The thirst is real for Blac Chyna ... luckily she had a big bottle of water handy to quench it during a very curvaceous Malibu photo shoot.
BC hit the beach last weekend in a tiny fringed bikini with her long hair blowing in the wind ... not that you were paying attention to that.
It's been a wild couple of weeks for Chyna -- date nights with a much younger guy, one sex tape leaked followed by another way more graphic one ... which turned out not to be her.
Looks like she wants to give us a friendly reminder of what her most definitive feature really is.
