Matrigna infedele manipolata dal figliastro

Thinking that I am all alone in the house since my husband is out of town and my stepson is with friends, I've invited a friend of my own over. I love my husband but he is quite a bit older and unable to fully satisfy all of my slutty whorish needs so I have a few guys that I like to have cum over when he is gone. Unbeknownst to me my stepson has returned home early. Hearing strange noises from his step-father and stepmother's bedroom he knocks on the door. I'm startled. I take a moment to compose myself thinking that it is probably just the housekeeper who I know from past experience will keep quiet. Unfortunately it is my stepson, who hates me. I try to lie but he isn't stupid, he knows exactly what is going on. I beg him not to tell his step-father. He won't, but now it seems he wants his turn at stepmom. Not wanting sloppy seconds he will not fuck me (this time). He wants to watch me fuck myself and have me give him jerk off instruction/encouragement. Ok, I will do whatever he want
