On a certain flea market app, beautiful girls sell used underwear to earn pocket money, sparking buzz about the various options available through message negotiations. Interactions with them start as simple app conversations but gradually escalate into wilder developments. For example, when one says, "I'm so tired from being out all night, wwww, just buy my panties already!!", she loudly shouts it in broad daylight, forcing an immediate detour to a back alley for a panty check. Through these exchanges, her true personality and attitude start to show. Meanwhile, others act surprised with "Huh? I didn't agree to that wwww," even after confirming options via DM—turns out, pushing shy girls doesn't work here. Ugh, these outgoing, trendy female college students are tough opponents. Every chance they get, it's "Hey, add on more!"—money-grabbing girls constantly demanding cash. Just when you finally make it to the love hotel, your wallet's in ruins. All this cash isn't from kindness—it's purely driven by the desire to enjoy her rock-hard, perky G-cup breasts. Now, alone with this girl in a private love hotel, it's time to erase the reputation of being a pushover. But just as you get serious, it's "Extra charge, okay~!"—everything costs money! So you boldly slap down ten more bills, and when she stammers, "Wait, seriously...?" you don't miss a beat—that's your opening! Even when you tease her with toys or aggressively grope her tits, she fires back, "That's included in the flat rate!" launching a counter-offensive, turning the tables as you dominate the cocky girl. "You're seriously a pervert... gross~," she says, yet her pussy keeps getting wetter. So when you forcefully shove your cock into her fair-skinned slit, she whimpers, "I only do this with my boyfriend~," such a cute lie, huh? You thrust deep, hitting spots her boyfriend could never reach, making her climax over and over again!
