Nipple Development Levels

Development Levels​

Below, we have organized the levels of nipple development. You can use this article as a roadmap for your nipple development journey. The starting point for men is usually between levels 1 and 4, while for women it is usually between levels 5 and 13.

::: warning This article is a complete translation from a Japanese blog, so its credibility is questionable. In the "Born Like a Summer Flower" community, no one has been known to reach level 20 or higher. :::

The First Realm of Nipple Sensitivity (Ordinary Person)​

  1. Feels nothing even when touched (like any other skin).
  2. Can clearly tell when it's being touched.
  3. Feels a slight itching sensation when touched.
  4. Feels an itching sensation when touched.
  5. Feels a slight pleasant sensation when touched.
  6. Feels a hazy, unexplainable sensation when touched.
  7. The hazy sensation gets stronger, and the mind starts to feel dazed when touched.
  8. Feels a very slight sense of pleasure from the nipple when touched.
  9. The nipple starts to feel comfortable when touched.
  10. The mind becomes hazy, and the nipple feels comfortable when touched.

The Second Realm of Nipple Sensitivity (People who can achieve a nipple climax)​

  1. You clearly realize that this is a form of pleasure. Your nipple feels very comfortable.
  2. You will gradually get into an aroused state (albeit very slowly). If you're lucky and the conditions are perfect, you might achieve a very mild climax after a certain amount of continuous touching.
  3. You will slowly but surely get into an aroused state. After a certain amount of continuous touching, you can reach a climax with a 30% to 50% probability, depending on the day's conditions.
  4. You will switch to an aroused state (the accumulation of eroticism speeds up significantly). After a certain amount of continuous touching, you have a 50% to 80% chance of reaching a climax and can occasionally achieve 2 to 3 climaxes.
  5. You will indeed get very aroused, and if you continue, there is a 98% chance you will have a mild climax. If you continue even further, there's about a 50% chance you can have an even deeper climax.
  6. You feel a slight sense of comfort when your chest is touched. Touching your nipples will definitely get you aroused. 100% of the time, you will climax if you continue touching, and you will distinctly experience a continuous climax.
  7. [Breast Enlargement] For men, at this stage, the chest is soft enough to be kneaded. You will feel a slight sense of pleasure from touching your chest even without touching your nipples. The nipples themselves are the same as at level 16, but the pleasure will be even stronger.
  8. You will feel a sensation when your chest is touched, and touching your nipples will envelop you in intense pleasure, and you can climax many times.
  9. Your nipples will become strongly erect! Touching your nipples will quickly get you into an aroused state. The time it takes to climax will be shorter, and the pleasure will be more intense.
  10. [Breast Enlargement] For men, you will feel your chest vibrate when you walk (meaning the entire chest is sensitive enough to feel a tremor). When you touch your nipples, you will feel pleasure as if the inside of your chest is being caressed. You can climax in 15 minutes. Continuous climaxing is not a problem at all, and it's very blissful.

The Third Realm of Nipple Sensitivity (Lewd Person)​

  1. The nipples have become somewhat hypertrophied. From this stage on, you can sometimes see erect nipples through a T-shirt. The erection of the nipples is very noticeable, and their size, height, and hardness are significantly enhanced.

    If you continuously stimulate your nipples at this stage, you may reach an "intense climax" where your mind is filled with a starlit galaxy.

  2. The nipples continue to get larger. The size of the nipples in a non-erect state hasn't changed significantly since level 18, but when erect, they protrude quite powerfully (and the chest thickness is considerable). In nipple masturbation, you feel extremely satisfied with the pleasure, and your mouth half-opens in a broken smile.

    At this stage, it's impossible to stop nipple masturbation. If you try to stop, you'll remember the pleasure and continue. This is the same for women.

  3. [Breast Enlargement] For men, the chest is now an AAA cup (and for women, the breasts have increased by at least one cup size). The breasts shake intensely when you move. In nipple masturbation, your lower back and back will be filled with intense pleasure, and your body will move against your will. Depending on the day's conditions, you can feel such immense pleasure that you temporarily lose yourself.

  4. Even in daily life, the nipples may have some erotic response (depending on individual differences and how you experience eroticism). Also, when you watch videos of nipples being tormented, your chest will involuntarily feel a sensation. The amount of pleasure is similar to level 23, but the time it takes to climax becomes shorter.

    (Note: If a man develops his nipples very quickly, the sensitivity may become so high that he needs to wear a bra or nipple patches.)

  5. The areola around the nipple can also feel a significant amount of pleasure. For men, you may be able to rub your breasts, and depending on the level of training, you may even be able to achieve a mild climax by simply continuously looking at your nipples.

    After this, if you continue touching your nipples, the sensation will be so good that there is nothing but bliss. In the deepest climax, your vision and consciousness may become fragmented (like a fleeting memory) or you may experience synesthesia (seeing bright colors, feeling a sweet taste, etc.).

  6. [Breast Enlargement] Even a vibrating toy can bring pleasure, and stimulating certain areas may cause a climax (this varies by individual). Of course, you can also get pleasure from electro-shock stimulation and other devices that use electricity.

    Even with a light touch to the nipples, your body will feel a gentle breeze. If you continue to touch the nipples, you will naturally achieve a deep climax, and your body will involuntarily sway.

  7. Even at this level, nipple sensitivity can continue to increase. After reaching 2 to 3 climaxes, you may remain immersed in a deep climax for a period of time. The climax causes a full-body tremble, your eyes close, and you make gasping sounds. Sometimes, you may experience a terrifying climax that is completely out of your control.

  8. [Breast Enlargement] For men, the chest is about an AA cup, and the nipples are quite large when erect. The pleasure increase rate hasn't changed significantly since level 20, but the ease and depth of climaxing are much stronger than before. Also, the response of other erogenous zones on your body becomes noticeable (i.e., you feel pleasure when you touch these areas of skin). When you touch your nipples, other parts of your body, such as your lower abdomen, lower back, back, anus, wrists, and toes, also feel pleasure.

  9. From this level on, if you continue to climax during nipple masturbation, your entire body can be developed into an erogenous zone. If your body accumulates deep pleasure, your nipples cannot be consciously touched (it may even be impossible to be conscious). No matter which part of your body you touch, it will feel very good, and climaxes will continue until you are physically exhausted.

  10. [Breast Enlargement] If you concentrate and continuously imagine your nipples being played with, you can achieve a mild climax even without touching them at all (though this climax is not very strong).

    During nipple masturbation, you will almost certainly gasp. When the pleasure starts to decrease, you can immediately return to a state of climax. If you wish, you can have over 10 climaxes. When you feel immeasurable pleasure, you can clearly see the "universe," "a world of fleeting memories," "a beautiful, fantastical night world," "a pure white, warm world," etc. In an optimal state, you may lose consciousness for a period of time.

The Fourth Realm of Nipple Sensitivity (The Fuzzball)​

  1. The diameter of the nipples has increased significantly. When erect, their elasticity and size are extremely enhanced.

    The brain begins to love the stimulation of the nipples, and if it doesn't get it, it becomes unhappy and can't resist continuing nipple masturbation. In other words, the pleasure has started to override your rationality. Your tolerance for pleasure has significantly weakened. As a result, the endogenous pleasure during nipple masturbation will strongly defeat your rationality, and you will climax without hesitation.

  2. The erogenous zones on your entire body are strongly developed, possibly because the development of pleasure nerves in your brain can affect various areas, not just the nipples. Specifically, the eroticism in the back, lower back, and lower abdomen is especially developed. The eroticism of the skin has also increased. Holding a towel will make the pleasure during nipple masturbation more intense. In some cases, a climax can be achieved just by caressing your skin. Not only that, but the need to be held during a climax becomes strong. If you hold something after a deep climax, you can stay in an aroused state for a long time until you fall asleep.

  3. [Breast Enlargement] In a relaxed state (where the parasympathetic nervous system is dominant), your body becomes soft, and you can feel a subtle pleasure circulating in your back and lower back (even when you are doing nothing). This is evidence that your body's ability to perceive sexuality has been greatly enhanced.

    During nipple masturbation, it's very likely that you will let out uncontrollable gasps. Since level 30, the pleasure from the nipples hasn't seemed to increase much. However, the nipples are now connected to the eroticism of the entire body, and every part of your body is enveloped in pleasure.

  4. From this level on, even if you stop touching your nipples, your level will not decrease. (However, if you perform some special desensitization treatments, your nipples may become a little less sensitive.)

    On the other hand, the sensitivity of your nipples will steadily increase day by day. If you don't touch your nipples for 5 to 7 days, your sexual desire for them will accumulate, and you will be reminded every day to engage in nipple masturbation.

    Of course, you can release this sexual desire with a thorough nipple climax. However, if you do so, the eroticism of your nipples will continue to develop. This means that unless you use special methods, it is impossible for you to return to your original state!

    (An exception is that eroticism will naturally decrease with age, but this is a very slow process.)

    (Also, if you strongly suppress your sexual desire, it might be possible to return to your original state.)

  5. If you do not engage in nipple masturbation regularly, you may enter a state of being "in heat" (meaning you feel extremely aroused no matter what you do).

    This arousal does not refer to a man's original sexual desire but specifically to the sexual desire for nipple masturbation. This force is so powerful that it's basically impossible to control yourself. If you take advantage of this by accumulating enough sexual desire and then engage in nipple masturbation, it will bring a lot of extra pleasure. It will be... continuous orgasms that make you cry with happiness!

    (This means that if you accumulate sexual desire for nipple masturbation for a while, the pleasure during the session will also increase significantly.)

  6. Nipple eroticism has developed further. During masturbation, the pleasure from the nipples increases rapidly, and even with a very light touch, you will climax quickly.

    (Even if you don't make a sound, a gasping sound will echo in your mind.)

    During the first climax, you will feel very intense pleasure. During the second and third climaxes, you will be submerged in a pleasure that makes you want to cry, and you will get immense satisfaction from the climax. For men, a large amount of pre-cum will be secreted, and for women, a large amount of female ejaculate.

    When the pleasure from stimulation exceeds a certain threshold, you can continue the climax by swaying your back without touching your nipples.

  7. [Breast Enlargement] For men, the breasts are now quite prominent (about AA to A cup size, which is similar to the size of trans women who have taken hormone drugs).

    However, since most people won't easily understand what's happening, they will simply think you've gained a little weight (in an androgynous way). But if you deliberately stick out your waist or arch your back while puffing out your chest, you will likely give yourself away.

    (At this level, your body might attract attention in a public bath because your chest is so soft.)

    (For women, the breasts will become especially large. They will be very full and look very erotic.)

    By the way, perhaps because the pleasure nerves of the nipples have taken root deeply, just a slight rub will generate pleasure (indirect stimulation also produces a strong reaction).

  8. You will strongly resonate with the female orgasm pattern. When a woman is aroused, pleasure continuously converges on her, and she becomes immersed in a state of "wanting to get even more aroused."

    Specifically, you can observe in nipple masturbation videos that a woman's nipple eroticism can connect with many other aspects. For example, even without a hypnotist's guidance, you can easily enter a state of self-hypnosis. In a climax achieved through hypnosis, you will be enveloped in a warm pleasure. It is a state of ecstasy.

  9. During nipple masturbation, the reproducibility of a state of extreme pleasure is greatly enhanced. (Of course, this level of pleasure still requires some preparation.)

    However, given that the pleasure from your entire body has been strongly developed, when you reach such a deep climax, your state will likely be... miserable.

    To be more specific, gasps will leak out involuntarily, your entire body will tremble continuously, and it will be difficult for you to escape this pleasure because it is so intense.

    When the erogenous zones of your entire body awaken a state of extreme pleasure, this pleasure may remain in your memory for a lifetime. (This is an almost irresistible memory because intense pleasure is easily remembered.)

  10. (If you don't masturbate regularly, you will be unable to bear it. This is probably a form of dependency.)

    During nipple masturbation, you will be satisfied with immense pleasure from the very beginning. When you are aroused, you will always reach a state of unparalleled bliss. In your mind, pleasure may be like a sparkling pink ocean.

    From this point on, you can live a perfect life filled with nipple masturbation.

Conclusion​

If you continue with nipple development, your nipple sensitivity will grow as described above. Once you reach level 12, a nipple climax is no longer a dream. Let's do our best to develop our nipples!

If you follow the magnetic patch development method diligently, your nipple level can increase by one level every 10 to 40 days. However, once you reach level 15, you can consider ending this type of development. The reasons are as follows:

  • At level 15, you can continue to level up through nipple masturbation.
  • If you level up too quickly, your dependency on pleasure will increase, and your breasts will enlarge faster, making the risks more significant.
  • Without the magnetic patches, you can enjoy nipple masturbation whenever you want.

Of course, if you wish to become a "fuzzball," you can continue to develop at the original pace.
