I like all your ideas but this one has to be my favourite, especially if it was a dominant female doing the "procedure"

Thank you.

I tend to imagine a dominant female doing whatever it is in these, or at least running things if she's not doing something directly. I know there can be variations, so I don't always specify some things such as "sadistic nurse" or "mad scientist" or such.

Come to think of it, I did that one too. Twice.

Ah, nice. Though your design seems to be made to be rather, well, nice about it. Quite understandable, from a practical point of view. So perhaps it'sa Good Idea for you?

For this Bad Idea, I want to see a pair of needles and see the subject/veictim worried about them as they approach sensitive targets... and show that it's going to be nasty. BUt "going to be" rather than "is being."

Thanks for pointing those images out.

I find there's just something amusing about taking these things and making them entirely too innocuous. Warped sense of humor, I guess? To bastardize the Sniper's motto, "Be polite. Be efficient. Have a plan to fix everyone you meet." My equipment is based on roughly a similar philosophy :D

And the.. er.. celebration of the banality of evil, as it were?

I do wonder what other interesting (or not interesting enough?) toys you might have come up with. Or will.

Banality of evil?

I'm just not sure where we're getting the 'evil' part.

My favorite toy to date is the e-stim vibrating bullet. I could perhaps make money selling those to real people over the internets.

Well, that is just what popped into my head just then. Since it seems your volunteers are just that, no real evil as such. Unless they are "volunteers" that is.

And yes, very probably.

Most of them are genuinely volunteers. Some of them are "volunteered" by the dominant partner in the relationship, however, and we have no good way of vetting whether this is the case.

Another idea for this one. Anyone familiar with Neutersol or any of the other immunocontraceptives proposed? At least one concept involves injecting something that causes inflammation (think about that a second...) into the testes, provoking the immune system cells to slip in and have a look around. And since puberty happens well after the immune system is established, the immune system is justifiably freaked out by sperm cells and makes antibodies to attack them.

I think this is more in keeping with the direction you wanted to go on this.

An immune response would have to be 'provoked' since gamete-producing organs are normally out of the apparent view of the immune system to the point that they can be transplanted without worrying about (most of?) the usual rejection issues.

Normally I am aiming more for the pain than the elimination of reproductive ability, though that is an ultimate pain and worry which adds tension. The first thought I had was this would not be all that much for pain but then I re-read and took better note of your note regarding inflamation. There would be an initial feeling from that, and I would assume the immune reaction to be painful for perhaps days. This could be very nasty indeed. It might even be too much. Yes, I just wrote that.

That's... about accurate. And it was actually used to non-surgically vasectomize cats at one point. Very unreliably, at that.

Remember, inflammation recruits lymphocytes to the effected area, and they can squeeze through capillaries and wander loose in tissues. That's the point of inflammation.

what's a hurtzlikehell ven-......Oh...damn!!! Poor bull, as i always say. and if that hurts now, how much pain would he be in if she forces him to orgasm? i definetly wanna make story outta this one!

What's in HurtzlikeHell Stinging Venom? Only Doctor Pain knows, but it's pretty nasty. I wouldn't be at all surprised that there's some formic acid in it and that that is one of the.. less nasty... things in it.

Force an orgasm, with that stuff in his balls? Ooh, that might make the stuff spread around through him a bit. I would suspect the result would be internal pains of a magnitude difficult to imagine or describe. An interesting and nasty idea, that.
