The roommate's hands, already familiar with the rhythm of daily chores, now learn a new, intimate task. He grips his friend's cock, feeling its urgent throb, guiding it with a growing confidence. The room echoes with the wet sounds of his strokes, the air thick with the scent of pre-cum, as he brings his friend to the brink. With a choked groan, the cock pulses in his hand, releasing a torrent of cum that coats his fingers, a testament to his newfound skill.
