Saori Yoshinaga, who has a bright smile and a plump flesh, appears in the agony series! A mysterious woman appears during her stakeout, and I, a secret investigator, am perplexed by the glimpses of her breasts and buttocks. In fact, she is Saori, a newcomer, and they form a duo and proceed with the investigation... She urinates because she's so nervous, searches for the binoculars she dropped with her butt exposed, and gives a naughty massage.
