Her nipple was stiff in my mouth. I ran my tongue in circles around it as she moaned loudly.She pushed me away. "I know I have a busy schedule, and ...I know you have a family. But, I will not have a one night stand. I am too old for that!"I pulled her back, to me. "Don't worry beautiful. It may be difficult to match our schedules but we will make it work!" For how long?" she asked as she shimmied out of her panties teasingly.Her pussy was freshly shaved clean. Her folds were visibly. She did admit she saw his hard on, but did she do more than just see it? Of course she nor he would ever admit to that. *******************************************************************************************About a week later, we had another bad storm. This time it was around 10 pm. I could see the flashes of lightning brightening up the sky in the horizon, from my bedroom window. The lightning was more vivid, seeing flashes every two seconds. Sure enough, there was a severe thunderstorm. "So much for the tinted windows..." I laughed softly. "Who cares? Not like he knows us." he whispered. "Now, where were we?" He gave his hips a roll, I could feel he was still hard despite having been interrupted. "Mmm, yes.... right here."I smiled down at him and sat up again. His hands drew to my breasts and he began to fondle them, most likely giving the guy a show IF he could still see us. I began to roll my hips again, pushing forward then drawing back again, though this time I quickened. Carly opened her mouth, and licked inside the big glob of cum that had landed on her lips. "OH wow!" she said, "This is a boy’s cum isn’t it." "Yes it is. Did you get a good look at his cock?" asked Tyler, looking over her shoulder. "Uh, huh," said Carly with a big smile on her face. Bright-eyed Tyler inspected her younger sister’s body as it was now at least partially covered with cum, just.
