Peeping with a Friend

When I was young, I lived next door to a family that had a daughter about my age and a son a few years older. I didn't really know them that well, but I saw the boy, Phil, often. This was mainly because I could see into his bedroom from the window in mine. I admit, I spied on him often, but it didn't start out as anything dirty. I started spying just because he was the cool high-schooler next door and I wanted to know what his life was like. Most nights, I didn't see much more than him playing video games, but it entertained me nonetheless. Then, one day, I saw something a lot more exciting. Usually, Phil would close the blinds in his room before he went to bed. On the day in question, however, it seemed to slip his mind. Instead, he began pulling off all his clothes right in front of my eyes. I knew I should stop watching, but something had rooted me in place. Next thing I knew, he was fully naked. I tried to stop myself, but my eyes seemed to have a mind of their own, and I found myself staring at his cock. It was bigger than mine, and had more hair, but I assured myself it was only because he was older than me. I fully expected Phil to pull on some pajamas at this point, but he just lay back on his bed. Was it just me, or was his cock getting bigger? Butterflies lept in my stomach as he took his cock in his hand and started stroking. I could feel my own cock responding to the show in front of me. It was straining painfully against my pants, so I took them off to give it more room. It felt amazing letting it hang loose, but whatever I was feeling was nothing compared to what Phil seemed to be experiencing. His eyes were closed tight, and his whole body was squirming. I am sure he was moaning, but I couldn't hear it from where I was. Finally, his whole body stiffened and I would see something shooting out of his cock. Wait... I had heard about this from the other boys at school. Was this what masturbating was? I didn't have the nerve to try out what I had seen on myself, but that didn't stop me from thinking about my private show. I wanted to see Phil do it again, but I knew I would probably have to wait a while for him to forget to close his blinds again. So imagine my surprise when I got a repeat show not just the next night, but every night after that for the rest of the week. I had to share this with someone, so on Friday I invited my friend Dawn over to spend the night. I didn't tell her what we would be doing, only that she was sure to enjoy it. That night, I was so excited I could hardly sit still. Dawn, too, could barely contain her excitement, and she didn't even know what was about to happen. Then Phil started getting undressed, and her eyes widened. "Should I close my eyes?" she asked. "No! This is what I wanted to show you," I said. She looked like she was about to say something else, but stopped herself the moment Phil's underwear came off. Her face was red, and she was giggling uncontrollably, but I noticed her eyes were glued to his cock. "Is this the first time you've seen a boy naked?" I asked her. She merely nodded, unable to get a word out through all the giggling. Then Phil was lying on the bed with his cock in hand, and her giggles died off. I didn't think it possible, but Dawn's eyes got even wider. I noticed that her hand was subconsciously toying with her nipple (which was clearly visible through her shirt). At this point, my cock was straining to be free, but I didn't want to risk scaring Dawn off, so I decided to just live with the discomfort. Dawn was apparently having troubles of her own, as she had to cover her crotch with her free hand to hide the wetness I had already noticed growing there. I couldn't wait to see Dawn's reaction to Phil cumming, so I was disappointed when he stopped stroking before he reached his climax. Instead, he stood up and opened his door. My mouth fell open when I saw his younger sister, Janet, standing in the hall. She did not seem surprised by either his nakedness or his erection, and just strode silently into the room while closing the door behind her. Then she started stripping, starting with her top. Her tits were gorgeous, not huge but not tiny either. Then her panties dropped and I was looking at her shaved pussy. I knew that I would have to take care of cock soon, as it was growing even more. I glanced at Dawn and was shocked to see that her hand had now found its way under her shirt and was furiously working at her tit. I took that as a good sign. "Is it okay if I take off my pants? It's just that there isn't much room left in them anymore," I said. "Sure," she said between breaths. "I think I will too. Wet underwear isn't very comfortable." I didn't even pretend not to stare as she slipped out of her panties. She had some pubic hair, but it wasn't nearly the full bush it would later become. I briefly wondered if she cared that I was looking at her before I realized that she was probably too busy looking at me to care. She also finally seemed to become aware of the hand playing with her nipples and removed her shirt to give it easier access. This left me with an unobstructed view of the most amazing tits I had ever seen. They weren't much more than buds, and they never really got too much bigger, but I was in love with them. I wanted to take them in my own hands, but I didn't have the guts quite yet. I hadn't really noticed, but I was playing with my cock now. I felt like I should've been embarrassed, but seeing Dawn's finger buried in her pussy helped get rid of that notion. I was close to cumming before I decided to check out the scene that had brought about our mutual masturbation session. For some reason, I wasn't even surprised to see Janet sucking on her brother's cock. But it did give me an idea, and I stopped stroking myself right before I came. I looked over at Dawn and saw that she was thinking the same thing. Next thing I knew, her mouth was on my cock, and I was in heaven. I must've been the happiest guy in the world, having the most beautiful girl I knew kneeling naked in front of me with her mouth full of my cock. There had been too much excitement that night, and I found myself cumming almost instantly. I thought Dawn would be grossed out, but she swallowed without so much as a grimace. I was spent, but Dawn was trying to return my attention to the other room. I saw Phil eating his sister out, and knew Dawn was ready for me to do the same. As I tickled her clit with my tongue, I let one hand sneak up to caress her tiny tit. She was moaning now, but not loud enough for our parents to hear; this intimate sound was for my ears only. And then I felt Dawn tense up beneath me and I knew she was cumming. It was the most amazing thing I had ever seen. Her whole body was trembling with pleasure and when she was done, she had the biggest grin on her face. "I love you so much," I said. This caused her sit up and plant a huge kiss right on my lips, not caring that they were still covered in her juices. "I love you too," she whispered. I would have happily spent the rest of my life in that spot, completely naked and wrapped in her arms, but something made me look out the window one more time. Imagine my surprise to see that the brother and sister who had seemed so ignorant to our spying were now waving at us through their window with huge smiles on their faces.
