I kept my finger still, buried inside where she was hot as fire. I cracked my other hand hard on her ass before reaching up to shove her back straight once more. The forearm she used to support herself squealed against the countertop.

“Pay attention to me, Ruby. Not just how you feel.”

She exhaled loudly and made it somehow sound like a promise to do better. It was the sweetest music. Her pussy clenched on my finger, and I rewarded her, drawing it slowly out, only to plunge back in.

She whimpered with enjoyment, but held her position this time.

I returned to my task, lashing my tongue wildly against her asshole, and her fingers clenched hard on her own cheek, as if trying to pull it further open. Allowing me more room. Should I order her to put a knee up on the counter? No. She was shaking too much already. I didn’t want her to lose her balance, especially with what I had planned.

Would she be able to maintain her posture with what I was about to do? My finger was drenched, her pussy soaking. I withdrew slowly, and made sure she was damp enough where my mouth was, preparing her for a new experience.

Her muscles tensed subtly. She seemed to figure out immediately what I intended when I replaced my tongue with the pad of my index finger. I swirled once, half expecting her to stop me. But she didn’t. She sucked in a shuddering breath and stepped her feet wider apart. Inviting me to try.

I began to intrude, one deliberate centimeter at a time, watching for any signal she didn’t want to continue.

“Oh . . .” Her tiny sigh sounded curious. Interested, even.

I pressed further, until the second knuckle was squeezed tight by her muscles. She mewled. It was a soft cry of pleasure, but she might as well have screamed it. Ruby seemed to enjoy the slow, gentle glide of my finger, and I eased it deeper with a rocking movement.

Until I was full-out fucking her with it. Her pants for breath were loud, and she collapsed forward, resting her upper body on the counter.

“I’m going to put my dick here,” I said. “Not right now, but tonight. I’m going to slide it right inside this tight, little ass.” I worked my finger faster, and her hips moved subtly in response, as if trying to find maximum pleasure. “Do you like my finger inside you?”

“Yes,” she whispered.

“Do you want to come?”

It was a sob from her. “Yes.”

I withdrew slowly and eased back from her, using the dark tone she brought out in me. “Then get on your knees.”
