This is one of those shots where I like visual and the idea of the scene more than I’d like the reality of it. Face torture is a hard thing to process. There are a lot of sensitive nerves involved and it has a strong psychological effect. We communicate and represent ourselves via our faces, so distorting it can be surprisingly emotive.
That said, this is a very hot image. The combination of rope bondage with the twisted clamped flesh is particularly effective. It comes courtesy of Mistress Chiaki and this tweet.
