4.44 - Swapped X

Natalie was fucked.

And not even in the good way. Though, by all indicators, that would be happening soon. But for the moment, Natalie meant in how thoroughly she'd been compromised. How easily Ana had extracted those admissions from her. The complete and total embarrassment she'd made of herself, just because another girl had gotten up close and teased her.

How was she supposed to look Ana in the eye, now? She'd already been struggling to be normal around her, and now she'd been forced to explain just how badly she wanted the other girl to pin her down and fuck her senseless. And honestly, even Natalie hadn't known how much she did, until five minutes ago. She'd been trying to fight it, because what a shameful situation to be in, wanting to be fucked by her own cock.

There was one saving grace keeping Natalie from melting into a puddle: The bloodthirsty monsters trying to kill the two of them.

Continuing the pattern, the next room opened with combat. It was hard to be blushing and tripping over her feet while focused on survival. It was a good, if intense, palate cleanser. And Natalie knew it only delayed the inevitable. A brief distraction before the real shenanigans of the dungeon began again. Before ... whatever happened next, between her and Ana.

Hell, a second ago, Natalie had been ready to be pinned down without the intervention of the dungeon. For Ana to take her right there in the hallway. What had gotten into her? What had gotten into Ana? Seriously. The cool, aloof, academic she knew Ana as did not seem to fit with how she could just switch into another mode. One that would pin Natalie against a wall and force her to admit some of the most mortifying things that had ever come from her mouth.

And why was Natalie so weak to it? Why did it turn her on so much?

In short, Natalie was a mess, and very much appreciated the reprieve granted to her in the form of a vicious monster.

The second combat challenge of this bizarre series wasn't a swarm, but rather, a single strong opponent—which was, on paper, her and Ana's more preferred fight. But that didn't mean it was easier than the crystal spider swarm. The difficulty had been ramped up by several tiers, so despite them being better suited to single-target combat, they were pressed far harder. The [Animated Shard Knight] was a cyclone wielding a massive two-handed sword, and [Hunker Down] could only save Natalie once in a while—and she was lacking armor, and also still adjusting to Ana's new body.

By the time Natalie and Ana put the creature down, she was panting, bleeding, and had thankfully had her mind cleared from earlier embarrassments. She much appreciated the fight, considering that.

But it had been a real challenge, enough to make Natalie fear what the third combat room would be. Whether they could even handle it. They didn't have a healer on standby to save them from serious injuries.

For minor ones, though, they had the health potions from earlier. Natalie drank one, then used the cleaning solution to freshen up. She appreciated the slippery liquid's ability to clear away just about anything, bringing her back to a more presentable state—especially since the gruesomeness of dungeoneering had apparently been combined with lovemaking. It would be rather unpleasant to get into anything intimate while actively wounded.

Like usual, a loot chest clattered into the ground after the [Animated Shard Knight]'s defeat. After cleaning up and healing, she picked up the materializing monster core from the creature's now-disintegrated corpse, then headed over to see what they'd gotten. As always, she felt a mix of trepidation and excitement at what might be inside the chest. Sure, Natalie appreciated how their team seemed to receive much better loot than most teams, but the bizarre items that came out certainly caused problems for her heart—and occasionally, her sense of shame.

But this was a combat encounter, so thankfully—or maybe disappointingly?—nothing lewd came out. Instead, it was more of the stat potions from earlier.

"Potions that give permanent stat bonuses," Ana said, shaking her head. "And we're not getting just one of them, but multiple, now. It's unbelievable."

Natalie agreed. Before, they'd received a single potion that granted furor. This time, they'd gotten three more: two that boosted prowess, and one for tenacity.

"Guess it depends on how much of a boost it gives, but yeah," Natalie said. "It's basically a mini level-up." Gear could also improve stats, but there were only four equipment slots and two weapon slots—so there were hard limitations there. Potions, however, could simply be consumed, and the user would see permanent boosts forever.

"I figure it's roughly the same as a minor equipment boost," Natalie said. It would make sense if the wording was so similar because they gave similar effects. So, in a way, it was like having an extra level-two item equipped at all times. Put like that, she became even more incredulous at just how fantastic the items were. Maybe not their most immediately game-changing loot, but still pretty crazy.

"Only have four total now," Ana said. "One more and we could split them evenly."

"Challenges aren't over yet. This chest isn't over. Might get more." Natalie tucked the potions in with the health potions, which were stored in the coin bag they'd gotten in the first room. She handled them delicately since they had to be worth a fortune. How much so, she wasn't sure, but if a price was put on them, it would probably be enough to make her eyes water.

Having secured the vials of glass, Natalie closed and popped open the chest. A second bag of coins followed, this one just as heavy, but with more silver mixed into the bronze than the last. For a second time, Natalie found herself disbelieving at the sheer lucrativeness of dungeon delving—and especially her brand of dungeon delving. Even Ana, who as far as Natalie knew, was a minor noble or perhaps someone of even greater importance, was impressed at the sums they were drawing out. Though maybe that was just at the disproportionate payout compared to what they should be receiving. An academic interest. Ana hadn't ever seemed especially invested in their delving rewards in a financial sense, only how they could be used for their progression.

A third open-and-close of the chest revealed an empty bottom. Natalie could hardly be disappointed by three stat-boosters and a hefty coin payout, and a part of her was even relieved that they didn't have to deal with another fiasco item.

At the last distraction being handled, Natalie was forced to confront the looming event. The second lewd challenge, coming up shortly. The first had been to suck Ana's cock, and seeing how the theme seemed to be progressively more intense situations, Natalie needed to be ready for anything.

She swallowed. Her intuition told her it wouldn't be some slightly more lewd event. If using combat as a guide, the swarm had been easy, and the combat of this room had nearly been too much to handle. Following that pattern, it was likely time that Natalie would be getting what she'd begged Ana for.

Her own cock, inside her.

Oh, heavens. Was she ready for that?

4.45 - Swapped XI

"How did last challenge even make sense?" Natalie blurted out. The question had been on her mind, but other developing events had taken priority. With the two of them about to venture into the next—likely lewd—challenge, she found herself needing to ask.

"What do you mean?"

"It was literally just sucking your cock. How is that a challenge? Something worth rewarding? At least with Liz, she had needed to—" Natalie bit her lip to cut herself off, remembering that Liz had asked for her to be discreet about that event.

Ana, and the rest of the party, had seen the initial description of the rules, and the saddle device, though. "It required her not to climax," Ana finished for her. "So there was an aspect of imposed difficulty. A challenge in the more traditional sense."

"Exactly." Whereas the blowjob room—and the fact that Natalie referred to a dungeon challenge in that way kind of broke her brain—had just been for Natalie to get on her knees and pleasure Ana.

"I've been wondering about that too. The nature of your class," Ana said, sounding way too academically interested for both the topic at hand, and what was coming up. "If we consider a typical delver, their class urges them to become a better combatant—and that's what the dungeon does as well. Throws powerful monsters at them until they grow in skill and competence. If viewed under that light, then the dungeon offering a sex-based class any type of lewd challenge is reasonable, since the class-bearer would become more proficient in sex. An artificial constraint like Elizabeth's is unnecessary. I could liken it to how the dungeon often throws a simple monster at us, without any complicated scenario accompanying it. The goal is to make you grow in matters related to sex, perhaps by pushing boundaries or simply giving you opportunities to refine your skill set. So, it makes perfect sense."

Wow. Ana had actually thought about it, then. Natalie had mostly shrugged and dealt with the practical results of her class, but here was an explanation. Though it missed the why behind being given a class that urged her to 'grow in matters of sex'. It at least explained why the dungeon acted like it did, and also why the blowjob room had been so straightforward.

"Huh," Natalie said. "So, what's the end result? It wants to turn me into some complete degenerate?"

"Not necessarily. High-level delvers are hardly all violence-addicted sadists. They're simply very, very good at killing. Which I suppose means the dungeon wants you to be very, very good at fucking."

Natalie stared at her. "How do you do that?"

"Do what?"

"Say something so ridiculous with a straight face."

"Years of practice," Ana said coolly. "And, fascinating as I find this discussion, I do believe you're stalling. Didn't you promise me I'd get to put this thing inside you?" She grabbed her cock and wiggled it at Natalie. "I'm getting impatient."

Natalie's face instantly started burning, and she bashfully looked away. Why did Ana's impassionate delivery of such lewd requests turn her on so much? Ana's whole personality was a strangely effective enigma.

"We don't even know if that's what's coming up," Natalie mumbled.

"Combat, fucking, combat. Three makes a pattern. I find it a safe assumption."

"And you're really looking forward to it, are you?" Natalie shot back.

"As much as you are, if I had to guess." Ana's lips twitched. "Which is to say, very much. I'm itching to get going. Now, hurry up." She made a shooing motion. "Staring at your ass all day has me pent up."

Natalie didn't have a retort for that—she never had a retort to Ana's complete lack of shame—so, red-faced, she swung open the hallway door and advanced. The two girls passed by a familiar ladder, and sure enough, above the next doorway was the same pink gemstone they'd seen heralding the first lewd challenge. It really was alternating combat and fucking, then. Three suggested a pattern, but four confirmed it.

Having all but known this was coming, she refused to hesitate. She already didn't like how much of a blushing mess this had turned her into, so she could at least face her fate with squared shoulders.

And no, it wasn't because she was itching to get started, like Ana had implied. Ana might have bullied an admittance like that out of her by getting up in her face, but Natalie wasn't such a massive pervert that she was squirming to have her own cock inside her. She had some dignity.

She did.

Or, at least, she was going to keep telling herself that.

Regardless, she swung open the door and strode in, hammer held at the ready. Inside, a familiar aesthetic met them: polished tiles, statues, and, making her stomach clench in either nervousness or something Natalie didn't look closely at, there was a bed in the center of the room. The last confirmation they needed.

Worse, even, was that a large plaque inscribed with instructions laid on a plinth, offset from the bed. Instructions couldn't bode anything good, not when Liz's challenge had set the standard.

The last objects of note were the three doorways leading out—all locked. The first had a single circular gemstone above it, glowing a dull, faint pink. The second had two, and the third had three. Natalie didn't know what that meant, but she assumed the instructions would explain it to them.

"It gave us a bed again," Ana commented. "We should use it, this time. Spurning a gracious host is rude, Natalie."

Natalie ignored her. She scanned the room for traps, then approached the plinth holding the challenge's instructions.

***

Inscribe the Mark of Carnal Absorption by pressing the formation stone into one's pubic region. The bearer of this mark, upon climax, will shatter a Seal, unlocking passages to higher-tier rewards.

The mark will fade ten minutes after entry. All surviving Seals past the mark's dissolution will become impossible to break.

***

"Tiered rewards," Ana said. "Interesting. And there's six total—that's a lot of cumming." She plucked up the small stone sitting on the plinth and turned it side to side. Red-violet lines covered it in an intricate magical diagram. "A formation stone." Ana hummed as she peered at the novel item. "We shouldn't wait. The timer started when we came in. The question is, which of us will come to climax easiest? And most often?" Her lips curled up in vague amusement as she turned to Natalie. "No need to answer." She placed the cold stone against Natalie's pubic area, a few inches above her pussy, then pushed. "We both know it'll be you." The stone sank into her, and glowing violet-red lines scrawled across her skin, forming an intricate tattoo in the shape of a stylized womb.

Ana pushed Natalie, and the action was so surprising, she stumbled and fell onto the bed. Ana pursued, crawling over her.

"Six times," Ana said. "That seems easy enough. I wonder if there's a bonus for going above and beyond." She brought her face close to Natalie, mumbling her next words—tickling Natalie with hot air. "And it's about time. I'm so tired of waiting."

"I-It just says climax," Natalie replied, heart slamming at Ana's sudden proximity—and the way Ana's cock pressed against her stomach. "We don't have to go too far. We don't have to do anything rash."

"How else will I make you climax six times?" She leaned forward, bit Natalie's lower lip, and tugged back gently. "For the next ten minutes, you're mine. And I promise—I'm going to be thorough."

4.46 - ❤ Swapped XII & XIII

Natalie's head spun at how quickly this was advancing, but Ana had a point—they were literally on a timer.

A timer. That measured how many times Natalie came to climax. And unlocked stronger rewards the more she did?

What an absurd challenge. Maybe even something as straightforward as the blowjob room was preferable.

As for Ana's implications: that she would be claiming Natalie however she wanted. She didn't know how to feel about that. A part of her had been clinging to the excuse that she was working her way through the dungeon, doing what it told her. Now, though, it just said she had to cum. They could definitely arrange that without Ana fucking her. Without Ana doing anything. Nothing said masturbation was off the table. Natalie could take care of herself.

But Ana didn't seem to care about that possibility. Natalie was forced to confront the fact that the stoic mage really did just want to fuck her. That all her lewd words and her domineering attitude hadn't been for show.

And Natalie was going to let her. Because she wanted it too. She wanted to be fucked by her own cock. She was going to lose her cock-virginity to herself—and Ana at the same time. The idea made her dizzy.

"You're so red," Ana said, cupping her cheek, which Natalie couldn't help but crane into. "It's cute. I can't wait to see how you react when I stuff you. When I'm so deep inside you, I'm kissing your womb. I bet you'll really be blushing, then."

Natalie shivered at the mental image, then shivered again as Ana leaned up and placed a hand against her pubic region. She examined the designs of the glowing symbol there, tracing lines with a finger.

"I wonder how much you can take?" Ana mused. "Before you break. You're so pent-up, it's adorable. You need this. Badly. How quickly can I turn you into a whimpering mess?"

Ana gripped her cock, then slapped it against Natalie's pussy. She wiggled her hips, grinding her member side to side, then up and down, and the contact made Natalie's toes curl. It felt good. Way too good. Even just having her lips spread apart as Ana's cock rubbed between them nearly drove her insane.

'Pent up'. Yeah, that was an understatement.

"You're soaking already. You're that eager for my cock?" Ana pressed harder, digging her shaft deeper between her lips, and Natalie gasped, her back involuntarily arching. "Or is it because it's your cock?" Ana murmured. "Are you this much of a slut for yourself?"

Natalie's face burned. She wanted to deny it, but the only thing that escaped her mouth was breathless panting as Ana continued to grind against her.

"That's right," Ana said. "I've got your own cock pressed against you. Soon, I'll shove it inside. Isn't that so dirty? Naughty? Degenerate?" She smirked down at Natalie. "What if Jordan saw you? Sofia? Elizabeth? What if they saw how desperately you're squirming, your body begging to take your own cock? How do you think they'd react?"

Ana pulled her hips back and pressed the tip of her member against Natalie's opening. She didn't push, just left it resting there, pulsing heat into her. Leaking precum.

Natalie stared down her body. Ana's cock looked even bigger from this perspective, the image cradled between her breasts—Ana's breasts—and poised at her pussy, about to enter. Could she even handle something that huge? It didn't look like it would fit.

And why did cock look so good on a girl? Ana's meaty length, resting just a few inches from her pussy, situated so perfectly between thick, curvy thighs, was a sight that made Natalie's body heat up in ways she'd never expected.

Girl cock was just so ... amazing.

"H-Hurry up, already," Natalie mumbled. "We're on a timer, aren't we?"

"Is that it?" Ana said, sounding amused. "We're on a timer? Natalie, we both know you're just impatient. You want your cock. Admit it."

Natalie squirmed under the accusation. It wasn't like it was the first time she'd heard it, but with Ana so close to thrusting inside, the taunting was hitting her harder than before.

"And there's not that much of a rush," Ana continued. "Because with you like this, six times will be easy." Ana shifted her cock around, digging the tip of it into Natalie's lower lips. She pushed a half-inch forward, the thick member slowly sinking inside, stretching Natalie but not enough to penetrate her. "But if you want me to hurry, I can. You'll just have to beg."

"Beg?" Natalie asked dizzily, unable to tear her eyes away from Ana's cock, so close to sliding in. Why hadn't she shoved inside her yet? What was taking so long?

"Beg," Ana repeated. "If you want my cock that bad, then you'll have to beg me for it. Or I'll sit like this until you do." She wiggled her hips, squirming her cocktip around Natalie's pussy lips.

She couldn't be serious. Wasn't this situation mortifying enough? Ana knew how embarrassed she was by it all—she had forcibly extracted those admissions.
