 If you liked
Bible Black: Imari Ryoujoku Genba

 ...then you might like
Nuresuke JK Ameyadori Rape

Both animations involve a surprise assault by a man on the female protagonist. Nuresuke JK Ameyadori Rape is a more fleshed out hentai than Bible Black: Imari Ryoujoku Genba which is only a short scene. However the tone is very similar. If you like one you will probably enjoy the other.
