Wow. That was utterly intense. It was twisted in a way that a Slytherin could understand and appreciate, and a Gryffindor want, but not consciously realize - or is it that he does realize, jut cannot give voice to the desire? Harry really does respect Snape, but he really does not know enough yet to defeat Voldie - and he knows it... Snape still hopes and waits for the time Harry can succeed, but is frustrated, too. They care about each other, but are not ready to admit such - Harry needs the release, but can't admit to himself he wants Snape, and Snape is only too happy to share that release, both physical and of his angry frustration.
This begs for more! I'd love to see Harry learn what he needs to, and go on to defeat Voldie, and let Snape know that he really does have the memories of their time together... any chance for a continuation?
