Josh caught Stephanie out the corner of his. She stared at her brother as he stared at their mother. Stephanie knew right away that Josh was eying their mother’s sexy body.
“Josh, would you be a dear and rub some of this lotion on my back?” Helen asked, without expecting him to refuse. Josh squirted a heavy amount of the oil into his hand and then began rubbing it onto his mother’s back. He quickly finished when he found himself being aroused.
Stephanie dropped her shorts and then pulled off her t-shirt. “Race ya to the water, Josh!” Stephanie started running before Josh had a chance to react. He figured he had better do something before his mother saw the chubby forming in his shorts.
A few seconds later, Josh joined his sister in chest deep water. The waves were small enough that they could maintain their balance in the shallow water. Josh and Stephanie glanced at each other and the glanced toward the shore. Helen lay on her stomach, facing away from the ocean. Josh reached through the water until her found Stephanie’s hand and then pulled her tight.
“What are you doing?” Stephanie asked, alarmed. “She’s right there. She can see us.”
Josh planted a kiss on his sister’s lips. After a brief moment, he pulled away. “She’s not even looking this way. Besides, I thought you like the idea of getting caught.”
“Okay then,” Stephanie said, flashing a teasing smile. “Lets play then. Give me your shorts.”
Josh immediately regretted what he said. Then he had second thoughts. “Give me your top,” he said.
Stephanie quickly untied her top and went one step further and slid off her bikini bottoms too. “Here, you can have both of them.” She handed out to her brother’s
Josh quickly snatched her bathing suit before their mother saw. He pulled off his shorts, but held onto them. He smiled at his sister and then ducked under the water. He swam around Stephanie, groping her. Josh ran his fingers between her legs and then up her back before reaching around and squeezing her tits. Stephanie felt blindly through the water until she grabbed his hard cock. Josh let go of her and resurfaced. But, Stephanie didn’t let go.
She started stroking her brother, getting him harder. They stayed as far apart as they could, but remained in arms length. They tried to be cautious just in case Helen would look their way. Before they realized it, they ignored the shore and were chest to chest. Josh was as hard as he was ever going to be. Stephanie wrapped her legs around her brother’s waist and then hoisted herself on him.
Josh slipped inside Stephanie. Josh maintained their balance as Stephanie began moving up and down on her brother’s ten inch cock. In a matter of minutes, the entire world faded and they didn’t care who saw them. They weren’t stopping until they were both finished.
The excitement of being in the open water and their mother than fifty yards, Josh announced his climax in just ten minutes. Stephanie climbed off her brother and stroked him until he finished spurting his cum into the Atlantic Ocean. They were about to kiss when they heard their mother. The siblings quickly pulled apart and looked toward the shore. Helen was waving for them to join her.
