The next two weeks after the river went about as you could imagine. Charlie's sex drive was insatiable and it was common for him to cum five or six times a day. We had sex just about everywhere throughout the house; from our parents' bed to the kitchen table. We still enjoyed hanging out all day, but there was an inseparable sexual element in our relationship by that point. A side benefit of our relationship was the open attitude towards nudity in our house. It was rare for either of us to wear much in the way of clothes unless we were going anywhere, and that meant I could sunbathe in the back yard completely nude for a change. Our parents had an eight foot privacy fence around the entire back yard, and I thought that that would be enough to prevent anyone from seeing in, especially since both of our neighbors had single-story houses. What I failed to account for was that the neighbor to our right, Mr. Donaldson, had an attic window that faced our house. Mr. Donaldson was your typical reclusive old neighbor: he was a retiree, he kept his yard in immaculate condition, but he was rarely seen outside otherwise and didn't interact much in the neighborhood. From the times I'd seen him working in his yard I guessed that he was in his late 50's with an overall thin build, grey, thinning hair, and a mustache. He'd always given off a creepish vibe, but I'd never had anything concrete to confirm it. One afternoon, after giving Charlie another blowjob to hold him over, I went outside with a towel and spread it out in the middle of the back yard. The hot summer sun felt amazing on my bare skin as I lay there and rubbed some lotion over my body. I put my earphones in to listen to some music and had almost drifted completely off to sleep, with my eyes almost closed, when I saw a flash of light come from the attic window that I hadn't noticed before. I opened my eyes fully and glanced over just in time to see a shadowy figure disappear from the window. My heart nearly skipped a beat. Part of me wondered if it had all been a trick of my mind; just a glint of sunlight and the shadow of a bird, but the more I thought about it the more certain I was that I'd seen the figure of a man. And even more, I began to wonder if the flash I'd seen had been from a camera. A few weeks before the idea would have completely creeped me out, but by that point the idea of a pervish old neighbor spying on me sent an exhibitionist thrill through my body. I continued to lay there, watching out of the corner of my eye for the figure to return. Sure enough, like an animal that was spooked but still curious, I saw movement behind the window. If he was brave enough to spy on me, then I decided he deserved a good show. I spread my legs slightly and brought my hand to my mouth. Sliding two fingers in, I sucked and licked them, getting them wet before sliding them down along my body to my increasingly wet pussy. It was the first time I'd masturbated as a stranger watched from a distance, and even after the exhilaration of my experiences with my brother, the thrill that ran through my body as I rubbed my clit was unbelievable. A soft moan escaped my lips as I closed my eyes and arched my back. I plunged two fingers deep into my cunt, feeling my tight muscles grip them and leaving them coated in my juices as I pulled them out. In and out they went, bringing me closer and closer to an orgasm as I saw more flashes come from the window. It wasn't long before the orgasm crashed through my body, causing me to moan out in pleasure in the summer heat as I came for my pervish neighbor. After I'd recovered from the powerful orgasm, I licked my fingers clean and went back into the house. I'd never imagined that voyeurism and exhibitionism would be a passion of mine, but after cumming so hard I had no doubt how much I loved it. Charlie and I hung out for the rest of the afternoon, but for some reason I held off on telling him about our neighbor. I knew he'd be interested, but for the time being I wanted it to be just my little secret. Charlie and I ate dinner and then he went back to playing video games while I cleaned up in the kitchen. I noticed the trash needed to be taken out, so I slid on a pair of shorts and a spaghetti strap shirt. The timing couldn't have been more perfect as Mr. Donaldson was just doing the same thing. I smiled at him and waved as I walked down the driveway to our trashcans which were sitting side by side. I could see him blush as he clumsily waved back. "Hi there," I said as I put the trash in the can. "Amazing weather, isn't it?" The question, actually the attempt at starting a conversation entirely, seemed to have caught him off guard. He nodded and stammered a little. "Y-yeah, kind of hot though." I shrugged as he put his bag of trash in his can. "That's true, but I've always loved the summer." He was struggling to keep his eyes from looking down over the body he'd seen nude just an hour or so before and it was clear that conversation with strangers wasn't his strong suit. "I guess. I'm Jim. You're their daughter, right?" He asked as he nodded at my parents' house and offered his hand. I nodded, "Yeah, I'm Cassie." I said as I shook his hand. "I'm just baby-sitting for my brother while they're out of town." He nodded, "I think I've seen him around a few times." Either he didn't immediately question why I would be sun-bathing nude in the backyard with my brother at home, or he didn't care, but either way it didn't come up at the moment. "Anyways ... it was good to meet you." He said before turning around and walking back towards his house. "You too," I called out as he walked away. I smiled a little as I walked back to our house and thought what a strange man he was. The next day, at least when I wasn't getting fucked by Charlie, I thought about our neighbor. I wondered if he'd be in his attic this afternoon as well and decided that I'd go out to tan at the same time again. I left Charlie in the living room, engrossed in another on-line game, as I went into the back yard. I laid out the towel once again and inconspicuously glanced up at the window in our neighbor's house. My pulse raced when I saw the distinct upper body of a man within it. Knowing that my pervish neighbor was watching once again had me cumming within minutes after I laid down on the towel. Over the next couple of days I stuck to my new routine with the indoors occupied by my brother, and putting on a daily show in the back yard for my neighbor. That Friday, however, Charlie wanted to go to a movie so I missed my regular afternoon 'show.' We ended up eating dinner out as well, so we didn't get home until close to seven that evening. Charlie immediately hopped on his video game and I knew he'd be occupied with that for a while. I, on the other hand, was flirting with the idea of going over to the neighbor's house. I know it might sound strange, but I didn't want to make him think I'd just decided to stop all of a sudden. I didn't think about it too long and decided to go through with it. I told Charlie I was going to the store which he acknowledged without paying too much attention. I walked out the front door and across our driveways to his front yard. It was funny feeling a sense of nervous excitement just to talk to someone that had been watching me masturbate for days now. As I walked up to his front door I looked over my reflection. I was wearing a pair of tight, low-cut denim shorts and a white tank top with a white bra. I rank the doorbell, but noticed that I couldn't see any lights on inside. If it weren't for the fact that this car was in the driveway I would've thought that nobody was home. It took a while, but finally he came to the door, opening it just a little and leaning his head out. "Oh, it's you." He said matter of factly as he saw me. Not coldly, just a little surprised. I smiled, "Hi, um..." I realized I hadn't even thought of what I was going to say, so I decided I should just be straightforward, "I just wanted to say sorry that I wasn't around today." He did a pretty good job of feigning confusion. "I'm not sure what you mean ... I don't think I was expecting you." I laughed a little, he wasn't going to make this easy. "What I meant was I'm sorry I wasn't in my backyard this afternoon..." His continued stare of confusion almost made me question whether I'd imagined the whole thing, but I was certain, " ... I know you watch me from your attic." His eyes darted to the road as if he thought it was a set-up or something and he began to close the door, "I'm sorry, I think you're confused." I put my shoe in between the door. I've never been so aggressive, but I didn't like the fact that he was so blatantly denying it when we both knew what happened. "Mr. Donaldson! I was masturbating for you." I said emphatically. Wanting to make the point very clear that I'd done it intentionally. I saw the realization dawn on his face as he suddenly stopped and looked up at me. "You ... knew I was there?" I nodded and shrugged, "Yeah." He looked at me quizzically, "Why?" "I guess it was just a turn-on ... knowing somebody was spying on me." He looked down, seemingly in thought, "Oh ... um ... would you like to come in?" "Sure, thanks." He opened the door and let me inside. As I walked in, I was surprised by how dark and cluttered it was. He led me into a living room, with two couches facing each other, and I could see a feint light coming from a room down the hall. "Please, have a seat." He said as he sat on the opposite couch. "I thought you'd seen me the first day, but when you um ... continued, I thought I was safe." I smiled a little, "Yeah, I saw the flash & then saw your figure. My little brother wanted to go to the movies today, so I wasn't able to be out there. Since I missed our 'show' I just thought I'd stop by and finally say 'hey' for real." I could tell he was quickly warming up to me. Maybe it was because he realized I wasn't trying to entrap him, or maybe because he recognized a fellow pervert. "Well thanks, I remember when you were still in high school, you were..." He trailed off, apparently catching himself. I smiled, "You remember me from high school? Gee's, how long have you been spying on me?" I asked, but obviously not in an offended tone. Realizing that he wasn't getting himself in trouble, he continued. "Well, you and your friends used to sun bathe in bikinis in high school. I remembered how good you looked back then, so when I saw you were in town, I waited to see if you were ever going to sunbathe again. I'd been waiting up there on & off for weeks." The more he talked, the more he seemed to relax and open up. By the time he finished his last sentence he was actually smiling. "Oh my gosh ... weeks?!" I laughed, but not in a mean way. "I feel terrible!" He shook his head, "Not at all! I got more over the last few days than I'd ever imagined!" I grinned, "Well I'm glad it finally paid off for you. So, if you don't mind me asking ... were you masturbating up there when you saw me?" He shook his head, "Oh, no, I was..." I saw him hesitate again, but he finally pushed on, "to be honest I was filming you. That way I can take it to my computer, enhance it and get a better view to jerk off to." I grinned, "So you're pretty good with computers and cameras, huh?" His face seemed to light up, "Come here, I'll show you." He led me down the hall to the source of the light, which was a small room. As he opened the door fully it was pretty clear what he used the room for. The shag carpet floor was covered in cum stains and the smell of it was heavy in the air. But the main attraction was a computer with a large monitor on a small desk. One wall had a small, raggedy looking couch and the other was a shelf full of burned DVD's with I don't even know what on them. He pulled up another computer chair as we sat down at the desk. He browsed through some files until he reached mine. I watched as a video began to play, clearly showing me fingering myself on the first day. "Oh my gosh," I said, impressed, "I can't believe how clear it is." He smiled at the compliment. "Thanks, it's a pretty good set-up I have." He looked over at me, his eyes running over my body. "Still, seeing you up close is even better..." I looked over and saw the hungry look in his eyes. After watching me for so long, it was only fitting that he should get to have me. I stood up and took his hand. He was at least three or four inches taller than me as he stood up and I led him over to the couch. He pulled his shirt up and over his head, revealing a hairy grey, thin body as I dropped to my knees and undid his pants. They fell around his ankles and he stepped out of them before I gripped his boxers and pulled them down. A 5 -- inch hard cock sprung up, surrounded by a thick grey bush. He sat down on the couch and spread his legs as I crawled forward in between them. I took his hard cock in my hands and gently stroked it, marveling at how hard it was. "I've cum to your face so many times ... I can't believe you're on your knees for me..." He said, breathlessly as I stroked him. "Mmmmm, you're going to feel all of me tonight, Mr. Donaldson." I leaned forward and slid my mouth over his cock, easily taking it all the way in until I felt my nose buried in his thick hair. He moaned as my head bobbed up and down in his lap. "Yessssss, that feels so good Cassie! Suck my dick you little slut!" He groaned. I moaned onto his cock as I felt my chin press against his warm balls, over and over again until I was certain I'd given him enough oral pleasure. I took my mouth off and gave the tip of his head one more kiss before standing up and stripping completely naked infront of him. "Are you ready to fuck my pussy Mr. Donaldson?" I asked sweetly as I climbed onto his lap. "I-I don't have any condoms," he said as he looked down at my glistening pussy with an almost enchanted stare. "Mmmm, you can cum inside me ... I want you to." I said. Reaching down between our legs, I gripped his saliva-coated cock and guided it to my slit. Looking into his eyes, I dropped down onto it, feeling his hard cock penetrate me. "Ohhhhh fuck! Mmmm your cock feels so good inside me!" I moaned. His hands gripped my hips as his head rolled back and he let out the most blissful moan. "FUCKKKK! Ride my cock with that tight wet cunt of yours!" He groaned. I began to bounce in his lap, my breasts bobbing and swaying as I rode my neighbor's cock. He was the oldest man I'd ever fucked by that point and I loved the fact that he'd known me for so long. "Mmmmm, fuck my tight little cunt, Jim! Fuck it like you've wanted to since I was a girl" His eyes were wide with lust as a dream that he'd had for years finally came true. He thrust his hips up at me as I came downwards, slamming his cock into my pussy and meeting each thrust. I was soaking wet and my juices had already matted the hair around his cock. We were both lost in states of unbelievable ecstasy as our bodies writhed and slammed against eachother. Finally he couldn't hold out any longer. "I'm getting close, Cassie!" He groaned. My own orgasm was approaching quickly and I wanted them to be simultaneous. "Mmmm, I'm so close ... cum with me Mr. Donaldson! Pump your cum into my tight cunt!" His hands roughly groped my breasts as we both reached our thresholds. My pussy began to spasm around his hard, throbbing cock just as it began to ejaculate it's thick load inside my unprotected cunt. We both screamed out, bucking and thrusting against eachother as our orgasms crashed through our bodies. It was over almost as soon as it began and I finally collapsed against him, my head next to his with my breasts pressed to his chest while we slowly recuperated. "That was ... incredible," He panted. I grinned and leaned back, "You were amazing!" I said as I slowly rolled off of his lap and next to him on the couch. He stood up and went to a shelf, fetching a camcorder. He turned it on and walked back over, filming me as he did. "Smile for the camera," he said in a cheesy voice as he zoomed in on parts of my body. I laughed and spread my legs wider as he began to film his cum leaking out of me. I slid a finger in and pulled it out, fully covered in his load, and brought it to my mouth. I sucked his semen off of it, savoring the taste of his cum. "mmmmm, you taste amazing Mr. Donaldson." "Well there's more where that came from, little lady. And you're welcome to it whenever you want." I grinned, "I'm going to take you up on that, you know." He stopped filming and had a seat in one of the computer chairs. "I hope you do." I walked over to the other computer chair and had a seat. "So, am I your only model or do you have others?" The grin on his face told me all I needed to know. He began with the ones that he'd filmed personally. Peeping tom shots of high school girls in their underwear, cheerleaders in various poses from afar, local women from the neighborhood whom he'd filmed from just outside their windows and more. He also had a collection of things he'd obtained on the internet, including high school girls being paid to have sex with adults, and other things of that sort. Each time he showed me something new there would be a slight hesitancy, but as I embraced every fetish with more and more enthusiasm he became increasingly excited to show me more. For nearly an hour he showed me all of the things he'd obtained, but there was something I'd noticed that he didn't have, and something that I was certain he would love. "Mmmmm, this is amazing! I can't wait to see more, but I know Charlie's going to be wondering where I've gone off to." I said as I checked my watch. He nodded, "Well stop back by any time." "Oh, you bet I will," I said with a grin, "and I'm going to have a surprise for you too." He looked excited, "A surprise?" I nodded, "Have your best equipment in the attic tomorrow at 3:30 pm. I promise you won't be disappointed."It Started With My Little Brother - Chapter 4 - Neighbor, voyeur, creampie, blowjob
