Roommate's Sloppy Seconds part 3.2

So I had just tiptoed into bed, my roommate and her boy toy are in the bed next to me. My dress on the floor, my morals half a mile back in the SUV. I take a quiet deep breathe, close my eyes, and fall asleep. Apparently it was so late that it was almost morning.

I woke up to the shower running and looked over. I saw my roommate's fling on the bed and realized she was in the shower. I turn over, but this man crawls into bed next to me. I was surprised, but welcoming. "What's up?" I asked. He said "Guess who blue balled me last night, AGAIN." "No way," I said, "that sucks." He starts grabbing me and I realize he wants to fuck me. I say "She's in the shower, dude this isn't the best time." And he said that he'll make it quick...

I was so tired I didn't have the energy to fight him and just kind of sighed. I'm turned away from him, on my side, ass pointed at him. He pulls my hips towards him and I just keep laying there. He pulls down my thong and proclaims how wet I am. My eyebrows furrowed because I was most certainly not wet. 

After a moment of fumbling I felt his hard cock pushing against me. I'm hungover, possibly still drunk, dehydrated, and tired so I do absolutely nothing lol. He starts pushing into me and he just glides right in. He mentions again how wet I am and I am confused.

But when he slides all the way inside me and his balls touch my thigh, I realize why he found it so easy. He was using another man's cum as lube....

The moment I realize this, the entirety of his cock was engulfed by my pussy and I moan out loud so loudly that I cover my mouth with my hand. He thought it had to do with his member, and whispered "oh you liked that didn't you!" I kept my hand over my mouth in shock as he starts quickly fucking me. I feel the cum in my pussy sloshing around and covering this man's dick. I start moaning but it's muffled by my hand.

We hear the shower turn off and man uses it as an opportunity to cum as quickly as he can. He quietly but quickly starts speed fucking me and then taps my ass as if to say "I'm gonna cum." He buries his dick inside me and unloads. I feel his cum spraying inside me and it feels really good. My eyes roll back and I even start to cum a little.

He quickly gets up and quietly returns to bed. I cover myself with my sheets again and a few minutes later my roommate emerges and lays down next to him. 

I felt so incredibly dirty and slutty and I never told him...
