After lying on the bed for a few minutes, he absently started to touch his dick, toying with it like if it's a pet or so. He put his fingers on his tip and followed the line of his slit. Precum started to come up.
"It doesn't feel too bad.." He said while he rubbed his chest with his precum covered hand. "It feels nice actually."
He used his free hand to hold his egg size testicles, squeezing them like rubber balls. He moaned in pleasure, and he kept doing it because he liked the pain feeling on his grown body.
Meanwhile, his other hand had instinctively started to jack off his fat dick pulling up and down his tight foreskin in the process.
"Ooh ooh aah!!" He shouted between moans as he kept doing it for a while. The bed was squeaking like crazy as it was struggling with the heavy weight of the big man above it.
"I'm a kid! No.. I'm a man! A beast man!!" He shouted while he pull off a big amount of pubes from his crotch and smelled the musky smell emanating from them. It hurt like nothing else he had felt before but he liked it.
"Fuuuuuck!!!" He screamed while he arrived to his climax and his first load of cum came out from his dick slit like a powerful stream to the pelt on his chest.
"Hey kid! I have your clothes." Erick said as he entered in the bedroom, in the exact moment that Fredrick was shooting his first dose of manmilk. He just grinned and said. "Now you're acting like a man."
