As the sun began to set, Karen and Liam found themselves alone in the office. It was rare for them to be alone together and even rarer for them to have the entire office to themselves. They were both aware of the tension that had been building between them throughout the day and decided to take advantage of the opportunity.

Karen glanced over at Liam's desk and saw that he was already hard at work. She couldn't resist sneaking a peek at his crotch and noticed that he was sporting an impressive bulge beneath his pants. Her heart raced with excitement as she made her move.

With a confident stride, Karen walked over to Liam's desk and leaned against it. She crossed her arms over her chest, revealing a hint of cleavage in her tight blouse. "Can I ask you something?" she purred.

Liam looked up at her, his eyes wide with surprise. He couldn't believe his luck—Karen was finally making a move on him. "Of course," he replied, his voice cracking slightly.

Karen leaned in closer, their bodies only inches apart. She could feel the heat emanating from him, and it made her even more turned on. She slowly reached down and undid the button of his pants, her fingers brushing against his growing erection. Liam let out a moan as she started stroking him through his underwear.

His mind was racing, but he managed to gather enough courage to speak. "Karen, I've been wanting to do this for so long," he confessed.

She smiled seductively and stood up straight, causing her breasts to graze against his chest. "You mean you've been wanting to see my tits?" she teased, reaching behind her back to undo the clasp of her bra.

Liam could hardly believe his luck, Karen was actually going to do this. As her beautiful breasts sprung free from her bra, he moved his hands to cup them, fondling them gently. Meanwhile, Karen continued to stroke Liam's hard cock, her other hand exploring his chest and stomach.

Their clothes quickly became a hindrance, so they both quickly shed them, revealing their naked bodies to each other for the first time. Liam gasped when he saw how beautiful Karen was, every inch of her body was flawless. She was just as taken aback by him.

"You're even more gorgeous than I thought," she breathed, running her hands down his chest and stomach before moving lower to trail her fingers across his erect cock.

Liam moaned loudly as Karen began to stroke him, her warm hands sending waves of pleasure through his body. He leaned forward, capturing one of her nipples in his mouth, sucking on it hungrily. This only served to fuel their desires further.

As Karen gasped in delight, Liam managed to push her chair back, revealing her wet pussy. He didn't hesitate for a moment; he plunged his cock deep inside her, filling her up completely. They both groaned in unison as they finally consummated their long-awaited passion.

Their lovemaking was intense and primal, fueled by the adrenaline of being caught in the act. They moved together, their bodies slippery with sweat and desire. As they neared orgasm, Karen reached between them and wrapped her fingers around Liam's cock, stroking him in time with her movements.

It was too much for Liam—he exploded inside Karen, filling her with his hot cum. She cried out in ecstasy as she followed him over the edge, her pussy squeezing his cock tightly as she came.

As they caught their breath, they looked into each other's eyes, both completely overcome with desire. From that moment on, they were inseparable, not only as coworkers, but also as lovers. They continued to work on their project, but now they had something even more interesting to talk about during their late-night office sessions.
