Half drunk over at Marks house, it was so nice of his father to leave us booze to enjoy. We were both buzzing, kissing, and in the nude on his comfortable bed. Our penises touched each other as we kissed, and looking into his sultry green eyes, I felt compelled to let him do what he wanted to. We had already enjoyed kissing, hugging, and sucking each other off with a fury of passion. The moment of truth had arrived, as Mark came clean to me. When his dad was posted in Nicaragua, he used to fuck a guy regularly, and wanted to be inside of me. At first I was stunned, as he hadn't told me about that, as I missed my best friend when he was out of the country. Yet at the same time I was relieved to hear this, as I had never had an encounter with any anal action in it. There was a lot of trepidation, sweat, worry, and conflicting emotions about what this would mean. It was one thing for our tongues to dance rhythmically, or to take each other's cocks in the lips of our mouths. This was all new territory, and while there was some excitement, mostly I felt dread. To think I was going to have a man in my rear end, was something that scared me yet at the same time admittedly caused some intrigue. I really loved Mark, kissing him and being his lover, so I wanted to please him and make him so very happy.
I got turned on, as how he told me, that when he had sex with his Central American friend, they'd both cum. It seemed impossible, but looking in his eyes of green sexiness, I knew he was telling the truth. As the booze piled on, and we continued sucking each other off, I felt a wet finger start to slide inside me. At first I buckled. "What the fuck?" Mark looked at me and said, "just relax as youlll like this." After more kissing I felt his finger and a different type of pressure than I'd experienced. It didn't really hurt, but it wasn't something that tickled my fancy. I let him continue as I laid down prone on my back, and he massages my balls gently with his other hand. Unnerving and in a precarious position, he came up next to me, and looking into his gaze I felt comforted. He promised to stop if I asked, and even though the conflict ran through my psyche, I didn't resist as he pulled my legs up.
His cock looked harder than ever, and was shiny from lube he placed upon himself. I was surprisingly turned on, as the head of his cock nudged my rear end, with him very gently sliding in. Mark told me to "push out," and I could feel his penis enter me ever so slowly. At first it just felt like a new sensation of pressure, but it did hurt, and I turned my head to look away. Further he slid in and although I was nearly in tears, I managed to hang on for what it was worth, as he penetrated my virgin ass. He was moaning and although I hurt, part of me was turned on to see his cock disappear in me. His hands felt so good on my ankles, and his green eyes looked like fires of crackling passion, as I watched his sexy hips moving back and forth.
A few minutes later, although it felt like hours, I felt his body go rigid. He looked up at the ceiling and I could feel his warm goo inside me. It must have been a gallon of his jism, and I felt kind of humiliated. Embarrassed. A guy had just sodomized me and I started to freak out. Thankfully Mark reassured me gently, as I found out quickly the power of a very kind hug. My rear end hurt and although I didn't cum, I was glad Mark did as he just became more sexy every time we were together.
