Mary got a little wild at a house party one night, it wasn't a gang bang per se. Normally, the most she would do in one night was three - one man in a foursome with me, perhaps a single guy, and of course me. One night, she did four in an orgy-type situation.
That night at the house party, after a foursome a single guy desired her, she agreed and didn't complain when he took her into the common room. And then the chain started. We're sure she had at least eight, the total may have been a dozen or more.
On the ride home, it didn't seem much different than any other night, except she was very tired and we didn't have reclaim sex. The next day, I couldn't tell any difference as we got up and went to church. When we finally got around to talking about it later that day, she was exuberant about the experience, and when we hit the mattress in the afternoon she seemed as excited as usual.
