Looking for stories about forced orgasms

Hello,

I hope this is the right forum.

I'm looking for stories about girls that are forced to bring themselves to orgasm, like the girl on the bike in this story: www.xs4all.nl/~wijnands/bdsm/fis/fis8.txt.

I'm also looking for stories of girls that trap themselves inadvertently on fucking machines or other stimulating deviced.

Thank you for links.

as to something specific i'm unable to help, but there are quite possibly stories about such things in the BDSM Library stories section, http://www.bdsmlibrary.com/site/library/list.php
however there are other story websites available if you browse around.

hope this helps :) x
