We break the kiss and I kneel down in front of him. I quickly undo his belt and buttons on his jeans. As I slide them down his hard cock is bursting t... get out. I pull down his briefs revealing it. He steps out of his clothes as I reach up and grab his cock with both hands. I was right it is a good 8 plus inches of fat hard cockmeat. This is much bigger the Jimmy’s average size cock. It’s probably the biggest I have ever had and my pussy gets wetter in anticipation. I kiss the head and am able. Anyway, I was glad I wasn't living in 1813.Once we closed the door, Judy took her coat off and hung it on a hook; then she unzipped my coat. She pushed me against the door and started kissing me. This seemed to be starting better than I had expected for this setting.She said, "Give me a second."She took off her shoes, then her tights. The tights went into her bag, the shoes back on her feet. She explained why, “This floor is too cold for bare feet.”I knew that Judy was thinking this through. Thinking back, I don’t think that B and I have seen Zack naked for well over a year now.When camping, Daddy always confined our nudity to the camping field and the surrounding area which sometimes included the beach, but this last year, just after my nineteenth birthday, we got quite a surprise when we woke up one morning to find 3 little tents across the other side of the field. We got up and, as usual, didn’t put any clothes on, and started getting breakfast ready, but when daddy and Zack got. We laid there with our arms around each other kissing and fondling gently. My cock was so hard I thought it was going to explode and my shorts were drenched with precum. My sister’s panties had a huge wet spot on them from her pussy juices and the precum that was traveling from my shorts to her panties. I kept glancing at the clock on my night table. “It’s been ten minutes. Do you think that is long enough?” I asked my sister.“Yes, that is more than enough time. They aren’t coming back”.I.
