Harry Potter and the Charm of Venus - Twins
By Marjorie
From Chapter 3. Harry gets lucky with the Patil sisters.

Welcome to the realm of the Unseelie Court. Feel free to wander and browse, but know that the content you will find here is not for the faint of heart. The visions portrayed are often darkly erotic, even disturbing, and should be traversed only by those with the appropriate character and mental age.
You have been warned.
