smutty BL that's office age or characters aren't in school anymore?

I loved Doushitemo Furetakunai. Idk of its smutty enough for u but it's yaoi and they're both working adults.

ANTI P.T, man crush, the devil's temptation or On Doorstep, Midnight rain and Chongtak other works (or should I say piece of art ☆)
