How is this prelude to a kiss (or a moustache-sucking) as hot as the hottest smut?
And imagine if there actually was a fic about moustache-sucking. Think of the intricate details and intimacy it must involve! Sex and sensuality with hair can be so much more awkward that any other aspect, so it would be an interesting aspect to explore.
I'm glad that you enjoyed the canon spin-off. I was actually researching canon-Horace when I found those lines and decided I just had to write a fic off of it.
