[Kichijouji Monaka] Sister Game Vol. 1

Nakadashi (中出し) literally means 'internal ejaculation' and refers to creampie scenes in doujinshi. It's one of the most common sexual act tags, appearing in over 120k galleries. The tag covers vaginal internal ejaculation specifically. In narrative terms, nakadashi often serves as a climactic moment and may be tied to plot elements like pregnancy, impregnation, or relationship escalation. Artists frequently emphasize the visual aspect with detailed internal views (often using x-ray techniques). Related tags include 'impregnation,' 'creampie,' and 'internal cum shot.'

Glasses (メガネ, megane) is a costume/accessory tag with a dedicated following in doujinshi. Characters wearing glasses — whether thin-framed, thick-rimmed, or sports glasses — appeal to a specific aesthetic preference. The tag covers all types of eyewear and is often associated with character archetypes like the 'meganekko' (glasses girl). Artists use glasses to add visual interest and character personality. The tag appears across all genres and frequently co-occurs with 'sole female,' 'big breasts,' and 'stockings.'

Mosaic censorship (モザイク) refers to the pixelation or blurring applied to explicit content in Japanese published works. This is due to Japanese obscenity laws that require censorship of genitalia in published materials. The tag helps readers identify whether content is censored or uncensored. Many doujinshi are published with mosaic censorship and later 'decensored' by fans or released in uncensored versions by the artist. Related tags include 'uncensored' and 'full censorship.'
