So, you somehow appreciated the boobs of Zokusei and wanted something with a little more plot and a whole lot less diversity in mammary size? Then Asa made Jugyou Chu! is just what the breastician ordered. Somewhat more plot, more large mammaries with a token loli, stupidly perverted situations with a young male and girls his age with an older one for kicks and boobs. It's not nearly as classy as Zokusei and that's just above a skin mag and the characters are just as deep.
