I'm on a TVtropes Batman-related crusade and having a lot of fun (and yes, avoiding my scarier plot bunnies. I want to write the fic, but it scares me. I'm not being hyperbolic.) and I came across the trope "Rape Is Ok When It Is Female On Men". And what do you know, of course one of the examples was Nightwing's rape by Tarantula.
(
except it's not depicted as okay. )
