I have a childhood friend from the same class. But recently, we haven't been talking at all, and while our parents are going on a trip, we're going to be staying at my house together... It turns out that she looks innocent, but she's actually an outrageous carnivorous nymphomaniac. She came into the bed saying she was too scared to sleep alone, and then she showed off her masturbation at our school, and even when I came, she demanded more and attacked me by riding on top. I was pulled out for 5 days straight.
