In the confines of their shared bathroom, a horny brother can't resist the temptation to stroke his massive, thick cock. With the door locked, he jerks off enthusiastically, his huge dick throbbing in his hand. The sound of running water from the shower next door sets the rhythm as he works himself into a frenzy. The anticipation of being caught only heightens his pleasure, and with a final, low groan, he unleashes a torrent of hot cum, coating his hand and the bathroom tiles.
