My neighbor is a beautiful, slender older sister who has a beautiful ass. Because I was a neighbor, I helped her from time to time. One day I lost my key, the owner of the apartment was traveling, so I didn't have a spare key. I didn't know what to do when Kashii-san caught me and invited me to stay in her room for a few days. Looking at the pile of seductive underwear, plus the fact that she kept bringing her beautiful ass towards me, I couldn't keep my mind anymore. I rushed over to massage, inhale the scent from her body and then put my erect cock inside her! She didn't seem to reject me either, she always said this was the last time, but for the past three days, I don't know how many times I've cummed inside her...
