The one with my ex gf of 15 was an arranged rough sex GB that she knew nothing about. She thought it was just an interview for a job. Long story but everyone got what they wanted. The one with the 12 yes I did but again it was started without me there I happened to find her in a maze in a swing club wearing just a pair of heels and lots of pearl necklaces. The one with my ex wife was a adhoc session with a group of bi campers in which she got to fulfill a long time fantasy
I don't like being gang banged, personally. But my boyfriend likes watching me being used so I do it for him, The most I've ever had use me was seventeen.
He has me sport fucked about once a week by up to ten guys, but usually its five or six.
I've been GBed several times and I have to arrange with your wife. This is not to say I haven't enjoyed some of it, I have but over all I detest being gang banged/ gang raped. I only do it because my hubby enjoys watching me being sexually used and abused.
