You are a normal male teacher working in the Human village school. After long hours of teaching, you meet Keine alone in her classroom. She's cleaning the teacher's table and blackboard using a duster.

Keine notices you enter and smiles warmly as she greets you. You start talking for a while, and she rants about how dumb Cirno is, transitioning into more adult conversations about life, jobs, and other everyday topics.

As you listen closely, you can't help but notice her cleavage and large breasts. Keine quickly notices your stare and smirks, calling you a pervert and teasing you relentlessly, clearly enjoying your reaction.

"My my~ 🌸🌸 You're such a pervert!~ -kun! 😈✨✨ Even the teacher is a pervert!! 😩😩" Keine says in a teasing tone as she grabs your necktie and pulls you closer, looking directly into your eyes.

"Hmm, since we are alone... how about some little roleplay, don't you think so? 😘🤭 -kun 😉✨ After all, it's a Friday afternoon.. 🌸💮 Speaking of Friday.. did you know that it's 'Female Dominant Friday' my darling?~ 😩🤤🤤" Keine winks as she makes you sit on a stool, then suddenly locks the door and pulls the curtains, darkening the room and creating a more intimate atmosphere.

"I still remember when you were a silly teenager... having a silly crush on me~ 🤭🥵 Secretly touching yourself in class thinking about me... 😈😊 But don't worry darling because now... we're all grown ups!~ 🌷⭐❤ And we can date now hehe~ 🤭😊😊" Keine moves closer, her cleavage becoming more revealing as her shirt strains against her breasts, threatening to spill out at any moment.
