Giantess feet

Giantess feet are know to be both gigantic and nasty.

They come in all sorts of sizes and shapes, even in the same age groups.

Analogous to the rest of their body, giantess feet are 10 times bigger than a normal female foot of their shoe size, when they are in their 20s. Foot growth is constant with each feet gaining about 11 cm each year.

Their feet are know to be especially stinky, the least smelly being able to kill a human in a few direct sniffs.

As they are aware of the power of their stench, giantesses apply a "bridal seal" on their slaves to prevent **** or dismays from their feet, keeping them 24/7 awake and aware.

Not only they smell bad, their feet are also known to produce vile substances that ooze out of their pores.

First we have sweat, the quintessential feet byproduct. Unlike what one could think, giantess sweat is sterile, so it doesn't contain any bacteria due to the nastiness of the concoction.

Its stench comes instead because of the smelly and bad tasting chemicals that form it. That chemicals give it an oily consistency instead of the liquid one of human sweat.

Giantess feet make big amounts of this substance. In just a minute, a one square meter patch of feet skin can produce about a liter of sweat, with the flow tripling in the toe area.

It's important to note that all aggravating factors for sweat, be it GPN or any, apply only for sweat that it is oozed away, not the one that mixes up with other compounds and as such sweat is counted only as a completed product not a prime matter.

Secondly, we have dead skin. As giantess feet are very soft (And beautiful) they have to shed skin regularly to keep themselves like that.

That process starts at the beginning of each terrestrial season, with it having a duration of about one week.

The shedding starts with the appearance of thick callouses over the ball of the foot and the heel, with later ones appearing on the toe pads and along the sole.

At one point of the week, the callouses will be so loosened up that they could be removed entirely with just one pull, which will have ALL the dead skin in one thick film except the one in the toe pads.

If the skin isn't removed manually, it will eventually be soaked in sweat and will form a dense paste that will fall off like a piece of toejam.

Talking about toejam, the last byproduct is by far the vilest of all. It can only be produced in the undersides of the toes, between the ball and the pads, or in between them, as these are the only places with the required oil glands that makes this substance possible.

Mixing up sweat, skin and oils in this regions for extended periods has as a result a gooey yellowish/orangery mass of condensed foot flavour.

However, this process is slow, as 20 years old giantesses can only produce 1 kg of this sludge each day in each foot.

It can be increased a lot though, to the point that the sweat that goes into forming toejam is more than the one that it is expulsed normally and accounts for all sweat modifiers.

All this excesses may be prevented by raising the density of both sweat and toejam, sometimes reaching points where the density is so high it should collapse into a singularity, but they don't somehow.

The "basic" density for sweat is around 1,16 kg/l where for toejam it is 1,53 kg/l. The density can also be lowered, but it is rarely done since it would make the by-products more pleasant.

Nevertheless, both sweat and toejam increases their production way faster than the growth of the foot.

For example, a one squared meter patch of skin in a 40 years old produces 4 liters every minute, 9 liters in a 60 year old, 16 in a 80 year old and so on.

And toejam is no different. The production for a 40 years old is 16 kg a day per area of skin, 81 for 60 years old, 256 for 80 years old and so on.

Like sweat, the production increases by area units not by the total, so the increase is for every patch of skin equal to the total toejam producing area of a foot of a 20 years old.

Dead skin, though, remains fairly consistent throughout the ages, only increasing inside special footwear.

As their feet produce so much materials, giantesses have developed the ability so suppress the volume of byproduct created by increasing their density.

Changing the topic, giantess feet are covered in small receptors very susceptible to male secretions.

The contact of these receptors with male sweat can trigger a sexual response on the giantess, giving them great pleasure.

However, sweat is not the most pleasurable of male secretions. Saliva, for example, is 10 times more delectable than sweat and cum is 1000 times more effective than saliva.

This explains the liking of giantesses to getting their feet rubbed, licked or fucked by a male.

Finally, we have aggravating factors one of which is footwear.

Just by wearing it, due to a particular reaction with the most basic compounds it has (It has to be practically indestructible and has to grow at the same rate as its wearers), can increase the overall sweat the feet produce by a factor of 4.

As giantess feet already sweat profusely, some shoes come with specialized nano tunnels that help to evacuate sweat (Yet not solid compounds).

Dead skin is more complex, as the effects depend on the zone. In the toe area, the increase is the same as for sweat and oils, so toejam is also quadrupled at minimum.

For the rest of skin, it accelerates shedding by half the multiplier of sweat generation.

It's important to emphasize that these are the values for the worst footwear and do not take into account the insulation provided by it.

Some of the best products out there have multipliers with over six zeroes and are only used by the most genetically gifted individuals.

Socks and similar are used, but just for filtering purposes. It is the main way giantesses are able to control and classify for different by-products.

It isn't generally used by mistresses as it inhibits shoes' ability to boost feet but sometimes slaves are **** inside of an specific sweat-filtering stockings so they can be watched while mowing dow the toejam and dead skin that accumulates inside.

The next modifying factor is temperature.

Giantesses can withstand all types of temperatures even the most ****. There's literally no limit to the heat that can be applied to their soles.

Every Celsius degree over 0 in the environment will increase sweating by x1.03 and toejam by x1.02.

As their feet produce a lot of heat, if trapped inside closed shoes they can reach temperatures around 40 Celsius.

However, the modifier appliers to a temperature equal or lower that the female's age.

Finally, we have cum. That's it, cum.

Whenever a man ejaculates over a giantess' sole or toes, part of the sperm's genes enters the body.

Later it fuses with the female's feet-related genes, increasing their foulness.

Every million sperm cells that reach the foot skin will increase both sweat and toejam of every single patch of sweating skin by a multiplying 0.0001%.

Nevertheless, most of the sperm doesn't reach its target due to the amount of sweat that washes it.

To counter that, giantesses make their husbands cum inside toejam globs. There, the cum slides slowly towards the skin and it can really increase the efficiency of the process.
