In the moments of my decision, I was clear-minded. Runt wasn't manipulating my mind. I even started to feel a little odd about being fucked like this.
But when assessing my true desire, I knew I couldn't say no. The feeling of being with Runt was indescribable, and I couldn't wait to experience more. I knew my desires might change along with my body, but I couldn't deny the thrill of the unknown. The opportunity was too great, and I would live the rest of my life wondering 'what if..?'.
"Runt," I began huskily. I cleared my throat. "Runt, I can't walk away from you now. I feel weird saying this with a foot of your cock lodged in my ass, but this has been the best time of my life and I've only lived it a few short hours. I have to have more of this, and more of you."
Runt grinned, but there was earnest happiness instead of mockery in his face. He looked back down to our bodies, seeing the paused scene before him. "Whaddya say we... finish this?" He winked, back to his cheeky and horny self.
Desire washed over me as clarity, ironically, lifted like a fog and I delved back into my impassioned haze. I rocked back and forth on his dick, reminding myself of the feeling of it deep within me.
Runt rolled us over, holding me by the waist yet again, and laid me on my back. He took my hands from my chest and tiny prick and moved them to my legs. I held myself wide open for Runt and he grinned, backing up and then fucking into me. He began smooth and slow and built up to pulling in and out swiftly, moving back and then slamming me forward onto the bed. With his free hands he reached for my chest and massaged my newly sensitive nips. As he squeezed them between his fingers I moaned as if I were getting my dick sucked. Despite it being ignored, it was rock solid is ever, still on the edge of this orgasm to end all orgasms.
Runt leaned forward onto me, whispering to my ear again. "Ready?" was his one-word question, bearing the weight of our conversation. "Fuck yes" I whispered back, thick with need.
He pulled back entirely, nearly coming completely out of my ass. Even from my perspective I could tell that rather than a foot, his cock must have stretched to at least 14 or 15 inches, while maintaining the same wildly thick girth. He gave me a toothy smile with pupils blown wide, and slammed deep into my ass as we both hit our peak.
"Coming" doesn't begin to describe the ecstasy.
Simultaneously I experienced a million sensations. I felt Runt's cock slide into my ass, widening as it went deeper than it even had before. I felt my ass-lube leaking out of my wrecked hole. I felt my legs lower and wrap tightly around Runt. I felt a shock of euphoria as he hit my prostate, as though it were more sensitive than throughout the rest of the fuck-session. I felt Runt's engorged balls slap into me. I felt my own pent-up balls tighten in anticipation. I felt my hands drift to his ass and grab. I felt Runt's talented fingers leave my teased-erect nipples and slide behind my back and lift me into him. I felt him lean forward and, surprise of surprises, catch my mouth in a passionate kiss. I felt Runt unload into me, deep and powerful, jets slamming into me like nothing I could compare to. I felt my own dick, though small and left untouched for some time, shaking in pleasure as I came harder than I had ever been able to imagine. I felt the come shoot from my swollen balls down the short distance and out, splattering onto Runt's abs again and again.
And then, I felt the change. Runt's dick continued shooting, but I could feel it shrink as it did. Half an inch at a time, all while we continued to make out, each shot reduced his mighty size. At the very same rate, my dick was engorging and plumping up, still managing to shoot from my over-producing sack. The shifting continued as Runt deepened our kiss, and I felt my own dick reach its old size in no time, and then surge again, taking up more space between us as Runt laid fully on me.
My cock swelled with a few more smaller spurts, pushing into its own mess on Runt's abdomen. His own dick was still dwindling down, receding from within me as if he were pulling out tortuously slowly.
Finally the exchange slowed to a stop, and Runt slowed his tongue-fucking of my mouth until we finally pulled apart. He separated from me, where I saw an absurd amount of my come on his stomach. As I dropped my hands and he pulled his now-average dick out of my hole, I looked down at my own. Still semi-erect, it had to be about 9 inches in length, and girthier than I remember. I grabbed it just to feel the heft, and hissed at the overstimulation.
"I approve," I said to Runt.
He landed back on the bed next to me, a mischievous glint in his eye. "So now that that's done, I think I have an idea of what to do next."
