Your best friend acted quite a bit boldly when he asked your wife if she was wearing stockings, but she seemed not just very willing to allow him see by himself but also to encourage him to go for a higher prize.
As she comes out of a man's apartment, your wife is exactly what you craved her to be. She's your hotwife. She's independent and free to be with whomever she pleases and that delights her. Sex has never been better. And when she leaves a man's apartment like this with a smile denoting satisfaction and conquest you know one thing. She's leaving a very tired and satisfied man. And that turns you on as her cuck.
Few more glasses, and she will be sucking every cock in the place
