Family party at your aunts, everyone is having dinner, but my step-son is staying in another room to play PC games, Call of Duty or something if I recall properly. I arrive a bit tipsy, mistaken the room for the restroom, so I lay down on the bed instead. You, my step-son, are going behind me and slowly start groping me with your dick. I tell you to turn around and instead you pull your pants down and move your cock between my thighs and pressed it on my pussy and start rubbing harder. Then you touch me and move your hands on my pussy. As your step-mom stops struggling and starts to enjoy herself, you get up and lock the door. As you come back to me, I already know you will make me your slave. So, I give you a footjob. Then I take out my leggings and you fuck me doggy, on the side and missionary. At the end I submit hard to you. I become your whore, your pet, your slave. You creampie me and impregnate me
