Mark stepped onto the beach, enjoying the contrast between the slightly cool sand under his feet and the humid warmth of the morning air. He and his wife Janet had arrived on the Caribbean island the previous evening, but by the time they had settled into the place they would be staying at for the next couple of weeks and had eaten dinner it had grown dark. Now the sun had been up for nearly an hour, and Mark was pleased to see that the beach just out their back door was as nice as it had looked in the pictures. It was also completely deserted. Mark pulled on his snorkeling gear and slipped into the water, looking forward to exploring the bay without any other people around.
It was a pleasant way to start the day. The water was comfortably warm and the bay contained an interesting variety of fish and coral. Mark wasn't an anti-social person, but he did enjoy spending time alone in nature. So he was a bit dismayed when he noticed another person swimming toward him a few minutes later. But his initial disappointment turned to surprise when the other swimmer got close enough for him to see that it was a girl in her early twenties and that she was wearing nothing but a bikini bottom and snorkeling gear. As she approached him she pointed toward the surface and then lifted her head above water. Mark raised his head, savoring the view of her perky tits until his face was above the water.
"Hi, do you mind if I swim with you?", she asked in a cheerful tone. "I get nervous swimming out here alone."
Although Mark had been enjoying the solitude earlier, he wasn't about to reject the company of a beautiful, nearly naked girl. "I'd love to have you join me.", he replied with a smile. The girl gave him a big smile before reseating her breathing tube in her mouth and lowering her face back into the water. Mark did the same and then started slowly swimming back toward the coral formation he'd been approaching before the girl showed up. She followed a couple of feet behind and on his right side.
For the next 20 minutes Mark and the girl explored a section of the bay. The girl seemed to really appreciate seeing the more colorful fish, while Mark's attention was divided between the aquatic life and the girl by his side. He didn't want to seem creepy, so he didn't stare at her when she was looking his way. But when her attention was focused on the fish and coral, Mark admired her tan, toned body, her long, flowing, black hair, and her bare breasts.
When Mark saw a particularly interesting fish or coral he would touch the girl's shoulder to get her attention and then point out the item of interest. At one point a Trumpetfish swam out from between 2 rocks. While keeping his eyes on the fish, Mark reached for the girl's shoulder so he could point it out to her. He hadn't realized that the girl had drifted a little further forward until his hand came to rest on the curve of her bikini-clad butt. Immediately realizing his mistake, he quickly jerked his hand back, afraid that the girl would have perceived it as an intentional action and would be unhappy about it. It was hard to read her expression through her mask, but she didn't seem upset. She might have even been laughing. He pointed out the Trumpetfish, and she looked at it before giving him a thumbs up gesture, her way of thanking him for pointing out something interesting.
Eventually Mark felt it was time to head back in and see if Janet was awake yet. He got the girl's attention, then pointed to himself, and then pointed back toward the beach and made a swimming motion. The girl nodded and then started swimming back toward the beach. Mark followed her, enjoying the view of her ass and legs.
When they reached the beach, they sat down at the edge of the gentle waves to take off their fins and masks. The girl had a radiant smile on her face. She started talking before Mark even had his mask off.
"Thank you so much for letting me join you. It's so stupid that I get nervous about swimming alone even in a sheltered bay like this, but I can never relax when I'm out there alone. I grew up on this island and never went swimming alone. I was at college in the United States the last year and a half, and I promised myself that now that I'm back I wouldn't let irrational fears hold me back, but I was so glad to see you out here this morning."
This all came out in a rush like she'd been holding it back for the last half hour. She spoke with a noticeable French accent, but Mark didn't have any trouble understanding her.
He answered, "Well I'm glad I was here this morning too. My name is Mark, and I'm from the United States. My wife and I are staying here the next couple of weeks."
He pointed to the back of the little house they were staying in, which was visible from where they were sitting.
"I'm Giselle. My mother and I live just a little ways up the street", she said. "I grew up on the other side of the island, and my mother just moved to this side last month. I decided to take a semester off of school to help her get settled in and to just enjoy being back on the island. Isn't it crazy that I've lived here most of my life and hardly done any snorkeling? The fish and coral down there are so beautiful!", she exclaimed while pointing out at the bay.
Mark agreed and they talked about some of the fish and coral they'd seen. Then Mark said, "Sorry about grabbing your butt while we were down there. I didn't do that intentionally."
Giselle laughed and then replied, "I could tell it was an accident. But I wouldn't have minded if it was intentional. You're a sexy man, even if you're old enough to be my father."
Mark laughed with her, thankful that she'd accepted his apology so gracefully and appreciative of her compliment. Not only was she beautiful, but she had a casual, easy-going way about her that made him feel comfortable talking to her. The only difficult part of the conversation was trying to maintain eye contact with her instead of letting his eyes wander over her body, especially her bare breasts that he was almost painfully aware of.
"Will you be back out here tomorrow morning?", she asked.
"Yes! Will you?"
"I can't wait to see more of the bay with you."
They agreed to meet at the same time the next morning. Then they stood up, and Giselle put on a cover-up that she'd left sitting on a towel on the beach. She turned toward Mark and gave him a hug while quickly kissing both of this cheeks. Mark felt a bit dazed as he watched her turn and walk up the path toward her mother's neighborhood. Once she was out of sight he walked over to the back door of the place where he was staying. He went inside and took a quick shower to rinse off the salt water and then slipped into bed naked. Janet was just starting to stir as Mark pressed against her and started to caress her. Her body started to respond even before she was fully awake, and soon she was kicking off the covers, pulling off her underwear, and guiding Mark's hard cock between her legs. They enjoyed a quick but satisfying fuck before settling down to cuddle naked next to each other.
"What got you so riled up this morning?", Janet asked with a smile on her face. "Do you just really like being at the beach, or was there more to it than that?"
