part 1 of fixing blue balls

My roommate’s hookup had been coming around lately. Nothing between us happened since I whipped out his cock and cured his blue balls.
One night I was alone in my dorm late at night and the two of them barged in, clearly extremely drunk and horny. They started making out and groping each other, clearly not even aware that I was in the room. I’m lying in my bed, eyes wide open, watching this unfold. He grabs the back of her head while making out with her and her arms are pulling him in. He pulls down her jacket and she pulls off his.
Things are escalating very quickly, and it’s really turning me on. I spread my legs a bit and reach down and decided to enjoy my show. I rub my pussy over my panties, listening to them make out and tear each other’s clothes off.
It doesn’t take long before they are down to their underwear which is when he pushes her down on the bed and spreads her legs over his shoulders. She pulls her thong to the side and he starts pile driving my roommate. She’s screaming and moaning like there is nobody else in the entire building and his balls are just slapping against her. They’re both moaning and I start to slip my fingers inside me. I’m biting my lip trying not to make any noise but it’s really hard with my live show.
My roommate starts calling out “I’m gonna cum, I’m gonna cum” and thought “shit, so I am!”
“Yes yes yes yes” she moaned and I pushed my fingers deeper into my pussy and arched my back. As my roommate starts coming, so do I.
I gasp a little but they don’t hear me over her screaming.
Afterwards she starts telling him “stop stop, I’m so sensitive.” And he keeps trying to keep going but she makes him pull out. He clearly hasn’t come yet and I’m starting to understand why he got blue balled the first time!
They end up laying down on her bed and she passes out immediately. I can still him stirring though, it sounds like he’s stroking his dick. I’m still incredibly horny and, well, I’m sure you can guess what I did :)
