Step-sister's card game leads to intimate exchange

After a heated card game, my step-sister couldn't resist the urge to seduce me. She dropped to her knees and took my cock in her mouth, sucking me deep. I loved how eager she was to please me. The taste of her lips on my skin drove me wild. Soon, she was bent over, her ass exposed, ready for me to take her from behind. I did just that, pounding her hard and deep. Her moans filled the room as I fucked her. Then, she mounted me, riding me cowgirl style, her tight pussy squeezing me as she rode me. The sight of her beautiful body moving on top of me was too much for me to handle. I came, covering her ass in my warm, sticky cum. It was the best sex I've ever had with my step-sister.
