Worthy Core

Sincere groans as he sits on the side of the bed, his palm resting on the top of Lollyp's head as she easily deepthroats his entire length. "Ung! Wouldn't...wouldn't you say this counts as round three? Whatever happened to 'just one round'?"

Lollyp pulls off of him with a plop, then begins counting on her fingers. "Well, we both got off during missionary, but that just counts as one round. Neither of us finished during doggystyle, so that doesn't count at all. You did fingerbang me pretty good, but fingering hardly counts as a round! And blowjobs are just a, like, in-between rounds thing, so we haven't actually started round two yet, right?" She turns to glance behind her. "Besides, Xenia's not back yet, sooo..."

This time the demon groans for an entirely different reason. "Is that really how they teach mathematics in the slime pools? Besides, there is the matter of my poor anatomy to consider." He reaches down to pull Lollyp up off the floor, and his slimy partner responds by sliding her way up his body. By time she's settled again she's sitting in his lap, legs straddling his waist and his dick somehow fully embedded in her without any actual insertion ever happening. "You little vixen, hng..."

Lollyp grins as she licks her way across his chest with a tongue that grows as long as she wills it to. "What's that about your 'poor anatomy'? Seems to be doing just fine from where I'm sitting."

Sincere returns the grin, through somewhat forced. "Unfortunately, dungeon boss forms are not all created equally. As a boss-level slime, physicality and endurance are rather your 'thing', yes? While my form is intended to be little more than the anonymous figure in a crowd in a stage play. Without the proper pacing, I'm afraid I stand little chance of being able to keep up with you for long."

Scoffing, the slime boss slaps his shoulder. "Where'd all that confidence and ego go!? You've only popped off once, and I can feel how much fun you're having right now, so don't tell me you're already tiring out."

"Oh, I daresay I can do quite a bit more for you still. However, if you enjoy feeling how much fun I'm having, you'll have to give me a bit more recovery time or your fun may...deflate."

"Pffft." Lollyp eyes the demon, then turns aside for a moment, lost in thought. "...You know, I've got something I haven't actually tested yet, but...hey, we're both immortal now, so if it kills you, you'll get better! You wait right there!" Before Sincere can say a word she slides directly off of him before running to the shortcut portal back to the Floor Two apartments.

"I swear to the divines, if the women of this dungeon manage to kill me through sex twice..." The man's grumbling is cut off when Lollyp returns a moment later, holding a vial of purple liquid in her hand.

"Latest product from Lollyp's Alchemical Alcove! It's a base stamina potion, combined with an aphrodisiac recipe using our forest ingredients. Should be exactly what you need to keep the Lil' Sinner in the fight!"

He takes the vial, but doesn't exactly rush to swallow it down. "A Potion of Night Stamina? Who exactly were you making this for, again? You say you haven't been testing it yourself?"

Lollyp chuckles. "Well, like you said, I don't exactly need the thing. Xen wouldn't either, and she couldn't drink it anyhow. But I was thinking as a possible loot reward...well, I don't know! I heard the recipe once and I wanted to try it out!"

Sincere sighs, then shrugs. "In the name of science, then." As Lollyp returns to his lap he pops the cork and swallows it down, before smacking his lips. "Flavor is a bit muddy...I can certainly taste the stamina potion, but it lacks the sweet taste of the average aphrodisiac...perhaps more fruit?"

"I wasn't exactly mixing for taste, alright!? So...how do you feel?"

"I suppose..." Sincere trails off before his eyes go wide. "That's...huh. I feel...I can see..." He lifts one hand and stares at it for a while. "The illusion, coating my base form. I can see its structure, how it holds together. Illusions were never my specialty, even with Xenia sharing knowledge of the Illusionary Demon spell with me, I never saw it just so...clearly before."

"That...might be the mushrooms talking? Okay, bit of a side-effect I guess, but not too bad, right?"

"This form...in a way, are we not all illusions? Merely clay, shaped by the whims of our master?"

Lollyp eyes the demon cautiously. "Well I mean, I'm a slime, so I get shaped by her pretty often if you know what I'm saying, haha...seriously though, you alright Sincere?" The answer she gets makes her squeak in surprise as she suddenly feels the organ inside her begin to grow - which is impressive, considering it had already been at full mast before. As she looks down, staring at it through her own transparent torso, she realizes something - the Illusionary Demon spell can change a monster's appearance, but not its actual shape. As the demon dick inside her becomes longer, thicker, more veined, she realizes the change isn't an illusion - Sincere's actually growing larger.

Looking back up, she realizes it's not just his cock, either. His shoulders ripple and stretch, growing wider, and the next thing she knows her entire waist has been gripped in one single gigantic hand, holding her tight as Sincere begins to stand up. The change isn't an even one, at least while it's in progress, but a minute or two later she finds herself literally in the hands of an entirely new Sincere - one a good ten feet tall, proportioned like a draconic but at a scale eclipsing even her own former dungeon master. His demonhood hadn't been left behind either, and the next time she looks down she finds well over a foot of red-skinned demon meat impaling its way through her torso. "Sincere!?"

Grinning down at her with a mouth that now seems to contain far more fangs than it did a moment before, the man answers. "It seems your potion has more than just granted me stamina...but also the need to use it. I...don't think I can restrain myself much longer. If you wish to make your escape..."

Instead, Lollyp's legs wrap their way around his waist, joining together on the other side in a tight ring of slime-flesh. "Not the effect I was going for, but I ain't callin' the experiment a failure either, not yet anyhow! Show me what you got!"

With no response beyond a groan, the hand gripping Lollyp's waist slides her up off his dick, pausing just before exiting her entirely. Lollyp moans herself, her newly-stretched tunnel feeling some relief as it's able to shrink back down to its original state, but it gets little chance to remain that way. With a force that would probably kill most mortal women the enhanced Sincere slams her back down, and the sudden internal expansion makes the slime's form grow and bulge in a number of unsightly ways. "Oh, gods! Sincere, gotta warn a gal before an impalement like that!"

Sincere's mouth opens once or twice, but the man now seems almost incapable of speech, his communication limited to his eyes as they scan her up and down. Once again he pulls her back up, and on the next thrust she's ready, her body already stretched out to accommodate his unusual size. On the following thrust, as her senses somewhat return to her, Lollyp realizes she can do even more than just lie back and let Sincere use her. Focusing on the loop she's formed around his waist, she turns her membrane as elastic as possible, meaning that the next time he pulls her back she snaps down onto him as if she were made of rubber. The impact of it is stronger than anything she's felt before, nearly knocking her unconscious, which is a feat even mortal combat had so far failed to ever accomplish. Still, she can't bring herself to let it stop. "Ah! Ah! Gods, when it hits me, right in the back of - ah! Oh my gods!"

The two continue like that for another few minutes, until the nearly-insensate slime eventually realizes that Sincere's stopped for some reason. Regaining control of her neck and looking down, she finds the cause - the tip of Sincere's cock is now jutting out of her torso, enjoying the open air just below her breasts. Even in his current monstrous state, Sincere's face shows clear signs of concern. "...Bad?"

Lollyp sucks in a breath. "Normally...a little bad, yeah, given I wasn't um, ready for it. But I've already turned all my pain receptors into pleasure ones, and it's not like you can actually kill me, so...fuck it? There's a point where maybe we should have stopped and we've definitely passed it, so I say, let's keep going and see how it turns out?"

Sincere's ability to comprehend is a little uncertain, but he does at least recognize the phrase 'keep going', and he soon does so. Resuming his thrusts, he now fully penetrates through his partner on every go, and a little further up her torso each time as well. Not because he's somehow growing even larger, but because Lollyp's body is actually compressing from the combined force of their movements, the hand around her waist gripping her ever tighter. At a certain point Lollyp gets yet another idea and grabs hold of her breasts, pumping a little extra juice into them as she does so. The next time Sincere's cock emerges she presses its tip between her cleavage, fucking and tit-fucking the man simultaneously. "This is the hottest fucking - ah! Thing I've ever done in my, ah, life!"

Her most powerful orgasm yet hits her at that point, and the slime's body begins to slump. While her hands remain in place, pressing her tits together, her head droops back behind her and her waist-looped legs begin to lose some of their gripping power. So it is that when Sincere climaxes himself not long after, the first blast shoots over her face, painting the opposite wall - but only the first blast. Grabbing hold of Lollyp's head with his other hand, Sincere pulls her back up and slams her mouth onto his tip just in time for the following ropes of cum to arrive. Lollyp's eyes go wide as the semen makes its journey through the giant, throbbing organ inside her, traveling through her cunt, between her breasts, past her lips and then finally down her throat.

At last the demon's balls stop twitching, but that by no means indicates the end of the encounter. After only a brief moment to recover, Sincere once again begins dragging Lollyp down onto his cock, but this time fucking her twice as he does so. One hand grips her waist, pressing himself through her slit, while the second remains in control of her head, facefucking her at the same time. The force of the continued battering begins to knock bits of slime off of Lollyp's form and onto the floor, and when the man looks down and realizes his dick is reaching the point where a brain would be found on most women, even he starts to worry he may have gone too far. Recognizing the look in his eyes however, Lollyp uses no small amount of effort to form herself a second mouth on the side of her head and force out two words.

"Keep...going..."

Sincere does so, for three more rounds of demon cum and and an impossible-to-count number of slime orgasms as he uses her like a sex toy. At some point the slime in his hands ceases to be Lollyp at all, too much of her body mass ejected onto the floor and wall around him, but it's not until his balls finally drain themselves that the man is able to come to his senses and realize what just happened. Whether it's the shock, the over-exertion, or the untested alchemical ingredients running through his monster body, Sincere just barely has time to realize his heart's stopped beating before he collapses onto the floor. "...Not...again..."

With a smile on her face and a spring in her step, Xenia returns home from her wandering in the Eternal Forest. "Woo! What a trip! Man, you two won't believe what happened out there, I..." The dungeon master trails off as she turns her head towards her bed, and finds a gigantic Sincere corpse lying on the floor, surrounded by splatters of red slime and white, sticky cum. She's still there gawking as the bodies eventually begin to dissolve, but even the pop-up box that appears afterwards fails to explain what just happened.

"...Okay. I am officially asking questions about this...never."
