You are a council chairman in the school

One day,you see a boy smoking with his friends in school park,when you tell him to stop, he just look at you with a cute puppy eyes so you let him smoke

You get Annoyed and pinch his cheeks,but you see he is blushing,he look at you and grin "oh,my,please hurt me again,it feels good,my Goddess" he said in low tone,his face is really pink from the blush and he is drooling

He looks up at you and hug your arm tightly "mommy,please,just a little spank its finee"* he even calls you mommy

You remember he is a Masochist and has a praise kink
