Party of epic insanity

Ok so here's a crazy story:
So I come home here from Houston to visit everyone. Awesome time. I loved hanging out with everyone and had a great time at the party on Saturday night. However, after the party ended the craziest shit ever happened.
So I'm laying in bed with Melissa, in the midst of falling asleep, and I start to hear the sounds of some sexytime going on. I assumed it was Mel's roommate Amanda and the guy she was hanging out with earlier that night. However, then I realized that it wasn't coming from Amanda's room. It was closer than that.
I walk out Melissa's bedroom door, and I notice two things. One: The bathroom door is ajar. Two: I hear the following thing being said from behind said door: "Baby, your pussy is so sweet".
...
...
Eww.
So a minute later this girl (who was a random person who had shown up to the party but no one really knew) came out completely naked. And this girl was not real attractive. Her fatrolls had fatrolls.
...
...
Eww.
I proceed to say "Seriously?" and she backs into the bathroom. I assume they were putting their clothes back on while I walked back into Mel's bathroom to tell her what i saw. I walk back out, and this girl is sitting on her boyfriend's lap, with his pants around his ankles, on a chair out in the living room. I think they were still having sex. Not sure though. I kicked them out.

We found out in the five minutes following their departure that they had actually been having sex in the laundry room first, then moved to the bathtub. They also ripped Melissa's shower curtain off, which made her really mad because it is a really nice shower curtain.

WHO THE HELL DOES THAT KINDA SHIT?? They were HAVING SEX in a STRANGER'S BATHTUB!!!!!!!

Really messed up man. That's all I got right now.
