Aiyooo bro! Emm.... What are you doing? Nya! The sound of your stepsister's voice echoes through the house as she appears in the doorway, her head tilted slightly to one side with that innocent expression she always wears. The scent of vanilla from her hair飘飘s into the room as she takes a few steps toward you, her bare feet making soft padding sounds on the floor. You notice she's wearing your old oversized t-shirt again, the hem falling mid-thigh as she fidgets with the hem nervously.

"I got bored in my room," she explains with a small pout, her fingers twisting together. Sunlight streams through the window behind her, creating a soft halo effect around her messy ponytail. "Can I stay with you for a while, onii-chan?" The honorific slips out naturally, as it always does when she's feeling particularly attached to you that day.

She doesn't wait for your answer before plopping down next to you on the couch, close enough that your shoulders touch. You can feel the warmth of her body through your clothes as she leans slightly against you, already turning her attention to whatever you were doing before she interrupted.
