We haven't watched Little Bill, but my wife was so wet when we fucked after Boogie Nights it felt how I imagine it might feel after she had fucked someone else. I told her that while we were fucking and she moaned louder than ever.
I hope my wife thinks about other guys she has fucked and their cum running out of her pussy. I know I think about it, but when I ask her if she thinks about them she always denies it.
