The Slave Game

Mackenzie expected a long lazy summer holiday at the cottage with her friends and their parents, people she'd grown up with and thought of as family. A chance to relax after a hectic first year at college. What she got was a deliciously sinful game of play-bondage and play-lesbianism with her more sophisticated female friends. It was all wicked and exciting, of course, but became far more of a thrill when their brother joined in.
Gradually, over the days and weeks, the game took hold of her, and so despite her shock, she offered no resistance when others joined in, and the game became decidedly more real. Now the punishments were darker, the submission deeper, and Mackenzie became a slave outright, a naked sex slave and servant at everyone's beck and call, caged and crawling, and punished for the slightest misstep. She was given to others, used in lewd sexual parties, and then - things became even more exciting!
