My slave is on placed with purpose atop my bondage chair, kept in position in leather belts. Underneath him is a fucking machine, set up perfectly with the dildo attachment already inside his ass. Today, he is going to be fucked hard and fast by the never-tiring strong piston pump arm of the fucking machine whilst I watch, tease and encourage him. Once he has filled up his chastity cage with his engorged cock, I unlock it and begin to edge him with my bare hand, informing him that he is allowed to cum but only whilst his ass is being ravaged by cock.
