Subject #1: Amy

Sleep didn't come easily. I was far too anxious for the next day. There were two possibilities I assumed might happen. Either the bike worked, and I would suddenly have the power to make all of my darkest fantasies a reality. Or absolutely nothing would happen, and I'd have to bumble through being a personal trainer after spending thousands on equipment. "I really need this," I brooded over the thought of returning to everyday life. "This is the first time I've felt motivated in months." I eventually fell asleep, though. My dreams were full of sexy girls kneeling at my feet with pure desire and absolute obedience in their eyes.

The next day I decided to work my complete shift. I easily finished my entire week's worth of work in 9 hours. The rest of the week, I would send out my already finished work in the evening and respond to emails. With my work out of the way, it was nearly time for my first personal training session. I excitedly went to the garage and set up the bike. The night before, I came up with the framework of a plan for a decent test. I would first do a test run with very few commands and a short duration of programming setting. This would allow me to safely determine if the memory erasure function worked. I set the duration to 0.25 hours. Surprisingly, the machine accepted a fraction of an hour as an input. I left everything else on the default settings. It wouldn't be wise to go too far yet.

Just before 8 pm, I toggled on the arousal and mind control mode as two headlights lit up my driveway. After quickly closing the programming menu, I put on my best fake smile and walked to the garage door to greet Amy. She exited her filthy black economy car wearing grey yoga pants and a pink long-sleeve workout shirt. Her long blond hair was done up in a ponytail. It swished from side to side as she energetically walked up to my garage to greet me and escape the cool winter air.

"Hi, I'm Amy," she spoke in a nervous, shaky tone. "You must be David."

"Guilty as charged!" I replied with a slight cringe at the poor choice of a lame joke, "welcome to my humble gym and garage." I gestured for her to step in. "It's a pretty decent set-up, and I can change your car's oil in here after your session for a small fee too."

Amy giggled briefly at my attempt at breaking the ice. "It really is a fancy home gym, though." She said with sincerity as she stepped into the garage and put her water bottle down in the corner.

"How about you follow me in some stretches and tell me your goals for this training." I pointed to a pink yoga mat I had set up for her. She complied, and we sat down as I led her in the same stretching routine I had ingrained in my memory from years of running track.

"Well, life has been pretty turbulent the last few months, and I really need a new hobby to get my mind off things. ya know?" She began talking as she carefully mimicked my movements. "So... mmm.. that's a stretch... I decided I should try to get into better shape and maybe make my butt a little nicer." She said with a slight blush. "I'd like to get back into the dating scene with a little more to brag about."

I glanced at her ass in one of the wall mirrors as she stretched and smirked, thinking, "you should have started working on that years ago, and maybe you wouldn't be single now." She wasn't flat, but she definitely had work to do. I was pleased she was single, though. That makes things much more manageable.

We chatted for another few minutes before I got up and suggested we start with some cardio. So I led her to the MC1000 and raised the seat to the 5'-7" mark on the seat post.

"This thing is really nice!" She exclaimed as she sat down on the seat. "I didn't know Pelotonne had competitors, but I guess they do!"

"Yeah!" I said with a glint in my eye, "this bike is supposed to have some very special features. I hope we can try them out together."

She started pedaling slowly but quickly stopped as her breath caught in her chest and her knuckles turned white, grasping the handles.

The way she reacted was not dissimilar to the reaction of a girl when you try to touch her over-sensitive clit after an orgasm. My heart was pounding at the possible prospect that this bike was working. "Is everything ok?" I said with mock concern. "I can lower the resistance setting if it's too heavy for you."

"N...no, I can do it. It just felt..." she stumbled over her words as she gathered herself. "Interesting. I'm just going to go for it!" She started pedaling hard. Her eyes closed briefly, and she gently bit her lip as a strange, suppressed feeling spread through her body. A spiraling graphic appeared on the touch screen of the bike. Amy's eyes lazily traced along with its spin. As her pedaling increased, the spiral sped up too. Finally, after several seconds of determined pedaling, Amy's brown eyes became glassier and glassier. Suddenly, the bike's seat slightly angled itself upward and subtly changed shape to push more directly on Amy's crotch.

I watched as Amy's masked pleasure and determination clearly changed to unbridled need and pure instinct. Her face flushed red, her mouth parted slightly into a small O, and she began getting noisier and noisier.

"Oh... my... mmmm," she began to moan as I quickly hit the garage door close button on the wall. "Yes! Yes! Yes!"

"If I didn't know better, I would say you were cumming over and over," I said to her as I watched in awe. "How does this technology exist?" I stroked my painfully hard cock as I watched the single hottest thing I had ever seen. I had fantasized about seeing a girl mindlessly and endlessly cumming her brains out but didn't think it was actually possible.

After maybe a minute more of her unwitting possible self-enslavement, Amy arched her back and screamed in ecstasy, "oh MY GOD! PLEASE! Mmmmmmmmm."

The screen on the bike flashed red rapidly during the entire length of her massive orgasm. Her pedaling slowed to a walking pace, but her blank watery eyes never blinked or left the screen on the bike.

I slowly walked closer to the bike. "You're really hypnotized, aren't you?" I asked Amy in disbelief. She didn't respond or give any indication she heard me at all. I gave her a closer look. I would have said she looked average, maybe even plain Jane, earlier, but now she looked mind-blowingly sexy. I stroked her hair and removed her hair tie, letting her shiny natural blond hair drape down her arched back. I traced my fingers down her spine until I cupped her small but firm ass. I gave it a firm slap, and she didn't respond at all. Moving back to her front, I noticed a small amount of drool beginning to escape her still-parted pink lips. It was kind of sexy in an unusual way, probably because I was the one that tricked her into this state. I grabbed at her chest, but her sports bra smashed down whatever curves were hiding there. "I'll come back to these later," I whispered with a smirk. Finally made my way down to her slightly parted legs. Her yoga pants were soaked to a dark gray. I reached to cup her mound. "Fuck!" I jumped back and cursed as a massive shock shot through my body. "Jesus! I guess there's some electricity involved with this somehow."

Shocked back to the present, I remembered I had some testing to do. Amy kept pedaling slowly as I looked at the screen of the bike.

"Subject acquisition complete! AQ intensity rating 113%. Subject ready to accept commands. State the subject's designation to continue..." was displayed on the green-tinted screen.

"Amy, can you hear me?"

"Yes, master, how may I serve you?" She monotonically replied without moving.

"Oh wow... ok.. umm," I hesitated as my heart threatened to pump out of my chest when she called me master. "I'm going to ask you some questions. You will always answer entirely truthfully.

She didn't respond. I guessed she might only respond to questions.

"How do you feel, Amy?"

"I feel horny and nothing else, master."

"Ok..." I struggled to keep my composure. "What do you think about the bike?"

"What would you like me to think about it?" She replied, still in a perfect monotone.

"You love the bike and will ride it any time I tell you to." I paused a minute to see if she would reply. Instead, Amy just stared blankly ahead. "Now, what do you think of the bike?"

"I love the bike. I will ride it any time you tell me to."

"Do you have anyone waiting to check up on you tonight? Does anyone know where you are or who you are with right now?"

"No, No."

"Well, that wasn't very smart." I thought to myself. "I wouldn't even go to a strange man's house without someone knowing."

I continued questioning Amy. "Tell me what you remember from riding the bike."

"I had an enjoyable bike ride."

"I'll say," I snickered. "Be more specific, did you feel anything unusual?"

"No, I had a perfectly normal, enjoyable bike ride."

I realized the memory alteration function seemed to work fine, at least currently. Unfortunately, I couldn't get much more information from her like this. I needed to give one more command to test how they worked after she got off the bike, but I needed to restrain myself to a couple since I only had 15 minutes to play with.

"Amy, you will strip naked when you get off the bike. You will not redress until I tell you to. I will also ask you more questions after you get off the bike. You will not think the questions I ask are unusual. Get off the bike now."

Amy stepped off the bike and stood beside it. Some life slowly came back to her face. Her eyes flicked to mine. I shivered for a second, thinking she knew what I did, but she quickly smiled, lifted her shirt, and began following her command to strip.

With a sigh of relief, I asked, "how do you feel now?

As she stripped, she replied seductively, "I feel great, David! I'm verrry horny after that bike ride though. I hope you have more... fun planned for us!"
