Wife asks trans to fuck her husband

She knew that she was her husband's best friend, however she didn't suspect that they knew each other for so long, when she was really him, so when her husband told her about the possibility of a threesome, she didn't suspect his hidden intentions. It took her some time to accept the idea of being with another person but she accepted. Being herself the one who went to talk it over with the girl, she was already aware of her friend's desire and so it didn't take her long to accept. When the expected day arrived, the wife immediately noticed the true nature of her husband's friend.
