"Thank you for calling me today. The kids were cute, and it was really fun."

"I feel like I'm falling behind."

"You both had a hard time. I'm glad you had fun."

After Sunday's volunteer work, it was getting dark in the evening.

"Seonha, can you give me your number? I'm going to ask you if I do it again next time."

Before she went away, he gave Yoon Siyeon his number. She is basically a very friendly girl, and because she was dealing with volunteer work, he didn't care, as if she knew Kim Jihoon would do the same.

However, even though she said that, she has only been dating for 3 days, so it is reasonable for Yoon Siyeon to be considerate of her boyfriend.

Name: Yoon Siyeon

Age: 21

Number of sexes: 0

Likeability: 65

Sexual desire: 64

Applicable cards: [SR: Seed of Immorality] [R: Chastity before marriage]

The likeability and sexual desire I posted along with the two cards naturally led me to pick a number.

In fact, if I work hard enough, I might be able to remove it even after I raise it to this point without using the app's power.

However, if you increase your sexual desire to this level, your basic sexual desire will be maintained to some extent, and there is a possibility that you will release it to your boyfriend.

[R: Chastity before marriage]

[The person to whom the card is applied is not allowed to touch the target specified by the user (kiss or sex) more than that. [The water level can be set by the user.]

Yoon Siyeon's premarital chastity card will stop any skinship. She had wanted to do more than just have sex at first, but she refused to allow kissing after learning that they were merely holding hands.

'Thank you, Jihoon.'

Let's grab dinner together the next time. If only we had more time today. "Goodbye, Seonha!" 

"Don't be late for tomorrow's lecture."

Jihoon's greeting was a touchy one since he often met her in college, but Yoon Siyeon's farewell was filled with goodwill. He feels really sad that they can't eat together today.

"Okay. Have fun with your date. See you next time."

He sent the two off with a beaming smile. All he had to do was take his time and wait, since Seed of Immorality was a card that required some time anyway.

He was very excited to see in what form it would return to him.

***

[System: Acquire 120 points]

The points earned today were higher than yesterday. The time was a little shorter, and I was by Minwoo's side most of the time, so I was relatively more comfortable.

Although it looked strange, it was understandable.

If you were asked whether you would rather do physical labor holding 10 people or take care of a child with a mild intellectual disability for 8 hours, 9 times out of 10, you would choose physical labor.

Even if the child is not disabled, it is not easy to stay by her child's side all the time.

'Anyway, thank you for giving me a lot.'

He then excitedly walked back home to draw the gacha, eager to find out what he would get.

"Ah, hello~~"

"Sister Gayoung??"

Gayoung Noona was standing outside my house. She was holding Lock containers in her hands that held food.

"Thank God~ I was going to give you some side dishes, but you weren't home, so I thought I should come back later."

"Wow, is it a side dish? Just a moment! I'll open the door right away."

He was unaware that it would arrive in this manner when she promised to give it to him.

'We have only exchanged greetings for a week.'

'Within a week, this older noona's favorability rating exceeded that of Kim Jihoon, my best friend in college, who had a rating of 52.'

I quickly opened the door and threw the bag I was carrying into the house. After that, I turned around to get the side dish container, and the older sister was sticking her head out and looking around the house.

Since I had nothing to hide, I turned my body slightly to make it easier for her to see.

"Seonha lives a neat and tidy life? It's amazing~"

"These are the basics."

The older sister came all the way into the shoe closet and faced me, giggling and holding out a food container.

With a happy heart, I mixed a spoonful of Sasim into it and held the container while secretly touching her finger.

And the moment my finger touched her.

"Wow!"

-Tung! Wow! Huhhhh!

She dropped the food and key on the floor. Fortunately, the seal was secure, so the contents did not spill.

I quickly bent down, picked up the container, and smiled.

'The stimulant effect is certain.'

Actually, it wasn't 100% intentional.

I was literally just trying to get a taste of my fingertips out of selfish interest, but seeing the intense reaction, it seemed like the stimulant card was playing a big role.

Other people might not know this, but this older sister basically had a very high sex drive.

Of course, Gayoung, who had no way of knowing that, was extremely sorry and panicked.

"I'm sorry. My hand suddenly started tickling, and I got started."

"No, sister. I'm sorry I accidentally touched you."

Instead of showing my joy, I piled the containers on the floor and apologized with a shameless face.

Then the older sister broke into a cold sweat and was busy making excuses.

"Oh, no~ I'm just a little surprised? Little brother, can you give me your hand? Sister, I don't mind this kind of thing."

"You don't have to overdo it."

"Are you really saying it's not true? Now, look at this!"

As he says, she holds one of my hands with both hands.

"Ah… "

And that's when the sister's eyes clouded up a little. She exclaimed with excitement and gripped my hand tightly, refusing to let go.

I quietly watched it. Not saying anything, as if I never existed from the beginning.

She held my hand quietly for a moment, and then she began to gently play with it.

-Rub... rub…

Even though she was a housewife in her early 30s, Gayoung's hands were clean and without any blemishes, and they gave a pleasant touch to my right hand, with a slight coldness.

Moreover, that touch even contained something strange. It was as if her uncontrollable sexual desire was mixed in.

"Noona?"

"…Huh? Oh, that's right! Look, you're fine, right~?"

"I thought my sister didn't like me... I'm glad. I guess you were surprised because I tend to have warm hands."

"So… Y-Yes. I also think it's because it was warm."

Since Yunho's husband was at home anyway, it wasn't like we were going to have sex right now, and I thought it would just be a tantalizing experience, so I stopped. Then, the older sister was startled, took her hand away, and insisted on her innocence.

Her face turned bright red, and I laughed inside at the way she spoke as if nothing had happened.

As I was about to say thank you for the food and go in, an image of a kind-hearted noona loitering in front of my door, appeared in my mind.

"Noona. Can you tell me your number? I'll text you later when I return the container."

"Uh, yes. That's right. Here, take it."

When I told her that I needed her phone number to return the container, she put the number on my phone as if she had been waiting for this moment.

"Thank you once again for the food. Noona."

"Hehe, enjoy it."

Since it was roughly sorted out, I quickly said thank you and ended the situation.

Gayoung went home right away, and I roughly put the side dishes in the refrigerator and sat on the bed to use my smartphone.

"Gacha, gacha, gacha!"

'I wanted to fuck Gayoung Noona.'

If I didn't come up with anything useful this time, I was thinking of just throwing in the favorability and libido cards or using the threat card.

With that promise in mind, I turned on the gacha. In a hurry, I pressed the skip button for the first time and checked the 10 cards.

[N:: Likeability] x 3 [N:: sexual desire] X 3

[R: Odor]

causes a faint odor from the target's body. It will remain in that state until the card is removed.

[SR: Mite, take care of it.]

makes the user feel maternal love. It can be expressed in various ways depending on likeability, sexual desire, mood, and situation.

[SR: Against violence]

The object to which the card is applied can never pose a physical threat to the user.

[SR: Sexual desire destroys love]

If the user's sexual desire is higher than the target's liking for others, sexual desire takes precedence over all ethical aspects.

6 normal cards, 1 R, and 3 SR.

It was an ideal configuration. I also really liked the cards that came out. It's good for sweating, and more than anything, I finally got some cards to use for Gayoung.

What I wanted was for Gayoung to naturally touch me, rather than for me to touch her. Preferably based on sexual desire, as an older person.

There is already an absurdity in the word 'naturally' in the sense of using an app, but without it, the story wouldn't start in the first place, so let's move on.

In that sense, [SR: Sexual desire destroys love] The card was perfect. As if I gave it to Gayoung on purpose just so I could fuck it.

Wouldn't it be more perfect if the motherly love card supported it?

"Damn it, I believed I can do it!!!"

I couldn't help but cheer.

Even before I got this app, how much did I internally endure while looking at that married woman showing off her big breasts and buttocks every time I saw her?

However, since I was a normal person with a reasonable sense of reason, I just didn't want to pay attention to Gayoung, who already had someone else.

But it is different now that there is an app.

I could do it at any time if I forced it, and even if that wasn't the case, I could adjust the situation as I wanted.

I can have sex with my sister, Gayoung.

Name: Gayoung

Age: 32

Number of sexes: 178

Likeability: 61

Sexual desire: 76

Applicable cards:

"Do you want to see this?"

When I uploaded my sister's information to use the card, I was able to see that her favorability and sexual desire for me had increased.

Maybe it's because she looked good at me picking up trash or doing volunteer work, and because she touched my hand a little while ago and her body became sensitive.

I smiled and immediately inserted the card.

Name: Gayoung

Age: 32

Number of sexes: 178

Likeability: 71

Sexual desire: 76

Application card: [SR: Mite, take care of it] [SR: Sexual desire destroys love]

Other than the SR cards, I only used one more affinity card, and I didn't touch on sexual desire right now.

Yunho is at home, so I can't invite Gayoung here and get into a sex mood. I was planning to take advantage of the time when the two of us were alone and increase the likeability to 90 when her husband was away.

Gayoung Noona's liking for her husband, Yunho Hyung, is very high, so if I don't raise it to that level, she will somehow hold on to the opposite sex.

I calmed down, opened the store, and then [R: increased physical strength] I bought a card and added it to my status.

Name: Lee Seonha

Age: 21

Number of sexes: 1

points: 21p

Cumulative advance points required to reach the next level: 279

Applicable cards: [SR: Entire body stimulant ON] [R: stamina increase]

To be honest, I thought that improving physical strength was a very ambiguous card, but it seemed to be more useful than I thought, including when I had sex with Seol and while doing volunteer work yesterday and today.

Surprisingly, I felt this card had made me stronger and more handsome.

Even though I cleaned for such a long time yesterday, my body was a little tired, and I didn't even have any muscle pain. Even though I have a lot of stamina, it was surprising, even considering that.

It is a card worth using for about 20 points.

"It's fun to use points."

I ran the gacha and distributed a lot of cards, so all that was left was when I would have sex with Gayoung.

"The best time is when Yunho comes to work, but... I'll be screwed if I skip general physics tomorrow in college."

I had already escaped once while experimenting with the app, so it was too dangerous to go any further. The professor is a strict person.

First of all, I'll definitely go to the lecture until tomorrow, and from Tuesday onwards, I'll have to somehow make a place just for the two of us.

Just like Seol, when he imagined Gayoung being fucked and moaning while being fucked by him, his cock hardened.

"Gayoung, what are you doing now? It's usually time to take a shower. Huh?"

Still, I felt regretful that I couldn't have sex right now, and without even thinking about it, I looked up Gayoung's information again.

Name: Gayoung

Age: 32

Number of sexes: 178

Likeability: 71

Sexual desire: 79

Application card: [SR: Mite, take care of it] [SR: Sexual desire destroys love]

He noticed that her sexual drive had increased again. As soon as he saw it, he suddenly felt a sense of possibility, and immediately used the [R: Voyeurism] card on her. 

Then what appeared on the smartphone screen was.

[Sigh. Yes.]

It was Gayoung's masturbating while sitting on a bathroom chair in the bathroom.
