In sonic x does cream and tails kiss

no. tails and cosma kiss though in the second to last episode (might be last episode)

No they didn't, i know for a fact that they don't because in the episodes preceding the second to last episode, Cosmo sacrifices herself to the Metarex to save the universe, her seeds scattered throughout the galaxy and tails turned into a whining crybaby. Cosmo left before they could really say goodbye, but they never did kiss, they got close though in the one episode in the cave where Tails got hit in the head with a rock and passed out.
