I am the boss now I know his little knicker fetish

My colleague at work has a fetish for wearing stockings and knickers, I found this out quite by accident, and now he is teased by me on a daily basis and he loves it. He is in quite a senior position so he really does as he’s told, afraid of any consequences if the girls in the office were to know his little fetish secret. Once a week I put a pair of seamed lace topped stockings in his drawer, a pair of silky knickers and a bra. He has to go the toilets at precisely ten o’clock when we are all having our coffee break, and put these on underneath his suit.  He has to walk passed us to get back to his office and I love seeing the look on his face which is all red and flustered. Then after I have finished my coffee I go into his office with the weekly figures, I get him to tell me how the lingerie feels and   gets really hard and horny. Only he and I know what he is wearing as he puts his socks back on so if his ankles are showing no one can tell.  I make him undo his zip of his trousers and begin to wank his hard cock underneath his desk, I continue to talk through the figures as he wanks furiously. I tell him what a filthy dirty knicker Fetish wanker he is and I hand him a pair of my worn knickers to explode into.  Then about fifteen minutes later I return to his office where he has to call an Adult Phone Chat line and tell a girl exactly what he’s been up to whilst I listen. It’s great knowing that I am the boss for a while!
