This will be a tough time for this slave. His arms are tied to the side, his legs to a spreader and his head is covered with a mask. But this silence is only short-lived as the mistress enters the room and immediately starts making his cock hard. With every stroke he is getting bigger and bigger and to keep this way, she starts sticking metal rings to his cock. One after the other and even though this cock is quite big, she takes another one almost having half the length of it covered in tight metal rings. That's what she wants: a hard cock that couldn't get small again, and she starts right away to fuck him with his cock, mixed with sucking and jerking again and again. And if it seems he will cum, she is caning his cock to get him back a little bit; finally making him orgasm after a long, hard session. But even after he's orgasmed, she doesn't stop and sucks his cock head post-orgasm, what a torment.
