Continue working with her.

The next day, the office is quiet. You lean back in your chair, having finished your paperwork for the day. There's more, but that can wait. You lean forward to the intercom on your desk and press the button, the speaker crackling to life.

"Gemma," you say, your voice low and commanding.

"Yes, sir?" Her voice comes through the speaker, soft and professional.

You don't answer straight away. Instead, you let the silence stretch, her anticipation building with each passing second. You can hear her breathing through the speaker, the way she grips the pen in her hand tightly.

"Panties off. Hands between your legs," you finally say. "Now."

Immediately, you hear the sound of her chair scraping against the floor and the rustling of fabric. You don't need to see her to know that her panties are already lying in a pool on the floor underneath her desk, her fingers working between her thighs. Your cock hardens in your pants as you recline further in your chair. You pull down the zipper and slide down your underwear, freeing your cock as you hear her fingers move through the slick, wet folds of her pussy.

“Louder,” you command.

She obeys, her breathing quickening, her moans growing louder as she works herself. Your hand tightens around your cock, stroking in time with the sounds of her pleasure. Every now and then, her chair squeaks as her hips move in response to her fingers. The sound of her arousal is obscene, the wet, sloppy noises of her pussy echoing through your office through the tiny speaker on the intercom.

“That’s it,” you murmur, “Just like that.”

You hear her breaths get shorter and shorter. She's nearing the edge.

“Stop,” you command suddenly, your voice sharp.

She freezes, her breathing heavy. You know she’s on the edge, her body trembling with the effort of holding back. You stroke yourself harder, your own release building as you listen to her whimper, her fingers still pressed against her dripping wet pussy. The denial is killing her. You can hear it in the way her breath shakes, the way she lets out a soft, frustrated moan.
