They were in a playful mood and I knew they were going to fuck. Sneaking out my bedroom window, I quietly went to my parents’ bedroom window. I got ...here just in time to watch Dad undress Mom! God her body was even more magnificent than I had envisioned. As soon as Mom was naked, she started undressing Dad. When his pants hit the floor Mom immediately sunk to her knees and took Dad’s cock into her mouth. Oh my god it was so hot watching Mom suck Dad’s dick. My cock was rock hard and aching for. It was dark in the car, so I couldn't see well, but I'm sure there was some fiddling about between Julie and Dave on the way back to the rooming house where we lived.When I opened the door to my room, Julie and Dave came in behind me. They started kissing and groping each other. Wow, I hadn't expected things to go so fast. They were hot for each other right now; it had been two days since our first and only threesome together.They kissed and groped and hugged each other just a minute, and then. Mike and Tarryn were too already here and soon we had all met up up, exchanging hugs and kisses, greeting each other before deciding on what movie we should watch. As we debated on a movie it was clear that all 4 of us was in a mood for something more fun than just sitting in a cinema. It was Tarryn that made the suggestion of, " shall we skip the movie and have some fun?" "What fun exactly, are you referring too," I asked and as we walked away from the movies she told us her plan of to rather. “What’s a girl to do? You two have been tormenting me all week with your displays, so I need to take matters into my own hands” she said.She gave me the same devious look her sister does when wants sex. Their resemblance was uncanny I struggled some more and told her she was crazy and that I would be late for work. None of this mattered to her. I told her I would tell her sister what she was doing and she laughed at me. “What will you tell her” she asked? “Look at how hard you are right.
