Strung Up Machine Fuck

Mistress Sidonia is plating with her slave in the dungeon. He is wearing 6 inch heel leather boots as a form of bondage. Mistress teases his cock and strings him up in front of the mirror so he can observe his own vulnerability. She stretches his ass and then uses a big black dildo on the fucking machine to penetrate him, the remote control allowing the speed and thrust to be adjusted as she torments his nipples.
