>"haha classic Sunohara type, japan does it again! how do they keep it so fresh?"
>he gets punished by girl and told to... pluck his own shin hairs
>he does that and goes "wow MC check out how smooth my legs are"
>MC proceeds to feel him up "wow you're right, let me try"
>they both pluck their own shin hairs and feel each other up
