Ms. K, who works in the product planning department, is an intellectual type who wears glasses. However, in reality, she is a dirty office lady who gets off immediately when her vagina is lightly touched! We make a surprise visit to the company as a prank! When we show her my dick in the kitchen, she happily takes it in her mouth! When we secretly have a threesome in the reception room at night, she moans loudly and climaxes many times as she is thrust into with a hard piston!
