You make Cathy a good sister
“What am I doing here anyway?” you ask yourself as you lie in bed but can’t fall asleep. In the room next to you is a hot chic who can’t resist you and you’re actually thinking about fapping? You moron!
Of course Cathy is crying after her first day of enslavement, but you don’t really care by now. Her head jumps off her pillow as you enter her room unannounced. You almost fall on your face at the amount of trash and the untidy state of the room, but you are fixated with laser-like precision on the bulges of her body that her long loose pants and oversized shirt can’t hide.
“Ethan?” her voice croaks, and she sniffles heavily.
“Who else?” you ask coldly, closing the door behind you, “On your knees.” This time it’s the surprise that makes her hesitate but that doesn’t interest you or her brain that’s now entirely at your service and her shock makes her writhe painfully, just as she always will from now on. You press your lips together as she clumsily falls off her bed. “Show me your tits. Make them jiggle like last time.” With tear-soaked cheeks, your big stepsister obeys you and presents her breasts to you while she can’t look you in the eye.
Quickly you have crossed the room and crouched down next to her. Your hands immediately find their target and grip tightly, squeezing the soft flesh of her udders, hurting her but you don’t care.
“Why are you doing this?” she sniffles again, then painfully draws in air as you take her nipples and lift her heavy breasts up by them. Then you drop her sacks and repeat the process a few times, watching them jiggle.
“Are you stupid or what?” you ask without much emotion in your voice, and as you focus all your attention on your sister’s magnificent tits, Cathy is shocked as her brain let’s her tell you what the rules are.
“Yes,” she sobs.
“Yes, what?”
“Yes, I’m stupid.” Her lower lip trembles while you hurt her.
“You are stupid and depend on someone like me to explain the world to you?”
“Yes, I am stupid and depend on my brother to explain the world to me.” You shake your head and sigh slightly annoyed. But you wanted it that way and that’s how you like Cathy, even if she asks a bit too many questions. But you can remedy that.
“Stand up.” Cathy obeys and stands in front of you, trembling, her arms limp at her side, struggling not to shield her breasts from you. Then she gasps as you reach into her waistband and pull her shorts off completely.
“Maybe I’ll manage to teach you a few commands” you murmur as your gaze settles on her dry cunt. “Nothing complicated. Just easy enough for a dumb cunt like you to understand that she has to… mmh… for example, present her cunt when her master looks at her.” You wait a second, then Cathy understands without being shocked. Her whole body trembles as her fingers slowly wander across her skin down to her crotch, then pulling her fleshy labia apart. “I know you’re too stupid to think of this yourself but you should spread your legs when you present yourself to your master”.
“Yeah… s-sorry bro… Is it okay like that?” Her voice almost breaks but you are rewarded with a deep insight into her innermost.
“Almost. Are you also too stupid to understand that you should be wet for your brother?”
“Y… N…” Her eyes stick to you while your fingers idle over her opening. “I don’t know bro. What should I answer?” You grin and slide a finger inside her. At first the frightened girl flinches away from you, then remembers and holds still, trembling heavily.
“Good girl.” You look up at her as your finger drives into her, widening her roughly. “Degrading yourself is always a good idea given our past. But obeying me is more important, of course. Do you understand?”
“No.” she trembles, “I’m too stupid and scared for that.” Again you sigh. What are you going to do?
“Say you’re sorry you’re not wet for your brother.”
“I’m very sorry I’m not wet for you Ethan” she presses out whimpering. “Can you please tell me what I can do to be wet for you? So I can please you?” You nod appreciatively.
“Touch yourself,” you order, and you’re no longer ashamed of your inexperience. What used to make you afraid to approach Cathy, actually your best help for tips on the subject of girls, is now quite indifferent to you, especially since you are no longer dependent on consent. “For now, it’s okay that you’re too stupid to understand that I mean you no harm,” you say softly, and her eyes betray for a split second that she doesn’t believe you. Then her programming kicks in, she is shocked, sinks to her knees in front of you and nods eagerly. You grab her tightly by the chin, your fingers wet with tears. “I’m your brother, Cathy. Of course I want you to be okay. Do you want that too?”
“Yes,” she sobs eagerly, managing a ridiculous smile. “Yes!”
“Then you’ll always be wet and willing for me from now on.” And Cathy’s hands move quickly and eagerly between her spread thighs and begin to rub her clit.
“Oh yeah,” you say, smiling nastily and standing up. “I was going to answer your question.” Cathy just looks at you dumbly, distracted by your movements as you pull down your shirt, then your pants. “Do you remember what you wanted to know, or are you too stupid?” You see that Cathy knows what she asked, but she hesitates, weighing her options. Finally, you think before opening your fucking mouth. Then she decides on what makes a good sister.
“No Ethan,” she says tonelessly while her mouth is slightly open and her fingers feverishly roam over her pleasure center. She looks at you from below, big wet puppy dog eyes, naked and ugly in a beautiful way. “I’m too stupid and I don’t remember. Can you please help me, brother? I want to please you.” And she smiles adorably.
