"Where do you get so many tricks from?"
Ruth had even given oral sex for the first time just last night, so it was understandable that while she had heard of and talked about titfucking, she had never actually tried it.
Luis suddenly found his father-in-law Arthur particularly endearing. The man was old-fashioned, conservative, and favored sons over daughters. Forget anything more advancedâeven oral sex was a bizarre concept to him.
To think a mother-in-law with such enormous breasts had never experienced titfuckingâit was practically a crime against nature. Such waste was downright shameful.
"Mom, itâs about time."
He had originally intended to smoothly complete the task, but seeing his mother-in-lawâs anxious demeanor, he knew her mind was elsewhere.
Even if he forced the next task, the experience would be poor. So Luis sat up proactively, gently stroking his mother-in-lawâs hair as he said, "Next time. Sleep well tonightâI wonât come over."
"Then what about... it?"
Ruth asked, somewhat ashamed, as she stroked his cock.
Even as she spoke, she kept glancing at the time. Luis lost interest in her distracted state and didnât want to press her further.
"Donât worry about it. When your daughter gets back, she can take over."
"Then you go out first. Mom needs to change clothes."
"Mom, just change. I want to watch."
Under her son-in-lawâs gaze, Ruth shamefully took off her nightgown, her full breasts swaying as she put on fresh clothes. The entire process was accompanied by her son-in-lawâs groping hands.
After hugging his beautiful mother-in-law and sharing a passionate, deep kiss at the door, Luis patted her butt and let her leave.
Back in his room, Luis opened the System interface. In this world full of code, his backpack finally didnât seem quite so pitiful anymore.
Inside were: Aphrodisiac Incense (male), three blind boxes, and one attribute point.
Luis first considered the attribute point. His status bar still only showed two options: Charm and Body, proving the System deemed other attributes unnecessary fluff.
The only lit-up label was: Innate Mastery of Spanish (including dialects).
Luis pondered where to allocate this attribute point. His current physical condition seemed fineâhis sexual stamina was more than sufficient.
In fact, he was almost troubled by how long he lasted. It took him half an hour to ejaculate every time, and such prolonged sessions risked complications. It was a Versailles-level problem for Luis.
"Ding... System notification: Corresponding gene located for knockout screening. Delayed ejaculation issue resolved."
Luis was momentarily speechless. Delayed ejaculation was actually a disorder? Human genetics were truly fascinating.
"Recommendation: Host should allocate attribute point to Body to further improve physical metrics. This will aid in expanding beneficial gene effects and allow more flexible development of sexual capabilities."
Sexual capabilities... flexible development... Well, Luis couldnât refuse phrasing like that.
It was like offering beauty treatments to women and virility enhancers to menâan appeal that never failed.
His Body attribute was already at 7, the level of a robust athlete. Without hesitation, Luis added the new point, raising it to 8.
Instantly, his body was wracked with tearing pain and a bloated, balloon-like sensation. Every part of him ached, right down to his bones.
Agonized, Luis felt as though his internal organs were rearranging themselves to adapt to his new form. A wave of dizziness overwhelmed him, and he bolted uncontrollably to the bathroom.
He slammed the door shut and vomited violently, as if emptying his very stomach. It felt like he was expelling more than just food.
Then came the intestinal crampsâhis large intestine convulsed like the African savannah under a stampede of elephants. The world spun nauseatingly around him.
The diarrhea nearly debilitated him. Simultaneously, his pores dilated painfully, secreting a dark, foul-smelling substance that reeked horrifically.
The stench nearly made Luis pass out. After what felt like an eternity of tortureâalmost a full hourâthe discomfort gradually subsided.
"Ding... Body attribute 8. Adaptation to genetic modification progress complete."
"Ding... Maintenance of carbon-based life form finalized. Plastics, heavy metals, chemical factors, and other external contaminants have been purged."
The upgrade and detoxification took an hour. Every second felt like a year of torment. When it was finally over, Luis let out a massive sigh of relief.
He stretched his stiff limbs, opened the window to air out the roomâthe expelled toxins were unbearably foulâand examined himself in the mirror while showering.
His facial features were sharper, more defined, with a roguish handsomeness now evident.
He seemed slightly taller, now clearly over 180cm. The sensation of his bones lengthening and thickening was disorienting.
His skin tone was unchanged, and his build appeared similarâstill lean, but with dramatically more pronounced muscle definition.
When he clenched his fist, the muscles in his arm bulged distinctly, hard and well-defined.
His chest, previously undertrained, now had a squared, slightly bulging shape. His shoulders seemed broader, better proportioned.
At level 7, his abs had been hidden under a layer of fatâpalpable but not visible. Now a six-pack was clearly visible.
He was the type who looked slim clothed but ripped undressedâa natural, healthy musculature, not the artificial bulk of protein powder.
When the Wood sisters returned, Luis was doing push-ups in the living room. Despite his empty stomach, he was drenched in sweat, moving with rapid intensity.
"Youâre back. Honey, sit down first. Be good and drink your soup later."
His hair was soaked. Luis smiled gently at them and continued exercising. His body, glistening with sweat, showcased every muscle contraction with striking visual impact.
It wasnât that Luis was showing offâafter the physical adjustment, his slightly increased height and broader shoulders required exercise to help him adapt.
Even though he felt healthy, heâd almost tumbled down the stairs earlier because his sense of balance felt different from before.
Nancyâs eyes lit up, and she teased playfully, "Brother in law, I never noticed before that you had such an impressive physique~"
"Lily, you are truly blessed~"
Lilyâs face was flushed with a happy blush. She bit her lip as she gazed at her husbandâs well defined muscle lines, feeling her underwear become subtly damp.
After his physical attributes ascended to a higher level, the aura Luis emitted when excited affected them even more intensely. Nancy, who was unrelated, merely blushed and felt her heart race. But for the pregnant Lily, it was practically an aphrodisiac, a dual feast for both vision and smell.
The two sisters had bought a huge amount of items, big and small. They placed their shopping on the floor, sat on the sofa, and complained about being exhausted, yet their eyes remained fixed intently on Luis.
Luis even felt a bit unnerved by his wifeâs devouring gaze. His wife was expressing her desires so blatantly through her eyes. The raw hunger in her stare was so intense that it made even Luis, a man perpetually hungry for lust, feel somewhat embarrassed.
Luis also stopped his strenuous, sweat drenched workout. He stood up and said with a smile, "Wife, Iâm going back to the room to do some sit ups. You and big sister should drink the soup on the table."
The ginseng and black chicken soup on the table was fragrant and delicious. Nancy also drank it happily and joked, "Stinky Lily, I canât believe youâre enjoying such good fortune. My brother in lawâs abs look so touchable, just a few strokes would be satisfying."
"You can touch them if you want. Iâm not stingy," Lily replied with a smug smile.
Although subtle changes had occurred in Luisâs body, they werenât noticeable without meticulous observation. As his intimate partner, Lily didnât harbor many doubts. To her, her husbandâs body had simply become more alluring and felt more captivating than before. The reason for this change was completely unimportant.
The two sisters shared a rare moment of deep sisterly affection. They chatted and organized their newly bought clothes until late into the night before finally returning to their respective rooms.
"Husband, it feels like itâs gotten thicker~"
In the master bedroom, his wife Lily lay completely naked, crouched between her husbandâs legs.
After finishing licking his abs, she now took his cock into her mouth, sucking and playing with it. The wet, slurping sounds of her taking him in and out filled the room, her face a picture of utter intoxication.
"Wife, itâs so late and you still donât want to sleep? Arenât you tired after shopping all night?"
"I am tired, but smelling your dickâs scent just energizes me," Lily said.
As she spoke, she held his penis, licking it from base to tip for a while before moving down to lick his testicles, her expression so enraptured it was as if she were bewitched.
"Husband, I asked the doctor... The doctor said even if we do it from behind, itâs best to wait until after three months."
"The fetus isnât stable yet. I need to avoid excessive excitement and stressful stimulation."
Luis smiled and stroked her face, saying, "Then Iâll just wait a little longer~"
"Husband, your phone is ringing."
His considerate wife incredibly handed the phone from the bedside table to Luis before once again bending down, taking his cock into her mouth, and beginning to suck it.
Luis saw it was a message from his sister in law, Nancy: "Is Lily asleep? I have something to tell you. Can you come over?"
Luis thought for a moment, then directly recorded a video of his wife giving him a blowjob and sent it over. After a while, Nancy replied with a single sentence: "Then letâs talk about it tomorrow."
Last time, his intimacy with his wife had been stumbled upon by his sister in law. This time, Luis sending such a video outright was already tantamount to teasing. After the dayâs stimuli, their relationship had unconsciously advanced a step further.
