One of the categories this week’s release has been filed under is “complex consent”, and the consent dynamics going on in this film are indeed complex - as is the balance of power. Sarah’s the one getting spanked, bottom bare and school shoes kicking in the air, but she could blow this whole thing wide open at any moment. She’s not even getting anything material out of the deal; she’s only here as a favour to a friend.

She stares directly at said friend the whole time she’s having her backside tanned with a hairbrush. There’s pain in her expression - after all, she’s having her backside tanned with a hairbrush! - but I reckon there’s an element of challenge to it, too. “You’ll owe me for this one, John.”
