The first story focuses on student/teacher relationship, infirmary nurse, to be exact. The female student Aya and teacher Kyou are in a secret illicit relationship, unbeknownst to the rest of the world. In fact, they live together and a tiny apartment. Apparently they've known each other for a long time. There's not much of a story except for a plot that allows them to have lots of sex at different place, at different times, with different clothes. Good old fashion consensual one on one sex! Sex at home, sex at school, sex in the kitchen, hot sex.
Second story starts with a rather refined schoolgirl being interviewed on TV. She had lost her parents, powerful CEO of the Kojin Group, and the interviewer asks how she is coping. She hides her sorrows behind a smile saying that that her elders have been very kind and are helping her out. From there we zoom out into a dark room as the interview still plays on the TV. She's in bondage and chained up hanging with a ball gag in her mouth, squealing, as a fat man pounds her from behind. Her younger brother watches in agony behind a one way mirror. Oh la la!
Apparently she needs to seduce men with various fetishes in order to get favors to keep her company afloat. This allows for a variety of different plays. Elements of bondage, scat, dildo, incest, and NTR can be found.
It's better than the first story but honestly, not much of a story either. However both stories end happily. Nothing that will leave you heavy with negative feelings.
Art and animation in Kojin Jugyou are pretty standard fan fair when it comes to hentai these days. The character design look good, well developed, with out over sized boobs. The animation does have some repetitive frames, but nothing you would complain about. Good angles, extensive sex scenes. The voice castings are good and rather seductive on the female voice acting, yelping like bad little puppies. The dialog is pretty funny at times. "Don't do it Nee-san. Don't let that bastard have your holy water." (referring to her urine) Sound FX really enhanced the experience during sex scenes. I really dig the excessive squishy watery sounds and hip ramming noises. The BG music is rather light and enjoyable. If you're looking for good fap material, this is it. There are internal cum shots and loads of cum that are reminiscent of Yuki Seto's work. In fact if you liked Accelerando, Stringendo, and Stretta, you'll like Kojin Jugyou.
What makes Kojin Jugyou so great is the innocent seductive charm of the female leads and the intensely erotic sex they have with their male counterparts. She teases you, pleads with you in a way that you just can't hold yourself back. Then you go all out, pounding her over and over again until you have nothing left. Perhaps you think you're in control. But in the end, she'll always have her way. In the art of seduction, the female leads in each story are natural geniuses.
