Blowjob doesn't qualify since it doesn't reach 25% of the gallery (by a very small margin tho). Having that in account, whoever tagged focus blowjob is an idiot. Same can be said about nakadashi but the "focus" part in the tag name makes it quite obvious when it should be used, or at least gives you an idea even if you didn't check the definition of the tag or know about "presence rule"
Edit: Didn't notice a bj in page 2 (pages 21-35), so blowjob might qualify depending on if page 11 counts or not
