Back in the mansion, they stood in front of a bed inside the Demon Marshal's room. This was the first time Mary saw the place, and she had to admit, this place looked kinky beyond belief...!

There were chains attached to the ceiling for bondage play where her arms would be pulled into the air and her partner would have his way with net from behind. Even on the bed, there was restraints meant for her to spread eagle in a cross fashion.

Anyway, it was incredibly kinky and not exactly to her tastes. However, she was willing to let it go. 

As long as she succeeded today, she was willing to get into any kink with him. Well… that was as long as he gave her enough time to adjust to his domination fetishes. She wasn't adverse to it.

That's all she thought.

"Should we get to it?" Zephyr still hadn't calmed down. His instincts as a Incubus was driving his lust into overdrive. The only reason he hadn't pushed her down yet was due to the contract.

If she didn't want him to touch her body, he was unable to do so. 

Even now he felt like she was cock-teasing him by seducing him but not letting her touch him. 

What was with all this hesitation?!

"We will, but only if you wear a condom." (Mary)

"I don't have any." (Zephyr)

"No worries." She pulled out a batch she secretly took from a store when he wasn't looking. 

She WAS NOT going to let there be even be chance of him impregnating her. 

This was a regular concern for her even before being sold off. The terrified girl had even took contraceptives for the off chance someone might trying to force themselves on her without warning.

She knew her own beauty pretty well, after all...

"Then..." He reached out to unbutton her shirt, but she stopped him and sat him down on the bed.

"Are you fine with me taking the lead?" Mary asked. There wouldn't have been a point of seducing him to such an extent if she was going to give control right here, that's why she asked this.

"..." Zephyr didn't have good memories of women taking the lead. The first girl who did was a dominatrix that killed his mood rather than made him feel excited. However, after getting to know her, he decided to trust. Zephyr reluctantly agreed.

"Then no painful stuff." (Zephyr)

"Alright~" Mary agreed as her heart was inwardly nervous considering this was her first time. Though she didn't show it on her face and acted like an experienced whore to seduce him even further.

They established some ground rules beforehand on what they could and couldn't do, one of them was for him to stay silent unless he had important thing to say. She wasn't interested in talking too dirty as she was thinking of ways to entice him.

One button at a time, she opened her shirt, but didn't take it off, instead teasing him intimately.

She showed off her body in a lap dance. 

An act that came more naturally when her thoughts raced between being seductive and mesmerising.

Hypnotising him with her gently swaying hips…

Like a prostitute at a strip club, she chose just how much physical contact her partner was allowed...

As his eyes wondered all over her, she lifted up a part of her skirt and allowed him to take a peak at the garter-belt her stocking were strapped to. This made his eyes concentrate solely on her figure.

Mary felt a different kind of 'dominance' as he sat before her, waiting for her to give permission to touch her. Her instincts as a Succubus started to awaken at this moment as she straddled his lap.

"What do you think?" Mary asked while allowing him to hold onto her waist. 

His hands could barely keep themselves from stripping her. Zephyr found her beautiful waist to be soft as elastic. Those cotton panties worked their magic as was grinding her waist on his leg.

The Incubus couldn't help but feel his entire body tingling with passion she rubbed her chest into his.

"This is really amazing...!" Zephyr never knew that the feeling of her body rubbing into his would be enhanced by their clothes. Even now, he was fully clothed as she quite erotically 'danced' for him...!

But they might as well had been naked.

Their clothes only becoming an aesthetically pleasing sight, as well as toys for enjoyment.

Were they role-playing with her as sex-worker and him as a wealthy businessman? He couldn't help but gasp. Mary stopped after a long while of entertaining him before they did any foreplay.

"What do you want now?" She spoke sweetly into his ear after leaning forward to push him down onto the bed. 

She was above and he was bellow as expected, yet rather than feeling like a tigress pouncing on her prey, the white lingerie on her body made her seem more like a goddess of love that came down to pleasure her faithful devotee.

"..." Zephyr didn't answer her, only moving his face closer to those seductive lips. Seeing what he was going to do, she ended up closing her eyes as their lips locked and tongues 'fought' each other.

Mary never knew that a french kiss could taste so good in her life...! Her entire body limped as pleasure invaded her heart, but her mental fortitude was strong. She kept her clarity amongst the expertly woven kissing sounds they made.

It was almost as if he was trying to suffocate her with all the kisses let loose. Not even giving her any leeway. Zephyr used his experiences as a Incubus to wrap his tongue around and suck it out.

Slowly, his body rose with Mary plastered onto him in turn. All until she took notice of the fact that they were now sitting upright. Not wanting to give him the initiative, she broke off their french kiss and pushed him down. Her body burning in heat.

"That was really good~" Even as Mary spoke that, it was actually a ploy to give her time to calm down.

"Can you do that my chest next?" Mary asked politely to the man underneath her, causing him to instantly focus less on her lips and more on her bountiful chest. 

She leaned her face forwards for him and let him kiss her mouth, cheek, all until one of those kind of kisses pecked onto her soft white bra. She had crawled forward to put her chest before him

His hand also crawled up her splendid waist, but had to restrain himself from invading underneath her bra. It was with a reluctant yet somehow satisfied expression that he fondled her chest.

He squished, groped, pinched, and plucked her chest with masterful techniques, causing her to be unable to hold back her moans. Her heartbeat sped up. Even though she still had a bra on, he sucked on her chest and covered her in saliva...

Quite the nasty bastard…

The large tent erected in his pants didn't go unnoticed. Mary looked at the man sucking her cherries with a hint of emotionless indifference in her eyes. She had gone so far, yet he still wasn't seeing 'her', only drowning himself in pleasures.

Sure, he was making her feel good, but that wasn't out of paying attention to her, instead it was due to the nature of his existence as a Incubus. 

Then, a plan formed in her head. She looked down on him with eyes filled with a light of pure clarity.

"That's enough. Can I touch you as well?" Mary spoke while moving away her chest to see his face.

"Sure~" As he said this, he became intrigued as she unbuttoned his shirt with dexterous hands.

She too became amazed as he felt up his chest underneath his shirt. Those perfectly sculpted muscles weren't possible for a human, as well as the sensation she got from touching those abs that were strong… but not overly dense in nature.

Mary could feel her body turning hot.

Wanting to grope around the same way he did.

She put her now wet chest that had been covered in saliva onto his own. Her tempting body rubbed against Zephyr, causing him to feel like he was on the verge of ejaculating from the feeling of softness coming from her moistened breasts.

Was this some sort of lube…?

Mary slithered down his chest… all until her body climbed off the bed and kneeled in front of his swelled up tent. She undid the zipper for his pants and took a look at his rod. Her partner's underwear was having a hard time holding in its majesty.

As this was actually her first time so close to the real thing, an undetectable fear arose in her heart.

Mary imagined what it would feel like to have such a think rod moving about inside of her.

What kind of pain would she feel?

It was a good thing that she predicted the size and brought enough condoms. There was an unbearable itch in her virginal opening. Her Succubi body was thirsting for his cum, but she held herself back in order to pleasure him first.

"Looks like they're flavoured... Don't you dare touch my head, alright?" This was her first time giving a blowjob or even seeing a man's most precious 'vital point' up close. She looked through the colours and chose a yellow packet in the batch.

'This is how to put in on, right?' Hiding her nervous and trembling heart, Mary remembered what she learned in Sex Ed class and slid the yellow condom onto him carefully. 

Her eyes were wide after finishing as she realised this 'banana' was still towering...! 

How was such a straight rod a banana anyway? 

What was she supposed to do now?

Again, her Succubus instincts kicked as her soft mouth made him feel the peak of pleasure. 

Seeking to already know the knob was crucial.

She reached out her tongue and lick his 'banana' to his ball sack like a cat. It's smell wasn't pleasant.

Her hands stayed beneath the glorious rod.

She put it inside her mouth with determination.

Mary could feel her hormones being activated the more she smelt such a heavy odour up close.

As if their bodies resonated.

Although this wasn't the first time the Incubus was sucked on by a female, something felt off about it this time. There was no sexual magic at work or shift in life force, and yet he felt thrilled inwardly.

As he lifted the upper half of his body again to sit straight and look at her, he was unable to stop his adrenaline pumping. Wet sounds of her 'slurping' on his rod resounded. To see the sweet girl turn so slutty 'for him' made his face become redder.

'What a nice face...' Zephyr thought as he watched her wholeheartedly put effort into pleasuring him.

Then he reached his limit, and 'it' came out...

As he wasn't a human, his sexual stamina intensified instead of falling after he ejaculated into her mouth. The condom caught it, but he could feel his mind becoming cloudy. He'd released his magical essence thanks to her 'technique'.

"Haaa.... Haaa..." Both their breathing was a mess after he 'finished'. 

He expected her to take a rest. After all, her sexual endurance shouldn't have been strong considering her nature as a mere Half-Demon, yet she ended up continuing what they started...

"You aren't going drink it?" Zephyr asked as his magical essence (semen) was a great nourishment for any Succubus. A ordinary Half-Demon like her could gain significant strength by drinking it.

"Why would I do that?" (Mary)

"It has magical properties… A potion." (Zephyr)

"Then it guess can't be wasted, can it~?" Mary spoke while taking off his condom casually.

He expected her to put it to the side, but out of his explanation, she didn't, and instead brought it up to left side of her white bra. He only understood what she was up to only after she used her deft fingers to tie it up there. His eyes twitched a little...

There was a sense of immorality in the air as she blew him a kiss, causing him to feel fired up. 

Mary put on another condom on his rod. 

The colour of it didn't matter, only that after it was put on, she started to use her soft breasts to pleasure him!

A lot of time passed by without Zephyr noticing.

Mary continued to bring him the purest forms of lustul ecstasy. She put his manhood into the gap between her breasts and bra while continuing to suck him dry like a true Succubus. 

Even though she left his life force alone, she continued to make him eject his magical essence before hanging it on her clothes. 

After much time passed, there were many used condoms tied to her underwear at this point...!

This was the first time he came so many times with merely one sexual partner, even as a Incubus,

Zephyr didn't even notice when she stopped, only feeling his legs were weak once the kneeling woman before him finally got up. After getting his attention, she tied the last condom and spoke:

"What do you think?" Mary was practically wearing a skirt made of used condoms around this point.

"Amazing...!" That was the only thing Zephyr truly thought. She put the last one to the side.

It took a few moment for her to recover her strength and tell him with all seriousness:

"Make me cum as many times as you did, without magic." That last part of her words struck him. He looked up and down her body. Within a second he was able to get up and grab onto her shoulders.

"Can I take everything off?" (Zephyr)

"Please..." (Mary)

He noticed her tired eyes… but didn't say anything more. Zephyr merely secretly using his magic not to increase her sensitivity, but to allow her to gain sufficient vitality to continue their 'activity'.

He knew that using magic when she told him not to was cheating, but he was somehow unable to see her in such a fatigued state. It was to the point that he was surprised by his own actions.

'What am I doing?' Zephyr's common sense tome him that it was common for roses to whither.

That a woman would drained due to his nature.

But one thing lead to another, and he found himself being possessed by an indescribable tenderness.

Unable to see her in any sort of pain.

His demonic nature grasped onto that feeling and amplified the protective instincts he had felt.

Corrupting it until 'love' turned into 'greed'.

Wanting nothing more than to keep her here in his arms. Even if that meant never leaving this room.

Even if that meant him dying under her control.

Zephyr finally stripped her one article of clothing at a time. Following the instructions of his contractor.

He didn't even leave her panties as she was laid bare on the bed before him. Their heartbeat synchronised. Zephyr used this chance to bring her close, all while thinking about her properly. 

Like she was the most precious thing here.

The corrupted demon was looking directly at her and thought about her feelings.

Becoming a slave to the tenderness he'd felt.
