Harry isn't proud of the scars, nor is he ashamed of them. They're a part of what he is and who he is. There's something erotic about having Neil trace them each with his fingers, though it might just be that he's been deprived of delicate touches to his body for so long and any touch would go straight to his cock.

Rough hands trace gently the boys frame, feeling the soft skin, the slight reactions he's causing, and it's delightful.

Eventually, his hands make it to that waistband again and they tug at it.
