“Do you plan to pay extra?” It wasn't the first time Lydia had negotiated for her body. “Curiosity alone isn't enough for me to give it away.”

He pulled out a pouch and dropped a strange coin of gold and crystal inside. It clinked against others already in there, and she could see a glow from within. Smiling, he watched her lift an eyebrow, unamused, so he grunted and dropped another, angry at how foolish he was being.

It seemed like he went as far as he was willing, and Lydia didn't want to push things. If he were being cheap, it would be a lesson; if he wasn't, it would be worth it. “Now we get to see if you overpaid,” She pushed out her chest as she got closer. “-or get your monies worth.”

He laughed, “Don't worry, I will get what I want from you.”

Lydia entered the apartment as he set the pouch on the table by the door. The place looked normal, as if some average person lived there. She handed the satchel to him as she noted the path from the bedroom to the front door. Wondering what he wanted to do next, she looked at him and saw that he had opened the bag facing her. An inky blackness leapt out at her and she felt the slime seep into her eyes until her vision cleared. She noticed the empty bag on the floor, wondered what had happened, then looked at the devil. He was grinning, waiting, his long tongue hanging out of his mouth, hungry with anticipation.

She wanted to ask what had happened, but she didn't care anymore as he stripped out of his clothing. Lydia leapt at the devil and kissed him, feeling his tongue slithering into her mouth. When he tried to lift off her tube top, she grabbed him by the wrists and held them up, pinning him against the wall. She felt a rush of power, being able to handle him with such strength.

“Hey now, I want to see those sweet devil-branded tits.” He explained when she let him breathe.

“Tongue, inside, now.” Lydia pushed him to his knees, in total control over him but barely in control of herself. She pulled aside her thong as she pressed her wet pussy to his face and felt the long tongue explore inside her.

It felt glorious to Lydia; never having felt a tongue so long enter her was only part of the pleasure; the other part was the power and the heightened sensation of it all. She pulled off her tube top and tossed it towards the door. Her breasts, still contained by her bra, had corrupt black veins running through them. Too sensitive, her nipples begged for attention. Trapping the man under her with her thighs, she pulled off the bra and started playing with her nipples. The sensation was too much; she climaxed hard onto the devil's face.

“Let’s lube that cock up. It has work to do.” Lydia kicked her leg over and sat down on his face, forcing him to the ground. She looked at his hard cock, throbbing in the air, **** for attention as its nubs pulsed. Usually, she would have taken time to examine the unusual tool on display, but instead, her mouth took it. She was already an expert cocksucker, but it should have been challenging to take such a size. Instead, it seemed easy, as if she didn't need to breathe. Working her mouth over it, feeling her throat fill and empty with the rapid rhythm, it wasn't enough.

“Don’t cum too quickly, or I will be very cross.” Lydia threatened the man as she got off his face, feeling his long tongue slither out of her as she pulled away. Taking the brief moment to ditch her thong, she had to push him back down before she straddled him. Rubbing her shaved pussy against his shaft for a few strokes, she pushed him inside her, climaxing again instantly.

“How upset can you really be?” He asked before realizing he was pinned again.

“You didn't warn me; you didn't explain anything. I am going to take everything I want out of you like you planned on doing to me.” Lydia responded as she slammed her hips down on him.

He couldn't talk as she moved her hips and **** him to groan in pleasure instead. Seeing her breasts bounce over his face, he licked them with his long tongue, teasing the nipples. The moans he got out of her as he did so were fiendish like him. The symbiote was working perfectly; he just hadn't expected her to be so dominant. As he felt his cock inside her, he could hardly complain. Though as he heard her climax again, he couldn't resist; he groaned and struggled as his balls emptied themselves through his cock and into the womb of the woman riding him.

Lydia was panting hard, feeling the cock inside her soften as she relaxed. The dark sexual urges subsided as she looked down at her tits that seemed to be sweating the blackness out of them. It collected into a puddle of black ink that slithered back into the bag.

“What is that thing, and where do I get my own?” Lydia asked, still on top of the man inside her, looking around for where she threw her bra.

“It’s a slime. Or part of one. It bonds with people and imparts whatever quality it has. They take months to regenerate but this was worth it.” He was in no hurry to let the woman on top of him get off as he held her by the hips. “Black slimes are always kind of kinky. Enjoy the changes it made to your body. It makes you more robust.”

“It also seems to have perked up my tits.” Lydia admired herself in the hallway mirror. “They always had a bit of sag from being big, but now they look amazing.”

“You will also be able to fit more in here.” He added, running a finger over her clit to point at where his cock still rested inside. “And elsewhere. Prepared slimes are great at making women more capable and willing.”

“This some sort of magic roofie?” Lydia asked, finally getting up and feeling his cum leak out.

“It’s more like ****, helps smooth things out or move them along. They have a hard time making people do things they don't want to do.” He explained that Lydia had fetched a towel to clean herself before redressing.

“Right, well, I will keep the paper just in case.” She slipped the job posting into the pouch. “I have more questions about that thing.”

Lydia left without actually getting all her answers, she wanted a reason to come back.
