<human>: Can you condense the text into a few key points?

So today I was sexiled from my dorm. While my roommate was fucking I went to a study lounge to do homework on my laptop. About an hour later I my laptop dies so I go up to the dorm to get my charger. 

Again, it had been an hour so I figured they'd probably be done by now. I opened the door and see them naked on their bed having sex. Instead of leaving immediately, I try to play it cool and act like it's no big deal. I say, "I just need to get my charger for my laptop." 

Now I start to walk in the room. After a few steps tho, I freeze. I realize that I can't just act like nothing is going on; two people are fucking literally less than 10 feet from me. After a few seconds of just standing there, the girl frantically says, "Dude!" Realizing I've made the situation worse I say sorry and leave the room. I never did get the charger too so that sucked.
<bot>: I walk in on my roommate having sex and stay in the room in order to play it cool. This fails miserably.
