Incest line for Luke here, with Luke playing the big brother who used to be responsible and loving and then went through his rebellious teenage phase only to never really leave it. Generally Luke's a wreck (drinking habit, womaniser, gambling, etc.) and his parents hate him, but his lil bro used to be able to take care of him and set him back on track when things became too bad; Luke's also way different around him, kinder and sweeter and trying not to mix his bad habits with his favourite person. They were thick as thieves, close as all hell, then the younger brother left the family to pursue bigger things and without his compass Luke spiralled.
Luke's definitely felt something for his little brother for ages, always loved him but told himself not to do anything about it, things like that. But much as he wanted to resent him for leaving, when they reunite and he sees his kid brother again all grown up, it makes everything come back, which obviously leads to Luke not being able to resist any more.
I'm leaning more towards scenarios where the little brother has also felt something for Luke, but I'm willing to do dubcon leading into full consensual stuff. Preferred PB for the younger brother is Jason Bateman (no need to use those icons if you'd rather not!), but any other dude in his mid-thirties with that innocent puppy + clean look going on is totally cool.
Whether you want a smutty reunion oneshot or to play a longer line with the angst and reconciliation and fluff, I'm good with anything, but would rather keep it to threading through journals. Willing to work in supernatural/human dynamics too, where Luke's been turned into a vampire during his trysts or they come from a werewolf family or what not. A/B/O dynamics are more than welcome. Also, Luke's definitely going to top his kid brother and I'm not too into writing switches, so.
