Her own

Andrea left one hand working Naomi's nipples, but brought her other hand back to her own body, and touched her pussy. She was already pretty wet, plus her hands were slick with sunscreen. She easily slid one finger deep inside her cunt, and finger fucked herself.

As Andrea began to pulse against her own hand, Naomi felt the rhythm and matched it. Both women used their right hands and were grinding against them. Naomi's hand was inside the bottoms of her bikini. Andrea was naked.

Almost perfectly in sync, they each went to two fingers. As Naomi did this, she stretched her pinky back, and reached for her asshole. It wasn't the best angle, but just striving to touch more than her pussy was exciting. Andrea continued the straight finger fucking. She added a third finger, and continued to push deep into her snatch.

Naomi pulled her fingers out of her twat, adjusted the angle of her hips, and dug a wet finger into her asshole. She needed that different stimulation. She alternated between poking at her ass and her pussy, closing her eyes and imagining that it was Pete's cock doing that exploration.

Coincidentally, Andrea was also daydreaming of Pete's cock, and how earlier this morning, he had surprised her in bed by sliding it into her pussy while she was still asleep. She smiled. No wonder he's so tired now, she thought. She flicked her clit and dug into her pussy, each thrust imagining her boyfriends hard dick instead of her hands.

He was right there, she could simply climb onto him if she wanted to. She didn't know for sure, but she imagined Naomi may very well be having similar ideas.
