Characters with more than two arms have a chokehold on me. It's a fantasy that's stuck with me since I saw the Caterpy scene from DBZ. Over time it's basically turned into a gang tickling fantasy. But being able to essentially have a gang tickling session with just one other person is really appealing. And there's so many ways to go about it. The classic pinned by the wrists and ankles while the extra appendages do the work. Maybe two people with four arms are holding you down at either end. If you want to be a little sadist you could even envision yourself strapped down tightly to a table by metal shackles. That way if a creature like the earlier example of Caterpy is sicked on you then you have no way of protecting yourself. Imagine the agony of being poked, stroked and squeezed and being unable to anything about it. You squirm and laugh while ten arms work you over. Two are making circles with their index fingers in your armpits. Four are just mercilessly playing with the softest most sensitive parts of your tummy. While the remaining four work over your legs and feet. Meanwhile this big green jerks dumb face is smiling at you and verbally teasing you. Making your already weakened state of mind worse. Sometimes they focus all arms on one spot just because he can. Could you imagine? All those arms having open access to your tummy, ribs and nipples? On top of that, those index fingers are still doing damage to your poor underarms. It uses two hands to hold your toes back while the other eight hand lay into your sweaty, oiled soles. You didn't even know feet could be tickled like that til this encounter. Tickling you until exhaustion and then some. And since you seem to be having such a fun time, Caterpy doesn't see the need to stop. Your screams only stopping when you give out from exhaustion.
