It was early evening and Ruby and I were getting prepared for an evening we had been both looking forward to for a long time.
We had met another couple on a swingers night at a sex club, and we had a little fun with them in some parallel play and watching each other have sex, but hadn't done anything together.
Anyway, at the end of the night, we exchanged numbers and had been chatting for a couple of weeks, and had finally agreed to meet up at our place for some drinks and to see where the night went, but we had all said no guarantees and if any one of the four of us felt uncomfortable we wouldn't go through with it.
This was going to be our first ever foursome and the first time either of us had been with someone of the same sex. We'd both fantasised about this for a long time and we chose a bi couple for this exact reason. So we could all enjoy having fun with each other.
So Peter & Claire came over and we just chilled for a bit and had some drinks to loosen ourselves up a little.
After a while Peter & I went to get the girls a couple of drinks and when we returned they were busy kissing and getting it on. This was super hot, to walk in on the girls like this, so we took them their drinks and put them on the side and watched them go at each other for a while. And, it wasn't long before it started to get heated. Ruby started to take off Claire's dress and just threw her down and started to go down on her. She started to moan loudly, and was holding Ruby in place and grinding on her face harder and harder.
This got Peter and I feeling all hot and horny and while all this was going on I started to rub Peter's cock in his pants and I could feel that it was growing, so I asked if it was uncomfortable and would he like me to get him out of his pants. I undid his fly and as I let out his semi-hard cock, he groaned with pleasure of what he knew was to come. I got on my knees in front of him and just took it all in my mouth, and felt it grow to its full length as I took more and more of his shaft.
