As you settle in for your pleasure sesh, you slip into your leather boots and push against your stair step to begin your journey.Your fingers slide down onto the taut material of your pants and underwear, revealing your long, slender figure beneath.Your breasts hang heavy and firm, a contrast to the delicate curves of your body.As you climb up the steps, your mind races with anticipation, knowing what was waiting for you just around the corner.You reached the final step, and turned to face your partner in the shadows, your heart pounding with desire.Anal sex? Now thats some good fucking, he said, his voice rough and thick, sending shivers down your spine.He stepped forward and began caressing your ass, running his hands over the smooth skin and pulling down your panties, revealing your bare ass in front of him.You watched in anticipation as he climbed up behind you and pressed himself deep within you, filling you completely.Your moans filled the room, growing louder and more urgent as he fucked you harder, his cock sliding deeper inside you with every thrust.And then suddenly, disaster struck the tension built up until it released in a forceful blast, spraying the walls of the staircase with cum, and leaving your stepmom caught in the crossfire, drenched in bodily fluids.She stared in shock as you continued to spurt, losing yourself in the sensation of her body tightly gripping around your cock as you blasted one load after the next into the air before finally collapsing in exhaustion atop the stair, your partner standing there watching with a mix of satisfaction and horror, knowing exactly what had happened.
