I know that in the first chapter Clint has sex with someone not sure if it's Bruce, Steve or Thor and Tony sees the bruises on his wrists and makes a vulgar comment and Clint gets embarrassed, the person he had sex with gets worried that he hurt Clint. Clint makes a comment about its fine and I think walks out of the room. I think Natasha tells them that Clint likes it. Eventually clint and the person enter a BDSM relationship.
Hope someone can help me
