She asked me what she should wear and I said definitely she should wear black stockings with high heels and no panties, then she could put on a Sharon... Stone act for me. I asked her if she could just wear an overcoat and nothing else apart from the nylons and she said fine.This was all arranged and I went down to the bus stop at the right time to wait.The only problem was that I didn't know what she looked like really and I got a few strange looks from women who walked past as I checked them out. Only a couple of moments later and Pam had Sam's cock out and she was giving him head, too. Then, as the guys enjoyed having their dicks sucked and jacked up and down, Lauren stood and she was soon out of her clothes and then she returned to Phil, took his cock in her hand again and then she moved over onto his lap, using her hand to guide the swollen thick head of his cock straight up into her waiting pussy. Lauren's hot cunt was streaming pussy juices as she settled downward onto Phil's large. I went down again, darted my tongue and started fucking her with that. All I could here was, Stan pls stop, you are killing me. I finally did, I was in no mood to drink her juices so I stopped before she could cum.Well,,,its now my turn to make you happy baby,,,and I was in heaven next moment,,,her juicy lips were around my shaft, heaven was not the word. She finally stopped and asked me to lie down properly. She came on me, holding my cock; she guided it in her hole. It just slid inside. “Well now that I really think about it, you two have done everything together, and it seemed almost inevitable that this would happen” she said. “So you’re not mad at us?” I asked a little surprised. “I’m a little ticked off that I had to find out this way, but I can’t be mad that you committed incest, after all, your aunt and I had our little experiments” she said giggling. I couldn’t believe it, mom and Aunt Lisa messing around with each other? Never in a million years would I have guessed.
