KHIP-013 The charming buttocks of the older cousin

I decided to take care of my female student niece for a while. In the past, he often said things like, 'I will marry you, Onii-chan!' Even now, he still hasn’t eaten the food I prepared, lying lazily on the sofa and engrossed in playing games on his smartphone. …Hey, you can see my pants. I don’t know if you’re defensive or if you don’t see me as a man, but I will teach you what happens if you show me that cute butt!
