NSFW Multiple blowjob and double blowjob

This doesn’t quite make sense to me. Double blowjob has roughly 510 images, and multiple blowjob 279. How is this even possible when double blowjob implies multiple blowjob, and multiple blowjob is a wider spectrum of images?

Tag implications don’t propagate backwards. If they did, it could cause all sorts of headaches.

Sorry for late response.  
I understand that double blowjob -> multiple blowjob but not vice versa, if it were vice versa it would be an alias. I guess some double blowjob images already existed before the implication was made, so I’m manually going through all the double blowjob images and adding multiple blowjob.

Same problem for spreading and spread legs, which I’ll also fix.
