Hot lesbian love with my stepsister.

Their parents had met when they were 10 years old, at first they were not the best of friends, they actually hated each other. One thought she would steal from her mother and the other the same with her father. However, something changed when they both became teenagers and their hormones drove them crazy. The first time one caught the other touching herself and asked her to teach her, so they got into this obsessive relationship in which they only wanted to feel each other's fingers or mouth sucking her vagina hard while twisting each other's nipples and moaning together in pleasure.
