As my parents’ only son with 3 younger sisters I had to take over the father role after our dad left. It was not an easy task trying to discipline three girls. They were very wilful and clever at manipulating me into giving them what they wanted. I could handle them at first but the older we got the more it seemed they were disciplining me rather than the other way around. We were raised Catholic and my sisters went to an all-girls school called, The Immaculate Conception Academy (I kid you not). They wore those little uniforms with the white button down shirts and the tartan skirts. Of course, like me, my sisters were all over-sexed so it was a constant problem trying to get the girls to keep their skirts from riding too high. Every morning they’d start out below the knee and by afternoon they’d have them hiked way up, and the underpants would invariably get pulled up in the cracks of their asses. How did I know this about my sisters? For some reason my mom made it my responsibility to check up on them. Looking back it seems rather strange for a mom to tell her son to check his sisters’ underwear to make sure their asses weren’t showing but she worked long hours to support us all and couldn’t be there to keep an eye on them herself, so the responsibility fell on me. We used to joke around that I was the “panty guard.” It was okay at first, but as we got older, all of our libidos increased and it was harder and harder to keep the girls under control, especially when I could barely keep myself under control. My sisters knew I was having trouble, so they were ruthless and teased me mercilessly. I’ll never forget the time Allison left school without her panties or her bra on and I had to deal with her. Allison was the eldest girl and, of course, the most promiscuous, always setting a bad example for her sisters. I would meet Allison, Rachel, and Stacey at 3 pm every day at the bus stop and escort them home to make sure they were safe and didn’t get into any mischief. On this day when I arrived they were standing outside as usual talking to their friends. But I noticed Allison’s uniform was not right, so I went right up to her and scolded her. “What do you think you’re doing?” I asked firmly. “What are you talking about, brother dearest?” she sassed back. “Don’t play dumb with me, Allison. Your skirt is way too high and what’s going on with your shirt?” I said. “I don’t know what you’re talking about, Ray Ray,” she said reaching back to tighten her French braid, which made her shirt problem even more noticeable. “Come with me,” I said leading her over to the side of the building where we would not be too conspicuous. “Allison, why are your nipples showing right through your shirt?” “Where? I don’t see any nipples, Ray-Ray,” “C’mon Allison anybody can see these,” I said grabbing her nipples and holding them firmly. I’d never done that before and I didn’t intend it in a sexual way but the minute I did we both realized how erotic it was. Allison didn’t move but just stood there looking a little stunned, with her mouth open and her eyes on my fingers grasping her hardened nipples. I didn’t let go, I just kept a firm grip on them as I reprimanded her for not having her bra on. “Allison you should not have taken off your bra, it makes you look like a cheap slut and your breasts are too big to have them bouncing around in your shirt. Now where is it?” I asked still holding my sister by her nipples. “I, I have it in my purse. Why are you squeezing my nipples brother dearest? Are you trying to feel me up?” she said with a coy smirk. “Don’t be disgusting!” I said and as I did I noticed I was getting an erection. “Well you’re squeezing my nipples really hard,” she said starting to twist and pull away from me. For some reason I still didn’t let go believing I was doing it as a disciplinary measure. But thinking back I realize I was enjoying holding my sisters nipples, and the more she tried to pull away, the more I enjoyed holding on to them. She started bouncing up and down to loosen my grip and feeling her big breasts bouncing around against my hands was getting me very excited. Suddenly I released my grip on her nipples and without thinking I grabbed her breasts in my hands. “Stop bouncing them around like that, it’s not good for them,” I blurted out. We both realized how silly it sounded and how much we were both enjoying this whole scenario, and simultaneously cracked smiles at each other. It was a strange moment where we both admitted our sexuality to each other for the first time. Quickly I tried to play it down and let go of my sister’s tits. “Put your bra back on,” I said. “What? Right here? I can’t take my shirt off right here. What if someone comes over here and sees me?” she said opening her purse and taking her bra out. “I’ll stand guard and make sure no one sees you,” I said looking over my shoulder. Allison unbuttoned her shirt and stopped. I could see the center portion of her bare chest, the inside curve of her ample breast and abdomen. She was breathing heavily, excited by the idea of taking her shirt of in front of me. We both stood there for a moment. Allison was blushing and I’m sure I was too. She looked around to make sure no one was watching us. “I dare you to do that now, Ray-Ray,” she said expanding her chest to make her breasts look even bigger. “What, this?” I said grabbing them again and giving them a thorough groping while she stared at me with a wild look in her eyes. I stayed on the outside of her shirt but I let it open slightly more threatening to expose her. She let me grope her breasts for as long as I wanted to and I think I fondled them for a good thirty seconds before stopping and giving her a little antagonistic pat on the cheek. “Turn around,” she said. I turned around most of the way but kept her in the corner of my eye as she quickly put her bra back on and re-buttoned her shirt. “I saw you looking,” said Allison, “All boys like to look at my boobies, I’ve even seen some older guys get an erection from staring at them.” “That’s doesn’t happen to me,” I said trying not to let my cock pop up and show in my pants. But secretly I wanted my sister to know how she had aroused me, so I got an idea. “If you don’t believe me check for yourself,” I said. She got a big smile on her face and said “Oh yeah?” Then she grabbed my crotch and immediately her jaw dropped and her eyes got bigger than ever. She gasped and let go. “Ray-Ray!” She exclaimed, “You have a huge erection! Did you get that from looking at me?” “No!” I said emphatically. Then I looked away and said “Yes. So what?” My sister ran away laughing and I followed her trying to conceal my hard-on as best I could. We ran back over to the bus stop just as the bus was coming. Allison was still laughing and Stacey the next oldest was wondering what was going on. We got on the bus and kept looking at each other with knowing smiles and busting up. Stacey and Rachel had their curiosity piqued and they knew something funny was going on. But they got distracted after a few minutes. Allison was sitting on the sideways seat on the back of the bus and I was sitting across the aisle facing her. Rachel and Stacey were a few seats forward and by the end of the line, near our house, the bus had emptied out mostly. So as soon as we were alone Allison did something that really shocked me. I’ll never forget it and to this day I still jerk off thinking about it. She put one leg up on the seat giving me a clear view of her crotch, in broad daylight, and she apparently had left her panties in her purse too. The sight of her fuzzy little sparsely-haired blond beaver and tight pink pussy lips between those creamy smooth thighs, combined with her wry little smile with one eyebrow raised—her confidence in how sexy she looked—left an indelible image burned into my mind forever. From then on I was sexually focussed on my sister and I could hardly think of anything else. I wanted her so badly after that I couldn’t stand it, and she knew it too. I tried to play it off but the power had clearly shifted. She would tease and tempt me mercilessly and I would do anything for a glimpse or a feel. She kept me right where she wanted me for several months giving me just enough to keep me hungry but never enough to satisfy my lust for her. Until one day when circumstances happened to fall into place. Mom had gone out for the day and taken Stacey and Rachel with her. It was early on a Saturday morning and I was lying in bed thinking about Allison. I heard the shower turn on down the hall and as I laid there I heard the bathroom door open with the shower still running. Then I heard footsteps walking down the hall. I thought she might have gotten out of the shower to grab a towel from the linen closet and wondered if she might be undressed. I got out of bed and poked my head out of my bedroom door just in time to see her turn the corner into the walk in closet. She was bare-assed naked and I caught a momentary glimpse of her jiggly pale buns glistening with soapy water. I was so excited I stared down the hall waiting for her to walk back, but when I saw her turn the corner with a towel wrapped around her, I quickly ducked back in hoping she hadn’t caught me spying on her. I got back in bed and got under the covers with my cock rock hard and started stroking myself thinking about what I’d just seen. I was getting close to cumming when I heard my sister scream! I stopped mid stroke and listened. “Ray! Ray!” Allison called out to me, her voice sounding panicked. I got out of bed and slipped on a pair of boxer shorts but my erection was making a serious tent in front. “What’s the matter Allison?” I called back from down the hall. “Com’ere Ray! Quick!” she shouted. The bathroom door was slightly open and I slowly entered. My sister was standing against the wall naked, wet, barely covering herself with her hands. I was mesmerized and stared at her as she pointed at the shower stall with a look of terror. “Wh-wh-what’s wrong, Assall-Allsa-Allison?” I stammered barely able to speak much less think. “Sp-i-i-id-e-e-er!” she whimpered. I looked in the shower stall and saw a medium sized daddy-long-legs on the wall. I turned the shower nozzle on it and washed it down the drain. “All gone,” I said, and as I turned around I saw my sister standing fully naked, arms at her sides right in front of me. She made no attempt to cover anything; it was all there. Her big D-cup tits with perfect nipples pointing straight forward fully erect atop scrunched up areolas; her smooth flat belly tapering down to her neatly trimmed blond pussy with little lips peeking out from the slit; her muscular thighs slightly apart, as if she was ready to bolt, but she didn’t move. My eyes devoured this glorious sight and slowly moved up to her face which was still reflecting fear, but as she realized the spider was gone, and saw me staring at her amorously, her face softened, first to a grateful smile and then to a sexy seductive look that made me feel dizzy for a moment. We stood there for what seemed like a long time. Then she reached her arms out to me, walked forward and pressed her bare tits against my abdomen, then she wrapped her arms around me tightly. As she laid her head against my chest her hips moved forward and my erection pressed against her belly. I could feel the head of my cock slide down to meet the warmth of her pussy. “Thank you Ray, I think I owe you one,” she said softly in a sexier voice than I’d ever heard from her before. “Owe me one what?” I asked not really aware of what I was saying. “Hee hee! What would you like?” she giggled as her hands slipped down the back of my shorts and grabbed me firmly by the butt cheeks. “I can’t imagine anything better than this,” I said choking slightly on the words. “I have an idea,” she said as she took my hand and pulled me into the hallway toward her bedroom. “I think I should let you have my body to make love to in any way you want, for as long as you want. How does that sound, brother dearest?” she said as we entered her bedroom. “That sounds like a dream come true,” I said, “but you’re more than just a beautiful body to me. You’re my sister. I want to make love to my sister, not just her body.” “Oh my gosh! I can’t believe you said that,” she said with a strange look on her face. “No, no I didn’t mean that as a bad thing I, I’m sorry,” I tried to explain. “It’s okay brother dearest, that was a beautiful thing to say, I don’t know why I was surprised. You said exactly the right thing,” she reassured looking deep into my eyes. Well you said exactly the right thing too, in fact I’ve had fantasies about you saying that to me. The problem is, now that you’ve said it, I don’t know what to do. I’ve never made love to anyone before,” I confided. “Ha ha! It won’t be a problem, Ray. I promise you it won’t be a problem at all,” she said as she guided me to the foot of her bed and pushed me onto it. “You like my boobies don’t you?” “Like a squirrel likes his nuts,” I said. “Well I need them to be played; I need my nipples pulled, and twisted, and sucked even. Would you mind doing that to my nipples, brother dearest?” “Okay,” I said as I began fondling my sisters amazing tits. She climbed up on the bed and straddled me sitting right on top of my cock, which was aching to get out of my boxers. The feeling of her warm buns on my lap was ecstasy and I instinctively started pumping my hips. My hands were all over my sister’s body. She felt so good to me I never wanted to stop touching her. The look on her face throughout all of this was unreal. I’d never seen her look so beautiful. There had always been a little tension between us, call it sibling rivalry, but there was none of that now and I felt nothing but love and warmth from my sister. We shared something in common that went beyond mere carnal urges. We knew each other so well, it was like we had the same desires and together we were completely fulfilled. All I knew was I felt closer to my sister than I’d ever felt to her, or to anyone. I pulled her toward me to give her a hug, to thank her for letting me have her in this way. I moved my head aside but she followed my face with hers and our mouths touched. I was confused for a moment. Was my sister intending to kiss me? I didn’t move and just felt her lips press against mine. We stayed that way for a while and I could feel her breathing become heavy and hot. Her tongue licked my lips and she pressed her face into mine hungrily, sucking my lips, pushing her tongue into my mouth and even biting my lips gently. She was moving so fast I just let her lead and followed along. It was so erotic I thought I was going to explode. I pulled away momentarily and my face showed her the intensity of my desire. “I know what you need brother dearest,” she said as she climbed down off of me and lowered her head between my legs. In one motion she pulled my shorts off and tossed them onto the floor. “Oooh! The lord was good to you!” she said excitedly and grabbed my throbbing cock in her hands. I’d never in my life felt anything so good as my sister’s hands on my cock but what she did next felt so much better I though I’d died and gone to Heaven. This story is about to go to a whole other level and in the next chapter I do things with my sister I didn’t even know were possible. So if you want to read the rest, let me know and vote Awesome.
