This is something of mix between a TIFU and TIL.
But as I doubt either of those forums would welcome it I’ll share my sordid story here.
Before I start though. I know that there is a spectrum of how often/easily girls can cum, but I’m definitely more than most but less than others (based on girl talk with friends and limited porn watching). If I’m in a horny/bored mood I can masturbate well into double digits no problem, and on average during sex I’ll have maybe 4 to 6 typically. Not bragging, just relevant data.
Also relevant to point out that in my admittedly limited experience with guys (3 bfs and 1 one-night stand) I have only been with guys who are in the ‘one and done’ camp. There was one bf who could sometimes cum twice in a session but it was rare for him.
Alright, so that said, last weekend I was invited with a gf over to a house party. She and I had just come back from a week camping and I was looking forward to a night alone to have a long bath and get cleaned up etc. But the house belonged to a stupidly rich friend of hers and it had a huge pool and hot tub and seemed like a fun so we went.
