"Alright, I know what I'm going to do," says Logan, standing up. You gulp nervously, hoping the punishment isn't too bad. But there's a twinkle in his eye that makes you fear the worst. With a quick glance over, you see Trevor has a smug look on his face. Logan steps forward, in between you and Trevor, and closes his eyes. You can hear him chant under his breathe, but can't make out what he's saying. It doesn't matter. It's not as if there's anything you can do. All the lights in the room dim, the window clouds over. It's all dark. The faint voice of Logan can be heard, completing the spell. You gulp. This is it.
But it's not. You decide you need to get out of this situation, and there's only one way to do it. You rush forward, barreling into Logan. Both of you go down, just as he finishes his spell. There's a crack of lightning and the sound of Trevor shouting out "No!" can be heard, and as the lights begin to fade back, you black out.
You're only out for a few minutes, at least it seems like that when you come back to your senses. Lips on your own lips, someone trying to shock you awake. With a kiss. You fail to see the logic in that, but something's got you awake, and you blink several hundred times that minute to work things out. Things feel different. You feel... bigger. Bigger then you felt before, in your own body and in Trevor's body! You start to get an idea of what happened and clearing your eyes confirms it. The lips belonged to Trevor, who's looking down at you with a loving face. You think it's odd compared to his attitude to you earlier, but looking down at your body confirms you are now Logan. Rushing him during the spell must have affected it somehow and your collision with Logan knocked your consciouses into each other's bodies.
Trevor offers a hand, you accept it and he pulls you up. Whilst he isn't looking, you cast a glance into the mirror. You've got Logan's cheeky chappy grin on you know, and those adorable brown eyes. You look picture perfect, even your strawberry blond hair (you'd never really been attracted to neither gingers nor blond's before) isn't enough to dampen your mood, and seems to increase your hotness. Your pecs are visible through your shirt, much more defined then Trevor's, and your penis, as you found earlier, is longer then Trevor's and yours, both flacid and erect. You rub your chest, but it's really just a chance to feel those muscles underneath your shirt without alerting Trevor to what's happened.
Meanwhile, Trevor's been trying to work wake up Logan in your body, and it seems like he's just succeeded as Logan blinks stupidly rubbing his head. "Wha - what happened?" he asks, groggily. Putting on a snarl, you stride past Trevor, backhanding the teen back into unconsciousness for. "What was that for?" asks Trevor, slightly startled. "Hitting me," you respond, calmly. Trevor seems to think that's an acceptable answer as he closes in for a kiss and you deliver, savoring the moment. This is the life.
