The noises she made fueled the fire in John which were already absolutely running hot as it was. The way her body moved to his touches and her reactions just drove John to want to tear the last shreds of fabric from her body. Touch, feel, and enjoy her entirely. Deep down, everything in John wanted to rush forward. All the way.
But! John most of all wanted to make sure that she was quite taken care of. In a number of ways. Pyro was selfish in so many ways, but he wasn't a selfish lover, that was for sure.
Kitty's plea did not fall on deaf ears. Not one bit. With quick and eager motion, John pulled aside the piece of fabric that was stopping him from achieving his goal. His mouth, or more appropriately his tongue pressed up against her core in a solid way. His tongue kept pressure as moaned slightly against her. If you were to tell him that he'd be on his knees in front of Kitty Pryde in a very compromising position when he had gotten here, he'd of laughed.
Though, honestly, he didn't want to be anywhere else other than here in this spot with her.
