"Hey, can you grab me that file from the cabinet?" Lisa's voice cut through the quiet hum of the office. She didn't look up from her computer, her feet comfortably propped up on the edge of her desk.

Mark, her assistant, glanced over from his spot by the coffee machine. "Sure thing," he replied, moving towards the cabinet. As he reached for the file, his eyes caught a glimpse of Lisa's feet, perfectly pedicured and slightly arched, emphasizing their length.

Lisa noticed his gaze and smirked, wiggling her toes slightly. "Like what you see?" she teased, her voice low enough to keep their conversation private.

Mark cleared his throat, handing her the file. "Just admiring the view," he admitted, his cheeks flushing slightly.

Lisa laughed softly, setting the file aside. "You know, I've been thinking..." she paused, her eyes locking with his, "about how much I enjoy having you around."

Mark leaned against her desk, intrigued. "Oh? How so?"

"Well," Lisa leaned back, her feet now resting lightly on his thighs, "you make the day more... interesting." Her feet began a slow, deliberate massage, pressing gently into his muscles.

Mark swallowed hard, his eyes flickering down to her feet then back up to her face. "I didn't know you were into... this kind of thing," he managed to say, his voice husky.

Lisa's smile turned sultry. "There's a lot you don't know about me, Mark," she whispered, her feet now tracing patterns on his crotch, feeling the growing bulge beneath his pants.

"Lisa..." Mark groaned, grabbing her ankles, his grip firm but gentle.

"Shh," she hushed him, removing her feet from his grasp and standing up. She closed the distance between them, her hands reaching up to cup his face. "Let me show you," she murmured, her lips brushing against his ear as she led him towards the small sofa in the corner of her office.

She pushed him down gently, her eyes never leaving his as she straddled his lap, her skirt riding up provocatively. "Feel how much I want you," she breathed, her hands guiding his to her hips, grinding slowly against him.

Mark's hands gripped her tightly, his breaths coming faster as he felt her heat through the thin fabric of her panties. "God, Lisa," he muttered, his head falling back against the sofa.

Lisa leaned down, her lips trailing kisses along his jaw, her hands unbuttoning his shirt. "Tell me what you like," she demanded, her voice thick with desire.

"Everything," Mark gasped, his hands roaming under her blouse, finding her nipples hard and ready.

Lisa chuckled softly, nipping at his earlobe. "Not good enough," she teased, her feet now back in action, sliding down his body to rest just above his straining erection.

Mark shuddered, his eyes closing as her feet encased him, gently massaging through the fabric. "Your feet... on me..." he stammered, his control slipping.

Lisa grinned, her feet increasing their pressure. "Yes, my feet," she repeated, watching his face contort with pleasure. "And you have no idea what else I can do with them."

Her words hung in the air, charged with promise, as she leaned closer, her breath hot against his neck. "Stay with me after work, Mark. We'll explore this... together."

Mark nodded, his eyes opening to meet hers, a mix of desire and uncertainty reflected back. "I'm here, Lisa," he assured her, his hands gripping her tighter.

"Good," she whispered, her feet still working their magic, "because I plan to make tonight unforgettable."

With that, she stood up, smoothing her skirt, her eyes sparkling with mischief. "Now, let's get some work done, shall we?" she said, her tone light, masking the intense heat that lingered between them.

The office lights dimmed as the evening set in, casting long shadows across the room. Lisa sat at her desk, a subtle smile playing on her lips as she glanced at Mark, who was busy organizing files nearby. The air was thick with tension, a palpable charge that neither could ignore.

"You ready for that exploration?" Lisa asked, her voice low and husky, breaking the silence.

Mark looked up, his eyes dark with desire. "More than ready," he replied, setting the files down and walking over to her. He leaned against her desk, close enough to feel her breath on his face.

Lisa's feet, still bare, found their way back to his thighs. She traced lazy circles with her toes, watching his reaction closely. "I think you'll like this," she murmured, her feet sliding higher, teasing the sensitive skin beneath his shirt.

Mark groaned, his hands capturing her ankles, guiding her feet to rest just above his belt. "God, Lisa, you're killing me," he admitted, his voice rough with need.

"Good," she whispered, standing up to close the distance between them. Her hands slid around his neck, pulling him closer for a deep, searing kiss. Their tongues danced together, a fierce battle of passion and control.

Breaking the kiss, Lisa led him back to the sofa. She straddled him again, her skirt riding up to reveal more of her toned legs. "Take off your clothes," she commanded, her voice firm yet seductive.

Mark obeyed without hesitation, his hands shaking slightly as he undid his belt and zipper. Lisa watched, her eyes burning with lust, as he revealed himself fully to her.

"Beautiful," she breathed, her hands reaching out to touch him. She guided him inside her, a sharp intake of breath escaping her lips as he filled her completely. They moved together, slow at first, then faster, each thrust matched by a corresponding grind of her hips.

Lisa's feet were back in action, her toes curling around his calves, urging him on. "Yes, Mark, just like that," she encouraged, her voice cracking with pleasure.

Mark's hands gripped her hips, his movements becoming more urgent. "Lisa, I can't hold back," he panted, his body tense with impending release.

"Then don't," she whispered, her own climax building rapidly. With one final, powerful thrust, they both shattered into pieces, their bodies shuddering with the force of their orgasms.

Breathing heavily, Lisa collapsed onto his chest, her fingers tracing idle patterns on his sweat-slick skin. "That was... incredible," she managed to say, her voice soft and satisfied.

Mark chuckled, kissing the top of her head. "Agreed," he said, his hands gently caressing her back.

They lay there for a while, the world outside forgotten, lost in the afterglow of their shared ecstasy. When Lisa finally stirred, she looked up at him, a mischievous glint in her eye. "Ready for round two?" she teased, her feet already beginning their gentle assault on his senses.

Mark groaned playfully, his body responding instantly to her touch. "Always," he replied, pulling her closer for another kiss. The night was young, and the possibilities endless.
