Not too much to say on this one, so I’ll keep it short.
If you ever found yourself watching Railgun and getting in the mood for some Railgun hentai, とある科学の超電マ砲 (A certain scientific super railgun) might be the hentai game for you.

Hentai CGs and scenes

It features about five different heroines, voice acting, and animations.

The games from this creator feature artwork and hentai CGs that are incredibly close to the original anime, so they are worth a look if you’re looking for hentai content on a specific character or series.

The main characters for とある科学の超電マ砲 (A certain scientific super railgun) are: Misaka, and her clone, Saten, Uiharu, and Kuroko.

Ever wondered what would happen if Kuroko finally got her way?

The main highlights have to be Kuroko finally getting her hands on Misaka and Uiharu getting back at Saten for all the skirt-flipping.
It’s worth taking a look if those scenes, where it hints at it, in the anime ever did anything for you.

In case you were looking for something different, there are alternatives, such a game with over twenty characters, though based more on the characters from Index, and two 3D Railgun Hentai movies.

Where to get their games

The game initially mentioned, とある科学の超電マ砲 torrent downloads no longer exist as the game was released back in 2011. You may be able to find a torrent file to download or direct download links, but they’ll likely be useless. 

So head over to DLsite to get a copy and enjoy.
