That's really fucking weird, but ultimately harmless except to the furniture and pants.
But I won't judge. I recently told a friend about my childhood desire to wear a banana costume, which she said was a form of penis envy. I also had a childhood fascination with womens tights which lingers to this day in the fact that I prefer patterned tights to stockings or pantyhose.
In response to Tellurian,
No, the sister site Glued to her Chair featuring "Sitting Pretty" is only farce/entertainment in so much that a company does not actually cater to this yet (although some videos are available). The particular page you reference is just more of a joke than other parts.
In particular, the main site is usually serious, but you gotta look at the lighter side too sometimes.
Yep, it's a very serious fetish. Commercial material for it is small at the moment, but it appears the Japenese have explored the fetish more thoroughly as more stuff is available there.
Also, Orthogonality, please. I agree with most stuckers, gluing should only be consentual. We deplore the act on Bob if it was true.
So yea, I know most of you aren't stuckers, but I don't mind people enjoying the site even if it is just for getting weirded out. I'll admit it is maybe slightly odd, but most fetishes are (like Fenriq, chastity belt fetish could have your same argument). "A fetish finds you," as the saying goes. But I'm sure a small percentage of people pointed at my site will find a wonderful haven as others already have. Have fun! :)
