My Boyfriend And The Roommates

When I was in the University I got my first long term boyfriend. I had only few encounters before that and only once had real sex. I was living in a dorm and he was renting apartment with two other guys. For obvious reasons we were often at his place and after half a year or so I was used to see the other guys in underwear and they saw me occasionally. One weekend we were alone, watching a movie with my boyfriend and didn't expect the roommates coming home. I was only in panties and t-shirt he in boxers and shorts. We were chilling on the sofa when one of the roommates came back home, he was not surprised to see us there and casually sat next to me. There were some erotic scenes and he commented that that I look sexier than the girl on the screen. My boyfriend laughed and said that my boobs are prettier and should show them. After few minutes into the sex scenes and talks I ended up topless and we were casually talking about sex and how likes what etc. My boyfriend said that he had fantasy watching real life sex, the roommate joked he will do me right away if we let him. Few seconds later my boyfriend was like ohh really and excitedly encouraged me to agree. I wasn't entirely convinced I wanted it too and tried to fend off the offer, told them to take some drinks and I'll think about it. They went to the fridge and brought beer, on the way back to the sofa I saw the bulges, they were getting exited. I was curious to be with other men but not actively pursuing it. We had the beers, talked, then I just dropped it to the roommate, ok fuck me. He stood there just not believing it or was surprised. I reached to the bulge in his trousers and told him to undress. He stood up and by the time he took his clothes off he was already fully erected. I took off my panties and he went down between my legs liking my clit and slid his tongue inside me and made me wet. Kneeling pulled me down to edge of the sofa and spread my legs, rubbed the head on my drooling lips and pushed it inside. Slowly fucked me like that for some time, my boyfriend sitting next to me was still dressed but took his dick out, I've never seen him so hard. The roommate turned me doggy and now was going faster, my boyfriend stood in front of me now undressed and pushed his dick in my mouth. I don't know how long like this they swapped, my boyfriend was fucking me like animal while I was licking my juices off the roommates dick. I heard the front door and realized this was the second roommate, me spit roasted and he looks at us, few moments later he rushed to his room. No one said a word nor stopped. I felt my boyfriend changed pace, slowed and went harder and deeper, he was cumming. The roommate I was sucking told me he is close too. My boyfriend exited me and went somewhere. I was focused on finishing the roommate when I felt hand on my ass and dick entering me, I though my boyfriend came back for second round. Soon the roommate shot his load in my mouth, I had to swallow it, my first time. I was close, turned my head to the side and back just to see my boyfriend sitting in an armchair rubbing his dick and the other roommate ramming me from behind, then I just felt the orgasm. Minute or two later the roommate came inside me. Later my boyfriend told me he went to the second roommates room to ask him to fuck me too. The next weekend we did the same. We continued in this arrangement for the rest of our UNI years, I moved in with them.
