You've heard rumors about beautiful girls selling used underwear through a flea market app to earn extra cash. Through private messages on the app, various arrangements become possible. This time, you encounter a rare listing: a financially struggling housewife exuding mature charm. While older women occasionally appear on the site, a refined, elegant married woman like this is extremely rare—meaning you must act quickly to secure the deal before rivals notice. Matsu Yukino is selling her panties for the first time. Her husband's reckless spending has left her short on money this month, forcing her to resort to this. As negotiations progress to help her out, you meet in a quiet parking lot to inspect the panties. Her graceful demeanor instantly arouses you. She teases, "Suck it, I'll upload it," while blushing and whispering, "...But I'm embarrassed..."—only fueling your lust further. You guide her to a love hotel. Surprisingly eager, she allows oral sex, and the private setting creates a mutual sense of purpose. Muttering "I'm so embarrassed..." she boldly thrusts her hips forward, revealing her slightly stained panties. What began in the parking lot resumes naturally, but clearly too shameful for outdoors—inside the hotel, she abandons her shame, giving an intense, sloppy blowjob with loud, wet slurping sounds. Words are few; understanding each other as adults, you silently slide inside her. The moment you enter, she gasps, "Ah, amazing!! So good!!!" Completely lost in passion, she releases all her pent-up frustration. Fully satisfied, having earned money and fulfilled desire, she returns home to her waiting husband.
