I must confess that the moment I read your summary, coupled with the unmistakable connotations of your choice of title, I wanted to read this piece straight away.
I love the very idea of Severus as a stern professor in a phone sex line. He does have the voice and the right attitude for it, doesn't he?. One of the things that most struck me with this story, though, was how certain Harry was that it was Severus. He never really bought Sev's denials, did he? and that shows both how deeply they've come to know one another and how ready Harry is to move their relationship forwards, even in an unconscious way. The idea that Severus has been plotting made me smile so hard, and I adored the fact that he never really confesses outright. That is just so... him! ;D
Thank you for taking the time to participate in this fest and gift all of us with this wonderfully entertaining and original story. It's both lighthearted and beautifully romantic. A perfect pick-me-up read.
