I'm writing a story for homework and talking as a snake

and i need to know how the hiss with the extra s's sounds.

if i should add extra s's to each s in each word

here is a sentence

“Hello Ssssebastian”

simple just the one word but longer sentences might be weird

“Sssso Ssssebastian, I’m guessssing most people osssstracize you because of your golden hair. I wouldn't Ssssebastian, I wouldn't. I love your golden hair."

doesn't that sound weird?

should i only emphases the s's in Sebastian?
