I don't really care if its during earlier seasons, if Steve and Nancy never broke up or they got back together in season 4.
Steve starts cheating on Nancy with Eddie. And Eddie loves it, sure he'd love to have Steve to himself, to come home to and wake up to every morning. But the taboo of cheating is so hot. Steve's hot and Eddie is a weak man.
+ if cheating is featured heavily in their dirty talk ("I bet Nancy's strapon doesn't feel this good" or "Do you think of me when you're fucking her? Its the only way you can get off with her, isn't it?" ++ emotional turmoil of Steve asking him to not leave marks, and Eddie wanting to paint his skin like a canvas.
