Mom was wearing a regular length black skirt, black shoes, and a modest shirt. A regular amount of cleavage was showing, but it was enough to stare at... Mom massaged my balls with one hand; while holding the base of my soft dick with the other hand. She peeled my foreskin back, and without hesitation licked circles around my head. As she did this and my cock swelled; I noticed for the first time that mommy had her hair up in a pony tail. "mmmm... mmm...mmmm," I heard these noises coming from mom. Both girls got up and Becky dived into the tent and pulled the roll mat in behind her, once she had the tent organised she came out zipped up and handed a purse to her sister. They both looked at us as though we had rescued them from disaster, hero worship in their eyes. When we returned to the gazebo additional chairs had already been placed for the twins, Becky next to me then Andrea then Abby, I also noted that big sis had moved a couple of places to be next to Darren, they were cuddling. At the end of her email she said that I didn’t tell her much about myself either and what did I like? Then she got real daring and asked me about my cock. How big was it? How thick was it? Did I have hairy balls?In my return email I gave her my phone number and told her to call me; mentioning nothing else. An hour went by and I gave up on receiving a phone call from Debbie. I thought that maybe she decided to forget everything seems I was impotent. Well soon after the phone rang; I. I walked over and asked her what she has come for and she replied she had come to join in the office. It was her first day. She is in my team where the Hr has given intro about the girl to me later. I was more than happy and started planning how to take her to bed soon and have sex with her and the call centre did not have its own cab service so I had pick her and drop her every day as it was night shifts. This is how I got closer to her in a couple of days and we exchanged numbers and so after.
