Daddy's rough hands spread the boy's cheeks, revealing his pink, puckered hole. "You're such a dirty little thing, aren't you?" he grunts, spitting on the boy's ass and rubbing it in with his thumb. The boy whimpers, pushing back, begging for more. Daddy obliges, slamming into him, fucking him hard and deep. The boy's cries fill the room, mixed with the sound of Daddy's heavy balls slapping against him. Daddy fucks him until the boy's ass is red and raw, then pulls out, cumming all over his son's back, the boy collapsing onto the bed, spent and satisfied.
