I for one definitely enjoyed this, thank you! :) You wrote a kink I've never seen before, and given the time I've spent reading erotica, that's pretty impressive! :-)
Personally I don't care if it's tagged as such, but (for the sake of proper terminology :)) I have to say this IS non-con. At one point Sirius clearly wants to stop, and from that point on he's being raped, even though he's an annoying fuck who (quite literally :)) asked for it. In fact, if we wanted to be particular about it, it's non-con from the start, since Sirius gave his consent to someone else, not to the person he actually was with. Imagine a burglar, in the dark, sneaking in your bed instead of your partner - not quite consensual, is it? :)
