That specific look. There was that one that was like a fire in John, and when they were talking about their evening plans during the party after the game, she had that look. Which just made him, what, what was it exactly? Certainly not think straight. Kitty just in general made him lose his mind, and not in a bad way.
So when the teasing and the touching and the kissing kept growing much heavier as the afternoon drifted into evening, and the evening drifted into the night with the fireworks starting... John was almost bursting at the seems when Kitty was well and ready to leave the show a little early. To be fair, Pyro would have done absolutely terrible things to her right then and there, but then people would have noticed and frankly he wasn't the most keen on sharing that experience with others. John was a little possessive of Kitty in that fashion after all.
So by the time they were pushing through the door of his house his motor was quite geared up. "I do belie-" But his words were caught quite short as her mouth captured his. Who needed to talk anyway? This was a much more pleasing thing to do with his mouth and tongue. Pressing his mouth eagerly against hers, his foot kicked his door closed behind him. Staggering slightly his weight shifted and bumped into the wall near them, which promptly worked for him.
A shift of John's weight while his hands dipped low, he braced and grabbed and hoisted her up pinning her to that wall they had found. Her words echoing in his ears while his mouth found a delicious spot along her neck. Mouth and teeth grazing the spots happily. "Oh. That energy not to murder has shifted in a whole different way." To show that more thoroughly he let his mouth press against hers eagerly before speaking again against her mouth. "Kitty, you are queen at distracting me."
