Tao is a 20-year-old second-year economics student. Wearing panties with an extra-thick vibrator locked deep inside her pussy, she became absorbed in a game of "Daruma-san fell down." This isn't your typical kids' game—it's a far more erotic version, better described as an "Ikase game." Rather than aiming to clear the game, the real objective is to fill her wet, squelching slit with thick vibrators and then unleash massive creampie after creampie. Her body grows increasingly sensitive from the vibrator's stimulation, transforming into a more and more erotic state as the game progresses. The so-called "prize money" she earns along the way ultimately becomes irrelevant—the true essence lies in surrendering completely to the overwhelming pleasure.
