Not yet. Erica and Greg relax together first (PISS)

Erica falls exhausted on the sofa, recovering from a second time that I have **** her to reach the edge of orgasm without getting it.

At that moment, she notices that Freya has also stopped fingering herself. She saw the same look of a woman horny and needy for an orgasm that won't happen, and probably it is even worst on Freya than my sister.

"Brother," she asks me, "you actually won't let her cum too? That poor thing has been through more than me, three weeks."

"I am glad you finally call another woman a thing instead of a person."

"No! I didn't mean that! It's a way of talking !" she replies, embarrassed. She probably didn't mean it, but that doesn't imply I won't tease her a little, right?

I know what Freya wants, but my sister still believes I am the one who is forcing her. To make her understand that Freya is voluntarily giving away her orgasm for me, I whisper to her, "Ok, fine, I'll allow it. Why don't you tell her?"

"Freya. My brother said you could cum. Please, do it. It seems you needed it."

"With due respect, Mistress. I refuse." Freya responds immediately without hesitation.

"Why?! I don't get it!" Erica asks, confused by her answer.

"Mistress. I want to please our Master. And I feel my orgasms are an impediment. I choose not to cum so that I can focus on Master's pleasure instead of mine."

"And how much time will you be without cumming? Once a week? Not because you told me it has been three weeks once a month?" She pauses for a second, but Freya doesn't give her any answer. "Once a year?!" Erica adds, assuming the lack of a response could mean a longer time. There is another option that has not yet crossed my sister's mind.

"I don't know yet," Freya finally responds. "For now, I feel I still don't deserve it. Sorry, Mistress, I can't give you an answer."

This will make her look at her own orgasm denial from other perspectives.

"Brother... Can I..." She has an embarrassing look on her face. "Can I...use the toilet?" Of course, she has already asked me every time she needed to pee in the last two weeks, but this is the first time she has asked me in person.

"Be more specific."

Her face is totally red, but she knows she must say it. "I need... to pee."

"Sure. Where do you prefer to do it?"

"What do you mean where?"

"You can use my litterbox, Mistress." Holes tell her.

"Do you use a litterbox instead of a toilet?"

"Of course, Mistress!" Holes affirms. I would even say that she is a little indignant about questioning it. "I am an animal, duh."

"Well, it really doesn't surprise me. Still, I prefer to use a toilet, thanks."

I actually didn't want her to use the litterbox, but it has been fun to try it. "Ok, let's go to the bathroom," I said as I start to walk into the bathroom, holding my sister's leash in my hands. She follows me, still with her hands on her back.

"I suppose I don't have the right to privacy, and you will watch me pee," she asks me or rather confirms herself because she already knows the answer.

"You suppose well. I do not believe in any women's rights, including privacy. You will do it in front of me."

She doesn't comply. At this point, she knows that would be useless. She is starting to accept that obeying me is the only option.

She had been so worried about how to pee in front of me that she didn't notice that Freya has followed us into the bathroom. I make my sister turn around, and once she does it, she finds Freya kneeling in front of her.

"What is she doing?" She asks me once she sees Freya.

"Freya, tell her what you are."

"Mistress. I am a urinal. I drink Master's piss, and I could drink yours too if you want."

"I am not sure..."

To help her accept it, I grab Freya's head and open her mouth with my hands, which she did with no complaints. "Look, sister. Once you pee in this cute mouth, you won't want to do it again in a porcelain urinal."

"Yaaa... Mastress... Usa mah..." Freya tries to add, sounding unintelligible with my hands holding her mouth.

I want my sister to use other women as urinals, and once she accepts that women could be a urinal, I will also convince her that she could be a urinal too.

"This is too much, Brother. Can I use the porcelain toilet this time?"

"Don't tell me. Tell her you won't use her." I insist, still holding Freya's mouth.

"Freya. I am not ready to use you. I will think about it for next time, ok?"

I let go of Freya's mouth so she can answer her. "It is ok, Mistress. But next time, use me. It is a promise. At least let me clean you when you finish. You can't use your hands."

"Yes, you can clean me."

I help my sister to sit on the toilet, the porcelain one, not the human one. She immediately sits with her legs closed, trying to avoid giving me a good look, but I make her open her legs with my hands. Meanwhile, Freya kneels in front of the toilet with her hand in the bowl between my sister's legs, having her cunt at the same height as Freya's head.

My sister cannot look at Freya due to embarrassment nor me, so she keeps her face looking to a wall to her left and her eyes closed. I am her right, looking at her crotch while I take the opportunity to grope one of her tits.

We wait for a few seconds. She is trying to let her pee come out, but it is hard for her with both of us looking. A few drops come out, but then it stops. She did the same a few more times until she finally let all the flow come out.

Finally, I see my sister fully pissing. The piss flows without stopping, bouncing off the toilet bowl, and some drops hit Freya in the face, but instead of turning her head away, she opened her mouth instead, intending to taste some of it. Freya has become a well-trained urinal.

Once her bladder is finally empty, I make my sister get up from the toilet. Freya steps away, licking her lips, ready to start cleaning my sister.

She first licked my sister's left leg, where she was leaking a few drops of piss.

"Wait, wait! Freya, what are you doing?" Asks Erica, surprised by the way Freya is cleaning her.

"Cleaning you, Mistress." Answers Freya, without stopping licking the drops from my sister's legs.

"You have agreed to let her clean you," I remember her.

"But I thought she would use paper!"

"You have agreed to let her clean you or not? Answer me like a lawyer. Does any of this contradicts what you have agreed with her?"

"Well..." She doubts for a second, but she knows I am right. "You are right. I have agreed to let her clean me. She never said she would use paper. She is doing her part, so I can't complain."

Erica stops complaining and lets Freya continue cleaning her. Once she has licked all the drops from my sister's legs, she starts licking her cunt. To ensure she doesn't let any drop, she opens Erica's cunt lips also to clean her inside, not allowing any point without licking, including her clit. Thank the two previous edges she had. It only takes a few seconds for my sister to start moaning again.

"I can make her bring you to the edge of orgasm if you want."

"No, please." My sister pleads with me.

"Ok, fine."

"Please turn around, Mistress," Freya asks Erica, wanting to clean her behind. Once my sister has turned around, Freya starts licking her glutes not to let any pee drop. There are not so many drops there, but that won't stop Freya from being thorough on her job. Last, she separates my sister's glutes to lick her asshole.

"I not sure if I need you to clean that part, Freya," Erica says, trying to stop Freya from licking her asshole.

"She wants to do a good job, Sis. Let her lick whatever she considers appropriate."

"Done. You are clean, Mistress." Freya tells us.

My sister is unsure what to say now until she finally replies, "Thank you, I guess." I don't mind her being polite with my other toys.

Once we are finished, I take my sister on her leash back to the living room and make her sit again on the couch.

At this moment, Binita came from the kitchen with the drinks I had asked for. She left the tray with the drinks on the table, with glasses for everyone except for Holes. For her, she has a bowl of juice that Binita lets on the floor.

"Don't tell me." My sister said, referring to Holes. "She drinks and eats on the floor because she is an animal."

"You are right."

"It is degrading. But she didn't seem to care."

"Of course not, Mistress." Holes confirms her with a smile. " I love to be Master's pet." This will help my sister accept that submitting is not bad and makes women happier.

"Hey, can I use my hands now? If not, you will need to help me drink mine."

"You can move your hands. You only need to keep them on your back when I move you with your leash, or I command you to do it."

Since my sister entered my house, she can take her arms off her back for the first time. Once she has recovered from being this time without moving them, she is ready to start drinking.

"Thank you for the drink." My sister thanks me while grabbing her cup. "Oh, pineapple juice. Great!"

I expected her to grab her teacup, but instead, she takes the pineapple juice prepared for Freya, but the juice the girls drink is mixed with piss. Before I can say anything, she starts drinking it. I should stop her because I promised not to **** her to drink piss, but now that I think about it, I have not **** her to do it. I told her Binita would make tea for her. Taking the piss juice is her fault; I can take advantage of it for her training.

"Mistress," Binita says, pointing to the juice my sister is drinking. "That juice was for Freya. For you, I had prepared a cup of tea."

"I am so sorry." My sister said, giving Freya the juice glass she had drunk.

"I don't mind, Mistress. If you want it, you can have it," Freya adds.

"Don't worry, Mistress," Binita calms Erica. "I will make another one for Freya."

"Do you like it?" I ask my sister.

"Well... yes. It has a bitter taste, but unlike some weirdo I have for a brother, I like juices, especially orange and pineapple ones, to be bitter instead of sweet."

"You won't forget me for adding sugar to every juice, right?"

"Nope." She replies, sticking out her tongue. "Degrading and humiliating me is one thing, but adding sugar to the orange juice? I won't ever accept that."

"Ok, ok, maybe I am a monster for drinking sweet juice." I can avoid letting a small laugh. "But if you like it, I can make Binita prepare a bottle for you. She made it with a secret ingredient that makes it bitter."

"That's great." My sister said, smiling while continuing to drink the piss juice. "Thank you, brother."

After all, she didn't drink her tea, only the piss juice. The three girls also drank their juice, and I drank a cup of tea. Once we finished, I made the girls go to other rooms to do other things to let us alone, my sister and me, relax.

We watched a comedy movie on Netflix. She stayed by my side the whole time, repeatedly putting her hands on my leg and chest. I kept one of my hands on her shoulder to keep her next to me, but from time to time, I used my hands to grope her tits, pinch her nipples and rub her cunt, so she won't stop being wet and horny. She let out little moans from me, but she never complained. She let me do what I wanted with her all the movie.

Once the movie finished, she already placed her head on my chest. At this point, I open my zipper and let out my dick, already with a hardon. She is still horny and denied, without stopping looking at my cock, expectant for what I want her to do.

"I have been masturbating a lot those two weeks thinking about this cock." She tells me without stopping looking at it.

"And I have masturbated many times over the years thinking about you."

"I am deligthed to hear it."

"But I don't masturbate anymore."

"Because now you use women, right?"

"That's right."

"So, I suppose that means I should please you."

"That is what I want."

"Yes, at least I owe you that because you had allowed me to cum this past two weeks. How can I deserve to cum If I refuse to make you cum first?"

"I am glad to know that you are not greedy."

"Greedy? Against my brother? Never. I want you to cum as much as I want to cum myself."

"Only the same?"
