Ringetsu 2

Naoto Rindo's mission to produce an heir before his family's deadline is going better than he expected. At first he didn't think he had a chance with any of the three cute Hizuki sisters, but after a few short days in their home, he's already given nakadashi creampies to shy Ayumi and nerdy Mizuna. Not only that, as the girls' interest in fucking has grown, he's managed to talk them into public porno online in the library and in the stairwell at school! Even big-titted Shino, who tried to drive Naoto out of the house, is starting to come around. But when the sisters start getting jealous of one another, will Naoto be able to keep everyone happy?
