K-T finds himself in hot waters.

An hour and a half later, K-T couldn't hold it any longer, so he went to Emily to ask her if he could pee without the risk of splashing someone in the face.

"Let me check, yes. The parcel is still in transit and the jar is sealed, there's no risk of your pee getting on anyone else." She explained.

K-T didn't like the no one else part of it but he couldn't hold it any more. He turned around and out of habit tried to go to the bathroom.

"Where are you going?" she asked him.

"To the bathroom, I told you I have to pee." he replied without thinking.

"Imbecile. Your penis isn't in your pants, it's not even on the same continent. What do you need toilets for? It's just like when we were on the highway and mom made you pee in a bottle. You can do it anywhere." She ranted.

"Oh, I forgot about that." he answered.

"So, what are you waiting for? I thought you couldn't hold anymore." She taunted him.

"You mean here?"

"Yes, here! It's not like I can see anything. Your dick is in a jar in a closed box on a plane on the other side of the globe. Come on."

K-T was anxious. Not only did he have to overcome a full childhood of training not to pee his pants and do it on purpose, but he had to do it in front of his sister. It took a bit of effort to do so, especially with a huge erection, but after a few seconds he managed to let go and he could feel the pressure in his blade recede.

Soon he realized that this plan was less than foolproof. The jar his sister had used was almost exactly the right size to contain his dick. The lid fitted the portal device perfectly and with K-T being so big and so erect it was a snug fit inside of the jar. The tip of his dick reached maybe two inches from the bottom and there was barely an inch of space between his dick and the sides of the jar. Space filled by his balls for the upper third of the jar.

As he relieved his bladder, the tip of his dick was quickly submerged in warm pee and it raised along his shaft until even his balls were dipping in it. It was a hot day and K-T had many drinks, worse he hadn't used the bathroom since he woke up when Emily called him for this experiment.

"Emily! The jar is getting full! Do something!" he screamed in panic. He had stopped himself from peeing further but he couldn't feel almost all of what was beyond the portal being underwater.

"Dimwit, stop peeing. The jar is sealed but the portal device isn't airtight. If you fill it too much the overflow will drip on the ground here. Go back to your room and don't pee anymore. I'll call Katsumi to tell her to drain the jar as soon as it arrives." She scolded him.

K-T left the lab and walked back to his room in the basement. It wasn't his fault his sister confiscated his dick and sent it away without even thinking about the fact he might need to pee. But he was living here rent free and got some money (not that much) for helping her in her experiments.

Masturbating was still off limits and he didn't feel like playing video games. The feeling of having his junk floating in lukewarm pee was too distracting. If the delivery company was telling the truth the package would soon reach its destination and the jar would be emptied, making him free to fully relieve himself.

He got lost in thoughts of what the Japanese genius girl wanted to do with his dick that she couldn't achieve with a blank portal device, but soon realized that his sister either did not think of inconvenience for him to be separated from his genitals for so long or did it on purpose to mess with him.

His train of thoughts was cut short by the door bell ringing again. K-T got up to open the door, but he was surprised that it wasn't yet another package or courrier for his sister waiting for him.
