This happened couple of years ago while I was living in a new city while working at my first job ever after graduation. I was 22 and I was living in a house which had 4 bedrooms each being rented out to different people. So, I had 3 room mates living in the adjacent rooms. They were all male. Two of them were of about my age while one guy was few years elder. I was a good looking fit girl by any standards.
I was a horny girl at that time with a higher than normal sex drive. I had one night stand kinda things with all three of them over next six months. This brought us closer together and we used to hang out together all the time, although none of them were aware that I had sex with other two guys too.
One night we were drunk and a guy foolishly uttered how he was attracted to me and how great the sex was. Then there was a silence and other two also said that they had fucked me too. Now, everyone was staring at me in a particular way. The drunk guy called me a slut and I felt really humiliated.
