Tied to the chair, teased, cummed and postcum tortured

Tied to the chair, blindfolded and ballgagged. As we both like it. I could do to him anything I wanted. So, I decided to tease his cock with an electric massager, lubricate it, and tease his frenulum, clip his nipples and play with him until he cummed. But "cumshot" is not equal to "end of our play" - I teased his very sensitive cock again. He moaned a lot, especially after cum.
