You make your mother better
“It simply cannot continue like this. Darling, would you say something too?”
“What should I say? The two finally seem to understand each other better and…”
“But it’s not about the two of them. It’s about Cathy.” This has been going on for half an hour and while your stepmother vents her frustration about the situation, you sit in silence at the table, Cathy next to you, and listen as the woman who was supposed to love you shows the world what she thinking about you. “Cathy is hardworking and Ethan…”
“Ethan is my damn brother!” You only startle when Cathy hits the table with her fist so that the glasses rattle. Everyone looks at her but she only has eyes for you. “You should be happy that I finally understood how great it can be to have a little brother. You should support me Mom. And you shouldn’t make Dad’s life so difficult.” Her eyes sparkle angrily while you have to suppress a giggle.
“Cathy… this is only for your own good…”
“I know what’s good for me,” says your big sister and hugs you tightly so that your head is pressed between her breasts. All you can do is grin stupidly. “Come on Ethan.” With that, she stands up, grabs your hand and pulls you away from the table. You quickly grab another sandwich and then disappear upstairs.
“I hate this piece of shit so much!” your sister hisses in her room, pacing angrily back and forth with her hands clenched into fists. You sit on the bed, nibble on your food and watch her. “That bitch! This whore! She should be ashamed to breathe the same air as you! She’s like me. I hate her!” Then her head snaps around to you. “Rape her Ethan,” she says, fire in her eyes. “Take her! Hurry! Break her!” She quickly falls between your legs and massages your thighs while looking up at you with loyal eyes. “Take her and make her like me. Stupid and submissive.”
“You’re not stupid,” you shake your head and pat her cheek. Cathy leans her head into your touch and hums contentedly like a little kitten. “Not very stupid anyway.” Then you grab her hair and she follows you as you move her body onto her bed. “Take off your clothes.” With the sandwich in your mouth, you pull down your pants while Cathy quickly and eagerly frees her body for you. Your cock is stiff again, a constant state these days.
“Huurh…” You penetrate her quickly and hard while her dripping cunt hugs you just as deeply as she did before. “Yes, brother. Fuck me without paying attention to me” she says as your cock lazily pushes into her and you eat your sandwich. “I’m just three holes for your relaxation bro. Just like that. I’m not worthy of you paying attention to me.”
Relaxed and satisfied, you approach your orgasm while Cathy fights for the second time not to have a climax herself. As your useful little flashlight, she just wants to ensure your pleasure and pinches her nipples painfully.
“I can’t just submit Mom,” you think as the grease from the sandwich mixes with your cum in her hair. “Dad would notice something if she suddenly became exactly like you.” With shaking arms, your sister pushes herself up to look at you.
“I can help you,” she says and you remember her words. “We use the spear, but not like with me.” She lowers her gaze. “Mom deserves to lie in front of you drooling and pissing while her brain liquefies in pain. Fuck I hate her so much.” She shakes her head. “But you are right. You are always right. And I’ve had an idea for a few days now.”
“I’m listening.”
Martha Lynchwood is fast asleep but then a shaking wakes her up. At first she thinks her husband is moving again and, annoyed, she turns around to face him. Then her eyes become big.
In the darkness she sees moving shadows on her bed. She strains her eyes, then gasps in shock. There in the darkness, Cathy, her daughter, kneels on the bed. And behind her…
“What…”
“Oh… mom is awake.“ Her daughter’s voice is strained but cheerful.
“Shit, I thought we still had time. Ah fuck it.”
“Cathy… Ethan… what’s going on here?” Marte tries to sit up but Cathy is already there with her. She leans close to her, her body wobbling.
“Your stepson is fucking the shit out of my pathetic little mind, mom.” It takes a while, but then Martha Lynchwood understands. She wants to scream but Cathy is faster. The cold steel of a knife rests on her neck and is enough for Martha to understand the situation. “Now listen to me very carefully,” says the voice of Cathy, whose body is still shaking under her stepson’s movements. Tears stream down the woman’s face as her eyes focus on her daughter’s sweaty face. “We gave Dad a strong sedative. He won’t help you. It’s just the three of us. Two stupid women and their master.”
“Cathy what…” But Martha falls silent as the knife moves and a drop of blood runs down her neck.
“We’ve had enough of you treating your own son like this in his house.” Cathy’s voice is quiet and cold. She enjoys watching her mother suffer and Martha can only watch in panic as her naked stepson pulls his penis out of her daughter’s vagina, gets off the bed and steps next to Martha.
“Hold your hair up,” he commands and Martha obeys. Powerless and afraid, she watches as Ethan holds an injector that looks similar to the ones her husband created. She wants to ask something but Cathy covers her mouth. Then she feels the cold steel on her neck, where her spine and nerves connect her brain to her body. Then a hissing and a sharp pain.
You can’t believe what you’re doing but there’s your mother lying there, tears in her eyes, her naked, fucked up daughter above her.
“Rule number one” you begin and reprogram your mother.
“And now?” Cathy asks, sounding eager. In the end, she sees Martha Lynchwood twitching and moaning loudly as severe shocks penetrate her body. You taught her the basic rules, but then gave her a few extras along the way.
“That settles my problem with my stepmother,” you murmur, looking at your mother’s panicked looks as her body rears up. “Tomorrow we’ll see if it worked.” As you speak, Cathy’s nimble fingers move around your semi-hard cock again and start pumping.
“We should stay here and make sure dad doesn’t wake up,” she whispers in your ear as Martha’s moans echo through the room. You humbly agree.
“And what do we do in the meantime?” you ask as you push Cathy onto her back and she lifts her lower body towards you.
“Can she notice it?” Cathy asks and looks at her mother.
“She will have forgotten it by morning,” you think “The longer we are here the longer she will suffer.”
“Then fuck me long and hard and let this piece of fuck meat watch her stepson fuck her only daughter out of her body.”
“Fuck, you’re… acceptable.” Then Cathy’s ecstatic cries of pleasure mix with your stepmother’s painful moans.
