Hasumi is back at the office waiting for a colleague that has hit on her before. There is a lot of work to be done and since they are both back from lunch and have all afternoon to work they are eager to get it all done. The problem is her colleague hears a vibrating sound and can not find where it is coming from. It seems that before he as has arrived while he was at lunch she was masturbating and had her small vibrator shoved up her pussy when he surprised her and came into the office. She did not have time to remove it and that is the sound that he has discovered in her pants. He continues to explore and puts his hand on her groin area to feel for this buzzing vibrating sound. He is surprised to learn that his very conservative colleague uses her lunch hour alone in the office to play with her pussy and use sex toys on her hungry Japanese pussy to satisfy herself. He decides that this will not do and continues to explore her body with his hands making her more and more horny. He removes her Japanese office girl uniform and starts caressing her sexy body. She allows him access to under her pantyhose so he can see how she has her sex toy in her pussy. He calls her a pervert for doing this at the office during office hours and then proceeds to use her sex toy to stimulate other parts of her body. He pulls her bra up and goes to work on her tits. Then he slips off her pantyhose and panties to expose her pussy and begins to finger fuck her as she gets wetter and wetter. He then pulls out his cock for her to suck on after he has spent most of the time with her bent over and his finger deep in her pussy. They both then spend the rest of the afternoon fucking in various positions right there on the office tables and chairs.
