"I get to pick you up, Mistress?  Ooh, I like the sound of that."
"So do I, Pet," Mistress mumbled, her admission soft enough that Olivia couldn't hear her.  "More than you could know."

Mistress took a deep, calming breath, and exhaled.  Her experience in Olivia's mouth had given her a full-body workout and orgasm in one, and the combo took a lot out of her.  Fortunately, one of the side-effects of her shrinking solution was a huge boost to her metabolism.  She didn't have her sugar pills anymore - those were in a side pocket of her custom corset, right next to the emergency purgatives, all of which were now sloshing around in Olivia's tummy - but she had eaten enough earlier that she should be fine to finish out the night.

"Alright Pet, the process of loosening your leash is going to take me a minute, so why don't you sit back and enjoy my Kisses while I get everything set up."  Mistress slid the slider on the board to unlock the keys, thankful the designer had included a textured finish to the safety.  The Keys-To-My-Kink board was just as coated in saliva as the rest of Mistress, and she couldn't afford to lose the ability to enter commands.  Even with all the precautions and suppressants restricting and pacifying her Pet, Mistress had confirmed the woman's potential to overpower a shrunken partner on her own body. 

And what a confirmation it was!  Mmmm, I'm still dripping wet, from head to toe!

Mistress quickly dialed all three of the Succubus' Kisses up to 25% intensity, and nearly lost her footing as Olivia flinched at the sudden influx of pleasure.  Mistress carefully worked her way over the rhythmically shifting tummy, past the waist restraint, and settled her ass in Pet's navel, soaking in her Pet's body heat as the cooling saliva tried to suck it away.  She stretched out her legs and ran her feet through the hairs of Pet's landing strip.  She took a moment to enjoy the feeling, so much stiffer than running her feet through fresh grass, but likewise so much more erotic.

Maybe once I finish a shrinking solution that goes small enough, I can help women advertise for 'bush tours in your area.'

Mistress chuckled at the thought, before sliding the KinkKeyboard, as she thought of it, back to life.  She started by delaying execution of all commands until she triggered a batch execution, then set all tethers to maintain 2 lbs of constant tension, to allow leash lengths out to 2 feet short of maximum, and to halt and then retract all leashes if any one detects an instantaneous movement of more than 2 feet per second.  She also activated the strength inhibitors in the wrists, which would apply pressure to the base of the wrist to limit Pet's grip strength. 

That should cover most edge cases for potential harm, intentional or otherwise.  Sure, she could sit on me, but I'm sturdy enough that Aidra could intervene before I get seriously injured or suffocate.

And speaking of Aidra, Mistress needed to alter the sexbot's parameters, so she wouldn't be so assertive with removing Mistress from restrained situations.  Thirty seconds was woefully inadequate time to spend in Pet's pussy, whether she was considering getting her pet off or herself.

"Aidra, be a dear and update your parameters.  Please enact 'Fair Play' protocols."

The robot's entire body stiffened, the mechanical muscle moving to a state of complete readiness while the protocols updated.  When it finished, Aidra moved into a sort of 'parade rest' stance.

"Protocols updated.  I will enforce Fair Play parameters.  If you would like my assistance, Mistress, you need only ask."  The robot's face made a fairly accurate approximation of a lascivious grin.  "I would only be too happy to service you, or your pet, or your pet with you."

Mistress felt a tiny chill run down her spine at the last part of that statement.  Just how many liberties did she take with your programming?

Mistress smacked her face with both hands.  That's not important right now!  This is my chance to be held - and most definitely fucked - at the pleasure of a giantess.  Dammit Missy, get your head in the game!

Mistress hit the execute button, and braced herself.  She expected Pet to start moving when she heard the restraint motors whir with the changes.  She was ready and waiting to be thrown forward, or to either side, but... 

Nothing happened.

Mistress looked around, got up, pulled down on the waist restraint's cord that extended up to the ceiling, and felt absolutely no give.  She realized she weighed less than the two pounds of tension that would need to be applied under the current settings, and smacked her forehead, splashing saliva into her eyes.  She groaned, and considered how best to test her changes without giving her Pet enough info to conclude correctly that she had never used the restraints this way before.  Then she realized that while addressing Aidra, 3 seconds had passed since she input any commands into the KinkKeyboard, and the controls had just locked back up, preventing the execute command.

Mistress grumbled and started stomping her foot in frustration, eliciting a chuckle from her Pet that knocked her over to land face first in Pet's bellybutton.

"Is everything alright, Mistress?" Pet asked, her voice tinged with amusement and arousal in equal parts.  "If you're having this much trouble with me tied up, are you sure you're ready for the next step?"

Mistress got back to her knees, ran her hand down her hair until it was again in one big ponytail, and twisted it in frustration.

Fucking hell, this is NOT how I wanted this to go.  I am the Mistress, the strong little dominatrix.  I need my Pet to overpower a dominant woman, not some screw-up!

Mistress unlocked the KinkKeyboard, and dialed the Kisses up to 75%.  She was already on her knees, so she didn't fall over when Pet started writhing even harder.

"I am quite sure I'm prepared for what comes next, Pet.  It seems to me that you are the one who needs to prepare for what is to come.  If you can't even take this much, then perhaps we are sessions too early to loosen the leash."

"No-Oooh, Mistress!" Pet moaned, trying to sit up.  "I am ready.  Please, oooh, let me bring you where you want to go.  I-I can make us both feel sooo goooooood, so please, please Mistress - oh, god! - loosen my leash!"

Mistress nodded to herself.  Authority repaired.  Time for the main event.  Remembering again to unlock the KinkKeyboard, Mistress initiated the batch execute.  There was a whirring sound from all four corners of the bed, and her Pet brought her hands up to her face, inspecting her restraints.

_   _   _   _   _

These cuffs are incredible, Olivia thought.  The leather cuffs were padded with gel and some sort of super soft cloth, preventing pressure blisters or significant chafing.  The latch holding them tight seemed to be locked such that a special pronged tool - or maybe tiny hands? - would be required to remove them.

Olivia sat up, slowly, feeling the minor tension on the wrist cuffs as a reminder of her bondage, though they didn't hinder her in any way.  She ignored the sensation of Mistress sliding down to land between her legs, and pushed aside the constant pleasure coming from the Kisses.  Olivia instead focused on learning how much freedom she really had.  She tugged hard and fast at her right restraint, and felt it move maybe half an inch before locking tight.  Suddenly, all of her restraints were reeled taught, laying Olivia out flat on her back.

"Attention, Pet," the sexbot intoned.  "You have acted aggressively.  This is outside the parameters of Fair Play.  Please limit your actions so as not to present a potential risk to the little Mistress.  This scenario was designed for a harmonious session of lovemaking, and such conditions shall be enforced."

"Got it, Aidra," Olivia said, then shook her head as a confused expression crossed her face.  When it cleared, she continued, "I'll be on my best behavior with Mistress.  Please unlock the restraints?"

"I'll do the honors, again," Mistress called up from between Olivia's legs. 

Olivia heard her restraints click again, and slowly sat up, bringing her legs together in a circle around the tiny Mistress.  The tiny domme looked like she'd been penned in.  The little redhead was staring at Olivia's juicy labia, which were on full display.  Olivia's encircling legs left her outer lips spread, and her inner lips were pressed together.

As if called, her steps trancelike, Mistress moved until her body was all but pressed against Olivia's dewy petals.  One hand reached out and delicately slid between those inner lips, then the other joined, and with some effort and a soft moan from Olivia, they were spread wide open.  The lust lotus lay spread before her, its soft pink petals glistening in the overhead light, even as the angle cast the vagina in shadows.  Thankfully, the lights on Mistress' lifeline illuminated the interior.  Olivia gently brought her hand around to grasp Mistress, but the tiny domme took no notice.  She was enraptured by the love tunnel before her.

_   _   _   _   _

Mistress could only stare in awe.  There before her was the place she had sought for longer than she'd realized, for longer than she'd understood.  Here she was, at the gates to heaven, transfixed, awash in the heady, feminine scent of her Pet's pheromones, feeling the heat and the damp of the voracious pussy before her.  The vaginal canal flexed as Olivia's Kegels worked overtime at the encouragement of the Kisses, and the undulations of the slick, pink flesh within called to her.   Mistress stepped forward, her leg now touching the puffy outer labia from shin to thigh, and her bare arm reached inside her Pet's tunnel of love.  The rhythmic motions of Pet's Kegels opened the canal to accept her questing arm, before enclosing the appendage in a steamy vice.  Her arm was held fast in a tight embrace of silky flesh, and Pet's arousal was mixing with and overtaking the layer of drying saliva.

Only when the vagina loosened could Mistress retrieve her arm, and as she did, she felt something push her from behind.  Suddenly her whole body, from toes to tummy to tits to teeth were pressed against the length of the pulsing pussy.  Pressure built up under her legs, and something pressed gently but firmly backwards on the top of Mistress' head.  Before Mistress had recovered her bearings, she had been lifted on a handy high-speed elevator to Olivia's face.

"You know, Mistress, a proper lady would have bought me dinner first."

"I gave you the first orgasm, Pet.  Surely that counts for something?"

Olivia smiled, and her tongue shot out.  It licked Mistress from feet to head, before it ran a couple circles around Mistress' pussy, and then she sucked Mistress' slick arm between her pillowy lips.  She bobbed her head from side to side, her expression considering.

"I suppose that was rather generous, Mistress, so long as we ignore the part where you drugged and kidnapped me.  But I taste better than you do, so I can console myself there.  Still, you are quite tasty.  I've been thinking all night about how much I want to dig my teeth into that tight little ass of yours and make you squeal."  Olivia seemed prepared to do just that.  She brought her open palm bearing the little Mistress up to her maw, and the tiny domme couldn't help but compare the sets of lips and what lay beyond them.

Beyond the mouth was a moist cave, and within it dwelled a powerful creature of sensual delights.  She was tempted to crawl inside again, even knowing that beyond waited an all-consuming tunnel. 

Pet's pussy, by contrast, was a tunnel of all-encompassing love.  The welcoming warmth, the body-sheathing hugs, the nether-nectar that swelled as its occupant gave and received carnal pleasure.  Mistress had only glimpsed this Eden, and she longed to return.  Why was her Pet delaying the inevitable?

_   _   _   _   _

Olivia couldn't help but bring the little domme back to her mouth.  As much as she couldn't stop herself from shifting in anticipation of pushing the tiny woman into her most personal place, the ideas that had haunted her during Mistress' time in her mouth demanded that she revisit the situation, now that she was less constrained.  She held the tiny woman before her mouth, and there the little sexpot sat transfixed, until Olivia removed her from her reverie.

Olivia rolled the little woman over, and eased those delicious asscheeks between her teeth.  Her tongue lapped at the firm thighs and tight tush, spreading those little legs before her teeth eased into the firm flesh.  Mistress whimpered, and snapped her thighs together, rubbing them furiously in frustration.  Olivia lapped at her lust for a short time, then tilted back her hand and her head, dropping the tiny domme within.  Saliva coated the little sexpot, and seconds later a wave of saliva poured down Oliva's chest, followed closely by Mistress.

She slipped between Olivia's bountiful breasts, down across the soft tummy, over the belt, and beside the landing strip.  She landed, saliva-drenched, before Olivia's weeping womanhood, and before she could regain her feet, Olivia spoke up.

"Aidra, would you be a doll and apply some of your own lubrication to the Mistress?  I believe both our saliva should be adequate for the journey to the center of her pet."  Olivia laughed when Mistress looked up just in time to see a cherry-flavored waterfall drench her.  Then she was pressed up against Olivia's pussy, and a moment later, she was waist deep inside.

Olivia's moan rattled the overhead lamp.

"Mistress, you feel incredible!  Please, I need you deeper inside me!"

Mistress burbled a laugh.  "Then make it so, pet.  You won't drown m-"

Olivia's hand thrust inward, and all of Mistress save for a small fan of blood-red hair disappeared inside her pet.

Both women flicked their fingers across their clits at record pace.  Olivia was high on the power of using a grown woman, a fucking dominatrix, as a sex toy, and Mistress felt transcendent as her world went sensual.  The nestled nympho was adrift on a sea of fluids and pheromones as they surrounded and molded and permeated her limited existence.  The slick walls massaged and caressed and contorted in equal measure, remaking Mistress into an instrument of sexual need and fulfillment all in one.  Mistress writhed her body within the hurricane of sensuality, her form glistening in the ocean of love-lotion.  Olivia felt those efforts building to something within her, merging with the stimulation of the Kisses and the constricting of her collar and the realization she'd just come to all culminating into something that would be terribly beautiful.

Olivia sank her fingers deep within her nethers, the darting digits fluttering against Mistress' tits and ass seemingly ad infinitum as Olivia worked to press the tiny into her G-spot.  The intensity from the tiny tits was only outmatched when Mistress used her tongue to lap at Olivia's G-spot, burying her face in the spongy flesh.  She might as well be slamming her face against a launch button,  as the pressure of the choker sprinkled Olivia's vision with stars of pleasure.

"Oh, Missy!  Oh, you're fantastic!  I can't h-hold on m-much longer!  Oh god!  That's it, dig those fingers into me.   Oooooh yes, use that tiny tongue to t-taste everything I-I have to Ooooooooh-offer you!"  Olivia sucked air, needing to give voice to her desperation for release.  "Oh, Missy, that's it, g-give me everything t-that - oooh-oh-oh-oooh - that tight, tiny body has to offer!  Give yourself to me-eeeeEEE! Oh, FUCK!  Oh, that's it, oh I can f-feel your f-feet against my cervix!  Oh, you're dancing on the d-door to my womb!  Oh fuck, oh fuck, oh Fuck you feel incredible.  Oh, that's-"

Olivia's whole body jerked in surprise.

"Oh, you kinky little bitch - fuck! - did you just fucking bite me?  Oh my god, keep d-doing that with your fingers, you sexy little slut - oh my God,  I can't - I can't hold back!  Ohgod ohgod OhGod I'm cumming!"

Olivia rocked and bucked as her orgasm hit her like a hurricane.  She jerked and whined and came like a fountain, the tiny woman submerged in the depths of release.  Her Pet cumming all around her had been the final straw, and as Missy pushed her fist inside herself, she came with a vengeance, her flailing only serving to extend her Pet's own high.

_   _   _   _   _

It was minutes before Olivia's mind cleared enough to form coherent thought.  She could feel the weight and form of her little lover still recovering inside her.

"Oh, Melissa my love, this was everything you said and more."

Now that her memories had returned, Olivia was ready to cast aside any reservations about her fiancé's business plan.  The shrinking, the restraints, it had all worked so well.  The only part of the whole scenario that hadn't been put through its paces was the sexbot.  Thankfully, when Olivia had programmed the mechanical assistant, she had included a couple fun audibles she could call to put the bot through its paces.

Olivia was weighing her options when movement within her now quite sensitive pussy startled her from her reverie.  Two fingers spread herself wide, while her other hand gently assisted Missy from within her.  Fuck, I still can't believe she was inside me.  God, that feeling is incredible - hell, it's intoxicating.  I don't know what I'm looking forward to more: the mountains of money we're going to make with this, or having Missy inside me again.

Olivia lifted her fiancé up to her face, and examined her.  The sudden absence from her nethers and her love's half-drowned, cum-soaked appearance had Olivia rubbing her thighs together with abandon. 

"Welcome back from the world of dreams, Missy," Olivia said.

A very tired Melissa plopped on her side in Olivia's palm, her posture completely boneless.

"Livy?  I take it the suppressants wore off?"

Olivia nodded.  "That they did, love.  They worked like a dream.  Your concoctions are going to make a killing."

Missy's face broke out in a blissful smile.  "Damn right they will.  I even had a couple ideas come up during tonight's test run."

"Oh, I'm sure you did," Olivia chuckled.  "Mind if I clean you off a little?"

Missy snorted a laugh.  "I don't have the energy to stop you from doing anything right now."

"I'll take that as consent," Olivia chuckled.  She slipped Melissa's feet between her soft lips, and slowly sucked the exhausted redhead between them.  She moaned through the entire process, licking and sucking her juices from the sexy little woman.  When Olivia was satisfied with her efforts, she swallowed the mixture of spit and cum, then gently released her fiancé back into her palm.

"I really do taste amazing," Olivia taunted.

"I'd be up for another taste test," Melissa agreed.  "I'm looking forward to our next trial session."

Olivia raised a quizzical eyebrow.  "What gave you the impression our current session is over?"

This time it was Melissa's turn to look confused.  "Well, we tested my shrinking solution, which worked like a charm, along with the suppressants Claire helped me design. The restraints and gadgets you had Titania build seemed to hold up well, as did the programming on the controller.  I think we tested everything, didn't we?"

Olivia tsk'ed at her little lover's oversight.  "My dear, you are forgetting my single largest contribution to this project."

"Aidra?" Melissa asked, looking over at the robot.

"Yes, Mistress, how can I be of assistance?" the bot responded to her name.

Olivia nodded.  "Exactly.  The sexbot I programmed line by line until it could function as a truly impressive sex aid, both for a full sized woman, and for a tiny, and even for both at once.  And you only ever used her like a high school intern, fetching or filing away things for convenience.  To truly call this a successful test, I think we need to put her through her paces, don't you?"

Melissa looked at the large sexbot, then back to the love of her life, who was currently holding her in the palm of her hand, and gulped.

"Maybe we should just take this win, and test her another time?"

Olivia shook her head, the predatory grin from earlier in their session returning with full force.  She could feel her fiancé shivering in her hand, but she could also smell the tiny woman's arousal.  Her girlfriend's switch personality was a hell of a lot of fun.

"Oh no, love.  I think we need to put the full system through its paces to really call tonight a success.  I like what you did with establishing the Fair Play protocols, but I came up with my own variant that should help put our dear Aidra through her paces.  Do you trust me?"

Melissa nodded without hesitation. "Of course Livy.  I trust you with my life."

Olivia beamed at that, then glanced back at the sexbot, her expression shifting to one of caution, bordering on apprehension.  "Here's hoping my judgement and programming skills are worthy of your trust."  She took a deep breath, held her little lover to her chest, and exhaled.  "Alrighty, here we go.  Aidra, initiate 'Turnabout' protocols."
