Cuvo laid there on the cold metal slab, covered only by the white boxer briefs given to him by the lab. His eyes opened to see what looked like a giant death ray straight out of science fiction movie. The tip of the device was emanating smoke, having recently been fired. To his right, the doors opened with a slight hissing sound. In walked Nurse Meqi, the kind dragoness that walked him through the entire procedure beforehand. She began to undo the straps that were holding him down to the table.

“Everything seems to have gone well Cuvo. We just need to follow up on post-procedure protocols. It’ll only take a few minutes.”

Cuvo rubbed his wrists and ankles while Nurse Meqi grabbed a measuring tape, clipboard, and pen. He was sitting on the side of the table when she walked back. Cuvo was ready to finish up so he could get paid, go home, and have fun.

“Could you stand over in front of the mirror please?”

Cuvo walked over to the mirror. He still looked like the same six foot tall gray cat before he walked into the lab. He held onto his boxers, which were a bit loose from the procedure. Then Nurse Meqi stood behind him, giving him a reminder that he was not six feet tall anymore. He kept straight as she measured his height, as well as the length of other appendages. She scribbled down the information, then stood right behind him. Her six foot frame making him look even smaller than he already felt.

“As we discussed before, the procedure has permanently reduced your height to five feet tall. The rest of your body has scaled down to accurate proportions as well.”

“Well that’s good news. Anything else?”

“We need to weigh you to make sure your mass has scaled accurately. After that, we just have to test that the main focus of the procedure works, then you will be on your way.”

Cuvo walked over to the scale right next to the mirror. Nurse Meqi leaned over his shoulder to see his weight. Her brown hair brushed against the side of his head as she looked it over.

“Seems your weight scaled down more than it should’ve. Let’s give your muscles a check.”

Cuvo flexed the muscles in his arms and legs while the nurse measured them. She also gave them a light squeeze, which got a blush out of the cat. She wrote down more notes.

“Seems your muscle mass was reduced more than expected. We’ll have to adjust the settings of the device for the next subject. Don’t worry though, almost everything else seems to be in working order.”

“Almost everything?”

“Well, we have yet to see if the focus of the experiment works. Normally we would give the patient a porn magazine, but your contract does allow for a hands on test.”

Nurse Meqi slowly unbuttoned her shirt, exposing her brown-scaled torso and the fact that she was wearing nothing else. Her breasts weren’t as massive as some of the hypers Cuvo had seen walking inside, but they were still fairly large. She pressed his face into her breasts, leaving just enough of his head exposed to look up at her. As she moved her hands down Cuvo’s sides, his boxers fell right off.

His mind began to fill with thoughts of having sex with this dragoness right where they stood. He thought about the vixen he saw with tits big enough to make his whole body disappear. He thought about the macro wolf and his well sculpted muscles and all the body parts he would hump madly. His mind swirled with these thoughts. His erection felt like a steel bar rather than flesh. His crotch felt hot as fire, and his fingers felt ice cold. As he stared into the nurse’s eyes, she smiled.

He couldn’t hold it back anymore. He needed to release and he needed to do it now. While still stuck where he was, he began to hump her stomach. He didn’t care that he was shrinking. He didn’t think about what was going on. He just needed to release. As he humped like a madman, she simply held him and smiled. She walked over to a wall, and pinned him against it. His mind went from a thousand thoughts, to none as he ejaculated. His load dripped from the nurse’s lower torso.

Nurse Meqi let him go from her grip. Cuvo tried to stand on his extremely shaky legs, but they gave out and he sat on the floor. She gave a light chuckle, and wiped herself off with a  towel. She tossed the towel to the cat, who was still in a daze. He tried to wipe himself up as the dragoness put her shirt back on.

“Well, it seems the experiment was a complete success. During your little test, you managed to shrink down even more. If I had to guess, I would say three feet tall, give or take a few inches.”

Nurse Meqi reached into a cupboard and gave Cuvo a shirt. The shirt went all the way down past his knees, and hid most of his arms. He barely met her at her stomach at this point. He could barely see over the table she leaned against as she spoke.

“We here at SexSize Industries want to thank you again for participating in this experiment of our new artificial ERS Inducer. I’ll be right back with some water, as well as your payment.”

With that, the doors hissed open, and closed. The slightly shrunken cat sat on the cold floor in waiting. Cuvo knew Erectile Redusin Syndrome was a serious birth defect. His older cousin discovered he had it at eighteen, and never left his house since. Shrinking from sexual stimulation, then stuck at whatever size you sexually release at until someone can get you to a hospital to be regrown. While they invented medicine and medical procedures to help people with this issue, the sex industry was interested in the possible application of inducing ERS in people. Cuvo was told this giant device edited his DNA to give him an articial version of Erectile Redusin Syndrome. The money from this long term study would pay his apartment rent for the next two years, so he had no complaints. The doors hissed open, and the tall brown dragoness had returned with water and a paycheck.

“Here is your paycheck, as well as some water to speed up you regrowth. We added a small amount of protein powder, which is essential to the regrowth due to how ERS affect the proteins in your body. While anything with protein can be substituted for the powder, the powder does have the best results.”

Cuvo quickly drank the small glass of water. The cold water down his throat, sent an odd chill through his body. He felt like a balloon that was slowly inflated as he watched his arms and legs slide out from his previously massive shirt. Nurse Meqi chuckled, and handed him a pair of shorts. He slid them on, and tied them tight. She also handed him a garbage bag. He looked inside to see his old clothes, and tossed his paycheck inside.

“Now that you’re almost back to size, why don’t we get you outside? The caretaker you requested is ready to take you home.”

It was a short walk through a corridor before Cuvo was outside again. The sun was still shining, but was now an hour or two away from sunset. His view of the sun was cut off when a familiar blue pickup truck appeared in front of him. The entire truck leaned away from him as the driver got out. The driver walked up to the nurse.

“You must be Tuqa. I’m Nurse Meqi. We spoke over the phone.”

Tuqa was Cuvo’s apartment neighbor. The lion was a good twenty years older than the cat, and was admittedly the better looking of the two. They used to be the same height. Still rocking a full and luxurious mane in his mid-forties, as well as amazing muscles. He had his job as a construction worker to thank for his muscles. He didn’t have abs, but he did have a semi-prominent pot belly as hard as a rock.

Cuvo climbed into Tuqa’s truck while the two talked a bit more. She explained that Tuqa’s new job as Cuvo’s caretaker was as simple as checking in on him daily. She handed him a list of phone numbers to call in case they ran out of protein powder or had an emergency.

“If anything strange happens, just give us a ring. We’ll also have your paycheck sent to your apartment by the end of the day.”

“Thanks nurse! You have a good one now.”

“You’re welcome. Have a wonderful day.”

Tuqa walked to the driver side of the truck, and pulled himself into his seat. The truck shifted into drive, and sputtered off. Cuvo looked out the window, watching the buildings pass by. When they stopped at a red light, he turned back to the lion.

“Thanks again for picking me up Tuqa. Would’ve been awkward to go on the bus in a pair of cheap shirt and shorts.”

Tuqa smiled and tousled the gray cat’s short black hair. His hand was now large enough to cover his whole head. The twelve inch difference made Cuvo feel like a kid in comparison. As the cat saw he was eye level with the lion’s pecs that strained against the tank top, Cuvo knew his intentions were very adult.

“No problem Cuvo. In fact, I should thank you for this caretaker gig. Company lost a major contract and had to make cuts. I figured it was gonna be weird at first, but this will hold me over for as long as this experiment runs.”

“At least we both got bills squared away with this experiment. Though I’ll need to scrape some money together to get some new clothes. I don’t want to walk around in clothes that are too big.”

“Thrift shop down the block is having their dollar sale tomorrow. I need some new shirts too, so we could go together.”

Tuqa soon pulled into the parking lot of the apartment complex. It was only four stories tall, and had the ugliest brown brick for the outside. He shut off the truck and got out, soon followed by Cuvo. They walked up to their apartments on the second floor.

“How does ten sound Cuvo? We could get some clothes, and I could make lunch after.”

“Sounds great. See you tomorrow.”

They both unlocked their doors, and went inside their apartments. Tuqa went to reheat some leftover steak. Cuvo however, was aching to have a bit of fun with his artificial ERS. Nothing too crazy, but at least find out how fast it works. His apartment was essentially a studio apartment with a wet bathroom in a closet. Making himself smaller would make the place a little less cramped.

He walked over to his bed, which had a few shelves at the foot. He reached in the back, and wrapped his fingers around a massive hunk of rubber. He pulled out his dildo. It was called the Ballistic Missile. Eleven inches long, three and a half inches across, and nine inches around. He couldn’t even wrap his hand around it before he was shrunk. He couldn’t fit the head of the penis into his mouth, or his ass. It was big, and it could be so much bigger than him. Cuvo sat on his bed and ran his fingers across his crotch. The thought of being smaller than this already massive dildo was a very enticing thought.

He kept thinking of all the things he would do when he got small enough. As his clothes loosened, he thought of his shrunken body being pinned under the dildos massive weight. He thought of a massive hand pressing him into the dildo. He thought of Tuqa’s hand, his massive hand holding him in a tight grip.

Cuvo thought of crawling over Tuqa’s massive body for a few minutes. At this point, the cat had already shrank out of his shorts, and was almost small enough for his whole body to fit through the neck hole of his shirt. He had pulled the massive dildo inside the shirt, and he had sweat enough to run his whole body against the monolith of rubber with ease. He was roughly twice the size of the dildo, but dwindling fast as he fantasized about his older lion neighbor being massive.

As Cuvo saw that he was almost the same size as the dildo, he used as much strength as he could muster in the moment, and rolled it on top of him. He licked the tip of the dildo as he humped it like mad. In his mind, this was Tuqa’s dick, and he was purposely pinned by him. His thoughts were indiscernible as the dildo started to dwarf him in size. All Cuvo could think about was humping this massive dick, and getting smaller. Being smaller than the dildo, being smaller than that dilf Tuqa. Being smaller, so much smaller. His body was screaming to climax, but he wanted to be just a bit smaller.

His body couldn’t take any more wait. Cuvo felt the peak of his climax through his entire body as he came onto himself. The stream of semen covered his crotch, and pooled  around him. He shrank a little bit after releasing his load, which made the load look a bit larger than normal. As the cum soaked into his massive shirt and his fur, he wiggled out from under the dildo that was now the size of a large couch. He guessed he was roughly ten inches tall since the dildo was slightly bigger than him. He climbed over the dildo, and to what he believed to be a shirt sleeve. Crawling through the hole, Cuvo poked his head out to see his now much larger apartment. He saw his digital alarm clock down at the other end of the bed. He had been going for a half hour. 

“Ten inches tall from a half hour of beatin’ off. Amazing.”

As Cuvo reveled in the moment, he was harshly reminded that he didn’t have dinner. He walked out of his shirt to the side of his bed. He hopped off from the top of his short shelves to the floor. The shelf was as tall as he was, but stretched off like a long hallway. To one side, there was pretzels in a plastic bag, sealed by a large bag clip. Luckily, it was easy enough to push the clip enough to work the top of the bag open. He reached in for pretzels and pulled out three long pretzel sticks. If he was a few inches smaller, they would’ve made great walking sticks.

He ate the three pretzels with haste. He tried his best to re-seal the bag, and climbed back out to his floor. A bit of his fur was soaked in cum, he ten inches tall, and didn’t think about either thing when he hopped off his bed. He looked over to his pile of dirty laundry he was too lazy to put in a basket.

“Well, it’s better than the floor. I'll have to try and Tuqa's attention tomorrow.”
