I love first time fics. This one is so sweet. Rose knows how nervous the Doctor would be and how much he wants everything to be perfect for her. She is certainly the brave one and can imagine her taking the first step. It is a role reversal for them, but one that is totally in character.

Poor Doctor, always worried he'll do something to mess up with Rose and then she'll be dissatisfied and leave him. You put that so well in this passage.
The Doctor lifted his jumper over his head, gathering it up in his hands, with each layer of clothing he subtracted from himself, the more anxious he became. What if he disappointed Rose, what if he wasn't good enough for her, what if she realized this moment that he was too old for her? So many 'what if's' suddenly bombarded what confidence he had. With his body completely bare, his eyes fell to the floor. He looked up, dreading to see Rose's face.

Rose is wise beyond her years and the Doctor trusts her with his body and soul. His trust is not misplaced. Their lovemaking was so tender and slow. Beautiful.

Thank you for posting this!
