A boob pub in a certain entertainment district. Saiko, who ended up working at the pub for some reason, was given a training session by the manager. It was her first experience working in the sex industry... Saiko was hesitant to straddle a stranger and have her breasts massaged as he pleased, but once he touched her, her body felt it despite Kokoro. Seeing Saiko's reaction, the manager further teaches her a special raw creampie service. And then it was time for the real thing... The pub was full to capacity right after it opened, with people expecting Saiko to appear.
