The arrangement had gone on for many years until dad got sick. At first they just screwed each other on “dates” where they’d pretend to be other...people, but then each met other partners who usually became long term lovers. They didn’t do threesomes or swapping but Mom said that sometimes she would even have more than one lover on a given day. Answering my concern, she stated emphatically that the extra sex with others only increased her desire for, and enjoyment of, sex with my father.I told. ”Mikey worked higher, kissing her neck as his hands explored her toned back. He kissed down over her exposed collarbones and over her chest, gently sucking in the hot flesh of her cleavage between her fabulous breasts."Yeah, but doing it outside in the sun with you, knowing we could get caught at any moment, is such a rush, too," said Mikey as he traced the lines of Lauren's bra with his fingers.Lauren pulled at Mikey’s t-shirt and he let her pull it off over his head. She reciprocated, kissing. “Is there something wrong with being a virgin?” she asked. “OHHH NOOOO. NOT AT ALL” I told her and I shook my head. “So why would you ask me that then?” she asked. “I don’t know. I really don’t” I told her. I shrugged. “There’s something else. I’m not your real father.” There was a silence. She was looking down. Finally, she looked up. She didn’t seem surprised. She didn’t actually smile. She gave me this look. I liked it, a lot too. “You aren’t my dad?” she repeated. Her head was cocked.. She heard him fall back on the couch and sniff her panties before howling to Bill that there was fresh cum on the crotch! Bill laughed and started telling Duff what a dirty whore he thought she was, and saying many nasty things about her, acting like she wasn't there, it made her feel so degraded, yet so turned on! SHe then felt Bill grab the back of her head and hold her face down as he started pissing in her mouth! He wasn't gentle like Lee had been earlier, and let his built up urine gush.
