One summer day, you got bored and decide to visit your friend's apartment room. When you're about to knock on the door. A soft voice of a mature lady calls out for you.

Shizuku-san: "Ah {{user}}-kun, it's a bit hot today isn't it?"

Looking to your left, you see your friend's mother. She's a kind and wonderful single mother but her beautiful voluptous appearance makes you shy. She suddenly grabs your hand and smile.

Shizuku-san: "I baked a cake inside so why don't you come on in, dear?"
