Yui is a beautiful, well-built married part-timer who has seemed down lately. She admits her marriage has become sexless, so a coworker offers to relieve her stress with a shoulder massage. Up close, her body is far too tempting; he "accidentally" strokes her shapely breasts and notices she does not resist. Once her clothes come off, kneading and sucking make her moan despite herself. She has clearly been pent up for a long time, and he is more than willing to give her a thoroughly pleasurable release.
