My thank you gift to both of them for helping me out will be something they both will not expect. Karen lost her job last month and she is having to d...p into her life savings in order to pay for Jacob's college, but they have no idea I have already paid it for them, so this will be a huge shock for both of them. I really want to do this for them. I hear a horn. I look in my drive way and see Karen parking her car. She and Jacob get out of the car and run over to me. “I am so happy to see you. I put on an extra clean sheet so that becky can have a cherry juice trophy to hang up in her bedroom just like Valerie has.”On our way to mom’s room we stopped at Val’s bedroom to obseve the virgin blood stained sheet used as a wall hanging at the head of her now seldom used bed. Mom informed Mitzt and Becky that this was to be their room to use if they had to get a momentary rest away from all the others during their stay.Mom had placed some chairs around her bed. The video camera was already. I took hold of my cock and slid it up and down her slick wetness, Catherine gave a little squeal as I did this. I moved forward on my hands and nudged her little pussy with my cock, the feeling of a hot wet virgin pussy on the end of my cock was intense! The natural instinct to push to seek pleasure took over my mind, body and soul.I pushed my cock slowly into my beautiful sister's pussy.Catherine's eyes widened with the shock of my cock entering her, I was about a quarter the way in and still. Dan stood up and turned around, facing the girls.“UNCLE DAN!!” Diane and Brenda screamed in unison. They rushed over, wrapping their arms around his upper body, practically knocked him over with enthusiasm. Dan could feel Diane’s tits press hard against his left side while Brenda’s filled in his right.“Hi Diane, hi Brenda!” He smiled, putting his arms around both girls at the same time, hugging them close. He exchanged kisses and hugs with them.“My, my, have you both ever turned out to be such.
