Layla's horniness and placing the spy equipment

"You did well holding out until now. I'm sure people will start waking up soon so let's stop here for now."

I smiled as I got off from Nina's bed, looking at the hot girl who lied motionlessly on her front, her asshole which I had fucked few times, releasing a total of three loads inside her, was opened up and would take some time to recover and tighten up again.

Nina's belly was filled with plenty of semen, which only now began to slowly leak out. Her face was drown in pleasure, but she kept saying she didn't like it even though she had been climaxing like crazy.

"W-whhon't. S-shurrennderrr," she said softly.

I admired her spirit, but there was no way she could win the bet. The sooner she realized that and just give up, the better.

"We'll see about that. See you later, make sure nobody sees the mark, otherwise they'll realize you belong to me."

I then covertly left Nina's room and walked to my own. As I entered the room I was a bit surprised seeing the spectacle on my bed.

After all Layla was on the bed, fully nude, as she was furiously masturbating, her sexy fingers delving deep into her pussy, as she kneaded her huge tits with her other hands.

"I've been gone a bit and you're already like this? What a horny lewd sex slave."

Layla noticed me and said: "Master, I want it, I want master's dick."

"Hmmm, what a naughty woman you are. But right now I'm not in the mood, so go ahead and start up breakfast."

"EH?" Layla looked at me surprised, after all usually I would enter her immediately.

"W-why not master?"

"Since when do I need to explain myself to you?" I said smiling, enjoying the stunned look on her face.

"T-that's I'm sorry master. B-but I-I really want it."

"Oh, but I don't at the minute."

Layla was stunned not having expected I would ever turn her down.

"B-but."

"Layla, tell me what are you again?"

"I-I'm master's sex slave."

"That's right, so tell me when I want it do you have to spread your legs for me, no matter your mood?"

"Of course, I'll always have my pussy available for master if he wants it."

"Good, now if you want it and I don't does I have to stick it in either way?"

Layla gulped as she softly shook her head, "N-no, master doesn't have to, b-but."

"No more buts."

"Yes master."

"Good now for your punishment, you're forbidden from sexually touching yourself got it?"

"Y-yes master."

Layla looked sad, but for now I didn't care. I've already had plenty of fun with Nina and while I could still easily get it up for Layla, right now was about teaching her a lesson.

No matter how lewd her body becomes and how horny she is, she should accept the fact we're only going to do it when I want to.

So I turned this into a test to see how obedient Layla was. If she went against me due to her high horniness I would have to reprimand her a lot.

While I loved making her body as lewd and horny as possible, she still needed to be able to restrain herself.

Naturally I had to put a reward in it as well.

"If you can go all day long without sex or masturbating, I'll make sure to reward you plenty tonight, so make sure to restrain yourself."

When Layla heard my words she instantly got happy again thinking of the future where I would fuck her brains out.

"Yes master, I'll definitely hold out till tonight."

"Good girl, now go whip me up some food."

"Yes master," she said happily leaving the room, still naked as she went to her own and got changed. Harry not noticing a thing that his wife had been turned into a lewd sex slave.

I then resumed my morning and began my daily work-out routine of running and strength training.

After working out I showered and went downstairs where breakfast had been prepared. Smiling I looked at Layla who was constantly wiggling her legs together, while a small blush was on her face. It seemed she was still fully in heat and wanted to do it.

At the table as well sat an embarrassed Nina who didn't dare match her eyes with mine. I had fucked her asshole plenty already, making sure it would take her quite some time to get all the semen out her butt, only increasing her embarrassment.

Still I would make sure to shame her plenty more, to turn her into the perfect masochist.

While the mother and eldest daughter, both felt different emotions all linked to me, the younger daughter and the husband/father, ate breakfast not noticing anything different.

As breakfast ended Harry suddenly gave some amazing news again.

"Oh right I haven't told you yet, I'll have to go away for a few days again from tomorrow onward. I'll probably come back Thursday or Friday."

Usually Layla wouldn't be all to happy about her husband leaving, now though she had to work hard to contain her joy, after all it meant we could sleep together again.

"A-ah yes, w-well be sure to come back quickly," she said trying not to arouse suspicion.

Layla immediately looked at me as she licked her lips.

I just smiled and gave her a wink in return, causing a shiver go through her entire body.

After breakfast I went back to my bedroom to browse through the shop, after all Harry's business trips wasn't just fortunate so I could have lots of sex with Layla.

It was also a chance to see what was actually going on.

I just didn't believe he only went on business trips, for purely business.

Even though he held quite a high position in a good company, something didn't add up. My main suspicion was the fact he let his amazingly beautiful wife go unsatisfied for a long time.

I was fucking her everyday and I wasn't growing tired of her in the slightest. The opposite in fact I couldn't get enough of her body.

The only reason I turned her down this morning was to teach her a lesson. I was close to just fucking her hard this morning when I saw her lewdly playing with herself in my bed and I had to restrain myself big time.

In the shop I bought a few items with all the remaining points I had. It included a tracker, along with a listening device.

These things were far more expensive than the lube and restrains I used on Nina.

Luckily everything went okay with Nina's enslavement.

If it hadn't I had a contingency plan in place, which included using up all my points to buy a single-use item.

The item would purge last night's memories from Nina's mind and we could go on to live without Nina remembering me tying her up and having my way with her amazing tits, while also trying to put a slave mark on her body.

Luckily though my plan worked and I could now enjoy myself with her amazing body whenever I want.

The memory purge item would've cost me all the points I had, but I didn't need to buy it, so I could buy the spy equipment.

After I bought the two tools, I made my way down and when nobody was looking I placed the items in Harry's bag, he always took with him.

Immediately the location of the tracker was shown on my map. Unlike normal trackers which used GPS, mine was used by the all-powerfull system and thus needed no satellites whatsoever.

The listening device worked the same. I could switch it on using the system and all sounds heard through it would be transmitted directly into my head, just like I could hear Layla's thoughts.

Having succeeded in placing the devices and checking how they worked I went back upstairs, instead of my own room though I walked into Nina's without knocking.

Immediately Nina who sat at her desk looked at me and got nervous.

"W-what are you doing here?"

"I'm here to play," I said smiling.

Nina gulped as she said: "I-I'm doing homework, I don't have time to play."

"Oh since when do you do homework in the weekend? You never cared to do it before."

"T-today is different, now please leave so I can focus."

I smiled and said: "Nina show me your crotch."

She gulped and turned her chair towards me, "n-no don't make do things again."

She still raised her shirt though showing me the slave mark etched onto crotch.

"Now tell me what that means."

"T-that I'm your slave and have to obey you."

"Exactly."

"S-still our bet."

"Our bet doesn't change the fact you still are mine and as long the month isn't over and you haven't won, I get to do as I please with your body. Now as the others are up and awake in the house we can't have anal sex, but that doesn't mean we can't indulge ourselves in each other's bodies and get to know each other more intimate can we?"

She swallowed her saliva once more, realizing I was far from done with her.

"Loose the shirt and bra and get on top of the bed. It's playtime," I said putting on an evil grin.
