Although Piper Perri and Hollie Mack have just recently become step-sisters, it didn't take them long to act like actual sisters. Hollie is an aggressor. She's the popular girl at school, she's obsessed with her street cred, and she wants everyone to know that they're all dirty. Piper sees things completely differently. She is a bright young woman who is determined to achieve the highest grades and doesn't have time for foolish bullies. She is still proficient at the game. As it happens, she is a genius. Piper senses that something is up when Hollie won't go away in peace, but Hollie wants to show her that she's not as stupid as she believes! Piper will definitely want to hear this, wow. Hollie demonstrates that she is old enough to handle the study Piper could definitely aid her with by showcasing her developing physique. After demonstrating that she is morally superior, Piper starts to believe she could play Hollie's game after noticing her gorgeous natural breasts. Until Piper gives in to her emotions, Hollie dares and begs. Hollie informs Piper that she will demonstrate a few concepts to her that she won't cover in her test. Piper displays her naivety by accepting and reveling in her step-sister's sensual touch. Curious if there was a problem between them, she gives her a kiss in return. Hollie's goal is to prove to Piper that she is capable of being both seductive and cerebral. When Hollie starts licking Piper's pussy, Piper can barely stand the sensation and sucks softly into Hollie's ravenous mouth. Soon, Piper picks up knowledge from Hollie and demonstrates to her that she is also rather mature by using her gut feelings.
