I can't stop 'kissing...' The vulgar kisses of a career woman. Yui-san, who works for an underwear manufacturer, exposes her sensitive body, trembling and reaching climax as her mature lips are taken by an actor while being fondled in a moving car. In the filming studio, her lewd lips and long tongue cover M's face, nipples, and penis with saliva, leading to ejaculation through licking and handjob. A total of four episodes, 120 minutes recorded, filled with vulgar kisses.
