One of my ex girlfriends did that to me.
I am sure, till date she doesn’t know about it.
She thought I was drunk and asleep.
While I was drunk but not asleep.
I noticed her getting fondled from behind by one of her friends, who was staying over after the Christmas party.
I heard her muffled moans.
There were wet noises of the dick moving in and out of the pussy.
He didn’t last long. They stopped soon and adjusted their clothes while lying under the quilt.
It felt like watching a horror movie.
Which scared you and excited you at the same time to keep watching it.
I wanted to fuck her later that night.
But didn’t really want to fuck her cum filled pussy.
Also, weirdly enough, I came.

Maybe you found a new kink
Trust me fucking a woman who is full of someone else’s cum is very intense.
