After Yukari had successfully completed her first mission for Jejuna she was rewarded with twenty gold coins and told to live in a nearby inn until summoned. She had been borderline unable to contain her impulse just to push the frog demon down and mount him from anger. Though as Yukari was not confident enough being able to defeat him even without the golems she had no other choice but to accept it with gritted teeth if she wanted to get more of the divine semen.
So Yukari was sitting at the balcony of her inn room disguised as a black-haired travelling doctor in white robes. She leaned to the railing while looking at the people flowing along the busy market street. Eventually one strong enough would come that was worth her time even as she could sustain herself for weeks with Jejuna's potent load if she did not spend it by straining her body too much.
Suddenly a loud knocking from the door echoed in the room. With mild annoyance, Yukari walked to the door to open it. Behind it was the plain-looking human innkeeper.
"Please help us, great healer, a demon has attacked one of the staff. He is being corrupted by demonic essence even as we speak," the innkeeper pleaded the moment the door opened. Yukari's disguised silver eyes of a high-ranking healer gave a pondering look at him.
"Fine but if the essence is not strong enough I won't care," Yukari muttered.
"Thank you, this way if you may," the innkeep voiced trying to hide any annoyance that might have triggered in him. He had clearly dealt with eccentric master healers before.
Yukari was led down the stairs to a bedroom where several people surrounded a single human male laying on the bed. She went straight past them to stand next to the patient. His facial veins were bulged while his reddened eyes stared at the roof fully glazed like he was no longer there.
"Can you save him?" the innkeep asked before Yukari had even figured out how strong the demonic essence corrupting the human was.
"Leave us. If you want to live do not disturb me," Yukari flared a bit annoyed. So many humans who lacked magic around her almost smelled bad to her.
"Yes, right away," the innkeep voiced and pushed everybody else out of the room before himself. There were several hostile glances at Yukari but everybody kept it for themselves.
Once left alone Yukari knelt down to jerk the human's pants to reveal his flaccid cock. Then she gripped from his balls and made her hand glow softly while she used a technique to lure all rogue demonic essence into the marbles. The veins on his face lessened while his eyes lost some of the red hue. Though his cock began to twitch while it turned red.
"Feels pretty strong, I got lucky," Yukari mused while gripping harder on the balls that tried to grow in her hand as the demonic corruption focused into them. Her eyes were locked on the cock that grew and swelled beyond natural human limits while it was twisted by demonic bulged veins and clumps.
"A bit more and... done," Yukari voiced when she felt all of the foreign essence in the human's body to be locked into his bloated balls. After that, she did not waste time to warp her lips around the burning hot tip that was almost rock hard. She tasted some traces of human semen but none of it compared to the load that was now cooking up in his balls.
Yukari slid her lips up and down the human's cock while she used her mouth to apply as much pressure on its tip as possible. She hadn't experienced the sweet taste of semen on her lips for a few days so she was being even more impatient than usual. Her breathing grew ragged while she took the rock-hard bloated tip into her throat at every bob of her head.
Thick kitsune saliva dripped on the human's balls that were still being gripped by Yukari's hand. She had to keep forcing the rogue demonic essence to stay mixed with the semen to get as much of it out as possible to feast on it.
The longer the human cock refused to cum the harder Yukari's eyes grew. Even if it had been less than a minute the raw taste of ordinary mortal flesh sliding along her sensitive tongue was starting to get to her despite it having a bit of demonic flavour.
So Yukari wrapped her long tongue around the human's tip and began a focused assault on it to finish the increasingly annoying struggle as fast as possible. She showed no mercy while her wrapped tongue pulsed around the tip. It might have lasted only seconds but to Yukari, it felt like she was being forced to kiss a powerless human for hours.
"Argghgh," a weird feral groan came from the human's lips who was like in a feverish coma. A moment later a demon essence laced semen shot into Yukari's throat. She swallowed it down with glee while milking the cock with her lips and tongue. Even as it stayed hard the unnatural swelling lessened while the demonic corruption was forced out by Yukari's technique.
For several minutes Yukari kept giving her all to suck out anything the cock was willing to give her in one almost uninterrupted suck that only a demon could give. The taste of the semen in her stomach was a bit more potent than she had expected and could sustain her a few more days. It was not much with her current magical storage that would let her live for weeks but making sure not a drop was wasted was definitely worth her time.
Yukari did not let go until the human's cock turned limp in her mouth and every drop of even watery seed was forced out. Once she was done the human only had small traces of demonic essence in him that would naturally fade in hours.
"There, you healed now. You better appreciate it, low-level weakling. You better thank the fact the demon who attacked you was strong enough for me to bother," With an annoyed eye roll Yukari covered up the human's cock with his pants and stood up. Though she did lick her lips to make sure nothing had spilt even if she would have been able to feel it on her skin.
After that Yukari went and opened the door. The humans surged in immediately and saw how the patient's condition had improved just from the lack of demonic signs despite his feverish condition.
"Thank you for saving him," the innkeep voiced with a bow to Yukari.
"We can never forget this deed. How can we repay you?" a woman who had not spoken to Yukari before asked on her knees.
"Where was he attacked?" Yukari asked while trying to avoid eye-contact with the plain-looking humans.
"The storage basement, I have it locked until the martial experts get here so no need to worry," the innkeep replied.
"Let me inspect it," Yukari voiced.
