Blowjob (フェラチオ, fellatio) is one of the most common sexual act tags in doujinshi. It covers oral sex performed on male characters. The artistic depiction varies from realistic to stylized, with many artists developing signature techniques for depicting the act. Common visual elements include drool, tongue detail, eye contact, and depth indicators. The tag appears across virtually all genres and is frequently paired with tags like 'ahegao,' 'big breasts,' and 'sole female.'

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.'

Kissing (キス, kisu) is a romantic/sexual act tag covering various types of kisses. While seemingly simple, kissing scenes in doujinshi can range from tender romance to intense passion. The tag helps readers find content with romantic elements rather than purely physical encounters.
