By now his finger was knuckle deep in my ass and he began to slide it back out again.“That’s what is going to make it so good”, he said.Soon his... finger was joined by a second and I could feel a little pain from the stretching of my asshole. On one of his downstrokes, I grunted, but pushed back against his fingers.“Sounds like you’re ready”, he said.He repositioned himself between my legs, pulled my ass towards him, and slid his cock back into my pussy.For a moment I felt relieved that maybe he. . just great fun. Then there is down and dirty sex. That last one is when lust and passion take over your brain in the heat of the moment and you end up doing things that are so blistering hot that you masturbate over them again and again and again. That's what happened yesterday.Jodi got home from work around 4:45. She was more horny than she's been in weeks. That's not to say that we haven't screwed hard and long during those weeks.. but yesterday she was on afterburners. I heard the. " Sandy said. After wiping her eyes she continued "I guess there won't be room in your bed for me if Cassie is there." Oh yes there is!" I replied. "The bed is one of those 'super king' sized beds and there's lots of room for three - maybe even four people. I planned that you'd be in it with Cassie and me."Sandy looked like she would cry again, but came over and gave me another big hug and a long lingering kiss."Mom! Uncle! What are you two up to?" Cassie asked smiling."Oh Uncle Harry was. As he undoes a button he leans over to gently kiss and lick the skin revealed. When he reaches the last button and pulls my blouse open and off over my shoulders, I raise up slightly so he can slip it off. As I do that I can feel his hand reach for the hooks on my bra to open it, so I arch up a little more to make that easier.　He releases the last hook and frees the ends, and I lie back down. He pulls down one strap, then the other and slides the bra off completely; then moves his head down to.
