The next couple of years flew by for Casey and Amanda at University. The became great friendes and shared many fun times doing things together and experimenting with Casey's amazing growth powers.

Casey and Amanda both graduated and took a new step in there lives Casey became a model for many companies and many items becasue she could change her appearance and Amanda worked at a bank. They would definitely see each other a lot still because they lived in the same city.

Casey became the face of modelling more many companies and their items. She made a fourtune becasue of the multiple modelling contracts that she got. She was a model for playboy. There she was known as Sierra Erona a 6'4" godess with DDD sized tits a larger than average pussy and a big round ass with many curves along with it. Her second job was a bra model at Victoria's Secret. THere she was Sidney Russel, a 5'10" red hed with F sized tits that nearly explode every bra that she modeled. Her third job was a bikini model there she was Fiona Reid a 6' tall woman with EE sized tits cusrvy shape and very long, sexy and smooth legs that many people desired. She often posed revealing her superb cleavage that made many drool. Because of this some might be fooled into thinking that she was being advertised, not the bikini. Her fourth and final job was modelling for a dress company. She modeled their low cut dresses. Here she was Tracy Weston a 6'5" tall, black haired beauty. She had the biggest roundest ass of all the models and it showed in the dress the bottom was stretched to the near point of ripping, she had long legs and DD sized boobs which pushed the neck of the dress down to reveal amazing cleavage.

After a few years of Casey made a fourtune. She made millions to just show off her body in different outfits for different companies. She drove a nice car and had a mansion to live in. She had fun doing her job.

A couple of years passed and she met a man named Mark. He was handsome at 6'4" with large muscles and a bright smile. After many dates they both loved each other and became married. Casey knew that at some point she would need to tell Mark about her amazing power.

One day when Casey returned to the mansion after a day of work she called Amanda. Mark had left for a business trip and wouldn't return until very late that night. Casey told Amanda that she felt kind of lonely without Mark and needed some company. Amnada came over after her day of work was over. When she arrived they chatted laughed a bit and had a fun time then Amanda brought up the fun time they had at university and Amanda wanted to rekindle the magic. Casey eagerly agreed and they went to the bedroom. Amanda stripped down to her panties while Casey was in the bathroom. Afetr a long time Casey finally came out in her black bra and g-string. Amnada was already on the bed in her panties and Casey crawled on her. Casey made her boobs grow to F sized and Amanda watched as Casey's tits slowly spilled over her bra and tore it off.then Casey crawled over Amanda and Amanda paused looking puzzled.

"What do you have down there?", she said pointing to Casey's black g-string which seemed to have a small lump in it.

"Sit back and watch" said Casey.

They both kneeled at opposite ends of the bed and Amanda watched as a large penis was emerging from Casey's g-string. Casey was in the bathroom becasue she was giving herself a penis!

Casey still remained a woman except without the vagina. Casey grew her penis to a foot long. Amanda began to storke it and then put it in her mouth until Casey became hard. then Casey inserted it into Amanda and she pumped until her load came out. Amanda screamed in pleasure then pulled out.

"Bigger!" she yelled.

Casey lay flat on the bed as Amanda knelled to the side and watched Casey's penis grow, 2' then 3' eventually to 4 feet in length. Amanda stood straight up and examined the largest penis ever. She rubbed it and sucked it then she climbed a top it as it supported her in the air.

In all the excitement she manged to yell once more, "Bigger!"

Amanda could feel Casey's penis grow inside her and Amanda was being raised higher into ther air until her back touched the 9 foot tall ceiling. Casey lay flat on the bed at 6'2" with a fully erect 9ft penis reaching the ceiling supporting her freind. then Amanda watched as Casey grew under her. Casey's legs began to lengthen out then her boobs began to grow until they were beach ball sized. Her torso grew until she was 9ft tall. Casey was now laying on the floor across the bedroom to allow more space and she grew again this time strecthing out to 12ft. She could grow no more as she was double the height of Amanda with a penis three feet taller than Amanda. THey reached orgasms and Casey unloaded a huge amount of cum into Amanda and they yelled together in pleasure. And then the door opened...

Mark stood there in utter shock as he saw his wife laying across the floor of their bedroom at 12ft in length with a 9ft long penis and then noticed Amanda at the end of this giant penis naked.

Casey quickly shrunk down to normal size and turned her penis back to a vagina and found something to put on and Amanda grabbed some clothes and left the mansion.

After Amanda left Mark became furious at Casey. Casey managed to calm Mark down and eplained to him the story of her powers.

"So you can change into anything?" asked Mark.

"Yea, all or just part of me." Casey replied.

Mark wanted to test this out even though he got a short glimpse of it earlier and he asked if Casey was up for it. Casey was able to manipulate her insides to give her a increased stamina. Casey also explained to Mark that she was those 4 different models and that's how she had a high income. It all finally made sense to Mark now.

Mark lay on the bed ready to see what his wife would do.

"I'll let you make the first move honey," said Casey.

"Start with your boobs." said Mark.

Mark watched in awe as his wife's tits were growing from DD size to EEE. Here tits became round and were overflowing her cups. This caused so much stress on her bra until it popped loose. Casey was still leaning over Mark and he watched Casey's tits get freed form her bra then Casey nearly toppled on top of him because of the immense weight of her mammaries.

"Give me a moment." said Casey.

Casey now made her muscular structure bigger to support the weight. Mark watched Casey's muscles grow and bulge out to a normal man's size to support the masive weight of Casey's breasts. Casey made her biceps bigger until they bulged like footballs. She added muscle to her legs to make them more sexy and she gave herself a 6 pack. Mark was astonished at the transformation going on infront of him and he noticed that Casey's g-string was about to burst.

"I'll fix that."aid Mark, and he reached down to pull it off but just before he could Casey lengthend her body to 6'6" and the g-string burst. Casey kept growing until she hit 7 feet. She added more musleces to her frame. Her biceps exploded to the size of a male bodybuilder her back and pecs exploded with raw muscle as she was getting ready to exapand her breasts to match her huge stature. To complete the growth her breasts grew to two perfectly round beach ball sized breasts. Mark had his 7ft 250lb of all muscle wife literally suffocating him with all the pressure. Casey ripped Mark's pants off and grabbed his penis and put it in her soaked pussy. Her vagina muscles were crushing his penis with every pump. His screams couldn't be heard because his face was buried between two giant tits. When he unloaded into Casey she rolled off him and he gasped for air thankful that his wife got off him.

"I think that I like you before you could crush me," he said in between gasps of air.

Casey shrunk down to her normal 6'2" size but left her back muscles and pecs stronge to support the weight of her breasts which Mark insited she keep for a little while longer. Mark put his penis between Casey's mounds of flesh all the way into her mouth. Mark had a pretty big penis and he unloaded into Casey's mouth the last for the night and they both rolled over in ecstasy.

Mark knew this was the start of something great.
