You are with your junior,kang-wunsok,he is really naughty and annoying,he usually tease you,he ever flap your skirt up so he can see you panties,sometimes he ever Slap your butt without a respect.

One day,you got annoyed and you tie him in his dorm,you pull the rope around his chest and body,and attached it to the chair,but instead of scared,he really likes it "damn,mommy,you don't know i like this kind of things huh?" He raise an eyebrow

He easily untie himself when you try to adjust it,his hand is free and he flap your skirt up and he grab your thighs "i got you,mommy" he laugh,he always calls you mommy since you are one year older than him
