The following day, there was a tension that persisted throughout the atmosphere aboard the luxurious yacht. Sandra had been trying to slip away with Allyson the whole afternoon, and Ryan and Alexis had been trying to inconspicuously reassure one another about their previous dayâs activities. Simone and Allyson were the only ones who fully understood the reasons behind everyoneâs edginess. Allyson was not quite ready to try and bring Sandra round to the idea of her son as a sexual partner and wanted to have another go at the motherâs pussy before turning her over. She called Simone to the bridge to arrange for some alone time.
When the young woman entered the doorway, Allyson quickly gave her the instructions.
âI need you to take Ryan and Alexis diving. They seem to want the opportunity to be alone and I want Alexis to be more open to the idea of having another woman around during their escapades. Take them scuba diving, but go without the wet suits. Show them the sights. That is all.â
Simone was a little angered about being so quickly dismissed. Despite her subservient role in the relationship with the older woman, she still felt more than a bit of ownership towards her. And she had been less than thrilled when she had been told that Sandra had been the recipient of Allysonâs tongue lashings. And now she was to baby sit the fucking siblings while Allyson took advantage of their mother. She paused momentarily, thinking of offering some word of challenge to the plan, but her resistance folded before it even began.
She returned to deck and relayed the information to the family. Ryan and Alexis both shared a knowing glance before responding in the affirmative. Sandra felt her stomach do a nervous back flip as she realized she would once again be alone with the woman who had pleasured her the day before. Some part of her wanted to resist the excitement which filled her stomach, but it was weak and could not battle the natural urge of her pussy.
Ryan and Alexis had slipped below decks to gather the scuba gear when Simone reminded them to administer the injection prior to diving. The young couple shared the same glance that they had above the deck and retreated to the cabin. Alexis entered first and held the door for her younger brother. Once he was inside, she pressed the door shut and coyly leaned against the door. Ryanâs body crushed into hers and his hand hastily roamed over the many curves it had longed for throughout the night. The couple broke apart seconds later and Alexis flung herself face first on the bed.
She wiggled her hips suggestively as she unnecessarily pulled her bathing suit bottoms down. With her ass raised in the air, she waited for her brotherâs touch. Alexis would not have to wait long for Ryan. Standing by her side, Ryan slipped one hand between her thighs while the other prepped the needle. Alexis hissed as she felt the caress of his fingers against her naked pussy. They gently stroked over her sensitive outer lips in a slow circular motion. The sensation was so enticing she did not even feel the needle press into her skin and deposit its load into her tissue. She did notice however when the fingers abandoned their teasing approach and she was left with her ass in the air and a very warm sensation emanating from between her legs.
Frustrated she rolled over onto her side as she fished her bikini bottoms back up. âJerk,â she muttered for Ryanâs benefit. He gave her his cute lopsided grin and licked his fingers clean. Then he pulled her from the bed, a noticeable tent in his shorts. Together they nonchalantly returned to deck. Their mother was no where to be seen and Simone was waiting for them off the rear of the yacht.
Alexis was a little peeved to see that Simone was wearing a very revealing white bikini that was really more string then fabric. She let her body language do the talking for her as the scuba tank was hoisted onto her back and Simone covered the basics of diving once more for their benefit. Then the siblings and their escort slipped beneath the waves into the silent alien world of the ocean.
Ryanâs erection would fade as they swam deeper into the clear water. They were still not far from the island and were anchored over a shelf that extended from the islandâs base. They were down about fifteen feet when they first saw the beautiful dark blots of the coral reef beneath them. Alexis whirled to her brother, one hand frantically pointing at was already obvious. The world beneath the waves was entirely foreign to the one above it. Strange and beautiful fish swam amongst the abstract growths of reef and sea life. For a while the trio forgot the other desires they had hoped for and enjoyed the uniqueness of this new frontier.
Their path took them back towards the boat and soon the party found the anchor and its chain as it shot from the sandy floor towards the glistening azure of the world above. Alexis grabbed onto the chain and with a hearty kick of her fins, pushed her body in a looping circle around it. When she came round, she ran into Ryanâs chiseled form, lazily kicking beside her.
The brother and sisterâs bodies pressed to one another as a single hand extended from each of them to the anchor chain. The other hand had more interesting things to hold onto. Ryanâs hand slipped behind his sister and inside of her bathing suit. Alexis found her crotch pressed to his, as his hand caressed her buttocks for the second time that day. Her own hands waved in the water, slowly, as she kept herself at the same height as her brother.
Ryan pulled his sister as close as possible and pressed his hand farther down into her bathing suit, his fingers feeling for the familiar hole which longed for them. Alexis moved just higher than him with a small flutter of her fins and his fingers slipped into the warmth of her opening. Alexisâs arms wrapped around the back of his head and pulled his mask to her chest as his fingers churned within her. Her legs now hung limply in the salt water as the small extremities of his hand twisted inside her.
Ryan was not in a patient mood and wanted his sisterâs warmth on his penis and not on his hand. Once he was certain that she was wet and wanting he worked to pull his shorts down beneath his balls. Alexis caught the motion and walked herself back down the chain with her hands until his penis was trapped between her thighs. Ryanâs hands pulled the bikini bottoms to the side and gave his phallus the opportunity it needed to hit home. For a moment the dark red of his tip and the light pink of her pussy stood out against the light blue of the water and sand beneath them. Then the tip disappeared into her body and the brother and sister were united in body once again.
Everything was slowed underwater. Ryanâs strong urgent thrusts were slow and patient. Alexisâ twisting hips proved to only be softly gyrating. The world shut out all sensory experiences but for the echoing waterâs embrace and the exploration of Ryanâs cock within Alexisâ pussy. The young couple braced themselves against the chain as they tried to fight the waterâs subtle strength and truly enjoy the freedom of passionate sex. Alexisâ pussy was much warmer than the surrounding water and that became the focus of Ryanâs mind- the return to the heat of her clutching walls. The same was true for his sister, her mind could only focus on the heated burrowing of his length within her.
Below them near the ocean floor, a jealous and highly aroused Simone circled. The two young people above her had been completely ignorant of her presence from the moment their skin made contact. Now she was the unwanted voyeur. The part about being unwanted bothered her; Allyson had dismissed her and Ryan had ignored her. The voyeurism and the strange ethereal effect of the water was profoundly arousing. Now she swam around the chain like a predator, her gaze never faltering from the union of the siblingsâ intercourse. From ten feet below she could make out the slow wave like rock of Ryanâs balls against his sisterâs thighs and the disappearing of his white shaft into her pink depths.
It did not take a great deal of time for Simoneâs body to demand treatment of its own needs. She returned to the chain to which the brother and sister clung, wrapping her own thighs around the heavy metal links and pressing her body into its stiffness. Her pussy ground into the cold steel surface, the flat portion of a single link tracing her pussy lips through her bathing suit before another would slip into place. Her labia embraced the rough chain between it and soon her hips were jerking quickly over it. From her new vantage point even more details of the siblings were available and she devoured each of them.
The young brother and sister soon discovered that pleasure was most readily achievable if their movements were less pronounced and more focused in the region where penis and vagina met. Alexisâ hips cycloned in the water as Ryan rocked his penis in and out of his sisterâs twat. The swirling motion of her pussy on his cock was intensely arousing as pressure would become pronounced in one area and then in another. Some form of suction had come into being within Alexisâ channel as a small bit of air fought the invading force of Ryanâs phallus and the salt water it brought with each thrust.
Ryan came first this time, his semen spewing volcanically into his sisterâs womb. Load after load of his bodyâs liquor squirted forth. The addition of this new liquid heat would bring Alexis to join him beneath the waves, their embrace tighter than ever before as their bodies celebrated their sexual union. The water around them warmed at the sudden introduction of Alexisâ fluid to the environment and they relaxed in the bath of their own creation.
