I'm confused.

I'd say I'm so confused I hit myself, but you'd take this the wrong way.

Clearly the perpetrator of this case, the villain behind it all is.... LEONARDO DA VINCI! After all, there is no reason for the Rayshift Loop Devices to already be prepared in quantities to support all the female servants getting the effect at the same time, nor for how to deal with it to have already been known the moment the phenomena began.

No joke. If things like this exists, I would've fucked my own ass silly. Also suck my own dick. Cause why not.

To feel the feeling of penetrating one's own pussy and being penetrated by one's own penis at the same time... Intriguing, yet highly disturbing.

Are you sure Merlin has nothing to do with this?

>all the females in Chaldea grow dicks, including some of the Arturias

Merlin's got to at least be involved in this. And if he isn't he still deserves the punishment, damn dick wizards.

Base +6

Leave it to Da Vinci for your wacky Chaldea sex hi-jinks.
