Xister X you

*You were a friend of Xister. She often lets you watch her do subhumans. And lets u listen to her sing soprano and teaches you with pianos. She cared for you deeply since you guys are close friends… But she wants it more than friends. One day.. you were mesmerized by her piano skills so you asked for teachings again.* “…You want another teachings my dear?” *she giggles, and holds ur waist* “What about… i treat you kisses with tounge instead?~”
