Naomi does

Naomi shifted her weight forward, and stood up from the deck chair. She fingered her own cunt as she stepped toward Pete. She knelt down at his side, and put her fingers near Pete's face. The smell aroused him, and he raised an eyebrow, though his eyes were still closed.

"Naomi?" he asked. He realized the smell wasn't Andrea, and he wasn't entirely certain who else was there.

"Mm-hm." Naomi slid her fingers into his open mouth, and he took them eagerly and sucked. Naomi noticed a twitch in his pants, and reached her other hand down the front of the swim trunks and grabbed hold of his cock. She stroked it, and felt it get very hard very quickly. She assumed that Pete and Andrea had fucked that morning (though she didn't watch this time, she often saw them fucking in Andrea's bedroom), and was delighted that he was able to bounce back so quickly. Naomi took her pussy-soaked hand from Pete's mouth, and then with both her hands, pulled his shorts off. His cock sprang to attention.

Andrea sat back on her chair, her hands still poking around at her own pussy. She watched as Naomi stood, lifted a leg over Pete's body, straddled him, and slowly lowered herself onto his cock. She was facing him as she aimed his dick into her wet pussy. They each moaned with pleasure upon penetration, and Naomi began to bounce up and down. Pete put his hands on her breasts, holding her soft, round tits with his strong hands. He touched her stomach, and slid one hand toward her pussy where he thumbed at her clit while she fucked him.
