Good son: Tell him you'll Do anything
From Create Your Own Story
You get closer to him and whisper in his ear, "I'll do anything for my Daddy," as you nibble on his ear. "You trying to say you never looked at my cute little ass?"
You turn around and wiggle your ass at him. "Come on Daddy, come on," you say as you goad him in a sexy, almost girly voice. You hear him say "Fuck it," and he grabs and drags you by the ass over to your bed, pulls your pants down, whips his dick out and sticks it in your tight asshole and begins pumping you hard.
"You really are a slut," he says. "Only for you, Daddy," you reply, which spurs him on, and he holds on to your long black hair as he fucks you harder until he finishes inside your ass. You both lay down on your bed, naked, and cuddle as he kisses your neck, saying "This is our little secret, okay?" as you fall asleep in his arms.
