[MadBull] 和睦的姐弟 （个人汉化）

Big breasts (巨乳, kyonyu) is one of the most iconic body-type tags in doujinshi and manga. It refers to female characters with notably large, exaggerated breasts that often serve as a central visual element. Artists typically emphasize size, weight, jiggle physics, cleavage, and breast-focused activities like paizuri (titjobs) and breast play. This tag spans nearly every genre — from vanilla romance to hardcore fetish content. The artistic treatment varies widely: some artists favor realistic proportions while others push into exaggerated territory. Related body-type tags include 'huge breasts' for extreme cases, 'small breasts' for the opposite aesthetic, and 'paizuri' for breast-focused sexual acts. The tag often appears alongside 'sole female' and 'nakadashi' in heterosexual content.

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.'

Sister (姉妹/お姉さん) refers to content featuring sister characters. This tag covers both older sisters (ane) and younger sisters (imouto). It's commonly paired with 'incest' for blood-related scenarios or can stand alone for step-sister or non-related sister figures. The tag is one of the most common character relationship tags in doujinshi.
