NTR: The live-in-husband gets a perverted heart system

And Tom Harlow didn’t sleep.

Not even for an hour.

Morning light eventually crept through the curtains. Tom’s eyes were still closed when the System’s voice slid into his head, far too cheerful for the hour.

[Good morning, Host. Did you enjoy the concert last night? Your wife has impressive stamina. And volume.]

Tom’s jaw tightened. He dragged a pillow over his face as he mumbled;

"Shut up."

[That is so rude. Especially after Host spent the entire night listening to another man rearrange his wife’s insides.]

Tom didn’t answer that. He just exhaled hard through his nose.

[Yesterday’s daily tasks have been verified as complete.] The system changed the subject.

A clean chime sounded.

[Rewards issued. Random Chest acquired.]

Tom sat up slowly, rubbing the exhaustion from his face. He was eager to know what would be inside the chest.

"Open it."

In an instant response, the interface expanded. A large chest appeared and began spinning rapidly, cycling through iron, silver, blue crystal, and even a brief flash of gold before it slowed and settled on a solid wooden chest with brass corners.

The lid opened.

Three items floated out.

First: a slim, dark-red book titled **Flirty Conversations – Level 1**.

Second: a heavy black bottle of cologne with the word **PREMIUM** in clean silver letters.

Third: a bright notification which read: [+ $10,000 USD]

Tom’s eyes widened. A real, disbelieving smile broke across his face.

"Ten thousand...?" he whispered.

Afterwards, he reached for the book. The moment his fingers touched the cover, soft light flared from the pages. Knowledge poured directly into his mind.

Then he actually opened it and started reading.

His mouth fell open in shock, heat rushing to his face because only God knows who complied the lines he was reading. They were hot.

The supposed "Level 1" lines were nothing like what he expected.

**[FLIRTY BOOK - LEVEL 1]**

[A starter pack for a man who’s never once made a woman’s breath catch. read closely, host - A limp delivery wastes a good line.]

"Those panties look like they’d look better on my floor.".

**Delivery:** Lean in slightly on "floor" just enough that she notices the space between you shrink. Pull back before she can.

"You’re already wet, aren’t you? Don’t lie. I can see it in the way you’re standing."

"That outfit should be illegal. I’m trying to be respectful and you’re not helping."

**Delivery:** Voice dropped low, unhurried. Let the pause sit there. Don’t blink first.

"I’d say I’m sorry for staring, but your body isn’t exactly asking to be ignored."

**Delivery:** Eyes drag once, slow, chest to mouth, then hold her gaze steady. One look is a compliment. Two is a threat. Only take one.

"Careful with that mouth. I’ve been thinking about what else it could be doing all day."

**Delivery:** Half-smile, said almost bored, like the thought’s been sitting there a while. If she blushes, don’t smile wider - let the silence do the work.

"Keep testing me like that and I’ll show you exactly how patient I’m not."

**Delivery:** Said low and even, no smirk. This one works because it sounds like a warning, not a joke — treat it like one.

Tom stared at the page.

"These are Level 1?" he muttered in disbelief.

[Correct.] The System sounded faintly amused. [Host’s previous standards were simply too low. These are considered basic.]

[Reminder, host: level 1 is confidence with a filthy undertone, not a filthy overtone. tease the appetite - don’t slam the whole meal on the table. that’s level 3’s job, and you are not ready for level 3.]

Despite Tom’s shock, the knowledge settled firmly into his head. The lines, the timing, the tone - all of it integrated like he had practiced them for months.

Next he picked up the cologne, dabbed it on his neck and wrists. The scent was rich, clean, and expensive. It clung to his skin like quiet confidence.

Finally he checked his account. The extra ten thousand made the balance look almost unreal. For the first time in a long while, Tom felt something close to actual hope.

At that moment, the system dinged again:

[Daily Tasks]

1. Complete a 5 km walk

2. Start the conversation first with every person you meet today

3. Do not eat any junk food

[REWARD: $10,000]

At the sight of the reward, a bright smile broke out on Tom’s face.

"I’m looking forward to completing the tasks." he muttered, partly to the system.

[How diligent.] The System’s tone was smug, but thoroughly pleased.

Then another window appeared, larger than the others.

```

[MISSION OF THE DAY]

Use what you learned from the Flirty Lv. 1 book.

Make a woman show you the underwear she is currently wearing.

[REWARD: $6,000 + 2 Charm + 1 Lust]

[FAILURE PENALTY: Temporary erectile hypersensitivity for 12 hours + -3 Charm]

```

Tom’s eyes widened in pure shock.

"You’re joking."

[Does Host want to refuse?]

He stared at the glowing text, his heart already beating faster. The reward was tempting. The penalty was nasty. And the book’s filthy lines were still sitting freshly in his head.

Tom dragged a hand down his face and muttered, "This System is going to get me killed with embarrassment."

But he didn’t refuse.
