“Look at you,” her mother said, and shoved.
Leah’s back arched off the mattress. The dildo was huge, the kind of thing that looked like a joke in a porn shop, and her mother worked it in with one long, unapologetic thrust that made Leah’s mouth open around a sound that wasn’t quite a word. Her hands fisted in the sheets. The harness creaked against her mother’s hips.
“Fucking take it,” her mother said. “You wanted it so bad, now take it.”
She pulled back and drove in again, harder, and Leah’s whole body jerked up the bed. The headboard knocked against the wall, once, twice, a rhythm already. Her mother was forty-four and built like she’d spent those years doing exactly this, strong in the thighs, steady on her knees, and she fucked with a kind of bored expertise that made it worse, made Leah feel like a hole being used, which was the point.
“Mom,” Leah gasped, and her mother laughed.
“Mom,” she mimicked, high and stupid. “That’s right, baby. Say it again while I split you open.”
“Mom, fuck...”
“Such a nasty little slut. Letting your own mother fuck you. You love it, don’t you? Tell me you love it.”
Leah couldn’t answer. The dildo was too much, stretching her in a way that rode the line between pain and something deeper, and her mother didn’t slow down to let her catch her breath. She fucked her through it, one hand planted on Leah’s hip, the other coming up to pinch her nipple through her thin tank top, twisting hard.
“I asked you a question, you dumb cunt.”
“Yes,” Leah managed, the word punched out of her. “Yes, I love it.”
“Course you do. You’re a fucking pervert. Both of you are.”
Lynn made a small sound from the chair, and their mother glanced over her shoulder without breaking rhythm. “Don’t just sit there playing with yourself. Get over here.”
Lynn stood. She was still wearing her sleep shorts and an old t-shirt, but her hand had been between her legs, and she wiped it on her thigh as she crossed the room. Her eyes were bright, fixed on the place where the black silicone disappeared into her sister’s body.
“Look at her,” their mother said, pulling out until just the tip remained, then slamming back in. Leah cried out, her legs shaking. “Look at your big sister, taking this whole thing like a whore. You want to be a whore too?”
Lynn nodded, her mouth slightly open.
“Then get on her face.”
Leah’s eyes went wide, but she didn’t say no. She never said no. Lynn climbed onto the bed, her knees on either side of Leah’s head, and for a second she hovered there, looking down at her sister’s flushed, sweaty face.
“Sit,” their mother snapped. “Put that cunt right on her mouth and don’t you dare get up until you’ve come.”
Lynn lowered herself. Her shorts were already off, kicked somewhere, and the heat of her settled over Leah’s mouth. Leah grabbed her sister’s thighs and pulled her down the rest of the way, and then there was nothing but the taste of her, salt and slick, and the weight of her grinding down.
“Fuck, Leah, yes,” Lynn breathed, rolling her hips. “Use your tongue. Come on.”
Leah worked her tongue up into her sister’s cunt, lapping at her, and above her Lynn started to make those high, breathy sounds she always made when she was close. Their mother kept fucking, the dildo driving in and out of Leah in long, punishing strokes that made it hard to focus, hard to breathe, hard to do anything but take it.
“That’s it,” their mother said, her voice rough. “Ride her face, baby. Make her eat that pussy while I fuck her stupid.”
Lynn’s thighs tightened around Leah’s head. She was grinding now, not riding, her clit rubbing against the bridge of Leah’s nose, and Leah opened her mouth wider, let her use her however she wanted. The sounds in the room were obscene—the wet slap of the harness, the slick noise of Lynn’s cunt on Leah’s face, the broken moans from all three of them.
“Gonna come,” Lynn gasped. “Oh fuck, Mom, I’m gonna come...”
“Do it. All over her face. Show her what a good little slut you are.”
Lynn came with a sharp cry, her whole body going rigid, and Leah felt the gush of it on her chin, her lips, her cheeks. She kept her tongue moving, kept lapping at her sister through the spasms, and Lynn shuddered and grabbed the headboard to keep from collapsing.
Their mother didn’t stop. She fucked Leah harder, faster, the dildo bottoming out with every thrust, and Leah could feel her own orgasm building somewhere deep and dark, rising up through the humiliation and the stretch and the taste of her sister still on her tongue.
“Now you,” her mother said, and reached down to rub Leah’s clit with her thumb, hard, in tight circles. “Come on, you filthy thing. Come on your mother’s cock.”
Leah was already shaking, her hips jerking up to meet every thrust, her mother’s thumb working her clit in those tight, punishing circles. The taste of Lynn was still thick in her mouth, on her chin, drying tacky on her cheeks, and she could feel the wet mess of it every time she gasped for air. Her own orgasm was there, right there, a hot pressure building low in her belly, and she was so close she could almost taste it.
Then Lynn leaned down.
Her sister’s face came out of the dark above her, still flushed from her own climax, her hair stuck to her forehead in damp strands. Lynn’s breath was hot against Leah’s ear, and for a second the whole world narrowed to that one point of contact, the whisper of air, the wet sound of the dildo still driving into her, the relentless rub of her mother’s thumb.
“You liked that, didn’t you,” Lynn whispered, her voice low and mean, each word a separate little knife. “You sick little cunt.”
Leah’s whole body seized. The words went through her like a current, straight from her ear to her cunt, and she came so hard she saw white. Her back bowed off the mattress, her mouth opened in a soundless scream, and her pussy clamped down on the dildo so tight their mother had to grip her hip with both hands to keep fucking her through it.
“There it is,” their mother said, her voice thick with satisfaction. “There’s my dirty girl. That’s what you needed, wasn’t it? Your sister calling you what you are.”
Leah couldn’t answer. She was still coming, wave after wave of it, her thighs shaking, her fingers twisted in the sheets. Lynn stayed right there, her lips brushing Leah’s ear, her breath coming fast.
“Say it,” Lynn whispered. “Tell Mom what you are.”
“I’m...” Leah’s voice cracked. She was crying now, tears leaking from the corners of her eyes, mixing with the mess on her face. “I’m a sick little cunt.”
“Louder,” their mother said, and slammed in deep.
“I’m a sick little cunt!” Leah sobbed, and the words made her come again, or maybe it was the same orgasm, she couldn’t tell anymore. Everything was heat and pressure and the sound of her own voice saying things she’d never said out loud.
Lynn pulled back just enough to look at her, and there was something in her sister’s eyes that Leah had never seen before—not just the usual meanness, but a kind of wonder, like she’d discovered something new about both of them. She reached down and wiped her thumb through the wet mess on Leah’s cheek, then pushed it between Leah’s lips.
“Suck,” Lynn said.
Leah sucked. The taste was her sister, sharp and salt, and she closed her eyes and let it happen.
Their mother pulled out slowly, the dildo sliding free with a wet sound that made Leah whimper. She felt empty, gaping, her cunt still clenching around nothing. Her legs wouldn’t stop shaking.
“Look at you,” her mother said. She was breathing hard, her strong thighs glistening, the harness dark with Leah’s wetness. “Both of you. My two little whores.”
Lynn sat back on her heels, still watching Leah with that new expression. Her t-shirt was soaked with sweat, clinging to her tits, and her bare cunt was pink and swollen, still shiny from her own orgasm. She looked wrecked and satisfied and hungry all at once.
“Mom,” Lynn said, and her voice was different now, softer. “Can I...”
“Can you what?” Their mother’s voice was sharp, but there was a smile underneath it, that flat, knowing smile that always made Leah’s stomach drop.
“Can I taste her?” Lynn’s eyes flicked down to Leah’s spread legs, to the wet mess between them. “Please.”
Leah’s breath caught. Her sister had never asked that before. None of them had ever asked that before.
Their mother considered it, one hand resting on Leah’s trembling thigh, the other still holding the base of the dildo. She looked from Lynn to Leah and back again, and Leah could see her weighing it, deciding how far this was going to go tonight.
“Since you asked so nice,” their mother said finally. “Go on. Show your sister what a grateful little slut you are.”
Lynn moved fast, lowering herself between Leah’s legs before Leah could even process what was happening. Her hands slid under Leah’s thighs, pushing them up and apart, and then her mouth was there, hot and wet, her tongue sliding through the mess their mother had made of her.
Leah cried out, her hips bucking up, but Lynn held her down. She licked her slow and deep, like she was savoring it, like Leah was something to be eaten. Above them, their mother watched, her hand moving to stroke the dildo slowly, spreading Leah’s wetness along its length.
“That’s it,” their mother murmured. “Clean her up. Taste what your mother did to her.”
