A lone young man, unseen by the world, retreats to his private space. His hand reaches into his pants, pulling out a thick, veiny cock that's surprisingly fat for his slim frame. He strokes it slowly, feeling the girth, imagining unseen hands joining his. His breath hitches as he picks up speed, the sound of skin slapping against skin filling the room. He's close, his cheeks flushed, and with a final grunt, he releases, hot cum spurting out, coating his hand and shirt.
