themed recs: first times

[sori1773]

I love first times! Seriously, first times are pretty much the staple of my fanfic reading. :D Maybe a few of you share my love?

So, what are your favorite first times? Het or slash! Any and all pairings! Let's share the love!

(And a quick friendly reminder: Please provide the pairing with your rec. And, as always, we prefer no self-recs here at spnroundtable.)
