I had a oral sex with my brother who is 7 year old. My brother sucked my penis several times and I released many times my sperm in his mouth. He is not interested in this but I give some chocolates and do oral sex with him and I kiss on his lip and touch his teeth. I am feeling very bad for him but I can't control myself when I see him. Does this can cause any disease to him? And please suggest me how to get rid of this.
