Mistress Nana lets a masochist masturbate and watches it.
The masochist is made to lie on the floor and is made to masturbate while the mistress steps on his face with her feet.
The mistress helps the masochist man by accusing him of his cock with a hitachi.
When the mistress maximizes the power of hitachi, the masochist twists his body.
When the masochist man is about to cum during a handjob, the mistress takes her hand away and repeatedly stops him, teasing him.
