My first time. Let's call them Anne and Bianca. One evening I called Anne to see if she was free for dinner. She was already going out with Bianca but I was welcome to join them. We had a lovely meal at a waterfront restaurant and during the hot summer evening there was a definite sense of sexual tension in the air. I drove them back to Bianca’s.

On a hot summer night we sat outside appreciating the late breeze. Things changed in a funny instant when I started quite naturally massaging Bianca's shoulders. Anne said it looked very sexy. Partly for a joke, I slipped off Bianca's straps and slid her top down exposing her breasts and gently stroked them. Anne gasped with pleasure and said "Oh so now you probably want to fuck Bianca." Bianca said nothing but looked at Anne as I now gently stroked her nipples. I replied, "Well yes. Would you like to join us?" Anne looked off into the distance with glazed eyes and said, "Oh you'll probably want me to put your cock in Bianca and then into me." A little surprised by the fantasy talk, I replied, "Yes of course." Anne paused then said, "Oh fuck it. Let's do it." We all laughed. We opened a bottle of sparkling as it was all our first time. While a lot happened sexually, the best memory was the beginning. Naturally I was very erect and ready for action. Bianca was also very aroused and laid me back on the bed and mounted me. Anne was smiling as she watched Bianca riding my cock. I saw this and reached out for Anne's hand and put it on my balls. My intention was to make her feel part of the group but what she did next has stayed with me forever. Anne pulled my cock out of Bianca's cunt and sucked Bianca's juices of it and then slipped it back in. she did this a few times and all 3 of us found it very very sexy. Anne then said, "hey its my turn." as she admitted later I might come too soon for my first time with 2 women. But to be honest I was doing my best NOT to come as I wanted it to last FOREVER. What followed was nice fucking with both Anne and Bianca. Then it took a turn I was NOT expecting. I was fucking Anne while Bianca watched and she suddenly pulled my cock out of her pussy and guided it, very easily, into her arse. So I was kneeling over Anne fucking her arse. Bianca saw this and immediately dived down to lick Anne's pussy. This was the moment when I went "Duh they are bi." I was enjoying the scene and pulled out of Anne and took Bianca doggie while she licked Anne. It was a wonderful scene and of course led me to no longer be able to contain my orgasm. I pulled out of Bianca and for some reason stood up and exploded a stream of cum out of my cock all over Anne's tits and up over her face into her hair. Bianca kept diligently licking Anne. The combination of both made Anne explode to orgasm. WOW. An amazing experience and one I shall never forget.
