I reeeeeally like bondage/kink artwork. Last time I posted any it was exclusively Joe T's work which is amazing, but there are tons of artists out there. A lot of them have, in addition to a visual style, a very specific style of play that goes on in the scenes. There's one artist who comes to mind where almost every piece he puts out is essentially about a "boy factory" where men are systemically turned into slaves and kept captive, which is pretty hot. At any rate, enjoy!
