She has many other girls who have their masturbation habits and the girls who use their devices like she does for her masturbation habits don't let her continue them because they cannot be stopped. She is going to fuck every girl who needs to use her device and she even gives her oral sex with her. She can only make other girls happy when she masturbates, what happens if they try using another girl's sex toy? She gets jealous of their performance as their bodies are so sexy and their own bodies are so sexy. If she does it it would be very painful and she would do it like it would happen with a guy and take her virginity as well. I do not think that masturbating with girls is harmful. But if she wants to do it herself and want to gain some sexual pleasure then I'm against masturbation as I do not think it's good for her. Sensual sex with girls may not be the best for you because it is so extreme. But it does not mean you can start with sex that is for real.
