Fertile Sister-in-Law. Mature Futas, #50

Mel was the youngest of four siblings and younger by quite a few years at that. It allowed her to have a spoiled childhood, where she got all that she wanted. She admitted it had made her a bit of a brat, though she liked to think she had put that part of her behind. Then she met her sister's new wife, and she found herself wanting something she shouldn't. Giovanna was a gorgeous woman, quite a bit older than Mel but not less desirable for it.
Quite the opposite. That she was a futa only seemed to enhance her allure. Mel would never do anything untoward. She wouldn't risk her sister's marriage. And yet, her sister ended up being the one to mess it all up, giving Mel a chance to fix it, though what that involved.
