After I picked up parts and tossed them into the back of my car, but I sat there in the driver's seat for roughly an hour, dreading going back to that hell. I gritted my teeth and turned my car on and drove back.

As I was walking into the building, I couldn't feel awkward with all the stares I was getting and I wasn't sure if it was the large box that I was carrying or what, but I wanted to get to my room real quick.

I got closer to the dorm when I heard moaning. I turned my foot to head back to my car, but decided to bite the bullet and unlock the door. The place was darker, with me expecting one of them or both on the couch, but no one was there or in the kitchen. I placed the box down on the table  and followed the moans. If I can get some dirt on them, then my life will be better. Imagine my surprise when I saw them on my bed and Sarah eating Jesse out, they didn’t even close the door .

“That's it, you mindless slut, eat your Mistress out.” Jesse screamed as she dug her fingers into Sarah hair, “Remind me to thank Virgin when he gets home.”

Sarah stopped eating enough to say, “Yes Mistress, I will let you know to thank him when he gets home.”

I couldn’t take it anymore, “What the hell is going on?!” 

Jesse shrieked as she tried to close her legs, but couldn’t with Sarah still between her legs. “Nothing, just the fact that we can have sex wherever we want, Virgin.” She pushed Sarah’s head out of the way and straightened her clothes. “This is punishment for not making any coffee or breakfast for us this morning.”

Sarah sat back on her toes, “Mistress, remember to thank him for the collar.”

Jesse’s cheeks went bright red. “Shut up!” She yelled at her as she clasped her across the mouth, “I said no such thing.”

I just shook my head, walked over to them, and clicked the release clasp on the back. It was like a switch was flipped in her as it clattered in her lap. She shook her head, “What the hell? Why does my brain feel like a smoothie?”

“You wore a prototype without it having anything to block interference or feedback. You tell me why you feel like that.” 

Sarah shrank for once under my gaze, “S-sorry, I was just messing around and put it on. We thought you were going to give this trashy collar to someone.”

I snatched it from her lap and tossed it onto the desk. I would care about the damage later, but I had to deal with these two. “You had no right to go through my stuff, especially with a prototype that needs to be tested properly!” Jesse opened her mouth, but I beat her to it, “And no, that’s not the use of it. It’s supposed to help the people that didn’t have good use for hands to have a computer. It sends a Radio Frequencies to the computer, like a wireless keyboard and mouse. You wore it without me making it one way, so you had no signal going back to you, so your brain computed commands as a signal, now get out before I report the both of you! And the whole building heard you.” 

I didn’t know if that last part was true, but it felt good to see their faces change between humiliation and embarrassment as they scrambled out of my room. I sighed and knew that I had to apologize to them, but for them to do that was way too far for them. If they damaged it or lost it, then I would be out of luck for tomorrow. I winced when it hit me how I just treated the collar, I guess I couldn’t get angry with them about that.

I walked over to the collar and looked it over, then I sighed with relief at its state, before walking back out to get the box of items. Jesse and Sarah were nowhere to be seen, but I could hear the shower running, and I guess the other was in her room. I picked up my box and walked back to my room. I closed the door while knowing that it wasn’t going to do anything to keep them out, but it was worth a shot, and got working on the gem for the front. I added a light connected to the transmitter into the gem and slotted it in. The gem flashed blue before it turned red when I tested it out. I nodded with satisfaction that it was working and removed the other signal from it. I wasn’t going to test it on myself, so I had to hope that it was good, then I got a better idea for the metal insides. I could make it links instead of of a flexible and weak type of metal. That would make it more fluid and work a lot better. With a heavy heart, I took it apart and started working on putting it back together 

After hours of working on it, I slid the last of the leather in place, then I slid it around the mannequin’s head to see out it looked, and I couldn’t help but imagine it around their necks. I shook my head, then heard a knock on the door as it was pushed open. I turned around just to have my jaw drop open. Sarah was standing there in the doorway in a towel, her massive breasts were pushing out of the top. She bowed her head and said, “This is the only time I’m going to say it, I’m sorry for wearing it. And now you’ve seen the closest thing to a naked female that you’ll ever get, Virgin.” She turned around and I saw the bottom of her ass as it pushed the towel out.

I turned around quickly as I felt my cock painfully strain against my pants. That does it, I’m going to make them a set of special collars. But I was exhausted, so I skipped dinner and just went to bed.

I woke up to my alarm and hurried to get ready. I had the testing this morning, and needed to get there in 15 mins. I pulled out my map to see that it was across the campus. I scrambled around and ran out the door, but not before I remembered to start the coffee for them.

The campus seemed to be barely waking up; a few people were jogging around, and the grass shone with morning dew. I wrapped my light jacket around my body to keep the early summer chills at bay.

I burst into the room with a minute to spare, and the two teachers and the subject were sitting at the table as they seemed to be filling out papers for the subject, since she had casts on her arms. She turned to the door with a look of hope in her eyes that was covered with helplessness and sadness at her state. They looked to see what got the subject’s attention. The male stood up and walked over to me. “I assume you are Mr. Stone, the one that doing the testing?”

He nodded when I confirmed who I was, “Good, this is Kathlyn, she’ll be the one who will be testing it. Mrs. Johnson and I are here to see if it works. May I see the collar?” I nodded as I handed him the collar. He muttered as he looked it over, “This is nicely made, I see you did segments inside to allow it to be more flexible and leather for comfort.

I noticed Mrs. Johnson pulling out a small laptop as he handed me the collar while saying, “We already filled the papers stating that we know and consent to what is supposed to happen, but we’ll take action if it goes wrong. You may begin.” He sat down next to Mrs. Johnson and interlocked his fingers together as he waited. I gulped and walked up to Kathlyn. Her eyes looked up at me, and I took in more details. Her casts went to the nearly the tip of her fingers, and her short hair was matted, so she probably has someone to help her do everything she’s unable to do. She gave a weak smile before looking forward and giving me access to her neck. The collar was a bit snug, but didn’t seem to be cutting off her oxygen. Then I turned it on, plugged the dongle, and took a step back. The gem flashed red a bit before it turned to a solid blue.

Mrs. Johnson spoke once I was done, “Sweetheart, you can go ahead. Open the Word program and type out your consent form, then hit save. You can look over mine if you need help.” She slid the paper over. I held my breath as Kathlyn nodded and focused intensely on the computer. I felt anxiety and dread when I saw nothing happening and could see the hope turning to desperation in her eyes. I was about to walk over to remove the collar, when the document program opened up, making her eyes widen. It started to fill word for word of the consent form, until it was half way done, then she broke and started crying. Mrs. Johnson went around the table and cradled and comfort the student as she cried with joy. She turned to me and mouthed, “Good job.” I left my prototype with them, since i don’t think I’m going to ever get it back, but I had more important things to do now, get revenge on my two roommates.
