Underwater surprise
Draco was enjoying a hot and sunny summer day at the beach, which was just a few dozen meters from his private summer mansion.
There was no one to be seen in the vicinity, so he took the freedom to shamelessly strip off his swimming trunks, allowing sunrays to reach his intimate parts.
After a while it became too hot for him. He lazily got up his sweaty self and sat on an underwater rock, the sea level just above his waist.
He opened a can of beer and slowly sipped the refreshingly bitter beverage.
When his body cooled he wanted to return to the mansion, but his legs wouldn't move. He looked into the water and screamed, but there were no other human beings on the island to hear him.
A giant octopus has clung to his legs with its muscular tentacles, and spread his legs. The animal directed two tentacles towards Draco's reproductive organ and suck onto it. The blonde boy struggled, and the movement created a strange, pleasurable feeling. He started moving his hips rhythmically, but suddenly he paused. He felt something else. Something elongated. Slippery. He sat on sea cucumber that was contorting between his legs and started penetrating Draco's virgin hole. Once settled, Draco's struggles to free himself triggered the sea cucumber's defence mechanism, and the slippery animal started to swell inside him.
He groaned in pain and pleasure and started rocking his hips.
Meanwhile, the octopus' hold of Draco's hard member tightened. It used two tentacles to push the cucumber in and out, and wrapped the remaining ones around the boy's muscular torso.
The cucumber spurted a thick white defensive liquid into Draco's abused hole. Draco followed suit, the octopus greedily ate all his semen, tightened the grip it had on him and dragged him underwater to finish the mating process.
Salt water filled Draco's lungs and he started choking. He fought furiously against the animal to no avail. His body urged him to inhale, but the octopus has been dragging him against the seabed. As he tried to inhale, algae filled his mouth and sea urchins' spikes pierced the skin all over his body.
The smell of blood attracted a shoal of sharks… Leaving only his skeleton behind.
...
And up 'till now Draco's skull still serves as shelter to the sea cucumber.
