Just some tweeks before Tina comes home

'Hmm. Making her crawl everywhere is good, but I'm not sure about how I feel giving my future pet so much pleasure.'

"Hey Katy. Are you unable to orgasm by yourself?"

"That's... well, yeah. Ever since I was younger, even when I got right on the edge, it felt like I was trying to tickle myself. As long as I know that I'm the one giving pleasure to myself, I can never reach climax. I tried asking my sister to help me but she always tormented me for at least an hour before she helped me. That's why I was deemed the school slut. Although my libido is pretty normal, my sister tries to embarrass me as often as she can and when I get horny I need to find someone to help me get off to calm down quickly, otherwise not only will I be late for class, but I'll also have to actually crawl in. The embarrassment from that would be enough to kill me!"

As Kate was talking, John got a frown on his face. He liked the general idea, but his pet wasn't a free use one. Other people were only allowed to use her if he said it was okay. He needed to fix this. Even though the simplest method would put her under himself, the funnest one would be a different one.

"Eh? But I thought that your Tina subliminally conditioned you to always reject any sexual advances and never seek them out yourself, with the exception of her and anyone she chooses. She could do that because when you were in high school and only then, as you slept, you were very susceptible to your own voice. And since your sister's voice is identical to yours, it also worked. That's why you're only allowed to have sex with her or me. She also made it so you wouldn't travel more than 50 km away from her. Isn't that right?"

He didn't want to mess with her mind or make her subservient. He wanted to break her pride and have her put aside her domineering attitude herself. To lower herself through her own choice every time she wanted to have an orgasm. The voice thing was just a precaution so that he wouldn't inadvertently give her sister hypnosis powers or something.

"You knew?! Did sis tell you? Why didn't you tell me? You could've helped me out so many times!"

"Well, I'm here now and that's what matters. Also, lastly, just to make sure, seeing genitalia is enough to make you aroused, and the place they touch will receive 3 times more sexual pleasure than normal, right?"

With this, it would be very difficult to fuck her for a long time. If her sister is already twice as sensitive as normal and could already dominate her sexually, that means that when Kate is in contact with genitalia she would probably be so sensitive she'd orgasm in a minute or two. Maybe less. And the orgasms would be Very strong.

"Yeah"

(A sad paragraph ahead, skip it if you want to)

Katy truly hated her life. Little princess Tina could never do anything wrong and she had to get the blame for everything. Even with Tina's constant bullying, and the times she had to cut class in high school because of Tina triggering her arousal, she barely scored high enough to get into uni. When she finally thought she'd be free, she realised that her sister conditioned her to be unable to orgasm without her. Still, her pride told her she needed to get out. But as if that wasn't bad enough, when she tried to go to a different city not caring about whether she'd orgasm ever again, she found out that she couldn't. There was a little voice in her head that told her she must stay nearby. She felt crushed. Still, she tried to make something of herself. She started going to uni, only to realise how bad her sister could be. She would trigger her constantly. As such, she failed and had to flunk out from the first semester. Her parents were extremely disappointed with her and showered praises to her sister for finding a job for her. Tina made it abundantly clear that this was the only job she would let her do. It was scrubbing the toilets for the campus buildings. Although technically part of the cleaning crew, instead of having a section of her own, she would not sweep or do other miscellaneous things. Just the toilets. Which were often filled with vomit and always filled with bad aimers.

And whenever she came home, she was 'greeted' by her sister. When Tina was in a good mood maybe she would actually ignore her. Most of the time she humiliated her through and through though. As if that wasn't bad enough she would think of different embarrassing things for her to do every once in a while and try as she might, because of her damned pride, she could never get used to them. She remembered once when Tina apparently had a bad date night with some girl, she tied her down with vibrators on her feet so that she wouldn't orgasm for half a day. Then, as she was delirious from pleasure she told her to stick a remote controlled vibrator in her vagina and go for a walk to the park. Due to obvious reasons she had to crawl there. Being seen by everyone like that was both humiliating and embarrassing. When they finally got to the park she saw that one the few friends she managed to make was there and shirked back. Tina tried to push her forward when her friend saw them and approached them thinking that she stumbled and fell down. Her friend reached out a hand which she tried to take and stand up. Her crimson red face made her friend think that she was ill at the beginning but when her friend helped her up she was that Kate had a huge wet spot in her crotch area. When she freaked out and asked about it Kate felt like crawling in a hole. But then something horrible happened. Her sister stepped forward and said not to worry about her.

"Kate is just a huuuuuge pervert and she does these kinds of things pretty often. All she needs is an orgasm. The reason she 'fell' was because she was nearing her climax probably."

As her friend looked back at her horrified, her sister turned on the remote vibrator and everything went blank.

"Oh fu..AAAhh!! I'm gowwnnda- ugh, (swift breath)ahh, (swift breath) aHH, (swift breath), GOD, I caun't!! Imma- Arghh!!!"

Kate tried minimising her screams as much as possible but it was impossible. Not only had she been teased for half a day before, she was paraded crawling toward the park and now shown in front of her friend in this miserable condition. Her sister's words reverberated inside her head as the constant feelings she got when she tried to stood up before attacked her. The vibrator was like a key unlocking a dam. She fell to her knees and started spasming. Even as she tried to suppress her voice, it was still loud enough to draw a crowd and the fact that she tried so hard meant that not only did she flail around but she also pissed herself. Not only that, but the embarrassment from what she was doing compounded with her orgasm pushing her even further making her faint for a while. When she was through, her sister had already turned off the vibrator, but she was still surrounded by random onlookers. Her friend was nowhere to be seen and she never spoke to her again. Her face was a mess of drool, snot, sweat, and tears from the orgasm, and she could still feel aftershocks. To top off her absolute humiliation, the onlookers had made her embarrassed enough that she couldn't walk, so she had to crawl back home. She was truly miserable.

Meanwhile, John thought that this was enough. Time to clear the initial command

"Well, you don't actually know me that well though for you to completely trust me. After all, I've only been here a few times since Tina asked me to come. She loves me so much she'd pretty much do anything I asked her to, and since she knows I'm pretty dominant she thought I'd enjoy meeting you, so I came to talk to you a few times before deciding how to treat you. Isn't that how things happened?"

"Oh,hmm, yeah, sorry. So, did you decide how you should treat me?"

"Of course I ha-"

At this moment, the door opened and Tina came in.
