We paused for about 15 minutes for a soda break and to let the pain subside on Sean's face. I did not want to detract from what he felt next, so the b...eak in our activities was necessary.The next step in my plan was to break all 12 of his arm and leg joints with my stinger. I took a foot-square piece of plywood from my kit and shoved it under his elbow. That was to make sure that the bed did not soften the blow when I hit him with my stinger. I didn't say anything to Sean as I drew back my hand. I mean, you're my sister, I'm your brother. I mean your very pretty and, in the last year or so, you really have developed, you know, boobs and a figure. There's lots of guys who'd like to, um, you know, uh..." Fuck me?" Well, yeah." You said you thought it would be okay if it was consensual, well, I consent." Geez, Dawn, I'm sixteen, you're thirteen. It's just..." Just what?" Oh, I don't know." Well, it seems that with my consent, we're half the way there." Why do you have to be so logical?". I bend forward ever so slightly, in a moment of weakness and he decisively shuts the door. Now I'm arching my back reflexively, breathing heavier and trying not to enjoy the sensation of his cock against my back side. He peels back my speedo about half way and slaps his hard cock on clammy cheeks. I'm cold in the air conditioning, wearing nothing but my damp speedo and I crave the warmth of his member inside of me. He grips me by the shoulders and steers my over to the edge of the sofa. He. ‘Anyway,’ Fran went on, ‘Gabriella stayed in her room last night and Connie’s miffed because she was going to have it. She didn’t appreciate sleeping on the sofa, and she wanted to move her stuff in from Tommy’s today. They’ve been arguing about it all morning.’ And now she mentioned it, I could hear raised female voices in the background. I felt this was an easy call. After all, it was Gabriella that had changed her mind about moving out. (True, she had had some prompting from me but I failed.
