Boo, Ton, and Koro were getting ready for another day of work for the production of pizza for their parlour. After a couple of hours of hard work, they all went to shower. The next day, they all decide to go to Sanriotown Carnival when they got their paychecks. The three piggies went to different attractions, usually in twos. On Ton and Koro's way to the water slide, Ton and Koro's clothes got wet. Ton saw Koro's overalls wet and covered his crotch and crossed his legs.

“Ton?” Koro asked. “You need to pee?”

“No.” Ton said, removing his hands and uncrossing his legs.

Koro saw Ton's bulge, noticing he was a bit aroused.

“Oh.” Koro said. “I can help you with that.”

Koro takes Ton behind a bush. He then pulls his pants down, revealing his erect curly penis. Koro started touching the tip a bit, making his brother moan lightly.

“You're really sensitive, are you?” Koro asked.

“Yes…” Ton said.

Koro then placed Ton's penis inside his mouth and started sucking it. This caused Ton's moans to continue. Eventually, Ton was squealing lightly as he slowly came in his brothers mouth.

“Feeling better?” Koro asked.

“Yeah.” Ton said.

Koro and Ton caught up with Boo at the carnival entrance. They all went home and went to their rooms. That night, Ton heard noises from Koro's room. He went to investigate, and much to his surprise, he saw Koro playing with Boo.

“Aww, Boo.” Koro said. “You're so adorable.”

Koro then proceeded to suck Boo's erect curly penis. This caused the little pig to moan loudly. Koro then stopped for a moment.

“Let's see how you cum.” Koro said.

Koro then stuck his curly hardon inside his brother's ass. He went at a medium pace and then went faster, all the while stimulating his brother's prostate. At the brink of an orgasm, Boo squealed as he came so much.

“Wow.” Koro said. “A lot came out.”

“I sure hope nobody was watching us.” Boo said.

For a moment, he looked at the door, only to see nobody there. Ton had left after Koro had stopped with the sucking. He was a bit relieved, and went back to bed.
