It may not seem like much, but a tail coil can be a lot more of a bully move than it seems at first.

Sure, the woofer here, Sora, is being tightly squeezed via tailcoil and locked in place, any attempts at squirming free only make the binding loops tighter thus easily claiming him as mine.... but why stop there?

This can easily lead to carrying my new tailpet around with me for a bit of exhibitionism and teasing, letting everyone including his friends see him so helplessly bound being dragged along by dergtail, having that dergbooty constantly wiggling in front of him, only stopping once the derg now wants to sit down to rest. Oh and look at that, he'd have a seat to rest on whenever he wants! Tailcoiled up means portable seat! (see prior pics)

Maybe you've got nothing to do though, having someone coiled up in tail means you always have someone there to tease and play with, even when relaxing! Hard day at work? Just sit down and rest your worked paws on your coiled victim and maybe give a few kneading playful rubs, and if you're feeling extra teasy and dominant, ask them to clean them.

Maybe they're getting too loud in their protests and demands to just let them go already... well now's the time to finish the coiling and cocoon them up in a mass of tail loops! Muffled silence will come and you'll look like you have a thicker tail instead of a long one as the coils seem to merge together into but a swirly pattern. No one would know someone was sealed away inside now used as a tailthickening device.

I could go on and on about more ways to bully someone with tailcoils, but they'll come in due time.
