...started laughing. "You know what, let's keep going!" Before I could say anything, Runt dove back onto my dick and I started expanding more!! I moaned as all my clothes snapped off once again and I felt my muscles ballooning out in all directions.
When I finally stopped, I could only stare at myself in the mirror. My legs were tree trunks, and I had to adopt an incredibly wide stance because they pushed against each other so much. My massive shoulders and neck made my head look puny in comparison to my body, and my tight waist and abs only accentuated how cartoonishly huge my pecs and ass were. Runt grinned: "I always liked a little t&a." He chuckled as he grabbed and bounced one of my huge pecs, which indeed felt like more of a big muscle tit now.
Runt continued: "Well, now I've done you a favor. Time for you to do one for me..." "What do you mean?!" I shouted. Runt ignored me: "Come on in, boys!" Suddenly another imp appeared next to Runt, grinning: "Wow, nice job, Runt. We'll have some fun with this one." Alarmed, I turned away to run but could only waddle a few inches away before another two imps appeared before me, grinning mischievously.
I turned back to Runt: "What are you gonna do to m--" Before I could finish, though, two of the imps leapt onto torso. Clinging to my vast lats, they both started sucking on my nipples and kneading my muscle tits. Runt must have changed my nipples somehow, because the pleasure was nearly orgasmic. My dick rose and grew to enormous size, nearly a foot wide, its head bobbing in front my own. Suddenly another one of the imps jumped onto it, rubbing his own lithe body over its surface and licking the head with an impossibly long tongue. I moaned as I felt myself on the edge of a cataclysmic orgasm, then looked down to see Runt standing before me, grinning wickedly. He then ran behind me and thrust his arm between my foot-deep ass cheeks, plunging through my hole and finally reaching my prostate, insistently tickling it. I bellowed as I spurted gallons of cum from my cock. There I stood for what seemed like an eternity, a humongous cum fountain, the imps entertaining themselves by groping and licking and teasing my colossal beefy body. I was helpless, little more than their sex toy. Runt giggled: "Having fun? Cos we are..."
