On her 18th birthday her parents had her move in with her next door neighbor. Every night since then, he’d fucked her ass, using less lube each night. He was training her to be the perfect anal slut, so she’d please her boyfriend when he came back from college. He barely had to use more than a few drops of oil with his spit now, though she felt like she was being ripped in two with each thrust, but she was glad he was so patient and helpful. Every mind shattering lance of pain up her aching ass reminded her that she was becoming a better slut. In only four years, her asshole would be a perfect hole for her boyfriend to fuck anytime he wanted.
