I (19f) let my roommate fuck me while his girlfriend was in the next room

so this happened last weekend and i still cant stop thinking about it. me and my roommate have been living together for a few months. he has a girlfriend who stays over sometimes. theres always been this quiet tension between us but nothing ever happened until now.

his girlfriend fell asleep early on the couch after a movie. we were still up in the kitchen cleaning. he came up behind me while i was washing dishes and put his hands on my hips. i froze for a second then leaned back into him. he was already hard.

he turned me around and kissed me hard. hands under my shirt, squeezing my tits, then down my shorts. i was soaked. we moved to his room quietly. he locked the door. pulled my clothes off fast and pushed me onto the bed. licked me for a minute then climbed on and pushed in raw. no condom.

he fucked me deep and steady at first then harder. one hand over my mouth whenever i got too loud. the bed was creaking and i kept thinking she could wake up any second. he flipped me onto my stomach and went even deeper. kept whispering how tight i felt and how long he wanted this.

i came first with my face in the pillow. he lasted a bit longer then buried himself and filled me up. i felt every pulse. he stayed inside me for a while after then pulled out slow and watched it leak out of me.

i cleaned up the best i could and went back to the living room. his girlfriend was still asleep. he came out later and acted completely normal. i sat there with his cum still inside me the rest of the night.

we havent talked about it since. but the way he looked at me the next morning told me its going to happen again.
