Desc: Erotica Sex Story: A lonely university scientist accidentally discovers that his experimental device to spur plant growth has an unexpected effect on his beautiful female lab assistant.

Chapter 1

Charles held the device in his hands. It vaguely reminded the 40-year old man of a ray gun and probably would more so if he didn't already know what it was. The light ray device was heavier than he expected. Above his test plants in the lab currently hung a light panel that emitted a wide range beam. The device in his hands compressed that range into a narrow, concentrated beam. It took him forever to get the device built. There were a ton of paperwork and stages of approval. He never actually expected to ever see the device, but apparently the wide beam had produced sufficient results to get the narrow beam device built.

Charles was a plant biologist at the university. Don't call him a botanist. He hated the term. He wanted to be known as a plant biologist.

He placed the device carefully on the table and walked over to his nine by nine foot square garden. The latest plants were already spreading out. The wide beam light panel above the garden had accelerated the plant growth by fifteen percent. Hopefully he now had that same light panel in a handheld device.

"Good morning, Dr. Kemp. What are you doing?"

He turned around to look upon Kim, his pretty 20-year old research assistant. He could have chosen a more talented college student to be his lab helper, but he always preferred an attractive girl.

"Waiting for you." He pointed at the table.

"You got the plant growth device!" she squealed and went over to the cylindrical object.

He admired her backside. Kim was only five foot tall, but she had some very nice curves. He often imagined what it would be like to view her excellent ass while his cock was in her pussy. He also frequently imagined Kim on her knees sucking his cock. He'd love to do all kinds of wonderful things with her.

It was fifteen years since Charles went out on a date. All he did year after year was imagine what it was like to fuck his current research assistant. They were always female. The rest of his sexual fantasies were about other lovely students in his classes or about other beauties around the campus. He jacked off nightly with the thought of some college girl in his head. Most often, it was Kim.

"Are you going to try it today?" Kim said excitedly.

"Of course! We've waited forever to get it. You get to choose the plant."

"I do?"

Charles nodded.

Kim stepped over to the garden and tried to decide.

"This one," she said, pointing. "The pink roses."

"Do you want to do it?"


"I am."

"Wow! You are so cool! Everyone thinks you are so stuffy, but you are not. They don't know you like I know you."

He wrinkled his nose at the "stuffy" remark, but his mind quickly drifted to fantasizing about Kim.

Kim picked up the device then almost it dropped it to the floor. It was heavy!

"Careful!" Charles warned.

She hefted it up and walked to the garden. She aimed at the roses but the weight of the device caused her aim to constantly drift.

"I'll help steady it," he said.

He went behind her and reached around. He grabbed the cylinder barrel with his left hand and with his right hand grabbed toward the back of the device.

"Doctor," Kim said.


"Never mind," she said. The professor apparently didn't realize he was cupping her right breast instead of the device. She didn't want to embarrass him.

Kim took aim at the plant and fired. The device emitted a hum for twenty seconds and shut off. There was no visible light on the plant. The device used light that was invisible to the unaided eye.

"Great!" he said.

He let go her tit. He was right. When she came in, he thought she wasn't wearing a bra. Her tit was so firm. The last time he experienced a tit so firm was when he was sixteen. It was with the fourteen year old neighbor girl, Kerri. She was also his first sexual experience.

"So now what?" she asked.

"We measure the plant tomorrow. You might as well go."

As much as he wanted Kim to hang around, there wasn't much for her to do today.

"You sure?"

"Go!" he said, waving her out.

"Thanks, Doctor." Kim was glad. This would give her more time with her boyfriend. She hated when all they had time for was a quickie.

"Charles," he corrected. He reminded her most days. He wanted to be known as Charles to her.

He watched Kim place her lab coat on the hook and leave.

He sighed. Kim would still be with him tonight. He would masturbate with the thought of the feel of Kim's boob in his mind. He flexed the hand that briefly held her tit.

Charles was surprised to see Kim standing outside the lab the next morning. Her normal arrival schedule was later in the morning after attending his class.

"You're early," he commented.

"I couldn't wait to find out how much the roses grew!" she said enthusiastically. She still could make it on time to her first class.

"You know it might not have worked," he said, trying to ease any possible disappointment. Thousands of dollars were spent on failed experiments with the hope that something would eventually succeed.

"You have to believe!"

He unlocked the lab. He opened the door and motioned for her to go in first. She raced to the garden.

Kim screamed. The scream was so loud that Charles hurried to the garden. It sounded like she was hurt.

"Look!" she shouted.

Kim was okay, but he didn't notice her. He stared at the pink roses. They had doubled in size overnight. The device worked! The device had produced incredible results.

"You did it, Doctor!" Kim praised.

It worked! He did do it!

"We did it," he finally said.

"I didn't do anything."

"Yes you did Kim. I appreciate all your help."

"Thank you," she said. She wasn't sure how she helped but it would be cool to tell her friends that she helped on this project.

"Take off a leaf. I want to look at it under the microscope."


It took fifteen minutes to set up.

"I have to go to class now," she informed. "See you later."

"Okay," he said, staring into the eyepiece. He was so excited about the rose that he didn't look at her backside as she left.

The results were amazing. It was amazing that he couldn't find anything wrong. It looked like a normal leaf. He wondered if there would be a thinning that would make the leaf weak, but everything was as it should be. The device worked! It worked!

He became lost in his work.

"Dr. Kemp?" a girl's voice said.

"Yes," he said.

It was Charlotte from his first class.

"Is class cancelled today?" she asked.

He forgot!

"No! No!" he said. "I'll be right there."

He gave three disjointed lectures in his classes including the last one that Kim was in. He couldn't get his mind off his discovery.

When Kim returned to the lab, he was inspecting a flower petal.

"Hello, Kim," he said without looking up.

"See anything?" she asked.

"Not a thing. Isn't that wonderful?"

"I guess so," she said, unsure why it was wonderful.

He picked up on her uncertainness.

"The rose is normal. You wouldn't know it from one that took months to grow this big. It has no weaknesses or health issues. It's a normal, healthy rose. That's important."

"That's great, Doctor!" she said understanding.

"So which plant do we shoot now?" he asked.

"All of them!"

"We should do one at a time. Each plant might react differently."

"That's true."

"Pick another one," he said.

He walked over to the bench and picked up the device.

"What do you think?" she asked.

"Do you like strawberries?"

"A lot."

"Let's see if we'll have some fresh strawberries to eat tomorrow," he joked.

Charles aimed the device at the plant and fired. The only sound was the 20 second hum.

"We again wait until tomorrow," he said. "Take some statistics on the rose's growth and put it in the log."

"Sure, Doctor."

Charles wrote down readings from what he saw in the microscope while Kim took down measurements from the physical plant.

His excitement calmed and his mind turned to his usual thoughts. As Kim turned and bent around the pink rose plant, he imagined her doing that naked. He still wasn't back to normal because his thoughts would actually drift off of sex with Kim and to the device. He knew that the faster he could get data to prove the device safely worked, the sooner he could be making big money off it.

He grabbed the device and returned to the garden.

"What are you doing, Doctor?" she asked.

"I'm going to expose the grass too."

"Okay." She moved out of the way.

Charles fired at the fescue grass.

"I wished it worked on me," Kim joked.

"Your breasts are big enough," he said. A decent breast size was one of his criteria for a lab assistant.

"Not that," she said, feeling a little embarrassed. Did the doctor think she was talking about her tits? She knew she was a good size. "I wish it would work on me so I was taller."

"Oh, is that all!" he said, laughing. He turned the device toward her. "Bam! You're taller."

He fired the device. It emitted its invisible light and stopped.

"Make sure you measure yourself before you go to bed and again in the morning," he continued to joke.

Kim stood motionless with her eyes locked on him. Did something happen to her? He had a moment of panic until finally she moved. Did she just play a trick on him?

"What was that, Doctor?" she asked.
