At the end of the day you have to weigh up the risks over the reward. Obviously banging a hot prossie in a office/work setting is a turn on but what if she is a nutter and accuses you of all sorts?
PROS: Great fucking session without the costs of buying a hotel.
CONS: Could be caught on CCTV, Girl could be a nutter and blackmail you, you could lose your job, could accuse you of rape, you could damage something in the room, lose your sense of annonomity: she and her pimps now know where you work.
When you weigh up these options you realise it is not worth the risk.
Surely there are other options than your own place/work place and paying for a hotel to get the same high.
