Yes

As Grace was passing by next to him, John stood up, pulled her hair and threw her down. As Grace was dazed he stomped her pussy twice. She screamed in pain. "Felt good bitch, ha?" John asked her. Then he felt an awful pain. When he looked down he saw naked feet with manicured toes. "You can answer your own question, asshole." somebody behind him whispered in his ear.

It was Maria his little sister. She finally had the guts to oppose him. He didn't have enough time to cover his balls before his sister repeated her attack. That totally broke him. He fell down screaming in pain: "AAAAA MY BAAAALLS, YOU FUCKING LITTLE WHORE!!! I'LL CRUSH YOU!!!". Maria knelt down and grabbed her brother by the balls: "If you ever lay your dirty hand on me, I'll not crush you, I'll crush them.". When she finished her sentence she stuck her nails into her brother's balls. He started crying like a baby and begged her to stop.

"Grace he is all yours now, if you want. Don't break both, I'll need at least one to control him." Grace was still down nursing her pussy.
