"What is the Licking Dog Championship!?"

I, Reiko Nikaido, have all the family, educational background, good looks, and money one would want, but no man is good enough for a long time. But because of a promise to my father, if I don't bring a man who can match my taste by 30, I will have to make a match. And tomorrow happens to be my birthday. I was disappointed and drunk, and I arrived at a suspicious shop in the downtown area.

What!? Everyone is doing cunnilingus in front of the crowd!? For some reason, I also end up participating and getting licked by a man on the stage.
