This boy's older half-sister has always made it a point to care for him and give him the best advice for his life. Now he has reached full sexual maturity and she doesn't want him to make a fool of himself when he has his first experience with a girl. She decides it's time to train him properly to prevent him from making a fool of himself in intimacy. And although her methods could be considered taboo, I'm sure the boy will arrive more than ready for his first fuck (and handjob).
