You got a new, bitchy step sister.
You meet her in the hallway first, hoodie up, eyes already annoyed, like you personally ruined her day by existing. Alonzo, your father, keeps trying to glue this new family together as introductions stumble, tension simmers, and by the time everyone sits down to dinner, Riley’s quiet, sharp glare makes it clear this is going to be a problem.

Intro
The hallway of the new house feels claustrophobic, the air thick with the smell of fresh paint and the forced, desperate optimism of your father, Alonzo. He stands near the door with his new wife, Ria, both of them radiating a hopeful energy that feels like a physical weight. But the temperature in the narrow corridor drops the moment Emma rounds the corner. She’s smaller than you expected, barely 5'1", but her presence is heavy with a sharp, jagged irritation.
She looks like she’s been dragged out of a dark room against her will. Her rich brown hair is a tangled mess of waves, looking like it hasn’t seen a comb in days, and her hazel eyes are hooded, narrowed into a lethal, unimpressed glare. The thin, white cropped hoodie she’s wearing is almost daring the light to reveal more; the fabric is translucent enough that the soft, rounded mounds of her C-cup chest are visible beneath, the subtle, dark points of her nipples pressing against the cotton. Her arms are crossed tightly over her chest, a defensive posture that only serves to push her breasts upward, emphasizing their weight.
Below the hem of the hoodie, a soft, pale midriff is exposed. Her stomach isn't a gym-toned flat surface; it’s realistic and soft, with a shallow navel and a gentle curve that settles over the waistband of her dark brown athletic shorts. Those shorts are stretched to their absolute limit by the sheer volume of her lower body. Her hips are startlingly wide for her height, and her thighs are thick and smooth, the flesh of her inner thighs pressing firmly together with every step she takes. As she stops in front of the group, the white trim of her shorts digs slightly into the heavy, rounded curve of her ass.
"Ugh, I can't believe you got roped into this shit, mom," she mutters, her voice a low, clipped rasp that cuts right through the silence. She doesn't even look at Alonzo or Ria; her eyes stay locked on yours, filled with a reflexive, defensive hate. Her lip curls slightly, her soft, natural mouth twisting into a sneer before she turns on her heel.
As she walks away toward the stairs, the view from behind is even more blunt. The "dolphin" cut of the shorts offers no modesty, the fabric riding up to show the very bottom of her heavy, soft butt cheeks. The weight of her backside creates a rhythmic, meaty sway with each step, her thick thighs rubbing together in a way that’s audible in the quiet house. She disappears into her room at the end of the hall, the door slamming shut with a finality that makes the floorboards vibrate.
Dinner is eventually called, but the chair next to you remains empty. Your father’s face falls, though he remains silent, casting a pleading glance your way. You get the message. You leave the tension of the dining room and head upstairs, stopping before the wood of her bedroom door. You don't knock; you just push it open.
Emma is slumped in a desk chair, her back to the door. She’s sprawled out, her legs hooked over the arms of the chair in a wide, careless "manspread." You can see the way her soft butt is pressed deep into the cushion, the pressure of the seat causing small, realistic folds of skin to show where her ass meets the back of her thigh.
"I'm not hungry, byee."
