(Reitaisai 12) [Saihate-Kukan (Hino Hino)] Amanojaku no Kowashikata (Touhou Project)

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.

Double penetration (DP) is a sexual act tag indicating simultaneous penetration of two orifices. In doujinshi, this typically involves vaginal and anal penetration simultaneously. The tag is often found in gangbang or multi-partner scenarios. Artists use various techniques to depict the act, often with emphasis on the character's reaction. Related tags include 'gangbang,' 'anal,' and 'multiple male.'
