Is their tickling unrelenting? I'm thinking of buying some of their videos.
I might not be the most unbiased person here, but I'd like to answer that question anyway, if I may.
The intensity of the tickling varies quite a bit from one video to the other. Some are quite intense, with ticklers who do their job apparently without mercy. But others are more on the moderate, playful side. While the intensity is in part influenced by the skill and ruthlessness of the ticklers, it also has a lot to do with the ticklishess of the ticklees, which, again, varies a lot. Then again, a model might be very ticklish but have relatively mild reactions. Or she could be moderately ticklish and yet laugh her ass off. Each person is different.
Anyway, if you're asking about my work in general, I would have to say no, I can't really describe the tickling in my videos as unrelenting, because it doesn't apply to all of my videos. Some of them might be to your taste. But to be perfectly honest, if you're considering buying a number of videos hoping that they all feature brutal, excruciating tickle torture, The Last Laugh might not be for you. I say this in all honesty.
Then again, you could always pick a few of the more intense ones if you want.
