This project is about going on a hot spring trip with a busty and naughty girl. This time, it's Mika-kun, who has an out-of-the-ordinary bust of over 100cm. She becomes open-minded and touches my dick in the car. As soon as we arrive at the inn, we have sex in the open-air bath in our room. Nighttime play. A mixed-bathing hot spring sex travel documentary with a busty girl, full of travel emotions.
