Oppai no Ouja 48: Nanimo Kangaezu Me no Mae no Oppai Zenbu Shabure!

Naoya likes breasts. In fact, he's so obsessed with them that he can recognize any breast from just a picture. But while that's an impressive ability, who would expect some mysterious patrons to set up a game where Naoya has to locate five championship breasts from among all the girls in the city? Oh, and to have a lot of sex too.

That's exactly what happens when a girl named Nir shows up and gives Naoya the rules and a stack of free sex vouchers. That certainly doesn't suck! Or, actually, with his free vouchers, that's on the table too… With everyone from his teachers to the girl giving out free samples on the corner as possible "game pieces," Naoya's going to have a long, hard and very probing time ahead of him as he seeks to prove that he's the King of Breasts!
