@marx I understand your points, but still the issue of then needing other similar subtags exist. Generally I think we should avoid using tags that just combine 2 already existing tags. Because then yeah, technically if you look for both tags at the same time you get different results than using an actual combined tag, but then we would need an absurd amount of combined tags. And the main point is that while you get other results that you might not be looking for, you still get all the results you're looking for, that's what tags are for

There are many galleries which include inflation from oral but are not tagged under gokkun + inflation, such as #638171 | Loli Baba Okaa-san wa Oshi ni Yowai 10 | 6,014 , #651800 | umaibeany hd art | 3,315 , and #315177 | SakuMyon Kinki Scatolo Hen | 2,199 (scat warning). There are also edge cases, eg when there is inflation, but the cum is trapped in a condom #140706 | Bitch na Mutsu-chan no Saishu Ninmu | S… | 16,739 . Finally, the liquid in question may not be cum - it might be pee, or a large mass of tentacles, for example. This is a useful tag, seeing as inflation & stomach deformation from oral is a trend that growing steadily (albeit slowly), similar to burping (see works by https://nhentai.net/artist/dekosuke-18gou/) in recent years. mizumizuni (https://www.pixiv.net/en/users/7026506) exclusively draws deepthroat art, and frequently depicts inflation from large amounts of cum, along with stomach deformation from oral. Lastly, https://nhentai.net/artist/lbl/ is another artist who often depicts inflation from oral.

This is distinct from gokkun + inflation, since both often occur in different scenes. Out of 182 galleries, at least 26 depict inflation from oral, namely: #71594 | Nikuyokugami Gyoushin - New carnal stor… | 6,310 #142589 | Scarlet Hearts | 138 #222550 | Tora ga Nezumi ni Kateru Wake ga Nai!! | 3,137 #251922 | Backup no Nai Jakushou Master no Maryok… | 3,688 #251924 | Backup no Nai Jakushou Master no Maryok… | 36,163 #251639 | Backup no Nai Jakushou Master no Maryok… | 2,574 #348362 | Ibaraki Douji no Reiju de lovesbox | Us… | 28,455 #380891 | Athletic Play | 12,252 https://nhentai.net/g/389641 https://nhentai.net/g/392113 https://nhentai.net/g/392114 https://nhentai.net/g/399077 https://nhentai.net/g/400055 https://nhentai.net/g/402485 https://nhentai.net/g/404967 https://nhentai.net/g/460939 https://nhentai.net/g/470436 https://nhentai.net/g/488142 https://nhentai.net/g/498443 https://nhentai.net/g/505057 https://nhentai.net/g/552956 https://nhentai.net/g/560441 https://nhentai.net/g/583437 https://nhentai.net/g/599373 https://nhentai.net/g/615387 https://nhentai.net/g/639356 Arguably, a small but substantial percentage makes an ideal candidate for a new tag.

'Cumflation' already exists, and also 'gokkun + inflation' is the same.

@Osamu09 is right, this just gonna add so much sub-tag, not worth it

you could just search for gokkun + inflation. Otherwise then we'd need to add "inflation from anal" and "inflation from creampie" or something
