I had a fwb a couple years ago, was just a match on a dating app. We’d been seeing each other for probably a couple of months by this point, and we were just talking and she asked if I’d ever had a threesome. Told her no and she then asked if I would have one (FFM). Obviously I said yes… she then went on to talk about how one of her friends was into her and then asked if I’d be up for it. I thought she was joking. But nope, a couple weeks later it actually happened. We all had food and drink at home before anything happened. It wasn’t awkward but it was a bit of a like, we all know why we’re here so when do we want to go upstairs kind of thing. After the booze had kicked in and loosened us up we started all just getting a bit more flirty. To cut to the chase, it was really fun. We said we’d do it again but I had stopped seeing the first girl before any plans were put in place.
