Got naked around my gf and her flatmates before fucking my gf.
For context, My gf lives in an old house with her sister and her sister's girlfriend (who is trans). I've met them all before but after hitting the 6month point they've been more cozy and chill and recently I got invited to their "clothing optional" evenings.
For a bit more context my gf's family is a bit of a nudist, before this point I never really saw her or her housemates fully naked but people would always be kind of chill with clothes being kind of loose. This though, was something of a "You're cool, come join with us while we get drunk" sort of offer. They were totally cool if I didn't want to strip but my gf told me that most nights they don't really wear that many clothes at all if they wear anything.
Sure enough the night us it took them all about 25 minutes to all the be naked, the first one being my gf's sister and the last being her sister's gf who double and triple checked if I was cool with her being naked due to her being trans and having a dick.
I had taken off my shirt at that time but still kept my shorts on since I still did feel a bit akward and to be honest aroused and trying to hide my erection via the shorts.
Anyway we kept talking and having a fun night. Her sister has been into that game of thrones spin off so I got to see the ending out of context. We played card games, and I got my first tarot reading. After some amount of time I neutralize and work up the chaos to slip out of my shorts and boxers. I'm not fully naked to everyone.
They all gave me a short little round of applause and my gf is getting more and more flirty with me from this point onward. To reciprocate I guess her sister starts getting the same with her gf and eventually we get to the point we are both getting erect again. I think my gf's sister notices the vibe in the room and basically says "we'll I think I'm off with [her gf's name] , thanks for hanging out? Do you guys need anything before we go? condoms?" And at the kinda casual mention of condoms I really blushed hard. I brought some but decide to go and ask for one anyway because in some way getting one from her sister was really hot.
Anyway after getting the condom and going back to her room we get to it. During her dirty talk to get me ready she keeps talking about the evening and if I found anyone hot and like I can't lie everyone was hot. I can kind of hear them making noise too which was also really a turn on if a bit intimidating because we were not going at their pace. I asked if they were always that loud after and my gf just chuckled and said she just learns to ignore it.
Anyway the evening goes otherwise normally for us getting together and in the morning after everyone is pretty chill. Naked, but not as flirty as things got the other night. They checked in with me to see how I felt and I had to keep saying I was totally cool with everything. They invited me back and I think I will keep going to these.
