Straight wife or girlfriend groped by other women

[InnocentBystanders]

A few years ago my wife and I had gone out drinking with a friend of hers. My wife is not bisexual, she states she has no interest in women at all. But that night after we got back to our house we all decided to get in the spa, naked of course. I was sitting on one side of my wife and Melanie was sitting on the other side. We continued drinking and partying and were soon all pretty f'd up. I got out to use the restroom and when I returned, I sat across from the 2 of them. they were talking and holding hands. I began to encourage them to kiss, they eventually did but there was no passion in it.

As we began to wind down, Ellen was laying back a bit in with her eyes closed. She was still talking a bit, but mostly just relaxing. Melanie was doing the same thing but would turn to face her every once in a while to make sure she was awake. One time Ellen didn't respond so Melanie reached over and squeezed her tit. Ellen laughed and squeezed Melanie's tit in return. After that, Melanie was holding Ellen's hand as they both just relaxed. I noticed Melanie was softly masturbating while sitting there. After a couple of minutes of this, she moved Ellen's hand to her pussy and began masturbating using my wife's fingers!

Ellen didn't seem to mind and eventually appeared to be doing it on her own so Melanie moved her hand over and began to play with Ellen's pussy. After a few minutes of that I saw Melanie squeeze her thighs together as she came. She then began to finger Ellen and play with her clit causing Ellen to look over at her just as she began to cum! Nothing was said after but we all decided it was bedtime. They went inside and Melanie got in bed with Ellen and me. It was a little too crowded in our queen bed, even with Melanie snuggling my naked wife, so I got up and slept on the couch. My wife claims nothing happened with them in bed together, but I'm not sure I believe it though.
