Patricia MedicalySado & Pou Fosc & Anna in Sexual Labor – KINK

I punish the boy-slave and the lady-slave with involuntary sexual labour. I make them have sexual relations without rest. My aim is to find out the sexual abilities of the boy-slave and the lady-slave; find out how long he can hold out an erection without having an orgasm, only working on his member. I do the same with the lady-slave, measuring her endurance and counting the number of orgasms she has while she straddles the boy-slave. Finally, I masturbate the boy-slave, bringing him to an intense and pleasurable orgasm after a hard day's work.
