Miyu rolled onto her side and stroked my tummy, then ventured further. My legs were parted so there was no barrier to her wandering fingers. She kissed me gently on the lips and simultaneously stroked my labia.

"I'm sad when you're not smiling, Mistress," she said before pushing her long black hair off my face.

I thanked God that Toshira hadn't gone through with his plan to implant a microcomputer into her skull. She had the right brain for the procedure, but she was nowhere near tough enough to cope with the stress of losing control. I argued with him endlessly and finally struck a deal so that he wouldn't pursue the idea.

Doctor Miyu Masaki had been my assistant for three years and lover for the last six months. Brought up in a convent, the girl had lived a sheltered life but had received a fantastic education, getting her medicine degree at the age of 22. Three years later, I was proud to think I had deepened her understanding of the link between medicine and artificial intelligence.

That was my field, Microbotics. Our work had taken us together into an area I hadn't expected when I joined Sasaki Industries. We ended up spearheading their quest to produce the first fully functioning Integrated, Luxury Living Space, complete with Uni-Dolls and Companion Dolls.

We worked together in Silicon Valley and everything I had achieved wouldn't have happened without her help. When I got the credit for developing the X5 Neon microcomputer, Miyu took it gracefully and was quite happy to stay in the background.

I lifted my head and kissed her on the lips. "It's hard to accept that our brief time together in this apartment is nearly over."

She teased my lips apart and started playing with my clitoral ridge and clit. Having my pussy modified, had proved to be a godsend and provided me with a great deal of additional pleasure. Miyu, despite my misgivings had the same package of modifications, including breast and buttock enhancements.

That was one of the reasons why Toshira was keen to implant an X5 Neon microcomputer into her skull. The other reason was that she was gorgeous and would make a stunning Companion Doll.

"I.L.L.S. and the suite are ready for Iku's and your upgraded Doll, Miss. Once the investors have visited, we can go back to California."

"I know, Miyu. It's Toshira I'm worried about. He's bound to want us to stay longer while he's in Sendai."

"I don't think so, Miss. Now the Sasakii Tower project is nearing completion, Toshira will turn his attention to Dubai."

It was true, Toshira had at least a dozen developments on the go and Dubai would be the next one to complete. "Dubai might be months away..."

We had to get the Sasaki Tower installation running smoothly, complete with its own Uni-Doll and Companion Doll. That was why I had made the trip to Sendai to hurry things along. Unfortunately, I had to stay until the investors had checked out the Integrated Luxury Living Space for themselves. We were going to move into an apartment in one of the accommodation blocks, well away from Sasaki Tower while that happened.

"I know you're anxious about the sex Doll's data being uploaded onto I.L.L.S.'s memory, Miss, but without it, we won't be able to trial the system."

It was a shame Toshira felt the Companion Dolls associated with I.L.L.S. had to double up as sex Dolls. I felt it tainted the whole project.

"Now that Hills has that capability, Miyu, I'm vulnerable while I'm in the building," I explained to my lover.

I volunteered to have my own microcomputer implanted on the proviso that I controlled its programming. That was fine until Sasaki Industries demanded that Professor Fujita be allowed to produce deluxe companion (sex) Dolls, using the X5 Neon from the company's base in Sendai.

S.K.I.'s normal static sex Doll models were a huge success. I was surprised when Toshira broke the news to me that they had tasked Saburo with producing fully functioning companion Dolls; and I was furious that my microcomputer was going to be used for them to function. However, I calmed down when Toshira promised that my work on Uni-Dolls wouldn't, in any way, be connected to his work.

All the data that Hills had been collecting from me during the previous seven days, while I lived in the suite with Miyu, had been invaluable for the Uni-Dolls and future Companion Dolls. Adding Companion Dolls to the Integrated Luxury Living Space program was a late decision and required a lot of re-programming to make it happen.

I had to explore every inch of the top two floors of the tower and some of the penthouse apartments on the sixteenth so that Hills could control any Dolls working in that space. My efforts had successfully put 18 Uni-Dolls to work on the three floors and we had arrived at the time to introduce Companion Dolls when they became available.

I allowed Hills to put me into command mode, during set times and activate a couple of the commands the professor had uploaded into Iku's memory. I was dying to meet the youngster who was the second recipient of the X5 Neon and see how she coped with following such a perverted set of commands.

Toshira was due at ten o'clock and was going to arrange for us to meet the professor and Iku sometime during the day.

I looked at the clock and saw that it was 8:55. "What have you got lined up for me this morning, Miyu?"

"Seeing as it's our last day in the apartment, I programmed something special."

"Don't tell me, I'm making your breakfast..."

"No, something a little more exciting."

I had a couple of minutes before Hills put me into 'command' mode, so I rolled off the bed. "I'm just going to do a wee."

I padded through to the bathroom and sat down on the marble pan to relieve myself. I was just dabbing my ass when the slight dizziness that signalled loss of control washed over me. I stood up and walked through to the bedroom.

Miyu, naked, was standing with her arms by her side. In her right hand she was holding one of the small dildos we had been playing with during our stay. "Hello, Mary. Have you finished in the bathroom?"

I bowed. "Yes, Master, I have." We had programmed Hills to make me call everyone Master, just for the trial.

"Good. Mary, I want you to make my breakfast and put it on the dining table. I then want you to bend over the table and wait for me to arrive."

"Are you going to use one of my holes, Master?" I inwardly winced at the crude language that was so necessary when making interactive sex dolls.

She lifted the dildo and waved it in the air. "How did you guess, Mary? Now, do as you're told and make my breakfast."

Miyu was making the most of our last chance to play Master and submissive. Neither of us were particularly imaginative when it came to male/female sex acts. We preferred to stimulate each other with our fingers and mouths.

Toshira's demands for sex were another matter, but I made sure he never went beyond what I would call 'normal' vanilla behaviour. His advances were becoming more frequent though, as were the threats to give Miyu an implant. I loathed the man, but I'd do anything to keep my lover out of his hands.

My focus was getting the I.L.L.S. project up and running and then leaving as soon as possible for California, with Miyu. We were safe there, even when Toshira was moping around.

I left the bedroom, walked down the hall to the kitchen and went through the routine I had been practicing all week. I was very aware I was naked as I poured cornflakes into a bowl. My large breasts and chunky nipples were always in my peripheral vision, a complete contrast to the small tits I had before I went for the complete, enhanced package.
