A young man approaches a beautiful high school girl named Mami on her way home from school. He invites her onto his special car where they can talk more privately. She reveals that she enjoys having sex with her boyfriend while wearing a yukata (a light summer kimono). Her eyes are captivating, and her body looks flexible enough for some fun. She has had seven sexual partners so far, and both men commented on how much they enjoyed her big round ass. One even said he likes feeling her wetness down there. The man proposes an exciting challenge - if he finds someone who can make this virgin cum, he will win a prize of 100 million yen! If he can get her really turned on and make her squirt multiple times, the prize will increase even further. They start by bringing in an older gentleman who admits to being a virgin. With gentle touches, he begins giving him a handjob. "Do you like it when girls touch you?" he asks as he teases his sensitive skin. The man responds positively, indicating which areas feel best. As Mami masturbates, she becomes increasingly aroused and begs for more attention. Eventually, she climaxes in an intense M-shaped orgasm. Next, she surprises everyone by offering herself up for anal sex despite being a virgin. She straddles the older man and shows off her tight hole before impaling herself on his massive cock. As they engage in passionate intercourse, she moans loudly about how good it feels to be filled up. Finally, after reaching another powerful climax, she rides him until he cums inside her. Afterward, they discuss whether this act would qualify for the bonus prize money. Despite their initial hesitation due to ethical concerns, they decide that since no one was hurt or forced against their will, it should count towards earning extra rewards. In the end, everyone seems satisfied with the outcome – especially Mami's newfound confidence thanks to her experience with the older gentleman.
