Maihama Meru-san, a beautiful mature woman, has come for a negotiation to sell lingerie. It seems she often sells lingerie and came after seeing a recruitment advertisement. To start with, she is asked to change into her lingerie for a check, revealing her voluminous and impressive large breasts! She is then persuaded that lingerie with stains fetches a higher price, and with that encouragement, she helps create stains on her panties by playing with her vagina using her fingers and an electric massager! Faced with Meru-san's magnificent large breasts, it would be a waste not to enjoy them, so she is told about a method to receive even more compensation, which she readily agrees to! Once the arousal switch is turned on, she quickly transforms into a lewd woman suddenly craving a penis. The true form of the mature woman with large breasts, writhing in ecstasy multiple times, is captured.
