First thing that came to my mind is Haribo's works especially the Mad Dog. Idk, you have already read that since it's pretty popular. But anyway, that author really writes and draws characters with pretty hot sexual tensions without actually doing it.
Blue sky complex and blood bank the build up to the sexy scenes are done so good omfg
These are the first few I can think off
