"Don't tell Mom and Dad... this is a secret..." My parents remarried and I suddenly got a new step-sister, who has a cute face but is a real slut! "You've never had sex before, have you? Shall I teach you?" With her seductive hand techniques, fierce tongue action, and developed breasts, this devilish little sister inserts in a cowgirl position with her obscene hips, contrary to her appearance! A secret act with a slutty step-sister who uses her S-class lewd techniques to get pregnant!
