Oh, holy cow, that was great! Great fun, great sex, utterly adorable premise. I think I love you, mystery writer! :)
I loved Harry's sputtering disbelief when he finds out where he's working, and laughed my head of at Hermione's reaction (especially to the 'Raunchy Runespoor'). Not to mention that the concept of a secret 'celebrities hair' market is just too brilliant to be true :).
And Harry going into his tryst all nerves, and then totally in love with the sex *and* then having the guts to reveal himself to Snape was brilliant. As were Snape's ordering him around and his taste in 'bedroom decorations'.
"I'd've enjoyed Potions a helluva lot more if you'd done that before" really cracked me up.
Great, entertaining and funny story - thanks for sharing!
