Ok so it's take me a while but here's the last chapter if you havent read the first ones their here somewere and you need to read them first.

Sean went from a blissfully erotic half sleep to terror filled wide awake when Mandy screamed in her orgasmic release. He tried to yell for Sandy but no sound escaped his lips, and as his eyes made contact with the gorgeous amazon straddling him  his desire to do so also left him.
Sean knew deep inside himself that this growing muscle goddess was Mandy, Sandy's older sister and that he should be fighting to get her off, but his body was betraying him. Mandy's mouth curled into a devastating smile as she rode the waves of her orgasm and when she opened her eyes they seemed to bore right threw Sean. Leaning closer to him so her lips brushed his cheek Mandy cooed in an ultra sexy, deeply feminine voice.
" That's right Sean don't fight me, just relax and let me take you were you've never been before."
  As she spoke Mandy again started to ride Sean pressing him deeper and deeper inside her and with every thrust more and more power flowed into her, making her bigger, stronger and more intoxicatingly beautiful!
Sean couldn't help staring at Mandy as she drove herself onto him again and again and got bigger and bigger and sexier and sexier.
" Mandy!" he struggled to whisper as he forced his eyes to look away from the hypnotically attractive behemoth.
" You cant do this Mandy!" he blurted out trying to resist looking back at her.
" I love your sister and I can't betray her this way."
"Ah Sean " Mandy said as she turned Sean's head back to looking at her with her now huge gorgeous hand.
"I need you Sean! I need you to give me all the power I've stolen tonight. But there's no reason we can't both benefit from this. You see I took a bit more from some of the guys then I really want so I'm going to give some to you. I think it's only fair don't you!"
With that Sean felt a warmth flowing into him from Mandy and although he knew he shouldn't he looked down to were Mandy was rhythmically grinding herself on him. Every time she moved he saw his cock getting bigger and thicker, he had never been small but now he was growing to porn star size and more!
Just then Mandy pressed herself tightly against him almost crushing him with her new weight. She cupped his head in one hand and kissed him like he'd never had anyone kiss him before. She was in command , she was the dominant partner as she forced her tongue deeply into his mouth forcing him to kiss her back. Breaking the kiss off she pulled on his lower lip with her teeth as she withdrew and then nibbled on his ear and softly purred into it.
" Oh you like that don't you Sean." she said as she peppered him with soft little kisses each of which seemed to leave a tingling sensation.
" Oh yes you sure do and so do I. Take a look at how much I like it Sean, take a long hard look at me!"
As she said these last words Mandy cupped Sean's head in her now massive hand and tilted it up so he could watch her growing body!
Sean couldn't believe how big Mandy was getting, she was already as large as Sandy and swelling larger and larger. Her tits were the size of volleyballs and being pushed forward on massive slabs of pectoral muscles. Her stomach looked like a cobblestone road, the muscles were so large and pronounced. Mandy's lats were growing like wings opening on her back while her shoulders were wider then an axe handle and filled with cannon ball like muscles! All this Sean took in in only a heartbeat but his heart almost stopped as he gazed upon the angelic features of her face. Sean's vision blurred as he was almost mesmerised by her beauty.
It was at this moment when Sean had almost completely succumbed to Mandy's new and rapidly improving charms that he saw the powerful hand of Sandy close around a huge swath of Mandy's golden like locks!.
" Get the hell of my man you freakish BITCH!" Sandy said yelling the last as she ripped Mandy from Sean's lap and throwing her clear across the room and threw a partition wall!
Sandy knelt down beside Sean her hair still wet from the shower and gently rested her hand on Sean's chest.
" Are you OK baby!" she said in a soft gentle voice.
Sean stared up into her loving face and turned away in shame.
" I'm so sorry Sandy… I thought… I thought I was dreaming and that it was you but it wasn't and I couldn't help myself."
"It's OK Sean, I saw enough to understand you had no choice, but who is she and how did she get so big!" Before Sean could answer the loft was filled with the deep melodious voice of Mandy as she walked back threw the hole she'd just made in the wall.
" I think I should answer that question don't you Sean!
I'm your older, wiser and now oh so much better looking sister you silly little girl"
Mandy said as she brushed of pieces of plaster from her prodigious breasts.
"And as for how I got like this don't you recognise this pretty little bauble I purloined from you earlier!"
As Mandy said this she flexed her massive pectorals, lifting and separating her cavernous cleavage to expose the blue necklace to the two lovers.
"You thief!"
Sandy shouted at her sister.
"I let you stay here whenever you need to and you reward me by stealing my stuff!
" Not only your stuff tonight dear little sister" Mandy said as she flexed her massive muscles showing Sandy that she now was larger then her.
"I've been quite the thief tonight. I've stolen from so many people that I've lost count, and I've barely begun to fence my stolen property. So if you don't mind I need your little sex toy their to achieve the maximum return on my loot!"
With that Mandy walked towards the two with an erotically arrogant gait and brushed past Sandy reaching for Sean.
What happened then was so fast that Sean barely saw Sandy spin and grab her sisters forearms pulling and lifting her backwards. The two then began to grapple with each other spinning and twisting, both trying to gain an advantageous position. As the two Titans struggled with each other blue electrical sparks started arching between them. Sean couldn't believe what was happening as a halo of blue sparks encompassed the two combatants completely. He hesitated for only a second and then reaching under the bed he pulled out the baseball bat he always stashed their for emergencies. Stepping up to the two amazons Sean reared back and drilled Mandy across the back sending vibrations down the bat and along his arms so strong he almost dropped it. Mandy seemed to buckle a bit allowing Sandy to gain the upper hand pushing Mandy more and more off balance. Gritting his teeth Sean started to swing short chopping stroke at Mandy's thighs and hamstrings trying two break her legs but the bat just kept bouncing off her as though she was made of concrete!
Mandy on the other hand was getting quite a kick out of the little guy trying to protect her sister, in fact she was finding the slight stings of his bat quite stimulating.
Sandy realised she was in the fight of her life as she felt Mandy start pushing back trying to regain her balance!
She now knew that her sister was defiantly stronger then her! God how many had Mandy absorbed she thought as she strained to hold back the stronger woman with leverage moves she'd learnt in self defence.
Sandy realised her cause was lost as she heard Sean's bat slamming away at Mandy but instead of pain she heard an erotic moan escape her sisters lips. Before she could yell at Sean to stop she felt her sisters arms swelling in her grip and then watched in horror as Mandy's body started to grow larger and larger at every strike of the bat!
Sean's arms were tiring when the bat snapped in his hands, holding the now broken handle he stared up at the seemingly much larger Mandy!
For Mandy each slap of Sean's bat had sent small orgasms cascading threw her body and with each cascade she grew and she grew. Until just as Sean's bat splintered against her hard muscles she swept her sister effortlessly into the air and hurled her against the brick wall on the far side of the room. Mandy turned toward Sean effortlessly snatching him into the air and embracing him in a vicious kiss.
" I'd say your my little sex slave now, don't you think Sean."
Dropping him to the ground she walked over to were her unconscious sister lay sprawled against the wall and lifter her up into a bear hug. Blue sparks started to ark from Sandy encompassing Mandy in a Blue Cocoon of energy as Sandy's body shrank down to her former size losing not only her muscles but her breast size as well. When it was over Mandy turned to Sean in time for him to see her eyes radiate an intense cobalt blue energy the same colour as the now glowing necklace. The stone then began to dissipate, slowly sinking right into Mandy! In moments it was gone leaving only the chain around her neck and a hungry look on her face.   

Hours later a now 7'6" Mandy left the loft dressed in Sean's largest t-shirt and shorts which on her monstrous frame were stretched to their limits. Not that she cared, Mandy was now past caring what others thought of her. All she wanted was more of what she had. Back in the loft Mandy had checked the yellow pages and found two gyms just a few miles away and seeing as she couldn't fit into Sean's SUV she decided to hoof it and who knew how many people she may pass on the way!
As Mandy started her walk Sean was awakened buy Sandy's quiet urgings. They were both naked and tied back to back by their wrists on the bed.
" What have I done." Sean whispered. "
I've created a monster!" He said as he hung his head at the thought of how many people Mandy was going to destroy now that she and the gem were one.
" Don't do this Sean, don't blame yourself for something she's always been but we never wanted to see!. Sandy said to him in a commanding tone he'd never heard from her before as she started to twist in their restraints.
" We need to escape before she gets back and we need to get up to the cottage before she feels it to!" Sandy's movements were becoming more frantic and she began shifting her whole body to change the position they were held-in.
The gravity of the whole situation was weighing heavily on Sean and so he was only absorbing some of what Sandy was saying as she did some freaky yoga move that ended with his head between her thighs?
" Cottage!" Sean said.
"Yes the cottage my love, because when my sister stole my size she didn't exactly get all the gems power from me, and in fact she heightened how attuned I am to it so although she absorbed that gem she allowed me to feel the presence of a much larger one near the impact sight."
" Ah Cottage!" Sean said in a more enlightened tone.
"But how are we getting out of these ropes dearest." Sean said.
" Oh I think you know baby now it's time for you to put that tongue to work and make me a big girl again!
As the two drove at a more frantic pace back to the cottage Sean's amazonian fiance explained that Mandy had taken  her size but didn't finish the job,
allowing her to keep the link she shared with the waitress and the cop! Now all that they had to do was get to the cottage before Mandy explored her powers further and sensed the other gem.
Meanwhile back at the loft an 8' tall Mandy was furious at the escape of Sean!
She had the power of a Hundred people flowing in her just needing him to release it and the son of a bitch had taken the SUV and ran!
" WHERE THE HELL ARE YOU!" she screamed so loudly it blew out a few of the lofts windows.
Were could you have gone she thought, trying to control herself, were oh were… And then she knew or more she could feel Sean's body, her catalyst in her mind. Oh this is even better the GPS she thought as she lept threw one of the shattered windows and plunged three stories to the road landing lightly as a cat and sprinting of in the direction Sean had gone. It didn't register at all to Mandy as she hit 70 mph running speed that the last of her clothes tore away, all she thought about was Sean and how very shortly he was going to make her a god.

An hour later Mandy reached the cottage and found Sean loading up the SUV with what appeared to be camping supplies. He didn't even have the time to yell to Sandy before she had him stripped his cock hard and inside her standing up!
She engulfed him in her massive arms pumping him into her and taking him in a passionate kiss that overwhelmed him to the point that he almost swooned. However Mandy controlled even that as she fed him strength and stamina . Then her orgasms hit and they hit like a hammer on an anvil over and over again. As she pulled back her head from the kiss Sean could see the glory that was her and he knew he was witnessing and even more disturbing enabling the birth of a goddess!
Mandy smiled down at him as she grew and the smile almost overwhelmed him. She grew to at least 9" tall and still the orgasms hammered away as her body swelled with stolen power, her muscles getting larger and denser with each hammer strike, her breasts expanding like the prow of a mighty ocean liner.
Her nipples grew and hardened and Sean felt compelled to suckle on them as Mandy screamed in an orgasmic maelstrom! Time for Sean stood still as he worshipped at the alter of Mandy's Ascension.

She lowered him down to the ground gently for he was her catalyst and although she was now a god she wanted more, and with him she could have as much as she wanted, whenever she wanted.
Sean stared transfixed by her omnipotence and she spoke to him of her plans for the future just her and him forever, but her lips didn't move it was like she was speaking directly to his mind.
Mandy was enjoying reading Sean's mind, seeing her body in all it's glory threw his eyes when she heard her sister call to her.
" Are you finished Mandy." came her sisters voice from behind her. As she turned she was going to say something to the effect of I've only just begun, but the sight of Sandy standing their engulfed in a corona of blue flames stole the words from her lips!
"Yes I think you are."Sandy said matter of factly then she snapped her fingers and Mandy's and Sean's worlds went black.
  Sean woke two days later in his Bed in the loft. The smell of bacon was in the air and when as he opened his eyes Sandy was their with a soft touch of her silken hand to his cheek and a tender loving kiss.
"Welcome back my love your just in time for breakfast." With that she stood up walked to the kitchen and as Sean's eyes followed her he saw a 6' tall strikingly voluptuous Mandy setting the table!
"Hey sexy." she purred at him as their eyes met. Startled he shot a look back to Sandy and she gave him her chagrined little smile. " She is my sister."
She whispered and then she winked at him and her eyes were the deepest blue cobalt.
