In the privacy of his room, a young man indulges in a solo session with his sex doll. He mounts the doll from behind, his hips moving in a rhythm as old as time. The doll's realistic feel and tightness send waves of pleasure through him. He grips the doll's hips, his fingers digging in as he picks up the pace, his breath coming in ragged gasps. His body tenses, and with a final thrust, he finds his release, collapsing onto the doll's back, spent.
