One day, Po and Tigress were in a bedroom somewhere having sexual intercourse. Meanwhile, outside the building they were in, there were two chicken children (chickdren?) playing a simple game, because that's more interesting.

"I win!" said one of the children.

"No fair, you cheated!" said the other.

The two children argued back and forth. They were about to get into a cockfight when they heard the scream of a female tiger in the building behind them. And they ran; They ran so far away.

…

…

Three months later, Tigress could be seen walking in a meadow. Viper was there too. The snake noticed a slight bump in the tiger's belly.

"It seems you've put on weight…" said Viper.

"Actually it's worse," Tigress said, "I'm pregnant with Po's child."

"WHAT?" shrieked Viper, "How did this happen?"

"The condom he was using broke. I just wish I could get rid of the coming spawn, but society is cruel, so I can't."

"You know, I may be able to help you…"

Tigress stared wide-eyed at Viper. "How? You have to be joking around!"

Viper then put her lips to Tigress's ear and whispered her idea.

"WHAT?" Tigress growled, "Let me get this straight, you want to crawl up my snatch into my womb and eat the baby from within me?"

Viper blushed.

Tigress assessed her options, as gross as it sounded, the sooner she was rid of the fetus, the sooner she could get back to doing kung-fu with the Furious Five.

"Fine." Tigress said in defeat. She pulled off her pants and underwear and sat down on the ground with her legs spread apart. Viper started to enter Tigress's vagina.

As she watched the head of her friend disappear down her snatch, Tigress wondered how this would work out. She then felt a sting of pleasure.

"Umph," she moaned.

"Did I brush against your G-spot? pardon me!" Viper said from within, "It's a bit cramped in here. Getting through your cervical canal will require a tight squeeze."

Tigress saw Viper's scaly body wiggle as the snake burrowed into her cervix. After some time, Viper suddenly stopped wiggling.

"Viper, you okay?" asked Tigress.

"Yeah. I just made it into your womb," Viper said, "Eww, that is one ugly fetus! Looks like a purple dragon with four wings too many! You sure Po was the one you did it with?"

"Yeah?"

"Well, I already came this far, so I'm going to chow down. Remind me to spit the fetus out in a fire once we're done; This could be an antichrist or something."

Tigress felt her womb expand as Viper presumably closed her jaws around the fetus. she felt something pull within, and then a wave of pain as if the thing being pulled was ripped away. There was a bit of silence for a while.

"I've successfully eaten the fetus!" Viper said proudly through Tigress's body tissue.

"Finally," Tigress said.

"Small problem though… I can't seem to get out."

The tiger huffed. "Well that's just great. How will we explain this to our master, Po, and Crane?"

"Now's not the time to give up. Try pulling me. It may trigger your body's natural labor mechanism."

Tigress followed Viper's suggestion and pulled the snake tail that was hanging out of her pussy. And it worked! For lack of better terms, Tigress gave birth to Viper.

"Okay, I'll call that a successful treatment," said Viper, laying on her back, "Let's pretend what happened never did."

"I was scared," Tigress said as she put her underwear and pants back on, "but I'm so glad you helped me with this. Thank you."

"No problem," Viper said. The two then parted ways.
