This is the fifth in a series of shocking videos captured by multiple cameras set up on the women's only floor of a business hotel frequented by business travelers. A neat and tidy office lady gropes herself on the 19th hole before a golf outing, an office lady brings her work to the hotel and starts masturbating while typing an e-mail, a sexually frustrated office lady with marshmallow-soft big breasts looking for a boyfriend - we take a peek at the shameless masturbation lives of each of these women in a space where no one can see them!
