A guide to deep fisting

This is a guide to deep fisting only. If you can't fit a fist or two in your ass with ease then don't bother reading this. Get your toys out and go start stretching.

However if you feel comfortable being fist fucked in the ass and looking to go deeper then read on.

Before I get started with the technicalities I have identified four key aspects to deep fisting.
Patience, communication, cleanliness and lubrication.
I think they are all self explanatory but will explain in a little more detail.

Patience, probably the most important aspect. Don't expect to be elbow deep in your partners ass over night. For some this will take years. Rushing will cause pain and ruin the experience or worse yet, cause some kind of internal injury. I'm sure we all agree that turning up to the emergency ward and having to explain why we can't stop bleeding out the ass is something we all want to avoid. On that note. A little bit of blood is not uncommon. As long as it is bright red it's not such a problem. The rectum and colon are filled with small blood vessels which are easily damaged. It's probably a good idea to stop but some people go on if there is only a little bit and it is not getting worse. However a darker red colour may be a problem. Stop immediately and monitor. If the bleeding does not slow down a trip to the doctor may be in order. So take your time, don't rush and make sure everyone involved is in the mood and the setting is right.

Communication, is obviously an important one. As much as you may like to gag your slave and force your arm inside his ass to the shoulder this may not be a good idea.
It's very important for both the fister and fistee to 'talk their way through' what's going on. Keep in mind as a beginner to deep fisting dirty talk about fist r****g your slave to the elbow or something similar may not be such a good idea. You want to create a relaxing environment without putting pressure on the fister/fistee to perform. Any kind of anxiety or stress will cause the sphincter to pucker right up. This is why calm, reassuring and informative communication is good for beginners. To state the obvious any kind of pain or discomfort should be expressed. Even from the fister, if they can feel the fistee is very tense and not relaxed they need to express this rather than keeping it to themselves and pushing on.
I do not like safe words for beginners because they are usually used whist the fistee is at their limit and can not take any more. Constant communication is best.

Cleanliness, this is pretty self explanatory. Nothing's more disappointing than getting in the mood and with everything setup to find your slaves bowels are not clean. It can be dangerous also as there may be abrasive or sharp things in your shit which could scratch or tear the linings of your colon.
Anything past the rectum will require proper preparation which can be time consuming and require discipline and patience.
I will not go into the techniques now as this is a whole different topic.
But it is very important to remove all solids from your sigmoid colon before any kind of depth play.
Clearly normal hygiene is required so even though you may be planing to ram your fist up your partners shithole you still need to clean your hands well to prevent any infection and vice versa afterwards.

Lube, well this is another obvious one. Enough is never too much. You can fill your slaves ass with a gallon of lube if you wish. The more the merrier! Plus all the noises and slopping around are always good fun. You need a lube that lasts as fucking someone with you arm probably creates the most friction out of any sex act.
We personally like J-lube which you can make yourself to your own consistency. It's also nice and easy to clean being water based.This is what we have been using in our latest videos. Try and get it as far into the ass as possible, we use a 60ml syringe which can be picked up at your pharmacy.
Others prefer crisco oil which we are not such a fan of just because it's harder to clean.
There are more and more lubricants on the market that are designed specifically for anal fisting. I'm not that familiar with them but Im sure they will be great. However most are not cheap. Just google it and you can find the many brands around.

Ok so now we can get into the nitty gritty.

Firstly I think one should consider the anatomy of the body. From the rectum, the colon passes into the sigmoid colon, then goes up on the left inner side of the body (from the fistee's point of view), next takes a turn across to the right side and finally goes down again. The medical terms (ascending, transverse and descending) indicate an opposite direction, but a fister thinks different, of course.
Keep in mind everyone's body is different. For some people it may be a physical impossibility. Particularly if the fister has big hands. Observe the image below. The instance in the top right demonstrates the easiest path to follow while the bottom two are much more bent making any kind of deep penetration more difficult.
The first image represents what I think is the more common shape. A sharp "S bend" just after the rectum, hence the name sigmoid meaning S shaped. Keep in mind it is all quite flexible, the more you fist deeply and the deeper you go the more the colon will begin to straighten out and the easier a brutal fisting will become.
You can tell from our vids that the strap on needs to follow a relatively straight path, my Slaves colon is nice and straight after all our training.




Most fisters/fistees manage to enter the rectum with their hands (they wouldn't be fisters/fistees otherwise). After this point the fun starts. To enter the sigmoid colon there is a small opening much like your asshole. I like to refer to this as the second sphincter. Like your asshole it is a muscle a lot like a rubber band. It can be too tight even to get a finger into, but with some practice, patience and the right frame of mind it can become flaccid and relaxed, thus able to fit much more than just a finger or two.
I recommend starting with a small but long double ended dildo. A common size which I recommend is 18" long by 1.5" thick. Soft is good but it needs a certain degree of rigidity. The one I trained my slave with is a jelly crystals double trouble 18" double dong. But there are many out there that are similar (I actually find this one a tad too firm.)
You can start by having the fister play with the second sphincter with their fingers. Gently applying pressure and working one or two fingers in and out until you can feel the muscle relax. At this point you can start stretching more either with more fingers or a toy, remember to use plenty of lube! A good toy to use at this point is the American bombshell Rockeye. My slave likes this one as it's easy to get into the sigmoid colon then good for stretching it as you take more and more of the toy in.


Getting to the point where the fistee is able to relax their second sphincter and stretch it more and more, comfortably may take you hours or even days. You may need a few sessions to become accustomed to penetrating the second sphincter with ease both for the fister and fistee. Just remember patience is key, forcing or rushing this will not only ruin the experience by could hurt your slave.

So this is now where the next step and the proper deep fisting begins.
Entering the sigmoid colon with your hand is quite a milestone, you will be well and truly on your way to some elbow deep fist fucking action.
Now that the second sphincter is trained to relax and take larger objects it's time to get your hand fully past it which is what everyone's been waiting for.
Similar process to before continue working fingers into the second sphincter until it relaxes and your Slave is comfortable. Once you feel you can get all five fingers in create a duck shape with your hand and start pushing the knuckles through. You may need to fuck the second sphincter at this point up to you knuckles slowly stretching and going deeper thrust by thrust. Communication is key at this point as is lube, make sure your using plenty.
Once you are able to push past the knuckles the rest of your hand will almost be sucked into the sigmoid colon. This is an amazing feeling for both. My slave loves it so much I punch fist him as hard and fast as I can through the second sphincter but this will take plenty of time and practice. He is now so well trained I can get both my hands in the sigmoid colon about 3" past the wrist, this is quite extreme though!

Once you are in the descending colon you can push your hand/arm deeper and deeper whilst keeping it relatively straight. Remember the pictures, the descending colon is on the left side of the fistees body so you should aim your hand to follow in this direction. Up to the point where you are about elbow deep in your slaves ass.
At this point you will have reached the limits of the descending colon.
In most cases this is as deep as you can go. Entry into the transverse colon now is tricky and requires that you bend your hand at the wrist and find the opening to the transverse colon. To go further, the fisters hand should make an angle at some point to follow the the natural form of the colon. As a wrist can only bend inwards, it makes sense for the fister to use the left hand when the fistee is on all fours and the right hand when he is on his back.

It's worth mentioning that I find having my slave on all fours is the best position for depth play. The organs are not weighing down around the colon for one and with the ass high in the air and torso tilting downwards they also sit higher in the body allowing more room for arm to glide in.

In my videos I only ever fist fuck my slave in the descending colon. As you can see with training he can take my arm past the elbow.
I have over time been slowly teasing my way into his transverse colon but for now anything much deeper that the elbow is a while way off.

So there you have it, my guide to deep fist fucking whom ever is lucky enough to take your fist.

If you are looking to go shoulder deep which is just natural :) well join the club, this is a whole different ball game!
