Ass to mouth (ATM) is the most beautiful sexual act ever invented, and it is the ultimate display of love. There are only two kinds of people out there: those who have convinced themselves that they are loved, and those who have stuck their ass-covered cock into their lover's mouth. Talk is cheap, and anyone can say, "I love you". But to accept your lover's cock into your mouth, knowing that it's covered with your own ass juices—that's a genuine demonstration of love, one that can't be faked.
Let's be realistic: there is no way a non-submissive woman would let you ATM her, and there is no reason she should. ATM is perhaps the most degrading sexual act in existence, and you should never suggest it to a woman whom you know is not into submission and degradation. Unless, of course, you want to break up a relationship, for in that case nothing is better than to pull your cock out of your girlfriend's or wife's ass and offer it to her as if it were the most natural thing in the world. The relationship will be over before her ass juice dries on your cock. This article therefore refers only to slaves.
What is it that makes ATM such a wonderful sexual and emotional act? Why is it the most beautiful of all sexual acts, the thing that brings a master and his beloved slave so close together? One might argue that oral sex on a cock that just came out of an ass doesn't feel any better than oral on a clean cock, or on one that came out of a pussy. So, what's the allure of the ATM?
Those who ask that question miss the point altogether. ATM is beautiful and sexy precisely because it serves no purpose other than to humiliate and to degrade. It is the ultimate display of love: the sucking of the ass for no purpose whatsoever. Every time Molly sucks my ass-covered cock, I feel so close to her, so in love with her, so one with her. Nothing in the world can come close.
To understand the beauty of ATM, we must first understand human anatomy. Mathematicians say that the human body is topologically equivalent to a torus. A torus is a mathematical shape that is commonly known as a doughnut: a three-dimensional structure with a hole. The human body contains a tube that runs from the mouth, through the esophagus, the stomach, the small and large intestines, the rectum, and finally the anus. This tube constitutes the hole. Although geometrically the human body and a doughnut are very dissimilar, topologically they are equivalent because they both have exactly one hole or tube. So, sticking your cock in a woman's ass and sticking it in her mouth constitutes sticking your cock into the same hole, but from different directions. Think about it for a minute. It's beautiful.
That tube, which begins at the mouth and ends at the anus, represents a process of degradation and dirtification. It begins with the mouth, which we commonly consider the cleanest part of our bodies, and ends with the anus, which secrets disgusting, smelly feces. The entire process food undergoes as it goes from mouth to anus is a process of degradation. This is precisely the process the slave undergoes when the cock or some object goes in the other direction. As the food is degraded from mouth to ass, so is the slave is degraded from ass to mouth.
Everything described in this article works for male slaves as well as for females slaves, since the pussy and breasts are nowhere mentioned in any significant way. My only experience is with female slaves, so I shall refer only to them, or specifically to Molly, my beloved longtime slave.
But before we get into the technicalities, let's get something clear: ATM is not about scat. If you're into feces, then you've come to the wrong place. ATM, when done properly, should never, ever involve the appearance of any fecal matter—on the cock, in the rectum, or anywhere else. ATM is about domination, humiliation, degradation and control, not about feces.
This naturally means that ATM requires quite a lot preparation. It's the only thing that's bad about ATM—it can't be done spontaneously. The cleansing process begins with the slave taking a long dump to remove whatever fecal matter can be removed naturally. Then, it's enema and douche time. There are plenty of products on the market, and you should choose whichever one works best for your slave. They all work in essential same way: a hose of some sort is inserted into the rectum and then releases some cleansing liquid or gel. The slave then sits on the toilet and pushes is out as if it were feces. The process can be repeated as many times as necessary. When that process is complete, the slave takes a shower in which she puts the shower head against her anus and turn on the water at maximum flow. She should spread her ass open with one hand and aim the showerhead with other to achieve best results. There is also a simple device that connects itself to the showerhead and injects soap into the current of water. It's cheap and easy to install, and I highly recommend it.
Next, you need to choose the proper lubricant. I'm assuming you're using a lubricant because I can't imagine going up Molly's ass unlubricated. It can cause anal and rectal damage, and it will probably feel awful on my cock. There are two major types of anal lubricants: water- and oil-based. The oil-based lubricants lubricate better and almost never dry out, but they are messy and sticky, they taste terribly, and they are hard to clean. For ATM, you should always use a water-based lubricant. The brand is up to you, and there are lubricants in several flavors, so if you want to let your slave taste a mix of ass and strawberry, give one of those a try.
If you pull the cock out of your slave's ass and fecal matter is visible on it, then your slave screwed up the cleaning and you now have a decision to make. One way to deal with it is to shove your cock in her mouth anyway, thus forcing your slave to eat her mistakes. I never do that with Molly because it's disgusting and she might get sick. Instead, I just stop and wash my cock—and then I inflict a punishment so severe that it guarantees she won't make the same mistake for a long, long time. The last time it happened was months ago, and Molly had to spend six hours on the Japanese horse with a giant plug in her ass. Her screams of pain were so heartbreaking and sexy that I came on her face five times in those six hours, and she still shudders when I mention that day. She's been clean ever since.
ATM doesn't necessitate a cock going from ass to mouth. One can transfer almost anything from the rectum to the mouth. My favorite is a pacifier-shaped butt plug. It's pink, it has a small ring on the back side, and it comes in a set of three sizes. I love sticking it in Molly's ass because it makes her anus look just like a mouth holding a pacifier. Then I remove it from her ass and into her mouth. Oh, how cute she looks with the pacifier/plug in her mouth!
When I'm in the mood, I tie a lanyard to the ring of the plug and put it around Molly's neck. She walks around the house like that all day long and whenever I want her to shut up, I just tell her to suck on her plug.
The plug also allows for a continuous ATM action. I stick the plug in her ass a few minutes before we begin, and then I remove it out of her ass and into her mouth. I then fuck her ass with the plug in her mouth. She must not bite into it, and she must not drop it. If she drops it, she gets punished later. After I fuck her ass for a few minutes, I switch plug and cock and I fuck her mouth with the plug back in her ass. Then I switch again, and again, and again. That way, at any given moment she is sucking on something that just came out of her ass.
Another way to do it is to use two plugs and to rotate them between her ass and her mouth. Molly looks so charming on her hand and knees with one plug in each side of the hole in her torus. It's like she has a butt plug rotisserie running through her body. Every few minutes I rotate the plugs and give her a fresh feeling of ass in her mouth. I love masturbating to that scene.
Although I've never tried that with Molly, those who are into threesomes and orgies can do quite wonderful things with ATOM—Ass to Other's Mouth. Stick a cock or a plug into one girl's ass, then into another girl's mouth. Let them taste each other in the most intimate way possible. Before you begin, you can also have them clean each other. It's much more convenient when you let someone else do that for you.
There are plenty of other things that can go into your slave's ass and then into her mouth. Your fingers can make an excellent introduction to ATM for the beginning slave. Just insert them, one by one, into your slave's anus, and gently scrape the rectal walls. Then, slowly and sensually insert them into the slave's mouth, and have her lick her ass off your fingers. Unlike other acts of ATM described here, this one is gentle and sensual.
It doesn't matter how you do or what you do it with, as long as you do it. Just stick something in your slave's ass, and then have her suck on it. You will feel the love in her mouth instantly.
