This is a work specializing in showing the ass and anus. But just before the end, it was rejected for emphasizing the ass… but since we can't back out now, we forcefully shoot even if she's reluctant! She tries to hide her anus, reluctantly spreads her ass, hates close-up shots of her ass, and is forcefully shot in detail… it ended up becoming incredibly erotic. 'I hate big asses' (her words) It seems like a complex, but from an AV perspective, it's the best!
