(C71) [Gambler Club (Kousaka Jun)] Sex Shiyo (Chokotto Sister)

Lolicon (ロリコン) refers to content featuring young or young-appearing female characters. In doujinshi context, this tag indicates the presence of petite, youthful female characters. The term originates from 'Lolita complex' and is a significant demographic category in Japanese fan-made works. Content with this tag ranges from suggestive to explicit. It frequently appears alongside tags like 'small breasts,' 'defloration,' and 'schoolgirl uniform.' The tag is distinct from 'shotacon' which features young male characters.

Futanari (ふたなり) refers to characters with both male and female sexual characteristics — typically female-presenting characters with a penis. This is a significant genre in hentai with its own dedicated audience. The tag covers a wide range from characters with both sets of genitalia to characters who are essentially female with male genitalia. Artistic treatment varies from realistic to highly stylized. Related tags include 'males only' (for futanari-only content) and 'yuri.'

Yuri (百合) refers to female-female romantic or sexual content. Unlike 'lesbian' which implies real-world orientation, yuri is a genre term specific to Japanese media. The content ranges from soft romantic tension to explicit sexual scenes. Yuri has its own rich ecosystem of tropes and character dynamics. Related tags include 'futanari,' ' ffm threesome,' and 'sole female.'
