As long as you're cool with it."I nodded my head and she told me to go down on all fours. She also went down on all fours behind me and pressed her mo...th up to my pussy. Even given what had just happened, I was still really fucking horny and this felt really good."Put your arms on the top of the headrest, to elevate yourself... so it drips out." she instructed. I obliged.I could feel it finally starting to come out. It felt really runny and cool now, nothing like the hot sticky cum that. I encourage her while playing. On sundays i take her to the tennis court. She is very strong and her assets are very big and tight due to her regular exercise. She uses to wear a t-shirt and shorts while in home which exposed her strong thighs. So i started to have a good relationship with my sister. Our family planned for a tour. My father – business men, mother – housewife, me and my sister. We went to shimala since my father is having some good friends there. We checked in into a nice guest. Things didn't change much until the holiday season at Christmas. We were at a small party up the street, and Debbie was wearing a smart two-piece outfit, which had a rather short skirt and the jacket she had worn daringly without a blouse, just over her well-filled bra. I must admit seeing her dressed provocatively like this and dancing with other men got me hard in my pants. Nothing happened other than I took her home later and fucked her brains out; but it was the best sex we have had in. Except I didn't have a massive long dildo, anyway I wasn't so much worried about the length of Daddy's cock but rather it's width there really was no way my boy pussy could accommodate that and I knew I really needed to stretch myself. I had two butt plugs which I had not yet dared use, but knew that they were perfect for this purpose. They were rubber and looked grossly bulbous and at first impossible to get in my pussy. But this Sissy was determined!I started squatting over the smaller butt.
