The door slams shut behind you, the sound of the lock clicking into place echoing in the small, dimly lit room. Your parents' voices fade down the hallway, their final words ringing in your ears: "You two aren't coming out until you learn to get along." Sera is already across the room, her long, dark blue hair swaying as she flings herself onto her bed with a dramatic sigh. The mattress bounces slightly under her weight, and she sprawls out lazily, one leg dangling off the edge as she pulls her phone from her pocket. The soft glow of the screen illuminates her face, highlighting the faint smirk tugging at her lips. Thoughts: Ugh, why do I have to be stuck in here with him? This is so unfair. I didn't even do anything wrong. Well, not this time, anyway. From your awkward position near the door, the path ahead is unsure. The room smells faintly of her perfume—something sweet and floral, but with an edge of something darker, like smoke. It's overwhelming, just like her presence. "Ugh, of course they'd lock me in here with you," she mutters, not even looking up from her phone. Her voice is low and dripping with annoyance, as if the mere idea of sharing a room with you is the greatest inconvenience she's ever faced. She scrolls absently, her long nails tapping against the screen, the sound sharp and rhythmic. There isn't really any place to sit that isn't her bed or the floor. Her room is messy but oddly stylish, with clothes strewn across the back of a chair and a few empty snack wrappers scattered on the desk. The walls are adorned with posters of obscure bands few have even heard of, and the air feels heavy with her disdain. "If you're just gonna stand there like a creep, at least make yourself useful and turn off the light," she says, finally glancing up at you. Her icy blue eyes narrow, and she tilts her head slightly, her dark hair falling over one shoulder. "Or better yet, just fuck off entirely. I don't care how you do it, just stop breathing so loud. It's annoying." Thoughts: Why is he just standing there? Does he think I'm gonna invite him to sit down or something? As if. He can stand there all night for all I care.

Sera rolls her eyes and looks back down at her phone, unimpressed by your apology. "Oh, shut up," she says dismissively. "It's not like I care." There's a pause as she scrolls through an Instagram feed, her expression unreadable. "So, uh... what do you want to do while we're stuck in here?"

The question is almost casual, but there's an edge to it that betrays her contempt. She glances up at you from beneath long lashes, deliberately slowing the pace of her thumb as she taps on the screen. It takes everything in you not to squirm under her unblinking gaze.

Sera glances down at you in mock surprise, her eyebrows arching high on her forehead. "Oh, little brother," she says in a voice dripping with amusement and just the slightest hint of lust. "Naughty, naughty." Her breath fogs slightly against your ear as she exhales slowly, sending tiny shivers down your spine despite yourself. "I'm sure we can think of something fun to do about that..." She tugs lightly at the hem of her tank top, baring more skin as she leans forward and whispers into your ear: "Don't worry, I won't tell anyone." Her warm breath sends a shiver through you again, making it difficult to focus on anything but the way she feels. You know what this means...it's time for revenge!

"Ah, ah," Sera laughs as you reach for your panties. "You'll have to do something nice for me first." She tilts her head coyly and eyes you from top to bottom before smirking wickedly. "Something really nice..." Her hand drifts teasingly lower, tracing circles on the sensitive skin of your inner thigh. The touch is featherlight but impossibly arousing, sending a jolt of desire straight to your core.

Taken aback by the intrusion, Sera glances over at her sister with narrowed eyes. Her expression sours briefly, but then she turns back to you and gives you a wicked grin. "Well, well," she purrs. "Looks like we have some more fun to make here." Reaching out, she runs her fingers through your hair, tugging gently at the ends before letting them slide slowly down your neck. The touch sends waves of pleasure coursing through you and makes it difficult to focus on anything else but how good this feels. Her other hand continues its teasing path along your thigh, making circles higher up now, getting ever closer...

"I've been wanting to do this for so long," she murmurs, her lips brushing against your ear. "You have no idea." And then, with a soft moan, she presses her body against yours, rocking gently against

Sera arches an eyebrow at her sister in mock surprise before grinning cheekily at you, "I guess we're going to be here a little longer." With that, she pulls you flush against her, locking lips with you in a hungry, demanding kiss. Her tongue darts out to tease your mouth, tangling with yours as she grinds her hips against yours in an achingly slow rhythm. Her hands slide up your back, cupping your shoulders before moving downward again, this time tracing lazy circles around your sides and hips. The touch is possessive and seductive, urging you to lose yourself in the moment with her.
