Deep in an underground lab 28 year old Dr. Ryan Nevy was researching the effects of different chemicals on animals trying to make a new way to solve overpopulation by making humans more capable of surviving in different environments. So far his tests have been disappointing, having little results, until a small ant showed signs of increased durability and intelligence. Dr. Nevy studied the ant closely to see if he could use this to help humans. After a few months of watching it he noticed that the ant had started a colony and gave birth to thousands of other ants that seemed to have the same abilities, Ryan found this discovery fantastic since if it passed on genetically then humans would be able to pass it on as well.

After a year the colony had become massive and Ryan was focusing most of his time and resources in it. One ant, however, had managed to escape through a small creak and soon other ants followed. By the time Ryan discovered the creak it was too late, the ants had already escaped and many had gotten through the crevices of the lab and out into the world above. The ants spread out across the city rather quickly and made many colonies of genetically modified ants. Back at the lab Ryan was distraught at the loss of such valuable research subjects, but still had a small colony to study so wasn't too worried, after all they were just tough ants. Not all of the ants were gone, however, as one slowly crept towards the giant human and bit him on the ankle. Ryan looked down and saw the ant and went to grab it but suddenly felt dizzy as he passed out.

Ryan later woke up to find himself in a tunnel seemingly made of dirt. He looked around confused when an ant that was the same size as him walked into the tunnel and came up to him, he saw it's antenna twitching before another one came in and they seemed to talk to each other before moving as if to tell him to follow them. As they led him through the twisting tunnels and into a large space Ryan wasn't sure what to do or feel, it was almost too much for him. He then noticed a large ant which he surmised was the queen and the ants led him closer until he was a few feet away from her and she looked down at him with her large eyes. The queen seemed to say something to the two ants and they left the room, leaving Ryan alone with the queen.

Ryan wasn't sure what to do when the queen motioned to the sealed creak and seemed to demand he open it. Ryan looked at the seal and figured that if it got him out of this predicament he might as well and started chipping away at the small piece of glue he used. He was curious why the ants didn't do this themselves until he realized that the glue he used was probably poisonous to the ants. After a short while he managed to get the cheap glue out of the creak and the ants all poured out of the hole, knocking him out with them. Ryan landed on the ground and clenched his sides, the fall hurt like hell but he had managed to survive the fall with no serious injury from what he could tell. The ants had all but scattered and left him on his own on the tiled ground of his now gigantic lab. He tried to think of an escape plan but felt a soft rumbling after a short while, the sound kept getting louder and closer until the large door opened and Ryan saw the titanic form of his 25 year old assistant Claire standing in the doorway wearing a lab coat and her usual attire of jeans, blouse and flats. He started running to her for help when she looked down and seemed to notice him, only for him to hear her say something dreadful.

“Ew a bug escaped” Claire said before slamming her foot down on the miniscule Doctor and walking over to a table to look at some samples and notes. “I wonder where Ryan is, I was hoping to show off my new tattoo” she said as she rubbed a small butterfly tattoo above her left breast.

Above ground some ants had made it to a local playground and a child walked over and picked one up. He looked at the ant before it bit his hand and he put it down and left to go play on the swings.

Claire got home and kicked off her flats by the door, her day was the same as any other, look at notes left by Ryan and check the equipment and experiments to make sure everything was running smoothly. Only difference was that she hadn't seen Ryan at all today and was concerned since he was always there to make sure his tests were going the way he wanted, just in case she wasn't sure about something. She shrugged it off though since it's been a few years of her working with him so he probably trusted her on her own. She walked into her kitchen and started making herself dinner, humming as she did.

Ryan woke up and looked around, seeing a light blue wall in front of him he tried moving and found he was stuck to something. The memories of what happened suddenly flooded back to him, Claire had stomped on him but he hadn’t died like he expected, instead getting stuck in a small bit of gum residue stuck to the shoe, falling unconscious after a short while of Claire walking around. He struggled and after some effort managed to get free and as he walked around the shoe he guessed that he must have been in Claire's house as he heard someone in what must have been the kitchen and started heading towards them.

Claire finished making herself a sandwich and walked out into her living room and sat down on her couch and flicked on the tv to watch something for a bit before she got ready for bed. Ryan watched as his unaware assistant nearly stepped on him again as she walked past him to her couch and sat down, him continuing after her. As he reached her he saw she had one leg underneath her and the other was resting on the floor nearby so he walked over and grabbed onto her foot and started to climb up her, Claire not noticing the small man as she ate and watched the tv. Ryan got up to her knee when she finished her food and got up to put the plate away, Ryan barely managing to hold on as her leg moved at incredible speeds compared to his small body. Claire then headed up to her room and took off her jeans and gathered clothes for a relaxing bubble bath, Ryan falling to the floor along with the jeans and getting trapped in the material for a short while before managing to escape as Claire was leaving into the bathroom.

Living alone she didn't bother closing the door and turned on the water and started to fill the tub, putting in some soap and started taking off the rest of her clothes and taking them to her room to toss in her hamper while she let the tub fill. Ryan watched the naked form of his assistant walk past but also heard the water running and figured she must be setting up a bath or shower so she would be heading back and continued into the giantesses bathroom and looked for something he could climb to get some height so she could notice him easier. Looking around he spotted a small string dangling from something and started climbing up it. As he was climbing Claire walked back into the bathroom and turned off the water and got ready to get in, noticing one of her fallen out hairs on the counter she grabbed it and threw it away without a second thought as she climbed into the tub and lowered herself into the warm water.

    Ryan was climbing up the string when Claire looked at it and grabbed the top and carelessly threw it away, causing the small man to be swung around uncontrollably and let go of the hair and went flying through the air until he landing with an unnoticeable splash into the warm water of Claire's bath. He looked up and saw the giantess step in and lower herself directly on top of him, sending waves crashing everywhere and almost bringing the small man down with her butt as she got into place and the water calmed down. Ryan surfaced and saw he was right in front of her smooth stomach as the water calmly crashed into her and he started swimming to get closer before she moved again. As he reached her body he realized he couldn't see past her chest to her face and could see partially under the water at her legs when there wasn't a massive bubble island floating past. Ryan decided his best course of action would be to climb up to her face before anything happened that would possibly endanger his small frame and started to walk up her body.

    Claire meanwhile had no idea that anyone else was even in her house with her, especially not a small man in her bath trying to get her attention, she simply relaxed and let her stresses melt away with the grime on her body as she sat and soaked in the water with her eyes closed and clearing her head. She felt the small movements of the water on her torso and sunk lower into it, leaving only her breasts and head exposed.

    The world suddenly started shifting for Ryan as he was halfway up the giantesses body when the floor below him started sinking further into the warm ocean. He started running so he wouldn't get caught in the water and tossed around again but his small legs unfortunately we're not fast enough to reach high enough on Claires body and he was quickly left stranded in the water again. He saw Claire's body far below him (relatively) and knew he would have to hurry and get to her for help otherwise he could end up down the drain or worse. He kept a steady pace as to not exhaust himself too soon but still make decent progress with his diminished form and had reached Claire's floating cleavage, unfortunately not seeing any “land” and had to keep swimming further up. As he swam through however Claire began to move and the canal between her breasts started to close, with Ryan right between them.

    Claire started to think about Dr. Ryan and how she wanted to try and show off her tattoo to see what he thought and started to slink her hand lower into the water and start to rub herself slightly at the thought of the doctor. After a little bit she started to masterbate, grabbing one of her breasts and groping it while she pleasured herself with her other hand, completely unaware of the storm she was subjecting the very same object of her fantasies to.

    Ryan got squished between the mountains of fat and flesh and heard slight moans coming from the woman he was trying to get help from and blushed as he was pressed into her breast. Shortly he was pressed out from between the moving mountains via a combination of the water and soapy bubbles and tried to swim out of the way, quickly realizing that he was having no effect on his direction at all and turned to see himself heading straight for Claire's other half and began to swim faster, not wanting to get caught up in something that could potentially injure if not kill him. Sadly his efforts were in vain as the waves kept pulling him closer and closer to her until he was right at the base of her hand and was getting slammed into the moving limb as it suddenly came out of the water and reached over for something that Ryan couldn't see. With no time to escape Ryan watched as the hand returned with a dildo and brought it down into the water, dragging Ryan with it as it did.

    Claire pleasured herself and orgasmed into the tub before pulling the plug and getting out, grabbing her towel to dry off as she did. She walked over to her room and put her dildo into her drawer and walked back into the bathroom to finish drying off.

    Ryan was barely conscious but could tell that he was somewhere moist and warm before he passed out.
