As Dave rubbed his jock body with the soaked jockstrap, he felt himself growing even more. His feet had already swollen to size 18, way to big to fit in any normal shoe. Suddenly, Dave remembered that his brother, Kyle, was home.
Kyle is a year older than Dave, and built like a real man. He is 6'3, with a gorgeously tan and extremely muscular body. Dave runs up to Kyle's room, his giant 12 inch penis flopping up and down, and finds Kyle jacking off his measly 8 inches. Without saying a word, Dave grabs Kyle, bends him over in front of him.
"Suck my feet you fucking slut", says Dave
Kyle wordlessly begins licking Dave's still growing size 20 feet,and as Dave reaches his climax, Kyle's growing tongue licks faster and faster, addicted to Dave's sexy musk.
As Dave cums gallons all over Kyles body, he notices Kyle turning white, the same color as the jockstrap he stepped in!
Kyle is turning into Dave's...
