Debbie and I had been lovers for several months. In her early 60s she came to town on a regular basis and we always spent time fucking. 

One time we were laying naked cuddling after a fuck and Debbie said she had never been with another woman and wondered what it would be like. I had a couple I played with occasionally, Steve and Kirsty who weren’t active swingers but enjoyed a 3some from time to time to spice things up. I said to Debbie I might be able to arrange that for you and told her about the 2 of them and surprisingly she said we could always have a 4some, it’d be a shame for you guys to miss out. I said if you are sure I will see what I can arrange.

Her next trip to town it was arranged that Steve and Kirsty would take an afternoon off work and I would sort my work so we could all get together. We arranged to meet at Debbie’s motel, I went a bit earlier to make sure she was still comfortable with everything.  Steve and Kirsty arrived about 15 mins later and it wasn’t long before Debbie was right at ease and really into it. Kirsty broke the ice and started kissing her and before long they were both naked on the bed, Debbie on her back and Kirsty eating her pussy before they swapped around, Steve and I enjoying the show they were putting on. After a while we stripped naked and joined in, taking turns fucking both ladies before Debbie had yet another first, taking us both in a dp. She had been sitting on Steve’s cock when I entered her from behind, slipping my cock into her ass and filling her with my hot seed. Both ladies had cum so many times across the session and Steve finished off in his wife’s mouth, only to watch her kiss Debbie with a mouth full of his cum. Such a turn on. 

After they left Debbie and I fucked again, she was so turned on by her first bi experience she just kept cumming repeatedly.
