It was few months after my first and I was working in a small clothing store in a fairly small town that has a large University, the girls I worked wi...th were all younger than me by at least 10 years and they loved to hang with the blacks and I liked to heard their stories about black boyfriends, it seemed like they all dated black men. One girl was from a rural part of the state and her name was Susan and she was just crazy about black men. She once brought two to my apartment and then took one. I was happiest when the third person had a cock and Mark enjoyed the additional pussy. One night we discussed our preferences and Mark shocked me by saying that our choices were more a result of societal conditioning then anything else. Mark is a psychologist and loves to believe he can understand the human mind. When I told him that hetero sex was natural, or that it was nature, not as he believed nurture, that put men with women, well that's when he challenged me.His idea and I'll admit it. "I thought you would like it, I picked that flavor just for you". "It's my version of a gold star, only my students willing to take on special projects gets it". His special project was driving me crazy. I allowed my lips to consume every inch of him. My cheeks collapsed around his dick, I couldn't let go. There was so much of him. My head moved quickly allowing my lips to place kisses within the hairs around his dick every time they met. I looked up at Richard just in time to see his eyes roll. Her head was we with precum and I quickly licked it off before taking her cock in my mouth. It was rock hard and tasted great, it was like no other cock I’d ever had, it was almost sweet. The smell of her feminine lotion made it taste even better. As I sucked her cock I slide my hand between her legs and grabbed her sexy ass. I slowly worked my way in between to her hole and gently stared playing with it. At first I ran my finger around the outside, giving it a nice massage.Finally, I gently.
