This is so great. My icon cannot even express it. Of course the sex is hot, but that's just icing. I love the dynamic with Severus and Regulus, how Regulus is gentle but also has fire, the way he calms Severus and helps him feel he has a place. Seeing his thought process on why he wants to join Voldemort was very cool. And Severus being all bitchy and "I can take care of myself" is spot on.
"You mistake compassion for love, Severus, and there is no one more deserving of it than you."
"And I was referring to your arm, not your arse."
"Again, I was referring to your arm, not your arse."
LOL. OMG. This made me laugh so much. I love Severus's sense of humour.
