Mom is upset and horny all the time

My dad has been searching for his spirituality for some time now. It seems like he wants to go on more retreats and spend less time with my mom. I don't like it and neither does she. She is upset and horny all the time. I want to help. She confides in me and we joke around. I give her a nice massage and start touching her huge breasts. She is getting turned on and tells me to be quiet. She takes over and sucks my cock and sits down on it until she comes hard. I fuck her from behind and push her down on her back and fuck her until I pull out and she jerks me all over her tummy and pussy. I love helping my mom when dad won't fuck her!
