One of these days I wanted to have a proper threesome with her and Dave and me, just sweating in our own juices and collapsed on my bed. I felt differ...nt parts of me get wet. My mouth was salivating as my pussy. I know I started getting the flush again. I took another drink of my rum and coke. The taste reverberated through me and send a little heat rush through my bloodstream. It tasted soo damn good, along with David's cum. Both sweet and salty, tastes that complement each other very nicely. Marcella needed no encouragement and pushed herself more and more on the other girl. By this time the besotted Doris loved nothing more than to hungrily fondle, kiss and suck those firm globes and hard nipples. It was almost, although she hated herself for thinking it, a pleasure to have Marlene out of the way so often!For the wretched Marlene was being punished again, although she was still not being sent back to the hold, and the pair were alone for the day. Yesterday, they had been employed. They were big and perfect. She smiled and said, "Ready to go." I nodded and followed her.The trek wasn't that bad. I walked behind Stacey the entire time and couldn't take my eyes off her ass. We reached the viewpoint and we sat on a small bench that had been made. She pointed out stars and planets to me and I tried to concentrate but I was very distracted by her. I think she noticed that too. Eventually, she gave up trying to talk astronomy and instead asked about me. She asked where I came. Her scream was part pain part pleasure (mostly pleasure). It took her a few moments to gather herself but she lifted herself up and slammed back onto my thighs. My cock penetrating her ass deeply. I looked over and say that my dirty little sister was having her ass licked out by Nikki, and they loved it. Again Stacy came crashing down onto my cock, this time I could feel a little juice squirt from her pussy. This was my que. I picked her up, still with my cock deep within her, and positioned.
