Cardi B's Quest To Get Birthday Sex

CB celebrated her 26th bday Thursday night in Los Angeles at an album release party for Offset's cousin, Quavo ... and the "I Like It" rapper looked like a leopard in heat as she teased her hubby with some textbook booty shaking. Rawr!

The club was packed, and Offset had the best seat in the house as Cardi twerked the night away.

Cardi made it clear she wanted to end her bday with a bang ... and we're confident she got her wish. Let's be real, there's no way Offset's turning that down!
