"You... still being naughty..."

Nancy immediately turned her head away, her eyes closed, breathing rapid and weak, clearly still reeling from the climax.

Having reached this point was an unexpected bonus. Though still impulsive after cumming, Luis considered it wise to show restraint. After all, his sister-in-law was proud; pushing too far too quickly wouldn't be beneficial.

"Give me the tissue!"

Nancy said tremulously again.

Luis handed her the tissue, then, to her surprised expression, scooped her up in a princess carry. He carried her back to the bed, letting her lie resting in his arms.

Nancy wiped the semen from her face, acting somewhat angry, yet feeling strangely conflicted inside, wondering why she didn't find it disgusting, and even curious about the taste.

This thought startled her. Why did she find fault with everything her husband did, yet feel like she could accept anything from her brother-in-law?

After she finished wiping, Luis kissed her again. This time her response was a little more hesitant, naturally not as fervent as when she was climaxing.

But seeing her eyes closed, her face full of soft allure, was satisfaction enough for Luis. He kissed her for a long while, then caressed her breasts, giving her post-orgasmic affection.

Nancy had recovered somewhat, but kept her eyes shut in shame, slightly shielding her chest, her legs still clamped together vigilantly.

The System was right. The favorability meter was still low. If not for the genetic influence and her needing to borrow money creating this opportunity, there would have been no way to complete the task involving her legs.

"Big sister, why were you so surprised when I picked you up earlier?" Luis wanted to use a lighter topic to help her relax.

"You're so strong. I didn't expect you to lift me so easily." Nancy slowly opened her eyes.

"Has your brother-in-law never held you like that?" Luis deliberately teased her.

Nancy blushed, giving him a charming glare. "This is the first time anyone has held me like this, alright?"

Nancy was 175 cm tall, but her figure wasn't skinny like a stick; rather, she had a curvaceous, hourglass figure, so her weight was naturally not light.

Forget about Daniel, whose body was drained by drink and debauchery; even before his own body was enhanced, Luis felt he wouldn't have been able to lift her so effortlessly. Of course, he wouldn't be foolish enough to bring up a sensitive topic like weight.

"Really? Big sister is very light!" Luis, seeing her surprise and enjoyment of the princess carry, naturally complimented her further.

"Stop squeezing, it feels like you're making them sore." Nancy felt a little uneasy and scared because her brother-in-law's hands remained on her breasts, the faint pleasure stirring restless sensations in her body.

"I... I didn't want you to feel uncomfortable, but don't you push your luck." Seeing her put on a serious face and reach for her bra, Luis naturally wrapped his arm around her waist to stop her, joking, "Don't rush, big sister. Even if you put it back on, I'll just take it off again."

"Then stop touching me so much, it's ticklish!" Dealing with women required a bit of cheekiness. Nancy snorted proudly, then added, "It's not because of your money that I let you take liberties like this."

"I know!" Luis naturally played along, saying, "Big sister, it's my fault. You're too captivating, I couldn't control myself. I never thought about using the money to pressure you."

"Let's focus on the main matter first, otherwise, it'll be dawn soon."

He slept soundly and refreshingly on the sofa. At the final moment, he pulled his sister-in-law in for a goodbye kiss. Seeing her eyes grow increasingly tender and alluring, only then did Luis go downstairs.

"Ding... Mission 1 for the Tall, Sexy Sister-in-Law... Sister-in-Law's Thigh Job completed."

"Mission reward: 100,000 dollars in cash, one random blind box, 1 attribute point. All have been deposited into your account."

"Ding... Additional mission completed: Facial Cumshot on Sister-in-Law. Easter egg triggered: Obtained one blind box."

Luis, who had just lain down, was so thrilled he almost jumped up. Checking his phone, he saw the 100,000-dollar reward had already arrived. His current account balance was 417,000 dollars.

The number of blind boxes shown in his backpack was now four. Having never been so well-off before, Luis nearly cheered out loud. Most importantly, he still had that one attribute point.

"Ding... Tall, Sexy Sister-in-Law Mission 2: Sister-in-Law's Oral Sex, Blowjob... Mission reward: One blind box, 100,000 dollars prize money."

The new mission was issued immediately, leaving Luis utterly confused.

Normally, mission rewards should increase with each subsequent task, especially the cash prize which should double. But now it was stagnating, and even the reward of one attribute point was missing.

Could it be that his progress was too fast, and the System couldn't keep up?

After querying the System and getting no answer, Luis went to bed feeling somewhat puzzled. In that instant, he lost all desire to open the blind boxes.

He slept like a log, dead to the world. Feeling a faint kiss on his face, he knew his lovely wife Lily had left for work. Luis didn't even open his eyes, continuing his slumber.

Until cautious footsteps sounded by his ear again, along with voices talking:

"Big sister, where are you going?"

"Mom, keep your voice down, my brother-in-law is still sleeping. I need to go out for something."

Only then did Luis remember that she still needed to take the Cayenne in to get it sorted today. He really felt like getting up to see how his sister-in-law would act around him today, but if his mother-in-law was there, he lost interest.

"It's just, your mother-in-law is coming over tonight. About today's matter, give me a definite answer."

"Don't worry, Mom. I already said it was a scam call. Daniel is just making trouble for no reason."

"That bastard, he slapped me last time and just doesn't want to apologize. He's deliberately being unreasonable to try and muddy the waters. No way."

"Really?"

"Really, I'm heading out first."

Nancy's voice was light and breezy, the kind that was refreshing and carried a delicate softness. If she had been in her previous hysterical, irritable state, they'd probably be arguing again by now.

Last night, at the critical moment, Luis had honestly let her calculate the total. She honestly confessed all the money she owed. When they added it up, even she was shocked.

She remembered it was 21,500 dollars. After just a week, with penalties included, it was nearly 23,000 dollars.

The more Nancy thought about it, the more horrified she became. At this rate, even if she really had to sell her body, she wouldn't be able to pay off the snowballing interest. It was truly a vicious cycle designed to consume people whole without a trace.

At that moment, she was exceptionally vulnerable in Luis's arms. Her gaze grew even softer as she watched the man transfer 30,000 dollars.

Besides shame, there was also gratitude, because Luis added one more thing, "Big sister, you're not even carrying your bag, you must have sold it. Go buy a new, better one tomorrow. Don't let your mother-in-law laugh at you."

"And also, go get a facial, pamper yourself a little. Be radiant, let them see how well you're doing now."

The sister-in-law said "Okay," tacitly agreeing. She felt a little pleased that her brother-in-law was so attentive and observed things so carefully, never imagining that a powerful external plugin meant she had no privacy whatsoever.

Nancy was still thinking with shame, 'My brother-in-law noticed so many details, he must have had his eyes on my body for a long time...'

If it weren't for this particular family relationship, just based on how much he cared about her and his willingness to spend money so generously, she would be willing to be his lover, his mistress.

At that moment, Sister-in-Law Nancy: Favorability Meter 80%

The sound of the main door closing rang out. Luis turned over and continued sleeping. There were plenty of opportunities to be alone with his mother-in-law. Having ejaculated three times last night, his energy was depleted, and he needed proper rest.

His mother-in-law's voluptuous body was naturally full of allure, but he would hold back until a mission was issued. The top priority was figuring out how to increase her favorability meter.

Given their current relationship, his mother-in-law was like meat already in his mouth. He was just waiting for the moment he craved it most to devour her, that would be truly satisfying.
