Playing With A Poz Friend

While I was in college, I dated this older guy and he introduced me to his friend who is positive. After we broke up, the poz friend and I stayed in touch and recently, he expressed an interest in having sex. I've never discriminated against anyone because they are poz, and I though he was really hot so we met up. After talking in his living room for a few minutes, he takes my hand and guides me into his bedroom. We start getting hot and heavy on his bed and he turns me onto my stomach and starts rimming me. I have such an anal fixation, so I was in heaven. He then got on top of me and started guiding his cock into me. I sort of tensed up and he sensed my discomfort and stopped. He apologized and stood up by the side of the bed. At that moment, his cock looked so good and my mind lost control of my body and I crawled to the edge of the bed and begged him to fuck me. In one quick motion, his entire member was inside of me and I loved it. Although it didn't take him long to cum, I was satisfied.
