Chapter 290: 290 Sin.

"What?"

"Oh yes. Don’t you know? Using such delightful devices does wonders for helping women relax. Studies have borne it out."

"I see," I said, my voice already husky. Lacey’s hips tilted toward me, her mound pressing deliberately against the hard ridge in my pants. A hot throb of need pulsed through my cock. Dammit, why did she have to be so unbearably sexy?

"Studies that Firefly sponsored?"

"We did have to be sure before we moved to market testing," Lacey hummed, grinding herself against me in slow, filthy circles. I could feel the heat of her through the thin barrier of fabric. "But more testing is always a good idea. Mind lending a hand?"

"You going to turn this into another fucking product?" I asked.

"A fucking product indeed," she answered with a wicked little quirk of her lip, and then she kissed me.

Even knowing Lacey was the kind of corporate predator who would sell her own grandmother for a corner office, I couldn’t deny she knew exactly how to kiss.

Soft at first, then deeper, tongue sliding against mine like she was already negotiating terms with her mouth.

My hands gripped her shoulders and spun her around, pinning her against the edge of the desk. She gasped, then cooed, one leg hooking around my hip to drag me closer.

Clay from whatever experimental compound she’d been demonstrating earlier was drying in faint patches along her collarbone and the tops of her thighs. I didn’t care. My hands roamed over the sleek black leotard that clung to every curve like a second skin.

"Business is going to boom with all this, Miles," she purred against my mouth. "I do hope you make the right decision."

"And what happens if I make the wrong one?"

"You would simply lose an excellent opportunity to make a fortune." Her glasses slipped a fraction down her nose as she looked up at me, eyes gleaming. "Unless... we negotiate further."

I yanked the shoulder straps of the leotard down. Her breasts spilled free—plump, firm, perfect in a way that screamed money, personal trainers, and probably a quiet gene-therapy clinic on the side. Lacey arched, offering them up without shame.

"I warn you," I growled, peeling the rest of the leotard down her body until it pooled at her ankles. "I’m a tough negotiator."

"I believe the word is hard." She kicked the garment away and hooked her leg higher around me, dragging the bare, slick heat of her pussy against the bulge in my pants. "Mmm. Very hard."

She reached between us, palm pressing firmly over my cock through the fabric, and then her voice dropped into something silkier, more dangerous.

"Here’s a better test, Miles. One that will actually tell us something useful." She nodded toward the sleek black case on the side of the desk—the one that had held the prototype massagers and "relaxation devices" she’d been pitching. "Blindfold me. Use that pretty little toy on me... and use yourself. Switch whenever you like. The challenge is simple: can I tell the difference?"

I stared at her.

Lacey smiled, slow and filthy. "If I guess wrong even once, I’ll sweeten the partnership terms in your favor. If I guess right every time... well. Then you sign. And you keep coming back to Firefly for ’follow-up testing.’" She pressed closer, lips brushing my ear. "Deal?"

My cock throbbed so hard it hurt.

"Deal," I rasped.

She reached up, took off her glasses, and set them carefully on the desk. Then she pulled a length of soft black silk from the case—clearly prepared for exactly this kind of demonstration—and handed it to me.

I tied it snugly over her eyes. The moment the world disappeared for her, Lacey’s posture changed. Her breathing deepened. Her thighs parted a fraction wider. A soft, anticipatory shiver ran through her.

"Good girl," I murmured, just to watch her react.

I opened the case. Nestled among the prototypes was a thick, realistic silicone dildo—warm to the touch, weighted, with a subtle curve and enough girth to make most women think twice.

I set it on the desk within easy reach, then shoved my own pants and underwear down. My cock sprang free, flushed dark and already leaking.

Lacey stood naked against the desk, blindfolded, legs slightly spread, waiting. The sight of her like that—corporate ice queen turned obedient experiment—made something dark and hungry uncoil in my chest.

I stepped in close, dragged the head of my cock up the length of her slit once, twice, coating myself in the wetness already gathering there. Lacey’s breath hitched.

"That’s... warm," she whispered.

I didn’t answer. Instead I reached for the toy, warmed it briefly against my palm, and pressed the blunt silicone tip against her entrance. I pushed in slowly—inch by deliberate inch—until the thick shaft was buried deep. Lacey’s mouth fell open on a silent moan. Her hands braced on the desk behind her.

I fucked her with the toy in long, steady strokes, watching the way her pussy stretched around the silicone, the way her inner walls fluttered and clung.

Every time I bottomed out she made a soft, helpless sound. After a full minute of that I pulled the toy free with a wet sound and immediately replaced it with my cock, sliding home in one smooth thrust.

Lacey cried out.

"Which one was that?" I demanded, voice rough.

She swallowed hard, hips rolling to take me deeper. "The real one. You’re hotter. Thicker at the base. There’s a pulse."

I rewarded her accuracy by grinding deep, letting her feel every throb. Then I pulled out, replaced myself with the toy again, and started fucking her harder with it—short, sharp thrusts that made her breasts bounce and her thighs tremble.

"And now?"

"Toy," she gasped. "Smoother. No heartbeat. But—fuck—still so good—"

I kept switching.

Cock. Toy. Cock again. Sometimes I left the toy buried inside her and rubbed the head of my cock against her clit in tight circles until she was whimpering.

Sometimes I fucked her with both at once—toy deep in her pussy while I stroked myself against the stretched rim, letting her feel the dual pressure.

Lacey’s composure cracked further with every exchange. Her voice turned breathy, slutty, the polished executive melting into something rawer.

"Harder—please—I need to feel the difference properly—"

I gave her what she asked for. I bent her farther back over the desk, one hand gripping her hip, the other alternating the toy and my cock with ruthless efficiency. Every time I switched I demanded an answer. Every time she got it right I praised her in a low, filthy voice. Every time she hesitated I punished her with a sharper thrust or a slap to her ass that left a pink print.

Sweat beaded between her breasts. Her thighs were shiny with her own arousal. The wet sounds of the toy and my cock moving in and out of her filled the office. Somewhere in the building people were still working late; the thought only made my blood hotter.

I shoved the toy deep and left it there, then leaned over her, mouth at her ear.

"I’m going to fuck you with my cock now while the toy stays inside. You’re going to take both. And you’re going to tell me exactly how it feels."

Lacey moaned like she’d been waiting for permission to fall apart.

I pushed in alongside the silicone. The stretch was brutal, perfect. Her pussy fluttered wildly around the dual invasion. I fucked her in short, deep strokes, feeling the toy shift against my cock with every thrust. Lacey’s head fell back, blindfold still perfectly in place, mouth open in continuous broken sounds.

"I—I can feel both—your cock is hotter, it twitches, the toy is harder, colder—oh god, Miles, don’t stop—"

I didn’t.

I kept the rhythm punishing, one hand still working the base of the toy so it ground against her front wall while my cock dragged along the opposite side. Lacey’s legs started to shake. Her polished nails scraped the desk. The corporate mask was gone; what was left was pure, shameless need.

"I’m close," she gasped. "Please—let me come—I need to come on both of them—"

"Then come," I ordered. "And keep telling me which is which while you do it."

She shattered with a raw cry, body locking up, pussy clamping down in hard rhythmic pulses around cock and toy alike. I felt every flutter, every gush of wetness. The moment her orgasm peaked I yanked the toy free and buried myself to the hilt, fucking her through the aftershocks with deep, claiming thrusts.

"Your cock," she sobbed, still coming. "That’s your cock—I know it—fill me—"

I did.

I came hard, groaning against her neck, pulsing thick ropes of cum deep inside her while her cunt milked me greedily. The pleasure rolled through me in waves; I kept rocking into her until every last drop was spent.

For a long moment the only sound in the office was our ragged breathing.

I reached up and untied the blindfold. Lacey’s eyes blinked open, glassy and dark with residual lust. A flush stained her cheeks and the upper slopes of her breasts. My cum was already starting to leak from her, sliding down the inside of one thigh.

She looked thoroughly used and completely unrepentant.

I pulled out slowly, watching the way she clenched as if trying to keep me inside. Lacey stayed sprawled against the desk, legs still open, making no move to cover herself.

"Well?" she asked, voice husky. "Did I pass the test?"

"You got every single one right," I admitted.

A slow, satisfied smile curved her mouth. "Then I believe that means we have a partnership." She reached for her glasses, slid them back on, and somehow managed to look like a woman who hadn’t just been fucked senseless over her own desk. "I’ll have the revised terms drawn up by morning. And Miles..."

She trailed a fingertip through the mess between her legs, then brought it to her lips and tasted it without breaking eye contact.

"I expect you to stop by Firefly quite often for further product evaluation. I’ll make sure your new office is very close to mine."

I stared at her—naked, marked, still dripping my cum, already negotiating the next round—and felt my cock twitch with renewed interest.

"I’ll think about the finer points," I said, stepping back in and bracing my hands on either side of her hips. "But first... I believe the testing period isn’t quite over yet."

Lacey’s smile turned pure sin.

"I was hoping you’d say that."
