A couple passionate about baseball, Dan and Maina, finally embark on a long-awaited away game trip to a new stadium in northern Japan, planning a day return. Though they've booked their flight, the match unexpectedly goes into 12th inning extra time, ending in a walk-off 8-7 victory. Naturally, their flight has already departed, making a timely return impossible. Thoughtful Dan quickly books a hot spring inn. Once settled, they drink sake via room service and become intoxicated. When Dan says, "I'm all sticky, let's use the room bath," Maina asks, "Aren't we going to the outdoor bath?" But Dan replies, "Don't be such a girl," sparking Maina's curiosity—she begins passionately licking his entire body. She pours leftover sake over Dan's body and licks it off, repeatedly flipping him over to torment him with humiliation play, bringing him to intense arousal with her uniquely skilled, oboe-like blowjob. Laughing as she watches Dan pant and moan, she intensifies her assault. Sweating heavily, they continue with vigorous sex in cowgirl, reverse cowgirl, and ball-grabbing cowgirl positions, switching roles repeatedly, with creampie after creampie, ultimately releasing ten loads of cum by checkout time. [Maina] 25 years old, works at an advertising agency. Discovered Yuji Sugiyama on YouTube, which sparked her interest in baseball. Was in the marching band during school and has experience cheering at Koshien preliminaries. Cheerful and action-oriented, she loves sex and can switch between dominant and submissive roles—especially when drunk, she becomes extremely lustful. Her hobbies include tea ceremony, flower arrangement, and calligraphy. Once she sets her mind on something, she'll endure any trial to achieve it. Secretly, she's a married woman. [Dan] 42 years old, single and in his unlucky zodiac year. More obsessed with pro wrestling than baseball. A financially comfortable IT entrepreneur who fell for Maina at first sight through business dealings, establishing a friends-with-benefits relationship. Influenced by Maina, he's become hooked on attending baseball games, using rapid-fire puns to melt women's hearts. Endlessly energetic and deeply passionate about sex.
