A test to keep it.. (new author)

Ninja girl raises her beautiful eyes to meet yours. The cruel lift to her grin sends trembles through your body. Your heart is pounding, and your trapped pearl is wiggling despite the massive orgasm you just had. You want to ask her if she's going to let you keep your clit or not, but you can't work you mouth to form the words.

Slowly, oh so slowly, ninja girl slides the cric-clamp free of your clit. But your heartbeat doesn't slow. The wicked look in her eyes fills you with fear and lust, equally, confusingly. She leans down and get something from her sports bag. Your brow knots. Is that a spool of thread? Ninja girl dexterously ties a perfect noose into the free end of the thread. You are impressed, if very confused by the display.

"You've been a very bad girl, haven't you?" Ninja girl trails the noose over your belly.

You instinctively deny it, shaking your head no. "No, I haven't!"

"Lying too," Ninja girl tsks at you. "Have you not been exposing yourself while playing with this hungry little clit?" She taps your love button with her finger. "That's two things right there. And let's not talk about, how you were looking for me. Trying to see my face in the crowd every night you went out."

Caught, you just stare at her. Ninja girl grins. "So, if you want not only to cum again tonight, but to even keep your clit, you are going to have to face a test. A challenge if you will."

Though she didn't ask, you nod your head. You don't completely know why, but you say "Yes, I'll take on your test."

"Good girl," Ninja girl leans down to your still wiggling clit. She gives the fleshy pearl a couple of teasing caresses and then with her nimble fingers, slips the thread noose around the base of your nub. Her eyes sparkle as she quickly, and roughly, draws the noose tight. It makes your clit stand taller, a little more swollen. She gives it a teasing kiss and then stands up.

Keeping the thread tight, even giving your clit a tug every so often, she unspools the thread, leading it up over the headboard of your bed. Pulling it back through, she leads it down to your face. Again, with her quick and nimble fingers she ties a largish knot in the thread near the spool. Once satisfied, she snaps the thread free and tosses the spool down beside you.

"You are going to keep this knot in your mouth until I tell you to let it go." She taps your lips with the thread. "I think you know what will happen if you don't?"

You swallow and nod your head. Ninja girl mimes opening her mouth. You follow suit and she places the knot between your teeth. "Now, let's see how good you are, while I sample your pearl some more."
