Looking for an old [amazing] erotica

A while ago I read a great story, but I forgot the name/author and can’t seem to find it anymore.

I believe it was called Coitus, but that doesn’t narrow it down much.
The plot: it was about a sex-crazed boy who discovers a new vr game where women go to have virtual sex. He takes advantage of this and replaces the fake body parts with his own.
There is 5 chapters. If anyone had the link, or knows how I can find this story please tell me.
[P-s: i found the story in Archive of our own]
