She wasn't coming with me, so I was confused. On the second night of my trip I got a series of texts from her instructing me to "clean out my ass", sh...wer, and brush my teeth. I did as I was told, expecting her to show up as a surprise. After I showered, she called me. She asked if I was ready for my surprise. I said yes, eagerly expecting some kinky sex with her. Suddenly there was a heavy knock at the door. I looked out the peephole and saw a young guy waiting. I asked her what was going on. This wonderful man, with his hard, dripping cock, made my heart leap when he whispered "Yes." He was going to fuck me. I pulled my pants all the way off to I could spread my legs properly. I wet my fingers and lubed up around my asshole as best I could while turning around. He had pulled himself more through the space under the divider. I began to sit down on his cock.As I knew it would be, it was pure pleasure for me. It was heaven to feel his head stretching and forcing my asshole. Once his. Part of her was disappointed, but on the other hand, she reminded herself, that that was what she had wanted. Finally the day of the art museum trip came and she and her classmates prepared for the trip. They would be walking, as the museum wasn’t far from the campus. As the students, bundled up in scarves and hats, huddled together on the sidewalk, Mr. Daughton strode toward them to round them up for the trek. The students mostly walked in groups of three or four, groups of friends walking. I could feel his cock begin to shrivel up inside me. Then he flopped onto his back and began to half laugh, half cry. I had never seen a soft cock before and I knew that my big mouth had caused it. I wanted to kill myself, I felt so stupid. And I knew that it was up to me to correct the situation. But I also knew enough to shut up.I slid down and took his limp dick into my mouth. I had never before had any kind of cock in my mouth, hard or soft. But I knew from the porn I had seen what to do.
