ok... here is one of mine. It's not the worst thing for me, but it was for my buddy!
Myself and two other guy friends (one is his step son) and one of my female slutty friends are out for the evening.
About 1am we all head back to my place for some drinks before heading home.
One of the other guys asks her to show us her breasts. She said she will if we take off all our shirts. We do.
2 minutes later she is laying on my sofa topless with one nipple in my mouth and the other in the step sons with my buddy removing her jeans (Ever sucked on nipples with another dude? There is an invisible line that you don't cross. You each have your own boob and you don't share!)
Friend is now attempting to fuck her but can't because he's had some E and can't get it up. He's slapping his dick saying "come on baby, don't be shy"
Eventually he gets it up and starts fucking her. He eventually can't cum and get's tired. It's now the step sons turn to fuck her whilst my friend starts receiving a BJ.
Step son is done in a few minutes.
What do I do? Well being that she has just been fucked and I know she has fucked at least 150 guys. I really like my dick and don't want it to fall off.
Therefore whats a guy to do? Blow your load all over her tits, then rub it all in. So that's what I did.
Step son and I go grab a beer, sit back and watch my friend try to fuck the chick missionary style on the sofa.
Very soon the cum has dried up, leaving no visible trace.
Friend is fucking her and getting all crazy. Starts to suck on her nipples with lots of good licking and tongue motion.
Step son and I look at each other and laugh!
I say "so... buddy... you do realize you're licking all my cum of her nipples right?"
He almost hurled on my sofa. He made us swear we would never tell anyone. I still haven't, nobody knows his name is Jack.
