So about 8 or 9 years ago i posted a personal ad on craigslist, offering a striptease and a sexual favour to any guy who was interested. Ad had a pic taken in a mirror showing off my girly cheeks. Got plenty of replies and that, but two separate guys enquired as to whether "she" will be watching us or joining in on the fun...after laughing to myself, i explained they are my pics, and "she" will be sucking your cock. Anyway, one of the guys lived quite near, about 5km. He was 58 and married. When he called, i answered the door wearing just a towel, he came in and shook hands....said, "i can't wait to meet her" i says, sorry, i thought i explained, they were my pics! had just started leading the way, walking up the stairs. He followed close behind, and with some force, pulled the towel completely off me...."ohh i understand now" slaps my ass quite hard, his cock is out before we even reach the bedroom, haha. Anyway, that was a filthy encounter, had me posing for pics and all...felt so wrong too, that's what makes it horny.
