It started two years ago when her friend was visiting for New Years. They came up with the idea and approached me about it. Of course I said yes immediately :) It was a bit awkward (none of us had done one before) but still very fun.
Since then we’ve had 5 threesomes, and we’ve gotten much better at it. We live in NYC and her friend lives in Boston—Covid has made them a little tougher to arrange, but her friend might take a job in NYC. Fingers crossed!
