Fur Affinity Description

The Rattapedes are sexual parasite of unknown origin that alters their hosts' behaviour by controlling their sexual response and eventually altering their bodies too.

Below is the life cycle of the Rattapedes and how they affect their hosts.

Finding their first Host:
- Once a potential host has been located a Rattapede will aim to jump onto the creature’s back to take them by surprise and inject some venom/honey into the their bloodstream.
- Then venom/honey will act quickly performing to role of muscle relaxant to unconverted tissue, and altering the creature’s behaviour via controlling sexual response.
- With the potential host subdued, likely on the ground and also incredibly horny the Rattapede will explore the creature’s body, using it’s sight and smell to locate the creatures genitals.
- When it has located the creature’s genitalia the Rattapede will connect it’s tail to the engorged organ and begin to deposit more venom/honey and eggs inside the new host.

Converting their first Host:
- With the host conscious but unable to move, they are unable to prevent the Rattapede from depositing eggs and venom/honey inside their reproductive organs.
- The venom/honey will act quickly inside the host’s reproductive organs, altering either the womb or scrotal sack to hold gestating Rattapede eggs and altering the testis/ovaries further.
- The ovaries/testis are modified to produce needed nutrients for the Rattapede’s eggs to gestate, however nutrients from both sources are needed to quickly gestate Rattapede eggs fully.
- If the Rattapede Eggs are only getting nutrients from one of either testis or ovaries then the time taken to gestate the full batch of Rattapede Eggs will be doubled.

Rewarding their first Host:
- Once the conversion on the host’s reproductive organs is complete the host’s brain will receive a massive dump of Dopamine and Serotonin as a reward for enduring the pain of conversion.
- Utilising these chemicals the Rattapedes can influence the host’s behaviour by feeding their brains these two chemicals whenever the hosts act in the Rattapede’s interests.
- On the flip side, when a host does something that wouldn’t benefit the Rattapede’s nest in the long run they do not get a dose of these two chemicals, thereby training them in how to behave.
- Hosts will become addicted to Rattapede infestation very quickly and will therefore suffer from extreme withdrawal symptoms should they ever be separated from the parasites.

Finding a Second Host:
- Rattapede hosts will not actively seek to infest more creature unless they are alone in their nest or there are too many Rattapedes and or Rattapede eggs for them to take in and gestate alone.
- Hosts in these situations are incentivised to spread to family and/or close friends with larger dumps of Dopamine and Serotonin when they think about infesting them.
- When a second potential host is located and brought near the situation will play out very like the infestation of the first host, but with the first host acting like they are trying to seduce the next one.
- The first host will actively participate in the conversion of the second host, aiding the Rattapedes or giving a commentary about how the second host will feel better once the pain goes away.

Completing the Rattapede Nest:
- The second host will also be rewarded with Dopamine and Serotonin once they complete their conversion and any subsequent positive thoughts about to the nest will be rewarded in kind.
- Once the second host is converted the reward that is given is given to both hosts simultaneously and is a little stronger than when it was given to just one host.
- The addiction to breeding Rattapedes is reinforced in the first host and the second hosts starts to get addicted as they receive more rewards.
- From now on the Hosts will be drip fed rewards of Dopamine and Serotonin whenever they do anything related to the Rattapedes, keeping them on a constant sexual high.

Rattapede Oviposition:
- When the host is initially converted ten eggs are pumped into their reproductive organs from the infesting Rattapede before the Rattapede itself climbs into them to feed the eggs.
- When the Rattapede climbs into it’s host it digests itself into nutrients for the eggs, but not before spiking the inside of the reproductive organ to mix the host’s blood with more venom/honey.
- The host will happily allow the next and subsequent Rattapedes to lay their five eggs, then climb inside them, as they are rewarded for their obedience with more pleasure chemicals.
- Once the fifth Rattapede has laid all five of it’s eggs and entered the host’s reproductive organs the first half of the gestation process begins in full, this takes about half an hour.

Egg Gestation:
- A single host can gestate eggs in stage one without any other hosts present, but while both the first and second stages don’t require two hosts, they will take twice as long with only one.
- With a second host present the gestation process proceeds normally, in stage one both hosts gestate their eggs for the required time before the second host transferrers their eggs into the first.
- The second stage involves the thirty eggs from the second host being transferred into the first host to merge with the thirty already inside them again gestating them for half an hour.
- While gestating the eggs do not grow much, instead they absorb nutrients to build up a stock of genetic material to use when laying eggs of their own one they have hatched.

Egg Laying:
- After both half hour gestation processes are complete the thirty immature eggs will be ready to be laid from their host, both hosts will clear a suitable place for the eggs to be piled before laying.
- During laying both hosts will be fawning over the immature eggs and likely massaging the swollen part of the first host’s body that holds the eggs to ease them out.
- After the eggs are laid and in a pile they will begin to swell up as they absorb the Rattapede Honey that has leaked out of the hosts during infestation and gestation.
- The eggs will sit like this for about two hours as they swell up to their maximum size and mature fully, during this time the hosts are free to do anything they desire…

Hatching:
- After two hours have elapsed from the last egg being laid, the first egg to be laid will open to reveal a mature Rattapede climbing out, covered and dripping with Honey.
- The eggs have the appearance of giant frogspawn with a terquoise green tint to their core but when they hatch it is revealed that their look is an optical illusion to make the core look smaller.
- The eggs will only hatch if there are creatures nearby and even then only five eggs will hatch for each nearby creature, leaving the rest sitting dormant until more creatures come near.
- Leftover eggs after they have hatched provide a great source of food for hosts to eat between breeding sessions, they are sickly sweet with a salty cum-like aftertaste, just like the honey.

Further Breeding:
- After the eggs have hatched, breeding will resume in exactly the same way that it started, but instead of having to rape the hosts, now they want it more than anything in the world.
- Over the course of a few days all of the fluids in a host’s body will be converted into Rattapede Honey, with anywhere their fluids show changing colour accordingly; eyes, skin, etc…
- After about a week of infestation, the Rattapedes will be able to enter a host’s body through their anus; the host’s internal organs having been mutated around to allow the change.
- A day or so later, Rattapedes will be able to enter a Host though the host’s mouth; the host’s digestive tract having been heavily altered to allow this modification to their body.
- One year after being infested a Host will begin to look slightly emaciated; while retaining some fat in the breasts or buttocks most of the host’s body will look like it had been drained of body fat.

Other information:
- Any offspring that a creature is carrying inside it when it is infested will be converted into a Rattapede over the course of a week depending on how old the offspring is.
- Rattapedes have a genetic memory and any host that dies will have their memories recorded by the Rattapedes, their soul will even live on inside a new Rattapede for however long it wants to live.
- Rattapedes do not degrade over time as long as they have access to water and/or hosts and they can hibernate in a hard cocoon of honey that is made to look like they have turned to stone.
- The Rattapedes are sentient creatures that can choose to forgo their life cycle if they want to and use their practically infinite lifespan to do other things like any other sentient creature.

Guidelines
- Do not use the Rattapedes in situations of Extreme Horror or Gore.
- Do not use the Rattapedes as food for other creatures.
- Do not use the Rattapedes in situation with heavy watersports or scat.
- Rattapedes cannot be mind controlled and are immune to necrotic, psychic and radiant attacks
- Rattapedes are weak to acid, bludgeoning, cold, fire, force, lightning, piercing, poison, slashing, and thunder attacks.
- Rattapedes can attack with piercing, poison, psychic and slashing.
- Rattapedes can inflict charmed, frightened and paralyzed.
- Rattapedes can be magically altered to produce more honey and less eggs but not the other way around.
- Rattapedes don't take genetic information from their hosts and are unable to take on traits of their hosts.
- When a Host dies, it's mind is transferred into a specially grown Rattapede that will then climb out of it's old body.
