A friendly movie night turned into a hot threesome [Group]

[This is FFF, so still ‘Group’, but there wasn’t a tag for that] About 6 months ago, I moved to a new city and was failing at making friends IRL. I used one of those apps that helps you find female friends and ended up finding a cool girl named Ashley. Ashley had been married for about a year to her wonderful wife, Kaylen. I’m also gay so we connected pretty quickly and bonded over similar stories. Ashley, who also goes by Ash, is the more “butch” one – she’s a bit taller, usually has her short blonde hair in a tight ponytail. Kaylen is very femmey, she’s got a very athletic build and long wavy brunette hair. Ashley and Kaylen are in their early thirties whereas I’m in my mid-twenties, so they kind of end up “adopting” me and taking care of me – they often buy my drinks, take me with them on planned day trips, etc. It was never anything romantic, though they knew that I was polyamorous and very sexually open.
