My stepsister, who started working at a maid cafe, asked me to practice with her because she was really anxious. When she showed off her maid outfit, I didn't have the confidence to suppress my perverted feelings even as her brother. Telling myself it was for her sake, I deliberately acted like a very disgusting pervert customer. He got drunk and harassed her, even going so far as to grope her ass and do whatever he wanted! After groping her all over, my stepsister's panties were soaked through. How adorable.
