In the privacy of his room, a curious young man explores his bi-sexual desires, caressing his body and imagining a partner. He teases his ass with his fingers, pushing them in and out, moaning softly. His mind races with images of a lover penetrating him deeply. He slips on a pair of lacy panties, feeling the fabric against his skin, and adds a soiled diaper and tampon for extra sensation. He jerks off furiously, his hard cock aching for release, until he finally cums, his load staining the diaper.
