She drinks a potion and suddenly it's a threesome!

"Ah, now I know what we could do," Rikku says and starts looking in her satchel. "Here it is!"
You look at her with a puzzled expression as she pull out a small potion contained in a vial. "What's that?"
"Dont worry, I promise that it'll spice things up a bit," Rikku says and grins. Without any further ado she downs it in one draught and flashes a broad smile at you.
"Now the fun is beginning..."
Rikku starts moaning and you notice that she is quite wet. Then she starts getting blurry all of sudden, as if you looking at her in a funhouse mirror. She twists in ways not physically possible and emits a light, blinding you for a moment. When you recover, you are amazed to see not one, but two identical Rikkus smiling lewdly at you.
