Widow Liu Min, not yet forty, came to the city with her twenty-one-year-old son Xiaoliang and daughter Xiaohui to make a living, and was taken in by the company powerhouse Lu Lin to work as a nanny. In the hot summer, Lu Lin was used to walking around the house wearing only sexy lingerie, while her husband, short and impotent, could only vent through video discs. Adult Xiaoliang, under the influence of drugs and daily stimulation, found his lust impossible to quell. After accidentally glimpsing Lu Lin's private parts without underwear, the forbidden fire was completely ignited. Liu Min's long-repressed body also began to awaken, and under the same roof the several of them gradually slid into an uncontrollable entanglement of desire.

Liu Min was a widow. After her husband died, she took her twenty-one-year-old son Xiao Liang and her equally twenty-one-year-old daughter Xiao Hui and left the village for the city. That year she was not yet forty; her looks still retained the beauty widely recognized in the village, her skin delicate, her waist supple, only her brows and eyes carrying a bit more maturity gained through the hardships of life.

It's not easy for a woman without any special skills to get by in the city with two grown children. Renting a place, eating, finding a job—everything is difficult. Just when she was almost at her breaking point, she met Lü Lin.

Lü Lin was around forty years old and was the general manager of a company. She had an oval face, a cherry-small mouth, and between her brows and eyes there was the charm unique to a mature married woman; her silver-bell-like voice was enough to make one’s heart soften. The company was founded by her and her husband together. Her husband was listed only in name as the legal representative; she was the one truly in charge. The male coworkers in the company privately treated her as an object of fantasy, but in person no one dared reveal even the slightest bit. Lü Lin managed strictly; if subordinates made even a small mistake, they would be scolded until they could not hold their heads up. At best their wages would be docked; at worst they would be fired on the spot.

But when she got home, it was different. Her husband often traveled on business, and the two of them could scarcely see each other a few times a month. Every time she pushed open the front door and faced the empty living room, Lü Lin would feel a deep loneliness. The house was several hundred square meters, and when it got messy she couldn’t be bothered to clean it. Her husband suggested several times hiring someone to tidy up, but whenever she got busy she forgot about it.

The company’s business entered the off-season, and the weather gradually turned hot as well. So Lulin went alone to the labor market, hoping to find a live-in nanny. Before even reaching the entrance, she saw Liu Min looking for work with her whole family in tow. After chatting for a few words, Lulin felt sympathy and also found her compatible. Learning that Liu Min still had no place to live and that her husband had died early, she directly suggested, “My house has several empty rooms. Bring your children and come live here. That way there’ll be someone to talk to, and the house can be kept clean too—killing two birds with one stone.”

And so it was decided. Liu Min became the live-in nanny at Lü Lin's house, eating and living there. Over the next few months, the house was kept spotless, and the two became close sisters who shared everything. Lü Lin's husband also breathed a sigh of relief—with such an honest and reliable person keeping his wife company, he could feel more at ease when on business trips. As for the occasional fleeting improper thoughts, he just dismissed them as normal male fantasies.

During the off-season, her husband didn't need to travel far and stayed home every day watching TV and DVDs. The family was already well-off, and with both idle, flirtatious banter was inevitable. Liu Min turned a blind eye, pretending not to see. But Xiaoliang and Xiaohui were already twenty-one, raised in the countryside, and still blushed at such scenes. Lü Lin and her husband, however, didn't mind at all, acting as if no one was home.

The weather was getting hotter and hotter. At home, Lu Lin didn’t even wear a coat anymore, only walking around the house in thin, sexy underwear. Her full breasts were practically about to spill out of her bra, and her bright red nipples and black pubic hair could be faintly seen through the fabric. Even Liu Min blushed and her heart raced at the sight, let alone her two children. Xiao Liang hid in his room all day and rarely came out, while Xiao Hui, though a girl, would occasionally let her eyes drift toward Lu Lin.

At first Lü Lin’s husband was still dressed neatly, but as the temperature rose, he wore less and less, and in the end only a tank top and a pair of briefs remained. Liu Min accidentally discovered that his thing was not big, and could even be said to be rather small. It was noon, and the whole family was napping. Liu Min got thirsty and went to pour some water, only to find that the TV in the living room was still on and only Lü Lin’s husband was sitting there alone. On the screen was explicit content; his penis was already erect, looking to be only about two-thirds the size of her late husband’s.

Liu Min had not touched a man for almost a year. A sudden wave of heat surged in her lower abdomen. The TV suddenly cut to a close-up— the foreigner’s penis was frighteningly thick, the image so clear it looked real. It was the first time Liu Min had seen the genitals of a man other than her husband, and even more so the first time she realized her underwear was already soaked. She clenched her legs together and carefully retreated to her own room. The two children were sleeping soundly. She lay on the bed but could not fall asleep at all; her mind was full of the scene from just now, imagining what it would feel like to be filled by something so thick.

She thought of Lu Lin again. With Lu Lin’s looks, shouldn’t she be able to satisfy her husband? In fact, she did not know. How could Lu Lin’s husband not want to properly enjoy his wife? It was just that his desires exceeded his abilities. What he had was short and small, and no matter how many medicines he took, nothing worked. Every time they made love, he could only barely satisfy Lu Lin with mouth and hands. For him, that was a humiliation. He could feel his wife’s dissatisfaction, yet was powerless to do anything. Two mature and beautiful women in the family, yet he himself could only look and not truly enjoy them; this torment went on day after day.

Lü Lin woke up and found her lower body wet and sticky. Another erotic dream. She sighed, thinking that perhaps in this lifetime she would never again feel the fullness of being completely filled by a thick, long cock. After washing her face, she saw Liu Min busying herself in the kitchen and felt lucky to have found such a good nanny. She walked into the kitchen and happened to see Xiao Liang and Xiao Hui both helping pick over vegetables. Lü Lin also squatted down to help. Perhaps because she had just woken up and was still groggy, she forgot that she wasn’t wearing panties. Her short skirt could hardly cover her snow-white thighs and buttocks, and her pink labia and black pubic hair were facing Xiao Liang’s direction.

Twenty-one-year-old Xiaoliang was at the age of peak desire. After coming to Lü Lin’s home, he ate well and was well supplemented. Liu Min, unable to read many words, treated the virility-enhancing supplements that Lü Lin’s husband had bought but couldn’t use as ordinary tonics, and often gave them to the two children to eat. Xiaoliang was naturally strong to begin with, and with those things added, his desire became impossible to control. He could only vent through masturbation. Over time, that thing grew thick and long, and even in hot weather he didn’t dare wear shorts.

At this moment, seeing Lü Lin's completely exposed private parts up close, Xiao Liang felt his lower body instantly harden painfully, tenting his pants high. Lü Lin was startled, thinking he had something hidden in his trousers. Xiao Liang's face turned beet red, and he lowered his head, not daring to move. Following his expression and the constantly twitching outline in his crotch, Lü Lin immediately understood. Looking down and seeing she was wearing nothing below, her heart skipped a beat. Fortunately, Liu Min and Xiao Hui had their backs to them at the stove. Lü Lin quickly stood up, pulled her skirt down, and walked out of the kitchen with a flushed face.

Xiao Liang was so scared that his thing went soft, thinking it was over, Auntie Lü would definitely kick them out.

"Dinner is ready!" Liu Min called out, and all five people came to the dining table. After Lü Lin and her husband sat down, Xiao Liang clearly felt that Lü Lin's gaze toward him was a little strange. His mind was in a mess; he hurriedly finished eating and went back to his room. Lying on the bed, his head was full of that scene from the afternoon — Lü Lin's pink private parts, her snow-white butt. Before he knew it, he was hard again, and very hard at that; no matter how he covered it with the blanket, it couldn't be hidden, and it kept twitching.

At that moment, footsteps sounded at the door. Xiao Liang quickly turned on his side, facing away from the door. It was Liu Min who entered. She felt her son had been acting strange these past two days and wanted to check on him. As soon as she pushed the door open a crack, she saw the large, raised lump on her son's bed. Liu Min's heart skipped a beat, but she didn't make a sound. She gently closed the door and retreated.

She leaned against the corridor wall, her breathing somewhat ragged. Her son was already twenty-one; it was normal for him to have a reaction, but the shape just now... was much larger than she remembered her husband's. Liu Min suddenly felt her lower body becoming wet again. She forced herself to calm down and returned to the kitchen to continue cleaning up.

In the evening, Lü Lin came out of the shower wrapped only in a towel. Her husband was already in the bedroom watching a DVD, with the door closed. Liu Min was folding clothes in the living room, and Xiao Hui had returned to her own room. Xiao Liang, however, came out again to get water because he was thirsty. The two of them bumped into each other at the kitchen entrance.

Lü Lin’s bath towel barely covered the important parts, leaving her full cleavage and long legs completely visible. Xiao Liang’s gaze could not help drifting downward. Lü Lin did not immediately avoid it, but instead gave a light smile and lowered her voice: “About this afternoon... don’t take it to heart. Auntie isn’t blaming you.”

Xiao Liang flushed red, wanting to escape. Lü Lin suddenly reached out, gently touching the already bulging area through his pants. Xiao Liang trembled all over, almost crying out. Lü Lin's fingers lingered for two seconds before withdrawing, her expression complex: 'So big... much bigger than your Uncle Lü's.'

After saying that, she went into the bedroom. Xiao Liang stood in place, his pants painfully hard, with fluid already seeping from the tip.

That night, Xiao Liang couldn't sleep at all. He heard faint, suppressed moans from Lü Lin's room next door, along with a man's low voice. He couldn't help but press his ear against the wall. He could tell Lü Lin wasn't truly satisfied; in the end, her husband finished her off with his mouth. Xiao Liang's hand involuntarily slipped into his pants, grasping his own thick, hard member, imagining if it were him instead...

Meanwhile, Liu Min was not asleep either. She heard the faint sounds from her son's room and knew what he was doing. Somehow, her fingers had also slipped into her underwear. Her body, untouched for more than a year, was extremely sensitive; just rubbing it a few times left her soaking wet. She bit her lip, imagining the scenes she had seen this afternoon, and soon came once.

Starting the next day, the atmosphere at home became subtle.

Lü Lin began intentionally or unintentionally walking back and forth in front of Xiao Liang, sometimes deliberately bending over so that the view under her short skirt flashed by. Xiao Liang tried his best to avoid her, but the body’s reaction could not lie. Liu Min saw it all and felt both worried and an indescribable stirring.

Finally, one afternoon, the husband went out on business, Xiao Hui went to a classmate's house, leaving only Lü Lin, Liu Min, and Xiao Liang at home.

Lü Lin called Xiao Liang to her room and closed the door. She was wearing only a semi-transparent nightgown, with nothing underneath. Xiao Liang stood at the door, too afraid to go in. Lü Lin walked up to him and directly pulled down his pants zipper. That thick, long cock sprang out, almost hitting her hand. Lü Lin’s breathing clearly became irregular: “It’s really that big... Auntie wants to try it.”

She didn't give Xiao Liang a chance to refuse, directly kneeling down and taking him into her mouth. Xiao Liang had never experienced this before; within a few strokes, he groaned and came in her mouth. Lü Lin, however, wasn't angry. Instead, she swallowed and her eyes grew even hotter: 'Can you get hard again?'

Xiao Liang nodded. Lü Lin took off her nightgown, lay completely naked on the bed, spreading her legs. Xiao Liang climbed on top, aimed at the moist entrance, and squeezed in bit by bit. Lü Lin let out a long, satisfied sigh, hugging his back tightly with both hands: 'Yes... just like that... come all the way in...'

Xiao Liang was completely driven by instinct, starting to thrust vigorously. Lü Lin's moans grew louder, her ample breasts shaking violently. She quickly climaxed once, her inner walls spasming and sucking. Xiao Liang was still hard, continuing. When he ejaculated inside her the second time, Lü Lin's legs were already too weak to lift.

Actually, Liu Min had been standing outside the door all along. She heard everything, and her panties were soaked through. When Xiaoliang came out of Lu Lin's room, the two faced each other in the corridor. Liu Min didn't curse at him, she just said softly, "Go back to your room."

Xiao Liang followed his mother into his room. As soon as the door closed, Liu Min reached out and grasped her son's thing, still carrying Lü Lin's warmth. She herself knelt down, clumsily but earnestly taking it into her mouth. Xiao Liang held his mother's head, quickly hardening again. Liu Min took off her clothes, straddled him, and slowly sat all the way down. Mother and son did it like that in the room. Liu Min's body, suppressed for too long, was frighteningly sensitive; she climaxed after just a few thrusts. Xiao Liang held her waist, thrusting forcefully, finally ejaculating deep inside.

From that day on, everything at home completely changed.

During the day, Lü Lin would find opportunities to call Xiao Liang into her room, having him enter from behind, or sitting at the dressing table watching in the mirror as they did it. At night, Liu Min would slip into her son's room or call him to her own bed. Xiao Hui gradually began to notice something was off, but when she one day stumbled upon her mother being pressed onto the bed by her brother, she didn't immediately react; instead, she stood at the door and watched for a long time.

Later Xiaohui also joined in. First she was seduced by Lü Lin, letting Xiaoliang take care of two women at the same time. Later, Liu Min also accepted her daughter's participation. The relationships among the few of them became completely entangled.

Lü Lin’s husband remained completely in the dark. He only felt that his wife had recently been in a better mood and her body had become more and more supple, but he did not know that what truly filled her was the twenty-one-year-old young man in the house.

Summer passed little by little in desire. Day and night, muffled moans and the sounds of bodies colliding could echo through the house. Liu Min, Lv Lin, Xiao Liang, and Xiao Hui—four adults under the same roof—turned the most forbidden relationship into everyday life.

And all of this was just the beginning.

During the hottest days of summer, the whole house almost became a breeding ground for desire.

Lü Lin’s husband still went on business trips every few days, leaving for four or five days at a time. Every time he had barely left, the atmosphere at home changed completely. The curtains were drawn tightly, the air conditioner was turned very low, yet several people were often drenched in sweat.

Xiao Liang had completely adapted to this kind of life. He no longer avoided it, even started taking initiative. In the morning when Liu Min was making breakfast in the kitchen, he would press up against her from behind, pushing against the seam of his mother's buttocks through her thin house pants, his hands reaching under her armpits to knead those still perky breasts. Liu Min initially would softly scold, 'Don't mess around, Hui Hui is still here,' but her body honestly leaned back, after grinding a few times, she would pull her pants down to her knees herself, letting her son enter directly from behind.

Often, while stir-frying, she would be thrust into so hard that her hands trembled. The sound of the spatula hitting the wok masked the suppressed wet noises. After Xiao Liang came inside, Liu Min would clamp her legs together to keep the semen in, continuing to cook as if nothing had happened. By the time Xiao Hui and Lü Lin came out, a hot breakfast was already on the table, with only the occasional dampness between Liu Min's legs hinting at what had just happened.

Lü Lin was even more direct.

During the day, she would call Xiao Liang into the master bedroom and lock the door. Sometimes she would make him lie on the bed and straddle him, slowly riding him up and down; sometimes she would let him enter from behind, while she braced both hands against the floor-to-ceiling window, looking at the empty residential road below as her breasts rippled with each thrust. She especially liked being ejaculated inside at the moment of climax, then going downstairs in her original clothes and chatting with Liu Min as if nothing had happened, while still holding the young man’s essence inside her body.

Xiaohui's joining made the situation even more chaotic.

At first she only peeked. One night she pretended to be asleep, but heard the familiar sound of the bed board and suppressed moans from her mother's room next door. She quietly pushed open the crack in the door and saw Liu Min being pressed under her brother, her legs spread wide, the joining area a muddy mess. Xiao Liang went deep and hard with every thrust, Liu Min's breasts swaying continuously with the impact, her mouth intermittently calling out her son's name.

Xiaohui watched for a long time, her panties already soaked through.

At noon the next day, she deliberately walked into the bathroom while Lü Lin was showering. In the steamy mist, she saw Lü Lin's voluptuous body and the white residue not fully wiped from her inner thighs. Lü Lin didn't cover up; instead, she smiled and asked: 'Want some too?'

Xiaohui nodded, her face flushed.

Lü Lin pulled her into her own room, locked the door behind her, and then called Xiao Liang over. When Xiao Liang came in, he saw his younger sister sitting naked at the bedside and froze for a moment, then immediately understood. Lü Lin had Xiao Hui lie down, spread her legs, and lowered her head to use her lips and tongue to help her with foreplay. Xiao Hui had never been treated like this before, and in just a few minutes she trembled into an orgasm once. Immediately after, Xiao Liang held his already hard and swollen cock and aimed it at that tight entrance of his sister’s, slowly pushing inside.

Xiaohui gasped in pain but stubbornly bit her lower lip to keep from crying out. Lü Lin held her hand beside her and whispered, 'Bear with it, it'll feel better in a moment.'

It was indeed as she said. After Xiao Liang fully entered and began thrusting, the pain gradually gave way to an unfamiliar sense of fullness. Xiaohui's inner walls tightly clenched around her brother's member, yet tears unknowingly streamed down her face—not from pain, but from a kind of utterly debauched shame and pleasure.

From that day on, Xiao Hui also became a regular participant.

Sometimes it's Lü Lin and Xiao Hui serving Xiao Liang together, one with mouth, one with below; sometimes it's Liu Min and her daughter being used by their son simultaneously, mother and daughter lying face to face, legs intertwined, letting Xiao Liang take turns entering. More often, the four squeeze onto the master bed, limbs entwined, unclear whose hand is caressing whom, whose lips are pressed to whose skin.

At first, Liu Min still felt a strong sense of unease and guilt about her daughter’s involvement, but when she personally saw Xiao Hui’s tense toes and flushed cheeks at the height of orgasm, that unease was slowly replaced by a more complicated emotion. She would even reach out to rub Xiao Hui’s breasts when Xiao Liang entered her daughter, or lower her head to lick the fluid overflowing from the place where the two were joined.

Once a taboo is broken, it can never return to how it was.

The days when Lü Lin’s husband occasionally came home became the most tormenting and most exciting period.

On the surface, everything was normal. Liu Min continued with household chores, Xiao Liang and Xiao Hui would deliberately avoid each other, and Lü Lin also restrained herself considerably. But as soon as her husband fell asleep or went into the study to handle documents, the others would quickly find an opportunity.

Once when her husband was watching TV in the living room, Lü Lin excused herself to the kitchen to get water, but in the kitchen, Xiao Liang entered her directly from behind. She had to bite her own hand hard to keep her moans from leaking out. Xiao Liang thrust fast and deep, hitting the deepest spot each time, and deliberately whispered in her ear, 'Aunt Lü, it's so wet and hot inside... Can Uncle's little thing make you feel this good?'

Lü Lin was so ashamed and angry that she almost cried, yet her body betrayed her by continuing to contract, and in the end when Xiao Liang came in, her legs went weak and she nearly couldn’t stand. When she tidied up her clothes and walked out, there was still an abnormal flush on her face. Her husband looked up at her and assumed it was just because the weather was too hot.

Once again, when her husband was taking his afternoon nap, Liu Min called both Xiaoliang and Xiaohui into her room. The three of them squeezed onto the single bed, though none of them dared move too much. Xiaoliang went in from behind their mother first, then pulled out and entered his younger sister, alternating back and forth. Liu Min and her daughter faced each other, foreheads touching, breaths tangled. When Xiaoliang finally came inside Xiaohui, Liu Min reached down, spread the overflowing semen around, and then sent it into her own mouth.

This secretive thrill, always on the verge of being discovered, became an addiction for several of them.

One night in mid-August, my husband went on another business trip.

Lü Lin called all four of them into the master bedroom through the intercom. She was especially主动 today; first she had Xiao Liang lie on the bed, then straddled him herself and slowly took him in deep. Then she called Liu Min over and had her sit on Xiao Liang’s face to be licked. Xiao Hui knelt to one side, kissing Lü Lin, while her hands kneaded each other’s breasts.

Only a dim wall lamp was on in the room. Bodies intertwined, the sounds of splashing water and suppressed moans rose and fell. Xiao Liang's tongue skillfully worked on his mother's already somewhat loose yet exceptionally sensitive opening, while his lower body was enveloped by Lü Lin's hot and tight inner walls. He let out a low, comfortable groan, his hands gripping Liu Min and Lü Lin's buttocks respectively, pressing down forcefully.

Who knows how long had passed. Lü Lin went first, her body convulsing violently and pinching Xiao Liang painfully. She collapsed weakly, and Xiao Hui took her place. Xiao Hui was no longer as tense as at the beginning; she could adjust the angle herself, making that thick, long thing grind over the most comfortable spot every time. Liu Min then turned around, lowered her head, and kissed her son, feeding all the liquid that had just been licked out into his mouth.

That night, they hardly stopped.

Xiao Liang ejaculated four times in total, cumming inside three different women. Semen overflowed from different bodies, messing up the bedsheet. Finally, several people collapsed together, sweat-dampened skin sticking to each other, no one speaking.

The air was filled with the sweet, fishy smell after passion.

Liu Min breathed lightly, reached out and touched her son’s firm lower abdomen, then touched her own slightly bulging lower abdomen—inside it was still holding what had just been shot into her. She suddenly let out a very soft laugh, her voice hoarse:

“At this rate... something bad is going to happen.”

Lü Lin turned her head, her gaze still somewhat hazy: “What happened?”

“What if I get pregnant?”

The room fell silent for a few seconds.

Xiao Liang suddenly spoke up, his voice carrying post-coital laziness and an undeniable tone: 'If you get pregnant, just have it. Anyway, this family is already in such chaos.'

Xiaohui didn't say anything, just buried her face in her brother's chest, as if acquiescing.

Lü Lin looked at the ceiling and only after a long while said slowly: “I haven’t taken any contraceptive measures for a long time... What about you?”

Liu Min remained silent. Xiao Hui also remained silent.

The answer is self-evident.

The cicada chirps outside the window had unknowingly weakened, the summer night deep.

The four people in the room were intertwined, none getting up to clean up. Semen slowly seeped from where they were joined, drawing lewd traces on their inner thighs. They all knew that once certain lines were crossed, there was no going back.

And they seem to have no intention of turning back.

The next morning, when sunlight shone through the gaps in the curtains, Xiaoliang woke up between Lü Lin and his mother's bodies. Xiaohui's hand was still resting on his waist. His lower body hardened again, and naturally, someone reached out to hold it, naturally, someone parted their legs, letting him enter from the side.

No one spoke.

Only the faint sound of water and the gradually quickening breath could be distinctly heard in the morning stillness.

A new day begins again, in the most forbidden way.

And this summer was clearly going to be a long one.
