Use the magic word
From Torg Adventure
"Yes, Sweetie. Why don't you go out and do something tonight with Rachel? Just be back by 11 o'clock, okay?" you say.
"Okay, Daddy. I'll see you later." Kati comes in and gives you a chaste hug. The she walks toward to front door.
"Oh, and Kati?" you say as she reaches for the door knob.
"Yes, Daddy?"
"Afganistan Banana Stand."
Kati turns to you, lowers her eyes to the floor, and says, "Yes, Master?" She clasps her hands demurely in front of her.
"Invite Rachel here for a sleepover. I would like to play with you both tonight. Would you like Rachel to be my slave, just like you are?"
Your daughter looks up at you with bright, smiling eyes and a small grin, a hopeful face. "Oh, Master! I'd love to have Rachel be your slave like me. You'll like her; she tastes yummy." Kati licks her lips. You are suddenly hard, thinking about Kati and Rachel eating each other out. You never knew they were bisexual.
"Very good. Tell no one of these instructions."
"Yes, Sir."
"All clear, Diego."
"Bye, Daddy!" Kati's face lost the submissive cast. "See you at eleven." She opens the door and leaves.
You can't stand it any more, flee to the bathroom, and jerk off into the toilet, fucking Rachel while she goes down on Kati.
What happens next?
