Step-Sister Caught Trying Libido Enhancer

It looks like my stepsister wanted to have a wild night with her friends at a party and planned to use a sexual stimulant to enhance her experience. She decided to experiment with it beforehand and ended up being overwhelmed by its effects. I caught her scurrying into her room after taking it, so I followed to see what she was up to.
Melody undressed and began grinding on her pillow, letting out uninhibited moans. I surprised her by walking in, but she appeared rather pleased to see me. She practically begged me to have sex with her, expressing a desperate need to have me inside her immediately.
Despite my initial reluctance, her persistent advances eventually won me over. Things heated up quickly due to her undeniable allure, yet the encounter left me abruptly dismissed and discarded once it was over.
