They don't have to

Hilary marched up to them and shoved her board into the sand. She put her hands on her hips. When she did, she only felt skin, not cloth. She looked down and shrieked. She put a hand over her crotch and an arm over her breasts. She then saw the women filming her.

"Stop it you, you...you...lesbian dyke sluts!"

"Did she just call us what I think she called us?" asked the Latina.

"She did!" said the tall Asian.

"Get her!" said the short pale skinned woman coated in sunscreen.

The women attacked and knocked Hilary to the sand.

"Get off...hmmmmphh!" The Asian clamped her hands over Hilarly's mouth.

"Turn her over!" said the pale girl.

They flipped Hilary onto her stomach, and the pale girl took a handful of wet sand and rubbed it into Hilary's crotch and between her pussy lips then took another handful of wet sand and rubbed it into Hilary's ass crack as the naked women squirmed and moaned into the gag.

The latina got up and grabbed her sari. She ripped it and came away with two strips. With one they tied Hilary's wrists behind her back and tied her ankles together.

The women lifted Hilary and dragged her away from the surf. They dug a shallow trench, pushed Hillary into it, and covered her in sand, rubbing one last handful of wet sand into her scalp. When the were finished, the gagged her with a another strip of the torn up sari and left her with only her head sticking out of the sand.

"See you, bitch!" they took one last photo and left.

"MMPPHHH! HHUUUUU MMUUHHH!" Hilary twisted back and forth and some sand fell off her breasts. The sand in her pussy and ass crack was very, very irritating. She heard male voices heading her way.
