I'm in search of slash lines involving a realistic D/s relationship with strong BDSM aspects, complete with consent, trust, aftercare, maybe a few boundaries occasionally overstepped or things going wrong, both partners as proactive as each other etc. I'd really like to play this guy as an active, self-sufficient sub who isn't afraid to ask for what he wants. I've got a few plot ideas in mind, but I'd much prefer to brainstorm and see what we can scheme together. Threading and third-person/past tense, please.
