I can still somehow remember the plot and some of the scenes such as:

-they are office workers
-the subordinate likes virgins
-the superior is a virgin
-they decided to have sex
-the superior(bottom) got hooked in having sex
-they had sex in the archive room in the office
-the seme came, in order to prevent it from leaking, he covers the uke's ass with tape
-the uke, during a meeting came/peed himself

thank you, I was searching for it because I am planning to recommend it to a friend...
