"Spread your ass for Mommy"

Zoe doesn't react much to the suggestion. You can tell she's thinking. Behind her big pretty eyes, there's a sense of shock and uncertainty, but surely if her mom is telling her this is all okay, and if her body is telling her this is okay, it must be.

At least that's what you imagine is going on in her brain. You have no idea what might actually be going on in the brain of a pretty 18-year old, whose mother just told her to present her asshole.

"Let's go little missy. If you want your ass fucked, you've got to get it lubed up first. So turn and spread." Caroline's tone is stern. You wonder if it's the same tone she uses when she tells her daughter to clean her room.

It works. Zoe nods, flips around in front of her mother, raises her cute rump, reaches her hands around and spreads it.

It's an amazing sight to see. Zoey's body is petite, unblemished, and perfect. And her asshole is no different. You reach down between Caroline's legs and give her swollen clit a rub.

"Oh.... fuck..." Caroline says in a moan. You're not sure if she's reacting to you, or how delighted she is to be staring at her daughter's star-shaped anus.

Whatever it is, she's feeling bold enough, slutty enough to spit on it. Again, then again. Caroline's thick spit drips down and runs through Zoe's ass crack. Her face is inches from Zoe's flesh. But she hesitates, you think, for just one moment, to make physical contact.

Maybe there's no escaping the fact that it's her daughter before her, the girl she birthed, nursed, raised, shaped, every day for the past 18 years. And if she actually makes contact with her, then there's no going back. There's no return from that decision.

Or maybe she's just taking in Zoe's beautiful ass one more time before she leans in and slicks her tongue through it, which she does with determination and excitement. After all, she passed the point of no return, quite some time ago.

Zoe's body shudders. The sensation of an eager tongue lapping up at her asshole must be strange enough, before considering whose tongue it is.

She moans. "Mmmm.... mmmm...." her teeth chatter. Then "Mmmmm... oh Mom...." and suddenly she notices something. "Mom.... my..... mirror?"

Caroline laughs with her face buried in Zoe's ass. She pulls back. "Do you like it? Don't worry dear. Before tonight is over, everything in this room will be covered with cum. Including you. Do you like the sound of that?"

"I.... yes." Zoe seems to be realizing that at this point she needs to let go of what's happening. To accept that this is her life now, and it's going to bring her immense pleasure.

"Do you know why you like the sound of that?" Caroline asks, her tongue still dabbing at Zoe's flesh. But Zoe doesn't have an answer. So Caroline gives her one. "Because, like your Mom, you're nothing but a...."

"Slut!" Zoe jumps on her cue. And she does so with thrill and joy in her voice. You can't really see it, but you sense that for the first time since she walked into this room, Zoe has a big smile painted across her face.

And your cock can't take much more of this. It needs to explode now or it needs to be shoved into Zoe's ass quickly. You decide that Caroline's run the table long enough. She's done a very good job, and will be rewarded. But it's time that the person really in charge here, takes charge.
