My wife is 8 years younger than me. She and I were very open sexually when we met and remain so. We both like to explore and involved other people in our sex life right from the start. It works out good for us as we both like variety and have different interests. We didn't often discuss the details of our outside fun but sometimes she likes to tell me about new experiences she has. Lately her libido seems to be exploding. She's been meeting more men and seeing them sexually. I asked her about it She says she's always thinking about the "next guy" to see what makes him tick and to see what he may introduce to her. She told me she's been seeing a guy whose very domineering. She said it's opened up a whole new sexual world for her. She showed me a video of her having an experience with him and some other woman. The women was filming. My wife was nude on on fours on a bed. The guy was nude. He had a fist full of my wife's long hair which he was forcefully pulling making her back arch and her ass stick up as he slammed her pussy with a very large dildo. He was yanking her head up with one hand and just slamming her so hard with the dildo. And she was cumming and cumming. She was cumming like I've never seen her before. The woman filming was laughing every time she came and making comments about her loving getting fucked and used. My wife was slick with sweat and not only allowing this guy to abuse her like this but loving it. We talked it out she explained that it was a big turn on for her and that she found really hard dominating sex gets her off like she never imagined. She promised she would be careful and not go "too far." Until this she had always been very sexual but in an aggressive and sensual way not in an abusing way but now she's seeing this guy regularly and she is always happy when she arrives home. I even tried to get a little aggressive with her but she didn't like it. She loves our thing and she loves that thing. She met a few more guys of that ilk and her being treated this way is her main sexual outlet outside our home. She came home with pierced nipples with rings through them which some guy had done so he could hook her up to things or whatever and she says she is really feeling good about the whole change in her sex life. I love her so I support her even though I don't really understand what she enjoys about pain and abuse.
