Domo arigato Mr. Roboto

We started to kiss. I started at her lips but quickly moved to other areas. Kissing her neck, nibbling in her ears, and kissing that spot where the V of her collar bone is. Running my hands through her hair and down her back, I grabbed her firm round behind, picked her up, and tossed her on the bed. She landed, giggling. 
 
I dropped my robe and grabbed her feet, yanking her towards the edge of the bed. Tessa yelped and giggled again as I started kissing the tops of her feet down her calves, licked the back of her knee, causing another burst of laughter, and continued down the inside of her thighs. The giggles started to turn to moans as I got closer to my target. But I wanted this to last a little bit longer than just this brief foreplay, so I skipped her sex and started back up her torso.
 
Giving her little rakes and using my fingers up and down her sides, I continued to kiss her stomach up to her lovely breasts. Latching onto a nipple, I lightly sucked while swirling my tongue around her nub, licking and flicking it. Finally giving her a little nibble before moving to the other breast. Giving it a similar treatment while squeezing and caressing her other breast. All while this was going on, Tessa was getting more flushed, and she was moaning more than giggling now. 
 
All of a sudden, she stopped me. I looked up at her, worried I had hurt her or done something wrong. 
 
"Matt, before you make me yours, there was something I wanted to see if you could do. I don't know how all this works, but I thought it might be the last time to speak up..." she finished.
 
"Of course, Tessa, if I can do it, I will." I said 
 
"I have always been into technology, and my favorite movies have always been science fiction. Since I was little, I always had a fantasy, which has become more of a fetish, to be turned into a robot. To have a machine mind, to know everything and calculate anything, but to have no other thoughts about what people think of me or if what I am doing is right." She said nervously, quickly following it up with, "I know I can't be like that all the time. But could you do that? Could you make it so I could be like an unthinking robot sometimes? It would be so fucking hot for me." She was blushing furiously.
 
"I think I can do something like that," I explained. "It will be the first time, but I had to program Madison a bit because she thought I was the bad guy, so theoretically it should work." I said. 
 
"Well, then theoretically, why don't you keep fucking me into a sexbot, Master?" She purred, smiling. 
 
"Command accepted," I said in a robot voice, then laughed, grabbing her and flipping her over, caressing and kissing her generous buttocks. I could see her honey pot, obviously ready for sex. I decided to start eating her out from behind. 
 
"Oh my God, yes, Master, don't stop." She moaned, and I wondered if this was her first time getting eaten out. 
 
After working on her from behind for a bit, she was breathing heavily and practically panting. It was time to move on to the final position. Flipping her back over, I lifted her legs up like and spread eagle, burying my face in her sex. 
 
I penetrated her vagina with my tongue, curling up to stimulate her g-spot while rubbing her clit and hood with my nose. Starting to uncontrollably thrust her hips into my face as she got close to orgasm, I had to move up. I started licking and teasing her clit with my tongue, raking my fingers down the outsides of her legs. Her moans got louder and longer as I headed towards the goal. As with all the others, there was a point where my tongue spasmed, surrounding her love button, and I received an electrical shock, blanking Tessa's mind and leaving me with a numb tongue. 
 
I slowly rose up, seeing her staring blankly at the ceiling, her head slightly lulling to the right. 
 
"Tessa, can you hear me?" I asked
 
"Yes, Master, your **** hears and obeys," she replied without emotion. 
 
"Good ****, I want you to listen to me. I am going to give you commands; these will become a part of you. You will obey these commands and any others I give you. When I am done, you will repeat them back to me and obey. Do you understand?" I finished. 
 
"Yes, Master, this **** will listen and repeat your commands back. I will obey." She droned. 
 
I listed the most important things for me to do in Tessa's programming. You would think that I would just have a boilerplate "create a ****" document or something by this point, but because I wanted lifelong partners and not mindless slaves (not that it was a bad thing, but not for the girls I knew and had a relationship with), I decided to give individual commands based on what I knew about them and me, not a generic list.
 
"Tessa, my commands are:
 

1. You will love and obey me, your Master.
    
2. You will honor and obey my wife and head of my harem, Jen Cole.
    
3. Your first priorities are to the harem and harem members after myself and Jen. 
    
4. You will not be jealous or have animosity towards any of my slaves; they are like family to you, and you should embrace them. 
    
5. You will have no problems with **** or having sex with multiple partners or different genders. 
    
6. You will continue to have your own mind and opinions unless I command you otherwise. 
    
7. When it comes to my health or the health of anyone in the harem, you will freely tell me your opinion on whatever matter is being discussed. 
    
8. You will continue to develop your skills in AI and cyber security for yourself and the harems well-being. 
    
9. If, for any reason, what I command you to do hurts you or someone in the harem, tell me immediately.
    
10. Lastly, when you hear me say the phrase "Activate Tessa Bot," you will change into a super smart robot who has no emotions and can do complex calculations and recall facts that exceed Tessa's abilities. Tessa Bot will not have to worry about her actions or interactions with humans. During this time, she will also obey any sexual or other commands that I give her, as if she were an obedient robot. When I say "Tessa Bot sleep," you will return to being **** Tessa.
     
    Repeat these commands back to me, and once you do, you will obey them completely. Begin" I finished. 
     
    Tessa blankly repeated everything back to me with complete precision and then fell silent, still a mindless meat puppet, until I made her orgasm again. I had a few things I wanted to try, so I got back down between her legs and started to finish what I had started. Soon, even blank, her hips were thrusting into my face. Finally, she came with a fairly loud moan, shaking and throwing her head back. Slowly, her head came forward, intelligence coming back to her eyes. 
     
    "Oh my God, Master, that was amazing. I feel like I just got zapped by a lightning bolt!" She panted. 
     
    "Well, you kind of did," I said. "It's part of how my powers work." 
     
    "Can we do it again?" She asked 
     
    "No, but we can do plenty of other things that feel great." I said. "Stand up. I want to try something." 
     
    "Ok, what are you going to d-"
     
    "Tessa Bot activate," I interrupted. 
     
    "Yes, Master Tessa Bot hears and obeys." She said this after straightening up and standing at attention. 
     
    "Tessa Bot, what is the square root of 3952?"
     
    A second later, Tessa Bot responded, " 62.864934582......" She continued. 
     
    "Tessa Bot, stop," I said. She stopped."Tessa Bot, who was the vice president in 1945?" I asked 
     
    "Harry S. Trueman was vice president in 1945" she robotically said.
     
    "Very good, Tessa Bot. Get on your knees and give me a blowjob," I said. 
     
    "Tessa Bot hears and obeys," she said, taking a step towards me and dropping to her knees. She immediately brought her mouth to my hard dick and engulfed it to the base. Robots must not have a gag reflex, I thought. Her technique was amazing, but this was just the warmup. 
     
    I told Tessa to stop and to bend over the chase lounge with her ass in the air. "Yes, Master Tessa Bot hears and obeys." She walked to the piece of furniture and pent over the armrest, presenting her puckered hole for me. With my dick already covered in her saliva, I grabbed a little Vasaline off the side table and applied a little around and in her ass. I ordered her to relax her ass, and she immediately did. So I slowly and carefully pushed my dick into her bowels. Even when relaxed, she was incredibly tight, causing me to feel every texture inside her with my dick. It was a little odd; I fucked Tessa's ass until I came, filling her ass with my seed, but there was no reaction, just like a robot, or sexbot in this case. 
     
    It was about this time that Jen and Madison came into the room. Both dressed only in panties and nothing else, just as I like it. Apparently Tessa's last orgasm was enough to wake them up, so they came to investigate.
     
    "What's going on here?" Jen asked. "Why is Tessa bent over the chase with your cum leaking out of her ass?" She said she was giving me some attitude, like she was an upset girlfriend. The only thing that ruined it was her face, which was smiling. 
     
    "Tessa told me to make her my ****, so I did." I said. "Tessa stopped me before we started to tell me that she has had a fetish for turning into a mindless robot, so I made it part of her base commands. Then I fucked her in the ass because I wanted to see how it worked." I finished. 
     
    "I see," said Madison. "This was all agreed up front." She asked, her eyebrow raised. 
     
    "Of course it was!" I said, "You know I wouldn't do anything like that without asking first." I said
     
    "But then you fucked her in the ass?" Jen asked, "Did she agree to that?" She teased.
     
    "Ok, that's it. Tessa Bot, stand up," I commanded. 
     
    "Yes, Master Tessa Bot hears and obeys," she droned. 
     
    "Jen, you lay on the bed on your back. Madison, you will get on all fours on the bed and eat Jen out until she has an orgasm, and then you will switch places with her, and Jen, you will eat Madison out." I commanded. 
     
    "Yes Master!" They both said giggling and got on the bed, removing their panties. 
     
    "Tessa Bot, take this paddle and spank whichever brat is eating the other one out; make it firm but not painful, do you understand? You will only stop after each of the girls has had four orgasms, or if I tell you to stop." I commanded. 
     
    "Yes, Master Tessa Bot will spank these brats asses until they have four orgasms and then stop." She droned as she grabbed the paddle and positioned herself behind Madison. 
     
    "For slaves, you two certainly talk back a lot, so now you get punished and no sex from me!" I said. This jerked both of their heads up, leaving disappointed looks on their faces. Then, without warning, Tessa Bot paddled Madison's rear with a solid "thunk," causing her to moan and cry out. 
     
    "Now both of you thank me and get to it!" I said.
     
    "Thank you, Master," they said together and resumed their tasks. Meanwhile, I went and grabbed another coke from the fridge and sat and watched the show, getting hard again watching them go through the orgasm punishment cycle. 
     
    Finally, it was over. I ordered Jen and Madison out of the room. I decided I wanted to finish my time with Tessa alone. I took her out of her Tessa Bot persona by saying, "Tessa Bot, sleep.".
     
    "That was wild, Master! I was aware of what was going on but was unable to control my mind or body. That was so freaking hot!" She gushed. 
     
    "I'm glad it was good," I said. "Why don't you get on the bed? I'm going to fuck you properly, and I want to grab an hour or two of sleep before morning."
     
    "Yes, Master, please fuck me!" Tessa laughed and hopped on the bed. I dove onto her and had a much more playful and fun roll in the hay. When we were done, she curled up to me.
     
    Before I drifted back to sleep, I thought that now that I have seven girls, I only need one more to apparently have access to more powers and magic.

(*) wanted to close the chapter on this first phase of the story with Tessa joining the group. I am going to try and get a pole up before the 9th on who we want our last girl to be part of the main harem. Thanks for reading and hang in there for the second phase and possibly a new story from me!
