2. Pred, prey, or switch?
Personally I am mostly a prey, but I do have rare moments where I wouldn't mind swallowing someone and keeping them safe and sound. I perfer the prey side of things for a lot of reasons but I can also see how the pred side can be so appealing. So I wouldn't really consider myself a switch with how much I enjoy being a prey but I do get the occasional craving to hold someone that close.
This really depends on how comfortable I am with the people, I wouldn't mind being in a tummy with a really good friend to keep me company and cuddle with, like a sleepover. But if I were the pred in this situation I think I'd be a little bit more hesitant but as long as they enjoy it and are comfortable I think itd be alright.
YES! Teasing is so cute and wonderful from either side. Preds who tease their preys by saying "I'm gonna eat you!" or making small remarks that are an inside joke between the pred and prey and no one else understands. Or a prey who loves to be mischievous and knows how to get a reaction from the pred and gives them a gentle belly rub from the inside when they hear the pred talking because they know it's gonna make them stutter and mess up their sentence.
