I could eat my food and be rude, or I could wait for Gwen's to arrive, and risk my own food getting cold."Sorry if this seems rude, but I'm hungry," I... said as I shoveled barbecued pork into my mouth. I did try to eat slowly. Gwen got her food long before I finished with mine. I ate the over spiced barbecue with Gwen staring at me in disbelief."What?" I asked."How do you eat that stuff?" she asked."Tums," I answered."By the handful I'm sure," she suggested. Prissy Gwen was hardly into her food. My heart began to quicken and breath ran short, I knew what she had come for. Assertively without waiting for me to speak, she kissed me sharp and sudden, rough and hotter than the sun on my face. I had never been with a woman before. This was different, softer almost. Still lying there on the bench, she leaves my lips to travel along my body. She kneels between my legs and looks at me. She reaches up and takes a clothed breast in one hand, and fondles and presses til I sigh. My eyes. I heard a creaking noise and stopped. I realized that I had forgotten to knock, and when my sister found out she would be pissed. She was always telling me to knock on the attic door, but I always forgot to. I ignored the noise and continued towards her bedroom door, which was open slightly. I was about a foot away from the door when I heard another creak, and what sounded like my sisters voice. I froze and tilted my head to look in her room. My sister was lying on her back, and her boyfriend. This was the best oral I had ever had. I've always fantasied about fucking Jane's face just like this, and now it was actually happening. She sensed what would be coming and broke off for a second telling me not to cum in her mouth. I was gutted. That part turns me on the most. I pleaded a little asking if I could cum in her mouth, but she was adamant against it. I was in a powerful position holding her head and thrusting into her mouth and could have easily continued until I shot my load down.
