There are also some Tumblr blogs dedicated to fanfiction. Try searching for tags like 'Peter Parker Tony Stark fanfic' and then look for the ones that might involve Peter crying. However, Tumblr's search can be a bit tricky sometimes. But it's still a good place to start exploring different takes on their relationship in fanfiction.
One popular fanfiction site is Archive of Our Own (AO3). You can go there and search for 'Peter Parker crying over Tony Stark' to find relevant stories. There are likely many works that explore the emotional bond between them and scenarios where Peter might be crying over Tony's death or other significant events in their relationship.
Fanfiction.net could also be a source. Although the interface might not be as modern as AO3, it has a large collection of fanfictions. Search for the specific theme 'Peter Parker crying over Tony Stark' and you might come across some hidden gems. Some stories might focus on the aftermath of 'Endgame' where Peter is dealing with Tony's sacrifice and thus could be in a state of crying.
The theme of legacy is often present too. Peter might be crying while thinking about how to carry on Tony's legacy. He may feel the weight of living up to Tony's name and the expectations that come with it. Fanfictions may delve into Peter's internal struggle as he tries to figure out how to be the hero Tony believed he could be, all while dealing with his own emotions.
One possible scenario in such a fanfiction could be that Peter is crying because he misses Tony Stark after his death. Tony was like a mentor to Peter, and his absence leaves a huge void. Peter might be in the Avengers compound, looking at old photos or mementos of Tony, and the memories make him break down in tears.
One possible scenario in a fanfiction could be that Peter Parker is trying to hide his emotions from Tony Stark. Maybe he's been through a tough situation at school, like being bullied, but he doesn't want to seem weak in front of his mentor. Tony, on the other hand, has his own issues with showing vulnerability. He's always been the strong, confident Iron Man. But perhaps he starts to notice Peter's struggle and tries to open up about his own past traumas to encourage Peter to let it all out.
A reason could be that Peter is reminded of Tony's last words to him. Those words were full of hope and trust in Peter. When Peter reflects on them, he is overcome with emotion and starts to cry as he feels the weight of Tony's expectations.
I don't have a particular fanfiction to recommend for this pairing. But when you search on fanfiction platforms, look for ones with high ratings and lots of reviews. Those are more likely to be well - written. Also, you can join fanfiction communities and ask other fans if they know of any good ones with this theme.

There are quite a few. You can check out Archive of Our Own (AO3). There are many fanfictions exploring this dynamic. Some focus on Tony seeing Peter as a protege and becoming overly protective and obsessed in a father - figure kind of way. He might be constantly worried about Peter's safety during his superhero activities and invest a great deal of time and resources in training and guiding him.
The relationship can start out a bit rocky in some fanfictions. Tony may be initially dismissive of Peter as just a kid. But as Peter shows his capabilities, Tony starts to take him more seriously. They then start to bond over their love for science and technology. Peter is eager to learn from Tony, and Tony enjoys teaching Peter new things. This mutual exchange helps their relationship grow from a mentor - mentee one to a true friendship.
The fanfiction could start with their individual backstories that led to this trouble crying. Tony's past with his parents and his journey as a superhero has made him suppress his emotions. Peter, growing up without a father figure for a long time, has learned to be tough. As they work together more often, small incidents start to crack their emotional walls. For example, a kind word from a civilian they saved makes Peter's eyes water a bit, but he quickly holds it back. Tony notices and it makes him reflect on his own emotional state.
