"my Princess is AMAZING at oral sex. She deep throats and swallows, frequently. Maybe i can convince her to post here. i also REALLY enjoy eating Her pussy too, but i don't think that is what you are wanting to hear or learn about. Best of luck to you in pleasing him." --Strypi's Beast

Why, thank you, my darling! I love pleasing you in this way!

OK, here goes my two cents...I am writing this without having read any other response here.

First of all, you don't want to eat prior to any deep-throating activity, until you've gotten your gag reflex under control...

You have to learn to take tiny breaths in between strokes. Ask your Master to go slowly at first so that you can work on your rhythm. There will be times that you can't take a breath, so you want to always be prepared for that.

The easiest way mechanically to take a cock all the way is to lie on your back and let him on top...this needs to be experimented with, there are many variations on this that can make things easier as well. Google throat-fucking and watch the video clips that you find. It's amazing what you can learn that way. You can also see that the things that happen during such types of oral sex are normal and you won't be so embarrassed by some things!

If you happen to scratch the skin with your teeth or bite and break the skin, get antibiotic ointment and alcohol going quickly! Keep it covered and watch it closely for signs of infection. If you see redness and swelling, get to the doctor!

Speaking of teeth...
Another trick that I have learned is to use your hand to hold your teeth out of the way, sort of like an open-mouth gag. stick your pointer finger just behind your front teeth, and wrap your hand around his cock. Sorta like a combo hand job/blow job, if that makes sense...It helps to get deeper without the fear of teeth causing harm. It also helps me to not gag if I am sensitive, and holds your mouth open wider for a deeper penetration. This trick will also create a wonderful sensation for your Master!

The easiest way to swallow is to have him cum in your throat, till you get used to it.

Hope some of these tricks help. You will just have to experiment. I hated giving head years ago, but I really enjoy it now. Sometimes, I would rather be fucked in the throat than anywhere else!
