Hoya and Sven were browsing the web looking for a way to make a little extra money. They came across an ad from a research facility looking for volunteers. The details in the ad were ambiguous, just referring to some kind of bladder pressure study. While the details were sketchy the pay was too good not to at least check into it, so they applied. They soon had a reply with an appointment.
When Hoya and Sven arrived at the research facility they were welcomed by one of the researchers. The light gray furred wolf escorted them to an interview room. He asked them to sit at the table and wait while he checked if the lab was prepared for them. The table had all sorts of refreshments and he welcomed them to consume as much as they liked. Hoya preferred sweets and went straight for the cookies, while Sven was thirsty and went for the juices.
About half an hour later the two had consumed most of the food and drink and were starting to think the wolf had forgotten about them.
"Sorry for the wait" the wolf said entering the room. "I’m glad you enjoyed the snacks. The lab is prepared, please follow me" exiting into a halfway corridor. The two volunteers followed behind him.
Now that Sven was standing all that juice he had drunk was wanting out. "Before we begin, can you show me to the bathroom?"
"In a second" the wolf replied, "We need to go through this room first."
The wolf opened the door revealing a bare empty room. The metal floor and walls and the dim fluorescent lights overhead gave it an industrial feel. Several cameras were placed in each corner keeping every inch of it in view for recording.
The wolf stopped in the center of the room and said "Please take off all your clothes so we can begin."
As the two stripped Sven said "I think I have to go to the toilet first".
"No you won't have to" replied the wolf.
"What, will this experiment be over quickly?" asked Hoya, but the wolf didn’t answer.
The wolf watched as behind the pair of volunteers a panel of the wall silently slid open and several figures emerged. Suddenly strong hands grab both shoulders of the two, and they were surprised as several muscular canines pushed both towards a wall where they were forced onto the floor.
The canines stripped them of the rest of their clothes leaving the pair fully naked. They then bound their limbs tightly and positioned them with their hips sticking out. Once they were positioned and secured they watched the canines leave through the opening that hadn’t been there before, and the wall slid shut.
Hearing the wolf approach their attention turned back to him. The wolf crouched down next to Sven holding a clear plastic tube. "Sorry I can’t lube the tube, we can’t have other liquids interfering with the experiment" The wolf grabbed the otter's penis and pushed the tube inside his urethra causing him to squeak.
"Wh, what are you doing?" Sven asked.
The wolf just grinned, "your turn bunny".
With the other end of the tube with his left paw he grabbed Hoya’s penis with his right. Hoya watched the other end of the tube slide into him. He then pressed the two penises together until they touched in the middle and none of the tube was exposed.
"This tube is not a catheter." The wolf smiled. "It's much too short to reach your bladder since we are interested in more than just the pressure urine can exert. We are almost ready to start the tests, just one more preparation to ensure we have a tight seal" the wolf said and held up a needle and thread.
Sven and Hoya shuddered imagining what would happen next.
"The downside of this short tube is it's easily pulled out. So I’ll have to stitch your foreskins together. Don't worry it will not hurt."
"How do you know!" Hoya shouted.
The wolf didn't answer at first, then said "well it won’t hurt for me" and stitched both foreskins thoroughly. "Excellent, now we have a tight seal perfect for our pressure tests.
With the ordeal of the tube over Sven again noticed how full his bladder felt. He turned to Hoya with a worried voice. "Ah, I really have to pee!"
"Then let it go." Said the wolf.
"No, if I do that my pee will..."
The Wolf grinned "Don't worry about your friend, because soon the rabbit will have to do the same to you."
Hoya looked at Sven and though his expression was worried he gave the otter a nod of permission. Sven carefully released his bladder trying to keep the flow slow, but soon the need to pee took over and it gushed out. Hoya felt the pressure quickly build as Sven's warm urine ran through the tube and up into his bladder. The feeling of it filling and bloating his bladder made all his fur bristle.
The wolf waited patiently until Sven’s face showed his relief.
"Ok then" the wolf said, "Let's try another type of liquid. Rabbit, are you prepared?"
The wolf grabbed both the otter’s and bunny’s penis and began to gently stroke them.
"Wha, why did you not ask me?" Sven said.
"Oh, can you cum faster than him?" asked the wolf.
"B, but..." Sven said, "You're fapping me too."
The wolf continued to expertly stoke the two fully-erect stitched together penises. His strokes were meant to bring the two to the edge of cumming but not enough to cum, working them up to a huge release.
Hoya felt his prostate filling up and whispered to Sven "I think I am close, I don’t know how much longer I can hold it".
"Good," the wolf said, "Let it go."
"I... won't... cum..." stammered Hoya.
"Too bad, then I guess the otter will. Lets see if you can hold his seed too". The wolf said with a smile that became a sneer.
Sven glared at the wolf and said to Hoya, "don't hold back, I can handle it."
"No!" exclaimed his friend.
"Please, I already hurt you, don't make me do so again. You must cum before I do!"
"But... but..."
Sven looked at Hoya with desperate eyes, "Please hurry... I can't hold it back much longer."
Hoya gave into his friend's wishes and after a few more strokes released his seed.
Sven felt a hot pulse surge inside him but instead of entering his bladder it filled his already bloated prostate. Each spurt of Hoya's cum caused his whole body to shudder. After the 5th pulse, Sven finally lost his control. Regardless of Sven’s will, his prostate pushed back Hoya’s cum with his own violently. It was the 6th pulse. After that the odd number every time was Hoya to Sven and the even number was Sven to Hoya. The wolf carefully watched both bladder’s pressure gauges with his mobile phone.
Once that was done the pair simply lay there sweaty from the exertion, moaning from their overfilled parts and completely exhausted.
"Excellent work!" the wolf said, He wrapped a vibrator over both their penises.
"Now it’s finished." Hoya said, "Cut the thread and let us go."
"Hm?" The wolf said, "The experiment is not done yet. You were assigned a 24 hours session and now just one hour has passed."
The wolf was gone, the two volunteers, or victims remained alone to rest in silence.
