Not quite.

You always enjoy giving head, and even though the Sub-Commander doesn't puts more value on efficiency than skill you try to do a good job of it. However, this morning you've barely gotten your mouth halfway down her thick shaft before she nudges you with her foot, and when you look up at her to see what she wants she gestures for you to come up again.

While she continues to speak on the phone you crawl out from under her desk, discretely wiping your mouth. When she points to her desk you quickly turn and bend over, pulling your minimal skirt up to bare your ass. You spread your legs and use your hands to open yourself up to her as she rises from her seat and stands behind you, guiding the tip of her cock to your slit.

It's a good thing tasting her precum and sucking her cock has made you wet, because she takes a firm grip on your hips and pushes herself all the way inside you with one hard, smooth thrust. You gasp and whimper when she fills you so suddenly, but she takes no heed. Still making the occasional comment on her conference call, she places on hand on your shoulder to pull you against her as she begins to fuck you, hard and efficient as in everything. You hold on to the edge of her desk to steady yourself as she hammers into you again and again, filling your pussy with her long, thick cock over and over.

It only takes a few minutes before you cum, spasming around the Sub-Commander's still thrusting cock. She pauses to give your ass a little squeeze, the closest she ever comes to giving encouragement. Your body is still shivering from the intense climax when she begins to fuck you again, thrusting even harder now, possibly excited by how easily you came. Your head is swimming from the intensity of the sensation and you hear yourself cry out with every thrust.

Then she increases her pace further, her hand like a vise on your shoulder as she grunts, hilting herself inside you with deep, irregular thrusts as she cums, flooding you with her sperm. You feel the mixture of your fluids begin to leak out of you and slowly run down your legs as she makes a few more thrusts, the last spurts of her cum shooting into you. She pauses for a moment to draw a shuddering breath, then pulls out.

Your legs are numb as you try to stand, steadying yourself on her desk with one hand as you wobble. The smell of her cum is intoxicating, and when she sits back down and gestures for you to suck her again you eagerly obey. You lick her slowly softening cock clean from the sticky mixture of her sperm and your juices, squeezing out the last few drops of cum onto your tongue.

Once she is satisfied that you have done your job she dismisses you with a curt gesture. You rise unsteadily to your feet and pull your skirt back down, then curtsy and go back to your station.
