I awoke with a start (for the second time that morning). This time it was my door banging open as my sister Angie stormed in. The clock said 9:20. I had gotten home last night at 4:45. "Jesus, what!" I exclaimed. I had fallen into bed naked. In my warm room during the night the sheet had slipped almost completely off and now I was covered by just a corner. "Your girlfriends are out again." "What? So?" "So don't you want to watch them again?" "Maybe. But I'm sleeping. What do you care?" "I want to watch." My cock sprang to life under the sheet. Had I heard that right? She closed the door and moved to the window. "Oh. My. God," she said melodiously. "What?" "You'll have to see for yourself," she said, and stepped to one side, inviting me to join her. "Christ," I mumbled under my breath, and kicking the sheet to one side, stood next to her, naked, my cock now long and thick and standing out from my body, maybe three quarters erect. When my eyes fell on the two Blossom asses wiggling in the yard across the street, my cock jumped to full rigidity, pointing up into the sky above the Blossom household. "Wow," Angie said, glancing sidelong down at my pole. The Blossom mre and fille were wearing matching tennis skirts, white and pleated. Both skirts were entirely too short, not even in the neighborhood of appropriate, or had been hiked up, the hems of each ended maybe an inch below where their ass cracks started, so their entire asses, wide and narrow, were exposed. Both pairs of knees were spread wide apart, and both backs were arched as they dug weeds out of the flower bed, pushing their asses and pussies backward between their thighs. The Blossom mre was wearing a white string bikini for panties, so that the wrinkles of her mature but apparently hairless asshole were visible to either side, and only the narrowest triangle of cloth wrapped around those big pussy lips that I had noticed yesterday evening. As fantastic as Mrs. Blossom looked, truly a spectacle any of my magazines would have paid dearly for, her nine-year-old daughter had her beat, for Cynthia had forgone panties altogether. Her hairless, puffy pussy lips and flawless butthole were spread open between her narrow little ass cheeks. Her butthole was so smooth and perfect that it was difficult actually to see it at all from this distance. The slit between her cunt lips was stretched open enough to see the still featureless pink between them. Both the Blossom asses gyrated seductively as they stabbed at the ground with their garden trowels. "Look at that little pussy," Angie said to me. "Isn't it weird that that narrow little thing is going to grow into that sexual siren on the right?" she asked. "I wonder how long it will take," I replied. "You're not developed like that yet, are you?" "I am fully developed, thank you very much. I just don't look like a whore." "Are you kidding? Mrs. Blossom is hot." "I think you have a thing for the other one." My cock twitched. "Whatever," I retorted. "Wow, look at that," Angie said, glancing down at my cock again, where a big glistening drop of pre-come had oozed out of the tip. "So, will you let me watch?" she asked me seriously, not teasing anymore. "Sit down on the bed," I told her. She obeyed, then stared at my hard cock now twitching at eye level. I nudged my leg between her knees so she would spread them apart, and stepped between her thighs so my cock hovered just a few inches from her face. My sister is a beautiful girl, but plain. She has long straight auburn hair, warm brown eyes, and a beautiful wide mouth that has this sexy thing it does when she is nervous or embarrassed, smiling and nibbling her lower lip on one side, which it did now as she sat looking up at me. I actually didn't know what her body looked like. She was much more shy about her body than I was, never going swimming in the summer, never wearing tight clothes, or even racing from bathroom to bedroom in only a towel. Since we were little I had only seen her fully dressed, and here I was standing above her completely naked, my throbbing cock floating before her eyes. "Okay, you have to help me," I told her. "Spit on it." I marveled at how my adventures with Cynthia had changed me. Although I was a push-over with the girl, the experience had given me a demanding arrogance at times with other girls. I loved it. I had gained some confidence that these women responded to. I had lost any fear I had once had about telling a girl what to do. "What? No! Use your Vaseline!" she protested. "Do you want to watch me? Then you have to do this. Just dribble some spit onto the end. That's all." I bent my knees slightly and pushed the end down below her chin, and she tilted her head down and pursing those amazing lips let a long string of saliva slide down onto the head of my cock. I slowly spread the spit over the entire shaft as she dribbled more onto the end. "That's good," I said softly; "you're good at that." "Okay, you ready?" She nodded, eyes wide. I returned to the window to look down at the Blossom asses still wiggling and spread in the yard across the street. I imagined myself down there behind them, sliding my cock into one asshole then the other. I imagined my sister down there with them, and taking my turn with her ass as well. In no time I felt my orgasm begin to move up my legs toward my crotch. Angie was sitting there staring at me breathlessly, those pretty lips parted. I stepped back over to her, between her spread knees, and slid my fist up and down the shaft slick with my sister's saliva. "Here I come, Angie," I said softly as the first stream of come jolted out of my cock and between Angie's eyes. A breathless "oooh" escaped her lips and she tilted her face toward me like someone first stepping into a shower. My come splashed against her cheek and her nose. As the spasms subsided I placed the head of my cock against her parted lips as the last of my come oozed out of my cock and onto her waiting tongue. She opened her eyes again and grinned at me, threads of my come stretching across her lips. "Damn, that was awesome," she said. "Thanks, brother." With that she stood and walked out of the room, glancing back only once at me standing there naked with my cock wilting in my hand. I thought she had enjoyed it, but she took off so fast--had she just been toying with me? I heard the bathroom door close and a moment later the bath begin to run. I pulled on some shorts and a shirt and tiptoed down the hall to the bathroom, the only room in the house with a lock on the door. I tested it quietly but of course she had locked it, as we both always did. Fortunately I knew how to stick a paperclip into the hole to unlock the knob, which I did now. I quietly pushed the door open and stuck my head inside. "I knew it!" I exclaimed. She was flat on her back in the tub with her feet up on either side of the faucet so the water was falling heavily right onto her pussy. "Nathan!" she cried, "I'm telling!" She immediately realized how stupid that sounded and shut up. I chuckled and closed the door again so she could have her privacy.
