“Don’t—” Riona protests, too late. She’s worried about ruining the borrowed dress.

I grab her by the throat and growl in her ear, “Shut the fuck up. You promised to do what I say.”

I see that fire of rebellion in her green eyes, but it’s swallowed up by lust. She wants this as much as I do, though she hates to admit it. I can feel her pulse fluttering against my palm. I can see those gorgeous bare breasts heaving from her rapid breath.

I grope her breast roughly with my free hand. I squeeze its exquisite softness, and I pull on the nipple, rolling it between my finger and thumb. Riona gasps.

Keeping hold of her throat, I fondle her other breast. I go back and forth between them, pinching and squeezing, until her pale pink nipples are swollen and darker by two shades.

Then I duck my head and take her nipple in my mouth. I flick it gently with my tongue, until I feel her squirm. Then I suck hard. Riona lets out a long moan of relief.

I squeeze her breast with my hand while I suck the nipple, as if I were milking her. I can feel her knees going weak, her arms circling round my neck for support.

I work one breast and then the other. Riona grabs the back of my head and presses my mouth harder against her breast, wanting more and more.

Instead, I straighten up and drag her over to the pommel bench. It’s about waist-height, just wide enough for a saddle.

I bend her over the bench and push her legs apart with my feet. Grabbing a coil of rope off the wall, I tie her hands in front of her, and secure them to the bench. Then I tie her ankles, one at a time, so they stay spread apart.

I can practically hear her heart rate increasing. She squirms against the ropes, scared of being restrained, wanting to resist me. But I know she’s curious, too—curious what will happen if for once in her life she relinquishes all control.

Once I have her firmly tied, I step back to admire the view. She’s bent over the bench, utterly helpless. Her bright red hair hangs down around her face, half blinding her. Her bare breasts are pressed against the wood, her ankles tied about two feet apart.

I walk around behind her and pull up her skirt, so the remains of the dress are bunched around her waist. This reveals her two creamy white ass cheeks, round and full and luscious in the pale golden light.

She’s wearing a lace thong. The only thing covering her now.

I pick up a pair of shears off the workbench, their blade gleaming in the light. I open and close them once so Riona can hear their vicious sound.

Then I place the blade against the tender skin of her hip, slipping it under the waistband of the thong. I cut her panties off in one sharp snap. I do the same on the other side, pulling away the shreds of fabric to bare her smooth pink pussy lips, and the little puckered opening of her ass.
