  Summary

  Shirou has been planning a very special birthday celebration for his beloved sister, the cute and adorable Illya. However, it doesn't take long for a few of the guests to turn the party into nothing but the most FUCKING PERVERTED day ever, and Shirou has no other choice but to take matters upon his own hand! 

  Co-written with Master of Chaldea.
