Saki Ikeda, 37, is a science teacher. Her husband, 15 years her senior, is also a university professor. Surprisingly, Saki was a former student of her husband's. Just as she married her husband as a former student, Saki sometimes finds herself excited about her student. The reason she occasionally indulges in such fantasies is due to her sexless marriage with her husband. What a bad professor to be in a sexless relationship with a student 15 years younger than her... Even though her husband is over 50, it's a sin to leave a slender beauty like Saki alone. Saki has her own sexual desires, so it's understandable that masturbating when her husband isn't looking isn't enough. Let's have her relieve her sexual frustration by having a professional actor cheat on her. She strips in public for the first time while being filmed, then masturbates with her legs spread wide... It seems that Saki is excited by this stimulating experience. It's an irresistible video of the graceful Saki being thrusted powerfully by the male actor, especially in a cuckold role. Seeing Saki smiling and shaking her hips with pleasure makes you feel both lewd and happy.
