Last week I have had my first threesome

So I am 25yo male, and for like 2 years I have girlfriend and we are getting married soon.

Sex life between us is kinda slow, she for a while tought she is asexual yet, this became untrue.

Few day days ago, as part of her program with her friends, she somehow got into chat about more NSFW things and somehow it all came into that she came home with 1 of her lesbian friends.

Funny enough I made a joke about it in text that night, and than she called me with her asking :D can I come in.

Sooooo let's say everything unfolded quickly than, lesbian or not, this friend was so wild on both of us, no pussy or dick was left untreated and we switched focus from one another whole night a morning with some sleep break.

Craziest part is to me, she than stayed overnight and had a threesome cuddle too which here there ended up with more oral, fucking, fingering etc...

I was so exhausted but I could feel that even though it was such a one night stand, there was no regret from any side, and that everyone just felt secure and good...

I could go on and be more detailed, but you might ask about this if you want to hear and enjoy words of mine further.
