The Hero Became a Succubus, and the Only Way to Level is to… What?!

The room was large enough that Kanae could fly around in it. Tentacles chased her all over the place. There had to be at least twenty ropers in total. She flourished her whip to try and thin their numbers, but their appendages came together as a sort of cushion to protect each other. When Kanae activated the Collar of Domination to seize control of one roper, the rest dogpiled it until there was little the monster could do.

A tentacle snatched Kanae by the ankle and yanked her to the ground. She rubbed the back of her aching head, then glanced up. The many ropers fired their tentacles, restraining her and keeping her from flying away.

"Oh, no… I just want to find my— mmph!" Kanae choked on a tentacle worming into her mouth.

They ripped her clothes off until she was bare naked and took her whip. Kanae had tentacles pulling her limbs taut by the wrists and ankles. She could have taken these monsters if there were a few. However, twenty ropers amounted to over a hundred tentacles to contend with. There was little to do other than to let them have their way with her.

As monsters, their instincts to fight were great but their intelligence was extremely low. These things didn't know they were dealing with a succubus. Kanae only needed to let nature take its course. So, she switched on Masochist and allowed the ropers to have at her.

A tentacle plunged into Kanae's pussy, and another drilled into her ass. She squeezed her eyes shut as they mercilessly pumped both holes. The impatient ones practically mummified Kanae with tentacles. Their slimy and slightly warm appendages wrapped around her wherever possible.

Kanae panted heavily as she sucked on the one like a cock in her mouth. Two other tentacles flicked at her stiff nipples, sending waves of tingly pleasure through her. She grabbed stray feelers to jerk them off. Soon, the one in her mouth throbbed and shot a thick load down her throat, and she gladly drank it all up.

"Mmmh… Mmpph! Fuck me harder! More! Keep using me!" Kanae pleaded after the tentacle pulled out, only for another to take its place.

The roper she had sucked off teetered back and forth until finally falling unconscious. Its large one eye spun in circles. One after another, Kanae felled the tentacle monsters by draining them for all they had. Before long, they were all lying on the ground, their feelers limp and twitching, and eyes shut or spinning. She was on the floor with them, still covered in tentacles and leaking from every hole with their seed.

"Ughh…" Kanae gulped down a mouthful of roper cum and switched off Masochist before getting up. "That took a while… but I lived."

[Skill Drain has temporarily acquired the skill Grow Tentacles.

None of them were getting up any time soon. Now the real question was… where was the exit?

Kanae had to push slumbering roper bodies around to find her Matron's Regalia and Lust. They were buried underneath a pile of entangled tentacles. The outfit was also covered in ejaculate from all the leaking feelers. Well, at least she was used to being covered in it.

Now that the ropers were sideways on the floor, a quick look around yielded something Kanae didn't notice before. Or maybe it was so because the ropers had been defeated. At the far end of the room were two swirling vortices on top of their own runic circle. They looked big enough for her to stand on.

"I wish I had some kind of diving spell to know what these do." Kanae sighed.

Left or right. Not wanting to waste any more time, she stepped into the right vortex. A vacuum of air sucked her in, and Kanae appeared in another room. The walls were made of newer sandstone, still a bright tan rather than a dull gray like the other one with ropers in it. But it didn't look like she would be resting any time soon.

A dozen wild minotaurs in the middle of eating some kind of boar from a fire pit stopped and stared at her. The meat between their legs rose to full mast.

"Not this time!" Kanae casted a Mass Charm on the room.

All twelve bulls stopped before they could stampede. Kanae walked past them without fear of being made into a cock sleeve. She picked up a roasted leg of a boar from the fire to eat while searching the room for an exit. Just like the roper room, there were two magic circles at the very end. The runes carved into the sandstone bricks weren't lit. There weren't any vortices either. Was there a condition she needed to fulfill?

It didn't take Kanae much thinking. The Necro Lord of this place probably designed it so that the inhabiting creatures needed to be defeated. She could make them fight each other… but that was no fun.

"I have a feeling you all want to fuck me. Isn't that right, big guy?" Kanae pulled the waistcloth away from one minotaur and stroked his enormous shaft. That heat radiating from this thick cut of meat was enough to make her sweat in the nether regions, causing the roper ejaculate to gush right out. It was as if her pussy was making room for a more delicious treat.

Minotaurs had become a favorite of Kanae's ever since her friend Ichi had turned into one coming to this world, as well as Master Marwin often commandeering a body to use. After all, who wouldn't appreciate a strong, virile bull? Rather, bulls, since there were so many of them.

Kanae dropped the effect of Charm, but they weren't immediately aggressive. The minotaurs knew now they were dealing with a powerful succubus. With a simple command, most succubi would have ordered them to hurt each other for enjoyment. Fortunately for them, she wasn't most succubi.

"Who wants to breed me first?" Kanae asked.

Two at a time, the minotaurs took turns spit roasting her. Thankfully, not over the fire. With a cock hammering into her pussy and another throat-fucking her, Kanae was in ecstasy. When a greedy minotaur wanted her all for himself, his one hand was large enough to hold her entire waist and use her like a cock sleeve. He pumped harder and harder as if trying to impregnate her.

Slap! Slap! Slap! Slap! Slap! Slap! Slap! Slap!

"Ooouughh! I'm going crazy on your cock! It's going so deep… punching the entrance of my womb! Aaaaahhhhh!" Kanae climaxed so hard that she squirted.

The same minotaur wrenched her off his dick, then buried his snout into her mouth. A thick tongue lapped at her cum-filled cunt and gulped down her waterworks. Kanae came again from his cunnilingus. Her hands found purchase on the minotaur's horns.

After satiating his thirst, he tossed Kanae to the ground, where three minotaurs butted heads over who to go next. Still trembling from the recent orgasm, she pushed herself up by the elbows.

"Don't fight… hehe… take me all at once…Kanae lifted her leg to reveal a gaping cunt freshly licked clean, a twitching asshole in need of filling, and an open maw that was her tail-pussy.

By the time the minotaurs were done, Kanae was entirely covered in their spunk. Every hole was gushing with their seed. She was lying on top of an unconscious minotaur whose dick was still plugged deep inside her.

In the distance, the two magic circles had activated and their vortices awaited to be entered. Kanae tried to get off the minotaur, but her pussy was too fastened to his dick. She grabbed the nose ring and put all her strength into pulling.

Pop!

Kanae separated from the minotaur's dick at last and rolled off. She didn't bother putting her clothes back on. Instead, she grabbed the regalia and whip, then made for a vortex at random. Her body painted the floor white on the way there. Still on all fours, she crawled into the left vortex, emerging in a dimly-lit room with only torches on the sides of the wall. This place had a much taller ceiling than the past two. Leaving a trail of minotaur cum in her wake, Kanae wandered deeper in until a pair of red eyes peered at her from the dark.

Chains rattled, a rumbling growl made the room vibrate, and each step it took was a heavy footfall. Kanae backed away as the hulking monstrosity approached her. The torchlight illuminated the head of a maneless lion first, the body and arms of a troll, the legs of a dragon, and finally the tail which was a hissing snake. This creature was five times her size. She should be afraid, but her eyes were drawn to the two-pronged, throbbing red cocks between its legs.

"Alright, I know the drill." Kanae tossed her belongings away, wiped the drool from her lips, and turned around with her ass in the air. "Come and get me!"

The chimera pounced on Kanae. Its two dicks found resistance against her ass and pussy. But lubricated by slippery ejaculate and pried open from constant use by the minotaurs, this vicious beast forced his way into both of her holes.

"Oh, fuck, fuck, FUCK! IT'S TOO BIG! I'M GOING TO BREAK—" Kanae switched on Masochist in panic. "YES, YES, YES! MESS ME UP WITH YOUR COCKS!"

The size of the chimera dicks rearranged Kanae's insides. Face pressed to the ground and drooling, she had become delirious from the intense mating. Their hips clapped with incredible force. Each thrust was as though a massive hand repeatedly came down to slap her cheeks. He hammered so hard, it constantly knocked her lights out.

PLAP! PLAP! PLAP! PLAP! PLAP! PLAP!

"My stomach… it… aahhh! You're inside… my womb… you pushed into my womb!" Kanae cried.

Its serpent tail suddenly lowered into her field of vision. The snake hissed once before sinking two sharp fangs into her shoulder. An extreme wave of euphoria washed over Kanae. Was that… an aphrodisiac? She saw love in being fucked so roughly. Heart, mind, and soul recognized the chimera as its beloved mate. 

"Mmm! Nnh… aahhh! Ooohh! Chimeras are… created, right? I bet… ahh! You must be lonely… without a mate… I'll be your bitch! I'll be your chimera bitch— aaaahhhh!" Kanae climaxed over and over again. Her trembling ass and pussy massaged the chimera to an orgasm. Hot monster emptied its balls right into her womb. In the backdoor, however, it painted her ass white. The chimera's load exploded with so much pressure, the geyser of cum sent Kanae flying across the room into a vortex. She rolled to a stop at the start of a long corridor and groaned.

[Skill Drain has temporarily acquired the skill Mating Venom.

Mating Venom: Due to chimeras' violent tendencies, the male and females tend to spar before mating. If a female injects its venom first, they will put the male to sleep, perform intercourse until inseminated, and then escape. If a male injects its venom first, the female will go into a state of extreme libido and allow herself to be mated with.]

Its sheer volume of cum had inflated Kanae's womb and belly as if she were pregnant. She rested with her back on the cold floor, hands over her abdomen to try and push all the spunk out. Ejaculate gushed out of her in thick spurts. She switched off Masochist and sighed.

"Uuh… I'm so… full…" Kanae burped.

During the past three sexcapades, she managed to obtain a skill from each of the creatures. First, Grow Tentacles. Kanae lifted an arm, willing a tentacle to grow from the shoulder region. It looked just like what the ropers used to fuck her with. Next was Minotaur Might.

Kanae clenched and unclenched her fists, but she didn't feel any stronger. There was also no way of testing it without getting into a fight. Last was Mating Venom. What a weird name for a skill. Kanae searched all over her cum-drenched body and couldn't find where the venom would come from. It wasn't until she rubbed her cheek did she realize the venom came from her teeth. The lateral incisors to be precise. She spat the purplish venom into her palm.

"Wait… my stuff!" Kanae whipped around, but the magic circle was inert. She wasn't getting back into the chimera room. Luckily, the powers of the Matron's Regalia were still available to her. But not having Lust in her hand was a problem.

If there was no going back, forward it was then. As long as Kanae could find the Necro Lord and defeat him, she could get everything back and find the others. Hopefully.

After spending a few moments catching her breath, Kanae was able to walk again. Her ass and pussy were still aching fiercely with the desire to be stuffed again. She stumbled naked and covered in spunk to the door at the end of the corridor. It was her only way forward. A placard above the door read, 'OBSERVATION DECK' and another beneath it warned, "DO NOT ENTER'.

Kanae channeled her inner-Edina and entered anyway. She opened the door quietly and slipped into a beige-marble room. There was a large humanoid at the very back, in front of a series of crystals arranged on a candelabra with many branches. To her left, a large astrolabe with varying-sized spheres rotated slowly. To her right was a study, furnished with enormous bookshelves, a desk, and a bed.

"Where?" the creature at the front growled. "Where did that succubus go? I can't find her anywhere! This isn't good… Why do I keep losing track of adventurers?! Lord Charron won't be happy with—"

"Ahem! Looking for me?" Kanae asked.

He spun around, and they both gasped for different reasons. Him, because he didn't expect Kanae to be here. Her, because the figure looked nothing like a Necro Lord. Tall and imposing, she could tell even with his dusty gray robe on that he had a lot of muscle under there. His face was that of a horse. He had fine brown fur with specks of gray dotting his coat. An almost comically tiny pair of glasses rested on his face.

"How… How did you get in here? And why are you naked?" he asked, adjusting the spectacles to get a better look.

"Why am I… because of your gauntlet of rapey monsters! Tell me, are you the Necro Lord of Tomb #3?" Kanae asked.

"Indeed, I am. My name is Necro Lord Thored. The 'e' is silent. What you traversed just earlier wasn't a gauntlet. They were cages where I keep my dungeon monsters. To think… you defeated them all, including the chimera, with your succubus wiles… I won't be able to make use of them until they awaken! No matter. My Appraisal Eye tells me you're a Seductress. Your Versatile Womb shall aid in propagating monsters for me—"

When Thored reached for the staff leaning against the table, he accidentally knocked it away. The horseman fumbled after it like a goof. Kanae seized the opportunity to tackle him. Her strength, made stronger by Minotaur Might, lifted him into the air.

"Ow! Unhand me! Unlike your perverted race, I'm not into being stained by other creatures' reproductive excretions!" Thored exclaimed.

Kanae eyed the bed. She hurled him over. The legs of the frame cracked when Thored landed. Before he could get up, she landed right on top of his waist.

"I'm still horny from the Mating Venom your chimera injected me with. You will have to do!" Kanae bit into Thored's shoulder, injecting him with the same purplish spittle.

"I feel… strange… tingly… oddly aroused? What did you do?" Thored gasped.

"Let's see what you're packing!" She ripped off his robes, revealing a thick cock standing at attention that made her eyes go wide.

The tip of Thored's lighthouse was flared out. It was already leaking with precum. Kanae saw red. She wanted that thing inside her a minute ago.

"Wait, wait, wait, wait, wait! It won't fit! Are you crazy?" Thored cried.

"Won't fit? Didn't you watch me take your chimera's dick." Kanae got on top and sat down on it until they were connected at the hips.

Thored attempted to incant a spell. As the words left his mouth, Kanae shoved a tentacle in to keep him from uttering the final part of the incantation. She sprouted more tentacles to restrain his limbs like the ropers had done to her. Although the beastman was all muscle, he couldn't so much as budge against Kanae's strength thanks to Minotaur Might.

Slap. Slap. Slap. Slap.

"Oooh… I haven't had sex in a while, and with a succubus, this is…"

Plap! Plap! Plap! Plap! Plap! Plap!

Kanae picked up speed, slamming her hips against Thored with more power. Minotaur Might made it so that each successive hit was stronger than the next. The bed went from creaking to cracking to snapping as the wooden frame folded under them.

"I take it back! Please, stop! It was nice at the start, now it's beginning to hurt! My hips! You're going to break my hips!" Thored shouted.

Crrck!

Kanae came at the same time something in Thored shattered. His head went limp to one side and foamed from the mouth. The thick cock buried inside her pussy spurted a big load that filled her up.

[Congratulations! You are now level 255!]

Exhausted, Kanae laid down on Thored's broad muscular chest. Her whole body was twitching unceasingly after having so much sex. But if she had gained experience, then he must have been at a very high level. Higher than even her. 

The effects of Mating Venom were finally wearing off. Kanae tried to get up, but her legs gave out.

"Maybe… a little post-coitus nap… is in order…" Kanae shut her eyes and drifted off to sleep.
