Kirsty pulled the delicate nightie out of her big round belly, where it had been drying gently for the past hour.  She folded it carefully then set it neatly on top of an equally carefully folded tiger-striped bra and panty set.  “There you go.  Oh!  Right.  There you go, Zena.  Wow.  I’d forgotten.  Again.”

Kirsty unfolded the nightie to expose the tag, and the little loop of silver wire running through it.  She reached for the silver, forgot what she was doing, and put the nightie away again.

After cleaning for an hour, Kirsty returned to the bedroom.  “There was something important in here.  Now what was it?”  She retraced her steps to the nightie drawer, and when she opened it her eyes went wide.  “Right!  My nightie is also my sweetie.  And if I’m not careful about that silver, we’ll keep looping like this indefinitely.”

Kirsty spent the next half hour looking for the pair of pliers that she knew she had.  Eventually she gave up the hunt, and used two sets of tweezers instead.  She tucked the bit of silver back into the envelope in Zena’s purse, then started laughing.  The pliers were in there, too.

Kirsty turned back to the nightie, hoping that it had already started changing back to normal.  She hadn’t seen Zena in a few days, and now that she could remember her, she missed her sweetie.  Nothing happened.  She sat and watched for half an hour, her robotic torso giving her the ability to sit still indefinitely, and still nothing happened.

Kirsty tried very hard not to panic.  Had she left it on too long?   She was pretty sure it had been less than a week.  A quick check of her cell phone confirmed her recollection, she had a text from Zena only four days prior, all eager and excited to take her to the Blue Vixen.  Kirsty patted her mechanical torso, and rubbed a hand over the smooth chrome of her belly.  She’d gotten quite the change, alright.  She looked like she was nine months pregnant with a baby appliance.

Kirsty checked the Blue Vixen’s website.  Prominently displayed on its front page was a lunar calendar, and she sighed when she saw it.  The moon wasn’t going to rise...  She blinked at the display in confusion.  It didn’t rise at all?  How could that be?  When she clicked forward a day she saw why; it would not rise until shortly after midnight.  She pouted at the screen, then sighed.  No sweetie for hours and hours more.

Part of her argument with Zena had been over cleaning, so Kirsty decided the best way to distract herself until Zena’s return would be to continue cleaning.  Over the past few days she’d cleared up most of the long-running messes, taken out the recycling, and washed pretty much every scrap of fabric in the place except the curtains.  She poked at the curtains, wishing that she had a steam cleaner.  Something went ‘clunk’ in her belly, and when she opened the dryer door there was a steamer attachment sitting there.  The end of it looked rather like the belly-button “socket” just below her dryer door.  When she plugged it in, the steamer attachment whooshed to life.

Kirsty hummed happily to herself as she cleaned the curtains in room after room, finishing up in the bathroom and steaming not only the shower curtain but also the grout in the shower until it sparkled.  By then it was time for dinner, somewhat late for it in fact.  She still needed to eat, but only about half as much as before.

After dinner, Kirsty cleaned up the kitchen.  It didn’t take long, as she’d already scrubbed all of the surfaces over the past few days, and she only had to clean up the pan, plate and utensils she’d used.  She still kept cleaning, and did a quick sweep of the floor while she was at it.  Then she tucked the washcloth and dish towel into her breasts, so she could have another little load of laundry going.  She watched TV for an hour but paid more attention to the sloshing than the screen, and when her breasts pinged that they were done, she giggled and squirmed as she felt their contents slither down into her dryer-belly.  The soothing feeling of warmth from within made her sleepy, so she headed toward bed.

Instead of wearing the nightie as she had the past few nights, Kirsty laid it out in Zena’s half of the bed, brushed her fingertips over it lightly, then dozed off.

Kirsty woke to Zena’s kiss, and smiled.  “Oh!  You’re back.”

“And horny as hell.  Why didn’t you wear me tonight?  I remember the other nights, they were lovely.”

Kirsty blushed.  “And I needed to wash you afterward.  I didn’t want to accidentally be stuck in you when you changed back.”

Zena’s nose wrinkled in distaste.  “Ew.  Fair call.”  She kissed Kirsty again, then made it very clear that she had no objection whatsoever to Kirsty keeping her as a nightie for a few extra days.

After they were finally spent, Kirsty snuggled up beside her sweetie as they dozed off to sleep.  “You should be my nightie more often.  That was fantastic.”

Zena snorted.  “I can’t afford a week off every full moon.”

Kirsty nosed a little closer and kissed her cheek.  “Not for days, just... however long it’d take to rev you up like that.”

Zena smiled at her.  “Sounds nice.  Pity magic doesn’t work like that.  We’d have to go bug Donna all the time.”

“Ah well.”

In the morning, Kirsty was up well before Zena, and had her breakfast ready for her when she emerged from the bedroom, yawning.  “God, I slept like a log.  How are you so alert?”

Kirsty shrugged.  “Cyborgs don’t seem to need as much sleep.  Means more cleaning time, so it’s all good.”

Zena peered at her curiously.  “More cleaning time is... good?  Who are you and what have you done with Kirsty?”

Kirsty giggled.  “It’s just so easy like this.  And having something churning away inside me feels good.  Also... I got stuck in maidbot mode whenever I washed you because of the silver.  It feels like second nature to me now, there’s this happy glow of satisfaction for a job well done.”

“So I should put some silver on you so that you’ll clean up the place?”  Zena looked around, blinking owlishly.  “Wait.  Where’s all the mess?”

“Gone.  I spent the last couple days zoning out in robot maid mode.  Everything that can be cleaned has been.  Often more than once.”

Zena blinked at her again.  “But... you hated cleaning.  Whined whenever I asked you to.”

“Because I was tired!” exclaimed Kirsty.  “Working all day, worrying myself sick over all your rehearsals of that idiotic presentation...”

“Hey, that presentation got me the new position and the raise that meant you could quit your old job.  So... do I pay you to be my live-in maid, now?”

Kirsty giggled.  “I’d rather be your robot maid that serves you because you’re my master.”

Zena boggled at that, and covered her confusion by sipping her coffee and eating part of her breakfast.  Kirsty watched, then got herself some coffee when Zena gestured for her to join her.  Zena noticed that as Kirsty sat, one hand drifted to her rotund belly, patting it softly.

“I don’t want to be your master,” said Zena at last.  “We’re going to get married, we should be equals.”

Kirsty nodded.  “I guess,” she admitted grudgingly.

Zena raised an eyebrow.  “You’d prefer I say silly things like, ‘Kirsty, enter robot maid mode and clean the living room’?”

Kirsty stood up abruptly, and bowed to Zena.  “Yes, mistress.”

Zena shook her head, chuckling good-naturedly at how far Kirsty went for her little games.  She finished her breakfast, showered, and then returned to the bedroom.  Kirsty was standing there, at attention.

“Uh, Kirsty?  Are you okay?”

Kirsty didn’t respond in any way.

“Wow, you’re serious about playing robot maid.”

“Yes mistress?”

Zena rolled her eyes.  “Robot maid, please enter Kirsty mode.”

Kirsty’s pose suddenly relaxed.  “Holy crap.”

“What?  I get you were playing along...”  Zena’s eyes widened as Kirsty shook her head.  “You weren’t?”

“Not... exactly?  I kinda went along at first, then I couldn’t stop.  Ooh, that might have been my fault.”

Zena raised an eyebrow.  “Your fault that you obeyed my orders?”

“Um, that I kind of wished you had override command over me.  Something clicked then, and... I couldn’t un-do it.  My body just went and did things.”

“Well, un-do that now!” barked Zena.  “I don’t want you to be my slave.”

Kirsty batted her eyelashes at Zena.  “Are you sure about that?  Wouldn’t you like to be able to order me to massage your feet, or wear your favourite sexy outfit?”

Zena smirked.  “I can just ask you to do those things.”

“Please?” asked Kirsty with a big smile.

Zena smiled back at her.  “Fine.  Kirsty, enter robot maid mode.”

Kirsty’s pose stiffened once more.

“Robot maid, status report.”

Kirsty rattled off a variety of information in a monotone, mostly various biological and mechanical system diagnostics.  Zena ordered her to stop.  “What can you tell me about your robot maid override mode?”

“Operator Zena is the only person on the override mode authorization list.”

“Wait, so Kirsty can’t take me off the override list?”

“Correct,” intoned Kirsty.

“Oops.  What would happen if I took myself off the override list?”

“Invalid state.  There must always be someone on the override list.”

Zena nodded slowly.  “Clever of Donna.  Okay... can I put Kirsty on the override list?”

“Yes.  Do you wish to do so?”

Zena was about to say yes, but suddenly she stopped.  Kirsty’s eyes shone with something beyond robotic zeal.  “No.  Return to Kirsty mode.”

Kirsty took a ragged breath.  “I guess I really am your robot maid.”

“Does that worry you?” asked Zena softly.

Kirsty giggled and shook her head.  “That you have control?  No.  That’s awesome.”

“Why?”  Zena sat on the edge of the bed, and patted the spot beside her.

Kirsty perched beside Zena, one hand drifting again to her rotund dryer belly.  “I like this role.  Being your proper housewife.  It’s a little scary to be so dependent on you, and give up my independence.  I feel like ‘robot maid’ is a more comfortable role than roomie who’s sponging off of you.”

Zena looked shocked.  “I would never think of you like that!  I love you.  Robot maid and all.”

Kirsty giggled.  “Oooh.  You could order me to make love to you.”

Zena hugged her and nuzzled that little spot at the hollow of Kirsty’s neck that made her go all shuddery.  Kirsty’s mechanical body buzzed softly as she shuddered right on cue.  “Ooooh, right.  No orders needed for that.”

They spent the rest of the day exploring the limits of Kirsty’s programming.  It wasn’t quite as strict as she’d thought.  She could fight against its attempts to move her around, though doing so made her terribly clumsy and it was simpler just to go with the flow.  If she didn’t ‘help’, the robot was still somewhat clumsy, it seemed to need her fine control as well as her ability to judge which objects were which, and how to deal with them.  Zena tried ordering her to pick socks out of a basket of fresh laundry and match them.  Kirsty’s programming could only force her to stand in front of the basket, but it would do so until she’d picked out and paired all the socks she could see.

Every time Zena ordered the robot maid back to Kirsty mode, she’d get a big hug and kiss to reinforce that Kirsty was very happy being her plaything.

That night, Zena dressed up in the scaly Sheri outfit, and offered the stripy Jasmine outfit to Kirsty without making it an order.  Kirsty wheedled unsuccessfully, then did her best to make a show of slipping into the stretchy outfit.  She danced when she was done.  “Like what you see?”

Zena purred happily.  “Yes indeed.  So much that I will reward you with what you want most.”

Kirsty’s eyes shone as she waited.

“Kirsty, enter robot maid mode.  Robot maid, make sweet love to me.”

Kirsty’s robot maid persona had little idea how to proceed, but Kirsty’s skill and exuberance more than made up for that lack.  She followed Zena’s orders to the letter, slowing or speeding up as requested, suckling harder or softer.  Kirsty’s strength did not falter in the slightest as Zena’s back arched under her ministrations, and Zena thrashed through orgasm after orgasm.

Eventually, Zena whimpered in exhaustion, “robot maid, stop.”

Kirsty stopped, then stood at attention at the foot of the bed.  Zena’s juices glittered unheeded on her face and hands.

That was where she stood until Zena woke.

Zena patted the bed beside her, frowning at the lack of a warm spot.  She yawned and sat up, the squealed in surprise to see Kirsty still standing watch over her.  “Oh, Kirsty!  I forgot about you, I’m so sorry.  Robot maid, enter Kirsty mode.”

Kirsty relaxed, then toppled into the bed.  Zena pulled her up beside her, cuddling her close and repeating apology after apology.

Kirsty shook her head in confusion.  “I... whuh?”  It took two more repetitions before she was awake enough to press her fingers to Zena’s lips.  “Stop.”

Zena’s brow furrowed in confusion, but she stopped.

“Did you enjoy yourself last night?”

Zena nodded silently, Kirsty’s finger still brushing her lips.

“I did too.  Now maybe you owe me an orgrasm or three...”

“Or ten,” interrupted Zena.  Kirsty shushed her again.

“So we’ll do this the right way.  First, we both need showers.  Then breakfast.  Then you will be my sex slave until such time as you feel you have repaid your debt.”

“Your what?” cried Zena.

“Obedient sex robot, then?” asked Kirsty with a mischievous sparkle to her eyes.

Zena chuckled softly.  “Oh, I get it.  Turnabout is fair play.  I don’t have a magical control circuit making me obedient, but...  I guess I can try.”

Zena proved to be a fractious and distractible ‘robot’, but by the end of the next day she felt she had expiated her debt.  She crawled up the bed to cuddle up beside Kirsty.  “There.  Even?”

Kirsty giggled delightfully.  “Oh, I’m sure I’m back in your debt, now.  Whatever shall I do?”

“Why are you so keen on this?” laughed Zena as she flopped to her back.  “Am I such a good mistress?”

Kirsty shook her head.  “No, you’re a terrible mistress.”

“What?”

“You barely give any orders at all.  That’s the point, silly!”

Zena craned her neck to the side to look into Kirsty’s eyes.  “I was trying to go easy on you.”

“It’s way more fun to be doing things because you ordered me to, than to do them on my own.  Especially cleaning.  When you go to work Monday, can you leave me in robot maid mode?”

Zena flopped back again, and studied the ceiling as if some great revelation was to be found there.  “I would rather not.  What if there was a fire and you had to evacuate?”

Kirsty sighed mournfully.  “Fine.  I’ll just have to pass the time by cleaning whatever I can find.  I’m sure Jasmine and Sheri would appreciate an extra wash cycle or five.”

“There’s the spirit,” chuckled Zena.  “Pity I can’t put you on a lower priority access list, that only lets you leave robot mode in emergencies.  Wait, are there tiers of access?”

“Robot me, robot me!” cheered Kirsty.

Zena rolled her eyes and did just that.  A few questions later she had a somewhat better idea of Kirsty’s priority controls, and had added Kirsty to one that only controlled entering and leaving robot mode.  When she put Kirsty back to normal mode, Kirsty pouted at her.  “But I can leave robot mode any time I want, now...”

“Don’t worry.  I’ll take you off the access list when you want to be stuck.”

“But...”

“Kirsty, it’s getting very late, and I’ll have to get up early on Monday.  Go to sleep.”

“Make me?” asked Kirsty sweetly.

Zena sighed softly.  “Kirsty, enter robot maid mode.  Robot maid, enter sleep mode for the next seven hours.”

“Shutting down.”

Zena giggled.  “Nice.  This might just work after all.”
