"Dad, you ain't gonna believe this shit! You've heard of Dark Matter, right?"I confessed that I had, but didn't know all that much about it. "That's O...", he said, "Not many people do. It's strange how something that makes up most of the universe, is so hard to isolate. We've done it, though."I knew scientists had been wrestling with the concept for decades, and my curiosity rose quickly. I asked him to explain, and he started a slide presentation.Five minutes later, my head was spinning. After. Cal's eyes were glued to the smallish pink shorts that were pulled seductively into the crack of her ass, distorting slightly the embroidered word “JUICY” that swayed delightfully as she walked. She stopped, just inside the door, so that as he entered he could not help but run into her. As he did, his midsection pressed up against her butt and he put his arms on her shoulders to keep from falling. He suspected she could feel his cock, which by this time was straining against the boxer briefs. "I feel fit. No more pain, either." Good." Oh, yeah, and something else seems to be coming back, too." What?" My libido," she giggled. "It's been a while," she said softly."Yes, it certainly has." You've been patient." I've been masturbating. A lot." Sophia giggled at him. "But I know that you've been tired, what with the skating and Betsy waking us up in the middle of the night, so I wasn't going to push it." And I'm grateful, but the doctor said six weeks, and I've shut you off for three. I pulled her down on the floor and assumed the position my Mom and Candy had. It took me a moment to straddle her face before I could lower my head between her legs. I had never seen another girl’s pussy close up and took my time examining the matt of her push and the shape of her labial folds. They were moist and parted easily under my touch to expose her pee hole. My warm breath seemed to cause her petals to thicken and moisture to flow from her pee hole. I placed my tongue against her pee.
