In the throes of self-discovery, a lone man explores the limits of his endurance, focusing on his sensitive testicles. He begins with gentle caresses, but as his arousal grows, so does his intensity. The soloboy grips his balls tightly, pulling and twisting, the pain morphing into pleasure. His solo ballbusting session escalates, with him striking his testicles with increasing force, his moans filling the room. His body tenses, and he hits his peak, a guttural cry escaping as his essence spills forth.
