I love this style.

I would love to start by gently touching the middle with my tongue, very slowly, just push against it lightly and to feel the softness of the hair on the tip of my tongue.

And then, gently push my index finger into the middle, this time to feel the softness on my finger, and also...to very slowly, little by little, make a small "hole" in the middle.

The hole is for the final act...to insert my cock into the middle and fuck her bun. If the bun opens up before I come, it is also okay and fun. If not, then really all the come is deposited nicely into the bun.

Now for my contribution of some pics of a slightly different style, but similar concept, together with a question: at which point does a bun become an updo?
