Stop her

You catch up to her just as she reach the door, gently grabbing her arm and turning her around while using your other hand to close the door.

Again you break the kiss after just a few seconds, knowing she'd get uncomfortable if you held her longer. You also make sure to give her enough space, so that she could easily escape from you if she wanted to.

She doesn't escape. Instead she just watches you intensively, staring into your eyes as if trying to figure out what you'll do next.

Problem is, you barely know that yourself...
