I am a 25 single straight man and I am very close friends with this 50 year old couple, I suspect they are swingers and maybe interested in a threesome (which I would be open to), but not sure, or even if they are swingers. He and I talk a lot about sexual stuff as most friends do, she is kind of a flirt in general, but she likes flirting with me. I know for a fact that several of their friends are swingers, he told me one time about one couple ( that they have gone on vacation with and hung out with a lot) while he and I were driving alone. He told me about how he used to fuck the guy’s wife when they were in high school, and how they were swingers, me not wanting him to think I was weird , acted like I thought that was weird, he acted strange with that conversation. There is this one friend of theirs who is also married and lives in another town, comes and visits them alone and stays in their guest house, he has a house close by. This friend is kind of flirty with her, calls her babe etc. , one night the three of them and I had been out partying and she went home early, he kept saying he had to get back and “look at something “ we all got back to the house and she was laying in the recliner watching tv naked with a blanket covering her and the lights out , the friend walked in like it was nothing and was talking to her while her husband and I were outside talking, later he brought it up and said “ remember she was asleep when we got home”. He kept telling me he had to go to bed and trying to get me to leave. Also that night he and I were jokingly talking about 2 hot girls from the party and how we’d like to get in on a threesome with them, I said I got dibs on the taller one, you can have the shorter one, and he said “ you can have them both, I just want to watch. What would you do if they started beating you up and tied you up?” His wife is very hot and I have had a crush on her since we met but felt bad about it as he and I are good friends. She likes to flirt with me and use innuendos and talk about sex, when he’s around or not. One time she told me out of the blue that he was in the doghouse because she was cleaning and he said that he imagined her in a maid outfit, she said “ that’s not funny “ and I laughed. Another time him , her and I were together and I made a joke about her calling us ugly, she said “ neither one of you are ugly, you’re both good looking “. She has said stuff to me like “ I need to cook you dinner sometime “ Once I got my Wi-Fi set up at my new house and she said “good now you can watch stuff at night “ then paused and looked at me. He has said that I need to go with them in their rv some time. He said one time that he dressed up as Hugh Hefner for Halloween and she and one of her female friends went with him as playboy bunnies. We will all be together and she’ll say something sexual and then act embarrassed. Over all they seem very secure in their relationship and not worried about each other, she’s even said that they are sole mates. They also have a hot tub. Do you all think that I’m imagining things, maybe they aren’t even swingers? I’m afraid to bring it up cause I’m not sure and don’t want to ruin our friendship as we are very close friends. How can I find out?
