Erica is needy at the door

The campus has changed a lot. But it is for the best. On this new campus, the professor can make the misogyny class I always wanted to attempt. And my sister will assist as one of my tools.

Now is the time to focus on my sister. I need to continue corrupting her.

I returned home, ate with my girls, and relaxed until my sister finished her work.

She sent me a message half an hour minutes ago telling me she is already on her way. I assume this time she will take more time to arrive thanks to my new rules. I required her to masturbate on her card and my elevator so she is wet and needy the moment I open the door, and also, she must undress and put on her leash. All of that before even knocking at the door.

Look, she is here.

I let my maid Binita open the door for me while I remain behind, looking at the scene where my sister couldn't see me.

Binita opens the door, and I assume she has found my naked sister, but she reacts as if this is the most normal thing in the world.

"Hi, mistress," Binita greet her. "Master is waiting for you."

I hear my sister replying to her back, but I can't understand what she says.

"Sorry, Mistress," Binita replies. "I can't grab your leash. Master's orders."

Binita remains a few seconds in the door, checking something outside, and returns, closing the door and holding my sister's clothes. My sister is still naked at the door.

"Master," Binita tells me when passing by my side. "I did as you told me. Mistress Erica is waiting outside."

"Good girl," I praise her while petting her head. "Put away her clothes. I'll take care of her."

I stop at the door and start looking peephole before opening it. Behind the door is my sister, totally naked and having her leash attached to her cunt. She also keeps her arms behind her back, making it impossible to hold the handle of her leash, so she grabs it with her teeth.

She is nervous and embarrassed due to being naked outside my door. Looking at the other entries and the elevator in case someone else arrived.

I enjoy for a moment her humiliation before finally opening the door. I can see on her face she is mad, but she doesn't try to complain. At this point, she knows it would be useless.

"Hi, sis. How are you?" I greet her while picking her leash from her mouth.

"Hi, brother. I thought I was about to die due to the embarrassment but good."

"And horny, I assume."

"Oh, yeah, " she tells me with a lascivious smile. "But you should check for yourself."

"Remember what you agreed today, right?"

"Of course, brother. I have agreed not to cum. I am telling you I am horny because it is true. I can't lie to you. It doesn't mean I should cum."

"Good," I reply as I start pulling her leash. "Come inside."

But unexpectedly, my sister doesn't move. She remains still at the door. Even with me pulling the leash attached to her cunt, she doesn't move.

"What are you doing? Go Inside!" I command her while pulling more from the leash.

"Sorry... Brother...I can't," She replies while enduring the pain from the leash pulling from her clit.

"What?" I ask, perplexed. "Are you disobeying me?"

"No... Brother... I can't enter...because I am obeying... your rules."

"Explain," I tell her as I stop pulling the leash.

"You told me I can't enter your house unless my wetness is checked."

"Yeah, I can see you are horny."

"But you haven't checked it."

"I can tell you to ignore that rule now."

"But that would be wrong. A woman should obey men's rules."

At this point, I think my sister has some fixation on rules. She always follows them strictly. I thought it was for her lawyer mindset, but maybe there is something more.

I move close to her and put my hands on her cunt. She is wet, indeed, and starts moaning once I start rubbing it.

"Very wet, indeed. Is it thanks to your vibrator?" I ask her, but I already know the answer.

"No...Brother...It stopped...when I finished my work...It was...you?"

Of course, it was me. I stopped the vibrator at the hour she should have left work. That gives her a few minutes of relaxation to reduce her libido, so she must work once arriving here to restore it, all but herself.

"Guilty. You should be wet for yourself before coming home. So, did you edge instead?"

"Yes..ahh.. brother... I masturbated a little in my car when I parked in front of the building, then I continued on the elevator, and I masturbated again in front of your door, already naked."

"Did you reach the edge?"

"Yes... brother... I did it and then called... at your door."

"Good girl," I praise her as I approach her face.

I keep in front of her, letting her sense my respiration in her mouth. I continue rubbing her cunt while both are breathing over the other. She is so horny and needy...

And at this moment, she kiss me.

It is not a caste kiss between siblings. I kiss her back, and both our tongues start to play. Her tongue tries to invade my mouth, and I let her win this time. I allow her to enjoy all the corners until I begin to do the same with hers.

I pull the leash, making her cunt close to my crotch. She replies by rubbing her cunt on my legs, so I stop touching her with my hand to let her do it herself.

"You want to cum, Sister?" I ask her while continue kissing her.

"Yes...brother..."She replies one word at a time with the kissing in between." I...am..so...horny...I need..it."

"But do you deserve to cum?"

"No...Brother...I don't... I promised...you...I wouldn't...cum"

"So, I shouldn't let you do it?"

"Yes...brother...Please... I want it...But...I must...kept...promise.my promise."

"Don't cum, Sis," I tell her the order she wants to heat while breaking the kiss.

Then, once my sister has complied with all the rules I set for her, I pull her again from the leash, and she finally follows me inside the home.

I close the door behind her but stop her at the entrance. She looks so great naked and leashes with her hands behind her back. Still, she holds her head high no matter the degradation, but I always like that on her. It is like she is proud of the degradation.

"You look so good like that. Keep your hands there until I tell you. You won't need your hands today."

"Sure, brother."

"I also have a question. Why do you seem so obsessed with rules? The APP made you obey my commands no matter what, but no other girl has your fixation with the rules."

"I am just obeying you. If you give me orders, the APP forces me to obey you. Your rules are also orders."

"I think there is more. Answer my question with full sincerity. Tell me what you really feel about it."
