An ambitious project traveling to 137 universities across Tokyo using a mobile tent. In a late-night talk show style focusing on "sexual concerns," the crew approaches today's female college students and records real sex encounters. This time, they visit O University, known for cultivating globally-minded talent. The surrounding area is famous for fashion-conscious, high-spirited college girls, and among them, they search for students with personal struggles. Though summer break means fewer students around, they approach Hikaru. She broke up with her boyfriend two months ago and has been living alone, maintaining a few casual sex partners. Despite her experience, she comes across as surprisingly honest and open. Inside the tent, a mini-game leads to a forfeit: wearing a school swimsuit. Once changed, her soft H-cup breasts are accentuated, and when touched, she offers no resistance. Sliding a hand downward, rubbing her clit over the swimsuit, she begins moaning with pleasure. Bringing in a male performer to intensify the stimulation, her body quivers with excitement. They admire her firm, shapely ass while enjoying grinding, but she seems unsatisfied. Tentatively, the man offers his cock; blushing, she slowly takes it into her mouth and starts licking. After careful foreplay leaves her dripping wet, he enters her tight pussy. She spreads her legs wide, rocking her body intensely as loud splashing echoes through the tent. Hikaru climaxes repeatedly—her expression embodying pure sexual ecstasy.
