Looking for a story?

[bamboo_moon]

It is about a doctor testing the limits of the female orgasm.
She gets volunteers, straps them down, and then uses some kind of machine to fuck them.
In the second chapter she uses herself as a subject.
She gets fucked by the machine, and then her assistant joins in for the experiment.


Anyone know which story this is? I've been looking for it for almost a week and I can't find it.

Please help

Why does she strap them down??

There's a link to something like that in my sigline, and probably better, too.

I've read it, and it is also one of my favorites.
But I'm looking for this particular one for my girlfriend.
