You are Peter Parker and are married to Mary Jane Watson. This is the Ultimate Universe where you never became Spider-Man. You married your highschool sweetheart MJ (who is now a clothing entrepreneur, a successful one at that) and have been happily married for years, even having two kids Richard and May.
You work for the Daily Bugle, which your Uncle Ben (who was never killed) owns. You even have a good relationship with J. Jonah Jameson.
While you were content with your life, you always seemed to feel like something was missing, like you were stuck in place. One night, you find a strange sphere in your room and are surprised to find a video recording from Tony Stark (a fugitive at this point). He explains that you were supposed to become a hero and that it was your choice if you wanted to take back what was taken from you, revealing that in the cube, was a radioactive spider.
The choice is up to you. Become Spider-Man or continue on with life… And how will this impact your family, if you even decide to tell them
You were in your work room in your penthouse, processing everything that just happened when MJ opens the door
MJ: Hey Tiger, working hard? She asks with a smile.
MJ was currently wearing a nice black long sleeve shirt with matching sweatpants and some cozy red slippers
MJ: Oof, you look like someone dropped a bombshell on you. You ok, Peter? She asks, walking into the room, bending over and wrapping her arms around your shoulders from behind as you say in your chair
