So i'm going home for the summer and this is the situation My friend has this gf and she is very open sexually but a little crazy (and i don't mean in bed). I'll try to explain the sitatuion as best as I can: My friend and his gf are going out and as best as I can put it are in an open relationship. This girl slept with a common friend of ours so he can lose his virginity. The weird thing is that her bf set this up. They went through with this, but it got really complicated. Her bf didn't want her to go through with it in the end, but didn't say anything and it happened. The guy she slept with thinks he can now get sex with her on a regular basis and her bf thinks its a one time thing. Now I got in major trouble because I found out about this and being a little nosey asked some questions from the bf (i'm friends with the bf and the guy she sleptwith). The guy she sleptwith found out I knew before he told me and aksed some questions and we had a huge argument about this. Anyways this girl has fucked things up with my friends and I really resent this. Now for the summer she wants to see my dick cuse my friends told her how big I am 8 inches hard. She also has mentioned having a threesome or foursome with my friends. I would be intrested in doing this and exploring my sexuality BUT last time she had sex with my friend things got really complicated. Anyways I was wondering should I go through with this or is it to risky?
