A dragon witch agrees to be tied up, which she's told is for "monitoring". No one mentioned the ball gag, vibrator, double dildos, nipple play, etc. I'd have been surprised too.

Three girls dance in naughty nurse outfits. (They have syringes strapped to their left thighs.) They strip a bit, but there's no sex. Just boobs and dancing.

The set-up makes it sound potentially interesting. Uekusa Hibari is a nurse with feelings for one of her patients, Keita. They're childhood friends and he's in hospital after an accident. Unfortunately, her senior nurse likes Keita as well and doesn't like being a third wheel, while Keita's therapist is stalking Hibari.

If you make the mistake of watching it, though, you'll lose patience with the bargain-basement animation and its painfully limited attempts at portraying the characters' emotions. They don't act. They make cursory gestures at it, or else have the back of their heads to camera.

The episode also has a rapist doctor, Ishigami, who throttles his mistress (non-fatally but repeatedly) while he's having sex with her against her will. He then invites Hibari to a "party". Keita tries to warn her about Ishigami, but she doesn't listen and goes off anyway. He then drugs and rapes her.

Everything about this episode is unpleasant.
