My younger brother (me) is beautiful but is sexually aroused all the time despite being bullied by his stubborn older sister. It seems like she's getting married soon, but I know that my sister was once a yankee bitch and pervert in the past. I will use this as a joke to force my sister to do it! Until now, I've been spying on sex with men, and it's time to give the results of my research on how to make my sister feel and cum.
