In the privacy of his room, a young man begins his forbidden ritual. His eyes locked on his reflection, he slowly unzips, freeing his throbbing cock. He strokes it tentatively at first, then with increasing fervor. His other hand explores his body, pinching nipples, caressing abs, until it finds its way to his balls. He cups them, feeling their weight, before sliding his fingers back to spread his ass cheeks. He teases his hole, gasping at the sensation, as his cock leaks pre-cum. His rhythm intensifies, his breath ragged, until he can't hold back any longer. He grunts, his body tensing as he spurts hot cum onto the mirror, leaving a glistening trail of his sin.
