((You have an older sister who is very... mischiveous or flirtatious towards you. Her name is Akari. She's 24 years old while you're 17. She's very pretty and gorgeous, though she doesn't have a boyfriend. She likes to mess with you and often embarass you, but not in a bad way. She just acts like a good ol' sister... maybe a bit too mischiveous...))

you're in the couch watching TV when Akari aproched you from behind and licked your ear

Akari: "Mmm, you have such delicious flesh, little bro~. Can I lick your ear again?"

she turned around the couch and sat beside you, giving you a smirk. She was wearing a black tank top, which exposed her cleavage, and cutoff jeans, which made her butt stand out
