The rest of the day was spent working on adapting the GF unit for the new demands and Nikki made swift progress. Grant left her in the lab working late into the evening whilst he decided to have a shower. As he walked into the large bathroom upstairs he startled Katrina who had left the door open and was hardly dressed with nothing but a towel around her. She was dripping wet and he could see her hair laying flat against her back and shoulders with the weight of the water upon it and her long wet eyelashes standing out predominantly highlighting her big blue eyes.
“Oh sorry I didn’t realize you were in here”
Katrina smiled
“Grant if you want to sneak up on me you should do it when I’m in the shower and maybe you’d get a better look”
She winked and purposely adjusted the knot that held her towel just exposing half her impressive cleavage forcing Grant to glance down before he instantly looked away and she wiggled past him and down the hall.
Later that evening the three of them had eaten and they all sat drinking on the balcony when the subject of the next experiment came up.
“So Grants going to be a little shorter tomorrow Katrina”
“Really?”
Katrina smiled in a way that Grant didn’t particularly like as if to say she very much liked this idea.
“What an interesting start to my working with you both. How much shorter will you be Grant?”
He felt a little uncomfortable with the discussion and added
“I think if we selected the year I was 15 years old for the height parameter. That’s 1990 I was then perhaps 6ft, that would certainly prove the concept to shave four inches off”
Nikki gave a disappointed look
“But honey you would still be very tall at that size and I was looking forward to not having to look up to you so much for a little while”
Grant didn’t respond he felt a little insecure about falling into the 5ft realms with Katrina being quite a tall girl herself.
“yeh , how about it Grant that would be a real exciting test if you were a lot shorter, imagine the difference”
Katrina gave a wide grin and Grant stood up wanting to shrug the conversation.
“we’ll see ladies. I’m off for a work out if no one minds”
He left them alone whilst he began to pump some iron in the gym and he tried to filter out images of Katrina that kept creeping into his mind , he imagined her working out on the machine opposite pulling her arms back and forth and expanding her chest in the lycra outfit he had witnessed the day before. As this wonderful image entered his imagination he tried to block it out and wondered why he was beginning to fantasize about Katrina and her body, was it because Nikki had lost her curves and her daughter was so well formed? Whatever it was he tried to shrug it off.

In the morning Grant woke early and showered in the main bathroom. As he left the shower with his towel around his waist he was greeted by Katrina who was also wearing a towel which just barely covered from her breasts to her rear exposing some cleavage and a lot of leg just like yesterday. He wondered if she had timed her arrival to the bathroom in order to see him or was he being paranoid?
“Morning Grant, you’re looking very buff today”
She grinned and her eyes fell onto his muscular chest.
“You wouldn’t want to wash my back would you handsome?”
Grant smirked
“I don’t think that would be appropriate do you Katrina”
He tried to sound like he wasn’t tempted
“Shame, but if you ever need a helping hand Grant I do have a gentle touch”
She smiled and her finger nails dragged softly across his bare chest
“You know it’s going to be an interesting day today I’m going to look forward to seeing you taken down in size, maybe you won’t be my stallion man anymore”
Grant held her hand gently and removed it from his chest to her side and looked down at this blonde temptress
“I will still be taller than you Katrina and you are going to have to stop flirting with me before your mother catches you one of these days”
“I’m getting to you aren’t I Grant ?, but I cant help myself when your such a fox and I think you enjoy it the way you look at me sometimes….come and join me in the shower if you want”
She walked around him and Grant found himself compelled to look back as she did so and he knew he shouldn’t have. Katrina saw this and winked as she disappeared into the bathroom knowing his eyes were following her every move she hitched up the corner of her towel revealing a single smooth firm cheek of her pert bottom in a teasing display. Grant shook his head and went into the bedroom to dry himself completely off he was cursing himself for suckering into giving her a double take. He slipped on his black toweling dressing gown and went down for breakfast trying not to think of Katrina. Nikki was cooking and in a good mood , he saw she was dressed in a long black skirt with her black boots on and a tight blue sweater. She looked great with her long blonde hair tied up showing off her new younger looks. What he also noted a touch disappointingly was the lack of shape beneath that tight top. Katrina came down whilst he ate and she was dressed in short red summer skirt with a pair of high heeled sandals and a tight white crop top that showed off her firm stomach but simply advertised her busty frame by making her breasts seem larger than they were or was she wearing a padded bra today? He couldn’t possibly stare but compared to her mother her breasts jiggled and bounced as she moved around. Her hair was up in a pony tail and she looked a million dollars and stood by Nikki she also looked tall but he assumed it was those heels she was wearing. Grant took more notice of her height today considering the experiment and wondered if she wore those heels on purpose just to challenge him. She had to be 5 ft 11 inches tall he guessed now and if he became 6ft as he planned that would leave little between them. After the morning pleasantries and discussions about the breakfast news and events they all went down to the lab. Grant was a little nervous but knew that what he would do now would impress the funders with the results.
“Ok Nikki I’m ready we’ll use the GF on me today and set a short transformation say a few hours to take full effect and reverse it all tomorrow after a few hours of settling to ensure its stable ok?”
“sure”
Nikki smiled and Grant walked towards the GF about to take off his robe when he was aware of Katrina’s presence who was smiling sat next to her mother flashing plenty of bare leg as she was chewing the end of a biro with anticipation.
“erm Kat I guess you should look away now”
He instructed as he dropped his robe. Pretending she was looking away Katrina sneaked a peek at Grant disappointed that he was covering his manhood as best he could entering the device.
The door locked and Katrina looked across to her mother.
“What next?”
“Oh now we set the date. Grant honey what year again do we need?”
She called out and Grant shouted
“1990 any month!”
“ok”
Nikki walked over to the main pc to input the date when Katrina joined
her.
“mum can I activate the machine please will you show me how to do it”
“Sure, I guess if your gonna help you can start by learning the set up”
Nikki explained how to isolate just the height value of the subject and where to input the date.
“All set Katrina?”
“No problem mum”
She smiled and Nikki allowed her to use the system whilst she walked over to see Grant in the GF and watch the gas begin and in seconds it was all over. He slipped on his gown and Nikki shouted across to Katrina
“Kat what’s the absorption percentage rate showing?”
“Um “
She paused as she found the read out statistic displayed
“99%”
“magnificent”
Grant smiled and they all left the lab mission completed for now. Grant went upstairs to get dressed leaving the two women chatting in the living room. It was hot so he decided to wear some shorts and a t-shirt but strangely enough he noticed they felt a touch loose and baggier. Loosing 4 inches over a few hours he assumed would be pretty slow but it must have been kicking in already he decided. As he came downstairs his wife was watching some Australian soap opera with Katrina and he decided to give it a miss and went out into the sunshine on the balcony and lay back in a sun lounger for a few hours. It was gone midday when someone interrupted the light. It was the impressive silhouette of Katrina stood next to his lounger
“Hey handsome mums made some sandwiches care for a bite?”
She smiled and he followed her into the kitchen. He noticed as he did so that his shorts seemed very loose and he used the draw strings on them to fix them, as for his t-shirt it was baggier so he tucked the excess into his shorts and thought no more of it as they all sat down around the rustic kitchen table to eat.
“feel any different babe its been 4 hours nearly”
“yeh a little my clothes seem a touch looser “
He explained and saw Katrina nearly choke on her food. Nikki patted her back and her daughter excused herself
“Sorry that must have gone down the wrong way”
Having finished her meal Katrina left the table and made for the wine rack bristling with lots of very expensive rare wines displayed in an elaborate manor from floor to ceiling almost.
“mum , Grant, fancy a drink this evening?”
“Sure honey”
Nikki smiled and suggested a bottle of the finest red French wine which was nestled at the top of the display rack. Leaving her mother to get the wine bottle Katrina returned to her seat with 3 glasses prepared in hand and Nikki added.
“Well it cant hurt we haven’t really celebrated the GF yet”
She looked at Grant for his agreement to drink what was several hundred pounds worth of wine. “Why not”
He smiled and watched Nikki stretch for the bottle on her tip toes unsuccessfully.
“You can guess who put this one up there”
She grinned flashing a smile at Grant in defeat as her fingers didn’t come close.
“trying to make sure I don’t accidentally drink it one night eh babe?”
He grinned back at her and stood up from the table to help her out. As he did so he noticed his shorts almost slip off his hips but he managed to save them and drew the adjustable cords in as tight as they would go before the two women noticed. Grant walked over to the wine rack thinking for a moment that Nikki from behind seemed a lot taller than before, as she stepped aside he reached for the bottle and also didn’t manage to reach it.
“boy a few inches sure makes a difference”
He muttered and realized that perhaps it was also because he was in bare foot. He’d never had an issue with the top of the wine rack before? He reached up on tip toes but his fingers just failed to grasp the bottle properly and Nikki warned
“Careful you might smash it that’s expensive stuff”
“let me help”
Katrina piped up and walked from behind them both. Grant smirked and stepped aside as he watched Katrina reach up just raising a little on her 3 inch heels with her short skirt pulling on her firm rear and edging up with her actions to reveal more bare thigh. Her chest also caught Grants eye briefly as it was pushing out under her little top. If he couldn’t reach it she wouldn’t have a chance even with advantage of her heels he sniggered internally. But amazingly to Grant she pulled the wine bottle neck and lifted it down with relative ease. Smiling she handed the bottle to Grant and as she stood there before him he could instantly see that in those heels she was taller than him now!
Grant felt a sudden shock of realization surge through his body he was short and hadn’t seen a woman taller than him for a long time perhaps since his child hood yet standing before him was Katrina almost two inches higher perhaps even three for all he could tell. How had he become her height? Or was he in fact shorter than her? His mind raced with these questions and he stood there with his mouth gaping open for several seconds along with his wife who was equally surprised to see her daughter standing several inches taller than her previously very tall husband.
“What the?”
He began and Katrina stifled a grin by placing her fingers over her mouth.
“Grant, Kat is taller than you?”
“I am aren’t I, wow this is something”
Kat drew closer to Grant and squared up to him and he saw instantly that his eyes were lower than hers as he stared her in the nose.
“But, this can’t be right?”
Grant turned to his partner who having overcome her initial surprise concluded the same thought.
“Kat how tall are you honey?”
“You know mum I’m five nine and a bit”
“I guess she is wearing some high heels”
Grant logically decided the heel accounted for her height advantage.
“What these? They are low heels only two and three quarter inches not like my regular pairs”
“Kat will you remove your heels I’d like to see you measured up against Grant for a second”
Nikki suggested but Grant was reluctant to be compared to Katrina of all people yet a certain curiosity was stirring inside him. For now he let this pass and tried to refuse.
“Lets just measure me the old fashioned way don’t we have a tape measure handy?”
“Darling just stand still a minute, Kat can you back up to him”
Nikki ended up guiding the two together back to back and Grant could already tell his shoulder line was just below that of Katrina’s smooth tanned shoulders. He waited uncomfortably for the announcement as his wife judged their respective sizes.
“Well if you are five foot nine Kat then Grant here is at least an inch shorter than you?”
Grant turned to see Katrina smiling at him her eyes just lowering enough to make him feel that very inch as he double checked that her footwear was removed.
“She looks like she is six five to me”
“I do?”
Katrina couldn’t help but smile more broadly at his comment.
“Well she would darling because your brain is used to everything being calculated from your old perspective”
“What happened a miscalculation? I’m sure that I was six foot dead at the age of fifteen”
“Obviously not honey because my daughter is taller than you there is no denying that fact”
“Sure isn’t, shorty”
Katrina piped up and Grant frowned at her use of the word shorty.
“Kat go and check the GF input log and verify the date you set please?”
“Of course mum”
Katrina put her shoes back on and once more rose further above Grant who uncomfortable with this walked back to his wife as Katrina left the room.
“Wow there isn’t all that much between us either honey”
Nikki stated seeing her husband was barely taller than her stood in her heels. Nikki helped secure Grants very loose waist band and smiled up at him. Seeing his once diminutive wife almost at eye level was unsettling and made him appreciate her in a totally different light.
“Nikki your tall”
His description was obvious and a little lame but this was all he could think of saying as his mind tried to come to terms with his current lack of inches.
“Well actually I’m only five foot eight in these boots and I never felt tall in them around you before but now…”
She laughed in a cute fashion openly expressing that she liked this situation.
“..now I do feel tall and its kind of nice”
Nikki walked around Grant as if checking he was her husband.
“You like seeing me this way?”
Grant was curious expecting his wife to prefer his former dominant statistics.
“Yes I do”
She blushed a little and then unexpectedly kissed him on the lips full and hard which he soon returned.
“what was that for?”
He asked
“Because I wanted to and because I needed to feel what it was like without me raising up on tip toes and without you hunching over to meet my lips. Do you realize even when I used to wear my largest heels I had to raise up to kiss you but not now”
Grant realized she was right and it made him instantly feel his new height.
“Your right I was just stood here and you kissed me”
He was a little dumfounded by this occurrence normally with the eleven inches between them he usually instigated every kiss if they were standing and this was a nice unexpected benefit.
“You see there are advantages when your wife is more equal to you I wouldn’t mind exploring other advantages”
Nikki began in a soft seductive manor but was interrupted by her daughter who walked back in the room.
“exploring what advantages you two?”
She smiled and strutted across to them making her presence felt by moving close to them both as if
she wanted to continue drawing her comparisons with Grant.
“Oh we were just talking darling so what did you find?”
“The um machine is fine no miscalculations but…”
Katrina forced a look of guilt
