I'm not aware of any such fanfiction. Fanfiction usually focuses on the characters' adventures, relationships, and powers, rather than such odd combinations. It's also possible that such a concept might violate the terms of use of many fanfiction platforms as it could be inappropriate or not in line with the spirit of the original characters.
Most mainstream platforms don't allow 'lemon' (adult - themed) fanfictions. But if you're looking for non - inappropriate Spider - Man and Wasp fanfictions, you might find some interesting stories that explore their different power sets and how they complement each other. For example, there could be fanfictions where they have to work together to stop a new supervillain that is immune to their individual attacks. It's all about the creativity of the writers in the fanfiction community.
Here's a more detailed fanfiction idea. Spider - Man has been feeling a bit down lately, so the Wasp decides to cheer him up with a birthday celebration. She bakes a lemon pie from scratch, which takes her hours because she's not much of a baker. Meanwhile, Spider - Man is out on patrol, not suspecting a thing. When he gets back to the Avengers compound, he's greeted with a big 'Happy Birthday' sign and the smell of fresh lemon pie. The Wasp tells him how much she values their friendship and how he's always been there for her. They sit down, enjoy the pie, and talk about their hopes and dreams for the future. Spider - Man realizes that no matter how tough things get, he has great friends like the Wasp by his side.
A simple plot could be that it's the Wasp's birthday. Spider - Man, knowing her love for unique things, gets her a lemon - infused perfume. They then go on a rooftop adventure to celebrate, looking at the city lights while sharing stories about their first encounters.
I'm not sure if there is an existing fanfiction exactly like this. It could be a very strange and unique concept. Maybe someone out there has created a story where Spider Man and Wasp are involved in a situation related to a 'birthdaysuit' in a lemon - like, out - of - the - ordinary way. But it doesn't seem like a common or mainstream fanfiction idea.
It's possible, but I haven't come across one. The idea seems really out - there. Maybe some really creative and boundary - pushing fanfic writer might have thought about it, but it's not a common trope in the fanfiction world that combines these elements in this way.
One common theme is teamwork. Since they are both superheroes, many fanfictions focus on how they can combine their unique abilities to achieve a common goal, like saving the city from a powerful villain.
There are many great fanfiction sites where you can find such stories. Archive of Our Own (AO3) has a large collection. You can search for stories that focus on their teamwork, like them fighting a common villain. For example, there might be a story where they join forces against a new Green Goblin - like character who is causing chaos in New York. The stories usually explore their powers, how they interact with other heroes, and the development of their friendship or partnership.
One possible storyline could be Spider - Man and Wasp teaming up to stop a new super - villain who has the power to control technology. They'd have to use their combined skills, with Spider - Man's agility and web - slinging and Wasp's ability to shrink and fly, to outwit the villain.

Their powers can be combined in a fight. For instance, Spider - Man can web up enemies and then Wasp can shrink down and fly into the webbed area to deliver a powerful electric shock. Her small size allows her to get close without being easily detected while Spider - Man provides the initial restraint.
