I could lean back a little and watch under the stall wall. He lowered his head and swallowed my whole cock down his throat. Just the sight of a grown ...an between my knees swallowing my cock was so incredibly hot I almost came but I was able to hold back. I reached under and held the back of his head and started fucking his throat in slow long strokes. When I felt I was about to cum I pulled out. I didn't want to cum until I had a chance to feel his cock buried in my mouth.I slid back on my side. While our parents remained the monsters-held-in-common, a base unifying force, I came to understand my siblings in a different light. The only thing that separated me from them was a bit of distance. With Barry, that distance would probably remain insurmountable. While Sarah and I moved around our room in just our skivvies, trying on various outfits for dinner out. Sarah had me laughing, and marveling that--in all but superfluous sense- -I had a big sister for the first time I could remember.. Her breasts were large. She was a BBW, but not huge. I guess full figured would be an apt description. She had a very cute face. I thought she was beautiful.We got down to business pretty quick. She told me to pull my cock out and start stroking. I did. She sat on the bed beside my and leaned over to take a good look. Her breasts appeared to be plunging out of her top as I looked down her top. That view made my cock even harder. I was stroking furiously and reached down her shirt to play with. " Neil is all right. You don't know him like I do." It was a common litany of mine, sticking up for Neil. People were always telling me that Neil was irresponsible, that he was nothing but trouble.We had an awkward moment. Anne looked around the room and sighed. "So what are we going to do here?" she said."Look, you don't have to do anything with me if you don't want to," I said. This was another conversation I often had, letting the second-place girl know that I didn't expect her to fuck me.
