Viper GTS

Originally a H-game that was turned into a Hentai anime.

The game Viper GTS, published by Sogna, was a sequel to a story in an earlier game where a man, Ogawa, attempted to summon a demon to sell his soul for revenge against his tormentors. Instead, he's Distracted by the Sexy succubus Carrera who he summons, and wishes to sleep with her instead; the winning move was to continue having sex until the player is an unconscious husk, so Carrera leaves the player alive and ensouled, since he can't technically say that she kept her end of the bargain.

In the GTS game, Carrera has been imprisoned for failing to collect Ogawa's soul; meanwhile, Ogawa is unable to get his mind off his encounter with Carrera, and decided to summon the succubus again despite the risk to his soul. The plot is complicated by Carrera's rival, Mercedes -- as well as Knight Templar angels who want to break the whole thing up and imprison the devils responsible.

The anime version combines the plot of both games and elements from secondary materials.

Not to be confused with the Dodge Viper GTS.
