I used to fantasize having sex with my niece, who is my sister's daughter. Though she is a minor of age 13, I have a sexual attraction towards her. I have even masturbated by thinking of us having sex. I imagine things like she is sleeping on my chest and me massaging her clitoris to make her to sleep and slowly moving forward to lick her clitoris, making her to suck my penis, sucking her little breasts and finally drilling her holes with my penis
