Emma was relaxing in her corner in the muddy water of the Rio Negro Hot Springs, on vacation with her husband and a couple of his friends whose presence she could no longer stand. The volcanic mud, thick and warm, enveloped her like a second skin. She felt the fine particles of sulfur and magnesium lightly prickle her skin, a heady mixture of very light rotten-egg and damp earth heated from the depths. Each movement made this ash-grey paste ripple around her, sticky, almost alive, seeming to invite her body to let go.

"Ah, there you are," said Liam, approaching her in the muddy bath.

Emma was jolted from her thoughts and frowned as she saw the man she despised approaching.

"I've already told you, leave me alone," Emma replied sharply.

Liam continued to approach, a smirk on his lips. The muddy water, opaque and ash-gray, made it impossible to see what was happening underwater, but she felt Liam's hand settle on her hip. The contact sent a shiver down her spine.

"Stop that right now, or I'll call Nathan and tell him what you're doing," Emma said coldly.

"Oh yeah? Why didn't you say anything last night when I stroked your bare leg under the table at dinner?"

Emma blushed slightly.

"And personally, I thought you took your time reacting before removing my hand. If my wife and your husband hadn't been there, I wonder if you would have even removed it," Liam sneered, slowly sliding his palm up her body until it reached the base of her breasts.

"Emma?" called Nathan from a little too loudly nearby.

As she was about to answer, she was cut short by the sensation of Liam's hand slipping inside her bikini bottoms.

"What are you doing?" she whispered as her eyes opened wide.

Liam's expert fingers went to work, and Emma threw her head back, her mouth half-open in response to his actions. Liam couldn't suppress an arrogant smile at the erotic sight of this haughty woman who finally seemed to be giving in to his advances. Each of her lip tremors, each of her erratic breaths, seemed to crack the thin layer of mud on her body a little more. She had all the hallmarks of a volcano about to erupt.

"I'm offering you a little relaxation, you really need it. Your husband can wait a bit," he whispered to her with a wicked smile, glancing sideways at Nathan.

"Emma?" the voice insisted from nearby.

"Stop... stop it," Emma managed to say.

Against all odds, Liam actually stopped completely and raised an eyebrow. "Really?"

Emma didn't move, her head still tilted back, her eyes closed.

"You can leave whenever you want, you know," Liam continued with a smirk.

Emma bit her lip, and he felt a very slight, almost involuntary movement of her hips toward his hand. He moved even closer and whispered, "That's what I thought" in her ear as he inserted his first finger inside her.

Emma inhaled sharply, her mouth opening wider to draw in more air.

Liam, continuing his lewd actions, watched Emma. Her body was covered in a thick layer of volcanic mud, dried in places, forming fine grayish cracks, sinuous lines of breath on her chest. Her coppery-red hair, damp and sticky in spots, further accentuated the contrast, giving her an intensely disturbing, primitive, almost bestial image.

"I can't wait to fuck you in your hotel room," he whispered, inserting a second finger which he curled into a hook, firmly pressing against the inner wall while his thumb rolled hard over her swollen clitoris.

A faint moan, almost inaudible over the outside noise, escaped Emma's lips as she placed her arms on either side of the edge for balance.

"You... you can't... your wife... your best friend..." she managed to say, her head still tilted back, her eyes closed.

Liam smiled. "My wife is my story, and as for my best friend, it's precisely because you're my best friend's wife that I want you," he said before burying his face in Emma's offered neck. The movement of his fingers quickened as he began a voracious kiss on her neck. His tongue makes contact with her quivering skin, finally tasting the sweat of her skin altered by the mineral taste of volcanic earth. His fingers, coated in this warm, silky mud, slid deeper, the slippery texture amplifying each caress.

Emma couldn't suppress another moan, this time a little louder.

This was followed by snickers from the girls nearby, probably amused by the situation. The reminder that she was in full view should have brought her back down to earth, but it only made her tremble a little more.

Liam paused and looked at the red mark he had left on her neck with a satisfied expression before resuming his whispers in Emma's ear: "Your husband has always been an arrogant little prick who looks down on me. That's why I've fucked every one of his girlfriends." Liam continued to quicken the movement of his fingers, feeling Emma's body tremble, signaling an imminent, liberating orgasm.

"And that's why I'm going to fuck his wife."

Feeling Emma's body tremble under his touch, Liam smiled more broadly. He knew exactly what he was doing: forcing her to confront what she hated most about him and herself. She hated this man and his unbearable arrogance, the fact that he pretended to be Nathan's best friend while trying to add his wife to his list of conquests just to feed his inflated ego, the fact that he touched her, defiled her, and turned this moment of relaxation into a dirty, sordid, filthy, and degrading orgy. She hated it and loved it so much at the same time. And she hated herself for that thought.

"Nev… Never," Emma tried to reply, without much conviction.

Emma felt the mud seep into her and against her clitoris, swollen beneath the merciless thumb, making her feel as though she were becoming one with her surroundings. The sulfurous smell rose stronger to his nostrils, almost overpowering, seeping a little more into his lungs with each ragged breath.

"Oh but I will, my dear Emma. And ​​I won't just fuck you, I will defile you. I can assure you, you will have the taste of my cum in your mouth before the end of the week," continued in a hoarse whisper.

Each caress from him was an insult to Nathan, breaking her a little more, much to Liam's satisfaction. Against all logic, against all dignity, her body was responding. Her inner walls contracted around his fingers, inviting them to go deeper, the warm mud amplifying every sensation. The more she despised him, the more her body rebelled, desperately seeking the release he was imposing.

They heard Nathan call out a little louder, "Emma?"

The mud hid her vulnerability from the eyes of passersby. But below, it was pure chaos. She gripped the rough edge of the pool, trying to regain her senses, but it was too late. Her hips were no longer obeying her, they rolled once more against his hand, seeking more pressure. Shame overwhelmed her. Each mental insult she screamed at him was instantly transformed into an electric shock through her body, trying to hold back an orgasm she refused to accept.

"You hate me, don't you?" he murmured with a triumphant smile, "I can feel your anger in the spasms that tightens around my fingers."

She could no longer respond, consumed by the pleasure that invaded her body and mind, her eyes half-closed.

"You're going to come for me. That's what makes it so good, Emma. Hate makes everything more intense."

She bit her lip until it bled to stifle her cry.

"That's it. Come. Let your pleasure take over and become the woman you are deep inside," Liam told her with a predatory smile.

Unable to hold back any longer, and sensing that she was about to scream with pleasure, Emma finally let herself go.

She sank slowly beneath the opaque surface, swallowed by the volcanic mud. The thick, warm substance enveloped her entirely, sliding over her skin, filling her half-open, screaming mouth with a salty, sulfurous, mineral taste. The Earth seemed to be pulling it towards its magnetic depths. She descended, cradled by the last burning waves of her orgasm that continued to pulse through her body, slow and deep. Her limbs relaxed little by little, surrendering to this warm gravity that drew her downward. For a few seconds that seemed like an eternity to her, she felt dissolved, defeated, and strangely at peace.

The lack of air became unbearable. Her lungs burned, reality slapped her back. With a violent leap, Emma returned to the surface, piercing the gray layer, as if being born anew.

She was almost entirely covered in mud, concealing her cheeks flushed from the orgasm she had just experienced. She saw Liam walking towards Nathan, a smile on his lips, waving at him.

"Ah, there you are! We've been looking everywhere for you with Emma," Liam exclaimed cheerfully.

Emma remained still.

Seeing him behave like that with her husband after what he had just done filled her with hatred and desire.
