Kim and Bonnie, stuck together butt to butt, thanks to Dementor, have arrived at the Possible's house. After Kim explained to her parents what had happened at school, she headed to her room,dragging Bonnie along behind herself. Bonnie is fuming,since she has no respect for Kim. She is blaming Kim for what happened. Kim replies that now matter whose fault it was, that there is nothing they can do about it right now. After getting their supper, Kim and Bonnie go back upstairs, to get ready to take a shower. The rivals go to the bedroom to take off their clothes, before heading to the shower. When Kim pulls her skirt down, Bonnie yells, "What are you doing?" Puzzled, Kim finished removing her skirt, and she knows why Bonnie had reacted. It turned out that Bonnie's skirt was stuck to the back of her own skirt. Kim, next took off her top, which thankfully wasn't stuck to Bonnie's. Next, Bonnie pulled her panties down over her hips, and found out that Kim's panties were stuck to the back of her own panties. Now that both of their butts were naked, Kim hoped that they might be able to get away from this uncomfortable situation. However, as much as she tried to pull her butt away from Bonnie's, she found that she couldn't. Bonnie suggested that maybe they would have more luck if they both tried pulling at the same time. Kim, realizing the sense in Bonnie's suggestion, agreed, so for the next ten minutes, they both tried to walk away from their rival. They had no more luck than Kim had had by herself. Reluctantly, Kim said that they would have to take their showers at the same time. Bonnie, knowing that she is somehow stuck to Kim, grumbles, but agrees. Kim pulled a large towel around both of their torsos and they to the bathroom to get their showers. After finishing their combined showers, Kim and Bonnie dried themselves off, and headed back to the bedroom, to get ready for bed. Kim loaned Bonnie a pyjama top,and she put one of her own on afterward. Kim grabbed a pair of pyjama pants, but had no luck pulling them up past her butt. Bonnie, stuck as close to her as she is, had felt every little movement that Kim had made. Reluctantly, Kim told Bonnie that it looked like they would have to sleep in the nude below their waists. Bonnie was grumbling, but knew that they didn't have a choice. Working together, albeit reluctantly, Kim and Bonnie got in bed, and pulled up the covers. Bonnie, even though she won't admit it to Kim, is secretly enjoying the warmth and closeness that their bare butts are feeling, stuck like they are. Aided by the warmth that their butts are generating between them, Kim and Bonnie fall asleep within a couple of minutes.
The next morning, Kim and Bonnie awake, having had a good night's sleep. Bonnie, as her brain fog slowly clears, realizes that something feels different, as if something happened overnight. Kim, for her part, has just noticed that things feel different this morning. After about ten minutes, Bonnie realizes what feels different. She can feel Kim's tailbone pressing against her own tailbone, but she can't feel any pressure between their bare butts. Getting out of bed, Bonnie dragged Kim over to the mirror on her door, and was shocked to realize that their butts have apparently disappeared, leaving herself and Kim, sharing one spine, or at least only one tailbone between them. Experimentally, Bonnie puts her hand on her back,but finds that she can't get her fingers in between her back and Kim's. What's next for our conjoined rivals?
