In Part 1 we join the oh so beautiful Mistress Vixen in a medical mood, she is dressed in a stunning nurses outfit and playing with Her sounds. She has her slave lay naked apart from from the chastity cage he is wearing. Mistress Vixen sits on the slaves face as she clamps his nipples. Eventually his cage is removed, Mistress Vixen sits astride his legs and generously massages some lube into his cock which of course makes him hard. The hard cold metal sounds begin to probe deeply, starting with the thin ones but soon the size starts to increase.
