I was helpless against Joey's incredibly large and hairy body. He pinned me to the wall before rubbing his heavy dick against my now child sized boner - was penis was dwarfed by Joey's. As Joey's rough penis rubbed against my sensitive nub of a penis, I felt a warm sensation come from it and spread to my balls. Right before my eyes, I saw my erection re-grow to as a result of Joey's stimulation. I moaned in pleasure as my dick grew far more sensitive than I remembered.
"There we go" Joey said in a rough baritone voice. My penis slowly grew larger, 3inches....5inches...7inches....
Finally, my dick was a mirror replica of Joey's 11 inch cock - same veins and everything. My mind was clouded by the sensations given off by my new dick. My balls were also just as large and hairy as Joey's, hanging well below my legs and as large as small apples. My new dick and balls looks comedic on my puny body; I looked like a 13 year old with a 11 inch hairy man meat attached to him.
"Go ahead, jack it and grow as big as me now!" Joey laughed, leaving me to my new dick. I wanted to resist and stay as close to normal as I could. However deep in my mind, I wanted to become a hulking hairy beast like Joey now was.
