Wow! Look forward to finding out the girls reaction. Even more so when they discover the new girl is really a boy. Sounds like Bobby is going to have plenty of attention and probably enjoy every minute of it.

Chapter 161.

Tuesday morning, seven o’clock.  Bright sunshine, but an autumnal chill in the air.  Nicole stopped the car in Clarissa’s driveway and opened the door.
“Okay, I’m going to have a quick word with Clarissa.  You can take your things in.  I don’t know if Mellie’s awake yet – oh, yes, there she is now.  She looks happy to see you, Bobby.  Go on – pop out and say hello.  I’ll get your stuff out of the back for you.”
Clarissa and MĂ©lisande had appeared at the top of the front steps, smiling and waving.  Bobby went over to meet them.
“Wow, Bobby!” squealed MĂ©lisande, “you’re so tanned!  You look like you’ve been in Italy or something!”
“Nah, Mellie – just Devon.  But it was sunny the whole time.”  He smiled.  It was quite nice to see her, in a funny sort of way.  Perhaps he’d had enough of male company for a while.  “How are you?”
Clarissa answered for her.  “Excited.  Less than three weeks to her birthday, isn’t it, Mellie?”
“Yes mummy!  I can’t wait.”  She looked anxious for a minute.  “You are coming to my party, aren’t you Bobby?”
“Yeah, I guess,” he sighed, with a wry smile.  “Can’t get out of it now, can I?”
“No, you can’t!  Yay!  It’s gonna be so fun!”
“Hi Clarissa.  How are you?”
“I’m very well, Nicole.  Yourself?”
“Fine.  Busy.  I’m just delivering the package” – she cast a glance at Bobby – “then I’ve got to get back.  Early appointment.  Ready to resume your, er, duties ?”
“Can’t wait to get my hands
”  She lowered her voice.  “I mean, get my hands dirty
”  She winked.
“Really, darling
  Anyway, I hope you don’t find your extra workload too taxing.”  She turned to Bobby.  “Well, darling, I’m off.”  She gave him a kiss on the cheek.  “Behave yourself..”
“I will, auntie.”
“Oh, and by the way, I’ve sent auntie Clarissa a couple of pictures of your outfit for Mellie’s party.  No
listen.  It’s one of these, or you’re Bobby the Boot Boy.  It’s up to you.  Just tell me whether you prefer pink or blue.  Okay?”
Bobby looked puzzled.  “What?”
MĂ©lisande frowned.  “No
  I’ve told all my friends he’s gonna be Bobby the Boot Boy
”
Clarissa turned to her.  “Just wait till you see what auntie Nicole has suggested, sweetie.  I’ll show you after breakfast.”  MĂ©lisande adopted her best sulking face.  “Please don’t put on that silly face!  Really!  Don’t you realise how embarrassing it would be for Bobby to appear in front of your friends in those skimpy little shorts?  Well?”
The sulky-face morphed into an evil grin.  “Yes, mummy
I do
”
Bobby was outraged.  “You!  I thought you were my friend!”  he rushed at her, and she fled screaming into the house, with Bobby in hot pursuit.  The women burst out laughing.
“What a little minx!” cried Clarissa.  “Poor Bobby!”
“Do you think he’ll like the alternative?”
“Like?  No.  Choose?  Yes.”
“Okay.  I must go.  Call me if there are any problems.”
“I will, Nicole
”

Chapter 159.

The stool was low, but quite small, so that Maria had to stand with her feet and legs pressed tightly together.  She really did look like a naughty child confessing her misdemeanours.
“Well, miss
see
it’s awful!  She’s got so much on me now, I’m so afraid to disobey her
I’m constantly trying to please her in any way I am.  Every now and then she hints how much she’d like to send stuff to my friends
  I think I’d die if they saw some of the videos
or even the pictures!”
She hesitated.
“Yes?  Go on.”
“You know
  I thought you were going to help me
  You said you were videoing her so that you could save me
”
“Did I?  Oh, maybe I did.  But Maria darling
  To be honest, I get such pleasure from watching those videos
  I know, I’m sorry
  But you have to admit, Paula’s got quite a fertile imagination.  I can’t wait to find out what she’ll do next
”
“But you promised, miss!”
“Now, now, Maria.  Please don’t adopt that tone with me!  Who do you think you are?”
She stood up and gave Maria a single stroke across her flank, making her jump and wobble on the stool.
“Sorry!  Sorry, miss!  I didn’t mean anything!”
Nicole sat down again.  “I hope not, sweetie.  Now tell me what you’ve been up to.  You mentioned a party
”
“Yes
last weekend
.”
“Tell me everything.  I should have installed cameras downstairs, shouldn’t I?”
“No need.  Her friend videoed the whole thing.  She sent it to me.”
Nicole sprang up.  “You have a copy?”
“Yeah.  On my phone.  It’s in my jeans’ pock
”
But Nicole was already on her way to the changing room.  She was back in a moment. 
“This one? Six stroke seven September?”
“That’s it.”
Nicole went to her dungeon desk and turned on her PC.  “I’m gonna download it so we can watch it on the big screen.”  She fiddled with a lead.  “Right
this one
  There we go.  Right.  So let’s see
  Play
”
She resumed her seat.  Maria craned round. 
“Oh, get down and bring the stood over.  Let’s watch it together.”
The video played.  An unfamiliar face – a young blonde woman – appeared on the screen.
“Hi everyone.  This is a video of Paula’s party, featuring Paula’s new puppy, Mitzi.  She’s adorable
but quite a handful
”
‘Mitzi’ was down on all fours in the middle of the room.  The guests sat or stood around, drinking and laughing.  Paula and Phillip were there, and nine or ten more.  ‘Mitzi’ was attired in her pink catsuit, her collar and leash, with a pair of doggy ears on a plastic Alice band and fake furry paws on her hands and feet secured and the wrists and ankles with pink straps.  A second female guest, a woman with black hair in a short bob wearing a little black dress, was kneeling beside her kneading her breasts enthusiastically, every now and then pinching the nipples, making her frown and whimper.  Then she picked up the leash and stood up, and began walking Mitzi around the room so all the guests in turn could say hello and pat her.
“Good Mitzi!”
“Does she bite?”
“I hope she’s not on heat!” said one woman.
“I hope she is!” said the man sitting next to her, with a leer.
“David!  Really.  There’s nothing you could do about it if she were!  She’s all nicely sealed in.”
“And I have to tell you that both the rear orifices are already occupied!” laughed Paula, eliciting delighted laughter from her guests.
“But the front one’s still available,” remarked the black dress, slyly.
A chorus of “ooh”s.
“Those breasts,” commented a middle-aged lady with a crooked smile, “those breasts are more suitable for a cow, don’t you think?  They look eminently
milkable.”
“Want to try, Denise?  Here, feel free.  Black dress dragged Mitzi over to the woman, who leant forward and weighed them in her hands, first one, then the other.  She grimaced, and raised an eyebrow.
“Mmm
impressive.  Large and firm.  Let me see what I can do.”
She slipped off the sofa and knelt beside Maria.  “This one first, I think,” she mused, wrapping her left hand around Maria’s waist and supporting her right breast in the other hand.  She stroked it gentle, tugging at the nipple and rolling it between her fingers, while the camera shifted round to Maria’s face for a better view.  Black dress shortened the lead, keeping her charge in place.  The woman worked steadily, peeping at Maria from time to time to see if her ministrations were having any effect, and grinned around her now attentive audience when after a few minutes Maria began to squirm and emit low moans.  A ripple of approval ran round the room, and there were cries of encouragement.
“Don’t stop Denise.  You’ve got her going now
”
“Play with the other one!”
“Ceri – give her a hand, why don’t you?”
And soon Ceri was kneeling the other side, and both Maria’s breasts were being squeezed and stroked, her nipples teased into stiffness.  She began to breath heavily, and groan with pleasure.  Then one of the men decided to get involved.  He was soon down on the floor stroking her bottom, and within a minute his fingers were between her legs, massaging her pussy.
“fuc-k!  I can feel the end of her dil-do.  When I push it
”
Maria let out a sob of ecstasy, and strained at her leash.  Paula took the leash from black dress, bent down and patted Maria’s cheek.
“Mitzi want walkies?  Yes, of course she does.”
The weather had been fine and dry.  The camera followed Mitzi and the guests into the garden, and while Paula walked her new puppy around the edges of the lawn, encouraging it to sniff at the flowers, the guests relaxed on the grass on in garden chairs.  David had a visible erection.  He was seated in a wicker armchair.  Paul led Mitzi over. 
“Look, Mitzi!  Your favourite uncle David!  Remember last time?  You like your uncle David, don’t you?  I think he’s got a little treat for you today, eh?  Go on, sweetie
good girl
find the treat.  That’s it
”
Obedient to her training, Mitzi began to nuzzle the bulge in David’s trousers, eventually taking the zip-pull in her teeth and inching it down, till his erection burst out, straight and quivering. 
“Well done!  David’s got a nice juicy bone for Mitzi.  Off you go, puppy!”
She began to lick eagerly up the length.  David’s head fell back and he gave a groan  of pleasure.  Several of the guests gathered round, filming with their phones.  Paula stood by, keeping her puppy on a tight leash.
Nicole stared.  “Maria!  You didn’t even hesitate!”
“It’s what I do, now.  Men and women.  At first I simply dared not refuse.  Then
I don’t know
”
“You started to enjoy it?  Is that it?  Tell me.  Knowing you, I wouldn’t be surprised.”
“Yes
  It’s true.  Just the feeling
being told what to do
knowing there’s no choice
being a little slut
all the attention...all those people, goggling and filming
it makes me so hot, I’ll just do anything now.  I can’t help myself.  Sometimes I want to escape.  But I know there’s no escape.  No choice.  And part of me needs it so badly
”
“What else does she make you do?”
“Everything and anything.  A couple of weeks ago she had five of the husbands or boyfriends around with their partners.  She’d dressed me up as a little schoolgirl – full uniform, white socks, tie, the lot!  She sat me on her lap.”
Nicole was keeping an eye on the video.  Now Maria was suc-kling happily on David’s erection, while he struggled not to c-um.
“They sat around talking about the things they could do.  All the while she had one hand up my skirt.  She'd put on latex gloves.  She had two fingers inside me, stirring me up like she was whipping cream or something.  I was gasping and squirming, the guests laughing at my predicament.  Then Phillip laid out a big latex sheet in the middle of the floor, and I was made to kneel on it and suc-k the men one after the other.  Paula’s trained me to swallow – “don’t you dare waste a drop!” she says.  But this day every one of them withdrew and came on me instead.  In my hair, on my face, on my uniform!  “Enjoy, Mitzi,” she said.  I’m Mitzi now, whether I’m her puppy or whether I’m just a person.  “And show it, too – come on, let’s see you masturbate.  I’m sure you must want to!”  One of the women filmed it all.  Yes, it’s on my phone.  Don’t watch it now.  It’s about two and a half hours.  I was totally frosted.”
Nicole listened open-mouthed.  Even she hadn’t expected anything quite like this.
“At the end they made me go down on all fours and lick the sheet clean.  And that woman said she knew a professional filmmaker, and they started making plans to produce some commercial films of me.  They were even thinking up titles – “Milky Mitzi”, “Mitzi Pulls It Off”, “c-um on, Mitzi!” – and so on.  Now that scares me.  Nicole – miss – I think I need some help.”
“Let me think about it, Maria.  First, I’ll just download those films, if you don’t mind.”

Nicole took Maria’s phone over to the PC and began downloading.  Yes, she’d think about it.  But first she wanted to see everything that Paula had been up to.  There were hours of video!  Super!  Tonight she could curl up with a nice bottle of white wine and see what had been going on.  Poor Maria!  But she was certainly getting what she wanted – and a bit more besides!  She'd think about it...  Yes.  But there was plenty of time...

Chapter 157.

Paula and Phillip didn’t waste any time.  Maria, Nicole and the girls were already watching them on the laptop.  Nicole had selected the minicam hidden in the elaborate cornice in the corner of the room nearest their bed.  They showered together and returned wrapped in towels.  Phillip climbed into bed naked, whilst Paula slipped into a figure-hugging black dress, to go with her almost black hair.  She was one of those women that can carry off simple clothes, and with the dress and her recently-acquired pixie hairstyle she was really rather attractive.  She sat on the bed fiddling with Maria’s and her own phone.  After a few minutes she placed both on the bedside cabinet.
“Done.  Right.  Let’s get her in.”  She raise her voice.  “Maria?  Maria – come on in, darling.”
Maria jumped as her name was called, even though she was expecting it, and hurried to the door without a word, not even stopping to thank Nicole for her “good luck”.  A moment later there was an apologetic knock at Paula’s door.
“Come in.  Close the door then.  Don’t look so terrified.”
“M-my phone
”
“Your phone?  Is that what you’re worried about?  Here it is.  You won’t be needing it for a few hours, unless you want to call a friend for advice!”  Another scream of laughter.  “I’ve done with it.  I’ve copied your entire list of contacts.  You realise what I’m saying.  If I want to – and fuc-k, darling, it’s a temptation, I can tell you – if I want to, a couple of clicks and they’ll all have your lovely little video!  Isn’t that fun?”
“Paula
  No!  Please.  I’ll do anything
”
“Oh, you will, darling, you will.  Anything and everything.  But behave yourself, do what you’re told when you’re told to do it, and there won’t be any problem, will there?  Oh, and remember it’s “madam” from now on – or “mistress”.”  She contemplated the trembling Maria for a few moments, then pointed to the floor.  “Come here.  Kneel.  Good girl.  Now let me explain the rules.”
“Yes, madam,” said Maria, dutifully dropping to her knees in front of her new mistress.  Paula leant forward slightly, and began to administer a series of gentle slaps to Maria’s cheeks, right, left, right, left.  Maria was startled, but knew better than to draw back.  They stung, despite her hood.
“So, Maria, from now on [slap] you’re going to be my [slap] little fuc-k-puppy, my [slap] obedient little fuc-k-puppy [slap] – for me to do [slap] just what I want to with [slap].”
Maria’s cheeks were burning hot by now, but the treatment continued.  “I’ve been thinking about it, [slap], thinking of a suitable [slap] little bitch-puppy name, [slap], and I’ve decided on [slap] Mitzi.  Do you like it? Well, do you?”
“Yes, madam.  Thank you.”
“I knew you would. [slap]  And I’ll get you a pretty collar, [slap], and a silver tag with your name on it, [slap], and my number in case you get lost, [slap].  And I’ll take you out for walkies, [slap], and but you a nice soft doggy bed [slap] so you can sleep near me at night [slap] in case I need some attention.”  She leant back.  “Your face is so red, Mitzi.  I guess you must be hot.  Let me give you something nice and wet to lick, puppy.  Here – off you go."
She slid forward a little on the bed, so that her skirt rode up.  Maria saw that she wasn’t wearing panties.  Also, that her pussy was pouting and glistening.  Paula gave a soft laugh.
“It’s your fault, Mitzi.  Slapping your face has got be all hot and bothered.  Now, you know what to do, and you’d better impress me or I shall have to get my whip out of the wardrobe.”
Maria, terrified by the thought Paula had the power to turn her life upside down and the touch of a button, set to work eagerly.  Paula sighed with pleasure and lay back, resting her head on Phillip’s chest.  For a while there was no sound but Maria’s regular lapping and slurping, and Paula’s quiet groans.  She opened her legs wider to provide easier access.
“God, Mitzi
  Where did you learn to eat pussy like this?  You really are a puppy, aren’t you.  Oh my god, I’ve hit the jackpot.  I can’t wait – oh, slow down a little, for fuc-k’s sake, or I’ll
  I can’t wait to introduce you to my friends.  My new little fuc-k-puppy on a lead.  You’re gonna make them so happy.  And if you’re as good with the men
  I’m sure you’re not averse to a nice bit of coc-k, are you?  No. I thought not.  Keep still, Phillip!  Wait your turn.”
Phillip did indeed get his turn, but a truncated one, since by that time the mistress of ceremonies was feeling in urgent need of his services.
“Mitzi?  You spent so many hours spying on us.  I bet all the time you were wishing you could get closer to the action.  Right?”
“Yes, madam.”  Maria had resolved always to answer yes to any question or assertion.
“Well, lucky puppy, now you’re gonna get even closer than you dreamt of.”  She unclipped the key from Maria’s collar, removed the padlock from her crotch zip, and slowly unzipped it.  For a moment Maria thought she was going to make Phillip enter her, but that wasn’t the plan.
“Get up on the bed, sweetie.  On your back.  A bit higher.  Good.  Now
”
She climbed up and straddled Maria’s face, facing her feet.  Her juices dripped stickily onto Maria’s face and trickled down her cheeks and the sides of her hood. 
“Phillip?”
Phillip slipped from under the covers and knelt behind her, his erect pen-is inches from her waiting pussy.  Paula subsided forward until her posterior was the highest part of her body, her breasts pressed against Maria’s waist, and slipped a finger into her new plaything, making her gasp.
“Ooh, nice and wet.  Good.”
She reached up under the pillow, and drew out a soft red ribbed dil-do, naturally shaped.  After exploring Maria’s upper thighs with the soft round head, she used two fingers to gently open her lips, and pressed it between them.  It slipped in easily, making Maria whimper with relief.  Paula pumped it in and out experimentally.  She could feel Maria’s warm body vibrating under hers as she did so.  She smiled.
“Phillip darling?  Slowly, please.  Mitzi, I hope you have a good view
  Ahh!  Yess
”
Phillip slid his whole length into her, in the manner she had prescribed.  Maria watched wide eyed as her pussy was stretched open, and a flow of juices was forced out, spattering her cheeks and lips.  In the next room the three watchers were riveted to the screen.  Barbara stiffened, and Kaiya squeezed her arm.  Even Nicole tensed.  In the space of a minute Phillip had quite lost control, however, and was pounding his partner oblivious to any restraint.  Paula, eyes closed tight in ecstasy, worked the dil-do back and forth.  Maria climaxed almost at once, her body shuddering against Paula’s, much to the satisfaction of that lady.  Soon the lovers’ combined juices, whipped into a cream by Phillip’s frenetic thrusting, were overflowing onto Maria’s face.  She opened her mouth and swallowed it greedily, then raised her head as far as she could to lick it off Paula’s pussy and clitoris.  It was Paula’s turn to be convulsed with orgasm.
“Phew
” whispered Nicole.  “She can’t complain she’s just an observer now.”
Paula’s orgasm triggered Phillip’s.  He cried out, gripping two handfuls of Paula’s flesh, threw his head back, and slammed his coc-k in as far as it would go.  Eventually he withdrew – and almost fell off the end of the bed.  A stream of c-um flowed from Paula’s pussy, deluging Maria’s latex-framed features.  Paula obligingly lowered herself onto Maria’s face, and rubbed her slimy pussy back and forth, in a definitive gesture of mistresshood.
“Enjoying your treat, Mitzi?  Good puppy!  Clean me up nicely, then I’ll let you do the same for Phillip.  Then we can decide what to do with you next.”
“Yes [slurp] madam!”
“Well, she really is such a good little bitch, don’t you think, darling?”
“She seems very obedient
and hardworking.  Maybe she can double up as our maid in between being a puppy-slut.”
“What a good idea!  Would you like that, Mitzi?”
“Yes please, miss
”
“I’m going to get you some nice outfits.  When I say “I”, you’re going to pay for them, of course.  Something nice I can introduce you to my friends in.  Oh, and you could lose a bit of weight,  Sign up at the gym over the road.  I’ll set you a target, and if you don’t meet it I’ll out you and find another puppy.  And we’ll need a garden kennel, for when you’re naughty.  And then there’s the toys and all the gear – plugs and gags and hoods
  Oh, Mitzi, there’s so many things to organise!  Isn’t it exciting?  The start of a new life for you.”
“Darling
?” began Phillip.
“Oh, yes dear, I’d forgotten.  Phillip would like his own little treat.  A nice, leisurely blow-job.  I’ll relax here and watch, if that’s okay.  Oh, and take a little video, of course.  You know I’m going to record all your adventures from now on.  I may end up making a feature film
”  She giggled callously.

“Time to go, I think,” whispered Nicole.  “We’ll get a full account later, and the cameras will capture everything, anyway.”
“Oh
” said Barbara, disappointed.
“So miss
  Are you going to use what we’ve got so far to foil Paula?”
“No, I don’t think so
”
“But you said
”
“I know.  But I think I’m going to throw her to the wolves.  It may be fun.”
“Miss!”
“I know, I’m awful, aren’t I?”
They crept out.  Phillip was getting quite noisy now, so there was no chance of them being heard.  They slipped out of the house and were soon in the car.
“Well I thought that was really cool,” said Barbara.  “It started me thinking about Chantal, and the things we can make her do
”

Chapter 155.

Nicole spent the morning giving the girls their first proper training session.  First, a talk about ethics – how everyone needed to agree on the content and intensity of a session in advance; when agreements could be varied; the occasional need, with certain types of people, to get the rules in writing; the need to be clear about the dominatrix’s own limits and restrictions; safe words and signs, the latter important when the subject had to be gagged; and so on.   After which they descended into the basement – Nicole didn’t like the term “dungeon”; imprisonment was only a minor aspect of her work.  Then a tour of the equipment – correct use, allowable variations and improvisations, dangers, safety measures.  She explained the proper use of floggers, whips and cane, the progression from the gentlest to the severest so that the subject should not be badly marked or injured, and how to test a subject’s tolerance.  Amongst other issues, she addressed the ethical question of filming.  She had had cameras installed in strategic positions, and would ask clients whether they wanted to be filmed.  A few did, but in such cases copies of the videos would be retained by both parties, but the mistress’s copy kept in encrypted form in a secure location and destroyed at the behest or demise of the client.  Zeta had assisted Nicole with sourcing the cameras, and it was three of the miniature type she had readied for the trip to Maria’s house.

It was three before they were ready to leave.  Nicole had prepared food-boxes for each of them with enough food and drink to last them through the night if necessary.  Maria’s room had its own bathroom, but they needed to be prepared in case it became too dangerous for the to leave whilst Phillip and Paula were still in the house; if they suspected they had been observed the secrecy of whole exercise would be compromised.
The girls were excited – it was as if they were being despatched on a secret and dangerous mission.
“The game’s afoot
” whispered Barbara, with a grin.
“Yes,” countered Kaiya.  “Better bring your revolver, Watson
”

Their impression was only reinforced when they arrived at Maria’s.  Nicole parked just along the street, and they walked to the house, which had a flight odf steps up to the front door.  They caught a glimpse of Maria peeping anxiously from behind the curtains of the front room, and when she answered the door she glanced nervously up and down the street to reassure herself her tenants were not nearby.
“Come in, come in
”
“Don’t worry, Maria,” said Nicole.  “Calm down.  Nice haircut.  Actually it suits you – makes you look slimmer.”
“Does it?”
“Don’t you think so?  Let’s see
  We should have, what
”  She checked her watch.  “
the best part of four hours?  Here, put this in the fridge,” she added, handing her a bottle of white wine.
“Thanks, Nicole.  Sorry, I’m in a bit of a tizz about the whole thing
”
“Of course.  But don’t worry about us being caught.  We won’t.  We’re quite cute when it comes to this sort of thing.  We even have a strategy in case we were discovered.  But we won’t be.  Now, why don’t you make us a cup of tea, then I’ll get the cameras installed – that won’t take a few minutes – then we can discuss how things are going to go down.”
