Yurina Yagi, 29, wears a sparkling ring on the ● finger of her left hand. Her husband is a well-known calligrapher, and while he runs a calligraphy school, he also holds his own calligraphy exhibitions. Yurina is a student at her husband's calligraphy school, where they met and began dating. They have been married for five years. Their marriage is going smoothly, and they had sex a week ago, so they are not sexless. So why did Yurina appear in an adult video? It turns out her husband is a huge adult video enthusiast, and his abnormal sexual desire to "see his wife in an adult video" led him to appear in one. Perhaps it was because of this or nervousness, but her expression seems anxious. To ease her tension, he caresses her plump buttocks and has her get on all fours, where he applies a vibrator. Yurina tries to hold back her voice out of embarrassment, but as the stimulation gradually increases, she can't resist, her expression melting and her moans escaping. When he pinches her nipples, which are her erogenous zones, and applies a vibrator to her, she writhes in pleasure. At first, Yurina is quiet, but the actor's techniques drive her crazy and she climaxes again and again. Yurina literally goes out of her way to satisfy her husband's sexual preferences, and it seems he was completely satisfied.
