You twirl the left nipple clamp, sparking off the pain again, just as I was beginning to get used to it.

"This left one is only just on the edge of your nipple. Is that hurting more? I bet it is. Look down, Abby, look at the clamps biting into your skin. It makes you feel the pain even more when you can see them, doesn't it?"

I nod, still keeping my mouth open, not daring to try to speak, even to answer you. I look down, looking at the cold, stainless steel clamps biting hard into my tender skin.

"It hurts, doesn’t it?”

I nod.

“Keep that mouth open, Abby. I'm going to use it in a moment."

You lift your shirt over your head and drop your jeans, then your boxer shorts. No need at home for those sexy leather trousers you wear at the club. It doesn't matter what you wear anyway. You could wear a beautifully cut suit or a bin bag and still be able to dominate me.

I never get tired of seeing you naked. I don't have much time to contemplate it right now though, as you grab my hair again and pull my head back.

"Mouth open wider." Another slap. "I said 'wider.'"

You tease my lips with your cock, circling my mouth like your fingers circled my clit only a few days ago. I want to taste you with the tip of my tongue but you have not said I can and so I hold back.

You push your cock slowly into my mouth, the smooth skin gliding over my tongue. You push it right to the back of my throat and hold it there, as if daring me to gag when I am already being punished for another transgression.

I relax my throat, hoping and praying that I can take you in without choking. You pinch my nose closed with one hand and start to move your cock in and out of my mouth, faster and then faster still. I struggle to breath, having to take in air around your cock while you use my mouth.

You slow down for a moment and release my nose and I gratefully take in a huge breath.

You speed up, pressing again to the back of my throat. A few more thrusts and you pull out of my mouth without coming.

You tug on the weights on both nipple clamps. "Still hurting?"

I nod, my mouth still open as you have not told me to close it.

"Good. Shut your mouth, Abby. I'm done with it, for now."

You reach between my legs and roughly cup my pussy, sliding one finger inside me and then another. “You're dripping wet. What a slut. What a dirty, dirty little girl."

I blush and squirm, utterly humiliated.

You bring your wet fingers to my lips. "Taste yourself, dirty girl. Clean my fingers.”

When I am done, you lift my chin. "Look at me."

I do, my cheeks flaming, and my eyes filled with shame.

"You are my plaything. A toy. You are here to please me and that is all. Tell me."

"I... I am your toy, Sir. Your plaything. Only here to please you."

"That is correct. Do you want to please me, Abby?"

“Yes, Master. So much.”

“Good then.”

Your fingers circle my clit, speeding up. “You want to come, don't you?”

“Yes, Sir. Please, Sir.”

“Ask me nicely, slut.”
