Matsumoto Ichika, celebrating the 3rd anniversary! Starting with a production cost of 0 yen! Selling personal items, store assault guerrilla events to earn military funds, and using only the money earned from horse racing to make an AV. The goal is to visit her beloved horse King, who was active as a racehorse. (Ichika, actually a horse owner!) With a penalty game of giving up her beloved horse in case of challenge failure... Using help events (1000 pistons = 1 yen), aggressively shaking hips and riding position! For her beloved horse, she uses her own vagina to earn production costs through internal ejaculation!
