As we headed back in, she was right next to me with her arm around mine, stating she needed to keep her balance. I didn’t mind because her bob was a...so resting on my arm and her nipples were sticking way out. I wanted to reach over and pull her top down and bite one of those nipples. Once we got back in, I tied us up and said I could come back later and cover the boat. She went over to the pay phone and order a pizza from the shop near her place.On the drive back we were laughing and talking. My stepmother Mary was an attractive 32-year-old woman, who had one daughter from a teenage pregnancy and I was pretty sure was a gold digger, though I had nothing to back it up. It was just a feeling. She married my dad when she was 25 and he was 38. That was 8 years ago. In that time I learned that she was nice enough as a person. She loved the outdoors and shopping, odd combination, I know.Her hair was golden blonde and it was usually let loose like a waterfall. She was five seven with long. The same panties that I had ripped off of her, to reveal her sex and to enter her body. I reached over and grabbed them.I held Nikki's underwear in my hand as a trophy as my cock thrashed into her."Open your mouth," I told her.Nikki did as she was told. I reached down and shoved Nikki's dirty undies into her open mouth, stuffing them inside with my thumb. Nikki didn't resist.Nikki laid on the bed and took my cock inside of her, with her used panties in her mouth. I stared down at the slut. Why would you want a young inexperienced college girl when you could have me?’ Mia teased as she finished pulling his pants off. David’s cock sprang to attention. ‘I’m sorry Mia–I got seduced by her innocence–like the guy in the Nabokov story–only she wasn’t very innocent.’ ‘Tsk, tsk,’ Mia reprimanded him just before sliding her mouth over his dick and down the shaft of her throat. ‘Ohhhh, Mia. Suck my cock!’ David’s eyes closed as he leaned back in his chair. Mia obliged and her head bobbed up.
