None of them are explicit and the story lines are quite good. Sorry I didn't recommend more, these are just the ones that popped into my head. Hope you enjoy~

Thanks a bunch guys! I found a few I still haven't read!

I'm currently reading this one. It's ongoing, but it's cathartic, and probably the closest you'll get.
