Osa is a dark skin lady in her late 20's, of the Yoruba tribe in Nigeria, living in the USA. Her brother, Adunbi, and his wife, Quivina, invited Osa to join them on a vacation trip to a tropical island in the Caribbean Sea. Osa flew out separately and met them in the airport, where they took a ride service to their bungalow. Adunbi had rented a small bungalow near the beach, not far from a vacation resort, and a small shopping plaza with three stores, directly across the street from it. It's fully furnished and equipped with everything they need, except the refrigerator is empty. It has one bed, and one bath, which of course, they will all three share.
After their long journey, Osa wants to take a shower, and Adunbi agrees that it would be a good idea, while Quivina wants to unpack and get settled in. Osa strips naked and gets in the shower and is soon joined by her brother. They rinse their hair, and then begin to wash each others bodies. Rubbing soapy hands on each others backs, then each others chests.
Eventually, making there way to each others genitals, where they gently caress each other until Adunbi has a massive hard cock and Osa has a dripping wet cunny. Adunbi picks his sister up by the ass, while Osa wraps her legs around her brothers back. He presses her against the wall, as the water runs down his back he slides her down until his cock is pressed to her cunny. She reaches down and angles him so he slides into her opening, and her allows her to slip down a bit more, until he is buried all the way inside her. She bounced as he pumped, he pumped as she bounced, the sounds of there bodies slapping together could be herd in the next room. As the water stated getting cold Adunbi couldn't hold back any longer and filled Osa's cunny with his warm sperms, causing her to climax along with him.
After the sibling finished in the shower and got dressed, Quivina decided that her and Adunbi need to go shopping for food. While they are out, Osa decided to do some exploring, starting at the beach. The beach is less than a 5 minute walk from the bungalow. Once Osa got to the beach she found it had about forty or so people there, She stopped at a cabana bar and got a small snack and a bottle of water, before she turned right and started looking for a more secluded area where she could lay out in the sun totally nude.
Half an hour later, she found the beach got smaller and turned rocky, but also found a rivulet flowing from the forest. Osa followed the stream inland for 5 minutes and found a small pond created by a waterfall. She felt like this is a good place to swim and took off her sandals, sitting them on the side of the pool with her water bottle. She then took off her top, exposing her bare chest to the air. Finally, she took off her skirt, exposing the entirety her naked body to the nature surrounding her.
When she got dressed Osa had not put on a bikini, and she never wore a bra or panties. Osa waded into the pool and found that the deepest spot only came up to her chest. She walked into the waterfall, stepping onto a rocky surface she was exposed from her knees up. She leaned into the waterfall and closed her eyes as it cascaded over her. The loud nose of the roaring water obscured the sounds of two female voices getting closer to Osa's location.
