"Well," Runt said. "A deal is a deal. You can have it back now."
I was only barely paying attention. I was still sucking on my own cock, enjoying the feeling of both giving and receiving a blowjob. Suddenly, though, it started shrinking in my mouth. I moaned a little and kept sucking, trying to get the last bits of come in my mouth before my dick disappeared completely.
"Mmm, you're pretty good for an amateur!" Runt said. He was rubbing the back of my head approvingly.
My reasonable endowment had shrunken down to about an inch and a half at this point. With one last suck, I leaned back from Runt's crotch. His other dick looked larger than before. Quite a bit larger, actually.
"Why was I so enthusiastic about that?" I asked, slightly coming back to myself. I can't believe I sucked him off! And I definitely had enjoyed it, though it was slowly becoming harder to imagine liking the feeling of a dick in my mouth.
"I have an effect on people." Runt smirked and looked pointedly at my dick.
Oh, right. I have my dick back. How did I forget about that part of the deal? I sucked him off, and now I have my... manhood...
"What the fuck?!" I yelled angrily at Runt. My dick was about 3 inches long, and hard as steel from being in proximity to him. My balls were back too, but they, oddly enough, seemed larger than they were originally. I could sense their heft. My package felt off-center, like weight was in the wrong place.
"Oh, I thought I'd keep a little bit. You know, a memento." Runt was grinning devilishly.
"Come on, dude, I blew you for my cock back. Can't I get the rest of it, too?"
"I don't hear any complaints about your balls!"
"Trade ya?" I didn't mind the larger set, but I'd trade down in ball size to get my dick to its former glory.
Runt laughed. "It's never so simple. Don't you know that by now?"
"I'll... suck you off again?" It didn't sound quite as appealing as it probably felt five minutes ago, but I figured that would come back to me.
"You're getting warmer..."
"I'll... fuck you?" I didn't really want to think about his ass. But it was definitely pert. Nice and firm and probably as tight as a virgin and actually, even with a smaller dick it would probably feel amazing and it's not like he would care, right? And holy shit what if it grew while it was IN h--
"You're almost there!" Runt was smirking confidently. He swished his hips the slightest bit so that his recently-improved pendulous dick gave a hefty swing.
Fuck. "Um." How bad did I want my dick back? I looked down at the tiny thing. Having less than half of my natural size for the rest of my life?
"I could, of course, find someone else more willing..."
"No!" The thought of Runt giving someone else my dick length was all the motivation I needed. "Please... I'll do it."
"Do what?" The impish grin was back.
