Erica will masturbate in a video call with her brother

This is the perfect moment to make a video call with her. She accepts the call without hesitation. I am unsure if it is because she is **** or because the APP makes her unable to ignore my messages and calls.

"Hi, sis. How are you doing?" I tell her with the camera pointing to my face. Meanwhile, Holes is busy sucking my cock, and her sounds are clearly audible through the phone, but she so concentrates on her nakedness that she still hasn't noticed it.

"Let me wear something, please." She told me, with the camera pointing to her face, red with embarrassment.

"Don't be shy. I have already seen you naked. Show me your naked body." She doesn't complain. Just as I give her the order, she moves her camera to show me her body. I can see that her nipples are hard, and in her cunt I can see some wetness.

"Are you wet, sister?" I ask her.

"How can I be? I am naked in the changing room."

"Be sincere."

"Yes, I am wet. Happy? I shouldn't, but every time you **** me, you tell me I am not a person, or just like now that you humiliate me, I got excited."

"Perfect, sis. How many sessions of masturbation do you have left to do today? Excluding the one-hour watching **** porn."

"One."

"Perfect, you can do it in the changing room if you want," I ask her, carefully selecting my words so that it is not a direct order.

"I can't. What if someone hears me?"

"You are fine. This is why I tell you to choose an isolated changing room."

"Fine, tell me to do it. Could you give me an order? That will make things easier for me."

"No, you must do it on your own. It is your choice. But if you don't please me, I won't authorize you to wear any clothes."

I found that humiliation works better with my sister when I make her do something without using a direct order because that way, she is the one who voluntarily does the action. Her humiliation is reduced with orders because she recognizes that her actions are not hers. That is why I give her two options to choose from. She can start masturbating by herself or leave the changing room naked in 10 minutes.

"Fuck...ok, fine."

She pointed to the camera focusing on her cunt while she starts to rub it. "Do you like to watch me doing this, pervert brother? Do you still believe I am just a 7/10 object?"

"No, sister, you are again my favorite 12/10 object. And I am not the only one who likes it. Say hi, Holes." As I told her she has more audience than me, I move the camera away from me to show her that I have Holes with me, listening to us while sucking my cock.

"Hi, Mistress Erica. I am glad that Master finally owns you as he owns me. I can't wait for both of us to serve him together, and I will serve you, too." She didn't wait for Erica's answer before continuing with my cock; she knows what her priority is.

"What? Is that Brooke? I knew that you own her too, like me, but didn't expect this." Erica says, shocked. She didn't contemplate finding Holes on the other side of the phone, much less sucking me.

"Don't stop touching yourself, sis. Look at the phone while you do it."

"Ok," she answers when she starts touching herself again, looking at how Holes is sucking my cock. This time, she also introduces two fingers inside her. "Why is she calling me Mistress? You told her to do that?"

"Actually, it was not me. I swear."

"Mistress," Holes interrupts. "You are Master's sister. That makes you superior to me and every other girl Master owns. I believe it is appropriate to show you respect."

"But he has told me that I don't deserve respect."

"Not for him, Mistress, because you are still a woman. But I am also a woman, and I am below you. Now, if you'll excuse me, our Master wants me to take care of him."

"I think I understand, Brooke."

"Don't call her Brooke, Sis. Now she is called Holes."

"That is so...ahhh," she tries to complain between moans. "Ok, I think I understand...Yes! Holes, thank you."

At this point, I am almost ready. I grab Holes' head and push me deep inside her throat. A few seconds later, I cum inside her mouth. Unlike other occasions, Holes does not immediately swallow. Instead, she shows her mouth full of cum to Erica, and while doing that, she swallows and shows her empty mouth.

"That is...ahh...so hot...Can I cum too, brother?" My sister asks me, ****.

"I am not sure, and I think I want to keep you horny and denied. You can cum at home with your one-hour **** porn."

"Please... Please..."

"Did you like my call?"

"Yes, yes. I love it."

"Fine, you can cum."

She does not need to wait for a second. As I tell her these words, she leans against the wall and starts to come, and her legs are shaking due to pleasure. And also the changing room will require some cleaning. I wait while she recovers her breath before giving her the last orders she must obey today before returning home.

"Ok. I authorize you to wear the same clothes you were wearing before. But only for today. I won't allow you to wear pants anymore. When you are home, throw those clothes away. Well, except for your boyfriend, you will wear pants for him. You are also authorized to wear any clothes you want to try in the changing room before buying them."

"Thank you, brother, thank you, thank you."

"Once you are at home, I want you to give me a show with your new sexy and slutty clothes as if you are a model."

"You will love it. See you later, brother. Kiss. Bye, Holes." Surprisingly, or maybe not, she blows me a loving kiss at the camera. Perhaps she is starting to enjoy the degradation and humiliation.

"Bye, Sis."

"Bye, Mistress."

At this point, I hang the phone. I don't expect her to text me at least until one or two hours, so I was prepared to watch some TV, but surprisingly, Erica writes me a few minutes later, still in the mall.

E: It was so embarrassing. Maybe the clerk listened to me when you made me masturbate.

G: Why do you believe that? Because of the expression on the face?

E: No, I didn't see the face.

G: Why?

E: I couldn't look at his face because he is a man.

G: So, you kept your head lower while paying like a shy girl?

E: Yes, it was what you told me, to not look at other men.

G: How cute. Keep doing it. I can't wait to see the clothes you have chosen.

E: Oh, and for your information, I am going to the toilet to pee. I don't understand why I have a pervert brother that what me to inform him of that.

G: Haha, you will see, Sister. Soon. Authorized.

E: Yeah, my head noises tell me it could be piss drinking, as you put on my contract. But I will never agree to that.

G: Don't be so sure.

E: I´ll text you once I'm back home.

G: I can't wait.
