Mistress Odette needs to extract a sample from her test subject by any means. She has him strung up by his wrists, exposed and vulnerable. She makes him get erect using her soft nitric gloved hands and strokes him until he is fully and painfully erect. She uses her vibrator on his cock and rubs it back and forth, enticing him to cum, but denying him his orgasm. She places herself behind him and rubs him sensually while her pelvis grinds on his ass. She brings him closer and closer, but makes it known that he's going to have to do something for her if he is going to be allowed to cum. She makes him agree to do whatever, unspecified thing she wants him to do, just to be allowed to cum. She finally releases him, making him fill her hand with cum. But now is the time when his previous oath will cum back to haunt him. She takes her cum filled hand and shoves it into his very resistant mouth! He sputters and gags, but he must swallow all of it!
