Today, I’m Taking Off My Ring… ~A Body That Can’t Go Back…~”. It centers on a married woman (implied by the wedding ring) who decides to remove her ring and surrender to forbidden pleasures, leading to intense sexual encounters that irreversibly change her body and mind. The plot revolves around heavy netorare (NTR/cuckoldry) themes, where the protagonist indulges in extramarital affairs, becoming addicted to the thrill and physical transformations from repeated, extreme sex acts. Expect scenarios involving cheating, corruption, mind break, bodily changes (e.g., heightened sensitivity or “trained” body), ahegao, and deep emotional/psychological descent into depravity.
Common hentai tropes here include married woman infidelity, blackmail or seduction leading to downfall, public or risky sex, and a focus on the “irreversible” corruption of a once-faithful wife. It’s a single-episode (or short series) OVA with explicit animation, voiced scenes, and no interactive elements like a visual novel.
If you’re into dark NTR with married protagonists, physical/mental breakdown, and high-intensity erotica, this is a classic fit in that subgenre. Note: This contains extreme adult content, including non-consensual elements in some similar works.
