I’m no expert.
“S’il vous plait” means “if it pleases you” and is purely a formality. You wouldn’t really repeat that. There is a circumflex on the i, which I am too lazy to include.
“C’mon, c’mon, do it! I beg you!” might be along the lines of “Allons, allons, Fais-le, je t’en prie!”. “I would like to please you”: je voudrais faire vous plaisir.
“Stop that. Stop. Bad.” might be along the lines of “Fais pas ca. Arret. Mechant(e).”
