A 20-year-old office lady in uniform working at a railway company is approached after work, looking visibly tired. The next day, during a break from her job, she's successfully invited into the Magic Mirror Van. She's told the rules: "Sustainably get an ED softie hard through grinding and make him cum—win 300,000 yen!" Hesitant at first, she hugs the ED man and begins grinding against him in black stockings. Smooth dry humping continues, along with sadistic nipple play and footjobs, gradually making him harder. "You're getting hard," she murmurs. "Yeah... I do like it when it's hard... (blushing)." She leans forward, hands on the ground, showing off her black-stockinged crotch—squelching, slightly wet. "I'm getting wet," she admits, slathering lube onto his bare cock. Ayumi's touch turns filthy, a growing damp spot on her panties. "I leaked◆," "It feels so good◆," "Ah, ahh~nn, I'm cumming!" She gushes with slippery grinding, squirting hard. After fingering, she gasps, "Maybe I was really pent-up," "Ah, I'm gonna cum!" Now confident, he takes over with a rock-hard giant cock. "Wait, wait!" "I have a boyfriend!" "Bareback will mess with my work!" she protests, but soon she's riding him cowgirl-style, teasing his cock—then hit with a thick, pulsing creampie, successfully claiming the prize. "Please keep helping me stay hard and build my confidence!" she pleads as her big tits are groped and her nipples sucked—becoming hypersensitive, on the verge of nipple orgasm. Vibrator play makes her perfect ass twitch. "Can I make you feel good?" she asks with a coy, upward gaze before giving a lewd blowjob. Her waist is slim, her tits huge—her body arches like a shrimp with every thrust. "Hit deep inside!" "I'm gonna cum again!" "Aaah—no, no, nooo!"—splattered on her face, in her mouth. He erupts a massive load, which she licks clean with eager tongue, his cock still rock hard. "You came in my mouth◆," "Your cock's even more seductive than my boyfriend's◆"
