I *adored* Ron here, observant and resentful of being mollycoddled (literally so!), and wanting something for his own, and *so* fascinated by Harry's godfather and the prospect of sex because it will make him an 'adult' where nothing else will. Wow. Ron is probably my softest spot in all of HP fandom, and you nailed him perfectly!
And Sirius... wow, yes, somehow he has *both*, the brooding, miserable side of OotP and nevertheless a seductive, thrilling side, and you got that accross so well with. And yeah, he's drunk as heck, but I could almost see him doing the same thing sober, because yeah - that's Sirius :).
I loved the barest touch of dubcon in this, with Ron *knowing* he's out of his depth and not ready for actual penetration, and talks himself into it anyway to prove himself to Sirius (and to himself too...). And so, so hot too - the stroking and the fingers and the delicious, sensual writing, almost a dream... yum.
Mystery writer, thank you so, so much for this great gift! That was *so* worth waiting for!
*pounces and snuggles*
And I'm so happy you had fun writing it, because I sure had fun reading :).
