“Yes please”. I pull my cock out of Kelly’s vagina and bring it up to her ass. The professor gets up off the chair and stands close to us. I ...lide my cock into Kelly’s ass. “Nice” says the professor before moving back to the chair. I mostly high doggy fuck Kelly’s ass. After 10 minutes I feel the orgasm start. I pull out and blow my load over Kelly’s back. As we clean up and get dressed Kelly tells the professor that she had fun having him watch us. The next time Kelly and I meet she. " She started crying again."Daddy, I am so sorry! I'm sorry for what I got myself into, for how disappointed you must be in me. I've never wanted anything more than to please you. Instead, you find out I am the slut that Amy said I was. God, how you must hate me! I'm such a hypocrite; criticizing something beautiful that you and Cindi had, when all the while I was common whore. Worst of all, I endangered you and Julie. I don't deserve either of you.

I climb off quickly and get on the floor in front of him on my knees and elbows. My open arse pointing at him. I tell him to fuck. He then kissed me. I could taste me on his lips, it made me even more aroused. I tried to turn my head away in disgust of myself. He forced my face back and slapped me again across the face. “I told you to cooperate didn’t I?” He asked. I didn’t answer. He slapped my face on the other side this time. “Didn’t I?” He said again a little louder this time, even choking me a little more. I nodded. “Say it.” He said. “Yes.” I whimpered. “Yes, what?” He asked me. “Yes I will cooperate.” I said softly..
