Sex passed out
I was having sex with my wife and giving her oral. Then she got on top me putting her wet pussy on my face,virtualy sitting on my face as i licked and sucked. She was so into it she didn't realize i couldn't breathe and I passed out.
She only stopped because my tongue wasn't doing what it was before which was licking her clit.
She at first became alarmed and began tapping my face and i soon woke up.
Now she jokes she knocked me out with her pussy,even told a couple of her girlfriends I fainted during sex.
The thing is she has passed out a few times having an orgasm.
