We kept talking not noticing that night time had fallen. Around 9:00 pm we stopped and just looked at each other. I said, "Joan what a great time I've...had talking to you." Joan said, "Me too. Let's do it again." We both needed to go to our rooms. When she left she pecked me on the cheek. My heart leaped. We had coffee nearly every day for the next few weeks. I was falling in love. I hoped she was too. We finally went on a real date. We had dinner and went dancing. When I held her in my arms I. She obviously was not happy.“Look at this fucking thing! He only gave me a C on it.” She had it in her hand and she shook it at me. “What did you get?”“Ah, a B.”“What kind of jerk-ass stunt are you trying to pull? You think you didn’t have to put any effort into my paper?”“Nora, simmer down. Let me see what he wrote on it.” After looking at hers, and then my own, I said, “I think the one I wrote for you is actually better than the one I did for myself. I don’t know what his issue is; sometimes. “Why are you smelling my panties?”Embarrassed, unable to answer, I stood with her panties in one hand and my throbbing cock in the other. Sis stood naked in the doorway. Her eyes never left mine. “Go ahead,” she nudged, “Finish what you started.”I was too fucking hard to argue. My hand started stroking up and down my young cock again. I watched her eyes fall to watch my labor. She took a step into the bathroom and leaned back on the wall. I couldn’t take my eyes off her body as I stroked. It was glorious to betouching her, tasting her, serving her, and focusing completely on herpleasure with no thought about my own.Gradually I built her up toward a climax. I concentrated more on herclitoris. She was muttering and speaking single syllables that didn'tform words. She pressed her thighs against the sides of my head and Itook it as a sign of approval. I was so happy to be able to repay herfor what she was doing for me. At the same time, it was becoming lessand less easy to deny.
