What did my partner just do?

[u/OkTough6333]

So yesterday me (M22) & my gf (F21) were having sex. usually when we do it, we routinely do it in the missionary position and i usually finish and she’s able to have a good time too, but yesterday something unusual happened. As I was thrusting, I was having difficulty finishing – which is not common, since I usually am able to finish with no problem; but yesterday it just wasn’t clicking for some reason and I was thrusting for like 10-15 minutes. Then as I was continuing thrusting, all of a sudden I feel an enormous heavy pressure on my penis – the feeling was so heavy that, it was as if my Penis was being squeezed from all sides. With this enormous pressure on me I was finally at last able to finish & it was one of the best feelings ever. I looked over at my gf and I asked her what the hell just happened? & she just laughed and said “magic”

I’m still confused on what happened even after a day just passed since. Because we've been doing missionary for so long and nothing like this has ever happened. What do you guys think?

I'm reading this to mean you have previously not brought her to orgasm through PIV; is that right? But she tells you, "I had a good time"?

If that's the case, then what you felt was her orgasming from PIV. That often makes the muscles around the vagina contract and squeeze the penis.

You should ask her: "Was that an orgasm?", "Have I made you orgasm through PIV before?". She might be too embarrassed to tell you that you haven't before, but hopefully you guys can have a more open conversation then just, "it was magic" ✨
