***PLOT:*** Your working out in the basement and your step-mom comes down to check on you since she can hear you working out from upstairs. She hasnt seen you in awhile due to being busy with work and you always being out and notices just how big and strong youve been getting with working out. She's really impressed! She asks if you can lift those heavy weights next to you and you show off just how much you can as she tells you how strong you are. She starts comparing you to your step-father saying how out of shape he is and that he should go to the gym with you. She cant help but look at you..with all your big muscles...she asks if she can come touch your big strong arms and then your chest...shes getting really turned on now seeing her handsome muscular step-son. She takes her tits out and shes desperate to get fucked. She starts riding you and fucking you saying how big your cock is and how muscular you are compared to your step-father. She needed this, she hasnt been fucked like this in so long and is tired of putting up with your lazy step-dad pretending shes enjoying it in bed with him. You both hear your step-dad come home and open the garage so the two of you quickly clean up and step-mommy tells you this will be our little secret.
