A good girl at the seaside

Sea-monster x fem!reader || tentacles, praise kink, forced orgasm, overstimulation

You were floating on the beach, still not believing your luck. A weird lady at the inn recommended you the most precious little beach and there was nobody around, it was completely deserted. You spent some time at the shore, basking under the sun with your bikini on, before you said fuck it, and chose to take off your bikini completely. The sun felt marvelous against your naked skin, and not having any tan lines was also a pro. You didn't want to get caught, but deep down you felt a spark of heat at the thought of someone observing your naked form. Someplace inside of you, there was an exhibitionist wanting to come out.

Floating in the water felt like a warm caress against your overheated skin, the sea salt making your body tickle, and your nakedness making you feel naughty. After a while, you felt your fingers pruning. You got back to the sand, laying down flat on your towel, the sun tickling your back and warming your skin. It was wonderful.

"What do we have here? A pretty human gift?" A raspy voice said from behind you. You screamed and tried to turn around.

"What the-?" You didn't finish that thought. A slimy something pressed at your lower back, pushing your body down and stopping you from turning to see who it was. Was that a tentacle? It felt like it. What the fuck. "Let me go!" You tried to scratch the tentacle, push it away from you, but more joined the first one, ascending the back of your thighs, sending shivers up your spine. Some grabbed your arms and pinned them down. Another pair grabbed your ankles and pushed your legs apart. You were completely exposed and trapped under some talkative tentacle monster.

"What a pretty pussy... We are going to have fun, aren't we?" The creature behind you said, a tentacle following a path to your center. You shivered involuntarily.

"What? No!" You tried to break free and turn around, but it was fruitless. The tentacles holding you down were way too heavy, had too much force for you to move.

"Hmm?" He made a sound of utter confusion. "You don't want to? But the lady said she sent me a present. And you are in my beach…"

"What are you talking about?! I don't even know who you are! What you are!" You screamed over your shoulder, still pinned to the ground, your breathing irregular with exertion of trying to get free. You tried really hard to bury the shiver of anticipation under your skin, the wetness pooling at your pussy… The slimy feeling of his tentacles against your heated skin felt wonderful, but you knew you didn’t want it. Right?

"Oh, my bad." His voice sounded completely dejected, like you offended him with your rejection. He sounded sad, and you hated that it made your heart ache for him. He was trying to tentacle-fuck you without even asking first, you shouldn’t be feeling sorry for him… But yet, you felt it. The tentacles holding you down disappeared, and you turned around completely.

He was some kind of sea creature, his upper half looked humanoid, his features flat, but handsome in a weird way. His skin looked wet and shiny, super smooth, like a fish. But his lower body wasn't human, it was a mess of tentacles that looked octopus-like, suckers included. You felt more heat rising inside your body, pooling in your lower abdomen and making your body flush. You wanted to blame the scalding sun, but you knew that it wasn’t the reason. You felt things for tentacles. You were a sucker for them (pun intended). Your heat had nothing to do with the sun, and everything to so with the otherworldly creature in front of you.

He was turning away from you, approaching the water and taking those enticing tentacles with him. Fuck no. "Wait!" You screamed at him before he touched the water.

He turned around, his sad eyes confused again. "You said you didn't want me."

"I- I know." You tried to think of a fast answer. "I- I was wrong." Wrong? What the fuck was wrong with you, that was the real question there. He tried to grope you with his tentacles, he did grope you, and you? You were asking him to come back and do it with intent this time? Dang, you were a pervy human.

"I need to hear it." He told you, his eyes fixated on your face. You felt a spark of comfort knowing he would stop if you asked him to, he already did. And now, with your consent, you wanted him to do all kinds of crazy depraved things to your body. You wanted to experience what a good tentacle-fuck could feel like and not the fake experience you got from your tentacle dildo at home.

You knew you should be more concerned, maybe even more confused about the existence of sea monsters with tentacles and abs of steel… But at that moment you could only feel the heat of his gaze over your body, the still present slimy substance on your skin and the wetness dripping from your pussy. You were horny, as horny as you’d ever felt. And he was there, ready to fuck you if you asked.

"I want you." You whispered, embarrassed.

"Good girl." You moaned at his words, your inner sub melting with his praise. He approached you again, his body undulating and his tentacles rapidly reaching for you. But he didn’t touch you, not yet.

"Aren't you scared, pretty girl?" You shook your head. "You should." He sentenced, making you shiver at the danger in his voice. Dang, that was fucking hot. "You want all of me?" You nodded, lost in a breeze of lust. And then his tentacles touched you, all over. He held you down again, this time on your back. The heat inside of you felt like a raging flame.

He didn’t waste a second. His suckers met your clit and you felt an out of body experience. "You like that, pretty girl? You should see how beautiful you look right now. How pretty my tentacles look against your skin." His words were making you squirm, not used to receive so many compliments. But you couldn’t escape his assault on you, his tentacles holding you down, his suckers taking pleasure out of you without asking.

You came faster than ever, and he hadn’t even had to enter you. He only needed one tentacle and a clever sucker to make you into a mess, and you couldn’t be more grateful. He probed at your entrance, making you moan again as he pushed inside. Two of his tentacles reached your boobs and the suckers latched into your nipples, the sensation so overwhelming that you came again, screaming so loud he shoved a tentacle in your mouth.

“Be quiet, pretty girl. I don’t want others to come see my gift.” He told you as he pushed his tentacles further down your holes. The tentacle in your mouth touched the back of your throat, making you gag as he moaned over you. The on on your pussy touched your G-spot insistently, the sensation to rough and raw that you couldn’t stop the gushing juices you let out, coming again. “You cum so prettily, your pussy looks so pink and puffy around my tentacle… I bet you can do more. Can you do more, pretty girl?” You nodded fervently, wanting so bad to be good for him. To be a good girl.

He fucked your mouth and pussy in tandem, his tentacles touching you all over. After what you thought was the ten orgasms, he lowered his pace. You were panting, your body shivering, and tears running down your face as the assault on your sensitive areas. Your body felt like an exposed nerve.

"This is okay?" A tentacle probed your asshole, pushing inside slowly, breaching your unexplored hole carefully. You wanted to nod, but you weren’t sure you’d be able to move without orgasming again. He kept looking at your face analyzing your reactions, repeating whatever made your body shiver, your pussy quiver, your moans escape around his tentacles.

And suddenly all your holes were full, his figure looming over you as he moved his tentacles all over. Inside and out, he was touching every inch of your body.

"Take me further. Come on." His embrace tightened as he pushed harder and faster into your holes, your moans muffled by the tentacle down your throat. "Good girl." You felt completely controlled, cared and fucked out. All three at the same time. You asked for this, and you were mesmerized by the feel of his skin against yours. “One more.” You shook your head, you couldn’t get more, it hurt so good when he pushed inside, but you didn’t think you could do more. You cried around the tentacle in your mouth and he shushed you, wiping your tears with another tentacle. Gods, he was all over you. “Come on, pretty girl, one more and I’ll stop.” He kept fucking you through your turmoil, the pleasure and pain mixing in the most excruciating sensation you’d ever felt.

“Come on, come for me one more time.” And you came. You felt some fluid leaking out of his tentacles, covering you in a mass of slime, down your throat, up your cervix… You were stuffed full of slimy liquid as he screamed over you.

After all that you just had one clear thought: real-life tentacles were a lot better than silicone dildos.
