Safada, the elder of the two Brazilian sisters, can't stand the thought of her little sister being with anyone else. So, when she finds her masturbating, she decides to join in, teaching her inexperienced sibling a lesson in pleasure. Safada guides her sister's hand, showing her how to touch herself, then takes over, fingering her sister's tight pussy until she squirms with delight. The sisters soon graduate to toys, filling each other's holes, their moans echoing through their apartment as they indulge in their forbidden gozou.
