How to undo my boyfriends pants with my teeth?

I know this is kind of a silly question... But I was joking around with my boyfriend one night and i said "Well if you're wearing a belt it makes taking your pants off with my teeth a little hard." and he just kinda laughed about it and we moved on, then a bit later he said "You know, that would be really hot. I don't know why, but the thought of you taking off my pants with your teeth just seems really y." and, I'm a virgin, and I don't plan on doing anything with him for quite awhile. I DO intend on him being my first. But when the time comes I'd like to know how to do this... Obviously he wouldn't mind if I did it normally, But I really want to try it orally. I can't find anything on google but one article on taking ALL of a girls clothes off with your teeth and it didn't even involve pants- Please help? And PLEASE don't say "You should save yourself! don't have !" Because as i said, I wont be doing anything for a long time, and when i decide to, It would only be oral at first. Me and my boyfriend are in a maningful relationship, we've talked about it, and he said that he misses , yes, but he would miss me even more if i ever left, and that he would gladly wait till I was ready.
