It's a _very_ intense experience...

Lisa could still see a bit despite being reclined on the frame. She saw Elizabeth pick up what appeared to be a dildo with a wire running out of the back end... this wasn't unusual. The dildo was an unimaginative shade of gray, and most weirdly, it had several horizontal slits on it. At the base near the wire, there was a strange little metal ring.

"In order to do the personality transplant, the body needs to have a heightened level of electrical energy. The body produces electricity when it performs work... and to put it down on a level that could be understood by someone without an extensive scientific pedigree, this mechanical phallus implants data directly into the brain through the electrical energy in the body."

"Oh". Lisa said. "So why is this all necessary? I own dildos much bigger than that thing."

Elizabeth shook her head. "Because orgasm causes a loss of electrical energy. While the operation is taking place, you cannot be allowed to reach orgasm... and this 'dildo' as you call it is designed with just that in mind."

She squeezed it in one hand. The dildo lengthened and the gray rubber parts spread apart, revealing the metal inside.

"On pre-orgasm, your body will tense, squeezing the dildo and administering a mildly painful electrical shock that will bring the body down from an orgiastic state. Of course, it does not shut off. It will continue to stimulate you and prevent you from reaching orgasm at the same time."

Lisa started to say something, but Elizabeth interrupted.

"And this." She pointed to the metal ring at the bottom. "This fits over the clitoris, and it serves two purposes. One is to monitor heart rate and brainwave rate. It will thus know exactly how heavily to stimulate you to keep you at the highest level of arousal possible without doing any physical or mental damage. I modified it to do this after one of your mother's 'problem cases' ended up in a coma from overstimulation. The other, is that it fits over your unerect clitoris. Upon arousal, it will fit tightly enough to restrict blood flow, and thus, prevent clitoral orgasms."

"Wait. So, like, how long is this going to take?" Lisa looked worried.

"To be on the safe side, one half hour per person."

Two and a half hours...

"I can take it. Turn it on."

Elizabeth walked over to the computer and turned it on. The computer and dildo both began to hum.

"Oh, Lisa, the one last thing. To make sure that your body gets the oxygen you need, we need to hook up a breathing apparatus." Elizabeth reached up to the ceiling and pulled down what looked like a white gas mask. She squeezed it, and Lisa was shocked to see what looked like the top of a dildo come out of it.

Before she had time to protest, Elizabeth fitted the contraption over her head and tied it into place.

"Mmph!" Lisa yelled. But Elizabeth ignored her, and instead made another adjustment.

"MPPPH!!!"

The dildo expanded inside her mouth, filling it, pushing her tongue to the side and hitting the back of her throat. She then felt the rush of pure oxygen through the... thing.

"We also can't risk you biting your tongue and hurting yourself." Elizabeth said matter of factly.

***

Of course, everything works exactly as Elizabeth said it would.

As her body reacts to the dildo, her clit begins to swell. Trapped inside the metal loop, it becomes engorged and red, burning in arousal. The dildo continues to hum inside her, building her up. Lisa bites down ineffectually on the oxygen thing in her mouth. Her last thought that has nothing to do with sex is seeing her friends profiles on the computer, the same ones that her mother keeps on file...

Then, her chest starts heaving, her muscles twitch... and a sharp electric shock brings her back down, completely unsatisfied.

She can't thrust back against the dildo. She can't move her legs or arms. She can't even beg for mercy. She notices that her nipples have clamps on them - she hadn't even noticed Elizabeth apply them. Another shock shatters her thoughts. Her clit throbs. The dildo hold her right on the edge...

"...and we're done."

The dildo suddenly went dead inside her. She felt the ring come loose from her clit, and she was hit with an orgasm so hard that her ears rang and the frame she was locked on creaked as she tried to thrash around.

Elizabeth first unlocked her arms, and then her legs. The last thing she did was remove the oxygen mask.

"Well, Lisa, how do you feel?"
