Andrea does

Carefully, Andrea slid out from behind Naomi, and got off the deck chair. She continued to finger her own cunt as she stepped toward Pete's chair. She knelt down at his side, and put her fingers near Pete's face. The smell was enough to arouse him, and Andrea could see a twitch in his pants. Pete smiled, took her fingers in his mouth, and sucked on them.

Andrea put her other hand into Pete's shorts, and grabbed hold of his cock. She stroked it, and felt it get very hard very quickly. They had just fucked that morning, but Pete was always able to bounce back quickly. Andrea took her pussy-soaked hand from Pete's mouth, and then with both her hands, pulled his shorts off. His cock sprang to attention.

Naomi sat back on Andrea's deck chair, her hands still poking around at her own pussy. She watched Andrea as she 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 Andrea began to bounce up and down. Pete put his hands on her chest, her breasts, touched her stomach, and used his thumb to poke at her clit while she fucked him.
