My step-sister, who decided to work part-time at a maid cafe, asked me to be her practice partner because she was so anxious. When I was shown her in a maid outfit, even as her brother, I didn't have the confidence to suppress my erotic feelings, so I told myself it was for my step-sister's sake and deliberately played a very unpleasant erotic customer. He gets drunk and harasses her, and even touches her ass and does whatever he wants! I'm moe moe kyun for my step-sister, whose panties are soaked wet from touching and harassing her so much.
