Ichinatsu Tokiwa is 44 years old. She is a lone mother of two children who works at a drugstore and handles all the household chores. Every day is hectic, and her children are the center of her home. There is no room for eroticism in her life, and before she knows it, she is sexless. For the past few years, the only time she has found solace is when she devotes herself to her hobby of yoga, but as she trains not only physically but also mentally, she realizes how starved she is for sexual desire. With his thoughts cleared and his body energized by the daily training, he wanted only one thing: hot sex. Watch as her instructor-level, ultra-beautiful body accepts another man’s rod head-on and blooms into a lewd mess.
