Fiona, the 28-year-old freelance illustrator who spent her days turning caffeine and deadlines into colorful book covers that paid just enough to cover ramen and rent, eased her dented Civic into the curving driveway of Grant’s house. Grant was the 34-year-old senior designer at the agency where she sometimes embedded for week-long sprints, the one with the perpetual five-o’clock shadow and the habit of leaning over her tablet to murmur, “That line work is making me throb, Fiona.” She had laughed it off as harmless office flirting. Now she was here for the entire weekend, watering his monstera and pretending she wasn’t curious about what the rest of his life looked like.

She killed the engine and sat for a moment, drumming her fingers on the wheel. For six months she had been sexting an anonymous account named ShadowTease42 on a no-strings adult forum. The chats had started silly—bad puns about perspective and shading—then slid into filthy, laugh-out-loud detailed fantasies that left her touching herself in her tiny apartment with the lights off and her laugh turning into breathy little moans. She had begged him more than once to reveal himself. He had always answered the same way: When you’re ready to play in the real world, I’ll show you exactly who I am.

Now she was house-sitting for the flirtiest coworker she had. Coincidence was a hilarious bitch.

“Stay professional, Fiona,” she told herself, hauling her duffel out of the trunk. “Water plants. Sketch that deadline cover. Do not sniff his pillow like some budget Sherlock Holmes with a masturbation problem.”

The house was exactly the kind of place a man with good taste and a better salary would own: clean lines, warm wood floors, massive windows that looked out over a backyard pool glowing turquoise under the security lights. She kicked off her sandals in the foyer, wiggling her bare toes against the cool tile, and gave herself a tour like a nosy real-estate agent.

The kitchen was all stainless steel and expensive coffee equipment. The living room had a sectional big enough for an orgy and a TV that probably cost more than her car. She found the monstera—lush, dramatic, slightly dramatic—and gave it a dramatic little salute. “Your dad’s hot, plant. Don’t tell him I said that.”

Upstairs, the guest room was cute and impersonal. She dropped her bag on the bed, then paused. The master bedroom door was ajar, like an invitation. Her pulse gave a ridiculous flutter.

“Just a peek,” she whispered, already walking toward it.

Grant’s bedroom smelled like him—sandalwood, a hint of citrus, and something darker that made her thighs press together. The bed was enormous, dressed in slate-gray sheets so soft they looked illegal. A single cream envelope rested dead-center on the pillow like a wink.

Fiona’s stomach flipped. She crawled across the mattress on all fours, the movement making her jeans rub distractingly against her clit. The envelope had her name on it in handwriting she had seen on sticky notes at the office a hundred times. Her mouth went dry.

She tore it open.

Fiona,

Yes, it’s me. ShadowTease42. The man who’s spent six months learning exactly how wet you get when someone tells you to edge until you’re shaking. I’ve known it was you since the third conversation. You type the same way you draw—bold, teasing, a little filthy. I’m Grant. Surprise.

If you want the real me when I get back on Sunday, here’s your dare. I want you in my bed, naked, touching that pretty pussy like you’ve been fantasizing about doing while we’ve been typing dirty messages under our desks. I want you loud. I want you messy. Do it, and I’ll finally show you who’s been making you laugh and ache at the same time.

No pressure. But I bet you’re already smiling that nervous little smile I love.

—G

Fiona dropped the note like it had bitten her. Then she snatched it back up and read it again, a high-pitched giggle bursting out of her.

“Oh my god. Grant. The man who brings those disgusting kale smoothies and still manages to look like sex in business casual. He’s been ShadowTease this whole time?” She flopped onto her back, pressing the letter to her chest. Her nipples were already tight against her bra. “This is either the best weekend of my life or the most awkward Monday morning in corporate history. There is no in-between.”

She stared at the ceiling, heart hammering, a ridiculous grin spreading across her face. The tension felt electric, like the air before a thunderstorm. Part of her wanted to text him immediately and call him every name she could think of. The other part—the part currently throbbing between her legs—wanted to see how far this game could go.

That was when she noticed the second envelope on the nightstand, propped against a sleek black box wrapped with a simple silver ribbon. Her laugh this time was half moan.

“You absolute menace.”

She opened the second note.

Caught you crawling across my bed like a curious kitten. If you’re reading this, you didn’t run. I’m sitting in an airport lounge with a hard-on the size of my ego, picturing you right now. Inside the box is a brand-new vibrator. Curved. Quiet. Eight settings, all of which I want to hear you test. Use it exactly how I’m about to describe.

Strip. Lie on my sheets. Spread your legs like you own the place—because tonight you do. Tease your clit until your thighs are shaking. Slide the toy inside that soaked little cunt and edge yourself three times. No coming until I say so. Then text me every filthy detail at the usual account. I’ll be watching my phone like it’s the best show on earth.

P.S. I picked the color because it matches the shade you turn when you’re embarrassed and turned on at the same time. You’re probably that shade right now. Cute.

Fiona opened the box. The vibrator was gorgeous—matte black, elegantly curved, with a thick bulbous head and a fluttering clit stimulator that made her mouth water. It felt expensive and wicked in her palm.

“Jesus, Grant, did you register for this at a sex shop? ‘Dear registry, my coworker might masturbate in my bed, please send the premium model.’”

She was laughing, actually laughing, while her pussy clenched hard enough to make her whimper. The combination was heady. Humor and heat tangled together until she couldn’t tell which was making her wetter.

Her phone was already in her hand. She opened the familiar anonymous chat and typed with fingers that only shook a little.

Fiona: So. Grant. You magnificent bastard. I found both notes. The vibrator is ridiculous and perfect. I’m officially confirming I’m into this. Like, stupidly into it. But just so we’re clear—this is all fun and consensual and I can stop anytime, right?

The reply came so fast she yelped.

ShadowTease42: Fuck yes, Fiona. 100% consensual. I want you dripping because you want to be, not because you feel trapped. You have no idea how hard I am right now knowing you’re in my bedroom holding that toy. You staying?

Fiona: I’m staying. I’m also laughing my ass off because this is the most ridiculous house-sitting experience in human history. You’ve been my anonymous crush this whole time? The kale smoothie guy?

ShadowTease42: Guilty. I’ve been hard in every single meeting we’ve had since I figured it out. Now be a good girl and start stripping for me. Tell me what you’re taking off first. I want details.

Fiona’s breath hitched. She stood up beside the bed, cheeks burning, a grin she couldn’t kill stretching her mouth.

Fiona: Tank top coming off. Black bra underneath. My nipples are already stupidly hard. This is your fault.

ShadowTease42: Good. Pinch them. Hard. Tell me how it feels while I sit here pretending to read emails and imagining my mouth on those tits.

She did. The sharp little zing of pleasure made her knees wobble. “Oh my god,” she muttered to the empty room, laughing breathlessly. She typed one-handed.

Fiona: Pinching now. Feels so good it’s stupid. My laugh sounds ridiculous while I’m horny, doesn’t it?

ShadowTease42: I love that fucking laugh. Jeans next. Slow. Describe those curvy hips I’ve been staring at for months.

Fiona popped the button, shimmying the denim down thick thighs that jiggled just enough to make her feel deliciously filthy. She kicked the jeans away and stood in nothing but black lace panties, skin flushed pink.

Fiona: Jeans gone. Panties are soaked. Like, embarrassingly soaked. I’m standing in your bedroom in my underwear laughing at how surreal this is.

ShadowTease42: Take them off. Lie down on my sheets. Spread your legs and touch that pretty cunt for me. I want to know how wet you are. Be detailed, illustrator girl. Paint me a picture.

She stripped the panties off, the lace clinging to her slick folds for a second before she tossed them. Naked, she crawled back onto the bed, the cool sheets kissing her overheated skin. Her full breasts swayed as she moved; her nipples grazed the fabric and she moaned.

Lying back, she spread her thighs wide, feeling the obscene stretch of exposure. Her pussy was puffy, glistening, clit peeking out and begging. She ran two fingers through her folds and gasped at how slippery she already was.

Fiona: I’m naked on your bed. Legs spread like a slutty starfish. My pussy is dripping all over your fancy sheets. Two fingers sliding over my clit right now and it feels so fucking good I might cry. Or laugh. Both. Definitely both.

ShadowTease42: That’s my girl. Circle that clit slow. Imagine it’s my tongue. I’ve jerked off thinking about how you’d taste for months. Now pick up the vibrator. Turn it on low. Tease yourself with it while you keep texting me. I want you right on the edge before you slide it in.

Fiona grabbed the toy, thumbed it on. The low, powerful hum filled the room. She pressed the fluttering tip to her swollen clit and her back arched clean off the bed.

“Fuck—Grant—” The moan tore out of her, loud and shameless. She typed frantically with one hand, hips already rocking.

Fiona: It’s on me. Oh my god it’s perfect. My clit is throbbing. I’m laughing and moaning at the same time like a crazy person. I’m so close already and I haven’t even put it inside yet.

ShadowTease42: Edge for me. Don’t you dare come. Tell me how tight you are. How bad you want to be filled.

She kept the toy moving in lazy circles, dipping it lower to nudge her entrance, then back up. Her thighs trembled. The pleasure coiled tighter and tighter.

Fiona: I’m so tight and so wet the toy is already shiny. I want you to watch me fuck myself on your bed. I want you to come home and replace this toy with your cock. I’m edging—fuck—I’m right there—

She pulled the vibrator away at the last second, gasping, laughing shakily as the orgasm retreated like a wave sucking back from shore. Her whole body buzzed.

The phone buzzed again.

ShadowTease42: Good girl. Again. This time slide it inside while you rub your clit. I want you stuffed full and desperate. And Fiona? When you’re shaking on that third edge, I have another dare waiting for you downstairs. Something even filthier.

Fiona’s eyes widened, a fresh spike of nervous, delighted tension shooting through her. She was naked, soaked, laughing, and so turned on she could barely type straight. The vibrator hovered above her dripping entrance, humming impatiently.

She pressed send on her next message, voice husky in the quiet room.

Fiona: You’re evil and I’m obsessed. Starting the second edge now…

The tension stretched tighter, the night suddenly full of possibilities, and Fiona had never been more awake in her life.

Fiona pushed the vibrator deeper on that second edge, the curved shaft stretching her slick walls as her fingers danced tight circles over her swollen clit. The dual assault made her hips buck involuntarily, her full breasts jiggling with the motion, nipples tight as pencil erasers in the cool air of Grant’s bedroom. At twenty-eight, she knew her body well—knew how her freelance illustrator’s ass got sore from too many hours at the drafting table, knew how her thick thighs could tremble like this when the pleasure coiled just right—but this was different. This was Grant’s bed, Grant’s toy, Grant’s filthy game, and the absurdity of it all bubbled out of her in a throaty laugh that shook her belly.

“Listen to that,” she gasped aloud, reading the latest text he’d fired off in real time. “ ‘I bet that pretty cunt is gripping my gift like it’s the only cock you’ve ever needed. Tell me how full you feel, illustrator girl.’ God, Grant, you magnificent kale-smoothie bastard, I am full. It’s buzzing right against that spot that makes my eyes cross, and I’m so wet it’s dripping down my ass crack onto your fancy sheets. I sound ridiculous, don’t I? Moaning and laughing like some budget porn parody of myself.”

Her voice cracked into another giggle as the edge rushed closer, thighs already quivering. She pumped the toy in shallow thrusts, fingers never stopping their relentless circling, the wet sounds loud and obscene in the quiet house. I’m actually doing this. House-sitting for the coworker who flirts like breathing, and I’m two edges deep into the sluttiest solo session of my life. If my deadlines could see me now they’d file for divorce. The thought only made her wetter. Right before the wave could crest she yanked the vibrator free, leaving her pussy clenching on nothing, a needy whine mixing with her breathless laughter.

The phone buzzed again. She snatched it up, eyes scanning his newest message, and read it out loud in a husky, teasing singsong. “ ‘Good girl. One more edge, then I want you to get creative. Pillow under those hips. Ride that toy like you’re fucking me in cowgirl while you read every filthy thing I’ve said back to you. Loud. I want to hear you describe how ridiculous and soaked you are. Pretend I’m watching from the doorway.’ Oh my god, you evil genius.”

Fiona’s pulse hammered. She stacked one of his pillows in the center of the massive bed, the slate-gray fabric already damp from her earlier mess. The vibrator, glistening with her arousal, stood proud when she wedged its base into the pillow’s plush top. She swung a leg over, straddling it in true cowgirl, her curvy hips hovering as she lined up the thick head with her entrance. Lowering herself felt decadent—every inch spreading her open again, the clit stimulator nestling perfectly against her throbbing nub. “Here we go, ShadowTease. Or should I say Grant? I’m reading your words while I do this, just like you ordered.”

She rocked experimentally, the toy spearing up into her as she braced her hands on the headboard. Her breasts swayed heavily beneath her, nipples grazing the cool air with every bounce. “First text,” she recited, voice breaking into a moan as she took him—well, it—to the hilt. “ ‘I’ve jerked off thinking about how you’d taste for months.’ Fuck, Grant, saying that out loud while I’m riding this thing is making me clench so hard. I’m ridiculously wet. Like, embarrassing, laugh-out-loud wet. You can probably hear the squelch from the airport. My thighs are shaking already and I’ve barely started.”

Another text pinged through. She laughed—actually cackled—as she read it mid-ride. “ ‘That’s my girl. Bounce harder. I want those gorgeous tits bouncing while you tell me how silly you feel fucking a toy in your coworker’s bed.’ Silly? Try certifiably insane. I’m twenty-eight years old, paying rent with book-cover gigs, and I’m naked in your bedroom pretending this vibrator is your cock. My pussy is creaming all over it, Grant. Look—well, imagine—how it shines every time I lift up.” She rose and sank again, faster now, the pillow creaking under her knees, her ass cheeks rippling with the effort. The fluttering stimulator against her clit sent lightning up her spine. She kept reading his earlier messages aloud between moans, each one filthier than the last, her voice growing louder and more broken.

“I’m so wet it’s ridiculous… dripping down the toy… making a mess of your sheets like a horny cartoon character… oh god, I’m edging again but this time I don’t want to stop.” Her laughter mixed with genuine whimpers as she ground down hard, circling her hips so the vibrations hit every sensitive inch inside her. She imagined him watching—those perpetual five-o’clock-shadowed eyes dark with lust, leaning in the doorway exactly like he did over her tablet at the office. “Are you watching me, Grant? Is this what you wanted? Your house-sitter turned porn star, tits bouncing, thighs quaking, telling you out loud how stupidly soaked and ridiculous I feel? Because I do. I feel like the punchline to the hottest joke ever told.”

The pressure built mercilessly. She rode harder, one hand dropping to pinch a nipple while the other braced for leverage. Her thighs burned, muscles jumping uncontrollably as the orgasm barreled closer. “I’m gonna come—fuck, I’m gonna come so loud—reading your last text while I do it: ‘When you’re shaking on that third edge, I have another dare waiting for you downstairs. Something even filthier.’ Well the filthiest thing right now is me, you idiot, coming all over your gift while laughing my ass off—”

The climax detonated. Fiona’s head snapped back, a loud, shameless cry ripping from her throat that dissolved into helpless giggles. Her thighs shook violently, knees digging into the mattress as her pussy spasmed around the buzzing toy in rhythmic, powerful waves. She kept rocking through it, drawing every last pulse out, her juices flooding over the vibrator and the pillow beneath. The orgasm rolled on, thigh-quaking and loud enough that she half-worried the neighbors might call the cops, all while she pretended those dark eyes were drinking in every second. “Watch me, Grant… fuck, watch your ridiculous girl fall apart…”

When it finally ebbed she collapsed sideways, chest heaving, a sheen of sweat making her skin glow under the low bedroom lights. The vibrator slipped free with a wet pop and she switched it off, staring at the glistening thing in her hand. A fresh wave of giggles overtook her—bright, post-orgasm laughter that left her flushed from chest to cheeks. “I can’t believe I did that. I rode a pillow. In cowgirl. While monologuing your sexts. I’m never going to be able to look at that monstera plant the same way again.”

Still giggling, she grabbed her phone, angled it for the perfect cheeky afterglow selfie: face flushed and satisfied, hair a wild mess across the pillow, one leg still lazily spread to show the glistening aftermath between her thighs. She held the used vibrator up beside her cheek like a trophy, tongue poking out in playful victory. The caption she typed was simple: Dare completed. Afterglow level: expert. Your move, Shadow.

She hit send.

The reply came faster than any before.

ShadowTease42: Jesus Christ, Fiona. That picture just killed me. I’m actually parked two streets away. Never got on the plane. I’ve been sitting in my car like a nervous idiot, hard as a rock, waiting to see if you’d play. Do you want the real thing next?

Fiona stared at the screen, heart stuttering, then burst into fresh laughter that shook her whole naked body. Her fingers flew.

Fiona: Get in here, idiot.

She tossed the phone aside, stretched luxuriously, and arranged herself in the center of his enormous bed—naked, legs slightly parted, skin still pink from the orgasm, a wicked grin splitting her face as she waited for the sound of the front door. Her pulse raced with anticipation, every inch of her buzzing.

Because in the end the biggest joke was that she had been ShadowTease42 first, the one who started their anonymous game six months ago under a fake persona just to lure the flirty coworker she wanted so badly, and now the tease had finally, perfectly, reversed on them both.
