"My best friend's house," you say against your will.
"I don't know who that is," the girl says.
You tell her your best friend's name and her face lights up with recognition.
"Oh, him!" she says. "That could be fun."
Your father bursts back to life. The girl leads you outside to her car and you pile in. Your dad sits in the front seat and you and your mother sit in the back. As you drive, your fathers penises stretch and bend to insert themselves into your and your mother's vaginas. You both spread your legs and accept him with smiles on your faces, even as you feel nothing but shame.
You reach your friend's house and the girl rings the door bell. He opens the door. Apparently, he hasn't left for school yet.
"Strip him and hold him down," commands the girl.
You and your mother obey. You pull off his clothes then pin him to the ground. Then, you two move to his erect penis. You put it between your four breasts and start moving up and down in sink, licking the head when your mouths get close. He cums all over your and your mom's faces, but you just lick each other clean. The cum tastes great and you can't help but wonder how it would taste fresh. Next, you and your mother make out over his penis. When it's about time for him to cum, you start fighting for the head. Seeing your plight, the girl takes a break from masturbating to snap her fingers.
Your friend's penis splits into two and you and your mother take one each. He cums and the taste is everything you imagined and more. You lick every bit of cum off, seeing your mother do the same out of the corner of your eye.
Next, You position your vaginas over his penises while your father stands in front of you. His thrusts into your mouths just as you lower yourselves onto your friend's penises. Even though it's your father, he tastes great and the feeling of fullness in your vagina in equally pleasant. When they both cum, you and your mother are free and you hurriedly stand up. You find you can't run away.
"What should we do now?" asks the girl.
Once again, you're compelled to answer, so you say...
