No teenager was built for marathon activities beyond a certain point, and knowing that, he would rather move slowly for now. Even if all he got to do was kiss Mary this time around, hold her this much, he could tell himself that he was perfectly fine with that. Even as he inched one foot forward, and leaned just that much more towards her with the rest of his body, the hand he had on her shoulder pulling her gently right back towards him.
Oddly enough, her fingers sliding into his hair reminded him (after the fact that he really did enjoy that), that he did need to get a hair cut one of these days.
The thought flickered and was lost again, as he opened his mouth just enough to be able to slide his tongue along the seam of her lips. Asking for entrance, but not demanding.
