The Stepfather’s Rules

Marcus hadn’t planned on becoming obsessed with his stepdaughters. When he married Kim six months ago, he’d been focused on her—her submissive nature, the way she melted when he took control in bed, her eagerness to please. She’d quit her job as a dental hygienist two weeks after the wedding (“I want to take care of you, baby, I want to be yours completely”), and Marcus had settled into a comfortable routine of dominant sex with a willing wife.

But the house had other plans.

June was eighteen, a college freshman who still lived at home, all long limbs and volleyball-toned thighs. Katie was sixteen, a junior in high school, softer than her sister, with an innocent face that made her developing body seem almost obscene. And neither of them seemed to understand what they did to him.

It started with the outfits. June in those spandex volleyball shorts that rode up her ass when she bent to load the dishwasher, the fabric thin enough that Marcus could see the outline of her panties underneath. Katie in oversized t-shirts that clearly hid no bra, her nipples hard against the cotton, and sometimes—God, sometimes—nothing below but a pair of cotton panties when she shuffled to the bathroom in the morning.

Kim noticed him noticing. He’d catch her watching him watch June stretch for a cereal bowl, her eyes dropping to the tent in his sweatpants, then back to her daughter’s unaware body. She never said anything. But that night, when he fucked her, she was wetter than usual.

“Do you like looking at her?” Kim had whispered, her legs wrapped around his waist. “Do you like her tight little ass in those shorts?”

Marcus had pinned her wrists. “Is that what you want? You want me to look at your daughter?”

Kim came instantly, clenching around him, her eyes rolling back. “I want you to have everything,” she gasped. “Everything that makes you hard.”

That was when Marcus understood. Kim didn’t just submit to him—she submitted to his desires, whatever they were. And if his desires included her daughters...

He started slowly. A family meeting in week three, casual, almost reasonable.

“New house rules,” he said, sitting in his armchair while Kim knelt at his feet—a position she’d taken naturally since the honeymoon. June and Katie sat on the couch, June with her arms crossed, Katie with wide, trusting eyes. “We’re a family now. Families don’t have secrets, and they don’t hide from each other. No closed doors in this house. Bedrooms, bathrooms—if you’re here, the door stays open.”

“That’s insane,” June said. “I’m eighteen. I deserve privacy.”

Marcus looked at her evenly. “You deserve what I give you. Your mother supports you. I support your mother. This is my house now too.”

Kim said nothing. Her breathing was audible, shallow and quick.

Katie just nodded, her gaze flicking to Marcus’s crotch, then away, her cheeks flushing.

June stormed out. But she left her door open that night. Not wide—just cracked. But open.

The dress code came next. Marcus started “helping” with laundry, folding Kim’s panties with deliberate care while the girls were in the room.

“Your mother works hard to keep this house,” he said to June, holding up a pair of her worn cotton panties—white, with a damp spot at the gusset that made June’s face turn crimson. “The least you can do is look presentable. From now on, I approve outfits before you leave your room. And around the house—no more sloppy sweats. Shorts must be approved. If I can see panty lines, you’re not trying hard enough. Thongs or seamless only.”

“You’re disgusting,” June hissed, snatching the panties from his hand.

“Am I?” Marcus looked at Kim. “You don’t think I’m disgusting, do you, Kim?”

Kim’s hands were shaking. “Do what he says, baby,” she whispered to June. “He’s ... he’s right. We should look nice for him.”

June’s eyes narrowed, but Marcus saw something else there—confusion, maybe. Or the first hint of that shameful arousal he was learning to recognize.

That night, Marcus woke at 2 AM to find Kim’s side of the bed empty. He found her in Katie’s room, standing over her sleeping daughter’s bed. Katie was on her back, one leg thrown out from under the covers, wearing only a tank top and panties.

“Kim?” Marcus whispered from the doorway.

Kim turned, and her face was transfigured—guilty, terrified, and wildly aroused. She held up one finger, wet and glistening in the moonlight.

“I was just...” she breathed. “I wanted to know if she was ... if she gets wet like I do. For you.”

Marcus stepped into the room, closing the door softly behind him. “Show me.”

Kim’s hand trembled as she lifted her nightgown, exposing her breasts. She rubbed her wet finger across her nipple, coating it in her daughter’s juices. Then the other nipple. She was shaking, her breath coming in short gasps.

“Taste her,” Marcus commanded, his cock hardening in his boxers. “Taste your daughter on your own tit.”

Kim lifted her breast, sucking her nipple into her mouth, moaning around the flesh. Her eyes rolled back. When she released it, the nipple was hard and shiny.

“Marcus,” she whispered. “Wouldn’t you like to taste her? Wouldn’t you like to know if her cunt is as sweet as mine? She’s only sixteen. So tight. So innocent. I could get her ready for you. I could bring you her panties, her wetness...”

Marcus grabbed her, spinning her around, bending her over Katie’s desk. He shoved her nightgown up and drove into her in one thrust, covering her mouth with his hand to muffle her scream.

“You’re a filthy fucking mother,” he growled in her ear, fucking her hard, watching Katie sleep not five feet away. “You’re going to get me your daughters. You’re going to serve them up to me.”

“Yes,” Kim gasped against his palm. “Yes, I’ll get them wet for you. I’ll bring you their juice. I’ll make them ready. Please, Marcus, please...”

She came silently, her body convulsing, her cunt milking him. He pulled out and came on her ass, watching it drip down her thighs while she trembled.

Later, in their bed, Kim curled against him. “I want to watch you take them,” she whispered. “I want to see you break them. I want to taste them on your cock.”

Marcus came inside her, groaning against her breast. “You’re perfect,” he gasped. “You’re the perfect wife.”

June broke on a Sunday night.

Marcus had been building it for weeks—the looks, the casual touches, the way he made her describe her outfits, her underwear, her grooming. She’d started wearing the thongs. She’d started leaving her door open wider. But she hadn’t given in.

Until Marcus found her in the laundry room, holding a pair of Katie’s panties. They were soaked. Not just damp—soaked through, the crotch stiff with dried arousal, the fabric dark with wetness.

“Your sister’s been busy,” Marcus said from the doorway.

June jumped, dropping the panties. They landed on the tile with a soft slap. “I was just—”

“Curious?” Marcus stepped into the small room, closing the door behind him. Not locked—he never locked doors—but closed enough to give them the illusion of privacy. “You want to know what she tastes like? Your little sister? You want to know why she’s so wet all the time?”

June backed against the washing machine, her face crimson. “No. That’s sick.”

Marcus picked up the panties, held them to his nose, inhaled deeply. Sweet. Young. Musky. “She’s been dreaming about me. Haven’t you noticed her door open wider lately? Her shirts getting smaller?”

“She’s sixteen,” June whispered, but her eyes were fixed on the panties in Marcus’s hand. “She doesn’t know what she’s doing.”

“She knows exactly what she’s doing.” Marcus stepped closer, crowding June against the machine. “And so do you. You’ve been wearing those thongs I picked out. You’ve been leaving your door open. You’ve been asking for this.”

June’s breath was coming faster. “I haven’t—”

“Don’t lie to me.” Marcus grabbed her wrist, pulled her hand between her legs. “Feel that. You’re soaked. Just like your sister. Just like your mother.”

June gasped as her fingers pressed against her own damp cotton. She could feel the heat, the slickness, the betrayal of her own body. “I can’t help it,” she whispered, tears forming in her eyes. “I try to stop but I can’t—”

“Because you don’t want to stop.” Marcus released her wrist, stepped back. “Family meeting. Living room. Five minutes. You, Katie, your mother. Now.”
