#3 of Sakura

Tentacles are spooky, right? No? Well, I already did my Halloween story last week so here's something I've been mulling over for a while. Koi girl Sakura gets herself into another naughty situation after breaking an ancient rule. Just desserts, amirite?


Sakura darted through the water this way and that, relishing in the feeling of the cool liquid against her nude, scaled body. As a koi, a swim in her wealthy family's private lake was the perfect activity for a late summer afternoon. What's more, her parents rarely visited the area since they were always busy with work, allowing the fish girl to do whatever she wished. Without the threat of a random passersby spotting her and her traditional, conservative parents out of the picture, she could easily satisfy her feral instincts and sexual kinks with her favorite hobby: skinny dipping.

As a daughter of a rich family, she happened to be quite vain, and for good reason; she was a very attractive fish. Her wet, redish-pink scales reflected the sun's rays into a beautiful pattern and her lithe body almost danced as she swam through the water. Her soft face, modest chest, and sizable hips gave her a cute appearance which only made her even more desirable. The only issue was that she was socially inept and completely introverted, else she would have had multiple men pussy-whipped at this point.

So here she was, alone and naked in the middle of the lake and perfectly content with herself as she wasted away the rest of her summer vacation. She swam laps, danced, and lazily floated in the lake's natural currents. However, during one of her elaborate routines, she accidentally wandered into what her parents called the forbidden area of the lake. She didn't know why it was forbidden and she believed her parents didn't either, as they were told so by their parents and their parents. It was a long-standing tradition spanning many generations of never approaching this area and know one alive knew why.

Being the bratty girl that she was, she decided to break yet another rule behind her parents' backs. She made her way deeper into the untouched waters, keeping her eyes open for any reason why her family was so scared. She swam for a good half-hour before she started growing bored. She went to turn back, but as soon as she thought of leaving, a strange feeling appeared in the back of her mind. Her diminutive scales bristled, but seeing nothing around her, she told herself that it must have been that usual guilty feeling of doing something naughty. She blocked it out and began her journey back to familiar waters.

Suddenly, a strange object shot out from a shadowed area and wrapped itself around her ankle. Another one came flying out a moment after, binding a wrist. Wide eyed and terrified, Sakura fought against her constraints, using her powerful tail to generate as much thrust as she could while using her free limbs to twist and turn in the water. The tentacles, as she saw them, started to loosen and she felt herself slowly free herself, but before she could make her escape, several more of those boneless limbs grabbed her, binding her remaining limbs and tail as well as her torso. She was forced into a position similar to being on her hands and knees with every sexual implication thereof.

Sakura was pulled closer to the darkness as more tentacles lazily approached her. One of them wrapped itself around her neck, not to choke her but to display dominance. Its end floated under her chin and made a wide, vertical U as its tip kissed her lips. Without warning, it began shoving itself into her mouth. Sakura didn't react in time and the extremity entered her without much issue. The koi bit the tentacle as hard as she could, but its rubbery skin was too thick and strong to penetrate. As she fought, she started tasting a sweet sap. Correctly assuming that it was coming from the invader, she tried he best to spit it out.

Swallow, a dark voice emanated from the back of her head. Sakura was terrified of the sound and looked around for its source, but all she could see were the countless tentacles floating around her. Swallow, it said again, this time with a little more aggression, and the tentacle around her neck began rubbing her throat, similar to how one would force feed their dog a pill. Between the overwhelming flow of sap and the massage, the viscous fluid began running down her esophagus. With no other recourse, Sakura submitted to the creature's demands and began swallowing.

Immediately, her will to fight her captor died away and her wish to escape was buried beneath artificial contentment. Her body became weak and malleable and other than a few subconscious twitches, Sakura was helpless in the grip of the monster. Good girl, the creature purred in her head. Its tentacles loosened their grip to more of a loving embrace. Her limbs were still bound and her neck was still collared, but the discomfort ceased. It has been so long since a mortal made their way into my waters, and a female no less. I feel inclined to reward such ignorance.

Sakura tried to speak, to ask the creature what it wanted with her, but the tentacle in her mouth made it impossible. The intruder reacted by pushing itself down her throat, its sap neutralizing her gag reflex. She didn't need her airways to breathe, instead using the gills on her neck, but the sudden intrusion had her shudder with discomfort. I do not like when my toys speak. I advise you to stay silent and obey. Sakura whined but complied with its demands.

Two new tentacles slithered through the water and along the koi's legs, stopping just before her prostrate behind. Now, I forget. Which hole is used for mating? the entity asked itself. With a mental shrug that the girl could almost see, it pushed its extremities against both of Sakura's vagina and anus. The vaginal intruder easily penetrated her and filled her birth canal while the other struggled to gain entry. With some metaphorical elbow grease and a healthy amount of sap, the appendage forced itself passed her anus and deep within her rectum.

Sakura shrieked and began futilely struggling against her constraints as the appendage made it's way deeper and deeper. She could sense amusement over the mental link with the creature. It must've been a couple feet deep within her body before it stopped. Sakura felt bloated with it wriggling inside of her, but soon enough, the sedative-like sap the tentacle produced quickly absorbed through her insides and calmed her down.

When the koi again displayed compliance, the tentacle in her vagina slowly dragged itself out of her until just the blunt tip remained, then pushed itself back in until it touched her cervix. The creature began fucking her, starting slow to get her attention before ramping up to a higher speed. It used their mental connection to gauge her pleasure and deduced the best speed to maximize the fish's pleasure. Despite the circumstances, Sakura began enjoying the molestation. It wasn't her first time being coerced into sex and even though her "mate" was a monster hidden in the shadows, her delinquent sexuality rose to the surface.

As the tentacle in her cunt fucked her like a jackhammer, the one in her ass also started to oscillate as well, using much broader motions and effectively using its sap as a substitute lubricant. Sakura was both in shock and bliss, unable to function as her body was wracked with pleasure. Despite being an anal virgin, the rectal stimulation grew on her and the shearing motions between her holes stimulated her nerves in new ways. Sakura moaned like a bitch in heat, the tentacle blocking her throat making it sound more like a purr.

Sakura's body writhed within her constraints as she neared her orgasm. As the burning in her loins intensified, the speed at which the entity fucked her increased. The koi nearly screamed, or as close as she could while gagged, when she hit her climax. Waves of extraordinary pleasure wracked her body as she came, causing her body to lock up. The tentacles continued their motions throughout her orgasm, further exaggerating the bliss and causing her mind to go blank.

When her orgasm subsided, the tentacles stopped their motions. Sakura thought that she would be released, but then the appendages started pulsing. After the first two or three squirms, Sakura felt something viscous and warm, more so than the sedatives she was force-fed, get pumped into her body. She watched enough hentai to know what was going on, but she was too weak from the sap and orgasm to do anything about it. She floated motionlessly as the creature pumped both her vagina and rectum full of its seed.

Her cunt was overfilled after the first few spurts and the semen leaked out of her pussy in bursts. Meanwhile, her innards were flooded with cum and her belly inflated like a balloon. She was luckily spared the same treatment on the other end, and when the creature was finished impregnating her, it slowly removed its extremities from her. As it disappeared back into the shadows, the mental link between the two slowly ceased. You will be the mother of my spawn. Go, and spread my kin across the land, it said before disappearing from her mind. When the connection finally broke, exhaustion took over and the fish blacked out.

When Sakura awoke, she was laying on a beach near her residence. She slowly pushed herself onto her hands and knees and as she did, she could hear and feel semen pouring from beneath her tail like a waterfall. Her belly wasn't as big as before and looking behind her, she saw a long pool of cum from the lake to where she had laid. Her thighs and tail were caked in the stuff and streamers of the virile liquid hung near her groin. The koi struggled to her feet, gravity further emptying her.

She stumbled to the water and carefully washed herself off, giving her body time to naturally expel any excess fluids. When she was decent, she made her way back to where she left her clothes. As she walked, a thought came to her and a toothy grin spread across her face. It'd be so pissed if it found out I'm on the pill.
