The Older Sister Who Gives In

On an evening when their mother is away, a younger brother asks his older sister to bathe with him. She initially refuses but eventually washes him in the bathroom and joins him in the tub. After kissing and fondling, they fetch a mat from the changing room, spread it on the bathroom floor, and have unprotected sex. They check outside for their parents' return, and the brother asks to sleep in her room. After bareback bathroom sex while their parents are away, the younger brother later visits his older sister’s room at 10 p.m., receives a paizuri while she looks at her phone, and cums on her breasts. They then kiss and caress before having bareback vaginal sex on the bed, ending with him cumming inside her. While their parents are out, a younger brother coaxes his older sister into bathing together as they did before. She wants a slow solo bath, but after he admits he has no condoms left she tells him to cum outside and ends up joining him. They wash each other in the shower, enter the tub, kiss and fondle, then fetch a mat and condom from the changing room and have sex on the bathroom floor beside the tub. Positions include her on top and him lifting her against the wall; when he asks if he can cum inside she only tells him to keep moving. After finishing they carefully leave in case their mother has returned, and he asks to sleep in her room, which she refuses because she has homework. While their mother is away, the older sister joins her younger brother in the bathroom. They wash each other with intimate contact, kiss and caress in the bathtub, then have sex without a condom. Fearing their mother may return, they move to the changing area and continue intercourse; afterward the brother wants to sleep in his sister's room. After her shower the nude older sister is asked by her younger brother to let him sleep with her. At dinner their parents say they will be out the next day, and the brother texts her asking for paizuri. At 10 p.m. in her room he gropes her while she browses Instagram, receives paizuri, and cums on her breasts. They kiss and caress, then have bareback sex on her bed ending in creampie; he wants to sleep still inside her. Older sister and younger brother have penetrative sex and a creampie in bed while their parents are away, then sleep. In the morning the parents have already left early; the brother gropes his sister at the sink. Learning the parents return tomorrow, they plan to sleep in the living room, where she gives him oral sex, they strip, have cowgirl sex on the sofa, and he creampies her again. Sweaty nude older sister drinks soda then bathes with her younger brother. He washes her back and gropes her breasts while she thighjobs him; they soak, deep-kiss and she gives oral sex before straddling for more kissing. After drying with towels and a hair dryer she changes into a gray tank top and shorts, smothers his face with her bare breasts and handjobs him on the living-room sofa during baseball commentary, then helps move a table, makes the bed and lies beside him on her phone while he asks for kisses. On the bedroom futon the younger brother kisses his older sister and gropes her breasts, then asks for a breast job; she gives a paizuri through and then with her gray tank top pulled up, and he cums on her face and chest. She next puts on a white dress shirt and blue plaid skirt from her room and gives him a footjob in office-lady clothes, opens the shirt, shifts her panties, and he cums heavily on her feet. They resume kissing while he fondles her bare breasts; she straddles him in the open shirt and white panties as he tugs at the fabric. The older sister and younger brother have intense cowgirl and missionary sex with multiple creampies. The next morning they have bare sex and another creampie, then he finishes with paizuri between her dark-blue bra cups. When their mother comes home they pretend they slept in separate rooms, and he texts a joking request for more condoms. The work then presents exterior, floor-plan, and room notes for their 1980s Seoul suburban family house. A house layout (living room, kitchen, bathroom, master bedroom, brother’s room, sister’s room, balcony) is introduced while the older sister rides her younger brother on the living-room sofa and learns their mother will arrive in minutes. After one more round she sleeps on the sofa in grey loungewear. Later, dressed in a black turtleneck and beige skirt to run a store errand, she argues with him about the outfit, sits in his room, and he peeks at matching underwear until he is hard. She gives a handjob and blowjob, lifts her top to bare her large breasts when asked, takes a cumshot in her mouth and swallows, then puts on a coat and boots while they discuss rain and umbrellas. In the rain the younger brother and older sister share one black umbrella. At a supermarket they buy detergent their mother requested; at his urging she randomly drops a 0.01 condom box into the cart. Flashback/home scenes show them having intense condom-protected vaginal sex while fretting that the shaking bed and noise will alert their mother downstairs, then climaxing. After checkout they eat at a restaurant, where he teases her huge breasts and feeds her sausage. Outside in the rain again they discuss where to go, then in a home bathroom—while their mother is in the house—he lifts her shirt, bares her breasts, pulls down her bottoms, and begins penetrating her. While their mother is in the living room, the younger brother stands and penetrates his older sister in the toilet with her T-shirt lifted and bottoms down, then creampies her. They later check into a large motel room with a big TV and karaoke; when she goes to bathe he joins her to wash her. Nude under the shower they hug and he asks for a breast wash, so she gives him a titjob until he ejaculates on her chest and into her mouth. He then lies on the bathroom mat and asks her to climb on as a warm blanket. Older sister and younger brother lie fully nude on a motel bathroom mat for cowgirl, missionary, titjob and cunnilingus, then enter the bathtub for hugs and penetration. After bathing they towel off, talk about hunger and dinner, then resume multi-position sex, creampie and paizuri on the bed and wipe cum. They fondle under the covers with a phone, sleep, and in the morning the brother wakes with an erection beside the sleeping sister. On a motel morning the younger brother slides his erect penis into his sleeping nude older sister’s mouth, fellates her, and ejaculates inside. She bathes again because of the semen, dresses in teal lingerie then a black sweater and green skirt, and they leave holding hands. After a dark-bikini fitting and penetrative sex with cum, at home on tatami under a phone-charging pretext he gets a footjob and under-sweater titjob, cumming on her breasts. When she mentions a Gangwon-do sunrise trip with friends, he offers to go as her fake boyfriend and starts undressing her. The older sister and younger brother have bareback doggy-style sex fully nude on a room mattress. He promises to pull out but cannot hold back and creampies her. Later under a kotatsu she eats mandarins while giving him a footjob. Next morning in the laundry room, after washing and laundry talk, she gropes him from behind, kisses him, lifts her top for breast play and a handjob, warning that their mother is home. In the living-room kotatsu he crawls under her seat hunting a power plug, nuzzles her for minutes until she is sweaty and topless, then she starts fellatio while he asks to put it in without a condom. In the living room the older sister and younger brother have penetrative sex and creampie, then continue while kissing. After she goes out in a mask and outdoor clothes they have sex again in a public toilet, return to his room for multi-position nude sex and creampie, and agree to keep going until their mother comes home. After full-nude bedroom missionary sex and creampie, the older sister and younger brother rest and decide to drink barley tea. In the shower the brother washes her, gropes her breasts, kisses her, receives a handjob, thrusts between her thighs and buttocks, and penetrates her. After the bath she wears only an oversized grey shirt on the sofa, lifts it to bare her breasts, then in grey lingerie does armpit play and paizuri before resuming full-nude cowgirl sex. A black-bikini pool scene appears; later at home in grey sweats she delays shopping, lets him bare and grope her breasts when he brings clothes, and performs oral sex on his erect penis on the sofa. On the living-room sofa the older sister gives her younger brother a nude paizuri, talks about her wet panties, then continues with missionary and cowgirl vaginal sex until he creampies her. Semen drips out and soils the sofa; she tells him to wipe the smell, dresses, and styles her hair in a grey turtleneck and plaid skirt while preparing to go out.
