Amber Rose & Blac Chyna's Trinidad T&A Party Don't Stop

Amber Rose and Blac Chyna are still in Trinidad ... feeding orphans and building local schools.

KIDDING, of course -- they're really just keeping the party going post-Carnival in the lowest of low-cut tops and anything that hugs their asses ... which is everything.

We got shots of them all over the island. It's the perfect ass Wednesday chaser.

FUN FACT: Ass worship really does pay, if you buy what happened to the guy in this video when he got pulled over by a cop. Yep ... Amber could get you out of a ticket someday (but don't count on it).
