I'm usually restrained, usually on a table so it's safer. However, I can take or least I'm small, and some of the people who tickle me, just hold me down, and I don't have the strength to get away anyway. I've got one one woman who tickles me, and she can hold me with one arm, tickling me with her other arm. Or maybe just keeping me in control. I don't even understand it, but she's so strong or I'm so weak, lol, that I can spin around whatever, she never loses control of me.
You ever see that video where Layla Moore is tickling Cupcake Sinclair on the couch, it's like that. Though me and Ana, have a bigger proportional difference.
It might actually be more enjoyable. Because I've got a complete free range of motion, but I have no way of getting away. And on the off chance I do get away, she pulls me back, so it's like even more like hyperactive and exciting. It's definitely rarer than being restrained.
Being restrained is beneficial for my internal roleplaying thought process that I sometimes go into, it's easy to pretend like I've actually been captured and are will never be able to get away which can increase enjoyment. I like both, more or less equally I guess. Though not being restrained might be slightly more enjoyable.
