Alas, the expertise of the kiss is sadly lost upon someone like Stiles, who has never kissed anyone in his seventeen years of life. It also doesn’t help that he’s so shocked that he just stands there going cross-eyed from trying to stare at Heiji the whole time, eyes round as saucers and mouth utterly slack. This could be the best or worst kiss ever, and it would have had the same effect on him. He doesn’t discourage the kiss, but he doesn’t exactly participate either—his brain has short-circuited and is simply spawning seemingly random mental images at him: breasts, yield sign, a little fox, coach demonstrating the correct way to apply a condom, etc.
