Taking advantage of her college break, she headed to a hot spring town! The most beautiful girl on campus, known for her I-cup breasts that often become the subject of rumors among students. Last Christmas, they agreed to hang out together as single friends, had a toast, and ended up having sex. Though they never officially confessed, they've been in a relationship-like situation. When he asked, "Wanna go to an onsen?" she immediately said yes. For girls, the word "hot spring" is irresistible, and they indulged in passionate love scenes without caring about others. They enjoyed her breasts in the outdoor bath, and though they refrained from sex in the mixed-gender pouring bath, once they returned to the hotel after eating the local soba, he couldn't resist—her massive tits were exposed, and he rubbed his cheeks against them, sucking them wildly. Just saying they'd stay overnight had already soaked her pussy in arousal. Cute, stunningly proportioned, and blessed with explosive breasts, she usually tries to hide her excitement around men, but that day, her female instincts awakened! She repeatedly thrust her pussy deep against him, screaming, "I'm cumming, cumming, cumming!" as she experienced female ejaculation. Her face shifted from tears to pure joy—absolutely adorable. With these breasts pressing against him, he could recover instantly and come over and over. When he creampie'd her bareback, they climaxed together, her convulsing body trembling in ecstasy—an incredibly moving sight!
