I can't say about the manticore, but the Giggis bone structure in the neck and tail has atrophied. The vertebrae are still their but the joints are comprosed of stretchy and flexible tendons and cartilage. Most of their ability to support weight in the tail and neck comes from some very powerful muscles.

The muscles in her tail pussy are quite dexterous so she can massage you in any way she pleases amd squeeze you tighter than a baphomets vajayjay. And to answer your question, yes, she can very easily do a good old spin cycle on yer dick without risk of injury.
