She spreads her legs wider, hiding nothing from me. I press my thumb against her asshole and feel her shudder, her hips jerking up in silent invitation.
"My greedy little slut," I praise, slowly pushing my thumb inside her, watching the way her tight little asshole spreads around it.
She rocks against me, her whole body shaking, and I know she's already close. But I keep her balanced on the edge with my thumb in her ass and two fingers in her cunt, until she's panting through the gag, her hands clawing at the edge of the desk.
"Good girl," I say.
She whimpers in response, the sound muffled.
I unzip my pants, freeing my cock. I'm already hard, precum dripping from the slit, desperate for her. I rub the tip against her clit, teasing her until her whole body goes taut with frustration.
When she's whimpering, I push inside, burying myself in her with one hard thrust.
She cries out, the sound muted by the panties in her mouth. I fuck her slow at first, letting her feel every inch, every drag and pull, until she's wild beneath me, her hands clawing at the desk, knocking shit off the side.
"I love when you're fucking desperate like this," I murmur, yanking her ass up higher. "I love when you want to come so fucking badly, you'll let me do whatever I want to do."
I spit on my fingers, spreading her asshole open again, first one finger, then two, then three. She falls forward, her cheek against the desk, rocking back against me. Little mewls and whimpers escape around the gag, every sound perfect.
I pull my fingers out, pulling out of her to press my cock against her ass.
She looks back at me, pleading wordlessly.
"You want it, princess?" I ask, one hand wrapped around her throat.
She nods once, then again, desperate.
I push in, slowly stretching her open. She hisses, her breath hot against the desk, but she doesn't pull away. She never does.
Once I'm all the way in, I reach between her legs and rub her clit, fast and rough. She comes instantly, her whole body convulsing around me. Her asshole clenches and flutters, milking my cock.
"You love this, don't you?" I snarl, squeezing her waist so tight my fingerprints will be on her for days. "You love it when I use you like this, with dozens of people just down the hall."
She moans in response.
"My whore. My perfect, filthy slut," I groan in awe, pounding into her ass the way she likes. I hear her trying to scream, the sound muffled by the panties gagging her.
I keep one hand at her throat, the other on her hip, holding her in place. She arches back into me, greedy for more.
I drive in harder, savoring the way her body clenches with every thrust. "You feel that, princess?" I rasp, leaning over to bite her shoulder. "You're so fucking tight I could die in here."
Every thrust makes her whimper and buck, her hands scrabbling for purchase on the desk. I slide three fingers inside her pussy, and then another, twisting them until her back arches, and she almost throws herself off the edge.
She's never fucking satisfied, not until I'm knuckles deep, using my whole goddamn hand to wreck her.
I force her knees further apart, lock my hand around her hip, and fist her pussy while I pound her ass. She's so wet, her cunt sucking at my hand like she can't bear to be empty.
She's crying now, tears streaking down her cheeks, but I know the difference between pain and the other thing, the thing she craves most.
"Take it," I growl, fucking her harder. "Take all of it."
I want her to remember this every time she walks into this office. I want the foundation of this entire goddamn business to be the memory of her coming apart for me, gagged and helpless and so fucking desperate.
She comes so hard she nearly blacks out, her body writhing and bucking against my hand and cock in perfect rhythm. The feeling of her coming like this—gagged, helpless, greedy for me—is so fucking intense I almost lose it, too.
I force myself to hold back, just for a second longer, wanting to savor the way she milks me, the way her whole body seems to shudder and lock up, every muscle coiled tight. The desk shakes beneath us, a few more things crashing off the far side as she thrashes, the sound of it drowned by the guttural sounds spilling out around the gag.
When she finally stops shaking, I pull out and stroke my cock, watching the way her ruined, gaping asshole clenches and relaxes, slick and swollen and so fucking beautiful.
