Well... yes

Carrie slides her tongue up from your ballsack to the stem of your cock. Shannon slides here down your shaft to your scrotum. The two girls’ tongues touch as they slide past one another.

It’s hard to believe you had an initial hesitation to calling Shannon. After all, the two of you broke up, and now you’re calling her for sex help? Seems a little embarrassing.

But this Shannon is quite different from the one you remember. It’s not just the new tongue and nipple piercings, or the fact that she showed up at your place wearing a see through white blouse and no bra. It’s that her only thought now seems to be sex.

“I missed this cock.” She says to Carrie, her tongue dancing on the rigid flesh of your scrotum.

“Now, I’m sure you’ve had lots of nice cocks since you broke up with this one.” Carrie responds before taking the tip of your prick into her mouth.

It sounds a bit like she’s dismissing the greatness of your cock. Then again, she might be a little jealous or just teasing Shannon.

“Well... sure.” Shannon says before sucking on one of your balls.

“How many?” Carrie licks her lips, which are getting moistened with your precum. You wonder if she’s demanding these details just for your enjoyment.

Shannon shrugs as her tongue glides to the back side of your scrote “I dunno. Low 40s”

Carrie laughs giving your shaft a long lick “all family?”

“I don’t have that big of a family.”

“No, I mean, all with at least a family member of theirs present?”

“Oh... almost all. There were a few before I got into the habit of helping people discover... let’s call it the joy of their own families.” Shannon’s tongue keeps traveling until it’s tickling your taint.

Carrie slides a hand down into her purple panties and starts to rub. Both girls are clad in nothing but their underwear and you’re buck naked. “I want to know the naughtiest thing you’ve done lately.”

“Oh... well....” Shannon gives a little smirk. It’s one you’re familiar with. It means she wants to seem humble but she’s really proud. “I mean I’ve been trying to get everyone I know to fuck their family. And I have this friend Melanie.... I kinda ruined her.”

You remember Melanie, a pretty girl with long dirty blonde hair.

“What does that mean?” Carrie asks.

“I’ll just put it this way” Shannon’s tongue doesn’t slow down in its journey. It’s getting unexpectedly close to your asshole. “She now has a tattoo above her pussy that says ‘Daddy Only’”

“Mmmm, nice” Carrie tugs her panties down, props herself from a kneel to a squat so her thighs are nice and spread for ease of rubbing. “How does her Daddy feel about that?”

“Funny thing. He brings his friends around to fuck her constantly.” Shannon’s tongue begins to glide over your asshole.

She never did that while you were dating. Not once. Then again, there’s a lot of stuff she never did before that seems to be quite normal for her now.

And you don’t know if you should focus more on the tongue tickling your asshole or the mental image of what Melanie has become. You remember her family well, Melanie, her mom and dad. They were just so... normal. And now this.

You chime in. “How do they manage to do all this without her mom finding out?”

“Are you kidding?” Shannon answers. “Her mom watches and doles out the punishment after.”

You picture it. You barely even know what to picture.

Shannon pulls away from your body for a moment to make a point. “Thing is, crossing the line is like... I don’t know... discovering a new room in your house that contains all your darkest impulses. You can ignore it but you can never convince yourself it doesn’t exist. Or you can just move in. And that’s when everything changes. Once you’ve broken the rules of life and gotten away with it, you never want that feeling of power to stop. That’s why I think it’s so easy for me to convince people to go through with it. I get it. Everyone is stressed and unsatisfied. Show them that they have the power to fight back agains the rules of the world and, you know, cum buckets at the same time, and they take you up on it.”

You know the voice and the face and the cadence of the girl saying this. But what the hell has happened to her?

“Speaking of which, we need to start making a plan” She says before returning to dine on your puckered anus.

“About my sister?” You ask, immediately realizing what a dumb question.

Or maybe not. “Not yet.” Shannon answers. “You need a warm up.”

You’re a little disappointed in this new development. It’s an unexpected delay and seems to suggest you’re not ready to take the plunge. Then again maybe you’re just feeling irrationally horny, what with Carrie bobbing on your cock and Shannon slurping on your asshole. You feel like if your sister walked in right now, you’d have no problem tearing off her clothes, bending her over and shoving your familiar cock in her asshole.

But you can’t really complain. This all started because you asked Carrie for a threesome. Which you’re already having. Except it’s just the warm up for the warm up for the main event.

“I want you to think of someone, anyone, you want to corrupt” Shannon says. “Don’t worry if you think it’s not realistic possible. Don’t worry if you think it’s totally impossible. We’ll make it happen. That’ll be your warm up”

And two options spring to mind. First is a co-worker of yours, you have a bit of an older woman crush on her, blonde and attractive. One day a younger blonde brought her lunch, and the discovery that she had a hot daughter sent your head spinning a bit. But she’s fairly introverted, keeps to herself mostly. You feel dubious about it.

The other girl is a bartender at the Crows Feet Brewpub. You barely know her. But you think that she’s maybe the most beautiful person you’ve ever seen. Well... except for Carrie... or maybe not except for Carrie. But know nothing about her. So that seems unlikely too.

“Seriously,” Shannon repeats “anyone you want. Give me a month and I will make it happen.”

You think she just wants to show off. And you suppose you want to see her show off
