Mistress Nastya handcuffs her slave and after getting full control over his body and his dick starts teasing his dick furiously. She has a lot of possibilities to do that: masturbating the slave's dick with a hand, gently sucking on the dick, making a rough blowjob, but denying the slave's orgasm during that. The Mistress leads the slave to the very edge with her petting and then she stops caressing him not letting him cum. And then she starts teasing her slave again, making him agonize powerless in his desire to satisfy his passion and cum.
