Desaster after weeks in chastity

Looked up for me since weeks in his Chastity device my Slave is mad about his horniness, so I tease him and play a sadistic game with him, i tie him in a straight jacket and mouse gage him, then i start to wank his dick and drive his horniness with a nice pin wheel to the top. He wants to come but i want my fun, so i sit on his face and wank him again, the horny guy can now see and smell my pussy but not more cause of his gag... and to his total degradation i stop to wank him a second before he can shod his load. What a Desaster...
