She wasn't ready for the kiss and she instinctively pulled back a little. then she kissed him back.  she didnt want to lose him not now not ever.  She wrapped her arms around his neck her fingers playing in his hair.  she pressed herself closer to him as she kissed him and pulled back blushing and looking away.

"oh liz dont worry, it will be okay" he says "you have nothing to worry about" he kisses her lips.  "and thank you" he smiled at her.
