My sister’s ass is irresistible…! As she was hanging laundry, I approached her from behind and secretly ejaculated on her! Thinking I wouldn’t get caught, she found out immediately, so I quickly thrust into her to cover it up! Her pussy felt so good that I creampied her multiple times, making her forget about the ejaculation. From that day on, I couldn’t resist the urge to ejaculate on her ass whenever I saw it.
