And that movement Axel just did? That felt nice. He might mess thing up by acting too eager or too clumsy so rather than take some initiative, he moves again, hoping to prompt another grind to meet, each time feeling less ashamed about liking the contact of their hips while keeping himself busy and distracted with the kiss.
He's going to push his luck a little, letting his hands wander down to play with the big zipper of Axel's coat. He'll pull it down and slip a hand in just to test and see what happens. ]
