I was staying at my aunt's house in Tokyo to look for a job as a male esthetician. I hadn't seen my aunt since I was a child, but she was still beautiful even with her age, and she had a mature sexiness to her. I was mesmerized by her big ass wrapped in denim, which she didn't realize she had, and I couldn't take my eyes off her. I asked her to apply oil to her big ass as a massage practice, and I couldn't resist the shiny, slippery ass and ended up fucking her right away! It had been a while since she had had sex with her husband, and my aunt's sexual desire was released. I had sex with my horny aunt around the clock and came inside her!
