Hardcore 3D hentai games & animations from Japan — picked for how well they actually work, not the story

All works are sold on DLsite, Japan's largest doujin (indie) store, which has an English interface. Payment options for overseas buyers are limited (Visa and Mastercard have not been accepted since 2024), so check DLsite's payment page for what works in your country before you pick something. Videos are usually MP4 files you download and keep; games mostly run on Windows, so try the free demo (trial version) first when there is one. Japanese-only games can still be played with a machine-translation tool, but check the store page before buying.
