An Island of Dreams [mff] [incest] [series]

Calling it beautiful didn’t come close to describing the paradise Logan found himself in. Closing his eyes, he breathed deeply of the salty sea air, feeling perfectly content, with just that twinge of all to familiar longing he felt near his sisters. He was slightly envious of their closeness. They were still single, much to mother’s chagrin, and something Logan could relate to. His most recent breakup was still a fresh wound, which is what inspired this remote island get away. His sisters understood him better than anyone in the world…
The sound of laughter and splashing further down the shoreline drew his attention back to the moment. Sandra and Mallory were swimming fearlessly into the crystalline waves, shouting for him to join them. Logan jogged towards their cast off gear, stripping his shirt to reveal the lightly burned, handsomely chiseled features. He plunged effortlessly into the waves, the water around him muffled his senses and he allowed himself to be lost to the wonder around him. The swirling sand and shimmering schools of fish made it seem like the world had slowed down just so he could try in futility to absorb it all.
A sharp pinch on his ankle jolted him from the daydream, he sputtered to the surface, followed by a maliciously grinning Mallory. “Jesus christ, you scared me to death, kid!”
She only laughed, “I thought maybe you were trying to grow gills under there”, but Logan wasn’t paying attention. Beneath the blinding reflection of the water, he could see her perfectly naked body treading gracefully. Mallory, though three years younger, was tall, dark, and powerfully built, testament to her different biological father. Despite being only half siblings, Sandra and Logan loved her dearly.
“What are you doing?” Sandra’s lips tickled his ear, startling him to realize he had been absent-mindedly reaching for Mallory’s exposed breast.
He stuttered for an answer.
“She’s talking about these” Mallory swam close to tug on his belt loop, “Swimming with such heavy clothes on must be hard.”
It wasn’t the only thing getting hard.
