I left a reply on the main community that you might want to see. In the meantime:
EEEEEEEEEEEEEEEEEEEEEEE!!!! WOW, did you manage to hit my kinks with this! Grimmauld Place, shower sex, mutual masturbation, the love of cock, even the trio being trio-y....*blush blush blush*
I loved Remus' line about his love life being none of Sirius' business and the details of Severus' dream/memory. I also really liked both their characterizations here. Severus is Slytherin in positive ways, which works so well with who we know him to be, and Remus is calm, easy-going, eager...they're both so yum!
*HUGS HARD* Thank you so much for this, and for being a part of my fandom life. I'm so happy just to see fic from you again! *more hugging!!*
