She was in complete pleasure as Rob sucked one, then the other nipple in his mouth. She opened her eyes briefly and locked on mine, the pure lust in h...r face as her knees were beginning to buckle."Rob, I want to make you feel good," she said.She knelt on the bed while Rob stood before her. She unbuckled his slacks, they slide down effortlessly. She tugged at his boxes and his cock sprang out. "Unbelievable," she said."Unbelievable," I said.Rob's cock was easily 9 inches or more and the girth. I turned and started going through the process of opening the settings. And how it won't open. So she gets on her knees beside me and looks closer to the screen. And between how good she looks and her smell I get rock hard. I try to keep it hidden. And am uncomfortable. She keeps talking and I was kinda daydreaming . When she asks me why I don't answer. I apologized to her by saying that between her smell and the way she looks I'm distracted. She giggles and says do I look bad . And I. Lisa then said "Let's make dad tell who has the best ass." All three girls took off their panties and turned so he could see their bare asses. "Rub our asses dad. See who had the best one." As he rubbed each ass his cock was ready to burst out his shorts. He kept rubbing one ass after the next and going back to the first. He liked the feel of the young ass. The dad was moving too slow so Lisa took his hand and put it between her legs and closed her legs against him. Mary took his other hand and. She began a slow dance, less to imitate a strip tease than to arouse herself.And it was working. Suddenly Robin wanted to be naked for the man. Unsteady hands rose to her top. Unsure of how best to begin taking the garment off, the young teen cupped her hands around her breasts, squeezing them as she sometimes did while in the darkness of her bedroom. The familiar glowing welled within her, and she closed her eyes. Swaying her hips in wide arcs accentuated the stimulation of her tingling labia.
