Prompt: Steve and Tony, the adoptive parents of Peter Parker, try to patch together their relationship after his death.
Bonus Point: Steve tries to mentor Miles Morales while Tony resents Miles for being the new Spider-Man.
Universe: Avengers or Ultimates
Prompt: Steve turns back to being his sickly frail self and turning the people around him away, all but Tony. Even with this transformation (maybe Loki was the cause? Up to writer!) they begin to have a romance and Steve acts out the submissive part due to his size, but when the spell wears off, he still feels like it.
Bonus Point: NSFW content when he turns back to normal Cap.
