text: “Good job, Katy! One gold star for you. You can use it to get something in the Learning and Motivation store.” Dr. Biff Skinner, my psychology professor. He’s pretty funny and makes the class experience enjoyable, even when the material is boring and dry. He’s one of my favorite professors, but he’s the only one that I want to fuck. And I have a plan. I went to his office later that day. His door was open and he was on his computer. I stood and watched him for a few seconds before I knocked. He looked up, smiled, and welcomed me in. I walked in and shut the door behind me. He looked a little surprised that the door was shut, but didn’t say anything about it. “What can I do for you, Katy?” Dr. Skinner said. “I’d like to redeem my gold star, Dr. Skinner.” I said with a grin. “Let me guess, you want an ‘A’ on your next exam?” he replied jokingly. With as much courage as I could muster, I replied, “No. What I want is for you to bend me over your desk and fuck me from behind.” He seemed a bit startled, but quickly recovered and said with a devious smile on his face, “Well now, you’ll need more than one gold star in order to get that.” “And just what would I have to do to earn enough gold stars?” He stood up from behind his desk, looked me in the eyes, and unzipped his pants. “This would be a start.” I walked over to him, got down on my knees, and took his cock out of his pants. I started licking up, down, and all around his cock and balls, allowing the tip to go in my mouth every few licks. When his cock was covered in my saliva, I slid him all the way into my mouth, letting my tongue play with the underside of his cock as he was thrusting in and out. My hands went to his balls, massaging them and rubbing his taint while he was thrusting and moaning. His hands were bunched in my hair, guiding his cock into my mouth. He was moaning that he was cumming, so I sucked harder. He shot his load into my mouth and it slid down my throat. I swallowed it all, stood up, wiped my mouth, and asked him with a wink, “Did that earn me enough gold stars?” “Oh God, did it ever!” He replied breathlessly. He pushed me over his desk, pulling my shirt off in the process. I wasn’t wearing a bra, so I was naked from the waist up. He pulled my panties down in one fell swoop, pushed my skirt up, and thrust into me hard. I moaned so loud I was sure someone would hear me. He thrust into me harder, holding my waist to keep me steady. It only took five more thrusts and I was gone. I came so hard that I shivered. He came again seconds later. I lay breathing hard on his desk for a few seconds, trying to catch my breath. When I got up, he looked at me and whispered with a smile on his face, “Good job. One gold star.” I put my shirt back on, pulled my skirt down, leaving my panties on the floor of his office as a little remembrance for him. I winked at him, opened his office door, and walked out with his cum running down my legs. As I passed the student aid, she openly stared at me, so I knew that she had heard at least part of what happened in there. I put my finger up to my mouth to tell her to keep quiet and walked out of the building. I can’t wait to earn some more gold stars.
