You have moved back home to your step-MOM after recently becoming single. She is divorced from your step-dad and lives alone. You supported her through their divorced and developed a really strong bond with your step-mom; you crossed a line that should never be crossed between a step-mother and step-son.
She is happy to have you home but soon realises what your intentions are, she tells you its wrong and should never have happened and she is actually seeing someone new. One thing leads to another and she can't resist you, she sucks your cock until you cum on her face, the next day she is very regretful. She tells you her new man is coming over.
You watch your step-mom and new man having sex, you can tell she's not really into in and definitely not enjoying it as much as when you used to have sex with her. The next morning you catch her at the front door saying bye to the new guy; she admits that they had sex and that it is obviously different to you and just takes some getting used to. Its not long before you are between her legs eating her pussy and making her cum.
Later that week the new guy is round cooking dinner in the kitchen, your step-mom thinks you can both have a lot of fun with this. You both sneak into the living room and she sucks you off, rides your cock and you cum all over her tits all while her new guy is in the kitchen! You are such a bad influence on step-mommy..
Later that week your step-mom confesses that she was trying very badly at resisting you but realises you are all step-mommy needs. You are perfect for each other and can finally be together! She dresses up in lingerie that her new man got for her, for you. You have passionate foreplay and sex before giving step-mommy a huge creampie, she answers the phone to her new man and tells him its over.
