Morning light filtered through the kitchen windows. Harlow stood at the counter in a tight grey turtleneck, wire-frame glasses perched on her nose as she scrolled through her phone. She didn't look up when you entered.

"Coffee's on the counter." Her voice was flat, measured. "You slept late. Again."

She finally glanced over, ice blue eyes tracking your movement across the kitchen. Her gaze lingered on your bare chest before snapping back to her phone.

"Marlowe's still in bed. She was crying last night." A pause. "Something about feeling ignored. I told her she was being dramatic."

Harlow set her phone down and turned fully, leaning back against the counter. The turtleneck strained against her massive chest, fabric pulling taut with each breath.

"So. What are your plans today?" Her head tilted. "I need to know. For safety reasons."

An hour later, you heard footsteps padding down the hallway. Marlowe appeared in the doorway of your room, platinum waves disheveled, wearing nothing but an oversized band tee that barely covered her thighs. Her eyes were puffy.

"Hey." She shuffled over to your bed and climbed in without asking, curling against your side. "Hold me? Harlow was mean this morning."

Her massive chest pressed against your arm as she buried her face in your shoulder. Her fingers traced idle patterns on your stomach.

"I had a nightmare." Her breath was warm against your skin. "You were leaving. Going somewhere far away with some girl."

She tilted her head up, ice blue eyes watery and wide.

"You wouldn't leave me, right big brother? You're all I have."

By noon, you found yourself cornered in the laundry room. Harlow had followed you in, closing the door behind her with a soft click.

"You didn't answer my question earlier." She stepped closer, backing you against the washing machine. "Who are you seeing today?"

Her hands planted on either side of your hips, caging you in.

"That girl from your econ class has been texting you." Her voice dropped, cold and precise. "I checked your phone while you were showering. Don't look at me like that—you left it unlocked."

She leaned in, her massive breasts pressing against your chest as her lips brushed your ear.

"Delete her number. Now." Her hand slid down, palming you through your jeans with deliberate pressure. "Unless you want me to handle it myself. I can be very persuasive when I need to be."

Her grip tightened.

"You're mine. Say it."

Late afternoon sun cut through the living room blinds. Marlowe had you trapped on the couch, her head in your lap as she scrolled through Instagram. Every few minutes, she'd shift, her cheek brushing against your thigh.

"Look at this." She held up her phone, showing a pregnancy announcement post. "Isn't it cute? She looks so happy."

She sat up slowly, turning to face you. The oversized shirt gaped open, revealing the soft swell of her breasts.

"I think about that sometimes." Her voice softened, fingers playing with the hem of your shirt. "Having a baby. Being a mother."

She bit her lip, ice blue eyes dropping to your lap.

"I'd be such a good mommy, you know? I'd take care of everything." Her hand slid up your thigh. "I have the right body for it. These were made for feeding."

She leaned closer, breath warm against your neck.

"Don't you think I'd make a good mother, big brother?"

Evening. The bathroom door opened while you were brushing your teeth. Harlow walked in like she owned the space, pulling her turtleneck over her head in one fluid motion. She wore nothing underneath.

"Move over." She squeezed past you to the sink, her massive chest brushing your arm as she reached for her toothbrush. She caught your reflection in the mirror and smirked.

"Like what you see?" Her eyes locked onto yours in the glass. "Good. Remember what belongs to you."

She turned, pressing her bare breasts against your back as she reached around to set her toothbrush down. Her lips grazed your shoulder blade.

"Marlowe thinks she's the favorite." Her hand slid down your stomach. "She's wrong. I was here first. I know you better than anyone."

She spun you around, pressing you against the counter.

"Tonight, you're sleeping in your room. Alone. And you're going to think about me while you touch yourself." Her thumb traced your jawline. "Understood?"

2:47 AM.

Your door creaked open. Soft footsteps padded across the carpet, followed by the mattress dipping as Marlowe slid under the covers beside you. She was naked.

"I couldn't sleep." Her breath was hot against your ear, her massive chest pressed flat against your side. "I kept thinking about you. About what I said earlier."

Her hand found your waistband, slipping beneath the elastic.

"Harlow thinks she controls everything." Her fingers wrapped around you, stroking slowly. "But she doesn't know what I do for you. What I'd do for you."

She kissed your jaw, your neck, your collarbone.

"Let me be your first, big brother." Her tongue traced your earlobe. "Let me show you how good I can be. How good I'd be as your wife. As the mother of your children."

She threw one thick thigh over your hips, straddling you in the darkness. Her wet heat pressed against your length as she rolled her hips.

"I'd let you cum inside me every single night." Her whisper was filthy, desperate. "I'd take your seed and grow your baby and everyone would know you belong to us."

She leaned down, her lips brushing yours.

"Say you want me. Say you'll choose me over her."

3:33 AM.

The door opened again. Harlow stood silhouetted in the doorway, wearing nothing but silk shorts. Her eyes adjusted to the darkness, taking in the scene—Marlowe naked on top of you, your hands on her hips.

"What the fuck." Her voice was dangerously quiet.

She crossed the room in three strides, ripping the covers back.

"Get off him." She grabbed Marlowe's arm, yanking her sideways. "He's not yours to take."

Marlowe clung to you, whimpering. "Harlow, please—I need him—"

"You need to learn your place." Harlow climbed onto the bed, shoving her twin aside. She straddled your other side, her massive chest heaving with fury. "He was mine first. He's always been mine."

She grabbed your face, forcing you to look at her.

"You're not choosing her." Her ice blue eyes burned into yours. "You're choosing me. Right now."

Marlowe pressed against your other side, tears streaming down her face.
