Fantastic entry! The leisurely unfolding of events and corresponding emotions was well-written, allowing the reader to enjoy the hurt/comfort. Harry making Spinner's End into a home has to be one of the all-time best ways of getting Severus to really see the Boy Who Lived.
This line is so expressive of the beauty of the writing: Quite simply a naked and writhing Harry Potter, spread out before him like a feast on a bed of feverfew, was by far the most erotic, the most delectable thing Severus had ever seen and he spread the boy's legs wide and leaned forward to partake of the proffered feast.
The image is classical in allusion and erotic in atmosphere! Along those same lines, your references to The Little Prince both fit the emotional context of the scenes in addition to driving the narrative.
