[MMF] Cabin trip ended up in a threesome with my wife and our friend

So my wife Ellie and I (M29, F27) were sad we couldn’t go travelling this summer like we usually do, for obvious reasons. We still wanted to do something, and we found a place that rented out cabins on a camping site so we rented one for a week in August. At first we were going to go by ourselves but then we got to talking with one of our friends, Nick (M28), and invited him to come along. There wasn’t a lot to do, mostly go swimming and hiking and stuff like that. We’re all fairly fit and enjoy that type of stuff though, so it sounded good to us. We wanted to party a little though so we brought booze and weed.

The first few days were nice but pretty uneventful. We were pretty much the only ones staying at the camping site so we could ignore the usual rules about keeping quiet after 11PM. On the third evening, we got in the mood to party. Drinks were had, joints were smoked and we had brought a portable speaker so we had music too.
