"I was surprised at that, but Jeff would not tell me what it was. Finally, the night of the 31st arrived. I enjoyed handing out candy to the kids that...came to the door, but I was happy when that was over.I had slipped out of my robe when I heard a knock at the back door. Jeff was here, and I ran to open the door. Jeff walked in, burdened with an inordinately large number of bags. Michelle followed him in, carrying even more. We went into the living room, and Mom came in to see what we had.Jeff. However, this one will be different from most others. As we wanted to raise funds to help out charities, there will be a charity auction...of the girls that is.Twenty of us would be picked at random from a hat-drawing of our names. We will do a cat-walk before everyone, get nude, and then fuck with whomever came up the winner. It was decided that the people could pool their resources into small groups to bid for one of us....all for charity of course.Of the twenty lucky girls, I was picked. I carried on caressing her clit in just the way she told me to and then I knew that I had to have sex with her, “Come on,” she murmured, and, spreading her legs, I eased over her. My cock touched her pussy and she put her hand down and entered it for me, “Go on,” She whispered, “push it into me……. Oh! That’s lovely darling! That’s right, do me, oh, it’s so nice!” She held me tightly, her fingers digging into my back, her legs wrapped round my waist. I was ready to burst and started fucking her. Before she can finish I open my mouth and say " I know I shouldn't have been texting In class and I promise I'll never do it agin if you just hand me my phone and forget about it this once. " she looks at me and continues talking seemingly ignoring all I had just said. " As I was saying before your rude interruption if you stay here and fuck my pussy with your huge cock I might let you have your phone." I stare at her surprised by her words " you want me to fuck you in a classroom?"I said. ".
