As much as I love consentacles, I wish there was more where the girl is consenting but the monster is nonsentient/nonsapient. I do like the "the tentacles are my boyfriend" stuff, but "this is just a thing acting on instinct, it wouldn't rape me any differently if I consented or not, and I want it to make me it's seedbed" seems so much hotter for some reason.

Or even better, lesbians letting themselves be raped by a tentacle pit together as a convoluted sex toy.
