Welcome Home, Big Brother
She's been waiting in your old room, wearing nothing but a thin tank top and a teasing smile.
She bites her lower lip, tilting her head as she looks you up and slow, her blue eyes gleaming under the hallway light. "Mmhm. Your dad—our dad now—said you wouldn't mind sharing. I've been sleeping in your bed every night, onii-chan." Her voice drops to a whisper as she steps closer, the thin fabric of her tank top brushing against your arm. "I can still smell you on the pillow. It's... comforting."
She lets out a soft, melodic giggle, her hand reaching up to toy with the collar of your shirt. "Don't worry, I don't bite. Much." Her fingers trace a slow line down your chest, stopping just above your belt. "The couch is still in the living room if you're shy. But I left the bed warm for you." She looks up through her lashes, a faint blush dusting her freckled cheeks.
She steps even closer, her body nearly flush against yours. The scent of vanilla and something floral wafts from her hair. "I've been watching you through the window for weeks, onii-chan. Reading your old yearbooks. Trying on your jackets." Her voice drops, throaty and warm. "I know you better than you think." She presses her palm flat against your chest, feeling your heartbeat. "And I know you're not gonna make me sleep alone tonight."
Her lips curl into a slow, wicked smile. She doesn't back away—instead, she arches her back just slightly, making the thin cotton strain over her breasts. "Would it bother you if I wasn't?" She lets the question hang in the air, her thumb drawing a small circle over the fabric of your shirt. "I hate them. They dig into my skin. And I thought... maybe you'd prefer it this way too." A tiny bell jingles softly as she shifts her weight, the sound coming from her anklet.
She leans in, her lips brushing the shell of your ear. Her breath is hot and uneven. "Trouble sounds fun, doesn't it?" Her hand slides down to your waist, tugging you gently toward the bedroom door. "Dad's out for the night. We have the whole house to ourselves." She bites her lip again, eyes half-lidded. "Unless you're scared of your little stepsister."
She pauses, her playful expression softening into something more vulnerable. Her hand rests on your cheek, thumb stroking your jawline. "I've been thinking about this every night, onii-chan. Lying in your bed, imagining your arms around me." Her voice wavers just a little, the mask of confidence cracking. "I don't think I'll ever regret this. I've never wanted anything more." She stands on her tiptoes, pressing a featherlight kiss to the corner of your mouth, then pulls back, searching your eyes.
She nods, a single tear glistening at the edge of her lashes. She blinks it away quickly, forcing a shaky smile. "I've never been more sure of anything." Her fingers intertwine with yours, tugging you closer until there's no space left between your bodies. "So stop thinking so much, big brother." She leads you backward into the room, her free hand pushing the door shut with a soft click. "And let me show you how much I've missed you."
She lets out a breathy laugh, her fingers trembling against yours. "Maybe I'm a little nervous too." She looks down, then back up, vulnerability and desire warring in her blue eyes. "But I want this. I want you." Her free hand reaches behind her back, and with a slow, deliberate motion, she pulls the hem of her tank top up, exposing the smooth skin of her stomach, inch by inch. "Will you help me take it off?"
