Do you know the game Twister? It's a game where you have to hold in your pee while being subjected to a vicious electric massager in an awkward position (just kidding). The girl taking on this challenge is Mirei, a beautiful classical sailor girl from the tennis club at a prestigious girls' school. First, you drink some tea (with a diuretic in it). Then you spin the roulette, and your right hand turns yellow -- but wait, some kind of juice is already leaking out of your vagina! "It's okay..." she says, so the electric massager remains on even as she slowly weakens. She grits her teeth and endures the pleasure, but in the end she fails the challenge. Now it's time for the staff to cum inside her! He licks her beautiful white skin and thrusts the vibrator into her, pistoning her hard at high speed, causing her to squirt a huge amount of juice in joy!
