Oh how I love to learn new things... :) I now know that blocking my airway at all when I have the hiccups is a bad idea. I was asked if I would make a clip licking and sucking on a dildo with the hiccups, so its starts out slow. I lick and hiccup, and put it in my mouth and hiccup... But after a few minutes I happen to have a hiccup when its further in my mouth and it kind of created a suction and hurt my chest. I try to recover like a lady, and keep going but after it happens a couple more times I laugh and tell you I can't do it anymore... :)
