The creature

The creature watched the voluptuous blonde woman smear the thick cream all over her tanned skin. It had no idea of what it was that Sandy was doing, but its reaction to the sight of her was to become aroused.
While the creature had instantly began to lust after Sandy upon first laying eyes on her, it was still cautious of the strange vessel in which she had arrived, and was therefore not yet to approach it.
What it did do however was what it always did when it became aroused; it produced an ample amount of pheromones. Due to the direction of the wind, the cloud of pheromones began to drift towards the boat.

By the time that the colourless agent moved in over the fore of the ship, Sandy had already finished with the sunblock and had reclined into laying on her back, her massive tits spilling out over the sides of her ribcage.
Sensing a sweet smell, the source of which was unknown to her, Sandy rose back up again and looked around, but failed to see anything. She took a deep breath, sucking in the air through her nose, and became certain of the smell really being there rather than a figment of her imagination.
Suddenly, Sandy began to feel flustered while her nipples began to harden and a familiar sensation began to manifest itself in her loins.

Sandy wasn’t usually all that keen on stating the obvious, but now she couldn’t avoid letting out a perplexed “I’m becoming horny!”

This was very odd, Sandy thought to herself, but then she relinquished hold of her reason and released a throaty moan as her hands came into contact with her breasts, her sensitive nipples suddenly being caught between her fingers.
Moaning as she squeezed her nipples for a few dozen seconds, Sandy soon decided that the top of her miniscule bikini was blocking her access to her nipples, and the top was therefore removed by her, her full, firm breasts jiggling a bit as they lost all the support that the tight top had given them.
Rubbing and caressing her nipples, Sandy still wasn’t satisfied, and the consequence of her lack of satisfaction was her lifting her right tit up to her mouth so that she could on it, tenderly stimulating her nipple.

This still left her unsatisfied, and Sandy finally went all in by burying her right hand into her bottoms, spending only a few seconds rubbing her thoroughly soaked twat before stabbing two fingers into her fuckhole.

Her sex was far wetter than what she was used to, particularly so as she had barely had time to stimulate it, but Sandy didn’t reflect on that at all, instead choosing to thrust her hips up into the air, having resumed her prone position a while back, and began fucking her hand like it was the cock of some lover that had positioned himself on top of her.

Axel was currently in his small quarters below deck, furiously whacking off as he imagined Sandy slowly peeling off first the top of her bikini, and then the bottom, when he suddenly heard her scream. At first he thought that the screams were just part of his imagination, but it quickly dawned on him that she was actually screaming.
Roused into letting go off his erect cock, Axel turned round and began to rush towards the door at the same time. This is in itself was a bad idea, but it became an even worse one due to him rushing straight into chair standing behind him.
Letting out a surprised yelp, Axel crashed over the chair and fell haplessly towards the floor, upon which he landed with an unceremonious thumping noise, the impact of his body onto it causing him to burp out all the air in his lungs.
