Back to Sarah's car.

Sarah leads me back to her car. She doesn't speak a word but her silence holds more threat than anything else I could imagine. Once we are seated she bitch-slaps me twice on my cheeks. "Stupid whore! Too damned selfish to follow even the slightest order. Well, we gunna have to see that you won't fail me again, bitch!"

A whimper but stay quiet. I know I'm due for a painful lesson.

"Okay, first, I want you to open your blouse and lift your skirt. Next, you'll slide one hand under your ass and push your middle finger into your ass."

I nod and do as ordered. I shudder as my finger is pushed deep into my poor rear.

"You like that, do you, slut?"

"Yes, mistress."

"Aww, you're just one fucking, worthless cock whore, bitch! Aren't you?"

"Yes, mistress. Your bitch is one worthless cock whore."

"Good." Sarah reaches for the glove box. I know she keeps quite some evil instruments there. With wide open eyes I see that she takes two adjustable nipples clamps from it. I know this kind of clamps very well by now. They can cause a lot of hurt. I tense my spine and hold my breath.

"Here we go, ****."

Unceremoniously she attaches the clamps to my swollen nipples. I wince as she tightens the screws that they really hurt.

"Like that, bitch?"

I shake my head. "No, mistress. They're hurting me!"

"Good!"

Without warning Sarah slaps my screwed nipples. I gasp just once as incredible pain shoots through my body. At the same moment, the finger in my ass causes havoc to my senses. Pain and pleasure. My pussy gets moist instantenously. "Awwww!" I clench my teeth not wanting to displease my mistress any more.

SLAP! SLAP!

My heavy tits jiggle and the brutal nipple clamps bite into my flesh. I'm in agony and yet my lust is just building up on momentum. I realise I'm close to coming. But Sarah knows my all too well.

"Fucking bitch!" She stops. "This is turning you on, right?"

"Yes, mistress."

"Bah. You're such a shameless tramp." She turns at me and spits. Right in my face. I sniff, but I dont dare wiping my cheek with my free hand.

"You'll stay like that the whole drive. Your blouse stays open and your finger remains in your hole. Don't even think of covering yourself up. Understood?"

"Yes, mistress."

"We'll see."

Sarah starts the engine and drives the car out of the parking lot. Soon we're in deep traffic down the main road. Sarah's car doesnt have darkened windows... I'm visible to anybody looking at the car. My tits are visible. And so are the evil clamps. Sarah doesn't care.

I'm at her mercy.
