For sure you remember "Sister In Law" in which the cuckold guy is seduced and humiliated by his wife's dominant sister.

His wife has no shame to cheat him with her attractive and young fitness trainer. Little hubbie is good just for paying her sexy clothes and her expensive lifestyle.

A natural born submissive cuckold sissy, the perfect toy for every dominant woman like his sister in law.

This very attractive brunette calls him one afternoon. She orders him to dress up in stockings and in his wife's lingerie, as she is going to visit him.

She arrives. She towers him, wearing an amazing latex catsuit with thigh boots. He is annihilated by her presence and cannot help obeying her, even if she degrades him forcing him to lick her rubber ass.

After some face sitting she begins to train him with huge butt plugs, to have him ready for her next strap on visit.
