it could be human trafficking  

i hope not though
i hope it is tears of pleasure
but you said after "sex" not after 'o", so it worries me

I never asked her what that was about and she never offered an explanation. One good thing, i always knew if the O was real

I'm talking real tears too.

I was seeing a civvie girlfriend earlier this year, where one time she had a screaming orgasm during sex.  Then she basically let go, collapsed, and she started crying, then she thanked me.

I don't know what to make of it.  It wasn't the first time we'd had sex either, it was more like the 20th time.  Maybe she involuntarily let go of some emotional baggage that she was holding or something.

I never saw anything like that before or since.

I doubt that I'll ever cry after sex, but I may cry the next time I am in her presence again. The most beautiful woman I've ever met in person, and one of the sweetest as well.

it happens a lot in prison...

I had it happen with a girlfriend.  She was a virgin when she married her husband. She was still married and I was seeing her.  I started trying to give her oral and she was squeezing her legs shut.  I had to caress the inside of her thighs and tell her how wonderful she smelled down there and how pretty she was down there and really get her to relax.  When I started eating her I did really, really light strokes with my tongue.  Finally, she relaxed and had what I think was her first orgasm from oral.  She had been married about 15 years.  

This was the same woman who orgasmed with no sexual touch at all.  Just from me kissing her passionately for about 15 minutes.

I plan to travel to her state again sometime in the next few years for a booty call.  She was a lot of fun.

It happened

When the service was extremely substandard and then I realized how much money it cost me!
