Early Bath

I have recently fucked my adult step daughter, she loves the fact that I'm cheating on her mum. Her sluttiness turns me on. She won't let me make love to her, I can just fuck her when she wants , and only when she wants it, most is when her mum is in the bath. Her mum has put on weight since we first met and sex is infrequent, but she does make fun of her mum, sayings it's her fault that she can't satisfy me and saying we can hear her getting out of the bath and we fuck really hard and fast in the living room, as her mum gets out of the bath and pulls the plug, she rides me and is filthy, telling me to fuck her slut pussy, fuck your whore daddy, leave your cream in me, she has a contraceptive implant so I am in heaven, and then the dirty minx says make sure her I get her mum to suck my cock and tastes her juices. It's so fucking hot, I'd love to just take my time with her, but all I get is filthy quickies, no point in complaining.
