Plot is also important. You can't just have a series of sexual encounters without a story. Maybe there's a mystery in the pizzeria that the characters are trying to solve while also dealing with their growing feelings for each other. And don't forget to proofread for grammar and spelling to make your fanfiction polished and enjoyable to read.
First, know the original 'Five Nights at Freddy's' lore well. This will help you build on the existing world and make your fanfiction more believable. For the lemon aspect, focus on building sexual tension gradually. Don't rush into it.
Character development is crucial. Make the characters, whether it's the animatronics or the human characters, have distinct personalities. In a lemon fanfiction, their personalities should play a role in how they interact sexually. For example, a shy animatronic might be more hesitant in certain situations. Also, use vivid descriptions to set the mood, like describing the dimly lit rooms of Freddy Fazbear's Pizza place.
