24-year-old insurance worker Miku approaches an office lady resting in the park. Her fair skin and big tits, visible even through her uniform, immediately catch attention. She's invited to join a game where she can win 300,000 yen by making an ED man ejaculate. "Do I have to take off my underwear? Just the pantyhose?" she asks, before mounting the man with hospitable enthusiasm. Using her lotion-slick legs, she sensually strokes his limp cock, watching with delight as it gradually hardens. "It's getting harder little by little, isn't it? (giggling)." Her oil-covered legs and ass glisten, and as she gains confidence, she starts grinding her pussy against him with lewd hip movements. "My hips are moving on their own! Ahhh, I'm cumming!" Unexpectedly hit with a powerful orgasm, she panics: "Oh no, I might've peed! Oh no, it won't stop! I'm doing it again!" Faced with his unexpectedly large, hard cock, her expression changes completely. "I want you inside me!" she pleads. Her pantyhose tear as he thrusts deep, immediately switching to rear-mounted cowgirl position. "Your cock, your cock... it's so hard! And it's lasting!" she moans, riding him with filthy, pounding thrusts. Looking back with droopy, lustful eyes, she asks, "How is it? Does my pussy feel good?" Her thick, juicy cunt gets creampie after creampie! Her beautiful legs shine in the slick black stockings. A reward fuck from blowjob to bareback doggy style. Her elegant, composed face twists into a wild, orgasmic grimace. "So intense, so intense! Cum in my mouth!" she begs, sticking out her tongue just in time for a cumshot. Slurp! Perfect ejaculation! "Were you really ED? You stayed rock hard the whole time. It's been a while, but I'm actually turned on now!" She claims her prize money!
