You own Cathy
“Are you sure?” Cathy winces when she sees his look. “I mean, you’re right, of course… But you’re fucking me so well and I thought…”
“I have to do something for school sis,” Ethan grumbles, not quite satisfied himself but still dominant. “I can’t fuck you all the time and I already told you to keep up appearances.”
“Yeah okay… but…” She begins to tremble slightly. “You’re not going to punish me after this, are you?” She sounds like a frightened little girl. “Please, Ethan? I do want to obey you. I… I’m scared.” Ethan stands up. He is not much taller than her but still towers over her like a dark god. His hand goes to her cheek and caresses her skin.
“I’m not a monster Cathy,” he says reassuringly and the girl exhales in relief. Then he gives her a firm but friendly pat on the cheek. “Now do as I say you stupid piece of fuck meat.”
“Yes, brother.”
“Hey babe.” Brad hugs his girlfriend and Cathy does the same. She stiffens, expecting to be shocked, but she is just doing her duty for her brother and meets her boyfriend at his house. “What’s wrong?”
“Nothing” she lies, something she will do frequently today.
Her boyfriend lives with his buddies in an untidy, beer-smelling apartment near the university where he feels like a king but Cathy feels uncomfortable. Now it’s even worse, she doesn’t really remember what their relationship was like before her little brother. The two watch TV, football, like they always do, and Cathy snuggles up to him like they always do.
“Where are your friends?” she asks, wincing. Not because she’s been shocked, but because she’s brought up a subject that will lead to something she no longer knows how to handle.
“Today we’re alone” he grins, pulling his girlfriend closer. “We haven’t seen each other in so long.” Normally Cathy would let herself be taken out to an expensive dinner before spreading her legs for her boyfriend, but he’s noticed quite correctly that she hasn’t had much time for him in the last week. And so she just smiles wryly as he runs his tongue over her neck.
“Fuck you look so hot.” And he’s right. Cathy has really made an effort, washed, made up and styled her hair to please her boyfriend, that is to please Ethan to please her boyfriend. It’s all so confusing for the formally confident girl, but she tries not to let on as she flops down on the sofa next to her boyfriend.
Soon she feels his hands on her body and she knows that she has to return his advances, she does it and feels the lust rising in her. Her boyfriend is well-built, muscular, strong and confident. But that doesn’t make Cathy feel the throbbing in her labia. With him it’s always a pleasurable battle for dominance, not this time though, Cathy has forgotten how to be dominant in bed, but her boyfriend enjoys the false superiority she radiates. While he kisses her neck and his hands start to wander, Cathy breathes faster. But it’s not her boyfriend who makes her heart beat lustfully. She spreads her legs for him, feeling his hand under her pants, his fingers on her panties, then on her clit.
“Are you okay?” he asks again but doesn’t stop kissing her.
“Yeah… keep going…” Usually, Cathy has always set the pace but not today and her boyfriend quickly finds that she is literally overflowing. His movements become more demanding and soon the room is filled with moans and the wet squelching of her cunt. “Shit you are really horny” her boyfriend laughs and starts to undress. Cathy does the same with a blank look, but smiles at him when he looks at her.
Yes, she is wet. But the truth is that she is not spreading her legs for her boyfriend. Not for her boyfriend she moans as he penetrates her. And it’s not for her boyfriend that she wraps her legs around him.
It’s all for Ethan. It’s all for her little brother.
As her body disappears beneath her boyfriend’s and her arms close around his back, her legs around his hips, Cathy can think. The sex is good but nothing in this world, nothing in her universe even comes close to the sensationally powerful feelings she has with Ethan. Cathy cringes as she imagines her brother on top of her. Her boyfriend doesn’t recognize the pale welts on her skin, doesn’t recognize the altered gestures and sounds she makes. He is lost in his lust for her.
And while Cathy is being fucked by the only man in her life she allows to fuck her, she can only think about her brother. Her boyfriend is stronger, better looking, makes more money, is often nicer, used to be more determined, was more confident, is no more intelligent, has never been so determined to achieve a goal, is too stupid to realize who Cathy really belongs to, will never understand that the feelings Ethan evokes in her are too powerful for him.
As she feels his cock inside her, Cathy realizes the truth. The pain is the most brutal feeling she can feel. But right after that comes the relief when she submits to Ethan, the endorphins when she does something he likes. Nothing in her life is as addictive as beating the pain through submission. Nothing is as important as that. And if Cathy has to change her behavior, even her thinking, to do it, so be it. She’s addicted to doing the right things. And somehow she’s addicted to the pain, too. Because without the pain, she wouldn’t be able to experience the divine feeling of defeating the pain. She is strong she realizes. But only for her brother.
Her boyfriend comes inside her, kisses her and she kisses him back, wild and loving at the same time. But in her mind there is only Ethan. He has won, is the only person who matters. And Cathy is happy about it.
