Chapter Text
You walked along the dirt path to the lake, having decided to take a swim that day. You knew well about this enchanted lake, but no one else did as far as you knew. You had been there several times before, the first time was strange, but you knew you didn't want it to be your last. Luckily, it was secluded enough for you to enjoy it by yourself.
You made it to the lake, setting your towel down on the grass and undressing. You never brought a swimsuit, you only skinny-dipped in this lake. You stepped into the warm water, the level slowly rising as you went in deeper. You swam out to the one edge of the lake where you knew there was a land shelf for you to sit on and relax. You leaned your shoulders on the grassy side behind you, waiting patiently.
What made this lake enchanted was its secret, your dirty little secret as to why you always chose to swim here. A creature lived in this lake, you had never seen the full body of it, just its appendages. Slowly, you saw them rising up to you from deep below the water. Green, glimmering tentacles softly brushed against your skin, coyly trying to get your attention. "Hello," you chuckled. "It's me again."
The tentacles remembered you, one coiling around your ankle. Another tentacle slid up your side, wrapping itself around you, just beneath your breasts. "You're not shy today," you giggled. They were so cute, and you loved coming here to spend time with them. A tentacle traveled lower than the last, making you jump with surprise as it wrapped around your upper thigh. That one and the tentacle around your ankle tried to gently pull your legs apart.
"Asking nicely?" you teased, spreading your legs for them. "You know you always have my permission." You had gotten wet just walking to the lake, you couldn't help yourself just thinking about being treated like this. You knew you couldn't come to the lake too often, not without it looking suspicious. You decided to only come here once or twice a week. No one knew about your secret hideaway, and you wanted to keep it that way.
The tentacle around your waist suddenly moved, squeezing and massaging your breasts. You let out a few soft moans as you relaxed, letting the tentacles do what they wanted with you. The tentacle that had wrapped around your thigh caressed you warmly, moving up and down your leg, getting closer to your wet pussy with each stroke of your skin. More tentacles appeared from the water, wrapping around your ankles. Two even reached up high out of the water to hold your wrists above your head.
"So that's how you want it today?" you asked, a sultry tone in your voice. "Fine, be that way."
The tentacle playing with your tits used its suction cups on your pert nipples, making you shut your eyes and moan softly as it sucked and squeezed your rosy peaks. One tentacle grabbed your other thigh, gripping it firmly and helping the other spread them open. "Mmm," you moaned, throwing your head back. "Yes~"
You gasped once you opened your eyes, seeing a long, thick tentacle creeping up from below the water. You chuckled, grinning deviously. I swear, you thought, it gets bigger every time. The thick tentacle lightly ran up one of your legs. Damn, the way it tickled your skin felt good. "Ohh," you moaned lowly, relishing in the way it touched you. "Go on," you whispered, watching it get closer to your pussy. "You can do whatever you like."
It gently rubbed against your thighs, occasionally grabbing you with its suckers and leaving small marks on your skin. It finally stopped teasing, running its tip up your slit. You gasped at the sudden sensation, relaxing into what the tentacles wanted. "Please," you begged. The large tentacle only teased you lightly, playing with your lips and running its suction cups over your clit. "C'mon," you groaned in frustration. "Just fuck me, already!"
A smaller tentacle came out of nowhere, maybe you just hadn't been paying attention to it. It began softly rubbing your clit as the larger tentacle slowly penetrated your hole. You let out a cry of painful pleasure, your eyes rolling into the back of your head. You had to be right about it getting bigger each time. Luckily, you had been horny all morning just thinking about the tentacles, so you were loose enough for it to actually fit inside of you.
You tried sitting up so that you were more on top of the tentacle than the shelf of land you were using for a seat. As you did, your body slid further down onto the tentacle, getting it even deeper inside of you. "Fuck!" you whined, adjusting to the tentacle's size. You gave an experimental buck of your hips to see if you were comfortable enough to keep moving. It felt insanely deep, but not too painful.
You slowly began bouncing up and down on this tentacle as it thrusted itself inside your tight cunt. The girth alone was stretching you out, but it felt too good to stop. The other tentacles still toyed with you, playing with your tits, rubbing all over your body, one even caressed your ass while giving you a bit of help with riding the larger one. It felt amazing to have so much attention given to your needs.
The tentacle you were riding pushed itself in even deeper, making you scream. You couldn't believe how deep inside of you it was, it felt like the tip of it was poking the bottom of your stomach. You only kept bouncing up and down on this massive tentacle, still being held with your arms above your head. You felt so vulnerable, completely naked and unable to do anything about the tentacles that were fucking you, and damn were you enjoying it.
The tentacle supporting your ass began squeezing, grabbing your ass as if it craved you. Another tentacle helped it pull your cheeks apart, a smaller one gently playing with your asshole before penetrating it. Your mind shattered in ecstasy. You were about to scream when a tentacle burst out of the water, covering your mouth. Every time, you thought. The tentacles always make you feel so good you can't control the noises you make. So they cover your mouth to maintain your secret.
Of course, covering your mouth tempts them to stick their tentacles down your throat, effectively fucking you in every hole at once. Your mind fluttered being used like this. The sensation of every hole filled, being used and played with was just such a turn on for you. You bucked your hips harder, wanting the thick tentacle to be rough with you. It understood what you wanted, and began pumping itself in and out of you fiercely.
You screamed against the tentacle that was down your throat, crying out over and over again as your tight little wet pussy got stretched out by such a big tentacle. Your clit, still being stimulated by a small tentacle, was beginning to burn with sensitivity. You shook your head, unable to speak with the tentacle down your throat. It caught on that you wanted it to stop, slowing down before pulling away.
The large tentacle pulled out of you, making you groan from the sudden emptiness. "No," you whined. "Not you." It understood, happily thrusting back inside of you with a sloshing noise. You grunted against it entering you again, but this time your limbs were free. You wrapped your legs around it, pulling it deeper into you. The tentacle hooked for you to ride it while holding onto it. Your arms and legs wrapped around it, still sitting on its end and riding it.
The friction between you and the tentacle intensified as it rubbed its suckers against your clit, bringing you closer to orgasm. Plus, the large tentacle inside of you had started to thrust against that sweet spot deep inside of you. "Oh fuck," your voice reached a higher pitch. "Fuck! I'm gonna-!" A tentacle burst out of the water, covering your mouth before you could shout. You screamed as you came onto the huge tentacle, your juices gushing out of you as it still pumped in and out of your cunt violently before slowing down as you came off your high.
Your body weakened as you finished, collapsing onto the hooked side of the tentacle. It gently carried you to the shore, setting you down on the towel you had laid out. It retreated back into the water, leaving you feeling satisfied.
Once you regained your composure, you dried yourself off before getting dressed. Just before you left the lake, you looked back to say goodbye. To your surprise, the tentacle was still sticking out of the water. It waved at you as it saw you getting up. You chuckled, thinking how cute it was. "I'll see you later," you waved back at it, blowing it a kiss before skipping on your way back home, a smile on your face.
