Her breathing deepens and her voice is hoarse as she implores me to bring her to an orgasm. The twin stimulation of nipple teasing and sucking, and pu...sy fingering soon has her exploding into a massive cum. I can feel her juices streaming down my fingers and hand as her cum continues unabated.I quickly kneel between her thighs and replace my fingers with my tongue and lips whilst her first orgasm continues - I'm taking a big chance here - tongue-fucking a pussy is not allowed in these sessions.

I'll see you tonight."I hung up the phone before she could say any more and considered my next move. It occurred to me that I should gather some hard proof about Michelle's affair. It could be a real help in any divorce action. To that end, I purchased a tape recorder that could be sound activated, while I was on my lunch break.When I got back to my office, I decided to stash it rather than answer questions about it when anyone came into my office. I went to put it in a supply closet not far.
