How to use the capsaicin in hot peppers to make your bottom burn for hours with an exquisite afterglow.


One of the nicest things about a spanking is the afterglow: the warm feeling in your buns after the job is done; the way they become exquisitely sensitive to the touch of the hand or the rub of the underwear; how it reminds you of your punishment when you are fucked doggie-style and his belly bangs against your bottom as his cock dives deep inside you. Surely, many spankees long for a way to make the afterglow last longer or even to make it more intense.

Well, such a method exist. It is based on the creative use of hot peppers or their active ingredient, a chemical called capsaicin. In this article, I am going to tell you more than you ever wanted to know about the science behind the wonderful effects of capsaicin. Then I am going to explain how to use hot peppers to enhance that afterglow feeling to such a level that it may make your spankee regret that you ever read this article.

The science of hot peppers and capsaicin

The molecule of capsaicin

Ever wondered why hot peppers are hot? Not all spicy food produces this burning sensation: garlic, onions, horseradish and wasabi also elicit a strong, sometimes unpleasant “spicy” sensation, but not of the burning kind. The burning sensation of hot peppers is caused by a single chemical, a molecule called capsaicin. Research started in the 90s unraveled why capsaicin makes you feel like you are burning without being actually burnt. Capsaicin, it turns out, binds to a protein called TRPV1 (transient receptor potential vanilloid 1, if you want to know) that is also activated by high temperatures. TRPV1 is present in a population of C-fibers, the nerves that transmit pain from the skin and other organs to the spinal cord. C-fibers with TRPV1 transmit burning pain, so when capsaicin activates TRPV1 it also feels like burning. Garlic, horseradish and wasabi activate a similar protein called TRPA1, which when activated also elicits pain but not a burning sensation. Yet another protein of the same family, TRPM8, is the receptor for menthol and produces the sensation of cold. That’s why menthol feels cool. Fascinating, isn’t it?

Now let’s go back to BDSM. You are being spanked and each slap that lands on your bottom feels hot. After the spanking is over your buns stay warm for a while. Why? Does this have anything to do with TRPV1? Yes, it does. The impacts of the spanking cause a bit of damage in the dermis, the bottom layer of the skin, causing its cells to release some of the metabolites stored inside them, like ATP and glutamate. These activate receptors in the C-fibers (the pain nerves) which in turn release two neuropeptides, substance P and CGRP (calcitonin gene-related peptide, if you need to know), which make the capillaries swell with blood. This is why your bottom turns that nice red. It’s a process called inflammation, characterized by three things: pain, swelling and heat. Some of the released chemicals cause a bit of activation TRPV1, which is responsible for the heat component of the inflammation.

Hot peppers burn in your mouth, because mucosa skin is rich in TRPV1, but do not produce much burning in regular skin. However, if the skin is inflamed that’s a different story: the TRPV1 receptors are already primed by the inflammatory soup of chemicals released from the damaged cells, and capsaicin drives them through the roof. So, if you apply capsaicin to a well-spanked bottom, instead of a nice warm afterglow it will start feeling burning hot. Not only that, the skin will become very sensitive to touch, so a simple caress or the rub of underwear will now feel painfully hot. This is something similar to what happens with sunburn, another form of inflammation. The technical term for when the sensation of touch turns to pain is allodynia.

Is capsaicin dangerous?

By now, you are probably thinking: “do I really want to do this to my bottom?” Well, we do regularly eat capsaicin in the form of hot peppers, some people even in fairly large amounts, so if we are not concerned with putting it inside our bodies why should we be concerned with putting it on our skin? Needless to say, capsaicin makes your skin feels as it is burning, but it does not actually burn you. That is, it produces no tissue damage. Capsaicin is also sold over-the-counter as pain medication to treat arthritis, tendinitis and muscle pain. In comes in touch applicators containing a solution of up to 0.15% capsaicin.

However, capsaicin has also been weaponized in the form of pepper sprays like Mace, which contain from 0.18% to 3% capsaicin. It acts by producing a blinding inflammation of the eyes, burning in the skin, and coughing and difficulty breathing. In people with asthma, this can be deadly. Therefore, just handling capsaicin in a scene can pose a risk for both the top and the bottom. One thing to keep in mind is that capsaicin is not soluble in water and is very soluble in the fats of the skin, so it is almost impossible to wash away. Soap will not do the trick. It is soluble in alcohol, but you cannot apply alcohol to your eyes and I would not recommend putting it in your genitals. You could use a lotion rich in fat, but do not expect a complete wash-off.

What concerns me more about using capsaicin in the scene is that over time it can actually kill or blunt those C-fibers that contain TRPV1. This may be why capsaicin is used as a pain-killer. The end result could be that you develop an iron-butt: buttocks that can endure a good amount of abuse without much pain. You need to decide if this is something you want.

How to use capsaicin in the scene

You have a choice between using hot peppers or a capsaicin solution that you buy at the pharmacy (0.025% is a good dose if you want to start easy). Capsaicin solutions are easier to handle. Peppers are more natural, sexier and artsy. Personally, I prefer the peppers, so I will give instructions for their use, which can be easily adapted for capsaicin solutions.

What you need: a knife, a cutting board, disposable plastic gloves, cleaning wipes and paper towels. And, of course, chili peppers. I recommend green jalapeños, chile de árbol, or similar. Watch out for Thai peppers or habaneros, they are too hot!

Give the bottom a nice spanking on the bare buttocks. Keep in mind that the intensity of the burning sensation will depend as much on the strength of the spanking as the amount of capsaicin. Since the dose of capsaicin is difficult to adjust, especially if you use hot peppers, it is better to pay attention to the spanking. Which means, keep it light. In your first try don’t go beyond a nice uniform pink color on the butt. A five to ten minute spanking with medium intensity should be enough.

Put on the gloves. Using the knife and the cutting board, cut the peppers lengthwise. Get rid of the seeds, which have the larger amounts of capsaicin and tend to get everywhere. Then, using your gloved hands, gently rub the peppers over the pink part of the skin. If you want to do this scientifically, you could use one buttock as the test (it gets the peppers) and the other as the control (no pepper). Be careful not to come close to the anus or the genitals (although the effect of capsaicin there is not as bad as you may expect, in my experience). Wait a couple of minutes, then use the cleaning wipes and paper towels to eliminate the remaining of the pepper juice from the skin. Leave your bottom to roast while you put away everything. Wear gloves throughout the process and wash your hands afterward, for good measure. But remember: anything that touches those buttocks may get capsaicin on it. Capsaicin has a nasty tendency to travel from the butt to your hands, and from there to your eyes.

The results

The bottom will become increasingly hot after five minutes or so. If the treatment is mild (light spanking, a low dose of capsaicin), it will feel like an enhanced afterglow. With a strong treatment (hard spanking, lots of capsaicin), it will be definitely painful. The effects can last as long as 24 hours, peaking around 1–2 hours and then gradually decreasing. The worst (or best) part is the sensitivity to touch (allodynia), with some delightfully humiliating consequences. You can make the bottom feels being spanked just by putting a hand on the buns. Sitting may be extremely uncomfortable or impossible. So it will be wearing pants or underwear, a loosely-fitting skirt is advisable. All of this will probably turn-on your subject, making her excited and horny. You should plan for a sub-space lasting many hours and take advantage of all the wonderful side effects. For example, fucking her doggy-style will add a jolt of searing pain at the end of every thrust. (I have tried to keep all this gender-neutral; of course, a man can also be fucked doggie-style).

Let me emphasize that this is a one-way journey. Once the capsaicin has been applied, it is futile to try to wash it off. If the effects are too strong to endure, have her lay on her stomach and cool her bottom with a bag of ice. Aloe or other soothing lotion may help, but keep in mind that every time you touch those burning buns to apply it, it is going to hurt. Better to stay with her in the scene and enjoy the ride.
