From Jenny to Mei Ch. 10

This is part 10... you probably want to start with part 1.

Thanks to DWS1973 for the editing!

*****

Mei was happier than she had ever been before in her life, and it was all thanks to her blackmailer, Philip. The transformation from Jenny to Mei Chun wasn't complete by any measure but at least she was now persistently nice. It still took effort, especially first thing in the morning, but she was definitely getting the hang of it. She began to look outside herself, seeing those around her as real people and asked nearly everyone she spoke to their names which made it easier to recognize their value. When she wavered she would picture their parents holding them as babies, whispering their names to them; it seemed to help.

She now noticed kids not as annoyances to avoid but as little people, dear and cute, or tired and hungry when they weren't well behaved.

She started dressing with an eye to the photo she planned to send Markéta everyday. Today it was a pair of pants that were tight around her firm bottom and hung loose to the cuffs, they were super comfortable and cost three hundred dollars. She paired it with silk blouse with paisley patterned embroidery. The pearls adorned her neck, of course.

Even though they had only met once for a few hours she felt a profound connection with the older woman. There was an echo of her relationship with Philip too. She knew she was Karla's superior and Philip's outright possession. However, Markéta, perhaps because of her age, but more likely her manner, was the leader in their particular relationship, which was fine with her. Nothing would make her happier than to submit to her in bed as she had in all things sartorial.

She traded a few texts with her lovers and worked on her letter to Philip during lunch taken quietly in Dr. K's office.

Sandy, the girl who was to help put Mei's gift through a trial run, showed up at noon. She was with an ugly, squat, sinister looking, thug type standing a half step behind her at the street level door. The contrast between them could not have been greater. She was of Vietnamese heritage and good-looking, youthful, vivacious. She was waifish but still looked healthy in the way Asian girls could somehow get away with. She had something of the bewitching, winsome beauty that could make a woman dangerous. He, on the other hand, was a dirty looking Hispanic with gang tattoos and a Yankees cap and carried himself with false confidence and fabricated hostility.

"Hi. Welcome. Come in," he greeted them both politely. "Thanks for coming. I know it's kind of a different assignment than you're used to but it'll be a great help."

"Sure. Glad to help," she said with a high and bright voice in an attitude of helpful enthusiasm. She didn't quite bound up the stairs but she wasn't shy.

Philip stepped around her at the top of the stairs and inquired about something to drink as he walked to the kitchen. When he didn't hear a reply he turned around and saw her studying her surroundings. The guy, who smelled of an aggressive stupidity, surveyed his place, no doubt thinking how he could break in.

"Iced tea? A soda? Coffee?"

"I love the place," she said, then, "Oh, nothing for me, thanks."

The kid in his twenties wanted a beer, probably because that was what he thought he should have rather than what he preferred. Ignoring him, Philip set a coke and a water on the kitchen counter as they took stools. Between the two bottles he placed a plain white, business sized, envelope containing $400. Adjusting his cap, the thug took it, turned around and leafed through the bills.

"So this is what I need," Philip began, speaking to Sandy, "I've built this toy for my girlfriend and I need someone to get on and let me adjust it so I know it works well."

"What kind of toy?" the guy asked.

"It's a fuck machine but with some interesting features."

The thug looked as stupid as he was. Sandy just said, "Wow."

"I'd like you to get on and I'll move the mechanism slowly through the full range and then get your feedback. If it's all good we'll fire it up and give you a ride, ok?"

"Sure," she said, "I'm game. Where is it?"

"Over there," he said, pointing toward his workstation. Both of his visitors turned their heads to look. He saw her in profile for the first time and was reminded of the graceful and trim figure of a two-year-old quarter horse, then tough guy's phone rang and he answered in Spanish.

"Let me show you," Philip said as he led her over to the machine which looked part bench press and part machine tool.

"Wow," she said, "how does it work?"

He described its general function. "You see, these two down here do the heavy lifting and the straps there keep her thighs pressed down and those bind her ankles. Also the board at the back can be a back rest or put in these holes here to hold her forward and expose her back. It has straps too; they're not attached at the moment. Ever use a fuck machine?" he asked.

"Well, no, not exactly," she said with a giggle.

Philip looked at the walking tattoo display that was ambling over toward them, still on the phone, and then back to Sandy. He couldn't believe such a fine young woman would consider this thug worth dating.

"Oh, he's not my boyfriend," she said, seeing his look of politely disguised disgust.

"Anyway," he continued, "the mechanism here is what does the work. It's a half horsepower, two phase induction motor, to keep it quiet, of course. This eccentric wheel is kind of a cam, or flywheel, that pushes this drive shaft which is connected by this ball linkage to the main thrust rod attached through these two pillow block bearings, for stability and to reduce vibration. That's what drives the dildo and," he bent down and removed the phallus, "Inside I've designed this thrust collar and these spreading veins that open in the center a few centimeters to increase its girth. I considered an air bladder but went with this instead. This other, smaller motor works the anal dildo."

"Oh my god," she said looking intently at the workings under the bench. "So... she's strapped in here and gets fucked by both dildos at the same time?"

"Yes. Each are independent. And I've got an onboard controller that I can load pre-programmed patterns for everything. I'm thinking of syncing the speed control to Ravel's Boléro, which should be an interesting fifteen minutes."

"And what's this for?" She pointed to a box closer to the front with tubes running out forward.

"That's for the suction." She looked inquisitive and he said, "For the nipple suckers."

"Oh... I see."

The punk got off his phone, shaking his head and said, "I got to go. You ok here?" he asked her, clearly disappointed that he would miss the show. She nodded, "I'm fine."

"Mister," he said, "you've got one twisted mind. I like it. You make one of these for me?"

"Afraid not, this is a one-of-a-kind."

With a shrug and a smile, the 'escort's escort' left down the stairs with the envelope in his back pocket.

"Good," she said a few seconds after hearing the downstairs door close, "he's such a creep."

"You need him for protection?"

"Yeah, he's kind of my manager, does some screening and he's never far away. I just wish he wasn't such a prick."

"Freebies? Aren't there other options?"

She shrugged, "Yeah, I could get with an agency I guess, but I don't think he'd like it. He's threatened to beat me up before."

He didn't continue with this line of conversation, just patted the seat and said, "Let's get started."

Sandy peeled off and wiggled out of her tight jeans then laid them over the back of his work chair. Philip had admired their ability to hug her compact and toned ass. She removed her black g-string without ceremony, but gave him a look through the curtain of fine black hair as she did so. She sat on the machine's bench seat behind the hole through which the dildo would thrust.

"Got some lube?" she asked and reached through the hole to grip the rubber cock. "This is clean right?"

"Um... here hop back off and go wash 'em off in the sink, I'll get some lube."

They met back at the machine a few moments later. He replaced the thick dildo over the mechanical innards by turning it inside out and rolling it down over the intricate mechanical cock. He'd made it himself through a mold of his own cock, but twenty percent wider and longer. It had two soft nylon mesh reinforcements between three layers of different density latex. He was concerned about it slipping off but that's what tests were for. If it became a problem he'd simply screw clamp it down.

Sandy re-mounted and spread a generous amount of lube on her lips. "Can we try the main one first? I'm not a big fan of DP unless I'm really ready."

"Sure, good idea."

He lay on the floor and watched as she lifted her foot to the rest, not bothering to wrap her ankle in the restraining cuff. Looking up he saw her pretty, partially shaved pussy through the oblong hole in the seat. "You've got a lovely pussy, Sandy."

"Oh, thanks," she said as brightly as a JV cheerleader.

"Ready?" he asked, admiring the shining glint of lube on her lips.

The sight of a wet pussy caressed something deep within Philip. He had a profound appreciation for the beauty of a human vulva, and this one would, he was sure, take the blue ribbon in any competition.

"Ready," she answered with enthusiasm.

She scooted forward and he began the drive wheel turning by hand and remembered something. "Can you slide back for a moment, Sandy...? I want to check for depth." She slid back and he twisted it through its motion. She saw that it topped out close to her navel.

"That's too deep," she said, still bright and cheerful.

He adjusted the depth by twisting the thumbscrew where the thing attached to the thrusting arm and lowered it while the cam was at its apex. "How's that?"

"Yeah, let's start there," she said and scooted forward.

When she was in place, he pushed the wheel forward a quarter inch at a time and watched the light tanned bulb of the dildo slowly push her lips apart and enter her. He shivered at the sight.

"Mmmnnn, gently... that's a bit bigger than I'm used to."

"Too much?"

"Um, no. But I'm tiny down there anyway. Is your girl my size?"

"Well, I haven't inspected you in detail but she's pretty damn small."

"White girl?"

"No, she's Chinese." He kept turning the wheel watching the fake cock disappear into her.

"Ah, you like us Asian girls?"

"Yeah, I admit to having a special affection for girls..."

"Like...?"

"You're very lovely, Sandy, but frankly from this angle, almost any girl would look great."

"Ah, so you like to watch?"

"Have you ever met a man that didn't?"

"You know, I haven't been doing this job that long... only a couple months."

He wondered why she said this.

"Okay, that's top dead center, how does it feel?"

"Mmm, feels great, maybe a little deeper. Try say, half an inch or so maybe a bit more."

He loosened the thumbscrew again and twisted the shaft so that it penetrated her another three-quarters of an inch. "How's that?"

"Oh that's perfect."

"A nice full sensation?"

"Yeah, feels great."

"Ok, I'm going to rotate it to the bottom now. My concern here is that it doesn't pull all the way out but it should be about right."

He began to turn in the wheel slowly, withdrawing it from her until he was at bottom dead center. He could see that it was still about an inch inside of her.

"Is that good? Or do you like it to come out a little bit further?"

"No that's perfect, just right. I like it just right there."

"Good, well that's the basics and I only have you for an hour so let's turn it on and see what happens. Is the angle right? I could tilt it forward or backward a little bit. Is that comfortable the way you're sitting?"

She looked around at her legs and her knees and gripped the handles bolted two inches up from the bench. She gave a little bounce, feeling the thing move within her. She looked at him and said, "Yeah that's fine. This is so much fun!"

"Ok, so I'm going to turn it on the lowest setting and just tell me how you feel. I don't have the interface to my computer finished yet or a remote so I'll have to manually turn the speed knob."

Still lying on the floor looking up at her pussy being penetrated by the homemade analogue of his cock, he twisted the potentiometer that controlled the contraption's speed. There was a quiet hum as the motor engaged but didn't yet have enough power to move. He turned the knob slightly more and it began a very slow glide upward. He was pleased with the smooth action.

Sandy absentmindedly ran a hand over a breast and squeezed as she looked down and saw the dildo slowly enter her.

As it gently gathered speed it occurred to him that he should put a buffering circuit between the potentiometer and the motor lest it get accidentally turned too quickly and injure someone. He twisted the dial another notch and the connecting rod began its motion around the outside of the cam. He decided on an oblong drive disk, with lots of adjustment holes rather than a circular one to give a bit of a pause at the top and bottom of the stroke. He would experiment with different shape discs in the months ahead but this would do for now.

He stared in utter fascination as the dildo penetrated, paused just slightly, and slid back out of her. For a minute he contemplated this view and noted how much it felt like meditation. "How's that?" he asked.

"Wow, it's really good. It feels so real. Like some guy who knows what he's doing is going nice and slow."

"Do you like the dildo?"

"Yeah it's great, better than mine. Too bad it doesn't vibrate. It looks so real. It even has a curve in it."

"Oh, it vibrates and it should look real. It's based on a cast of my own."

"Oh wow!" She liked the idea of his inside her.

"Yeah, a bigger version to be sure but it's much more personal than just a cock you buy at the store."

"That's so sweet. She's going to love it. I like the way the head scrapes against my g-spot on the way down."

"Tell me when you want it faster."

"Yeah, now would be great."

Still watching from below, thoroughly absorbed by the motion and the expanding and contracting of her lips around the thing, he twisted the knob an eighth of a turn and saw her lift a little bit as the speed increased, then settle back down. There was also a switch mounted under the seat which turned on a smaller high speed motor. It was mounted directly below the hollow main thrusting arm and connected to a shaft that ran inside it to a bearing tack welded at the top of the dildo core. A two inch long aluminum weight, drilled off center, was threaded over the rod within the head of the dildo. It wasn't elegant but he thought it vibrated it rather well.

The machine made a sort of clickity-clack, clickity-clack sound when moving that wasn't unpleasant but belied an imperfect design. He'd review it later and perhaps change the linkages.

"Oh God, it does vibrate?" she said, her breath catching in her throat.

"Yeah, how do you like it?"

"Wow..." She gasped at the whirring vibrations deep inside, "it's fantastic. So strong! A little faster if you could."

"Sure," he twisted just a little bit more, wanting to take his time and gather all the research data he could.

"How is it?"

"It's... oh god, it's great!" she giggled and smiled as bright as new daffodil.

"Can you come like this?"

"You're about to see for yourself I think. Can you go little bit faster?"

"Not yet. I have to say it looks spectacular going inside of you. This is about thirty revolutions a minute or so. Is this about the speed that would cause you frustration, like you can't come?"

"Yeah, if it went on like this for ten or twenty minutes I'd go insane."

"Great."

"Is that the idea?"

"Sort of, I'm hoping to strap her down to this for an hour."

"Poor girl." She said it with a smile, intending to be ironic.

"Are you ready for the expanding?"

"Oh that's right, you said that there was more. But does it get bigger and smaller or just bigger."

"Well, I guess I can make it cycle but I was thinking that it would be better just if it got bigger."

"Sure, why don't you start with it bigger and then maybe test cycling it a bit."

"You want some water or anything, Sandy? I see a bit of sweat on your stomach."

"No, I'm good, thanks."

With yet another control he caused a flange just below the dildo mounting point to twist. This pushed up on the thrust collar which forced apart the leaves that made up the center of the dildo, expanding it. He got so caught up in the design feature that he never really considered if it would be comfortable or arousing.

Sandy was looking down the whole time now, watching this cock give her a really good workout. And then she saw it thicken before her eyes and felt the fullness grow within her. "Holy shit!" she said. "Wow. That's amazing."

"Not too tight right? It only expands by about twenty percent but still that should be noticeable."

"Wow, no. That's okay. Any more than this would split me. But wow, it feels awesome, more friction." She was breathing heavily now, noticeably aroused.

"Can you come?"

"Um, yeah... whether I want to or not."

"Want to?"

"Yeah please, but..."

"Yeah? Want some nipple clamps?"

"No, just turn it faster and get up here and kiss me."

He turned it up to about sixty RPM, one complete thrust in and out per second, and got up and sat before her on the machine. He looked at her; she was very beautiful like this. 'Innocent,' was the word that came to mind, 'young, innocent and simply beautiful,' he thought. Her hands were between her thighs gripping the hole through which the phallus thrust, pushing against the bench, lifting her bottom slightly and pressing her gently bouncing smallish breasts together, nipples boastfully erect. She had a glazed look in her eyes that showed she was seconds away from a really satisfying orgasm.

"You're beautiful, Sandy."

"Kiss me. It'll make me come right away."

He put both of his hands tenderly on either side of her face, leaned in and kissed her firmly. He intuited that she wanted the feeling of intimate contact so he didn't slide his tongue into her mouth or kiss her with haste.

The trigger for most of Sandy's orgasms was the sensation of just this kind of intimacy. She breathed quickly through her nostrils, inhaling his masculine aroma. "Mmm...Mmm," she hummed against his mouth. Her lips parted for just a second to let out two 'Oh... ohhh's. And true to her word, hopping gently on the dildo, she immediately started to orgasm. He could feel her tense as she sucked on his lower lip. She whined like a Geiger counter being swung over a radium sample, and then pushed down with all her weight, brought her arms around his neck and pulled hard.

"Oh god," she huffed. "Oh god... goddammit!" She convulsed and shuddered, panted and groaned directly into his ear a long lowing, like a hoofed animal giving birth. She quieted for a moment then disengaged from him and sprung up. She looked down at the still pumping penis jutting through the hole in the seat.

"Jesus... wow, that... wow..."

"Like it?"

She hopped up and down, which jiggled her breasts delightfully. "...wow. That thing is great. Holy shit! You going to sell 'em?"

"Nope, it's a one off," he repeated, "just for my girl."

"She's so lucky," she said, looking in his eyes, still astounded but giggling now.

"Need to take a break?"

"Yeah... just a minute or two." She stretched on her toes, "Let me walk around a bit." She walked over to the counter and drank the water. "What... what that took like five minutes?"

"Yeah, about that long." Philip added the anal dildo, "Want the full treatment?"
