Tied to the chair and slowly teased until cum

Tied to the chair - his collared neck to it's back, hands to armrests and legs to the base. Ballgag in his mouth, his eyes blindfolded, his nipples clipped. He can't run away. It all makes his cock very, very hard. Now, he only depends on me. I teased him for almost 14 minutes. My mouth moving around his glans, my fingers teasing his frenulum, electric massager vibrating strongly. When I ended teasing him, he cummed so easily! But cumshot doesn't mean our play is over! Do you know how sensitive penis is after releasing the load? Yes, I teased him even more at the end...
