Yea I can relate. We do it with a guy we know semi regularly and it's a huge turn on for all of us. I like watching him do her, he likes watching me, she likes us watching. She gets more turned on as we swap out.Watching your missus get fucked by another guy is amazing, nothing compares to the feeling. Can't wait until the next one which should be Friday. Everyone should try it
She's horny as fuck for days after. It's good stuuf.
