The taste and texture of the mouth that is now yours. You stop braying for a moment, as you realize that mouth is now yours, and you are stuck with it! You try spitting out the saliva-formed muddy grass, but your tongue is so thick and pasted with the stuff.
You roll the tongue around, and make pathetic little brays. You feel sick and nauseated at the thought that you are now in possession of a random dirty animal's dirty mouth, and the taste was even stronger than the odor was! You are experiencing the tastes that animal was experiencing a moment ago! And now there's nothing you can do about it! You try to gag, but a feature of all equines, which includes your new species; donkeys. Cannot vomit. You aren't sure you'd really want to anyway, as you'd then have the stomach acid from a donkey covering your already disgusting sour donkey tongue.
You look down, trying to ignore the filth of your mouth, hoping to see your hand you could use to grab the filth and wipe it out of your mouth. But all that comes into your vision, is the heart-stopping visual of two front legs ending in large black hooves! No hands! No fingers! Just two black mud and shit-covered blocks! Your....HOOVES! Hooves that shouldn't be "yours"! You "feel" that you are now stuck on all fours for the first time.
You feel familiar stirrings in the penis, as you crane your neck to look back along your flank. A fat gray fur-covered barrel of a body that extends far back, and ends in a rounded gray hump. You can make out the outline of a donkey body in the long shadow with the shadow of the ears further out. You can barely make it out, as you find you have poor eyesight.
"So that's it. I'm a donkey now!" "Eerrghh hhhaaww eerrgghh hhhaaww-!" You cut yourself off, with the realization of your inability to speak, and your new obnoxious equipment between you legs really begins stirring with the thought that you're now stuck as a fucking donkey!
Or at least, until you actually fuck as one. The setting you used on the chronovac will keep you prisoner, until you experience ejaculated as a well-endowed male donkey. The thought DOES excite you, as the equipment you are now using begins tingling. You feel the familiar sensations of hormones as a male, even if you are currently of a different species. The sensation you find is still the same, only growing more intense than you're used to.
You begin imagining you will never turn back, in order to spur the penis to greater action. That your stuck with these useless hooves.....uh oh....you realize the hooves you currently possess are useless in gripping the penis! Which means you'll either have to figure out how to masturbate without hands, ooooorrrr.....
The thought disgusts you! You were never really into "beasteality" as such. Just more into self-satisfaction through tortuous, humiliating, and compromising thoughts of the transformation variety. If anything, you're more homosexual and want nothing to do with females. Female vaginas disgust you.
