I ended up staying at my aunt's house in Tokyo for a while. My aunt, whom I hadn't seen since I was a child, was fair-skinned and beautiful, and above all, she exuded adult sexiness. And then I became captivated by her denim-clad ass, which she didn't even realize was sexy, and couldn't take my eyes off of it. I couldn't stand it anymore and immediately had sex with my aunt while she was cleaning in front of me! Then, my aunt's immediately cumming pussy squeezed my dick tightly and I re-experienced pleasure! Nuoh! What is this feeling! I, who had tasted my first vacuum-like convulsing vagina, couldn't stop my erection even after ejaculating and had my sperm squeezed out many times. This is a record of the several days when I fell into my aunt's convulsing vagina orgasm.
