A neat little hands-free device.

She reaches above you and brings a large perspex cylinder down off one of the shelves. It's pretty bulky, over a foot long, and behind the clear plastic you can see a worrying array of electronics and motors packed into it. One end is clear and rounded like a bullet, the other is flat and padded with a tight-looking opening. It's clearly a serious piece of male sex hardware and you aren't in the least surprised as she squeezes lube into the hole and slips her fingers inside.

Your fingers are tingling and coming back to life again. Can you get enough of your motor skills back to stop her before she slips the hi-tech sheath onto your unruly, bucking manhood?

Of course you can't.

Both of you let out a little sigh as she carefully positions the tube and eases the purple head of your prick into its soft, firm opening. Sensation is returning all over your body, and just in time for you to feel the tight, wet pressure of the device dragging the skin of your prick back maddeningly. It already feels so good gripping you, and to your horror you find that you can see the tumescent tip of your cock through the clear plastic dome at the end of the machine. She moves a little cup-like attachment that you hadn't noticed before so that it covers your balls. The machine is now covering your entire genitalia, and a soft rubber lip all the way around the base seems to almost make an airtight seal against your flesh.

"It attaches with a vacuum," she mutters, and with the push of a button on a little remote she's holding you feel a powerful pressure on your lower abdomen. Your cock and balls are fine, but the whole assembly is stuck with suction onto your body. You've got to get it off!

"Hhhhngh!" you manage to say.

"You can probably guess what this is going to do to you," the lithe little tech-whiz says, working some controls at the base of the tube. "It's going to give you wank that's designed for maximum speed and satisfaction. You're the first person I've had the pleasure of trying this latest model out on, so y'know, pay attention to the sensations and tell me how they feel after if you don't mind."

"Hhhh... Fuck you," you manage to hiss, your body finally starting to reboot itself.

"No, I'm afraid you don't get to do that, mister," she smiles, almost apologetically. You don't even get to see my tits. Just sit here and cum like a good boy." She presses another button and with a whirr the soft, wet sheath inside the tube starts to jerk your massive, solid prick.
