Undercover investigation at the cosplay mecca! We approach a popular cosplayer who's a favorite among camera enthusiasts and invite her to a paid photoshoot! We bring her to the Magic Mirror van parked nearby for a challenge! Cosplay showdown! First to orgasm with the cock ring wins a 50,000 yen prize, but the loser gets creampied on the spot! Even though she says "I can't do it, it's too embarrassing," the prospect of getting creampied if she loses makes her shake her hips intensely and ride the cock ring with excitement! Her first taste of pleasure has her completely aroused, and she squirms and squirts with abandon! Who will emerge victorious in this cosplay battle?
