A little rough. Good idea, but a little rough. Too much noise on the audio. Also the business attire to bikini transition doesn't work in an office environment. It would have been better if she went to bra & panties. The classy, Victoria Secret kind. Black lace.
She's got most of the acting she needs, except the negligent tossing of the top was off. Not right. She's more in the genre of the hot blonde dominatrix vs. the hot beach bunny, so that gesture was also not exactly right. The top comes off deliberately and gets tossed away with deliberation and not negligently.
The hair also needs to transition, from severe and business bun to down. That's a big deal for men. The hair has to start off up, and then come down. A few extra seconds and a few more words won't make much difference in terms of length.
The blouse was also wrong. Too "poofy", and no sharp lines in it where there should be. And the buttons take too long. Snaps, one at a time, and fast, would be better. The camera was too high. It makes her seem small, when the opposite effect is desired. Her gaze should be slightly downward to the camera. And no need to point at the "you". It's a pseudo porn movie. There's only one man in her whole universe, so there's no need to point at him.
Also, she needs to take control of her voice more. She's either in charge, or she's not. (I say she is.) There's no soft little girl in this thing at all. And the slap on the ass well I'm 50/50 as far as if I think it should stay. It's a good sound, makes the hot chick seem more real (SLAP!), but again doesn't really fit.
Finally, and most importantly you have to have the URL of the business superimposed as a graphic.
