Erotica Sex Story: Kristin always runs the game. Until some IT guy flips the script on her. It only lasts a moment, but now she’s wondering if maybe, just maybe, she didn’t hate it. And she’s not sure what to do with that.

Caution: This Erotica Sex Story contains strong sexual content, including Ma/Fa   Consensual   Heterosexual   Fiction   Oral Sex   Caution   .

Author’s Note: There is a moment towards the end where the gentleman friend is a little rough / aggressive but it falls short of even reluctance, IMO. If that unsettles you, give it a pass and read another story.


In the office break area, Kristin Carter leaned against the counter, her fingers dancing over the buttons of the espresso machine like she was attempting to play a piano recital. She pouted, her reflection in the metal surface showing more frustration than her usual carefree demeanor.

“Come on, you Italian piece of junk,” she muttered, pressing another combination with all the grace of a toddler attempting their first video game controller. A burble and hiss answered her, but no coffee emerged.

A warm, low voice broke through her mini tantrum. “You’re going about it all wrong.”

Kristin turned to find Mark Turner, one of the newer IT guys, lounging in the doorway. He was tall, lanky even, with a mop of dark hair that looked perpetually windswept. His gaze met hers, steady and calm, unlike most men who crumbled under her direct stare.

“Is that so?” Kristin raised an eyebrow, a challenge. She pushed off from the counter, her hips swaying slightly in her form-fitting dress. “And what makes you think you know better than me?”

Mark stepped forward, his long stride eating up the distance between them. He didn’t falter under her scrutiny, instead holding out a hand for the espresso cup she’d been struggling with. “Because I’ve had to learn how to operate this beast every time I need a caffeine fix.”

Kristin handed him the cup, her fingers brushing against his in a deliberate move. She watched as he filled it with water, then pressed a sequence of buttons that were clearly familiar to him. The machine whirred to life, grinding beans and steaming milk like a symphony under his control.

“There,” Mark said, handing back the now full cup. “Just like that.”

Kristin took a sip, her eyes never leaving his. The coffee was perfect, just how she liked it - strong and bitter with a touch of sweetness. She let out a soft hum of approval. “You know, most men wouldn’t dare correct me.”

Mark chuckled, leaning back against the counter beside her. His shoulder brushed hers, but he didn’t pull away. Instead, he turned to face her, his voice low. “And why’s that?”

Kristin smirked, taking another sip of her coffee. “Because they’re afraid I’ll eat them alive.”

Mark laughed, a genuine sound that sent shivers down Kristin’s spine. She felt a flicker of intrigue, something she hadn’t felt in a long time. Most men were too eager or too timid, neither of which was interesting.

“I’m not most men,” Mark said, his gaze never wavering from hers.

Kristin leaned in slightly, her voice dropping to a conspiratorial level. “No, you’re not.” She paused, then added, “You know what we need? Somewhere more comfortable for this conversation.”

Mark raised an eyebrow. “Oh yeah? And where did you have in mind?”

Kristin grinned, pushing off from the counter and straightening her dress. “My office, of course. It’s much more ... private there.” She turned to walk away, then glanced back over her shoulder at him. “Coming?”

The challenge was clear in her eyes, a silent dare that she knew most men couldn’t resist. As she left the break area, she could feel Mark’s gaze on her, steady and sure. The tension between them built like a storm rolling in, promising something intense and unpredictable.

By the time they reached the quiet second floor, Mark had started to suspect that Kristin’s “office” was not listed on any company floor plan.

She finally paused at a little used bathroom.

Mark observed, “Your office?”

She smirked and said, “Close enough”, stepping into the empty room, leaving the door open behind her. She knew Mark would follow - after all, he was anything but unpredictable. And for once, Kristin felt truly intrigued by what came next.

Kristin slipped into the bathroom, Mark close behind her. She locked the door, a soft click echoing in the quiet room. Turning to face him, she leaned against the counter, her eyes gleaming with mischief. “So, Mr. IT Guy,” she began, tracing a finger along his chest, “what are we doing here?”

Mark stepped closer, his hands finding her hips. He was tall enough that even in her heels, she had to tilt her head up to maintain eye contact. “I think you know exactly why we’re here, Kristin.” His voice was low, steady.

She smirked, biting her lip slightly. “Oh? And what makes you think I wanted anything more than a quick chat?”

Mark’s hands tightened on her hips, pulling her closer. He leaned down, his breath hot on her ear. “Because you’re not the type to waste time with small talk.”

Mark’s hands moved to her hips as they kissed, their mouths hungry for each other.

“Your lips are so soft,” he murmured against hers, his fingers digging into her sides.

Kristin smiled into the kiss, her arms wrapping tighter around him. She felt a rush of excitement at how much she was enjoying this - the taste of him, the feel of his skin, the way they were devouring each other.

“Yours are hard,” she whispered back, her mouth trailing down to his neck. “I like that,” she whispered.

As they kissed, Kristin’s hands found his shirt, pulling it up and over his head. She ran her fingers along the defined muscles of his chest and stomach, feeling a thrill at how toned he was.

Mark groaned into their kiss as she touched him, his arms tightening around her waist. He pulled back slightly, his eyes dark with desire as they looked into each other’s faces.

“I want to see you,” he said, his voice husky.

Kristin nodded, stepping out of her heels and the dress that was now pooling at her feet. She stood before him in her lingerie, feeling a surge of confidence as Mark’s eyes roamed over her body.

“You’re beautiful,” he whispered, his hands tracing the curves of her hips.

She smiled, reaching for him again. “Shut up,” she said playfully, tugging him forward.

Mark’s lips met hers once more and they were lost in their kiss, all thoughts of anything else forgotten as their passion took over.

But even as they made out, Kristin couldn’t shake the feeling that there was something missing - a spark, a connection that went beyond physical attraction. She pushed it aside for now, focusing on the moment, but she knew it would come back to haunt her eventually.

As they finally broke apart, gasping for air, Mark reached for his belt and Kristin’s heart skipped a beat at what was about to happen next.

Kristin’s hands slid to the waistband of Mark’s boxer briefs, tugging them down his hips. He groaned as she pulled him free, his erection springing up against her palm.

“You’re so big,” she breathed, her voice husky with desire. He wasn’t the biggest she’d seen, not even close, but enthusiasm counted for something.

Mark chuckled, running his hands over the curves of her hips and down to the waistband of her panties. “I know,” he said, a hint of amusement in his eyes.

Kristin nodded, her grip tightening on him as she pushed him back onto the counter. She knelt before him, the cool tile beneath her knees a stark contrast to the warmth of Mark’s body.
