Chapter #4Big muscles, big cock. by: Chrisann   "Could you give me big muscles?" I asked sheepishly. "And maybe a little... bigger, you know... down there?"
Runt gave a cocky smile.
"Thought you were gonna say that" he said, grinning. "But why stop at a little, when you can go big"
Runt started walking towards me and I started to back step.
"Wait, what're you gonna do?"
"Don't worry, your gonna be happy with the results"
Runt extended his hand and brushed my dick through my boxers. Upon contact there was a jolt and a red spark of light, then a tingling sensation throughout my dick.
"Ahh whoa.... i feel like, like i'm gonna....cum"
And I did, right there in my boxers, I couldn't even touch my dick because of the sensations that i was having. I shot a load, then another, and another. I stopped cumming for a moment but the sensations intensified.
"Now, comes the part your gonna love" said Runt, grinning as his own cock became hard.
I noticed that my boxers were getting tighter, and as they were getting tighter i could hear a stretching sound. I looked down at my cum soaked boxer's and could see the head of my dick becoming more noticeable through the material. And with each thrust forward into the material i shot several more loads. I stumbled back and fell on to the floor propped up against a cabinet.
"Oh... fuck.... this is..." I mumbled between heavy breaths and moans, as now my dick was trapped by the material, Runt grinning and stroking his now 13 inch member. With each thrust I shot a bigger load, and these weren't little dribbles onto the floor, I was getting some air time, even with them being filtered by my boxers, that were becoming ever more painfully tight.
With each thrust you could see the slit in the head of my dick more visible, what slack that was in my boxers was now getting yanked up the crack of my ass. Another huge thrust forward and several huge volleys of cum, i could hear the boxers starting to loose over the stretching sounds of my skin. Runt standing there, leaking precum like a water hose making his own puddle on the floor.
"Are you enjoying this" asked Runt, a wide grin on his face as he started quickening his strokes."I know i am"
The thrusts continue as well as the relentless cumming, and as I was trying to tell Runt to make it stop, my boxers finally gave way to a 9 inch pole that wasn't done growing. And as this pleasurable growth continued I kept unloading more and more cum. I was hitting the ceiling with each shot that flew out of me, and each shot took at least 15 seconds to completely blow out of me.
"Runt, this is too much, i can't...."
"What, this is nothing, you'll be fine, besides i am not doing anything you didn't want"
As my dick now passed 11 inch in length I noticed that the volleys of cum were getting longer and more intense. I was starting to wonder how big he was gonna make me. My dick now passing 13 inches and shooting almost a steady stream of cum all over my ceiling, i was on the verge of blacking out when with a crack, my dick stopped lengthening leaving me with a long 15 inches.
"See that wasn't so bad, you handled that like a trooper, but you ain't done"
And with that statement the stretching sound returned as my dick started to look like it was beating with my heart. It was thickening, fairly fast as I sat there with my pole in the air watching veins worm there way under the skin increasing it's girth. finally when it had reached the girth of a pop can, it stopped.
"Wow, you weren't kidding when you said A LOT, were you" I panted, gripping my newly sized tool.
"Nope, and you know, as nice as that is we can't forget about your nuts"
"Wait what" I responded trying to think straight from the ecstasy driven growth i just experienced. Runt came walking up to me, with his dick still hard spitting precum. He grabbed the head of my dick and pushed it to the head of his, and with a firm grasp started stretching my skin on my dick, giving me foreskin i hadn't had since a baby.
"fuck....what are you doing"
"You'll see" has he commenced to jacking both our dicks off with the foreskin keeping them connected. The sensation was like nothing i ever felt before.
"And now, we fill em up"
And with that statement, Runt unloaded into our docked dicks with such a force that his cum was being forced down my dick,and into my balls. Load after load Runt shot and forced down my dick into my balls.
"Oh shiiiiittt" I cried out, as my balls started swelling in response to the force feeding. Faster they swelled as he came more, quickly filling up my sack and then stretching it, swelling past the size of baseballs , past soft ball sized, and finally stopping at cantaloupe. Runt pulled his dick from our docking as I continued to buck my hips uncontrollably.
"I gotta cum, i gotta... get it out... i am so fucking horny"
With one huge buck, I started unloading. The force so hard it started busting the sheet rock off the ceiling, and spraying almost everything in the living room. After a minute or so of cum geyser, it finally subsided to several shots and then eventually just a steady dribble, I noticed that my balls had only shrank down to about softball size,and my limping dick wasn't going back to normal. I laid there panting, quivering from the sensory overload.
"See, like i said, why settle for a little when i can give you a lot" he grined, wiping cum off of him self.
"that was insane, that was so fucking insane"
I got up off the floor, and was a little taken back but the weight of my crotch. Runt had left me with a member that was 8 inches long and 4 inches thick when i wasn't excited.
"So, what else you wanna do. I mean that was fun and all, but i could go another round or five. Doesn't make me any difference."
"Again, what did you have in mind cause that was as gay as I care to be"
"Ahh sex is sex, and besides with me it could be so much better and intense, besides, your already starting to stir some again"
Runt was right, i was already getting semi hard again. But was i turning gay or was he making me think the things I was thinking about having sex with him, or even having him change me further more.
"Okay, thats your cock sorted... now for the muscles.
