Lonely and horny, the unidentified brother retreats to his private space, stripping off his clothes to reveal his impressive, throbbing erection. With a hungry groan, he wraps his large hand around his massive cock, stroking it slowly at first, building anticipation. His breath quickens as he increases his pace, his balls tightening with pleasure. Pre-cum glistens at the tip, and he leans in to taste it, sending electric shocks through his body. He continues his relentless jacking, his muscles tensing as he approaches climax, finally exploding in a torrent of hot cum that coats his hand and drips onto the floor.
