In a cramped, dimly lit room, two schoolboy brothers, their uniforms disheveled, explore the taboo. They tentatively touch each other, their breaths hitching as they grow harder. One brother timidly takes the other's cock into his mouth, swirling his tongue around the head before taking it deep. They switch, the dominant brother pushing his cock into his sibling's tight hole, fucking him gently at first, then harder, until they both explode, their cum mingling on the floor.
