(CCFukuoka28) [Kirsi Engine (Kirsi)] Muttsuri Shoukai ni Youkoso (Baka to Test to Shoukanjuu) [English] [mysterymeat3]

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.

Stockings (ストッキング) is a highly popular fetish tag focusing on thigh-high stockings, pantyhose, and similar legwear. This tag has a dedicated following due to the aesthetic appeal of stockings in illustration — artists often use them to accentuate leg lines, create contrast with skin, and add visual texture. The tag covers various styles including thigh-highs, garter stockings, pantyhose, and knee-highs. It appears across all genres and is often paired with 'sole female,' 'big breasts,' and 'schoolgirl uniform.' Some artists are known specifically for their detailed stocking artwork.

Shotacon (ショタコン) refers to content featuring young or young-appearing male characters. The term originates from 'Shotaro complex' (after the character Shotaro from Tetsujin 28-go). In doujinshi, this tag indicates the presence of youthful male characters in suggestive or explicit scenarios. Content ranges from innocent to explicit and is a significant demographic category. The tag is the male counterpart to 'lolicon' and often appears in yaoi (male-male) content or in heterosexual scenarios with older female partners.
