Once you stepped into the monster’s match event, you didn’t know what was going to happen. You filled a very long quiz about your preferences, and you were a bit shy when you gave it to the monster on the front desk, your face flaming as you checked over your answers… tentacles being the big thing you were looking for after trying all tentacle dildos available in the market. That costed you a little fortune, and you wanted more… you needed more. You didn’t know why, but there was something inside of you that craved that. That craved to be so full of monster that you couldn’t think anymore. And then you saw the event… and you swallowed your embarrassment and signed up.
And there you were, nervous and excited, anticipation boiling inside your tummy and making the butterflies go crazy. You were more than ready to be debauched by a tentacle monster, hopefully.
“Follow me,” a naga with a clipboard said, pointing to her right. She took you down a corridor framed by doors at either side. “It said you didn’t care if the monster could speak your language, is that right?” You nodded. “And you also didn’t mind the gender of your monster, correct?” You nodded again. She checked something over her clipboard and opened a door to her right. You gasped as she said: “This is Al… enjoy?” The naga said, chuckling a little as she moved away, leaving you staring at the biggest monster you’ve ever seen.
The monster did something akin to a chirp, you couldn’t understand any of it but it felt like a greeting, so you raised your hand in a salute. Their big mouth with teeth as sharp as knives opened in a smile, and you shivered, but then the rest of his body moved and you could see the dozens of tentacles dancing around, and your insides clenched. Your body tensed in anticipation as you approached the monster in front of you.
They reached to you carefully, a slimy tentacle touching your hand. You took it, squeezing it in reassurance that you wanted to be there, you craved to be there, to be touched by those tentacles, to be fucked until you couldn’t walk.
And that’s all the signal they needed.
Their tentacles embraced your body as you squirmed a bit, trying to get comfortable over the giant monster under you. It was so much and not at all at the same time, you needed more but didn’t know how to ask for it. The tentacle monster under you was smiling in almost a creepy way, but it only made you feel more aroused, the edge of danger making you as horny as ever.
In a blink, you were naked, and there were tentacles all over your soft skin, caressing and touching, probing and pinching until you were squirming and your pussy was getting wet.
A tentacle teased your asshole, and you were more than glad you prepped before arriving, your asshole already stretched and ready to be fucked into next week. The monster seemed to appreciate it, too, grunting as the tentacle pushed inside slowly, the suckers all over your body adding pressure. You knew you’d be all marked up the next day, and that only made your pussy wetter, clenching over emptiness and making you whimper.
You wanted to scream at them to take you already, to fuck your pussy so deep you could feel them against your cervix. But they didn’t. They only fucked your asshole slowly, the rest of the tentacles caressing your body and sucking everywhere they could. It was exhilarating and wild, and you felt like you were about to burst at any second.
But then another tentacle found your open mouth, gaping in pleasure, and slowly parted your lips, caressing the inside of your cheeks, latching the suckers to your tongue in something akin to a kiss that made you groan around it, your lips closing over it and making the big monster rumble under you.
You sucked hard, and the monster stopped moving, as if you surprised them. You did it again, and the tentacle in your asshole started moving faster, the tip wriggling inside of you and sending a cascade of fluttery sensations down your spine. You tried to scream, but the monster only takes the opportunity to slip the tentacle further down your throat, making you gag a little as you sucked around it.
You felt overwhelmed in the best way possible.
But you still felt so empty with your pussy dripping and empty. You rolled your hips, asking for more, wanting more… And then you felt it. The tip of the biggest tentacle pressing against your warm opening. You moaned, and the monster purred under you. It was so close to fucking your pussy… So close….
You didn’t get a warning before the tentacle pushed deep inside your welcoming heat, tickling your cervix and starting a fast pace that had you moaning and gagging, your body under their control as the rest of the tentacles held you and moved you like a doll. The tentacles fucking every one of your holes plus the ones sucking and pulling at every sensitive place of your body were driving you insane.
There were tentacles everywhere, sucking on your nipples, latching to your clit, fucking every one of your holes as they moved you around… It was everything you desired and more.
You came. And they didn’t stop. They kept fucking you until you were propelled over the edge again. And again. And again. So many times you couldn’t keep count, and you still craved more. It was like the tentacles unlocked something more inside of you. It was too much, but you couldn’t get enough. You were spiraling into a pleasure you never knew existed…
And then everything exploded into a thousand stars behind your closed eyelids as pleasure ripped through your body and made you scream around the tentacle buried down your throat. It was even better than the orgasms you had before, bigger and stronger in a way you didn’t even know could be possible. It was like your whole body changed around the tentacles holding and fucking your body. It was earth-shattering, it was just… indescribable and better than you could ever imagine.
The monster grunted, a low vibration that drove you further into pleasure as you felt warm release filling your holes, washing over your body as every tentacle around you released a clear warm substance that tingled your skin and made you more sensitive to touch. You screamed as the tentacle in your mouth pulled back, your voice getting hoarse as wave after wave of heat ran down your body, your breathing erratic and your lower holes clenching over the tentacles still filling your insides.
You closed your eyes for a second, your brain going blank as your body seized with pleasure. By the time you came back down, you were still stuffed, but the tentacles weren’t moving anymore, only caressing your gross skin, covered in fluids.
You were trying to get your breathing under control when you heard it. “You were perfect, my mate,” the voice sounded inside your brain and you let out a screech.
“You… You just talked inside my head,” you let out with a manic laugh, still a bit breathless and sore all over.
“A communication only reserved to true mates, my love, my lovely human…” They said, their tentacles once again caressing your bruised skin. You shivered when more tentacles joined, probing your tender holes again. “Do you need more? Do you crave me as I crave you, my mate?”
You could only nod as the tentacles pushed inside of you once again and your brain melted in pleasure.
