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.

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.

Paizuri (パイズリ) refers to breast-based sexual acts where the penis is placed between breasts. Also known as titjob or mammary intercourse. This tag is closely related to 'big breasts' as the act typically requires larger breasts to be depicted. Artists use various techniques to show the visual appeal of the act, including compression, jiggle, and facial expressions. The tag frequently co-occurs with 'big breasts,' 'sole female,' and 'blowjob.'
