Part three of MILF1679. Following a second bout of cock-sucking from Abbie, Kelsey eats out her pussy before fucking her twice more, doggy and missionary style. Finally, step-brother cums deep in step-sister's unprotected pussy and then goes down on her. It is moment that seals a new and special bond between the pair. From that moment on they are inseparable. Many months hence, Kelsey is a changed man. He sits studying the Bible alongside Abbie. Occasionally he gives a proud and loving pat to her pregnant tummy.
