The car crash I couldnt look away from: Metamorphosis/Emergence... 177013, whatever you call it... fuck. No. Just no.
The one I feel weird to have busted a nut to: Aisei Tenshi Love Mary (The Archangel of Love, Love Mary). Picture Madoka Magika grown up in reality but with similar monsters. But Madoka gets caught by the villainess, then is subsequently tentacle raped and eventually after the villianess goes all out on Mary... brainwashes her into feeding her soldiers to her army and new succubus-like entities from her friends that are also magical girls and one of the squad is a boy... and he gets the full gender conversion/feminization deal too...
yeah... i regret nothing.
