Basically, Nicole (Gumball's mom) had just finished folding up laundry and was heading to put it all away. When she got outside of Gumball's room, she heard him moaning and grunting. She opened the door and caught him sitting on the edge of his bed with his pants down and one hand on his privates. He screamed and yelled at her to get out. She panicked, apologized, ran out and pulled the door shut behind her. Leaning back against the door, she tried to process what she just saw. "Was he just- No, he's not old enough for that... is he?"

She went back downstairs and tried to think about what to do. But not long afterwards, she heard a door open upstairs. She peeked around the corner and saw him heading into the bathroom, carrying a tube of something. She decided to go to his room and check things out. The first thing she noticed was the funky scent in the air. Then there was the long white stain on his bedsheets. In the wastebasket, she saw two crumpled up tissues. She picked one out of the trash and checked it out; white and gooey on the inside. Just then, Gumball came back and startled her. She made up an excuse that she just came back to get the clothes basket, then bolted out the door.

One last thing she needed to check: What was he carrying earlier? She went to the bathroom and looked in the medicine cabinet. There were several tubes in there: Toothpaste, rash cream... and lubricant. Everything was adding up. She couldn't believe that her little Gummypuss was doing something so... adult.

So since he was getting to "that age," she felt like it was about time that someone gave him "the talk." I forget a lot of the details of this part of the story, but basically she confronts Richard (Gumball's dad) and convinces him that he needs to be the one to do it.

So Richard goes up and and tells Gumball that they need to have a chat. He starts going into stuff about the birds and the bees, and that he doesn't need to feel ashamed about what he was doing earlier because lots of guys do it. Gumball is confused and has no idea what he's talking about. "Uhh, lots of guys use rash cream?"

So the story flashes back to earlier in the day, with Gumball and Darwin (His brother/pet fish) walking home from the park. Darwin is his usual cheerful self, while Gumball looks like he's in a lot of pain. Darwin asks what's up with him, so Gumball lists off a bunch of bad things that happened to him at the park, and finishes it off by saying he got sand in his pants, and he's pretty sure it's giving him a rash.

They make it back home and Gumball walks upstairs to the bathroom while his mom is folding clothes in the living room. He hops up on the counter and looks in the medicine cabinet. Toothpaste, lubricant... Ah, rash cream! He grabs it and heads back to his room, then drops his pants and sits on the edge of the bed. He pops the top open on the tube and tries to squeeze some cream into his hand, but nothing comes out. He tries picking at the dried-up bit at the end while squeezing, which causes a bunch of cream to shoot out of it and land on his sheets. The cream smells kind of funky, but he just grabs some tissues and tries to wipe it up. Finally, he squirts some into his hand and starts rubbing between his legs. But as soon as he makes contact, it stings. "Aah! Ooh, oww, rrgh! That burns!" He keeps rubbing it in when his door suddenly swings open. "AAAH! MOM! GET OUT!"

And so we come back to the present, where Richard now understands what happened. He figures that this gives him an excuse to not have "the talk", so he lets Nicole know after he heads out of Gumball's room. She's relieved that her Gummypuss gets to be her baby just a little while longer. But, she realizes that she forgot to give him his clean clothes, so she heads back up to give them to him. When she opens the door, Gumball is sitting at the computer with his pants around his ankles, watching porn. "AAAH! MOM!"
