[Runa] Koi o Hakaseru Saikou no Jyouken

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.

Yaoi (やおい) refers to male-male romantic or sexual content created primarily for a female audience. In doujinshi, yaoi works feature relationships between male characters and span a wide range from soft romance to explicit content. The genre has its own rich ecosystem of tropes, character dynamics, and artistic conventions. Yaoi is distinct from 'bara,' which is male-male content created by and for gay men. Common related tags include 'males only,' 'seme,' 'uke,' and 'anal.'

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.'
