Hi, Alyssa! I am super excited to answer this question for Billy, Ryan, and, Benjamin and I put (probably too much) thought into it, but hey. It’s for science.
Billy Russo: Billy would never admit he’s ticklish, but his tickle spot is the arches of his feet. He may have walked an infinite amount of steps when he was in the military, probably ended up with some gnarly callouses, etc. but I’m sure Billy the Beaut wouldn’t be caught with rough, nasty feet. Anyway, the soles of his feet are marginally ticklish, but the inside arches themselves? Viciously ticklish.
Ryan Brenner: Ryan and his overgrown beard, sigh. My true love. When he’s more or less just scruffy than bearded, the underside of his chin down the column of his throat is his tickle spot. He can be kissed there without squirming (from tickling, anyway) unless there’s a tiny, light peppering of kisses placed there, in which case he’s laughing despite himself. (Then, there’s that start of his treasure trail just below his belly button, but that’s more or less a secret.)
Benjamin Greene: Benjamin’s tickle spots-- he has two-- are firstly, that spot just below his earlobe, and his sides. An unexpected poke of the ribs or having a hand brush his side will send him dissolving into that miserable laughter that only tickling can bring forth. He’s very sensitive to tickling.
