Three Little Spiders

Toby, Andrew, and Holland are triplets of Richard and Mary Parker. When they were little, their parents died in a plane and were under the care of their uncle Ben and aunt May until their uncle died as well. The rest of the story is pretty much the same but with minor differences.

Tony is Iron Man and part of the few remaining Avengers that weren't rogue. When Fury got word of a vigilante group called the Web-Warriors, he gives the billionaire orders to either lock them up or convince them to join the Avengers.

When the Parker triplets end up as orphans after their aunt died of breast cancer, they found themselves adopted by their mentor. Let's see if they can manage being the Web-Warriors and being the Princes of Stark Industries at the same time.

Multiple shippings involved and I'm too lazy to tell you which are included. This takes place in an alternate timeline where Steve told Tony about Bucky and the brainwashing instead of saying nothing so Civil War ended differently.

Warning: Bad summary, long chapters, and slow updates. You've been warned.
