Machine Spitroasting

Mistress Sidonia is using her fucking machines in various ways to stretch her slaves orifices. She starts with single arse fucking, moves into a mechanical spitroast before using them both on his arse simultaneously, the Worlds first machine double penetration! Mistress decides to reward the slave for his suffering and attaches a cock milker, so he is wanked and fucked in the arse at the same time until he spunks in sensory overload.
