Wow, that's really lovely, all the little details, Sirius' decorating and Remus finally giving in now he's got no other choice. I like the tone, so hopeless at first and yet he's doing more than going through the motions and there is a future if he lets Sirius help him by the end.

"But now the bliss of this warmth turns into a womb, and here his body needs mine."

Love this line, such a gorgeous description.
