This might take a while.

After an endless time stuck between her thighs with no more activity than a slight shift once in a while, the red light called K-T back to the lab. While he was going upstairs he could feel himself getting grabbed and set vertically on a metallic surface, his balls resting flat on the cold surface.

"Hey Emily, have you finished with... it?" he asked her, seeing his cock, still hard and pointing up, resting under the same apparatus she had first put it under.

"Ohh no, far from it. It's very important research, you can't speed it up. Do you have any new data to provide on the effects of the device on you? Anything out of the ordinary?"

K-T knew that when she was in research mode anything he would say had equal chances of shortening his ordeal or to trigger a new set of embarrassing tests. But in this situation he really wanted to cum so he was ready to do anything that had a chance to make it happen sooner.

"Well... It's my balls, when you hold the thing in a weird orientation they dangle down in a direction that doesn't match my body or that would make them clip with it if they were still on me. It feels super weird. Also when you dropped it earlier, I don't think the brain can process part of you falling down while the rest isn't moving at all. Do you think I have it back for a bit? You know, while you do something else..."

"No, the reason I just called you is because I did a lot of the diagnostics already, now I'm going to do some hands-on testing and I need feedback from the subject. Put those on your temples," she instructed him, handing him two small gel patches with electrodes on them.

K-T obeyed without questions, by now he was pretty used to his sister monitoring his vitals while testing her inventions.

Emily had some sort of wand in hand, a metal rod ending with a ball with a black plastic handle. When she got it near his cock, K-T could see a small electrical arc form between the tip and his separated genitals accompanied with a tingle.

For the next hour she poked and prodded his organ with the rods, checking the readings on her computer or asking K-T to describe what he was feeling. She also made sure to often touch his cock with her gloved hands to make sure he remained hard, but never gave him enough stimulus to cum.

At some point she picked it up and fixed the portal device on the inside of a metallic lid, storing his cock upside down in a glass jar.

"What are you doing?" K-T asked.

"I'm finished for now, at some point I'm sure a bunch of stuff will leak from it, I don't want you to make a mess everywhere." She explained, nearly interrupted by the doorbell ringing. "Can you open the door K-T? It might be the courier I was waiting for. I'll be right there."

K-T obeyed, glad that the experiments on his dick had stopped and hoping to get it back soon.

K-T opened the front door only to be met by a girl wearing the uniform of a delivery company founded by another genius that advertised being able to get packages anywhere on the globe in a matter of hours. What was weird was that she didn't seem to have a parcel with her.

"Hello, I'm here for an Emily Smith, parcel collection for priority shipping to Osaka?" said the delivery girl.

"She'll be there any minute, she sent me to open." he explained. His sister often received or sent packages to exotic places, the genius community having a lot of exchanges to make sciences advance by leaps and bounds.

His sister arrived, still only wearing underwear and an open lab coat, she was holding a tall cardboard box with a fragile label on it and another who said express delivery.

"Here's the parcel, 3 hours delivery right? Dr Nakamura is waiting for this and it is very sensitive research material." She said, giving the parcel to K-T who gave it to the delivery girl.

"Yes, 3h delivery is guaranteed even to Japan. Don't worry, we are used to handling fragile or dangerous materials. Your package is safe with us." replied the delivery girl.

She went back to her vehicle that wasn't a van but something looking like a race car and after securing the package in the trunk she drove off at a speed that was rather ludicrous for a small suburban area.

"What were you shipping?" asked K-T, curious about what else his sister could be working on.

"Well, peer review is an indispensable part of proper research and Katsumi, Dr Nakamura, from the University of Osaka, had a lot of questions about my data. She had been working on a similar project for a while and she got wildly different results. So she asked me if she could borrow my prototype. It seemed like a good idea, she'll send me her own device and we will be able to test them on a long range for a few weeks before we each send them back." said Emily.

K-T's jaw dropped. He had just given someone his cock to be sent to Japan for a few weeks. Having his sister play with his cock in her lab was already humiliating and frustrating enough, but now an unknown number of strangers would do the same. He had absolutely no idea what would happen to him. Worse he would have to pee at some point and would have no idea on how to warn these people about it.
