Step-Sister reads erotica and gets Horny for Big Step-Brother POV

Your step-sister is sneakily reading some cheesy erotica she printed off when you catch her. She is shy at first, but you insist on hearing a reading-- you’ve gotta make sure it’s appropriate for your little step-sister, after all. As she reads, she gets more and more wrapped up in the portrayal of these characters. Then, hesitating at first, she begins to touch you. You try to protest, but she is beautiful and you are both too horny now to resist the contact you both crave. Fantasy overtakes you both as you tumble into forbidden lust.
