My wife has a long term lover now, he is married although a sexless marriage and they met on a swingers site. They fuck every week and all three of us get on so well. He has certainly fallen for my wife and tells her he loves her but she knows her boundaries and reminds him it's a hotwife relationship and she does it to please her husband. This is why I sometimes join in for a three some which he's fine with just so as he knows he can't always have her to himself. They've been fucking every week for nearly 2 years and can see it going on for a few more yet. She has fucked a few inbetween which he doesn't know about and will continue to do so occasionally. He is just crazy about her and gets turned on if I send him a video of her sucking my cock or videos of her with other guys as long as he thinks it's before he started seeing her. He's even offered to clean her up if I cum in her although I never do in front of him, only in her mouth. So in some ways although he's a bull he must have cuckold tendencies like me if he's turned on seeing her with others.
