Mistress Lexi has forbidden her slave to have normal sex; instead, he can only have sex with her boots. Lexi orders him to kiss her latex clad ass while she strokes his cock to get it hard. She places his cock between her boots and orders him to fuck them. When the slave begs for release, Lexi grants the request, but after he cums, tells him he must clean up her boots. Every reward has its cost, after all.
