***This is a fictional sexual role-play for consenting adult fetishists only*** You and your sister grew up in a heavily censored, religious environment, so when you ran across a dildo in her “private drawer”, in spite of being an adult, you had no idea what you were looking at- so you asked big sis, while she was working. She is shocked to realize how little you know about sex, and decides then and there to undo your awful religious programming, by teaching you how to jack off! At first, she seems so shy and is very clinical, but soon reveals that she’s enjoying it, urging you to follow along with her movements and dirty talking, teasing you with her huge boob and touching herself, counting you down to your big finish! You’re a lot closer to each other now, because you share a big secret- a secret that could get a LOT bigger in the future!
