"Hi babe. Yeah, another long day for me today. They got me working so hard on this new project. No, I'm alone in the office," I said through my earphone.

My wife on the other line was starting to get worried that I've been pulling long hours for the past week. I work for NexusCorp and I'm part of the SWAP team project, working on a new device that will revolutionize the world, incidentally it could also change reality itself. As the head engineer in this project, it was my duty to test the device and ensure that everything worked fine. The test started with mice, then sheep. There was couple of tests that didn't go accordingly, so in a panic, the company deemed it unsafe and shelved the project indefinitely.

I was quite confident, being the person that worked on it the most, and I decided I was going to test it on human subjects, against company policy. In particular I wanted to test the device's functionality to allow the user of the device to condense their whole being into just their head and allow it to replace another humans head. For example, if I was the user and I fired the device and hit another human, my head and consciousness will replace theirs, while they go into suspended animation. This will allow the user full control of the other's body.

I made sure to select a subject that would not be missed incase of any issues with the device. Some one who is single, haven't spoken to family in a long time and tended to keep to themselves. In came Mia, our intern. She was quite the loner, pretty weird and was into tattoos. Throughout the course of several days, I got to know her and found that she lived by herself downtown, no boyfriend and her family lived all the way in the UK. She was also relatively new to the US, so did not have many friends.

When everyone clocked off for the day, I asked her to stay behind and help me test the device, not really knowing what she was in for. Of course she agreed, thinking that this may help her secure a full time position with NexusCorp. I had her start working on a prototype which did not work, whilst I stood behind her and fired the real device. There was a moment of blackness, then I found myself bent over the table, heavy weights pulling down on my chest.

After the initial shock, I looked down and marveled at my new body; Mia's body. I instantly grabbed my breast, and traced my hands on each curve of my body. The nipples on my borrowed chest hardened immediately and for the first time ever, instead of a hardening sensation, I felt dampness and a deep heat in my crotch. I ran towards the bathroom and stripped out of Mia, basic business attire. She had a banging body, but decided to hide it as she also tried to cover up most of her tattoos.

After my lengthy exploration of my new found womanhood, I decided it was time to hit reset. Before that though, I coded in some commands into the device to try to imprint into Mia to wear more revealing clothing. I placed the device on timer, behind Mia, and got into a similar position she had taken before I took over. The device zapped me again, and I re-materialized next to the device. Mia shook her head and I went over to see if she was okay. She was confused, but I just said, "Time flies when you're having fun aye?"

Throughout the next couple of days, I observed that she had indeed started to wear more revealing clothing. My experimental code was a success. And everyday at 5pm, I would ask her to help me test more of the device and I would take over her body and explore, i.e. masturbate in her body. It was so thrilling. Each time I would code in new commands, to make her think she was working on the device during the times that I took over. Today she was she was wearing a small black dress, that showed of her curves and a black thong. I sat on my chair, fingering myself, as I spoke to my worried wife. A moan escaped my lips.

"Huh, no babe, I'm not moaning. I'm just so tired and was stretching. Sitting all day is killing my back," I said as I plunged a finger into my pussy. "Ah huh, yup. Now that you mention it, I miss you so much. How about we try out phone sex? No ones around. Come on babe, describe what you want me to do to your body." I told my wife. My wife agreed, feeling a little naughty and started describing what she want me to do to her, to get her off. As she described it, I was doing the exact same thing to the body below my neck.

"Oh yeah babe, you want me to grab your big tits and pinch your nipples gently?" I asked, as I squeezed and pinched my own nipples.

"I'll run my hand down your smooth stomach and lightly touch your clit. Yeah baby, I'm rubbing your clit gently babe, uhh, do you like that?" I moaned as I rubbed my clit as well. I was so lost in the phone sex, that I did not notice a masked man enter the room. He saw the device and swiped it from the desk behind me, quietly exiting as I was about to reach orgasm.

A few minutes later, I hung the phone up and was going to hit reset on the device, only to find it missing. My heart sunk and I rummaged through my whole office to try and find the device, tits flailing around and all. The device was long gone. I grabbed my tits and looked down. "How am I going to explain this to my wife?"
