Yes. Finally.

You sit down on your bed in the nude and slide your fingers between your legs. You moan out and quickly cover your mouth, doing your best to conceal your noises. From the teasing, you're ready to cum. You forgo any further teasing and plunge them deep into your pussy. You find your favourite place and begin to stroke against it at a rapid pace. Your other hand moves down from your mouth to grip your breast, and then your nipple as you twist it eagerly.

Your breathing speeds up and you can't help but at least softly moan with delight. More, and more, and more...

You fling your head back and audibly moan, but your embarrassment is overshadowed by the great delight filling your body. You lay back on your bed and pant for awhile before getting up to slip on a normal pair of panties, sweatpants, and a loose shirt.

You wobble your legs outside your door, and your sister is standing almost directly outside of it. Your eyes widen.

"I was getting worried you were sick or something. I heard some strange noises." She grins wickedly.

You curse her out. You blame her for everything that happened today--every embarrassment. She just laughs, and hard.

"Wow! That prank worked like a charm!"

Prank?!

She pushes you gently and continues to laugh. "How'd it feel, huh? In front of everyone?"

You look absolutely livid towards her and back into your bedroom, slamming the door behind you. After awhile you go to bed and fall asleep.
