O-crunches
A sudden belly shake that happens when a woman is getting off, especially if she’s hitting multiple peaks. It’s like her stomach is doing a happy dance while her brain is melting.
During her climax, her stomach started doing the cha-cha. I asked if she was doing a workout or a party.
She did O-crunches so fast, I thought she was trying to rip her pants off.
Her O-crunches were so intense, the dog started barking at her pelvis.
