I'm Not Even Interested in Him, but He Made Me Cum a Million Times Ayumi Miura

Ayumi Miura is a married woman who finds herself in a situation where she is pursued by another man. This other man is aggressive in his pursuit, telling her that her husband's cock is not good for her and offering himself as a better alternative. As the story unfolds, Ayumi engages in sexual acts with this man, including oral sex and intercourse, despite initially expressing reluctance and discomfort. The central kink of this movie appears to be the theme of a cheating wife, with Ayumi's infidelity and her desire for satisfaction outside of her marriage being key elements.
