Brian, the hunky stepbro, can't keep his hands off Theo, his little bro with the big dick. Theo, innocently masturbating in his room, is caught by Brian who, unable to resist, joins in. They suck each other off, their hands exploring every inch of each other's bodies. Brian then turns Theo around, admiring his ass before diving in, tongue-fucking him until Theo's moaning and begging for more. Brian stands, aligning his thick, straight cock with Theo's hungry hole. He pushes in, filling Theo completely. Theo cries out, taking Brian's length deep inside. Brian fucks him hard, their bodies slapping together, until he can't hold back any longer. He pulls out, cumming all over Theo's ass, his load dripping down Theo's balls.
