As he put the key in the ignition, Brandon stopped, his priority now to discover what had brought his sister so far down so quickly."What's going on, ...ip-squeak?" he brought the discomfort to the fore."Nothing's going on. I'm just trying to get a loose end taken care of, that's all," she tried to dismiss his intrusion into a private part of her life that she was scared to reveal, especially to him."Nice try, Sis," he refused to accept her dismissal, "but whatever it is, it's dragging you down,. Tears formed in her eyes, “I don’t think I can take this much more. My physics is ruined! My brain hurts.”He laughed.Suddenly, she too started laughing, loudly, explosively, gut-wrenchingly. Happy! Happy! Happy!“Atarah! WHAT are you doing? ATARAH!” he grabbed her, holding her tight.She looked at him, puzzled. Her laughter stopped the instant he touched her. Her side ached.“I need to take you down to Med,” he didn’t give her a choice.The Auto-Doc found stressors and gave her fluids to counter. I was wondering do you wanna have some fun just the two of us? he asked shyly. I smiled with delight at his sudden push towards sex. Ok Jeremy, come on. I said as I got up and started to head towards the bathroom. I turned around for a split second to see Jeremy sitting on the edge of the bed with his cock sticking up making a tent in my pajama pants. I smiled and turned around and started to walk towards the bathroom again with Jeremy not far behind. I got to the bathroom and waited for Jeremy. I was really excited when it arrived, eager to see if it was as good as I remembered it. But sure enough, it was. I enjoyed it, so much fun to sit on the little horse, bounce with it, get that distinct smell of rubber.But I wanted to know, whether I was the only crazy one who liked inflatable toys... but luckily on the internet I found some others. Especially into Rody horses there are not many, but a few have developed a liking as well.We exchanged ideas and due to this I did some experiments.
