I probably should have resisted her advances. I should have at least tried. This was no place for Rosie. She deserved a lot better than this office for her first time. I knew rationally that I ought to take her home, but my body was way beyond rational.

Her body felt electric under my fingertips. She was wearing the same dress that she’d had on the day before, so getting her out of it was easy; I already knew where the zipper was.

Divesting her of her outer clothing was no challenge, but not falling to my knees when I saw her naked again, was. She truly was the most flawless thing I’d ever seen in my life. I pushed the crap off my desk, not caring where it landed, and laid my suit jacket over it. I wasn’t sure if there was some secret protocol to having sex on a desk, so I was just making things up as I went. Rosie stripped off the rest of her clothes, shivering slightly against the cool, air-conditioned air. I followed suit, adding both our clothing to the nest we were building atop my desk. The throw blanket I brought once when the heater went out was added to the pile.

Rosie happily hopped up onto the desk and I followed her. I reached for her, greedy now to touch every inch of her naked body. She let out a little satisfied sigh when she felt my weight.

“Are you sure you want to do this here?” I asked her. She nodded, kissing me back and wearing a determined, sexy smile.

My fingers went to work between her thighs, seeking and finding heat and slick wetness. She wasn’t as tight as she’d been the night before, perhaps because she trusted me a bit more now, but still far too tight to fuck her. I spent long minutes trying to get her to relax.

I needed no additional invitation, but I was going to need Rosie’s help for this next part. When I felt like I’d die if we didn’t move forward, I surprised her when I reversed our positions, putting her atop me and holding the swell of her hips with both hands. She was so much smaller than me, and so light that it was easy to do. She made a little squeal of delight when she realized what was happening. I rolled a condom on myself, feeling unreal.

“You’re in control,” I told her, lining us up and watching her eyes slip half-closed when she felt the tip against her opening. “It’s totally up to you.” She rubbed her hips down, seeking friction on her clit, and making me be the one to gasp when she did it again, and then again. “Go as slow as you need to. Nothing you could do would ever disappoint me.”

Rosie looked down at me, smiling. I suspected she liked me like this, desperate for her and totally at her mercy. I was possible that I was creating a sex monster, but I was much too horny to care. She descended downwards and relaxed, little by little. She was letting me in—inch by inch—but her little pussy was tighter around my cock than a clenched fist. It was agony and ecstasy wrapped into one. I struggled to be still and let her control everything about this moment.

This woman is going to be the death of me, I thought to myself.

I’d told her to go slowly and gently, but her expression was quickly becoming one of total determination. She obviously had no interest in either slow or gentle. Instead, she worked her curvy hips right on down like it was a personal challenge not to stop.

Alright. Go on, baby. Take me. I know you can.

She knew it too. She grinned in a shy, blushing victory that she made it all the way down. Her full tits swayed to and fro, as she smiled, hypnotizing me.

“Are you ok?” I asked, panting against the pressure her inner walls were exerting on my cock. The effort of staying still was threatening to kill me. I needed to ease it. I needed to move. But first, I needed to know that she was alright.

She nodded. “It doesn’t hurt.” The fact that she seemed halfway surprised put a smile on my face. “It pinched for a moment, but that’s all.”

Thank god. Because I can’t wait any more.

Getting her back under me had been as easy as putting her on top had been. She squealed again as we rolled, wrapping her legs around me and squeezing my forearms. Now it was my turn to be in control again. And I had no plans to give it back to her until we both came.

The first pump of my hips against hers felt almost impossibly tight. She gasped, clutching at my arms and then nodding. She wanted more? Good. I gave it to her.

I rode her pussy with the same relentless rhythm I’d used on her with my mouth. I was pushing into her much harder than I intended, but my control was all but spent. I had to trust her to tell me to stop if I was hurting her, because she felt too tight, too hot, and too damn good to hold back otherwise.

The remaining stuff on my desk fell off with each thrust, keeping pace for us like a metronome. Soon, Rosie’s little gasps and sexy moans punctuated the muffled thumps. She caught on to my movements, rocking her hips in perfect time.

I kept pushing, kept moving, kept giving her what we both needed so desperately. The heat and friction was driving me out of my mind, and I didn’t care. Before long, her little body yielded totally to mine. She went pliant, loose-limbed, and soft. Her eyes went vacant and she was panting and flushed. She was close.

A few more desperate thrusts and she was there. When her climax shook her, Rosie clenched so tightly around me that I was pulled right with her into orgasm. I came inside her, moaning her name against her ear. The force of my climax temporarily blinded me, clearing my brain of all thought beyond primal, complete pleasure. Any rational, complex brain function was pushed out to make room for that singular moment of bliss.
