He promised to keep her in line. He kept her as his instead. His best friend's twenty-year-old daughter should have been absolutely off-limits for Max Williams, but Kelsey Burke's flirting and teasing have finally pushed him too far. She's going to get what she's been asking for, and it's not going to be anything like her naïve fantasies. It will be on his terms, not hers. It will be rough and shameful and it's going to hurt. She needs to learn what happens to naughty girls who trifle with a man twice their age. But it's going to take more than one lesson... Publisher's Note: Kelsey's Keeper includes spankings, rough sexual scenes, intense and humiliating punishments, and strong D/s themes. If such material offends you, please don't buy this book.
