I once hooked up with a girl at a party, and we ended up in the basement to have a quick fuck,when we realized we do not have a condom. Turned out that was not a big deal, since she just said "nevermind, just fuck me in the ass then". So I just pushed her forward against the wall and pulled her pants down to her ankles, pulled out my dick and started fucking her asshole. When I was about to cum I wanted to pull out and maybe cum on her ass or somewhere, but she told me to cum inside. So I did.

Afterwards she just pulled her pants back up and we went back to the party.

Fun fact about me: a lot of girls I hooked up with told me that I shoot the biggest loads of all guys they ever had. (And I know for a fact that the amount of cum I am unloading is waaaaaay above average). On top of that, I didn't cum for 3 or 4 days before I came inside the girls ass.

So back at the party she sat down somewhere talking to some people and when she stood up a moment later, she left a big wet spot (7 or 8 inches in diameter) on the couch while having the same spot on her jeans, because there was so much of m cum leaking out of her ass and threw her pants.

Everyone knew what happened to her, but no one knew it was me ;)
