On duty, but... she's inserting herself into you! Lucky skating with a female boss in a warehouse!

"That hit me in a sensitive area...uh...don't move...no...no..."
As punishment for being late for work, the main character, Yahata, is ordered by his boss, Chief Shiraki, to help her work in the old warehouse.
Yahata is optimistically happy to be alone with Mrs. Shiraki, but during the work, one of the buttons on Shiraki's blouse pops off, exposing her big white tits wrapped in her bra!
Just then, Masuoka, Shiraki's boss who is a sexual harasser and a big pain in Shiraki's ass, comes to the warehouse with his subordinates in tow.
"What do you think is going to happen when he sees you like this?"
Yahata hides between the shelves and cardboard boxes as Shiraki pulls him along, but his crotch reacts to the close contact with Shiraki in the cramped space...
Shiraki notices this and begins to wriggle in embarrassment, although her mouth is angry.... Yahata has unexpectedly had lucky escapes in the warehouse, in the elevator, and with his beautiful boss whom he admires and his colleague OL who is an idol of the company!
The girls, who had been holding back so that their surroundings would not be exposed by the sudden situation, gradually begin to breathe hard and get excited, even though they are ashamed...
