In the dimly lit, private sanctum of his room, a young man explores his deepest desires. He sits on the edge of his bed, his rigid cock throbbing with anticipation. His eyes fixate on the tiny hole at the tip, a source of both pleasure and pain. He expertly applies pressure, teasing the sensitive flesh, drawing out a bead of pre-cum. His breathing grows ragged as he intensifies the CBT, pushing his limits, before finally releasing, his hot seed coating his hand.
