Yeah, I used to pride myself on not having a gag reflex. Then I found out that was only because I was always the one controlling the depth and speed. When I started fantasizing about my man fucking my throat and wanting to choke and gag, get tears in my eyes but having him keep shoving my head down... you know... I guess this is from watching so much porn! Anyway... I started asking for this and quickly found out that I do INDEED have a gag reflex! I liked the choking and gagging, never thinking I would ever actually puke because I am the type of person who NEVER pukes. In fact, that is how I knew I was pregnant, because I puked, and that was the one and only time that I have puked since being a teen and binge drinking.
So, after many nights of trying this new found "throat fucking" that we both had started to enjoy so much, bile unexpectedly rose up in my throat and filled my mouth. What is EVEN worse... I ended up just swallowing it, without even thinking. It just happened so fast. He kinda looked down at me and said " Did you just....? ", not even wanting to finish the sentence or say it out loud! The horrified look on his face made me just start laughing. So then we both laughed about it for a good long time and ended up having sex anyway, with out any kissing of course!
