[Ponpon Itai] Imouto wa Ko-monki!? | My Little Sister's In Her Anal Stage?! (COMIC LO 2014-01) [English] {5 a.m.}

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.

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.

Glasses (メガネ, megane) is a costume/accessory tag with a dedicated following in doujinshi. Characters wearing glasses — whether thin-framed, thick-rimmed, or sports glasses — appeal to a specific aesthetic preference. The tag covers all types of eyewear and is often associated with character archetypes like the 'meganekko' (glasses girl). Artists use glasses to add visual interest and character personality. The tag appears across all genres and frequently co-occurs with 'sole female,' 'big breasts,' and 'stockings.'
