She's being so good about it, even though it isn't easy for her. But she wanted to make him happy, so she endured his cock up her sensitive ass until he finally came on her face. What a wonderful woman!
there's something magical about the moment the girl relaxes, and the head of the cock passes the asshole's ring, and the shaft gets fully inserted inside. the girl usually feels very content and full with the penis inside. quite a magical experience for both partners.
