We stopped talking and got into a 69 position for about 20min. I then got her on her back and with her legs spread wide open I went down on her pussy ...nd was licking her sweet vagina. I managed to make her cum a few times each time swallowing her juicy cum. I got her so horny she begged me to bury my 9" cock in her cum soaked pussy. I complied and slowly slid my cock into her one inch at a time. I teased her at first, and then buried my cock deep into her. After awhile inside my sister I knew. Walking into my twin sisters’ ex room, Kalista was doing much the same thing. I asked if I could help, but all I got from her was, “That’s all right Charles, I can do it myself.”I did take the laundry stuff to the its wash Palace, took bags of my father’s stuff downstairs. I liked his taste in ties, so I carefully took some of them up to my room.I came back down and decided to try my hand at fixing something to eat for everybody. I found some frozen pizzas so, I read the instructions, heated up. I agreed and handed Kathy some money. She walked up to the stage and leaned forward to reach the jar. I was looking at the band and the drummer was watching Kathy. He caught the eye of the guitar player and they both looked down at Kathy. She was leaning forward putting the money in the jar and they both looked at one another smiling. I knew they both got a great look down her dress to see her tits and maybe even far enough to see that she didn’t have panties on.Kathy came back to the. In the sudden excitement, I noticed that she had put up a scarlet red lipstick.I became so horny that I kissed her swollen lips.She pushed back and said what are you doing?I said, ma’am, I am sorry but I find you very sexy and I would like to kiss you.She said are you insane.I went nearer her and sucked her lips like a baby sucks a nipple.She began to push me hard and became successful.For a moment there was so much silence that I had no idea what to do.Then I looked at her from top to bottom.
