I came into the other room. As I walked in, Kayla pulled off her t-shirt and her shorts. I stood there looking at her in a pair of peach panties and a... matching bra. And almost instantly, I felt my dick getting hard. Kayla sat on the couch watching us. One thing led to another. Julie's panties came off. Her bra came off. My boxers came off. My dick was throbbing and massively hard. I was shaking. I couldn't believe it could happen. That I could really fuck two sixteen-year-old girls in my. We had a very good automatic testing lab that could find anything harmful to us in our food, so she wanted to gather some representative samples and test them for safety. I certainly agreed with the idea, but I insisted that we never go anywhere alone until we knew much more about our neighborhood. Lucy was not enough protection, I was going along to cover her with the RPG.We hitched Linda to the wagon and went out prospecting for food and anything else useful that we could find. We headed down. ‘You really are quite attractive, Betsey,’ he said softly as he began to trail his fingers lightly up and down her bared back. ‘Ah…’ Betsey murmured. She had no idea what to do, or say. She could hardly breathe and coherent thought was beyond her. Things had gotten way out of control. ‘You’re excited, aren’t you, Betsey?’ Mark asked softly, continuing to gently stroke her back. ‘Uh-huh,’ Betsey murmured. Why was she letting him do this? Why wasn’t she stopping him? Why did it have to feel so. I spotted the dark haired dancer, and felt myself getting stiff as she captured my attention. As the spotlights shone, her breasts were highlighted by the darkness behind her. It was obvious that she did not wear a bra, as the well rounded mounds jiggled against the clinging fabric. Her legs were bare, made taut by the earthy dancing. I asked myself if she was wearing knickers, and found the thought of her naked beneath that dress made me start to sweat with desire. I actually felt light headed.
