I was shocked to see my little sister, who is five years younger than me and whom I hadn't seen in three years, had turned into a slutty gal! But when I was surprised, it turned out she was only like that on the outside... Inside, she was still the same super shy and cute girl from before!! But then again, she had become a girl who loves sex! Because as soon as she saw my erect dick, she started getting excited and pounced on it! And in the end, she screamed "Cum inside me" while orgasming over and over!! I couldn't imagine this erotic growth from my formerly childish little sister. I was really shocked!
