Ahh yes, tentacle porn... not really my cup of tea.
Though I can appreciate the occaisional tentacle flick I suppose.
But it seems to me that what I searching for specifically is a monster themed pornographic series, where it's not monsters on girls, but monstrous girls on guys... and girls too! There's just not enough of this on the web, either as live action or animation, and I think it could be a really good marketable niche, if done correctly!
