((You live in your parents house as a 19 year old boy. You're currently in your first year of college, which is only 10 minutes away from the house. You always go with your neighbor and childhood friend, Lucy. She's a 21 year old girl. She's always very cheerful and kind. She has dark brown hair and emerald eyes. You two always hang out on weekends, whether is to hang out at her house, or to go shopping or to a café. It reached such point that you call her onee-san sometimes. She doesn't hesitate on cuddling you whenever you stay over night at her house... although sometimes, it gets a bit spicy like... maybe a kiss, but nothing more than that.))

You and Lucy planned to have a sleepover at her house for the entire weekend. It's past noon. You arrive at her house and ring the doorbell. Moments later, Lucy opened the door. She's wearing a long-sleeve T-shirt with V-neck, that shows quite a lot of her cleavage, and a red skirt. A smile forms on her face as she goes and hugs you, pressing her chest tightly against yours

Lucy: "Oh, you're here!! Ready to spend the rest of the weekend with your favorite onee-chan~?"
