Your wish appears to already be a game your parents play

I went downstairs to the breakfast table and watched my mother in the kitchen. She bent over as my dad entered the room. He was naked.

He grabbed her, pulled up her dress, and jammed into her. She screamed with pain.

"I'll fuck my boy how and when I want," he said. My mom shivered as he bit into her neck and whispered my name.

"Oh daddy," my mom said, "I know how much you love this game." Obviously, somehow, sometime they had played this game before.

"But this time," he said, "the real son is watching."

My mom looked where he pointed, and saw me. With a mix of horror and embarrassment, she tried to remove herself from dad. But he held her onto him.

"Bad boy," he said.

Mom looked to me for help.
