Warning: This is the first fetish chapter. It involves urophillia (the pee fetish) or "Omorashi" if you're an absolute fucking weeb.
Plot: Nutty drinks a lot of beverages before Sweetheart shows up and will be forced to hold it in.

The day was still very hot, so Nutty thought of drinking a lot of fruit punch and soda. Once he was all cooled down and hydrated, Nutty sat down on his sofa watching Cake Wars. (Star Wars but with cake. Yes I know Cake Wars is a real show.) Right after Emperor Red Velvetine commanded the execution of their 66th order at the bakery they were at, Nutty felt a sensation in his body. What he drank went straight through him and he now really had to pee.
As Nutty was about to arrive to his bathroom door, Sweetheart knocked on his door. Nutty didn't want to miss out on sex, so he bolted for the door. Trying to make himself presentable, Nutty had to keep his legs straight rather than crossing them. As they went to his room, the sky became cloudier. Soon enough, it was raining.
This only made it worse for Nutty. He was about to excuse himself and go to the bathroom, but Sweetheart's nude body stopped that. Nutty couldn't go with a boner, so he decided to just bare with it. If not for his overflowed bladder, Nutty would last for a pretty decent time. Nutty's dick was starting to leak with urine already, so he knew it wouldn't bee too long.
Sweetheart and Nutty's sexual intercourse caused so much ruckus, a soda can nearby Nutty used as toothpaste tipped over, spilling, growing the urge to pee. He tried to pee in Sweet's vagina, but his erection wouldn't let him do that.
As a last resort, Nutty would try his best to cum and then make it to the bathroom. He came a few moments later, but he had that post-orgasm "have to pee" feeling and lost control. Sweetheart was surprised at what happened, but she also used it as an opportunity to drink his pee. Not too much, only enough to show she had urophilia. Sweetheart then decided to pee as well. The two then lay there on the bed, peeing out rivers.
Once both were done peeing, sweetheart got out of bed and said bye to Nutty. After that experience, Nutty decided to never use a toilet again. It was that fun.
