Itazura The Animation

These two hentai's are the same in the following ways: Train Rape Vibrators Big breasts Small breasts (joking :D) Finally older woman 

Both have; 1. Molester main character 2. Strong,beautiful and fashionable girls 3. great, smooth and realistic animation 4. more molesting and less actual sex scenes 5. very light censoring Itazura has old animation and is relatively more extreme (humiliation & rape) 

Chikan (train molesting) hentai anime that feature girls who are normally very conservative have sex on the train. In both anime the "MC" is a guy who is so talented at molesting girls that he would always get what he want with women. 

Both have chikans. Moreover, the main male character is quite the same ^^ 

Early 2000 hentai OVA with similar art direction (realistic proportions and detailed figures). The main character is the scheming type. 

Similar perverted/sexual spying on women
