Edu­ca­tion is an integ­ral part of our lives. When indul­ging in some­thing out of the extraordin­ary, like sky­diving, canyon­ing or BDSM it pays off to be well pre­pared. In this post I will try to exam­ine the ana­tomy of your slave’s sphinc­ter, pay­ing atten­tion to the mech­an­ics involved to let it func­tion prop­erly. By under­stand­ing how nature had inten­ded the asscunt to work, you will bet­ter under­stand what train­ing might work best for your slave to more quickly and eas­ily enjoy use of her asscunt. This is not a com­plete ana­tomy les­son, we will focus on three main parts:

• External Anal Sphincter
• Internal Anal Sphincter
• Anus

To bet­ter illus­trate the areas we are going to cover, please study the pic­ture to your left. Click­ing on the pic­ture will enlarge it and offer you a detailed view of the areas we will be study­ing today.

Dif­fer­ent Masters…

Even though internal and external sphinc­ter are mostly com­posed of the same fibers and both behave as muscles, there is a fun­da­mental dif­fer­ence between them. The external sphinc­ter is a con­sciously con­trolled muscle, your slave’s brain has dir­ect influ­ence on that muscle, she can con­trol it. The internal sphinc­ter is con­trolled by the veget­at­ive nervous sys­tem and thus mostly removed for your slave’s con­scious con­trol. As small chil­dren we learn over time how to con­trol our bowel move­ment by exert­ing con­scious con­trol over the external sphinc­ter. The external sphinc­ter is not fully detached from the work­ings of the inner sphinc­ter.
It has a nat­ural tend­ency to bet­ter relax when the internal sphinc­ter sig­nals that there is a need to release its con­trol, usu­ally this would hap­pen due to immin­ent bowel move­ment. Most con­trol your slave exer­cises over the external sphinc­ter is not con­scious. Through con­di­tion­ing and train­ing the brain has learned not to relax as soon as the inner sphinc­ter urges the external sphinc­ter to do so, rather your slave has to make that a delib­er­ate action once a suit­able spot to do so has been found.

Revers­ing it…

Your slave’s colon has been shaped over thou­sands of years to ensure that some­thing can leave her anus, there was little inten­tion of filling the anus from the out­side. Your slave’s inner sphinc­ter is mostly pres­sure sens­it­ive, com­bined with the nerve inputs from the veget­at­ive nervous sys­tem, the muscle will sig­nal your external sphinc­ter to relax, only it believes that there is a need. Through care­ful train­ing you can help develop that need. Two of the most well known tech­niques are:

1. Con­sciously push­ing down, sim­u­lat­ing bowel move­ment — The arti­fi­cial pres­sure cre­ated in the colon will help the internal sphinc­ter sig­nal the external sphinc­ter to relax, thus mak­ing it easier to pen­et­rate the external sphincter.
2. A filled blad­der — When your slaves blad­der emp­ties com­pletely, the pel­vic floor muscle tight­ens and the sphinc­ter squeezes shut. Keep­ing the blad­der filled may help with ini­tial train­ing as it builds addi­tional internal pressure.

Loc­at­ing Pleasure…

Very sim­ilar to the ana­tomy of the cunt, most of the nerve end­ings respons­ible for build­ing sen­sa­tions due to stim­u­lus to your slave’s sphinc­ter are situ­ated at the very end, close inside the area near the end of your anus, your anal fis­sure and the tis­sue above the internal sphinc­ter. The dens­ity of nerve recept­ors in your slave’s anus is extremely high. Mostly because her body needs to be able to clearly under­stand what type of bowel move­ment is to be expec­ted. Research also sug­gests that the amount of recept­ors increases as you get older.
Once the ini­tial lin­ing of recept­ors has been passed the anus mainly responds to pres­sure. For females the pres­sure is often trans­lated towards the thin mem­brane which sep­ar­ates her vaginal chan­nel from the colon.

Train­ing…

Put­ting the know­ledge gained from the dis­cus­sion above to good use we should come to some con­clu­sion.
As the internal sphinc­ter is not dir­ectly con­trolled by your slave’s mind, you should make sure that her body is in a state of relax­a­tion and that she can feel safe whenever you aim to train her asscunt. This addi­tional con­di­tion­ing to accept her train­ing will make it easier for her body to allow and wel­come the stim­u­lus to her asscunt. Mak­ing sure that she is well edu­cated about her body, her asscunt and all the inhib­i­tions and fears around asscunt sex will make your efforts in train­ing her much easier. Remem­ber that you are inter­ested in long term train­ing which should gradu­ally build a need in your slave for stim­u­la­tion of her asscunt.

Toys…again

Tak­ing into account what you have read above, it is cru­cial that you pick the right shape of toy to com­mence with your slave’s ini­tial train­ing. Tra­di­tional toys such as rectal dilator kits and anal trainer kits take into account that train­ing devices need to have a fairly long, nar­row end and a bulbous tip. The nar­row end ensures that the internal and external sphinc­ter are gradu­ally expan­ded, while the bulbous head ensures there is pres­sure against the inside of the colon, for­cing the internal sphinc­ter to relax more nat­ur­ally. As you might recall, pres­sure against the colon wall is the main indic­ator for the inner sphinc­ter that there might be bowl move­ment, which then allows the inner sphinc­ter to be relaxed urging the external sphinc­ter to do so as well.
