Ai, who previously worked as a cabin attendant for a major airline, has been married for five years and is now approaching her 30th birthday. She exudes a refined aura and is a young wife. Her husband is an elite employee at a major advertising agency, leading an incredibly busy life. Because of this, he sometimes travels overseas for business trips and doesn't return home for days. Ai, who is constantly at home, is filled with anxiety, wondering if something is going to happen. This gradually builds up stress... "I want to release that pent-up stress..." This is one of the reasons she considered appearing in an adult video. Suppressing her desire to see this beautiful and refined woman naked, she asks to see her masturbate first, and she begins shyly. At first, she doesn't moan, perhaps due to nervousness at being watched, but as time passes, she gradually begins to let out erotic sounds. Her erotic voice is both refined and elegant. When she is blindfolded and her clothes are removed, beautiful large breasts are revealed... As she continues to perform cunnilingus on Ai's pussy and plays with it with a toy, she moans even more loudly, perhaps because she is deprived of her vision. When her enlarged penis is presented in front of her, she moans with delight while still blindfolded, and carefully licks it all over to serve him. Love juices also drip from her private parts, as if to say, "Please put it in...". When she inserts it into her vagina in response to his request, she moans, "It's so big!! Ahh...", expressing her joy with her whole body and accepting the pleasure. Ai is first class in every way, from her voice to her gestures, facial expressions, and body, and she shows us her liberated sexual desire! A refined, mature eroticism...
