At a secondhand lingerie buyback shop located somewhere in Tokyo, women facing various personal circumstances come to sell their underwear. It's common to hear customers say they won't buy if the lingerie isn't clean, while others plead for a few thousand yen. Some sellers hesitate, wondering if their current items are good enough—this is the everyday scene. While empathizing with the sellers, staff take instant photos of the lingerie. Models wear bold, neutrally colored lingerie with daring designs, photographed from behind. Some sellers are forced to show the inside of their panties, confused by the request—"the inside?"—but are gently persuaded to open up emotionally. Some pick out a vibrator, awkwardly holding it against their pussy, though they don't seem to feel much at first. When their nipples are stimulated with a bullet vibrator, they gradually begin to respond and eventually climax. Sellers are asked to remove their panties so stains can be checked and the scent evaluated to determine resale value. Convinced that smell matters, one seller agrees to a 5,000 yen offer for her bra and panty set. Others reluctantly accept the buyback, and used items are swiftly added to inventory. The shop also produces original adult videos, convincing some sellers that appearing can be profitable. A cameraman is called in to begin filming, though some sellers shy away, protesting with a nervous "Wait a second." The staff cracks corny jokes while going down on them orally. Lifting their skirts reveals completely shaved, bare pussies. Large clits emerge, and when rubbed, the girls start writhing with pleasure. Their wet pussies make squelching sounds, dripping with arousal—revealing their truly slutty nature. Blouses are removed, and half-naked instant photos are taken for jacket covers. On all fours, their buttocks are spread wide for close-ups of their anus and pussy. Legs forced open, their pussies are licked with cunnilingus, making them climax in cute, moaning voices. From behind, fingers fuck them deeply, making their legs twitch as their sensitive, sloppy wet pussies orgasm noisily. Bodies pulled close, they're made to touch the cock through the man's briefs. "You do blowjobs, right?" he teases, pulling out a rock-hard, bare cock. She gives a slow, sloppy blowjob, making him moan and tremble with pleasure. With a condom on, they begin missionary sex—her tight, hot pussy grinds as she sucks his nipples. Amid the chaos, they swap spit with a deep tongue kiss, then continue face-to-face in a cowgirl position. Her jiggling, sexy ass bounces up and down. Turned onto all fours, the cock thrusts deep from behind, and the slutty girl starts grinding back on her own. Back in missionary, her legs are tied together as her pussy is pounded hard. Her slick, slippery pussy is worked over repeatedly until she reaches her limit—cum shoots across her stomach. "Come back anytime you need money," she's told, and driven by the need for extra cash, some sellers return again and again.
