Stewie Griffin has always loved Finding Nemo ever since the creation of the film. He had always imagined the gratitude he would feel to whatever deity he worshipped if he were to meet the actors in the film. One day, he was blessed with running into Nemo on the strip. After chatting it up for a while, Nemo said,
"Yo… doooooooooood… HMU SOMETIME. WE CAN TURN UP IN THE ANEMONE!", to which Stewie responded,
"Of course, I would love to… hit you up… Give me the numerical digits that link to your cellular device and I'll call you".
Stewie was not impressed with the intelligence of the yearling Nemo. But, as the cast consisted of his idols, he called anyway. Nemo informed him of a partayyy with all of the cast member that Stewie should for sure attend. Stewie was overjoyed with the thought of meeting the fish of his dreams. He proceeded to clench his large-for-a-two year-old boy dick. He screamed and moaned with the thought of stroking Marlin's reproductive fins. He fell asleep to this action and woke up and had to get ready for his big day with the cast. He put on the clothes that were easiest to take off to prepare himself for Marlin's adult male fish body. He didn't even wear a diaper.
He arrived at the party with full intention of introducing himself to Marlin and becoming Marlin's new whore. Stewie gazed at Marlin from across the room, but before he could reach him, an angel fish came over and acted as if Marlin was hers. Stewie would show her.
He waited in the women's bathroom for her to leave Marlin's side. As soon as she did, Stewie lay in wait. He stabbed her 37 times until he was sure she was dead. He couldn't have any distractions between him and his love, Marlin.
After leaving the Angel Fish dead, Stewie proceeded to find Marlin and introduced himself with confidence. Marlin was left unimpressed, much to the displeasement of Stewie. Stewie waited until everyone had left Marlin's home and proceeded to get himself naked in Marlin's bed.
When Marlin came to bed that night, Stewie lay unnoticed. Marlin finally lay down on his bed and Stewie shrunk to fish size. He mounted Marlin and proceeded to place his baby dick in Marlin's anal fins similar to the lips of a human female. Marlin began to moan and was enjoying himself. Marlin climaxed and they finished with Marlin giving Stewie a BJ and swallowing like the real fish he was. After they finished, Marlin could not believe he had just had ravenous sex with the little boy he had met at his dinner party. He said,
"Wow, you're more of a man than any child I have ever fucked".
