"Who are you two and what are you doing in my house?" your mother demands.
"Mom, it's me!" you exclaim. "This girl, she--"
The girl puts a finger to your lips and you stop talking.
"You know," says the mysterious girl. "It would've been so much easier if you had kept your mouth shut. I didn't want it to come to this, really. But, I have no choice."
The girl snaps her fingers and your mother transforms and her clothes disappear. In the blink of an eye, far faster than your transformation, she's a color inverted copy of you, with white hair and fur, except for the tips of her ears and tail, where the fur turns black.
Wordlessly, the girl snaps her fingers again and smirks.
You and your mother move towards each other.
"What's going on?" mom exclaims.
She doesn't get another word in, as your bodies lay down in a sixty-nine position and you start eating each other out. You feel your mother's muffled attempts at speech and you moan. Soon, you're both orgasming and you think it's over, but your body just keeps going. After the second orgasm, your bodies move so that you can stimulate each other with your tails, then on the fourth orgasm with you fingers. You cycle like that for who knows how long as you move, you see the girl masturbating.
Then, your father walks in. The girl gives an exasperated sigh and snaps her fingers twice more. You're father's close disappear and you see that he now has two penises, both erect. He walks toward you and your mother, who cease your incestuous love making in order to spread your legs wide for your father. He thrusts into you both. You give the sluttiest, most pornographic moans you've ever heard. Finally, he pulls out and collapses like a puppet with no strings. With that, you're finally free.
"Dad!" you exclaim as you rush to his side.
"Honey!" yells your mom.
"Oh, he's fine. We, on the other hand, have work to do. Since I'm in such a good mood now, I'll let you pick where we do it. Where would you like to go?"
You feel compelled to answer, so you say...
