Two weeks later (PISS)

That day class was again dull, as usual. I didn't even have a class with Caitlin; at least her classes are more interesting now that she subtly defends female inferiority.

And the edge punishment for the girls? They failed. When I returned home to eat, Binita told me she could only cum 14 times, while Freya and Holes had 14 edges. As a man of my word, I made those two to edge all day until they accumulated 30 edges, not allowing them to cum a single time.

For the next two weeks, I just let my sister continue with her masturbation session; I have not pushed her to do more things with me, to let her exposure to **** porn take effect, so she no longer thinks the idea of having sex with me, her own little brother, is a disgusting act.

Two weeks later, she no longer pinches her nipples even a single time when she is masturbating one hour a day, which I am the only man that crosses her mind when she does it, not even Jeff, her boyfriend. And the intensity of the porn used has increased day by day; she no longer reduces her intense touching no matter how nasty it is; all the things I told her she would do with me are things that at least I can see turn her on, it is just a matter of time that I can make her do it with me in person. Even one time when I told her to cum with piss drinking porn, she didn't have a problem; seeing this porn no longer provoked her disgust. She will need more training to do it, especially for the smell and taste, but at least she is curious about the idea of drinking piss.

I kept my promise and allowed Erica to keep seeing her boyfriend, Jeff, one or two times a week, but as I also promised, only platonic, she is only allowed to kiss him, and she must not make it too passional. Erica no longer has sex with him, nor can Jeff see her naked body, even though he has no clue that my sister no longer wears panties. He doesn't seem to comply, which means that the APP was not lying that only she and I could break that relationship. Probably he wants to comply with her, but he is not able to do it, but of course, I don't care what he wants, my sister belongs only to me, and I won't allow anyone to question it. Jeff could be grateful that I kept my promise to Erica not to **** her to break their relationship.

Freya and Holes no longer fight with each other. The edge punishment took effect. As I told them, they play with each other to strengthen their relationship, and even though the first day I could see they just were **** to do it, now they both look happy when they spit on each other mouths or lick each other cunt and ass. The same happens between them and Binita. Now the three girls are three **** sisters who collaborate to please me.

Professor Caitlin also plays with them when she comes to my home. She continues pushing anti-feminism ideas in her classes in a very subtle way. It is so subtle that even some feminist College girls believe the professor is faking it to teach them a lesson to defend feminism better, as she foresaw. Caitlin is openly anti-feminist, pretending to be a feminist that is pretending to be anti-feminist.

Half of the days, unless she has a lot of work to do, she expends the nights at my home; after all, I want to have her available to fuck at any time like any other of my slaves. The first day was a problem because there are only three rooms at home, the main room for me with the big bed, and two rooms with small beds for Freya and Binita, while Holes slept in a dog bed in my room. That doesn't mean I would allow Caitlin to sleep on my bed; that privilege is only reserved for my sister, so the first night I made her sleep on the couch, and after that, I made Holes use her father's money to buy two more beds for the girl's rooms, so Caitlin had where to sleep. The other one is for Becca, for the day I officially make her my **** and move her to live with me.

About Becca, well, surprisingly, she has not yet asked me to control her orgasms. She talks with me almost every day, even openly sharing with me the porn she likes more when she masturbates and how she wants a boyfriend. Of course, she has not found a boyfriend because she can't talk to any other man. Soon she will realize she can't speak to men because the only one that could be her boyfriend is me. But she has not openly asked me to cum, and that isn't because she has not found orgasm denial porn because she has shared some blog posts about women not being allowed to cum with men. By now, she must have been a week and a half without orgasms. Maybe it's because she was very inexperienced before being captured? Probably she didn't masturbate too much before that, so she is not used to cum, and therefore she can be all this time without release.

Freya has also been this two weeks without orgasms. She is constantly masturbating, every time I check on her, she is wet between her legs and even looks **** to cum every time I fuck her, but every time she can hold it back and ask me not to allow her to cum.

I am starting to think that Freya will be my first **** that becomes a permanent denial slut. And Becca is probably going the same way.

The piss training is also going well. After the first week, I started to piss directly in Freya's mouth, with no juice. By now, all the morning, she is ready, waiting for me in the bathroom to be my urinal. The first time she **** a smile while doing it, she can now genuinely show me a happy smile when her mouth is full of my piss. Sometimes even the girls have used her as a urinal.

That doesn't mean the girls any longer drink juice with piss. They still do it, even Freya. Of course, because I piss directly inside Freya most of the time, I cannot fill many bottles with my piss so Binita can make the juice. To have an alternative, Binita uses her own piss and Cailin's piss. Holes one can't be used because she does it in a litter box like the animal she is, and Freya's can't be used too because the piss from someone who mostly drinks piss could be too acid, and I don't want them to have health issues. Binita and Cailin also drink some, so to avoid problems, I told Binita to never go over 50% piss on the juice she made, so the girls who drink it could be fully hydrated with the water inside the juice.

Today is Monday. Now, it is time to take my sister's training to the next level. To prepare her, I have not allowed her to cum a single time last weekend. If she wants to cum she must do something more than just let me watch her masturbate.

G: Hi, Sis. How are you?

E: Horny. You have not allowed me to cum since Thursday.

G: I know.

E: When will you let me have release?

G: Why? Are you ****?

E: Yes! Before you captured me, I could stay one week without sex or touching me, and that wasn't a problem. But since you started making me masturbate many times a day, my sex drive is going up the roof. I need it.

G: That was my intention. A woman should be ready to be used any time her owner wants. That is why I make you always be horny.

E: It is all your fault that I am always horny, but I've even started to like it.

G: Good. What will you do today after work?

E: I will have dinner with my boyfriend. I'll send you the address of the restaurant. Do you authorize it?

G: Yes, authorized.

E: Thank you, brother.

G: But I can propose you an alternative.

E: I am not sure if I will like it.

G: Oh, you will. You can have dinner with your boyfriend or come to my place.

E: If I go to your place, will you allow me to cum?

G: Clever girl. If you please me, yes, you will cum.

E: If I have dinner with him, when will you allow me to cum?

G: Probably in a week.

E: A week?

G: You choose.

E: Fine.

G: Fine, what?

E: I will go to your place.

G: What will you tell your boyfriend?

E: I will tell him I have so much work so I can't go out tonight.

G: Have you used that lie before?

E: Well, sometimes it has been true. As a lawyer, I have so much work, but yes, sometimes I have used it as an excuse to avoid going out when I don't want to.

G: You know you can't do that with me, right?

E: Of course. Because I should obey you, no matter what I want.

G: Good. Once you finish working, come directly to my place.

E: Oh, I closed my laptop as soon as you told me to go to your place. I am already on the elevator to take my car.

G: Haha, you are really, really **** to cum.

E: Yes!

G: Good girl, sister.
