My sweet 18 year old stepdaughter is a terrible nymphomaniac

Imagine you have a sweet stepdaughter who just turned 18, and you’ re home alone. You remember that a few days ago, while cleaning her room, you found several porn magazines: your stepdaughter isn’ t as innocent as she used to be. One afternoon, you realize she’ s flirting with you while you’ re alone, but you ignore it because you still see her differently; besides, you have to set a good example as the good stepfather that you are. The temptation is so strong that you dare to play along; after all, what’ s the worst that could happen? She’ s your stepdaughter, she’ s of legal age, and she’ s eager to learn about sex. Hours later, when you go up to her room to tell her to come down for dinner, you see her in a little dress that accentuates her perfectly round and firm little butt. You think twice, but in the end you give in and start touching her, hoping she won’ t notice.
