It had only been in the past few years (her late teens, early twenties) that she finally put her finger on it.The way they acted around a certain grou... of people at the Pines seemed more intimate than with others. There would be frequent touches and hugs, and intimate teasing banter back and forth. There were the times that her parents would go on long hikes to the falls with another couple from "the group" as Sandy came to think of them. And there were the evenings that they spent with that. I thrust into her again and again and again until she screamed with an orgasm. Her orgasmic yells drove me over the edge and I pumped my load into her, moaning with pleasure. My cum hitting her insides made her orgasm again even before the first one was over. I pulled out of her and sat down on the couch with a thud, feeling unbelievably tired. But then my cock did an amazing trick right before my eyes. It twitched and began slowly rising back to life, probably because Sarah was fingering. As the night progressed our little chats got longer and even some flirting went on. When 10 o’clock rolled around she said she was leaving for the night. When she told me this she reached out and touched my arm, smiled at me, and the look in her eyes was unmistakable. She was looking forward to seeing me the next night. She turned and walked down the hall toward the elevator where the other two women were waiting for her and said “see you tomorrow.” WOW, now I couldn’t wait for the next night.. I swear that caused two distinct, sequential climaxes to wrack her body, causing her to arc, jerk and bend before she crumpled onto my legs. I had to wait for my member to go flaccid before I could separate us. Then I pulled her onto the mattress, put my arms around her, kissed her forehead, and immediately fell into a pleasure-induced slumber. I normally sleep on a king sized bed, but somehow I had enough room along with this celestial being on just a twin mattress. When we woke up the morning.
