A man, alone with his thoughts and desires, decides to indulge in a unique form of self-pleasure. A glass cup, innocent in its daily use, becomes an object of intrigue. He caresses his penis, now rock hard with anticipation. The cup, cool and smooth, awaits. With a steady hand, he positions himself, slowly sliding his engorged member into the cup. The sensation is unlike anything he's felt before, a blend of pleasure and novelty that sends shivers down his spine.
