This happened about 2 years ago now. I'm very open sexually and my relationship swings. I was talking to a woman off a lifestyle site and she mentioned her and 2 friends were booking a hotel for a GB later that day, if I'd like to attend. As someone who's open, confident in his size/ abiliity and far from shy, I accepted and was invited to arrive for 7pm.

About 7:30pm I arrived to find the 3 women there alone. Apparently 4 younger guys had arrived at just before 7pm, done their business and left already. They were expecting others, but they wouldn't be there for another hour or so (3 as it turned out), so what would any self respecting man do but keep all 3 of them entertained til then!

The next few hours were spent with me bending them over or them riding my dick, while one of their friends filmed the more interesting parts. I got videos of me running a train on all 3 of them one after the other, and all 3 of them orgasming for me.

After about 3hrs, another 2 guys showed up, so we shared them between the 3 of us. I left well and truly spent, having expected a GB and got a reverse GB!
