With nothing else better to do, the protagonist spends every day alternating between home and work like a machine. One day while heading home after doing overtime, he noticed a post on a social network site looking for a place to stay for the night. Even though he thought it thought it was obviously shady, he longed to experience just a little bit of thrill in his life void of stimulation. He made contact with the person that wrote the post and headed to the meeting spot with both nervousness and anticipation. To his surprise, two girls who looked like high school students were waiting there. After confirming that they were the author of the post, he was about to lead them immediately to his place when they offered to give him a pre-payment first. They headed to a nearby park and he had sex with these two girls who he had just met. Afterwards, he brought them to his house and they fell asleep right away. When he woke up the next morning, they paid him for the night and left while saying that they’ll see him again. Even though he was confused at how casual their meeting and departure had been, he wondered if he just happened to be lucky and thought it might not be such a bad experience. This was the beginning of a strange relationship with the two girls. [From Hau~ Omochikaeri!]
