Oh. My. God. This is just so perfectly dirtyhotwrong and I love it. Absolutely love it. The way you've written Regulus is amazing, and I really like how you've defined his relationship with Sirius - that they'll do this but not touch each other is so wonderfully in character for both of them (and so very kinky, I like it).
Thank you so much for filling my prompt with this slice of perfection.
