I was not sure when to expect the first caller but two of the Cambridge girls must have got up very early because it was only a quarter to nine when t...ey called to say they were approaching. Arrangements in the house were simple. I had taken possession of the master bedroom upstairs and when each girl arrived Wendy or Fran would greet her and if I was available she would be shown upstairs without any more ado. If I was engaged, she would be given a glass of wine and invited to wait in the. Slowly she knelt upright, my cock flopping from her mouth, still hard but no longer full of cum."Mmmmm," I heard her say, her mouth full of my cum, and without prompting she swallowed it, taking my cum into her belly. "Lovely," she whispered and bent and licked some of the dribbles of cum that had coated my cock."Do you like the taste of my cum?" I asked her."I love it Mr Matthews, I never knew how tasty it was," she answered, and I noticed that her hand was down between her legs and had dipped. They seemed like a reasonably normal couple, other than their own age difference. To refresh your memory, Amy was twenty-five, and Bob was forty-two. Talking to Bob and Amy would be a little tricky. We'd have to find a way to broach the subject without the presence of others. Especially since no one knew about Rebecca's and my involvement in such things.During one of these nights, Rebecca and I were inside our daughter's home, tending to the last-minute needs of our grandchildren. They were. “That feels really nice,” she smiled up at me.“Yes it does, I might have to get it out soon.”“Well I would hope so,” Maria laughed.“Won’t your husband and son mind?”“Not at all, I’m sure their cocks will be coming out soon.”I looked around the room and saw that Anthony was becoming far more tactile with Hollie, stroking her bare arms and her hair, while Clarissa had Matt’s strong arms wrapped around her.The whole situation was turning me on, and I wondered how the evening would progress.
