I've enjoyed the TF community for a long time and I thought I would try and contribute back and give a shot at writing. I know this isn't necessarily furry but I am planning on moving on to furry. Let me know if you find any grammar or spelling mistakes and feel free to comment. I hope you enjoy it and hopefully I will have more furry transformations in the future.

***************************************************************************************************************

Stacy ran along the beach in her dark blue one piece suit. An athletic girl, she was often told she would be on the varsity team in basketball once she became a softmore at her high school. A strong toned body with short brown hair, clear blue eyes, and modest breasts, she took a turn into the waves and crashed hard into a rolling swell bringing her to a complete stop. Logan, her boyfriend running after her, dived beneath the large wave and appeared behind her grabbing her waist startling Stacy.

"You scared me!" shouted Stacy.

Logan rolled his eyes and stretched his body out as the freak wave had passed and the water had become calmer. Stacy took note of his quiet response and also began to relax into the water when she noticed a small coin farther out. Slowly moving out towards the coin, it became deep enough that she couldn't touch the sand and realized that the coin was probably too far and not worth the effort.

Moving back towards her well boyfriend Logan, she had to admire his awesome body, how he was built to swim and was still very buff and slender with his bright blonde hair, and clear green eyes. Looking him over quietly, she asked "Do you ever think about swimming out really far and exploring the sea like scuba divers?"

Logan sighed "Of course I do but you know that I can't dive too deeply into the water because of my ear problem."

"Well what if I told you I found some gear that might allow us to do that?" Stacy responded.

"I highly doubt!" laughed Logan.

Quietly Logan often dreamed about exploring into the clear waters. Despite being on the swim team, he was restricted from diving or swimming deeply as this would cause intense pain in his ears and if he went too deep, would cause irreversible ear damage.

Hearing the doubt and intrigue in his laughter, Stacy dragged him out of the water towards the rented beach house her parents had let her use while they were gone.

"Let's get cleaned up and I will show you the shop and the equipment and then let you decide" smiled Stacy.

Arriving in the small store, it looked like any downtown store in a reasonably populated city. It had all sorts of the normal items like coffee mugs, paintings, and little bags of candy. The unique thing about the store was the young girl tending to the register and the large array of costumes behind her.

Smiling at the customers, she stated "I've been waiting to hear back from you Stacy! Did you decide on what you wanted to do?"

Stacy looked up momentarily forgetting her previous encounter, quickly remembered saying "Yep! I want the green mermaid costume! I brought my boyfriend so he could pick up his as well!"

Logan stared around in disbelief. There was no scuba gear or any gear of any kind that could help him with the ear problem. Trying to pull Stacy back out of the store and mumbling an apology, the small girl stated "Logan, I've heard so much about your ear problem, I know just what would help you."

Caught off guard by this girl's knowledge of his problem and the confidence in her voice, he released Stacy and slowly walked to the counter with her.

The girl gave Stacy a package wrapped in brown paper and pulled out another brown package for Logan. "I think this will be exactly what you are looking for. Remember that the effect only lasts for 12 hours. If you put them back on again, it will become permanent!"

Before Logan could open the package up, Stacy pulled him out of the door and back to the beach house. When they got home, Logan attempted to peel back the wrapping before Stacy stopped him and told him to wait until tomorrow morning when it was better light. She then pulled him to bed for a little romp before falling asleep.

The next morning, Stacy warmly woke Logan up with a kiss and a hug. Logan immediately remembered the diving costumes adventure they were going to have today. Pulling himself up, he put on his beach shorts and followed Stacy towards the back yard. It was a strange walk as Stacy usually only wore one piece suits since she could be very shy but for today, wore a two piece black bikini. However it was true that it was still so early that the public wouldn't be on the beach to see her.

Sitting on a little hill of sand near the back of the beach, Stacy unwrapped her green mermaid costume. Looking at it, it could have been easily mistaken for a small shiny green dress with fish scales for texture that fell down past her feet. Logan thinking it was cute, unwrapped his package and to his dismay, realized it was a slightly larger red dress that was cut perfectly for it to fall down past his feet as well.

Stacy looking extremely elated, looked over at him and grinned hard before saying "For it to work, you have to apply some lotion to your body and legs and put the dress on naked."

Logan feeling a bit upset over this new fact, warmed up to it as Stacy pulled down her bottom and gave Logan some lotion to get her ready. Rubbing her body up and down and under the bikini with a few little pinches and squeezes, finished covering her body quickly.

Pulling his shorts down, Stacy gave him the same treatment with a few quick rubs and massages before he was covered in the clear goo. It didn't feel sticky but rather somewhat warm and the sand wasn't sticking to it at all either which was convenient for putting on the next parts.

Stacy put on the dress first, stepping into the fine material and pulling it up towards her waist. Laying down on the beach propped up by her elbows so she could better watch any changes that might happen, she was slightly shocked when she felt her legs slowly grow into the dress so that the dress was suddenly tight on her legs. Breathing slowly, she could feel her legs almost become like one large appendage with no feeling in right or left side but as one large tail. The empty section that was between her legs in the dress also fill out with the end of the dress wrapping around her feet giving her the appearance of a large snake. Moving her finger against the scales on the dress, she felt wonder as she could feel her hand brushing her fingers on the scales and the pain at pulling a scale the wrong way. Starting to freak out, she tried to see if she could pull off the dress at her waist when she realized that it had become merged to her skin and that small green scales were slowly starting to creep up towards her upper body but felt better when she realized that they stopped under her belly button. Suddenly without any preparation, her body felt a surge of pure pleasure as if every muscle in her body was stretching at once. Laying back, she began moving her tail around on the sand in the throes of pleasure in directions her knees shouldn't have let her go as the tail slowly increased in size from 4 feet to well past 7 feet long. As the stretching ebbed, she felt the end of her tail become slightly heated as suddenly a large webbed green fin slowly push out and grow to about 2 feet long and 3 feet wide. Feeling her upper body heat up and realizing that meant something was about to happen, she suddenly arched her back as a small fluke began to push out from her back that fell to the side allowing her to see it was also green and webbed like her tail. She felt a tightness around her chest as her bikini became strained as her small breasts suddenly pushed out making her feel better equipped. Her skin became more fair and her hands developed webbing between them. She could feel that she was much stronger now than ever before. Her breasts also became slightly covered in small green scales to help pull them down against her body. Finally, she suddenly felt a heat on her face and along her torso as hidden gills flexed themselves on both sides of her body finally allowing herself the ability to breath

Logan turned away from Stacy and stepped into his somewhat girly red dress and immediately began feeling the heating feeling similar to Stacy. Much quicker than Stacy however, he could feel his legs grow and fill out the dress and realized it had become one with his waist as small golden scales also crept along his body. Logan also was in mind numbing bliss as his tail expanded and watched in intrigue as his tail appeared. Feeling the pressure in his back, he arched his back out hard to feel the fluke slowly grow. He felt the heat along his sides, face, and ears. One notable difference from Stacy was that his body became harder and more chiseled. Without changing his form, he could feel his strength increase and knew he could defend Stacy if he needed to. Turning around and seeing his best friend and girlfriend changed into a lovely green mermaid, he feel into an instant and deep love for her.

Recognizing that they were both finished with their change, she grinned at him and asked "Do you want to test out some diving techniques?"

Smiling exuberantly, he responded with "After you, my lady."

Unfortunately they decided to do the change on an upper area of the beach and had to crawl towards the water with their significantly larger bodies. Strangely though, the scales seemed to ooze a clear fluid that allowed them to move along the sand at a decent rate allowing them to crash into the water. Inhaling sea water, they found it to be as easy as breathing air and their new tails allowed them the ability to move their lower bodies in any direction helping them swim in a quick and smooth motion. Swimming far from the shore and staying below the waves, they realized that the changes had allowed them the ability to see underwater and to resist the pressure of the water. Hugging each other's bodies in shock, they wrapped their tails into each other feeling the flukes, the gills, the smooth feeling of scales along their tails, the amazing flexibility of their fins and tails. Stacy also noticed their eyes had changed to a clear and hauntingly whitish blue pigment.

Deciding to move on, they began exploring the local sunken wrecks, moving through the windows and doors like large underwater snakes were more than either of them had hoped. In all the excitement and with their new forms, Logan began to realize Stacy was better equipped and so beautiful. She also kept rubbing her body all over her him squeezing her breasts and kissing him constantly. Feeling an erection coming, he realized he didn't know if he even had a penis anymore.

Halting in the water, Stacy swam back to him smiling with a knowing grin. "Honestly, I was wondering when this would happen!"

Reaching towards his waist where his penis had been, she gently pulled a small slit apart when suddenly his newly changed penis erupted from his body. Sporting a very long and large, milky colored penis made Logan smile hard at Stacy who was also grinning. Stacy immediately began to massage and kiss it so that it slowly became even stiffer. Tangling her body around his, she also pushed apart her lower section to reveal her beautiful sex which was responded by him pushing his dick into her has hard as he could. Stacy feeling somewhat shocked but fully aroused began sliding up and down his dick. It became apparent that she had changed too as she took the full mast into her body stopping every so often to kiss him and gaze into their new eyes. Pushing into her one last time, Logan released a huge amount of seed into her body with a little dribbling out and floating away from their love making while they lay their fully wrapped in each other's bodies.

They spent the next few hours testing their bodies in various ways before they both felt that the time was approaching that the costumes would end their magic. Swimming slowly back to shore, they lay their large bodies in the shallows playing with each other when they suddenly felt the changes receding. The tails became shorter, the gills disappeared into their bodies, the eyes faded back to their natural colors, and the fins and tails unceremoniously receded back to their original shapes before it was possible to take them off. Realizing they didn't have any clothes, Stacy held her small breasts and dress while Logan walked slowly in his red dress back to their house. Luckily it had been a full twelve hours, the beaches were already somewhat abandoned and they made it home with only a few strange looks.

Turning towards Stacy with a huge smile on his face, Logan asked "Do you want to do that again or see if we can get some different costumes?"
