"That was so good. It was thinking about those women that made me cum so much and so quick."Mom looked up and me and smiled a cum filled smile, and th...en started to lick my dick clean, paying particular attention to the tip by sucking any cum left in and around it. She even scooped up some of my cum which had fallen on her robe with two fingers sand placed them in her mouth. Fuck! After a moment she said, "I love your thick, creamy spunk you dirty boy. I know you like the thought of those dirty. Because for the past two days you only fuck my mother. You leave me alone in that way.I laughed so hard I almost lost my breath. She was not amused.Abbey, you could barely walk this morning!

I just had to smile in return. “Hi sis!”. Caitlin pushed the covers down toward the foot of the bed so I could crawl over her to lie between them. I noticed that they had spread a towel over the sheet and were lying on it. Before I joined them, I took the box of condoms out of the night table drawer where I had put them in the morning and emptied a few onto the table for handy access. Once I was on the bed between them, I kissed them each.Then I turned to Dee Dee to softly ask, "What do you want to do tonight?"She looked at me shyly.
