Mack walked onto the beach in his swimwear. He looked around and noticed there was nobody else on the public beach. He knew why that was, and he just smiled. "Heh. A public beach all to myself. Perfect. Not even the lifeguard is on duty." He walked up to the water with his surfboard, intent on spending a day on the water. 

Before the strong tan 25-year-old man could get into the water, he noticed a giant sandcastle. The castle was a good three feet tall and looked very impressive. He wondered who could have built it. "We're trying to stay away from the public places people!" Mack called out. "Shouldn't be building sandcastles on the beach!" He raised his bare foot and stomped out the castle with ease.

Mack didn't realize that it wasn't humans that built the castle, but small fairies that quickly flew out once he stomped it flat, but he didn't notice the small things fly out from the castle, which was very fancy inside. 

The many fairies all looked at Mack angrily, and then looked at each other. They all nodded, and flew to Mack.

Mack felt a presence fly around him. To him, it felt as if multiple gnats surrounded his body. He swatted them and tried to smack them against his bare torso, but to no success. "Ugh, what's going on?" He kept swatting around his body. With a roll of his eyes, he began to walk to the water. He'd get rid of these flying things if he went underwater.

Mack felt a strange sensation at his feet. Had he looked down, he would have noticed his bare feet taking the color of sand, but also growing very thick in size. He placed his feet into the tide, and he felt the water brush at his feet. The moment the water touched his feet, it felt as if he lost his heels and his entire balance. He fell down with a shout and a thud. "ACK!" He raised his feet in the air and glanced back at them. He turned around and was horrified to see his feet were gone.

He noticed there was no blood from his lack of feet though, nor was there any pain. He moved his ankles back to the sand, and he stared as his feet came back, but as large feet that looked better on a large anthro creature. He stood up with his new feet, and then turned to his surfboard. "I uh...I guess I'll be going now."

One of the fairies floated up to Mack's ears and whispered. "You're not going anywhere. You're going to be our new home!"

Mack froze as he heard the voice. He turned to his left, and then his right. He looked down and noticed the sand build upwards his body, as well as fat. "What the hell is going on?" He even felt the sand affect his crotch. He pulled down his swimsuit and noticed his cock vanish with only a bare crotch of sand between his legs. "My legs! My cock! What the hell are you...whatever...doing to me?" The voice in his ear sounded high pitched, and he heard giggling all around his body.

"You destroyed our home, so now YOU become our home." The fairies spoke as they flew around Mack. More and more of his body turned to sand, but he also looked fatter with the new sand. Some sand occasionally fell from Mack's body, but as long as he had his feet on the beach, it just simply reabsorbed into him.

Mack felt freaked out. He was turning into a sand golem of sorts, and these flying creatures were changing him. He tried to get off the beach, but he fell face first into the dry hot sand before he could get to the grass. He raised up his head and felt sand pour out of his mouth. It didn't take him long to realize it was the sand up to his now flabby torso. He felt something stick to his face, and as he reached up to feel it with his sand hands, he felt two large buckteeth. There was a large gap between the teeth, but they went all the way down to his chin. "What the hell?" He shouted angrily. He knew no human had teeth so buck. He was now glad there wasn't a sign of others on the beach to see his new bizarre body.

"Humans are too boring." The fairies said. "You need to be a walrus!"

Mack felt fairies 'enter' his body now. He looked down at his chest and saw gaping holes that he could see right through. He tried to cover it back up with sand, but the sand didn't stay. He looked back to the water and knew wet sand worked out better than dry, so he ran over to the wet sand and tried that instead. He got close enough to the water to see his reflection, and he was mortified at what he saw.

Mack saw not a human face in the water, but the face that fit a walrus. His nose and mouth jutted out only slightly, but he saw the two large tusks on his body. He saw that his eyes were also sand, just like the rest of his body. He was from head to toe a sand golem, and one that lacked a gender. He could feel the fairies inside of him building and molding him into whatever they wanted, and as much as he tried to restore his body, he couldn't do anything about it.

"If you're not going to cooperate, then we're just going to remove your ability to move for a few years until you learn to like it!" The fairies said from inside Mack's head.

Mack's eyes widened, and he opened his mouth to disagree, but it felt as if the fairies paralyzed him the moment his mouth opened. He could feel the fairies adjust and move his body how they wanted. They shifted him to lay down on the beach in a 'sexy' pose with one hand on the sand and the other on his fattened walrus anthro torso. They hollowed out various parts of him and fattened him up as they needed to in order to get a home good enough for them to live in, and Mack could only lay there as the fairies made him their new home for not even he could guess how long.
