So, I hate to be that guy who resurrects stories from a year ago, but I was struck by a wave of motivation. That being said, the thread appears to have been part of the 'Bermuda triangle' page. So, let's begin with a recap:
John's parents and Mel's parents are going on a cruise over winter break. Because of a recent string of robberies in the neighborhood, their parents want John to stay at Mel's house (so the potential kidnapper can get three at once? Not a good strategy) which is kind of awkward because they don't really know each other. When John arrives, Mel's slightly older sister Mallory is the only one home. John finds her television viewing choices unfavorable, so he decides to take a shower, after which, his clothes have vanished. Mallory has set a trap where John, searching for his clothes in only his underwear, opens the door to her room to find her in her bra and panties and she can accuse him of being a pervert. To 'punish' him, she gags him with her panties, strips him naked, and ties him to a chair in Mel's room. Mel comes home from show choir practice and takes a shower. She opens the door in just a towel, says "I guess Mallory knows I like you", locks the door and drops the towel. She removes his gag and, before replacing it with her own, passionately kisses John. She gets some bondage supplies from her closet while being awfully secretive about a large box on her shelf. She puts some clothes on and leaves John in the room. An hour passed and John manages to get free. Before trying to escape, curiosity gets the best of him, and he looks in the box...
Meanwhile, in a flash forward, the police arrive at the house and Mallory takes a deep breath and prepares to deal with it.
