My niece used to be very attached to me. It may be because my brother and his wife were busy and she often came to my house in the neighborhood. I felt her niece's growth just before entering school. I think she started seeing her as a woman from then on. Her niece saw an erotic video on my smartphone during spring break. She thought it was bad, but... she crossed the line with her niece who was interested in sex. To kill time, make her squirt with a hand man, make her cum with a toy, or do it without rubber. There is no romantic feeling to each other and they continue physical relationship out of curiosity.
