In a secondhand underwear buyback shop in Tokyo, women with various personal circumstances come to sell their used lingerie. Today's seller is Yukari, a tall, charming woman with beautiful legs. She says, "I'm thinking of going to Guam with a friend..." as she pulls a bra and panties from her bag. The shop manager sniffs them and says, "I only smell detergent... I can give you 100 yen for these." Shocked, she replies, "Huh?! I need the money transferred today or my trip gets canceled!" Still, she negotiates. Eventually, a cash purchase is agreed upon in exchange for filming a video proving recent wear. An assistant is called, and filming begins—close-ups of the bra show off her well-shaped breasts. Her mini skirt is lifted for low-angle shots of her panties, clearly showing snug fit and wear. "Since this is my first time, how about 20,000 yen?" she negotiates. The manager suggests, "If you create some wear right here on the spot..." implying she should make stains, which she agrees to. She removes her panties on the sofa and diligently works to leave visible moisture. "Looks like it's pretty stained now..." she says, satisfied. She takes them off from behind, then places both bra and panties into a bag. "You get really wet easily, don't you?" the manager remarks, impressed. Half-naked, she holds the items as a Polaroid is taken, finalizing the purchase. Afterwards, she's invited to appear in an adult video, which she accepts. From behind, her breasts are groped, her bare nipples stimulated. "Faaah~" she moans, sensitive and cute, as her hand reaches for his pubic patch, rubbing her clit back and forth. "Ah! I'm gonna come..." she gasps, as he sucks her tits while fingering her, then licks her dripping pussy with eager tongue—her hips buck as she climaxes. "Your expressions are great," the manager says, impressed. He continues fingering deep inside her pussy, triggering an unexpected orgasm with involuntary urination. Such a prim face, yet so lustful. She gives a tongue kiss, then jerks his hard, erect cock while he fingers her. He sucks hard on her erect nipples. "Aaaah... this is bad..." Sitting on the sofa, she starts sucking his cock—slow, slimy, filthy blowjob. On all fours, she performs kneeling oral, so pleasurable it makes him want to penetrate. "Let's just go ahead and fuck." "N-no bareback!" "So it's okay if I use a condom?" the manager asks. He puts on a condom and presses the tip against her pussy from behind. "Aaah!" Her entrance is tight—the ridge of the head slips in, then slides deep with a slick sound. Her pussy feels incredible. He grabs her peachy ass and thrusts hard into her womb. "Ahh! If you do that... aah! I'm cumming!" He pulls her up by the arms, keeping it inside for standing doggy—Yukari shakes her legs uncontrollably, climaxing repeatedly. "You come so easily. Now sit down." As she lowers herself, he slides his thick cock inside, thrusting vigorously from behind. Her nipples stiffen as she orgasms again and again. In cowgirl position, she grinds down with wet, lewd sounds. "Aaaah! So good!" She rides him passionately, both rocking their hips together. "Auuuu..." He sucks her tits while thrusting upward—her body jerks and twitches with pleasure. On her back, he pounds her pussy while rubbing her erect clit. "Haa, uuuuu! I'm cumming!" Her body convulses—Yukari's cute face during orgasm is captivating every time. He pins her legs down and uses creampie press, slamming deep into her uterus. "Aaah! So deep! I'm cumming!" He pulls out and shoots thick cum forcefully onto her beautiful breasts. "Wow, we got some great footage." The manager leaves the room, confident it'll be a bestseller.
