Plushophilia is a fetish involving the veneration of stuffed animals.
To understand this fetish, all you have to do is remember back to your childhood days when your bedroom was filled with different teddy bears and other assorted stuffed creatures. When we were very young, the textured softness of plushies made us feel good and secure. Often, children will create a friendship relationship with their furry friends, having conversations with them and carrying them wherever they went.
As we grow, we begin to socialise, trading the soft creatures of our childhood for the vocal friendships of other humans. There are those, however, who don't cross the bridge between fantasy and reality. There are those among us who would rather create a controlled environment with their beloved plushies than risk a relationship with humans. The true plushophile is usually a guy and his 'bent' is the plushie itself. For purposes of sexuality, the stuffie is modified so the plushophile can have sexual relations with it.
These guys take their plushies everywhere. They modify the plushie, so they can have sex with them or pee on them or 'scat' them or cum on them. They go to the movies and restaurants, etc. One guy went so far as to leave "Lord of the Rings" because he thought his plushie would be upset. The involvement is total and intensive.
There are plenty of informational sites on the Internet. You can find all the definitions, learn the shorthand code for the various sub categories of plushies. There are many sites devoted to cleaning techniques, along with methods of modification to make the plushie more amenable to sexual relations. There is an entire language for those into this fetish.
It would be difficult, at best, for webmasters to create this kind of site, without being an active participant in this type of fetish. For Internet money making, let me address the type of plushophile who would be targeted by those wanting to market this type of site. There are good reasons for webmasters to look at this fetish, for marketing purposes. It's what I call a 'soft' fetish. The content is very simple to shoot, as long as the photographer focuses on the plushier and not on the model and the central point. I've seen both straight and gay plushier sites, where the plushier is the center of attention.
Before I continue, this is fetish is NOT about pedophilia. The people who are into this are not child molesters nor are they children themselves. These are fully grown adults who love their plushies and want to see them be the object of sexual adoration. This fetish is also NOT about bestiality. While it has been theorised the people into plushies would rather have sex with animals, but are afraid to, there has never been any substantive proof that this is the case. Any plushophiles I've ever interacted with have always maintained their stance that bestiality is not on their agenda.
The photographer who shoots the content for plushies will have models that are good looking, in the 18-30 year old range. It is not necessary to dress the model in pig tails with a lollipop. We are not dealing with 'lolita' type content. While the model should be attractive, she is not the focal point. It's the plushie which is on stage here. For the shoot, it's very important to have plushies that are soft and furry. Big teddy bears and sizable animals with very soft fur are desirable. Care should be taken when buying these animals, making sure they aren't too cute or too ugly. There is a certain look and feel which makes a particular creature stand out. The plushophile will certainly judge the site by the type of plushie content presented. There are certain brands which are more attractive to a plushophile than another, usually because of the way the animal looks, the size of the animal; and, most importantly, the feel.
Modifying the plushie so that a strap on dildo can be attached is a huge turn on for those would buy memberships to these sites. Having the model caress and adore the plushie is key to the photography needed. With video, the model needs to treat the plushie like an intimate lover, a best friend, a boy friend. She would hold and talk to the plushie just like she would talk to her human boyfriend. The conversation would be loving and sexual and flirtatious. This type of content is not difficult to shoot, as long as the photographer and the models treat the plushie like a human being. Instead of a guy performing oral sex on her, the plushie would have the honour. Instead of a guy having sex with her, the plushie would have a strap on and would be assuming the positions necessary to portray hardcore sex.
The model teases the plushie with her stripping. She doesn't have to be wearing lingerie or Frederick's of Hollywood type outfits. She could be dressed in a pair of jeans, a cute white top, white socks and sneakers, with lacy underwear. Her entire strip would be directed toward the plushie, while she is talking to it.
One scene that comes to mind involves college aged cheerleaders. Perhaps the two young women share a dorm. On their beds are many plushies. There is one, however, which stands out and is prominent. It could be a gigantic frog or teddy bear. Feet and hands are beneficial, because they can be placed on the cheerleader's breast or pussy. Size, in this case, does matter, because the bigger the plushie, the more it believable and realistic it is. Both girls are into plushies and each other, although the main focus would be them teasing the plushie. Showering it with kisses and hugs, placing its' paws on their bodies, having a strap on dildo attached to the plushie as it plunges deeply inside her wet and waiting honey pot. It's a scene that would do very well on a pay site.
The marketing text would be geared toward the plushie, also. Having the cheerleader tease the plushie by telling it how wonderful she thinks he is in bed, how much pleasure she gets from him, treating him like a real man would turn on the surfers who are into this scene.
Bandwidth usage would be minimal, since the target market is not huge. Creating free sites and promoting a sponsor site is one way to earn money. Galleries also will work. If your favourite TGP doesn't have a plushie category, you can ask for one or just place it under 'Fetish'. Traffic will not come in huge numbers; but, conversions should be consistent.
There is ready made content out there and my suggestion would be to create a premium AVS, with several feeder sites and galleries for traffic flow.
