Note that the monster actually did zap her in the manga, so the lightning effect's not just an orgasm depiction... maybe. (Ironically, it's hard to tell if she IS having an orgasm or not.)
F*cking Crimson Comics! The only thing worse than the waste of good talent is the flippant attitude of the artist regarding the sexual victimization of women. If there's a female you like, you can be sure than Crimson Carmine WILL have depicted them getting raped, humiliated and emotionally/mentally broken at some point!
