Mistress Sidonia is a sexy blonde mistress who also has an interest in science. Today she is experimenting with milking; after all, men have nipples, who says that you can’t extract a little milk out of them? She binds and gags her subject, tying him to her chair to ensure he cannot escape her grasp. She spreads his leg and gives his dick a nice hard thwack, getting this english tension started. He moans in his place and she gives him a shot before hooking him up to her fancy machine to see what she can get out of him.
