My (28/m) first time....(23/m & 22/f at the time)

Me and my ex gf (D) had a great sex life. We had been together for 3 years and the sex hadn't dropped off.

She was bi and as a result, we had a few fmf threesomes and she played with another woman on her own when on holiday once.

We agreed we'd try a MFM threesome and spoke about who the third could be, we both settled on my friend (G). We had dirty talk including his name for months and then G announced he was throwing a party....

The party was great, we had fun drinking and had a few lines. Eventually it was just me, D and G left. Me and D spoke and agreed that we'd give it a go and see if G was up for it.....

Me and D started kissing half naked on a sofa as G was sat on the other sofa and I asked G if he wanted a closer look at D, he laughed and said "yeah of course" and moved to our sofa, D sat in the middle of both of us.

Me and D shared a look and I nudged D and gestured that she pay G some attention and it all took off from there......

Eventually it was G's turn to fuck my gf......he entered her from behind as D had my cock in her mouth and after a couple of minutes, I stood up and sat on the other sofa and just watched them fuck...... something that we had never discussed.......

That was the start.....
