It only happened every now and then, but when it did it was worth every guilty hidden penny. And tonight was one of those nights.She was 27. Living in...Fulham, in SW London and had already cum once on the other end of the phone. Arthur was only average looking but his way with words was as strong as his drive to make strangers cum in the middle of the night!In only 20 minutes of traded messages, he'd already learnt that Sheena was an accountant. Her boyfriend was away in the states on business.. The scenario was great. I was riding this cock, had someone watching as I was doing it, naked outside in the backyard in the hot tub. I couldnt tell you how hard my heart was pounding. The pounding I was giving to my ass was epic. I was changing positions and really putting on a show. It was time to be "caught." I turned to change positions and saw that she was sitting there watching. I still had the dildo in my ass and was riding it as I noticed her. What I didnt know is that she was really. .. uhhh .... mouth and you must not take it out whilst I'm ... he's ejaculating" I corrected myself. "Do you ... uhhh ... understand?"Sam nodded, keeping the pace, her body tensing slightly in anticipation of what was to come.I went on: "If you want to be a really naughty girl; if you want it to be fantastic, you'll swallow it for him. Is this something you want to try?"There was a slight hesitation. I sensed at this point she might not have expected me to ask her that. She nodded again, eager. Janis was first naked after he left and Clair wasn't far behind. Janis asked if I was up to doing some more on her butterfly. I said sure enough, just give me a few minutes to get set up. I went into the tattoo studio, turned on the music and started getting the gear together. The girls came in and placed a towel on the chair before Janis got in position.When Janice was ready I started to get into position and I looked over my work and it had not healed enough to continue yet. I told them it.
