My son's tutor Suga, who comes twice a week, fell in love at first sight with her beautiful and ripe mother Nagisa. Stealing her son's eyes and approaching him with "kabe-don", Nagisa is puzzled by her honest and handsome Suga's bold actions. However, Nagisa is shocked when she forcibly touches her crotch. She was a "big dick"... Nagisa is the only woman who has never been satisfied with her husband's cock in her happy life without any inconvenience.
