Obeying the rules makes Erica horny

"I love obeying rules and laws!" My sister admits, red with embarrassment.

"What?" I reply, disconcerted.

"It feels good to follow the rules," She continues, lowering her face. "Maybe that is why I choose law as my career. I always obeyed the rules everywhere, whether laws, school rules, our parents, traffic rules, or work rules. I always obey them."

"With no shortcuts?" I ask her, starting groping her tits and pinching her nipples.

"No...brother, Ouch..." She replies, trying not to be interrupted by me playing with her breasts. " Never! That is wrong. The rules exist for a reason; some people have already decided what is right."

"Yeah, all those people who make the rules are men." I agree with my sister, "Some men better than you already made that decision for you. A woman shouldn't question men's rules."

"I agree; women are not people. We don't make the rules," she agrees, "but I didn't know that before you captured me because I was a feminist back then."

"Even so, you preferred to obey the rules blindly," I said, continuing to play idly with her tits while listening.

"Yes, Ouch...!" She moans without stopping to explain. "It is easier to follow the rules. If I follow the rules, I do not need to head-noise my decisions."

"Have you turned the word head-noises into a verb?" I respond, amazed by her self-objectification. "But anyway, that helps you not to think, right?"

"Yes, ....ahhh...brother. If others have already decided the rules, I do not need to make decisions with my head noises."

"But you ran away from our parent's home."

"Yes, but I did it only after turning 18 with a college scholarship because I was no longer bound to Dad's custody at that age. It is legal," she replies, trying to defend herself.

"Sure, but now you are bound to me," I agree with her, groping and squeezing her tits with more strength.

"Of course...ouch...you captured me. I am bound to your rules."

"So, you feel the same about my rules," I ask her.

"It is even better....ahhh... with your prevented rules..."

She pauses for a moment, unable to continue. Her face is red with embarrassment. She looks down, incapable of continue looking at me. I gently gran her face with my hand, making her raise her head to maintain eye contact. I wait a few seconds, letting her give me this answer.

"It makes me wet!" My sister finally admits. "All the sexual rules you **** me to follow make me so horny. Nowing that I have no control over my body and everything I do is your decision. It feels...ahhh...liberating. That's why I want to obey your rules to the letter."

"Good girl," I say, caressing her face with my hand.

She smiles without saying a word. My sister has such a lovely face.

I need to slap her. I have become used nowadays to slapping and spanking my girls. I won't damage my objects, but they can endure some pain. And not in vain they need male discipline.

And I did. I smack my sister's face right in the cheek.

"Why did you do that?" She asks me, confused.

"Is that a complaint?" I ask her back, slapping her other cheek.

"No! Complaining is feminism, but..." I interrupt her slapping her tits. "Ahh... Have I done something bad... ahhh... brother?" She asks me, more interested in her behavior than my slaps.

"No, Sis, you are a good girl," I reply without stopping slapping her.

"I don't understand, brother."

"I only slap you because it feels good. Your tits will be more adorable after doing this."

"So you are doing this..." She says, being interrupted by another slap on her face, "For fun?"

"I have the right to enjoy your body whenever I want," I tell her, returning to her tits.

"Of course...ahhh... brother...My body...your rules..."

"Remember what true love is?"

"Yes...brother... is when a man makes a ...woman...submit...without giving her...any choice."

"And male discipline is how men make women submit. Which means.."

"Yes, ahh! You hit me because you love me...." She completes my phrase.

"You also should thank me, sister. Is another rule."

"Thank you, brother! Thank you! Thank you!"

"This is as healthy for you as your regular doses of humiliation and degradation."

"You are right, brother. Thank you!"

I continue slapping her tits, hearing my sister's cute voice thanking me for every slap. After some more slaps, I move, grabbing her from behind, and with one hand, I keep abusing her tits while making the other reach her crotch.

"You know what comes next?" I ask her.

"Yes! Ahh! You can do it. It is... yours."

And now I start slapping her cunt. She initially tries to contract herself, but I grab her to keep her standing while continue abusing her cunt.

"Thank you, brother, for keeping me in my place," She appreciates my ****, recovering her breath once I stopped slapping her.

I glimpse for a few seconds the beauty of my sister with red marks from my hand on her tits, cunt, and face. Then I grab her leash and guide her to the couch.

"Can I watch porn about this?" She asks me, following me.

"Of course, there is so much porn about girls slapped. I will send you. Even some of them cunts cry due to the ****." I laugh.

"That is...even hotter. I want to see those bitches cry."

I laugh at her answer. My sister is so corrupted that she does not pity other women. No matter how much they are degraded to make porn. I have created a porn addict. I like it!

I sit on the couch and make my sister sit at my side. She remains with her arms behind her back as I command her. She has received her dose of pain, now is time to massage her to alleviate her body.

"I have something for you," I tell her, starting to massage her boobs.

"A gift?"

"Sort of. Haven't you lost something used in your work?"

"I don't remember anything important that I had lost recently."

"Well, it is something trivial, but it could be inconvenient to lose it. It doesn't stop your work, anyway."

"Wait! Yes...Last week. Why? It was you?"

"Guilty. And I have made some improvements."
