There are beautiful girls who sell used underwear on a popular flea market app to earn extra cash, and rumors say that through private messages on the app, various additional options can be negotiated. Today, we bring you the hidden behind-the-scenes footage of these secret options. One of them is Senna, who sells her panties while insisting with a pure, innocent face, "I'm totally not perverted at all~." That pristine expression is so gorgeous, it only makes me more frustrated. We move to another location to begin the live stripping shoot and inspect the goods. Checking the condition of her panties in a quiet, deserted mixed-use building, the result is just as expected. Cool-type beauties usually keep their panties clean for sale. Well, can't blame them. But even when I dangle the condition—"I can't buy them unless they're properly dirty"—Senna still keeps her smug attitude, saying, "I did wear them, so it's not my fault they're clean..." Her defiance only fuels my determination to break her. At this point, the real thrill lies in pushing things all the way. I corner Senna on a stair landing and hit her with intense vibrator stimulation. "Ah! Nnn...!" Her innocent facade slowly crumbles, and flashes of her lustful true nature begin to surface. Seizing the moment, I slide my cock into her cute mouth, sending my excitement soaring to the peak. Senna moans a little too loudly—did we get caught? But there's no awkward breakup here. Instead, she whispers, "It's safe, so..." and we head straight to a love hotel. As I relentlessly tease her with the vibrator, she surprises me with how naturally she gets wet, taking charge of her own arousal. The prim and proper lady from earlier is long gone—now she's moaning the loudest around my fingers. I press her soaked panties against her dripping pussy to "inspect the quality," keep the live stripping cam rolling, and move straight into the gonzo sex option. She protests, "Eh, seriously, no way!!" "Put on a condom then~!" but she's clearly into it. Proof? The moment I thrust deep inside her, she lets out a cry of pure ecstasy that echoes through the love hotel: "Ah! Aaahn!"
