Plusle and Minun (Bad Ending)
This is a continuation of this one: https://www.furaffinity.net/view/41745469/
Squirming and dancing, the two Pokémons desperately tried to find a solution to their problem but unfortunately their bursting bladders didn’t give them much time to think. They started to burst in unison, the urine stream crashing on the front of their pull-ups spreading a sensation of warmth throughout the front of their pull-ups, the wetness indicators of their both pull-ups turning yellowish and the plus and minus symbols becoming blurry, they tried to stop it, but they only made the urine to come out faster. 
Seeing how they could do nothing they just stopped struggling and let it flow, they felt a mix of relief and embarrassment, peeing after holding it after so long felt really good but watching at their pull-ups swelling up and becoming yellowish was really embarrassing, but there was nothing they could do now.
After 3 minutes, the flow of urine had stopped, their both pull-ups were soggy and almost about to leak, it felt like wearing a wet sponge between their legs. With their both pull-ups full and feeling embarrassed, the two Pokémons headed downstairs to ask their master for a change.
Well, that’s it for this story. I feel bad for the brothers, so tomorrow I’m gonna post an alternate/good ending for this story.
