Authors notes: There is not a lot of proper sex in this one. It's more descriptive about how the dwarves' mate, their anatomy, and the rituals they have around sex. I tried to make something you might actually believe would appear in J.R.R. Tolkien's The Silmarillion. I hope to write more "doing the nasty" stories in the future about these dwarves. I don't care if you use this to make your own stories using this. In fact, I encourage it if you found it hot. Hope you enjoy.

Regarding Dwarves and Their Mating Patterns:

Dwarves were created early in the years of the trees by the melodies of the almighty Eru Ilúvatar and the great Valar Aulë. Very long ago, before recorded history of the dwarves, they did not reside within the mountains. They lived much like the elves only in mountainous regions which they have always been fond of. They had neither the skill nor the tools to delve deep within the earth at this time. Dwarves were very focused creatures, so they did not often mate. Instead their endeavors with stone and gems kept their minds busy. Most years there are little to no dwarven children at all. They are content to mine and build as they see fit without hearing the call of their loins.

Aulë blessed dwarves with long life spans but knew that if he did not control their mating habits their numbers would disturb nature. Only but once every five years do the female dwarves get bred by the males. On these years all the pent-up sexual tension of the last four celibate years needs to get released. This is when the male dwarves go into rut and have an insatiable need to breed and relieve their dwarven lust. During these years they are very rarely seen outside of their halls. Despite the males need to release their sexual tension every fifth winter, the female dwarves do not go into heat in the same way a human female would. Females desire to reproduce, but do not have a lustful drive like the males. This is the way of dwarves. The males would chase the females only once every five winters and the females would have very little desire at all to mate. They were divinely created this way to compensate for their long life spans.

All was good in the first years of the dwarves. They grew and learned about their lands and the mountains. When the time to mate came the males would pursue the females. There was ample room and space for them to mate and not disturb the natural order of things. The females would be bred by the same male many times and then go into solitude to care for the growing fetus. The male would then search for his next mate. In a number of months, the year would be over. The females would come out of hiding with their children, return to the clan of dwarves they belonged to, and the clan would raise the child together. The females would be in charge of knowing which male was the father and this is how the dwarves kept records of their lineage.

Thus, Aulë made dwarves. All dwarves are shorter than men or elves. They reach around 5 feet tall and are very stout. In old days it was joked by the tall men that dwarves were made of half fat, a quarter muscle, and the rest was hair. And so it was for both males and females. Most female dwarves look very similar to males for they have beards and do not have distinguishing clothing. Dwarves are born with beards and they do not shave. Their hair grows down past their shoulders and most of their bodies is matted with thick and bushy tufts of hair. Some dwarves merely have as much body hair as a moderately hairy man would have. Most are very hairy throughout their body, and in the most extreme cases the dwarf is so hairy that their skin can hardly be been beneath their hair. These extreme cases only occur in males and are more commonly seen in the halls of Nogrod. This trait is seen as a distinctly sexual to most dwarves. The differences in the dwarven genitals is described in further paragraphs.

The defining traits of dwarves (being muscle, fat, and hair) are held in high regard and are seen as attractive to both males and female. Noble dwarves are usually fatter due to their share of food being larger. The heavier the dwarf the more noble he likely is. There are some dwarves on record as being so large around that they lose the ability to walk. These dwarves are taken care of very well once the breeding season commences. Because of their social status and nobility, nobility rarely will touch themselves during mating season. Young dwarven men are tasked (honorably so) with pleasuring these nobility in every way they can. It is one of the greatest honors of a young dwarf to be assigned to the lord of the hall himself. Durin the Deathless, father of the dwarves, and King of Kazad-dûm took so many young dwarves to bed in this way that every dwarf can trace his ancestry back to one of Durins helpers. It is a great pride to all dwarves.

Muscles are also highly regarded within the dwarven halls. It's common for the lower-class dwarves to be very muscular due to their hard-working lives. Tattoos also are more adorned by less noble member of the halls though they can be seen on dwarves of all nobility. Thráin the First had skin that was nearly blackened with these markings. Muscles signified good breeding quality. The penises of the muscular dwarves are usually longer, and they produced more and higher quality semen. There is a respect for a male that could maintain a high amount of muscles and these males are naturally sought out during the times of breeding.

Males are generally larger than the females, but they are very hard to tell apart aside from their genitals. Outsiders such as men and elves rarely see the females and often times mistake them for males when they do. The number of males outnumbers females two to one. Because of these reasons, male to male mating rituals were often undertook even before they delved under the mountains. There is little difference between male to female sex and male to male sex except that impregnating females take precedent. If a female is unavailable when the males are in rut, they will copulate with each other either orally or anally or by using their hands. Within the mountain halls there is great pride males have in serving another dwarf when his reason is clouded with lust. This forges a brotherly bond that plays a large role in the dwarven communities and friendships. It is very uncommon due to the nature of dwarves and their general lack of interest in mating and forming romantic relationships, but there are recorded instances of two males becoming life mates. This phenomenon is echoed in lesser amounts by males having common mating friends that they will return to each time they feel the need to breed.

Dwarven genitals are very similar to those of humans with a few important differences. The vagina is different in many ways, but one of the most important features is the length of the vaginal and birth canals. Because of their diminutive stature both canals are much shorter than a humans. This difference is also probably due to dwarven babies being larger than humans relative to their parents. The gestation period for dwarves is around 12 to 13 months despite the smaller size of the species. The vagina is designed to minimize difficulty and danger to the mother during birth. The functionality of the shortened vagina does have a drawback. If a male were to breed a female during the entire gestation period, the intruding penis could harm the growing child. This was not a problem before the dwarves created their mountain halls due to females being able to leave the presence of the males. Once the halls were founded gestation chambers, or the Thamb Galas, were created to protect the babies.

While a female does not go into heat, they do find happiness in being bred. It is usually very emotionally fulfilling to be bred especially by a husband or a member of the nobility. Birthing a child was seen as an important part of many, but not all, dwarven women's lives. Some females had no desire to mate at all. They are called Velukrumm and care for the women during pregnancy.

The male dwarven anatomy is different form that of men in much the same way as the female anatomy. A dwarven penis is roughly the same size as a man's penis despite the dwarves being smaller in stature. This gives the appearance that their penises are larger than they are. Because of this it is rumored among human females that dwarves make excellent lovers. (There are recorded cases of half dwarves, but they are very few in number.) The shaft of dwarfs is shorter than of men, but they are fatter as well. This is to make up for the shallower vaginas of the females. These differences are not drastic and some dwarven penises have a very similar length and girth to the penises of men. Dwarven penises are slightly darker in color than human penises.

There are two distinguishing physical traits of the dwarven penis when compared to humans. The first and most obvious are the testicles. When a dwarf ejaculates, they must make sure the egg is fertilized due to the rarity of their breeding. Because of this the dwarven testicles are much larger than that of a humans. The scrotum can be around two to three times larger than a human penis. It is not uncommon for a dwarven teste to be as large as the egg of a duck. They are the most valuable jewels in the dwarven halls. Their semen contains much more sperm than a human ejaculation. Dwarven semen is also very viscous compared to humans. This is thought to prevent it leaking out of the vagina once a female has been bred. The consistency is rather like a thick and very sticky honey.

Despite the viscosity of the semen a dwarven ejaculation is quite impressive. Everything about their anatomy is designed to maximize breeding chances. Due to the rarity of the breeding and the need to make sure the women are pregnant; the male body produces an astonishing amount of semen when the male is in rut. Indeed, the males have a special sac within their pelvises that holds a reservoir of the precious life giving fluid. Their body will produce as much as possible and if the male doesn't ejaculate it can be very uncomfortable and in extreme cases cause health problems (this is very rare due to masturbation being common during the mating year.)

Even if the male ejaculates often the amount of fluid expelled from their bodies is significantly larger than humans. The amount of fluid that is produces is around 5 to 7 times more than the average human if attended to. However, if the male does not ejaculate for a significant period of time the amount of semen can be shocking. It is a pride among dwarves to produce as much semen as possible. In the crazed Kronul Nogazen Khaz (Hall of brotherly love) there are held competitions to see who can ejaculate the most voluminously. A skilled dwarf can fill a cup or even bowl with the proper training from only one orgasm. Lastly the semen differs slightly in appearance and odor. While the ejaculation of men is very white and sometimes clear, the dwarven fluid has hints of silver color and a metallic quality to it. It smells, like the dwarven musk, of the earth itself.

Dwarves have a very strong musk and earthy smell. It gets stronger around their genitals and is amplified when the males are in rut. Like all traits of the dwarves, it is deeply connected to the earth and the mountains they live in.

The dwarven love of precious metals and jewels plays a role in many dwarven sexual activities. Piercings around the genitals, nipples, and are common and decadent jewelry is considered a symbol of masculinity. The mountain lords have special adornments for the breeding seasons, and they are considered highly sexual.

In the days of old, before the beginning of the first age when the world was young, the dwarves lived above the mountains and fed off its roots. This was their natural breeding ground. However, as the dwarves began to delve into the depths of Arda there needed to be changes in their habits. The smaller spaces meant the females could be bred all year long and that the females had no peaceful gestation period. This caused many infant mortalities and forced the population to dwindle. Because of this reason there was a massive tradition among the dwarves that occurred every five years. The yearlong celebration is called the Krogazen. (Note that Krogazen is also an abbreviated term for a Kronul Nogazen Khaz. Krogazen is both the breeding year and a male sex chamber.)

The beginning of Krogazen is not marked on any calendar in Middle Earth. The start is known to dwarves for two reasons. The first is that the male urges start to develop. Slowly at first but quickly become almost uncontrollable. The second reason is much more subtle. It is said that the halls and mines of the mountain fill with a thick scent of the male pheromones. For humans and elves it would simply smell more earthy and musky, but to the dwarves it means that they will soon be called away from their work to enter the Kronul Nogazen Khaz, as well as the breeding chambers, and release their sexual desires.

There are problems that dwarves had to solve. The dwarves that were married, although few among them, would not like it if another dwarf bred their wife. Due to this reason, the married dwarves would start their breeding about a week early to ensure the best chances of impregnating her. These women would be the first to travel to the birthing place. The birthing place is hidden from all eyes except for those of female dwarves. There is an ancient magic that binds it so. After the marital breeding, a lottery is used to pick the males who will breed the remaining females that wish to be bred. If a male hasn't bred a female in multiple drawings, he may be allowed to do so by bypassing the lottery.

The breeding process is much more drawn out than what humans are used to. When a male is randomly assigned to a female they will go to a private room and be left there for a week. They are brought food and water but otherwise left alone. Once left alone little time is wasted. Both male and female strip and the female is mounted. Once the male mounts there is almost no point within the week where he is not inside the female other than to rest, eat, and let his bodies make more semen and sperm.

The first insertion can be difficult for the male especially if his genitalia is wider than average. Although the vaginal canal is shorter than humans, it is still a smaller opening. The penis can be extremely tight within the vagina. Fully inserting the penis into the vagina often causes the first ejaculation for the male, but unlike humans, this is very common and is only the very beginning of the breeding process. Once the male has fully entered the female they will formally begin mating. The male continues to thrust into the female for hours at a time ejaculating several times before taking a break.. At this time the male is consistently in a sex crazed state and will not take his penis out of the vagina until he leaves this state.

The thicker penis, the thinner vaginal canal, and the viscosity of the semen ensures that all the males fluids are kept within the vagina and womb. The emissions will build up and be used to nurture the growing dwarf child during the early pregnancy. Throughout the weeks the female's belly will begin to expand due to the volume of semen that is inside her. The dwarves brag of the number ejaculations that they manage to have in this week. The dwarves themselves might tell you that a good breeding week will contain upwards of one hundred ejaculations, but this is most likely apocryphal. It is estimated that the actual number of emissions is around forty to fifty. This is more than enough to ensure insemination.

After they are bred the females will be escorted to the secret chambers and the males are given another week to rest. However, the men are far from being satisfied. Only six weeks has passed within the breading year for even the latest of breeding males. Because all the females are gone an ancient and beloved tradition among the dwarves was born. The Kronul Nogazen Khaz (shortened to Krogazen) is a sacred hall within the mines of the dwarves. It is were the males indulge in their rut passions together.

The importance of the Hall of Brotherly Love cannot be understated. For the dwarves this is one of the most precious bonding experiences they have with each other. This ritual binds the males together like nothing except the heat of battle can. For the dwarves it serves as a kind of antithesis for the heat of battle. In battle the men would be united in presence of death, but in Krogazen they are united in the presence of life. In the year of breeding a male will spend the majority of his time in this chamber having sex and masturbating with other male dwarves. There are many aspects to Krogazen and writing of all of them would be nearly impossible. These will be general themes and practices of the acts within Krogazen but will by no means be an exhaustive list.

A very important part of Krogazen is the size of the chamber a dwarf is currently in. The main Krogazen ,which is also called Haran Delâs, is the central orgy chamber. The Haran Delâs is a large chamber with a low ceiling (approximately 60x90x6 meters in size) very deep within the heart of the mines. These chambers are a testament to the ingenuity of their kind. The main hall must be built in such a way that allows it to be cleaned. Because of this they must be built near an underground river. The buildup of seminal fluid at the floor of the cavern gets so high it can cover the foot of a dwarf. Once the semen has built up enough, the river is directed to flow through the chamber to wash it away. After the floor has been cleaned, the males continue their bonding rituals. Many of them do not stop for the water. The chamber is not empty for the entirety of the year. In fact, the hall is often so packed with dwarves that it would not be possible to extend one's arms without making contact with at least 2 other males.

This room is very beautiful as it is sacred to dwarves. Each is different and symbolizes the values and history of the dwarves. Some are constructed very precisely and intricately. Others are built to look like the mountain was untouched. All of them are adorned with phallic art. Pillars, sculptures and painting all depicting the rituals of their fathers and grandfathers. Man with man in one of the most ancient traditions of the proud people. There are dozens of traditions within the Haran Delâs. A popular one is a competition seeing which man can ejaculate the most semen. Another is the initiation of the dwarves joining their first Krogazen.

There are many smaller specialized rooms as well. These rooms vary in size and are dedicated to different ways that the dwarves like to have sex. There are a great many of these because unlike the Krogazen they do not solely function as sex chambers and can easily be returned to the way they were before the breeding year. Lastly there are individual rooms that are used extensively for small groups of dwarves (usually 2 to 5) to more intimately bond. In fact, for many males, these rooms hold the closest thing to a partnership that they will choose to partake in. If two males consistently choose to inhabit the same bonding chamber each Krogazen, they become very close and intimately familiar with each other.

When a male is done having sex for the day he will return to his work and come back to the sex halls when his loins call for him once again. This cycle repeats for the whole year until the dwarves leave their rut and the females return. After the closing ceremonies they will return to their normal lives and raise their children. Much less frequently some males will revisit their smaller halls and bond for a day, but never in the main hall and never to the same extent. In four years, they will return the great sex hall and start again. This is the ancient tradition of the dwarves.
