Step-Mommy has noticed you've been avoiding her. She's worried she has done something but she can't think of what could have upset you this much! You were always so close and now... You've barely talked in weeks. There's nothing step-mommy wants more than to make things better between us. Step-Mommy needs you.
She tries to lighten the mood and coax you to open up to her. There's a moment where you wonder if she is flirting with you. You decide you'll tell her and screw the consequences. You never know...
You tell her you've been finding it hard being around her with how she dresses. Right now she is in a skimpy black silk robe that doesn't close over her massive tits, and you can see the suspenders and stockings. It's almost like she's trying to drive you mad with her body.
She isn't angry or disgusted like you thought, she actually understands. All her friends have had the same thing with their sons. It's completely normal to look at step-mommy like that. I would be upset if you weren't.
Things take a turn and Step-Mommy goes into full seductress mode to get what she wants. Her step-son, fucking her asshole like the dirty step-mommy she is.
perfect mommy, and a very fuckin hot lady
