The Sissy Experience
Hm? You're not taking it very deep you know. Have you ever deepthroated a cock before? No? That explains it. If you have a dildo, now is the time to grab it. Failing that, simply use a couple of fingers(wash your hands beforehand, we don't want germs in there). Push it into your mouth, slowly, until it reaches the back of your throat. Now, move it downwards until you feel your throat tighten up and try and expel it, as if you're choking. That's your gag reflex, and good sissy whores train to suppress it. Try holding your dildo or fingers there for a few seconds. Don't worry, you have more than enough air to do this. You may feel like you want to vomit, this is perfectly normal as it is a part of the gag reflex. Take it out if you're about to throw up though.
I recommend you practise this for a while before continuing.
