Lincoln and Lisa Experiment

>after his success with Lucy and Luna Lincoln was confident that he could "Help" his other brothers
>But for that he would need more....specialized equipment
>For that, he was going to have to go to Lisa, The smartest of the Louds.
>"Hey Lisa."
>"Greetings Lincoln, what can I do for you today?" asked Lisa
>" Well Lisa, I was wondering if you could help me with an experiment."
>"An experiment you say? I never took you for the scientific type." Lisa said, surprised by his brothers request
>"What is the nature of your experiment? Nuclear? Chemical? Robotic?"
>"Biological." replied Lincoln
>"Biological you say? What kind of experiment are we talking about here?"
>"Well" Lincoln started "I wanted to see how much liquid the human bladder can handle"
>"ehhhh, I don't know Lincoln, I'm not sure if that's a-"
>"Ah well, never mind" Lincoln interrupted "I'll just ask Leni for help."
>"Leni?!" Lisa gasped "LENI HAS NO GRASP ON THE SCIENTIFIC METHOD, OR LAB WORK IN GENERAL!"
>"I once asked him to put on some gloves for safety during an experiment, So he went to his room to get his driving gloves"
>"I'll help you Lincoln, if for no other reason than to make sure things stay safe"
>"alright then" Lincoln said "Just sit here and let me get my equipment"
>Lincoln ran off to his room and came back with a small red box


>from the case, Lincoln produced a small hollow Stainless steel pile with a bulge on one end, a plastic tube, a funnel, and a jug of sterile water
>"Lincoln" said Lisa "If you want me to drink the water I can do it without this...metal straw"
>"Oh, I don't want you to drink it, That would take too long, and most of it would be absorbed and used by your body. We're going to have to be a bit more direct about this."
>"Direct?" questioned Lisa "What do you mean by Direct?"
>"Well, since swallowing the liquid would throw off the experiment, we're going to have to go through the other hole."
>"You mean my...." Lisa looked down and started to blush
>"Yup, Going through the urethra is the most direct way, it will also produce the most accurate results"
>Lisa Couldn't argue with Lincoln's logic, which was new for him
>Lincoln put on a pair of gloves and applied the lube to the rod
>He put the tip of the rod to Lisa's penis which was already erect, More out of nervousness than excitement
>"Deep breath Lisa" said Lincoln as he began to push the rod into Lisa's penis
>"Lincoln...it's starting to feel strange" said Lisa, His blushing face growing redder by the second
>"Almost there" said Lincoln in a reassuring tone
>Lisa felt a bump at the tip of his penis
>"Is it done?" asked Lisa with hope in his voice
>"Not just yet" replied Lincoln "Just need to put the bulge in, this will stop liquid from leaking out and compromising the experiment"
>"Ok, J-Just go slo-aah AAAAH!" Lisa let out a moan as his glans stretched around the ball
>"Ok" said lincoln "It's all in"
>Lincoln attached the tube to the metal rod, and the funnel to the tube.
>"So, how do you want to measure this? Grams, Cups, Ounces, Liters?" Lincoln asked Lisa jokingly
>"Ok, here comes the first cup"
>Lincoln poured a cup of water into the propped up funnel

>Lisa let out a little gasp as he felt the cold water hit his urethra
>"Feeling ok Lisa" Lincoln asked
>"Y-yeah" He replied "Feels..Feels kinda good"
>"Great!" exclaimed Lincoln "Here comes another cup!
>Lincoln poured another cup of cool water into the funnel
>The weight of the water caused it to push its way further into Lisa's untouched urethra
>"Cup number three!" Lincoln exclaimed as he poured the third cup into the funnel
>"Lincoln, I can feel the water pressing against my....uuuuuuughhhhguuuuuh"
>The water began to penetrate Lisa's bladder, it only just trickled in, but the cool sensation was an wildly different to the hot urine that usually builds up in there
>Cup four went into the funnel, the added weight caused the water to push more forcefully into Lisa's bladder
>Lucy couldn't contain his moans anymore
>each added cup made the water force its way into his bladder harder than the last
>"Cup 8, You're doing so well Lisa" Lincoln exclaimed
>Lisa's bladder was starting to bulge, you could easily see it in contrast to his flat stomach
>"L-Liiiinc, i guuuh, buuuuh"
>This feeling was getting to be a bit more than Lisa had expected, He could barely even form words anymore
>Cup 13 went in, and Lisa's bladder further expanded
>at this point, Lisa was looking pregnant
>"Lincud, It's starting to feel weird, it's..oooooooooooh uuuuuuuuuuuuuuh, aah, aaaaaah"
>Lisa's bladder was starting to push against his prostate
>It wouldn't be long now
>"Cup 16" Lincoln stated "you seem to be liking this"
>"UuuUuuuugh, Lincoln, I think... I think IiiiAAH, AAAAAAAAAAAAAAAAAAH!"
>The feeling of his bladder expanding and the pressure on his prostate was too much for Lisa, and caused him to orgasm
>"Well, that seems like enough water" Lincoln said as he got a large bucket
>"get ready Lisa, I'm gonna pull it out now" announced Lincoln "Three, two, ONE!"
>Lincoln quickly pulled the tube out of Lisa's dick, causing a stream of water and cum to flow out
>after what seemed like an eternity, Lisa had finally peed out all the water
>Lincoln looked into the bucket and pouted
>"There's cum in this bucket" he said with a fake disappointed voice "Nope, this just won't do, since we don't know how much cum you let out, the experiment is compromised."
>Lisa just lay there on the table, Bladder back to its normal size, dick still dripping water and cum
>"We'll just have to try again next week, Whadaya say Lisa?"
>"Uuuuh huuuuh" was all Lisa could reply
>"Great, Same time next week" Shouted Lincoln as he left the room
>Lisa just laid there for the next hour or so, energy spent, dick dripping
>He was looking forward to next week
