Yuri Katahira, 42, is a married woman who was a teacher until three years ago. She was so popular that male students confessed their feelings to her, but in fact, she used to be embraced by the huge-dick, virile principal every night after school... She's grown tired of sex with her bland husband, and has been so sexless that she can't even remember the last time they had sex. As she spends her days masturbating when her husband isn't looking, memories of the time when the virile principal embraced her come back to her... This time, she has decided to appear in an adult video in search of excitement that goes beyond the sex with the virile principal...
