In the privacy of his room, a twink, dressed in a full diaper, gives in to his urges. He begins to rub his crotch, feeling the sensation of the filled diaper against his growing erection. His strokes become more rhythmic, his hips bucking as he humps his hand, lost in the pleasure of the moment. The friction builds, his breath coming in short gasps, until he can no longer hold back. His body tenses, and he cums, filling the diaper with his warm, sticky seed, a satisfied grin spreading across his face.
