Longer than you anticipated

You do not know who is the first person to run the show but the vibrator inside you comes to life, slowly at first. Obviously the person does not know how excited you are, otherwise they had every chance to win with their very first try. Instead, however, you manage to make yourself focus on the work in front of you, determined to minimise your embarrassment, if only to hide your enjoyment of it from your coworkers.

You manage to sideline the sensation in your nether regions for long enough to properly get into the final part of your report, so when the person in charge (you did not check the time so you are not fully sure if it is even still the same one) finally decides to increase the intensity, you find it surprisingly manageable. Keeping your muscles are relaxed as possible, you take deliberately slow and deep breaths, never stopping your typing, other than to check a fact or figure from your earlier notes.

To make your life even easier (although your body is screaming to let go and gyrate on the vibrator towards that relief now), the vibrator slows again when you feel you will not make it for much longer without allowing yourself to respond to the invasive toy. You hear someone whispers a muted curse, but whether it is related to your resilience or their work troubles you do not know.

You are approaching (as far as you can approximate at least) the half-way mark and your focus starts to wear off, both from the fact your work is done and from sheer tiredness. This is when the control clearly changes hands again... And you know you are in for it. The person knows too well what they are doing, keeping the speed high, but making subtle changes in rhythm that make it impossible to settle yourself and get used to it. Still, you do your best to keep your mind elsewhere, even as your hips begin to respond and the first soft moan escapes your lips... But it is futile.

The small hope you harboured of hiding your orgasm is equally futile, as when it comes, what feels like mere seconds later after your wall of resistance began to crumble, it is audible and clear. You manage to be quieter than you normally are, but to you further humiliation, you fail at that too. The vibrator goes quiet as you still squeeze and hump it, red-faced, out of breath and very much defeated.
