Stroked off by your stepmother to keep her secret - Taboo Handjobs

My stepmom is pretty hot. I have fantasized her a lot while growing up, and admittedly have a little crush on her. One day I came home early from classes, and I heard some noise coming from my parents bedroom. I knew my stepmom and stepdad were at work, so I cracked open the door a little bit to see if we were being robbed or what. What I saw in my parents room was so shocking that I couldn't believe my eyes. I saw my hot stepmom in bed with some strange guy! I know they couldn't see me, so I watched for a while, getting angrier yet more turned on as this big dude pounded my stepmommies pussy while she moaned like a slut in heat.
