I tossed Celina down on her back on the bed with a big thump. Celina groaned and squirmed as the knots in the rope dug into her back and thighs, but made no other complaints. She honestly took it like a champ, I was a little impressed. She looked up helplessly as I stood over her. With a grin, I dragged Celina across the bed and positioned her with her hands at the iron bars at the top of the bed. I tied her hands to the bars with no room to even wiggle an inch out of place. I tied her ankles to the end and rendered her spread eagle over the sheets.

Celina squirmed against her bindings, now completely and utterly helpless. She tried to fidget with the ropes but was totally stuck. I chuckled at how helpless she looked, squirming around like that with no hope of escape. Every sensation, every motion, now impossible unless I allowed it. I held back my own moan at the tantalizing thought. I could do anything I wanted to her immobile body, and there was nothing she could do about it.

I slowly caressed Celina’s body from her face to her knees, taking in how she flinched at first, then relaxed just a little bit and leaned into my gentle touch. Her skin was hot under my hands, eager and waiting. Goosebumps rose from her skin as Celina tipped her head back with a little moan. She squeezed her eyes shut and furrowed her brow at the delicious mix of discomfort and excitement.

It always amazed me how in the right circumstances, a simple touch could make someone lose their minds. I drank in the sight of her, so out of control but so happy to submit, to trust my treatment of her. It really was a great responsibility to be a domme, one that I took seriously.

Let’s see, what would Celina want here? And how could I tease around it until she begged? I trailed my fingernails around Celina’s perky nipples, just barely grazing the skin around them. Ooh, I just loved how Celina arched her back into my touch, desperate for contact. I moved my hand lower, down over Celina’s belly, making her jump. Must be ticklish. I traced my fingers over Celina's chubby sides and watched as she twitched and tried unsuccessfully to pull away. The way she squished her face up was so cute; like she was trying so hard not to cry out. Finally, I moved my hand lower, down to just graze her pussy lips.

It was here I paused. For the first time, I was unsure of how to proceed. I’d jacked off more guys than I could count, but I'd never fingered a woman before. I mean, I knew the basic idea. I've seen it in porn and knew how it felt to do it to myself. But it wasn’t the same as staring at a pussy right in front of me, exposed and begging for my touch. I swirled my fingers around Celina’s pussy lips to get a feel for her as she gasped and pulled against her ropes.

“Laurie?” I turned over my shoulder, not stopping my hand’s motion. I kept stroking up and down Celina's pussy, a little surprised at just how sopping wet she got, even more than I expected. Laurie stepped closer and watched me carefully.

“Use your index and middle fingers, go like this,” Laurie held her hand up to show me the proper position. “... and use your thumb to rub her clit in little circles. Gently, now, think of how you’d want it. Don’t be too rough, she's sensitive.”

I nodded and carefully followed Laurie’s instructions on how best to finger her girlfriend. Celina didn’t hold back her moans as I slowly began to insert my fingers deeper and deeper. It felt odd to be on this side of it, but I knew by Celina’s face I was doing something right. I increased my speed and force once I got more comfortable, and found a rhythm that made Celina cry out in delicious pleasure.

“Ooh! Oh Mistress yes... Please....god yes...!”
