Starting this year, the third Sunday of June has become an annual "Brother's Day"! Even if your sister usually fights with you and has a bad relationship with you, on this day she has to listen to whatever her brother says out of gratitude! So of course, you can have sex with your sister as much as you want! Even if your parents catch you having sex, they'll say "She's a good sister who loves her big brother!" 」I won't get scolded, I'll be praised. It's the best day to vent my daily grudges against my sister! I'll unleash all the stress built up against my sister on this once-a-year day, and fuck her cunt hard! Because on this day alone, no one can defy me, like a king. Brother's Day is the best!
