*flails* I am a HUGE sucker for this pairing. Even more so for sweet, clueless Regulus who is still willing to stick his arse out for Remus. And Remus, oh god, I love him just like this. Rough, dominating, so very wolfish. And giving Regulus a blow job in the middle of Forbidden Forest! I have the biggest kink for Remus giving blow jobs, and it's only made better with Regulus is the one moaning and groaning.
Gah! So fucking hot!

Aside from the sexiness of the story, I loved the details of Sirius' and Regulus' relationship, so flawed and Sirius such an arse.

My God, this is how I always envision this pairing and you did it so freaking well!
