Emily Harper’s fingers drummed once on the steering wheel as she eased the SUV into the usual shadowed corner of the lot, the engine ticking cool in the early-evening hush. Jake was already lost in the back seat, earbuds clamped tight, thumbs tapping some game that kept him blind to everything else. She had dressed for war tonight—long trench coat belted loose over her skin even though the air was mild, the wool brushing her bare thighs like a secret promise. Beneath it, nothing but the black crotchless lingerie she had ordered in secret and slipped on in her bedroom mirror an hour ago: sheer lace cups that framed the heavy undersides of her breasts without covering the nipples, thin straps hugging the dip of her waist, and a scandalous open crotch that left her pussy and ass completely bare. The lace whispered against her swollen folds with every shift, already coating the delicate fabric with her slickness. Jake is right outside, she reminded herself, pulse kicking higher. And I’m about to walk into that office dripping for the man who grades his tests.

She stepped out, the coat swishing around her calves, and the cool air licked straight up between her legs. Her nipples tightened instantly against the lace, two stiff peaks visible if anyone looked close enough. The hallway felt longer tonight, every click of her heels echoing like a dare. Mark’s office door stood half-open. She pushed inside, closed it, and locked it with a soft, deliberate click that made the room shrink around them.

Mark looked up from behind his desk, sleeves rolled, tie loosened, and the moment his warm brown eyes landed on her the air changed—thicker, charged. She didn’t speak. She simply unbelted the coat, let it fall open, then shrugged it off her shoulders in one smooth motion. The trench pooled at her feet. She stood there naked except for the black lace that did nothing to hide her, breasts full and framed, pussy glistening and open, ass bare and offered. The cool office air kissed every exposed inch of her.

Mark’s breath caught hard. “Emily ... fuck.”

She crossed the small space, hips rolling with new confidence, and placed one palm flat on his chest. He was already hard beneath his slacks; she could feel the thick line of him straining. “Sit,” she whispered, voice low and commanding. She pushed him gently back into the big leather principal’s chair. The wheels rolled once, then stopped. Mark sank into it, eyes never leaving her body, the chair creaking under his weight like it approved.

Emily climbed into his lap facing away from him—reverse cowgirl, legs spread wide over his thighs—so the first thing he saw was the open crotch of the lingerie and the slick shine of her pussy lips. She reached back, unzipped him with steady fingers, and freed his cock. It sprang up hot and heavy, the head already glistening. She guided it to her entrance, rubbing the thick crown through her folds once, twice, coating him in her wetness, then sank down in one slow, deliberate glide.

The stretch was perfect. She felt every inch open her, fill her, claim her while she stayed completely in control. A low moan slipped from her throat as her ass settled flush against his lap, his cock buried to the hilt. The chair creaked again. She braced her hands on his thighs and began to ride—slow circles at first, grinding deep so the head of him nudged that sensitive spot inside her with every roll of her hips. The lace straps of the lingerie rubbed against her clit on every downstroke, sending sharp sparks through her core.

Mark’s hands landed on her hips, gripping hard, but she caught his wrists and pinned them to the armrests. “My turn,” she breathed, voice husky. “You sit there and take it.” She lifted up until only the head remained inside her, then sank back down with a wet, obscene sound that filled the quiet office. Faster now. Harder. The chair rocked beneath them in rhythm with her movements, leather warm against her bare ass. She could feel his cock throbbing inside her, thick and pulsing, but she slowed every time his hips tried to buck up, drawing it out, making him groan her name like a prayer.

“Emily ... God, you’re so fucking wet.”
