Dan and Maina are a baseball-loving couple. They're both busy with work, but when the time is right, they go to the baseball stadium to watch games. Today is their long-awaited trip. They've always wanted to go to a new baseball stadium in the north. But work commitments mean it's just a one-day whirlwind tour. They've even already booked their return flight. ...But the heated battle dragged on into extra innings, with the game ending in a walk-off 8-7. Of course, the time for the flight had long passed... and thoughtful Dan had booked a stay at a hot spring inn. When they arrived at the inn, they were inebriated from the sake that was served in the room. Dan: "Well, I'm drenched in sweat, so I'm going to take a bath in my room." Maina: "Eh? Aren't you going to the open-air bath?" Dan: "No, my body would be sticky..." Maina: "What are you talking like a girl? "You know I like the smell of sweat, right?" He pushes Dan down like a beast, strips him of his clothes, and licks his whole body. He pours the half-drunk sake onto Dan's body and starts licking it. He humiliates him by doing a reverse cowgirl. His unique blowjob is like playing the oboe. It feels really good. Mai can't Kokoro but laugh at Dan's panting. His mischievous side is ignited. They engage in sweaty and intense sex in cowgirl, reverse cowgirl, and reverse cowgirl. In baseball and sex, there is always a switch of roles. This time, Dan restrains Maina standing and tickles her in revenge. At that moment, Maina receives a call on her smartphone... from her husband... Maina answers the phone naked so that her secret affair won't be discovered. Dan finds it amusing and tickles her and makes her squirt with his fingers. Oh, the poor husband on the other end of the phone... He repeatedly switches between offense and defense, such as deep blowjobs in the hot springs and sleepy sex in the early morning, and even cums inside and swallows 10 loads of semen before checking out!
