Not 'on the way'...

They made it to sand, much easier on their feet, and Jenna took off at a sprint. Selena walked faster, but wasn't in that much of a hurry. She took in the scenery. The island was truly beatiful. As she looked out across the sparkling sand, she say some oddly shaped, and oddly colored, mounds in the sand. She started towards them when Jenna came sprinting back towards her. The girl was running past one of the mounds when something sprang out of the sand, knocking Jenna to the ground.

The girl, now dazed, started getting to her feet when it grabbed her arm and pulled her sideways. I looked humanoid, but clearly noy human. The muscles look stringy, but clearly weren't. Its skin tone seemed to be changing, try to adapt to its surroundings. Then she saw the second one. It had been hiding not far off, but now came dashing across the sand.

Jenna was frantically trying to push the first off when second grabbed an arm. She squeeled, and as her attention shifted, the first ripped off her bikini bottom. Both creatures grew large hard ons for their size (they were just under 4 foot tall) and the thing was desperatly squeezing itself between her legs. She tried pushing it off, but with both hands necessary for the job, the second moved right in front of her. It grabbed the girls head and **** its engorged member into her mouth. It started humping like a jack rabbit, and Jenna needed both hands to push it's crotch back enough it wasn't in her mouth anymore.

Now resistance free, the first got on top, grabbed her hips, and thrust into her. Again, it immediatly started hammering away. Jenna flailed her arms. She was petite enough the thick shaft was actually pretty large to her, and the intensity was overwhelming. The other grabbed her head again, but she turned away, causing it to rub its throbbing cock against her soft cheek.

Selena was in shock at first, but now screamed out. She started to run to the other girl when she caught motion out of the corner of her eye. There were more coming out of the cave. She needed a weapon. She ran to were everyone had gathered on the beach and found some sort of pipe. The other girls were shouting questions, but not coming over. She told them to get off the beach and sprinted back to help her friend.

When she got back, there were six creatures. There was one holding each arm and each leg, keeping her from getting up. The one that was fucking her tensed up and Jenna's eyes got wide as it started pumping its cum into her. It finally released her as the other free one tried pushing past it for it's turn. She twisted her body to close up to exposed spot between her legs, but the lust driven thing just **** it's cock into her butt instead. She tried to turn back, the the ones on her arms threw themselves on her, pinning her down. Selena watched as the vile creature fucked the poor girl's slender young butt, thrusting in and out with rabid ferosity. Soon, its legs tensed, and it pushed in to her as hard as it could it shot its load into her.

Selena didn't know what to do. No one had come to help. Jenna wasn't struggling any more. They pulled her legs apart and another had his turn, shoving its absurdly thick cock into her, humping her like it was mad.

"Jenna... I'm sorry.... I don't know what to do....!" Selena backed away, then ran to the others. The panicked look on her face finally got them moving. They jumped into the jeeps they used to get down here, and drove back up to the resort. Selena was bombarded with questions, her only answers sounded hysterical. They calmed her as best they could, then had their own meeting. They should be on alert, but.... monsters? That didn't sound right. They needed to solve this mystery.
