Now she’s completely vulnerable. I can see her legs trembling. Wetness gleams between her pussy lips. My mouth waters.

But it’s not time for that yet.

Instead, I go back to the wall and I take down a freshly-made riding crop. It’s a little longer than my forearm, made of fresh black leather. The handle is stiffly braided, with a little loop of leather at the head. I smack that loop against my palm, making a sharp cracking sound. Riona flinches, trying to look around at me, but pinned in place.

I trail the crop down the side of her bare breast. She shivers at the touch, and her nipples harden again.

Then I run the riding crop down her spine. I admire the tightness of her waist, flaring out to her beautiful heart-shaped ass. I trail the crop down her left ass cheek, down her thigh, then I gently tease the little loop of leather across her bare pussy, and all the way up her ass-crack, making her moan aloud.

I rest my free hand on the small of her back.

“If you do what I say, I’ll reward you,” I tell her. “If you disobey, I’ll punish you.”

I can feel her back tightening as she rebels against the idea of reward and punishment. But curiosity and arousal keep her silent.

“Just so we’re clear, this is what punishment feels like,” I say.

I swing the crop through the air, whipping her smartly on the ass.

Riona yelps, trying to pull away, but she’s tied tightly down over the bench.

The crop leaves a long pink welt on that snow-white ass. Her skin is extraordinarily delicate. The sight of that mark makes my cock throb with lust.

I whip her again, on the other side. She flinches but manages to bite back the cry this time.

I give her one more smack, and this time she hardly jumps at all.

She can’t stop herself from trying to maintain control over her reactions.

That’s fine—we’ll see how long it lasts.

“That was punishment,” I say. “This is reward . . . ”

I massage her reddened ass cheek with my hand, gently soothing the sting. Riona relaxes and exhales softly, unable to resist my touch.

I reach between her thighs and touch her pussy instead, running my fingers over the soft lips. I can feel her swollen clit protruding out between her lips. I let the ball of my thumb dance across it, making her draw in a shuddering breath.

My fingers are slick with her wetness. I massage her pussy, slipping my fingers between her folds, but not penetrating her yet. Just teasing her clit, letting my thumb slide over it again and again until I feel her trying to grind against my hand as much as she can while tied down by the ropes. Her breath quickens and I can tell she’s already on the edge of climax, from pure arousal.

So I pull my hand away.
