My new stepsister, who came into my life after our parents remarried, dotes on me so much that she treats me like a child. She hates being seen by others and is obsessed with tanning, so every time she returns from the salon, she orders me to apply aftercare oil on her body. At first, I reluctantly agreed, but as her oily, glistening skin aroused feelings I couldn't suppress, things began to change. She still sees me as just a little kid, so she never suspects anything when I touch her most intimate areas. That's exactly why I've started giving her erotic massages—to secretly get back at her for always bossing me around, and to satisfy my own growing desires.
