Located in a certain spot in Tokyo, a high-paying secondhand underwear buyback shop attracts women in desperate need of cash who come to sell their worn underwear and uniforms. Behind the promise of high prices lies a hidden special option. Inside the store, staff carefully conduct photo shoots as proof of wear, and also propose filming sex videos. Using persuasive words, the clerk convinces customers that by verifying their underwear and shooting proof videos, they can double the payout. A video crew is called in to begin filming. The customer nervously reveals her name and age. Among them is a woman with soft, voluptuous breasts, wearing a light pink floral-patterned bra. Next, the customer lifts her mini-skirt to verify the underwear, revealing pink panties and a T-back digging into her ass cheeks. Spreading her legs exposes puffy labia spilling out. The customer strips completely nude, then redresses without a bra. Cameras are left unattended in the store, secretly recording her live changing. The clerk sniffs the panties, prompting the customer to stop him with a disgusted look. Right there, he pulls out a vibrator and pressures her into using it. She puts her panties back on, presses the vibrator between her legs, and gradually begins moaning. The clerk pulls her panties aside to check how wet she is, then presses the vibrator directly against her clit. Gripping her skirt tightly, she moans louder. She ends up leaking a large amount of urine, soaking her panties completely. The clerk says, "Wow, big sister, you're amazing," and buys her items at double the price. He convinces her that she can earn even more by cooperating as a video model. He presses the vibrator against her bare tits, tormenting her exposed nipples. Her nipples become rock hard, then he latches onto her pussy, licking her clit wildly. He makes her stick out her ass, fingers her twitching slit, and causes her big ass to spasm violently as she cums with squirting force. The sofa is soaked with piss. He makes her jerk off his huge cock, then forces it into her mouth. Her throat gurgles noisily as she gags. Her body convulses, vomiting reflexively while drool drips down. The clerk says, "Let's kiss," but she refuses, saying, "Not that—anything but that." He asks if he can penetrate her, puts on a condom, then thrusts his giant cock into her from behind. Gripping her skirt like reins, he pounds her savagely. She screams, "No, I'm cumming!" The clerk says, "Big sister, you want it deeper, right?" as he rams her uterus standing up, making her climax repeatedly. Sitting on the sofa, he takes her from behind in reverse cowgirl, then spreads her legs wide in a reverse M-shape, fully exposing her shaved pussy as he grinds his hips. She takes him completely to the root, eyes blank, convulsing in orgasm. The clerk violently pounds her pussy from below right after she cums. She screams, "No no no, I'm cumming again!" The clerk says, "Big sister, you're soaking wet!" and proposes buying her panties. She rides him in cowgirl, grinding her hips wildly to hit the good spots. After she cums, he pounds her pussy from below, then sprays massive amounts of cum all over her breasts. She collapses, utterly spent, squirting repeatedly. Today's fresh stock of wet panties is now on sale together with the video. Since there's an expiration date, please purchase quickly.
