A while ago i stumbled to awesome guro on pixiv, but now author account is totally removed. There was a porno about man sitting to a bench to two girls and asking one to cut her head. (i believe on character was Uzaki)

Some works of that author can be fount on internet, but this one i have no luck finding. Can someone help please?

(other work of this author is appreciated, but i look for this specific one)
