A shocking experience as a private tutor for two high school sisters. I practice kissing with the younger sister, who has just started to become interested in sex. The steps to adulthood continue, and we play sex with her small breasts. Then I penetrate her without any resistance. The older sister, who was watching from behind the scenes, didn't want to be left behind, so she begged me to teach her sex. I secretly put an aphrodisiac in my mouth and taught her how to kiss, and the shy older sister transformed into a dirty pervert.
