"That, demon, is a pleasure seal. Simply put, until that seal comes off, no matter how much pleasure your body endures, you will not cum." he grins. "This particular seal has a curse attached. If enough of your love juice seeps into it, a permanent seal will attach to your soul that makes you addicted to semen." He laughs when he sees her eyes widen in shock. "By morning, you will begin repaying this town by pleasuring every man you've stolen from, and you will continue repaying them until the end of your days."
Kyu thrashed in her bonds, snarling and cursing behind her magically enforced gag. The hunter dug new tools from his pack- two fine ink brushes and a jar of what seemed to be oil. He opened the jar and dipped the first paintbrush in, saturating it in the oil as he approached his captive. Then, with the gentleness and precision of an artist, he slowly swiped the brush around her nipple, teasing her areola.
The effect was immediate. The oil was warm, and almost made her feel tingly where he trailed the brush. He teased lazy circles around her nipple, trailing away then back, then over the tips of her sensitive nipples and then repeating. When Yurio was satisfied that her right breast was coated in the oil, he repeated the whole process to the left. Kyu's head was swimming. It felt so good. Too good. She thrashed and bucked, trying to throw off the brush, but Yurio was too practiced, and it followed wherever she went. By the time her left breast was halfway coated, she began to notice that her whole body felt hot, heat that traveled straight down to her already throbbing clit.
"You've probably noticed by now," yurio taunted, "that this is a very strong aphrodisiac. One coat will leave any living creature in heat for days of end. But several coats... well, they never tested it on mortals. But you aren't mortal now, are you?"
Kyu screamed again as Yurio painted several coats if the aphrodisiac all over the most sensitive parts of her body; her breasts, her neck, her wrists, her under arms and feet too both got special attention from the oil drenched brush. The process took several hours, with Kyu writhing and sobbing in painful ecstasy. As a final touch, Yurio took a generous dollop of oil and painted it over Kyu's pink puckered asshole. Kyu groaned as he teased her entrance, her legs barely able to hold her as she tried desperately to close them against the invading brush. Finally, the hunter plunged the brush into her ass, twirling it and coating her insides with the oil. He left the brush inside her, letting it marinate as he went back to her front, smirking. The once proud and cocky demoness was now reduced to a wet and horny mess. The seal on her pussy was dripping wet, and he could see the new cursed seal had manifested itself above her entrance. The fox herself was sagged in her bonds, unmoving except for her lightly bucking hips, her pussy desperately trying to get off. With a snap of his fingers, the magic gag disappeared, leaving Kyu panting with need.
"Pleash... Need to cum... My body ish burning..."
Yurio grabbed her hair and made her look up at him. "The only way you'll ever cum again is if you swear that you will be this towns slave. Anything they want to do to you, you will comply."
"Ooooh pleash," she moaned, trembling. "I shwear, anything... just pleassssh..." she bucked her hips weakly, and satisfied that her fate was now sealed, the hunter reached down and tore the magic pleasure seal.
As soon as the seal was torn, hundreds upon hundreds of orgasms tore through the poor fox spirit. Her body shook and convulsed as it was wracked with pleasure, her mind splintering into pieces. The hunter released the magic bindings when it was clear she fell unconscious, and left her still weakly convulsing in orgasmic torture to go tell the town mayor that the fox spirit would be no trouble to them anymore.
Yurio slept in late that day, torturing a fox spirit was exhausting work. The town inn had been kind enough to give him a free room and breakfast, but now it was time for him to return to the road. The streets were bustling in celebration, centered around the town square. Yurio managed to steal a glance into the center of the festivities, and saw Kyu, bound in a pillory, with two lines formed to fuck her from the front and behind. Even some women lined up to get back at the spirit who had plagued them for so long, making her eat out their pussies or tickling her sides and feet with feathers, made even more sensitive by the aphrodisiacs lingering effect. Even if he couldn't see her, her moans and cries could be heard from the farthest reaches of the town. Yurio allowed himself to listen to the sweet music of her orgasmic torture for a little while longer before he started toward the exit, satisfied that the town was now safe from the fox spirits' wiles.
