[Chikaishi Masashi] Kinbo Inran

Anal intercourse is a common sexual act tag in doujinshi. It appears across nearly all genres and demographics, from vanilla romance to extreme fetish content. The artistic depiction ranges from realistic anatomy to highly stylized presentations. This tag frequently co-occurs with tags like 'nakadashi' (internal ejaculation), 'big breasts,' and various body-type tags. Some artists specialize in anal content, developing signature techniques for depicting the act. The tag covers both consensual and non-consensual scenarios depending on accompanying tags.

Bondage (緊縛, kinbaku) is a fetish tag covering restraint and bondage scenarios in doujinshi. This ranges from simple rope bondage to elaborate suspension scenes. The artistic treatment varies from realistic kinbaku (Japanese rope bondage) to stylized fantasy restraints. The tag covers consensual BDSM scenarios as well as non-consensual restraint (when paired with 'rape'). Related tags include 'collar,' 'handcuffs,' and 'femdom.'

Incest (近親相姦) refers to sexual content between family members. In doujinshi, this commonly involves siblings, parent-child relationships, or other familial pairings. The tag covers both blood-related and step-family scenarios. It's one of the most common narrative frameworks in doujinshi, often used to create dramatic tension or taboo appeal. Related tags include 'sister,' 'brother,' 'mother,' and 'father.'
