Matt's little cock was stiff as a board as he stared, salivating at the sight of his brothers thick dripping dick. He dropped his tall, skinny & hairless body to the floor, moistening his lips as he brother stepped forward.
"I knew you would see it my way."
Matt licked the tip, trying to hold back a moan before pushing his mouth over upon it, pushing as far as he could, his nose tickled by Jason's thick pubes. He began to bob back and forth on the cock, placing his hands around Jason's thighs, feeling the thick hairs on his ass as his own dick began to jump with orgasm, but shooting blanks.
"Oh yeah, fuck yeah, that feels so good! I don't ever want to be a kid again! AHHH!" Jason yelled as Matt deep throated him, pushing his inexperienced body over the top, his balls pulling against his bod, his cock starting to spew.
Matt sucked down every drop, making sure to get it all before falling back, his own dick jerking in pleasure. He moaned as his cock shot dry, his balls all of a sudden getting larger, a few pubes growing in, his dick growing an inch as a single rope of cum shot out onto his stomach causing a few hairs to grow around his navel.
Matt collapsed onto the floor in post orgasmic bliss. Jason smiled as he looked at his bro, the light hairs under his arms, the soft pubes, small member, slightly protruding adam's apple. He knew Matt was probably going to need a fore more doses before he was back to normal again.
