I was at my boyfriends dorm last week. He has three other roommates. We were relaxing on a Friday night, drinking and getting high. We had sex and my boyfriend passed out on his bed. I went out to get a drink of water just wearing my thong since I thought all his roommates were out. His one black roommate must have thought the same thing because he was naked in the kitchen getting a drink of water. I never found him all that attractive. He was a really skinny guy with dreadlocks but he had like a third leg hanging between his legs and for some reason I got really horny looking at him . Maybe it was because I was high but I got down on my knees and just started sucking him. He was kind of nervous about my boyfriend coming out but he didn't stop me. We went into his room across the hall and I had him lay down on his bed. I then rode him for who knows how long but god I came so much on his big dick. If my boyfriend had woken up I still wouldn't have cared because I was in fucking ecstasy. He held onto my ass cheeks until he could not take anymore and came inside me. I think I am going to become addicted to his big dick and will probably go back when my boyfriend is gone to get some more
