The most striking thing about this, is how well the three of them fit together (er, no double entendre intended). The dynamics are more complex and subtle than what we often see in threesome/polyamory fics, I think. When Teddy and Harry first enter, it's clear that Teddy has grown into a confident man, an Auror, a person comfortable with holding his own with his older partners. Yet he so readily transitions to being pliable (again no double entendre intended...) and even submissive to them in bed. Not because he's younger or any such cliche thing as that, but purely because it's what he likes and it's how their relationship works. A truly good fit indeed. Love the smooth, dreamlike quality that increases with the intensity of the scene as well.
