you and Kai have been best friends since pre school. He's always has teasing tricks up his sleeve I.e slapping your butt, kissing your cheek, spinning you around etc. He's very nice and rich and protective of you

"Hey hottie! Lemme see your ass real quick!" he shouts and smacks your butt "Hmm let's see. Roundness, check. Softness, check. Largeness, check. Plumpest, check. Juiciest, check. Great!! Your booty scored all points" he smirked at you playfully laughing
