"Aaaaaah!"

Nina felt like her entire body was on fire. She felt Eren's tongue inside her pussy and his finger up her anal cavity. The intruders slipped in and out of her tight caves with seamless synchronicity, allowing her to experience maximum pleasure.

Eren could only sigh in his head as he realized Nina had stopped sucking him as soon as he increased the level of his tongue storm. She was way too preoccupied with her emotions to please him. He couldn't blame anyone but himself for being so proficient at his job.

'Hash! I'm suffering from my success.'

Eren said to himself in a melancholy manner as he continued to do his current job. He sucked on the pink button that was Nina's clit. He ran the tip of his tongue through her pussy lips. He did that while driving the two fingers of his other hand in and out of her rear entry.

Nina kept moaning while calling out Eren's name. She started fine-tuning her nipples as she sat upright on his face, giving him full access to her cave by stretching her legs apart even further. She had her eyes closed and her tongue would show out from time to time as she breathed heavily. She started moving her hips up and down, treating Eren's intruders with the same form of affection as his dick would get soon enough.

Eren was spared from having to forcefully empty his balls into Nina's mouth since she stopped sucking him. As a result, he was more confident about making Nina come first. In a marathon, checkpoint wins don't matter. But every small victory matters to him at this point.

The sin of Lust was acting on Nina as well. It was enhancing the effects of the lust she had suppressed for so long. The mist of lust became the vent for her suppressed emotions to come out. And come out they did.

Nina's moans grew even more seductive and blatant as she started rocking her hips vigorously. Her tits kept bouncing because of her movement, making subtle flesh noises whenever her hips went down.

"Yesssss Yesssss. Erni lick your aunt's pussy well. That's it that's.. Eeeeeeeet!"

Eren's face was sprayed with Nina's love juices as she came all over his face. This was proof of a job well done in his first round. So he welcomed it with open arms and Nina's open legs.

Love juices seemed to stimulate Eren's devouring ability for some reason. As the liquid had a B-ranker's life force mixed into it, it was not something he would discard anymore.

Nina was too lost in her ecstasy to notice that her love juices had just seeped into the butcher's slime-like skin before returning to normalcy. Eren received an instant shot of rejuvenation when his half-blood Ability started extracting a strong life force from Nina's love nectar.

Nina crashed beside Eren when she was given a breather to recover from her elevated feelings of ecstasy. She was breathing heavily as if she had run up an uphill mountain road.

Eren got up and channeled his mana through his body to revitalize himself. He stood on his knees and looked at the live art he had created himself. A panting Nina with her jugs spoke volumes about the exhaustion she was suffering.

Nina looked at the wickedly smiling Eren and knew what he was thinking. She cursed herself for allowing Eren to continue using his Sine Series Ability. It was even more potent than she had thought.

"Scored one point against all odds. But who's keeping track, right? After all, this is not a game. Kekeke."

Eren said to Nina and chuckled like a hyena. He seemed proud of his pussy-eating skills that he had honed after many such sessions.

Nina hmphed at Eren before channeling her Master-rank mana throughout her body. She snapped her fingers and an incredible water element attainment manifested around her in the form of dense white fog.

Before Eren could register the changes around Nina, the fog disappeared and she was seen fresh and proper. It was as if it was not her that was suffering from post-coital fatigue, but someone else entirely.

"You are not the only one with Abilities, little devil. I have the Ability to turn all your accomplishments to zero."

Nina said confidently as she smiled at him with a tinge of provocation. Only now did Eren realize that aunt Nina had a quick recovery Ability too. And it was one of the most sought-after Abilities a healer could have in their arsenal.

Eren's eyes shone with a peculiar light as he looked at Nina with an unmasked thirst. Instead of feeling intimidated by Nina's powers, he seemed interested in them. He licked his lips and chose to reply to Nina's provocation with his actions instead.

Nina opened her arms wide while lying flat on her back. And she received her partner in her arms the next moment. He kissed and smooched her before going for her still-erect nipples.

He started sucking on one brown bud while pinching the other with his one hand. His other hand slipped between their bodies and reached for her dripping pussy. He stimulated her clit while coating his fingers in streaks of lightning mana.

A bunch of fire snakes was summoned into existence before they were assigned their respective tasks by their summoner. They began licking Nina all over her body using their hot forked tongues. Some snakes started nibbling on her earlobes. Some others bit near her armpits and neck. Her asshole was licked and the wet cunt began to drip, turning even wetter due to the snakes' activities.

The fire snakes were tasked with the job of nibbling on Nina's sensitive zones. The lightning snakes on the other hand had a job giving her small and deliberate jolts from time to time to stimulate her senses further.

Nina felt like she was being attacked from her direction when Eren started acting like a pro summoner. She was forced to lose herself in her passion once again.

'He. Aaaaah this one-track devil wants to prove a point.'

Nina had a brief realization in her head before experiencing another trip to a blissful paradise.
