DeepL Trans:
Ryoichi Torii jumped on the bandwagon and became a food and beverage delivery man. He thought it would be an easy job where he could earn money just by driving around town freely. However, the harshness of the situation was beyond his imagination, and he became desperate.
One day, he is seduced by Hitomi Serizawa, a married woman who has a surplus of sexual desire at her workplace, and they engage in sexual intercourse. Hitomi says that there are plenty of married women like her, and she can introduce him to a few of them.
His well-trained body can be used as a commodity! Ryoichi realizes this. He opens an underground website called "Robotsu," which offers a business trip bed-catching service.
The site is steadily gaining popularity, and among the requests he receives are those for his wife to be taken as a cuckold. Among the requests, some were for him to bed his own wife, others for him to humiliate others, and so on. ...... However, Ryoichi, who has had his fill, no longer has a choice but to turn back.
