In the privacy of his room, an 18-year-old boy, driven by curiosity and hormones, explores his body for the first time.

As his confidence grows, he takes his time, learning what feels best, until finally, he finds release, his body shuddering as he experiences the intense pleasure of masturbation for the first time.
