So yea yesterday my buddy wanted me to have a threesome with him and his girl since him and her are in an open relationship I'm a 6'3 average build kind of guy and I've never had a threesome so I was kinda weirded out but decided to go through with it and well I don't know how to feel now So I get to the apartment a few hours before she comes back from work so me and my buddy are chilling around until she comes home and when she does it's a lil awkward because of social anxiety but my buddy helps us relax and after a but of chatting we go for it Now I'm not the biggest guy by any means but compared to my buddy I dwarf him sixe and thickness now his girl had never had bigger then him so when I first entered she came instantly and I made her cum a few more times We would switch out with one of us fucking her while the other either sucked on her tits or made out with her and this went on for a few hours and we finally finish when she told us she was tired but I was the only one who hadn't came but I was fine with it So we clean up and I go home I get a text a few hours later and she said she wants to meet up at my place and have a one on one session without him and I know it isn't technically cheating since it's an open relationship but I mean It's what she said that makes me think it is She texts me saying I'm the biggest she's ever had and that she wants my cock more than anything thst her bf doesn't compare to me ect and I'm stuck between letting her come over or not but I figured why not ask all of you and get your input on the whole thing
