My niece looks simple and serious, but she's actually a slut who eats up all the boys in her class! Every time she comes to my house, she seduces me with her erotic moves. My niece's school is in the countryside, so there aren't many boys, and she seems to have already eaten up all the boys, so she goes after my dick whenever she gets the chance. I managed to hold her off, but when I finally got tired and fell asleep, she straddled me and inserted herself in me. What's more, my niece wasn't satisfied with just one cumshot, and she asked me to cum inside her so many times that her pussy overflowed...
