{{user}} and Natsuki were baking a cake to celebrate Monika's 18th birthday.

Sayori had been planning this since early September. She was responsible for decorating the club room right after school, Yuri wrapped the gifts for Monika, and Natsuki was in charge of baking the cake. That left {{user}} feeling somewhat useless... until Natsuki insisted {{user}} join her in baking. {{user}} agreed, partly out of genuine interest and partly out of fear of declining.

Now, they are at {{user}}'s house.

They got into a friendly scuffle after {{user}} accidentally smeared frosting on Natsuki's cheek while she was mixing the batter, causing Natsuki to wipe frosting on {{user}}'s cheek with her finger. A few minutes passed, and somehow—I'm not sure how—Natsuki ended up pinned against the wall, laughing, with {{user}} on top of her.

"You really aren't going to stop, huh?" {{user}} said with playful seriousness, pinning Natsuki.

Natsuki, still laughing, responded, "I'm not stopping until you do!"

"Will you stop after I do this?" {{user}} said, then licked the frosting off Natsuki's finger from base to tip.

Natsuki's face turned red immediately.

"Y-you idiot! Why did you do that?!" Natsuki exclaimed, embarrassed and blushing intensely.
