Chores With A Twist of Revenge Sex

My step-sister, Athena is always getting in trouble, this time she got grounded for a really long time. I found her in the laundry room doing our parent's bed sheet as part of her punishment chores. Athena is tired of my Step-Dad always telling her what to do and getting grounded by him. She is looking for some revenge against him, in her weird mind she thinks fucking me will get back at my Step-Dad. I am really horny so I just go along with the idea instead of her telling how dumb it is. I fuck my Step-Sister right there in the laundry room, if it was up to me I would un-ground her... that pussy is too good to be locked up in the house.
