Ashton patted his large ray gun. The measured just a little larger than the size of a small firearm, and it was tipped with a green circular bulb. It looks like something out of a science fiction novel, and it worked like one too. "I can't believe that worked!"

Clayton flexed his muscles. His once normal body now looked like a bodybuilder after Ashton used the ray gun on him. "You and me both. This is supposed to make you smarter as well, right? How does that even work?"

"Well, it doesn't make you know more, but it makes you remember more of things you forgot, and you'll be able to learn things much easier. Like, you can read a book and recall enough to put it to use." He turned to his albino rat in a cage. "I'm more curious if that intelligence boost did anything to Squeaker here."

The albino mouse, Squeaker, ran around in its cage. Like Clayton, she also had an increase in muscles. She looked like a very strong rat, but not so much that it was unrecognizable from its species.

Clayton picked up the cage curiously. "I don't think you'll be able to see any intelligence gain from it in that cage. What are you going to do with her? Are you going to read it some books or something?"

"Tomorrow I might try a few different things." Ashton smiled at the small mouse. "I don't want to put her through too much though. If I had to guess, her intelligence probably tripled if it grows like her body. Anyways, I'm going to go do some research. If you want to take pictures of yourself, you have to tell everyone about me."

Clayton nodded with a laugh. "You only spent 'how' many sleepless nights on this thing?"

"Well the first time I used it, Squeaker sounded like she was in pain so I had to stop and keep working on it until it was fixed. I mean, lab rats are expendable to most people, but they're living beings. I can't harm them."

Ashton patted Clayton's back. "I'm sure if she had the ability to thank you; she'd understand and thank you for being nice to her."

Once Ashton and Clayton left the basement, Squeaker raised her head up to the closed door, and then turned to the ray gun placed on the table. With her newfound strength, she pulled open the bars on her cage and crawled out. She looked at the ray gun on the other table. With her pink claws, she crawled down the table she was on, and then crawled up the new table. With her newfound strength, climbing and movement was very easy. She read the ray gun and noticed the lack of settings on it. She wrapped her long pink tail around the trigger and got to the front before she zapped herself with it again. She felt her muscles grow, and her intelligence multiply. She began to understand more and more about why humans did the things they were doing, and the lack of rights rats had, but how nice Ashton was to her despite how others treated lab rats.

Squeaker zapped herself again and grew rapidly. Once she grew to the size of a small toddler, she carried the gun with her outside of the basement.

In the house, Ashton waved goodbye to Clayton and walked up to his bedroom. He worked tirelessly and needed a sleep and a shower, but he was too tired to bother with the shower. Coming down from his high of creating a successful invention that made someone both stronger and smarter, Ashton went into his bedroom and fell onto the bed. "Now I just have to make them faster too." He said to himself. He pulled off his shoes and quickly fell asleep.

Squeaker waited until Ashton was asleep for certain, and then she brought the gun into his room. She zapped herself and made herself grow and grow rapidly. She continued to grow until she was seven feet tall, taller than Ashton was, and more muscular than any human could be. She took on human traits along with making herself grow, and it included showing off two large tits on her chest, but she didn't care. She then looked at the ray gun and realized there was one setting on it. With a grin, she changed the setting and zapped Ashton as he slept.

Ashton awoke a few hours later. He was in a horrible sleeping position to get eight hours of sleep. As he awoke, he felt much weaker than before. He looked at his arm and noticed it looked much smaller and weaker than before. He then looked at his torso and it was thinner and weaker as well. "What? What happened?" He then turned up, and his eyes widened.
There was a massive white furry rat anthro on top of Ashton. The anthro looked familiar, but she was also incredibly powerful. "S-Squeaker?"

Squeaker nodded. "Oh yes. I have an IQ well beyond that of an average human." She spoke in perfect English, though her voice was high pitched. "And the strength well beyond one too." She held up the gun as she pinned Ashton's body down to with her knees. "Now, I should return the favor with you being so nice to me, to be nice to you." She squeezed the gun and destroyed it with her bare hands. She held it just off the bed and let the broken parts drop to the ground.

Ashton's eyes widened. "H-hey! Destroying something that took weeks to make isn't something I'd call nice!" He struggled to pull himself free, but to no avail. Squeaker made him weak and puny with that gun. He was glad that his intelligence didn't drop too.

"You don't understand how pets work." Squeaker grinned. "See, you keep them in cages and you prevent them from harming themselves with dangerous tools such as those. I'm protecting you from yourself. We're going to redo your entire bedroom so you can't harm yourself. But first..." She leaned down. "You're going to teach me something that no human has ever taught me, and that is how to make love."

Ashton gulped audibly as he stared up at Squeaker. He had a very strong feeling that she was going to top, and he was not going to get out of this any time soon.
