Professor to Sissy Slut

He got off my chest and ordered me to take off my panties. He held his hand out and I handed them to him. He then shoved them in my mouth. "This is to keep you quiet while I take that pussy of yours." I could taste my own precum on the panties. He flipped me over onto my stomach and pushed my legs apart. I thought he would arrange me on my hands and knees, but he didn't. I could feel him fingering me again and I was moaning into the pillow. He had some lube that he had brought with him and he applied some to my ass. It was kind of cold. I couldn't believe I was about to get fucked. I also couldn't believe that I really wanted him to fuck me. I could feel his cock pressing against my hole.

"Relax," he said, "it will be easier that way." I did manage to relax some and I groaned as the head of his cock slid into my ass. I was a little surprised and glad that he was actually kind of tender about taking my virginity. It hurt a lot at first and I groaned again and he told me to relax and take it. It took about ten or fifteen minutes of slowly sliding a little more in a time before I could feel his balls touch my ass. I felt so full. Then he slid his cock almost all the way out, then slowly all the way in. His hands were pressed into the mattress on either side of me. He did about twenty more long, slow strokes, then grabbed my hips and pulled me back toward him so that I was on my knees. I leaned up on my hands, but he put his hand on the back of my head and pushed it down. He began to pick up the pace. Now I was truly his sissy bitch. If my students could see me now! If my wife could see me now! Now he was truly giving me a fucking. He pulled back on my hips as his cock slammed forward into my ass. After a while, I realized that I was pushing back into him. It now felt so good to be fucked by him. He reached around and pulled the panties from my mouth.

"Who's my bitch," he yelled.

"I am!" I moaned back.

"You are, what?" he said.
