Ikatan ibu tiri

When Marcy finds out that her husband has been cheating on her with some slut at his office, she decides she's going to get revenge. Not just ANY revenge, of course. She wants this to be REALLY humiliating. To HURT. She decides she's going to need her step-son's help. Sure, she might have to tie him up a little... at first... just until he gets excited about his part to play in her filthy little plan. And of course, her husband will be watching the entire time. Step-Mommy is pretty sure her step-son has a bigger, better cock and she's going to find out, tonight... over... and over... Revenge never tasted so sweet.
