In a special storyline, Yuu Shiraishi, the ace of the girls' soccer team, joins the boys' soccer team to train for the national championship. Forced to change in front of the boys, she begins training in just her panties. As they make her do squats to strengthen her weak lower body, her honest reactions excite the boys. The pleasure building deep within her tired body makes her look up at the boys' faces from below, creating a sensation like scoring a goal. To allow freer movement, they remove her panties, then use a vibrator and electric massager to loosen her tense muscles—Yuu cries out, "I can't take it anymore!" Her responses only fuel the boys' growing interest. During upper-body training, she experiences double blowjob while being stimulated with a vibrator. The boys perform four-handed fingering, framed as "defense training," followed by scenes of her bent over a ball with two fingers inserted, making her squirt repeatedly. In the second half, she takes deep thrusts in cowgirl position, then they toss away the condom and creampie her bareback. Can she endure the relentless cock attacking her in various positions? Enjoy the passionate, hardcore journey of Yuu as she fights for national victory.
