Ichika Matsumoto celebrates her 3rd anniversary! Starting with zero production costs! The plan is to make an AV using only the money earned from horse racing, and the funds earned from selling personal items and guerrilla events at stores. The goal is to go and meet her beloved horse King, who was active as a racehorse. (Icchan is actually the horse's owner!) If she fails the challenge, she has to give up her horse as a penalty... Using the help event (1000 pistons = 1 yen), she rides him hard, swinging her hips! She uses her pussy to cum inside her horse and earns production costs!
