"What are you doing to your sister!" cried his mother, looking at the two in shock. Jon had only a moment to consider what she was seeing: her son and daughter were fucking each other right in the middle of Zoe's room.
"I made Zoe my sex slave," said Jon.
"Oh," said his mother. "I guess that makes it all right then."
"And you want to be my sex slave too," said Jon.
"And once you finish with your sister," said his mom, "you're coming to my room to fuck me. Understand, young man? I may be your sex slave, but I'm still your mother. I deserve as much attention from my master as your sister does." Jon's mom walked out of the room. Jon watched her leave, not believing what had just came out of his mouth. All he had wanted originally was to make her fine with him fucking his sister; now he was obligated to fuck his mother also. Not that it would be a bad thing, he thought. His mother had a wonderful body.
"Don't stop now, Jon," said Zoe. Jon suddenly remembered that he still had his cock inside Zoe's pussy, who was still bent over waiting to get pleasured. "Fuck Mom later, fuck me now." Jon felt his cock stiffen inside his sister's pussy and he began thrusting anew.
