still just standing in my living room. Runt came over to me, his swagger making his dick thwap against his thighs from side to side. The visual was purely intoxicating. By reflex I immediately knelt down to give it a lick.
Runt snorted a bit and pulled me back up. "You're just a little horny slut now, aren't you?" I didn't feel an ounce of shame at his words, but instead I leaned into his neck, deeply inhaled his musk, and began tasting his skin. The smell was one of the most erotic things I'd experienced through my nose.
I felt myself being lifted by the underside of my ass, each of my legs straddling Runt's waist. I continued sucking on his skin and licking his neck while he carried me to my own bedroom. I was helpless to resist him.
"Let's get a little more comfortable, eh?" Runt said, tossing me back onto the bed. Spread-eagle on my bed, I felt hornier than I had ever been in my life. I moaned when he stepped away.
"Come back! Look, my ass is so ready for your juicy cock." I flipped over and started wagging my ass at him as if I had a tail. Ooh, now there's a thought. Wait. Wasn't I trying to un-transform? I don't want to go any further, right? While my thoughts went down a detour, my fingers inserted themselves in my mouth, slobbered them up, and two went straight to my ass. It was impossibly tight, and not exactly pleasurable. I grunted in frustration. "Ruuuunt!"
"Wow, you're more receptive than I expected." Runt had just walked across the room to open a window. I imagined I might get a little hot being fucked by an imp. I felt the bed dip when he climbed on behind me. He pulled my fingers from my asshole but I didn't have an instant to complain before he shoved his face between my cheeks.
"Ohhhh, yeah, eat my fucking ass!" I had no clue where my words were coming from, but they felt nice to get out, like not saying them would be holding back on some of the sexual pleasure. I felt the stubble on his manly face (was it there when he came in?) scratching pleasantly against my ass as his tongue darted in and out to lick my hole. Whereas my fingers couldn't seem to get the job done, every swipe of his tongue was ecstasy.
"YES!" I screamed when his tongue pushed through my tight hole and started massaging the inside of my ass. I could feel Runt exhale like I'd told a joke with the breath coming out of his nose. I wiggled my butt, trying to grind against his face and get more of the fascinating friction of his scruff and more of his tongue in my ass.
He seemed to know what I wanted, because I suddenly felt his tongue getting longer in my ass. It was indescribable. He licked the tight ring at the entrance, then pushed deeper and deeper into my ass, licking the insides the whole way. "FUCK!" I yelled again when he hit what must be my prostate. With his tongue! He continued licking all around the area.
Somehow, I wasn't coming. It felt like I was continually on the verge of orgasm, again and again reaching an edge that I just couldn't fall over. I figured Runt wasn't going to let me come so I stopped trying to hold back at all. My hands, which had previously been tightly clenching the bedsheets and pillows, moved down, one on my tiny prick and another on a nipple. I'd never particularly considered nipple play to be something I reacted to, but this time it was like fire shooting from my chest to my dick while I pinched and twisted. And at three inches, my dick needed little more than an index finger and thumb to stroke. Pre had been leaking from it like a faucet, probably thanks to my engorged balls producing way more than I needed. Almost like stroking a short pencil, my fingers ran up and down my dick like lightning.
While I played with myself, Runt finished up licking out my ass. He pulled his face back rather than shorten his tongue, and I felt the weird sensation of it sliding backwards out of my ass. I looked back over my shoulder to see his tongue hanging out of his mouth. He grinned and slurped it back in to a more normal length. I glanced down to his cock and saw a solid foot of dick, gleaming with pre-come, and he looked ready to pounce.
"Fuck," I gasped. Feeling the edge of about ten orgasms was exhausting me already. "Shit, don't you need to get some lube first? Pre won't be enough."
"Do you think I was licking you out only for fun? Feel your ass." Runt seemed proud, like he'd solved some problem creatively.
I tentatively removed my hands from my dick and nips and reached back to my ass. The first thing I noticed when I felt my cheeks was that they were definitely fuller. Like, ridiculously... bubbly. "You gave me a bigger ass?"
"Keep going..."
As I felt my improved bubble butt, I reached down the now deep crack and started feeling dampness. I thought it was just some saliva at first, but it was ridiculously slick. When I pressed at my hole with two fingers, they slipped in like nothing, even though my ass felt tight. It was lube! "What the hell..." I mumbled. I felt about a finger-length into my ass and the sides all felt extremely slick.
"When you're horny, now your ass lubes itself!"
"What the fuck?" The surprise, and weirdness, of the situation brought me slightly out of my horny fog. I jumped out of bed and went to the mirror. Standing and looking at my profile I noticed how very prominent my butt was, followed by how its large size made my small dick look even tinier. If I could fuck myself, I'm not even sure my dick would make it all the way to my hole!
I pulled my cheeks apart after removing my probing fingers and looked back at the mirror again. My fingers were soaked in some sort of lubricant and my ass was fucking drooling!
"What the shit, Runt? It's like I'm wet like a bitch in heat!"
"That's where I got the idea! Good catch."
"Can you make it stop?" I asked.
"Of course. But do you really want me to?" Runt considered me with a strong look.
I thought about it. Honestly, it's not really a negative thing compared to completely losing my package or having it replaced with this tiny prick. If anything it'd be useful, and maybe a slight inconvenience to my underwear.
"... No, not really," I answered.
"That's what I thought. Now come back to bed." His eyebrows said all I needed to know, and in an instant my extreme need for sex was right back where it had been. I jumped back in the bed, face down. My ass felt empty, like now instead of insertion being an intrusion it would be the norm.
"Fuck yeah. Fill my ass good!"
