As the title implied, this is an erotic manga. While characters from the "man on the construction site" series make an appearance, this work has an erotic focus, so it can be enjoyed as a standalone work and knowledge of previous works is unnecessary. The work contains verbal teasing, throatfuck, anal masturbation exhibitionism, spanking, etc. but at its core, this is a lovey dovey sex story about two consensual men who are dating. (Samejima x Satou). <br><br> Characters: * [Satou]: Fierce looking, but surprisingly diligent. He is currently dating Samejima. * [Samejima]: Looks sleepy all the time, but does a good job. He is kind only to Satou. * [Umehara]: At first he regarded Satou as an enemy.
