I was checking some non-hentai (一般漫画) mangas on
http://www5e.biglobe.ne.jp/~poko2/. NTR in many works is too nuanced for me (as in The Five Star Story) or less rage inducing, because protagonist is too popular (so one NTR-ed girl doesn't really hurt him), but I've found a few more or less polished gems (but unfortunately - untranslated):
- Ai Don't Koi (愛DON'T恋) - school romance, NTR type A (bonus points for changing girl into a prostitute), NTR type B (harder hitting, because later protagonist tries to be more faithful)
- Kyoushirou 2030 (きょうしろう2030) - a crazy story in a dystopian future (sex, over the top violence with a pinch of sillyness). Mainly NTR type C, but it's nice to see a woman who doesn't change into a bimbo, but have a strong will needed to wait for an opportunity to turn tables on her blackmailers (as in Inomaru mangas)
- Naniwa Tomoare (ナニワトモアレ 全) - thug life, racing, NTR type C with long-term consequences (depending on your definition you could add NTR type A, but it's rather love triangle than an asshole seducing protagonists woman)
- Mujina - ninjas, NTR type C, not so great, but it was funny to see what author means by a happy end
Almost NTR:
- Okusama wa Joshi Kousei - a student-teacher relationship, a great art, some situations that could easily lead to infidelity, rich imagination of a main girl (in the translated part of manga you can see a what-if scenario with a naughty electrician), a blackmail in a final volume
- Mahou o Shinjiru Kai? (NAKAJIMA Fumio) - short school romance with an agressive rival and a weakly defending herself girl

Recently I was checking older NTR games (searchin vndb), but one is still elusive for me -正義の教室 (Seigi no Kyoushitsu by Flyingshine Ken). Anyone have seen any working links (I know that there is a CG set on a sadpanda, but I'm intersted in a game)?
