Summary
Sirius Black really loves his boyfriend’s cock: thick, flushed, and crowned with a knot that swells when Remus gets excited. When his curious little brother Regulus finds out just what Remus is packing, he decides it’s only fair he gets a turn. Sirius has always been a generous big brother, of course he’s more than willing to share.
