My Asian step-sister was doing her daily yoga routine in some rather sexy and transparent tights, so I had to take a peak, I was enjoying the view when the opportunity came knocking, a bottle of oil next to me, I started splashing her ass with it and I could see her big ass and juicy pussy through the tights now, she immediately started ripping them off and exposed her sexy body, took my big hard cock in her mouth, and told me to fuck her before the parents came back, so I did fuck the shit out of her right outside the house, next to the pool where the neighbors might see us! She dumped my big fat load in her mouth, it was so much she almost choked on it.
