Caitlin rides you

Even though the office door was locked, Caitlin took a deep breath before she moved toward you, her modesty replaced by a ****, rehearsed determination. She reached down, her hands trembling slightly as she hooked her fingers into the waistband of her underpants, sliding them down her legs before moving to your belt. With a quick, frantic series of movements, she freed you from your trousers, her eyes wide as she looked at your hard cock. "It's hard," she murmured.

"Thanks to you."

Emboldened by your words, Caitlin hiked up her skirt and straddled your lap. She guided you inside her with a sharp intake of breath, her eyes fluttering shut as she sank down fully. She began to move immediately, a frantic, rhythmic bouncing that caught you by surprise. She was riding you with an earnestness that bordered on the obsessive, clearly operating under the assumption that this was the "extra work" Samantha had described. She didn't realize that Samantha’s sessions were far more restricted. Caitlin, in her desire to please and her lack of nuance, was giving you everything.

You're not complaining.

As her movements grew more erratic and the friction intensified, a flicker of genuine panic crossed Caitlin’s face. She leaned forward, her large breasts pressing firmly against your chest, her voice a strained whisper against your ear. "Mr. Madison... I just remembered... I'm in my fertile window. I... I'm not wearing any protection today."

You gripped her hips, anchoring her as she continued her frantic pace, the physical sensation of her internal muscles clenching around you reaching a fever pitch. You looked up into her blushing, worried face and chuckled. "Don't worry about that, Caitlin," you grunted, "If that’s the case, you might just be the most productive employee I’ve ever had the pleasure of managing."

The double meaning hit her instantly. The idea of "productivity" in a professional sense clashing with the biological reality of what was happening inside her caused a visible surge of conflicting emotions. Her pupils dilated, a mix of genuine professional worry and a deep, primal arousal washing over her features.

Her pace didn't slow; if anything, she rode you even harder.

You felt the inevitable surge building, the pressure becoming impossible to contain. You pulled her closer, burying your face in the soft, fragrant curve of her neck as your muscles tensed. "Get ready, Caitlin," you whispered, your voice a jagged edge of pleasure. "Here comes your bonus."

You shuddered as you came deep inside her, the heat of the release causing her to gasp and arch her back. You held her there for a long moment, the silence of the office returning as the frantic movement ceased.

As she slumped against you, breathless and overwhelmed, you patted her hip with a final, chillingly professional bit of encouragement. "Well done. If you’re lucky, Caitlin, you’ll be eligible for those maternity benefits much sooner than you anticipated."
