"...squirt all over me"

The suggestion takes a moment to register. What did your sister just ask you to do? Then again, isn't that why you came here to begin with?

Is it?

You can't think straight. You try to remember what brought you to this moment where your little sister is asking you to do this. You came here for a reason. Then you were surrounded by Meg's sluttiness. Then you were indignant. Why? And you wonder if you can't think straight because your head is too stuffed full of horny desire, and your clit itches like something impossible.

Meg smiles at you. It's a wicked smile. She steps forward and places her hand on your chest. It's not a grope, it's not even touching your breasts. If it were it may feel your piercingly hard nipples. But it just sits there comfortingly on your chest. "I want that taste again. Please. Nothing has ever been as good."

And how can you resist? Even if it's your sister. Isn't that what you came here to do? You keep asking yourself that. You have no answer. Suddenly, nothing makes sense any more.

That's not true. One thing makes sense. Your clit. You know what it wants and you know you want to. And Meg wants to. There's no use not giving in.

Slowly you lift up your skirt, revealing your upper thighs, and then your moist pussy.

"It's beautiful" you hear Meg say. She's seen you naked before. But she's never really looked at you naked. Her eyes staring at your slit, wet for her, is the most arousing and inappropriate thing you've ever seen.

Slowly you reach your hand down and touch yourself. You start to rub.

"Mmmm. Yes" Meg says. "Do that for me." You can see her nipples getting hard beneath her tight dress. You're going to experience what it's like to see Meg sexually excited. Sometimes it feels like you're the only person on the planet who hasn't yet.

You rub. A little faster. Then a little faster. Then a little faster. You can't believe you're still on your feet. Your knees quiver. Your body starts to fill with electricity. Maybe you should sit down, or let your body collapse. Is that what Meg would want?

You look at her for direction. But this must be new for her too. As dirty as she's ever been, she's never done anything this taboo.

You close your eyes and feel them slowly roll back into your head.

"Keep going. Keep going" you hear Meg's voice. It makes no sense hearing your sister's voice encouraging you to masturbate. But suddenly this is your reality.

Keep going, you tell yourself. Rub yourself for Meg. Squirt for Meg. Do it all for Meg.

And your teeth chatter. You start to shake. You're almost there. Keep going. You open your eyes to look at your pretty little sister as you cover her with your juices.

And that's when you notice something very unexpected.
