I'm normal looking guy from the outside but I've had this kink I guess for as long as I can remember but it wasn't until my now ex that I truly realised it. All my ex girlfriends ended up cheating on me but my ex was different she continually cheated on me for years and I knew all along but never said anything to her about it or let on that I knew because I liked her doing it. I always knew. She worked at a hotel doing functions and at the end of the night she would always go back to one of the guests rooms. When she'd get home she'd tell me it went late or there was a lot to clean up or something like that but I knew in reality she went and fucked one of the guys there that night. It all really became clear to me when we moved back to our home state and I went back to farming we had a house on the farm less than a km from the managers house it wasn't long before she started fucking my manager (who was also married) they would fuck pretty much every day I'd get sent off somewhere or be at the other end of the farm and he'd go to my house and they'd have sex on our bed with his wife not even a km away. He would always tell me about this "girl" he was fucking that she'd come out to him in the paddock somewhere and he'd fuck her in the tractor but I knew it was my ex he was talking about. I would always be so unbelievably turned on by it I'd always have a hard on. She got so careless towards the end that she'd hardly even try to hide her cum stained thongs, I'd find them all the time. I loved the thought that they were fucking and his wife had no idea. She even started fucking her highschool boyfriend at the same time. Anyway that's when I truly realised how much I liked it. When I got with my now fiance I told her every little thing about me and as it turned out she admitted that she likes "variety" as she puts it in guys so she would go hook up with guys every now and then but not lie and sneak around. For the last two years now she's had a boyfriend who she sees (fucks) a few times a week. Two months ago she spent a week in a hotel with him even which is all just fine with me 😊
