We had been to a few swing clubs and had some soft interactions on the dance floor. One night at a vanilla party after everyone had left, Diane and the hostess ended up on the bed together and did some heavy petting, no oral. Diane loved it and her curiosity was not only peaked, but had to be satisfied.
We fantasized about different scenarios and a couple more times at the club where Diane did some sexy dancing with another woman, but we still hadn't fulfilled her goal of complete give and take with another woman.
We had gone to one house party where we satisfied our exhibitionist fantasy of fucking in front of other people. Those same hosts were throwing another one and we decided to go.
The party was really hot. Lots of sexy couples. One couple that showed up were an older more experienced couple than us, Stu and Angela. Stu was a charming handsome guy and Angela was a cute little dynamo of a blonde with a killer body. We spent a couple of hours on the periphery of the dance floor in the rec room, just chatting and laughing. After a while Stu and Angela wandered off to check out the hot tub outside.
Diane leaned into me and said, "Angela is really turning me on. Maybe tonight is the night."
That's the only encouragement I needed. I turned Diane towards the door and we walked out to the hot tub area. We found Stu and Angela engaged in a pretty tight conversation with another couple. Not to be foiled, I leaned in towards Stu and whispered to him, Diane and I would be honoured to have them join us upstairs. Stu's eyebrows went up and he introduced us to their new friends, apparently a couple they had partied with before. Stu then whispered back to me, give us a moment, I'm sure Angela would love that and that they'll meet us upstairs.
I told Diane what Stu said and she grabbed my hand and together we walked back into the house and up to the top floor and found an empty bedroom. Leaving the door open, I sat at the foot of the bed and brought Diane in to stand between my legs. My hands ran up and down her legs and I caressed the outside of her panties. Then I stuck two fingers inside the outer edge and slid into a dripping wet pussy.
"I was going to ask you if you were ready, but this tells me you are more than ready to get fucked by Angela. You are going to have your first woman"
