You're powerless to stop her.

You whimper through the fabric of the panties in your mouth as she reaches up with both hands and clutches your cock between her fingers. Instantly she starts jerking you off hard, her hands deftly pumping up and down while she sucks your balls. Your pre-cum lets her palms glide up and down with silky smoothness, coating your cock with a sheen of fluid. Within ten seconds you start blowing the hardest and most forceful orgasm you've ever felt, your ass jerking up off your office chair as you ejaculate a huge jet of cum straight up into the air. It splatters down on top of you, staining your suit, as your hips twitch and jerk while Gemma sucks and strokes away. Only seconds after your orgasm subsides are you hit with another one, raining another fountain of cum all over yourself, Gemma, and your desk yet again.

You are convulsing uncontrollably in your chair by this point. You've never felt such excruciating pleasure as Gemma works every surface of your balls and shaft. Tears roll down your face and you scream as much as you can through your makeshift gag as she runs the palms of her hands all over your sensitive head, lubing up your cock with the hot, thick cum which clings to the tip. A third orgasm hits you... and then a fourth... and then a fifth all the while her lips never leave your sack, and her hands work non-stop up and down your shaft. You've never cum so fast, so hard, and so often, ever before in your entire life.

Every muscle in your body hurts, and it feels like spikes are stabbing into your brain as you cum over and over again, each one harder than the last. By the time you reach your final orgasm, you shoot so hard that your ejaculation hits the ceiling, and your last blurry vision before you blackout is a thick rope of cum dangling down from above...
