I arrived at Professor Cooper's office promptly at 4 as she had requested. Her office door was open when I got there so I knocked on it lightly as I poked my head in.
"Professor?" I asked.
"Yes, come in, Steve." She said from behind her desk. "Shut the door behind you and please a take a seat."
I shut the door and nervously sat down on the chair in front of her desk. She looked at me for a moment without saying anything, and then said,
"So in class today you told me that you were desperate to pass my class and that you would like to do some extra credit. Is that still the case?"
"It is," I told her. "I really need to pass this class, otherwise I might not be able to graduate on time."
"Well right now you really have no hope of passing my class. If I were to give to give you a passing grade you extra credit would have to be quite...strenuous."
"That's fine," I assured her, "I don't mind doing the extra work. I just really want to pass." Something about the way that she said the word "Strenuous" sounded strange to me but I didn't pay it any mind.
"Well, we'll see if you can manage what I have in mind." She leaned back in her chair and unbuttoned the blazer that she was wearing. I tried my best to keep my eyes off of her perfect tits which were now straining to pop out of her tight fitting white shirt.
"There is only one section left in my class, Steven, do you know what that chapter is on?"
"I'm sorry, no I don't." I told her.
"Well I guess that's to be expected, anyone who has grades as poor as yours couldn't be expected to look at the syllabus. The last section in my class is on female domination in sexual relationships."
"Oh, ok." I said.
"You seem surprised, but after all this is a class in human sexuality and female domination is a part of that. It also happens to be my favorite subject that we cover in this course which is why I always save it for last."
I shifted uncomfortably in my seat for a minute as I waited for her to go on. She focused her eyes intently on mine and I found it uncomfortable to meet her gaze despite her obvious beauty.
"Are you familiar with that subject matter at all, Steven?"
"No, I'm not." I told her.
"Well you are going to need to learn it, one way or another. So you have a choice - you can finish the class like a normal student, in which case you will fail the course and not be able to graduate on time, or you can perform extra credit for me after hours. Do you know what you would like to do?"
"Yes, Professor, I would like to do the extra credit. I really want to pass this class and I'm willing to do what you need me to do."
"Well that's good Steven, I think that you are making the right choice."
She opened up one of her dress drawers and took out black velvet bag and she placed on the desk in between us. The bag made a slight thumping sound as she put it down. I wondered what was inside it, and why she had taken it out now, but she made no effort to satisfy my curiosity.
"Your extra credit will begin tomorrow morning, Steven. Be at my house at 9 o'clock in the morning. Tomorrow is Saturday so plan on spending the full day with me; we have a lot of work to do."
"Sounds great," I told her, "I'm looking forward to it. And thanks again for giving me this opportunity."
I started to get up but before I could she stopped me.
"Don't thank me yet, Steve. Lets see how you do with your extra credit assignments first. I also want you to take what is in this bag."
She handed me the black bag on her desk and as I took it from her hand I could feel something hard inside that had an unusual shape.
"Inside there is something for you. Make sure that you have followed the instructions in there before you get to my house tomorrow. Open that bag when you get back to your dorm room tonight."
"I will, and thanks again Professor." I said as I turned to leave her office.
"One last thing, Steven. You remember what I told you this last section was on?"
"Um, female domination in sexual relationships." I said quietly so nobody in the hall would hear me.
"That's right," She told me. "Don't forget it. You may go now."
I walked back to my dorm room as quickly as I could without arousing suspicion and when I was alone in my room I opened the bag that Professor Cooper had given me. At first I didn't know what I was looking at. There was a clear plastic tube and a plastic ring. Right next to these two items was a small stainless steel lock. The lock was open but there was no key in the bag with it. There was also a small piece of paper with a few words written on it:
"Put this on and be at my house tomorrow or fail."
