Well as you might guess, this is about my sister and me. I will just call her Sandra. I don't know why but my story does not read like most of these others, but it is true. She was twenty, with a noticeably larger than average size of knockers and a well-rounded butt to fill out the package. I guess she was a little of an exhibitionist and that kind of makes me a voyeur. It started probably when I was 15 and she was 18, she would hang out around the house in a cotton nightshirt that went down to her knees. And I would stalk around for a good shot when she would sit in a chair and bring her feet up spread wide and make a tent with her knees and the nightshirt. My god her cunt in this position was mesmerizing to me. It was a soft reddish pink mound with a thin slit.

I was 17, and had my first summer job. My mom and my younger brothers and sisters went to the beach for 2 weeks at the end of July. My mom said I could stay home to work my job. I really needed the money because I was going to college in the fall.

I guess I should say this now. I know that my sister was bisexual at this time in her life. I think that when she tried to pull this off, she was trying to get me to eat her out and figured that maybe she would have to give me a blow job. The sequence of events did not turn out that way. About a week before my mom left my sister and I were alone in the kitchen and she mentioned that this guy didn't like her taste and did not want to eat her. Now was she talking about her cooking, which, personally I would not eat either or did she say "he would not eat me". Well I can tell you my mind was racing when I responded, "well I am sure he is missing out on something real fine". She said, "that's what I think" and got up and left the room.

Well my mom and little sister and brother left Saturday afternoon and I really did not see Sandra that weekend, but I did remind her I could use a ride to work on Monday morning. It was about 6:45 AM Monday when I got the newspaper and was sitting at the kitchen table having some cereal when my sister came down the stairs. I was a little surprised she was up and about that early. She came over and picked up part of the paper and sat down putting her feet up on the chair and making that all too familiar tent with her nightshirt. She was just far enough away that I could not get a straight shot to her mound, so I had to conspicuously lean in that direction. I figured that it was pretty safe, heck she had the paper up in front of her face. I think she got a glimpse of me scopin' her so she ruffled the paper to give me a warning and she put it down and went to the 1st floor bathroom down the hall from the kitchen.

When she came out of the bathroom and turned towards the kitchen I could not believe my eyes. Here was my sister walking right towards me with her nightshirt unbuttoned up to her navel. I froze, my eyes were locked on the light blond patch of beaver fur walking straight for me. Well, she turned when she got in the kitchen and got a glass and went to the fridge and got a drink. I am rushing a mile a minute thinking what's she really planning here, as I continue to fiddle with the paper. It did not take long, I can tell you that. She closed the refrigerator door and walked right up to me and asked what was so interesting in the paper. I put the paper down and turned towards her and saw her cunt right at my eye level. I said "nothing as interesting as this", as I reached out and gave her pelvic area a rub.

She goes," if I didn't know better I would say you were still hungry", and she turned away from me. All I could think to do was grab her nightshirt from the back and hold onto her. She looked back at me and said "Rob!" in an inquisitively passionate voice. I quickly asked if she would bend over. "Why, do you want to lick me?" At this point I am sure I was stammering, but some how I got out a "yes". She bent over all the way and looked up at me as I pulled her nightshirt to one side. There in front of me was her pussy, god it was close. I could not believe it, I was nervous, anxious, hell I was shaking all over as I leaned forward and lightly licked her cunt for the first time. She made a slight noise as I touched her and that had a calming effect on me and gave me some courage to go for another pass. In those first couple of minutes I licked her slow and deliberately, each time pushing my tongue deeper into her. I am telling you I really did not know what to expect or what should I do next.

She was starting to get fired up because I was starting to get a major dose of her juices in my mouth, when she straightened up and said, " this is getting interesting, come up to my room". As we started down the hall I was right behind her and I was using my tongue to explore this wild taste I had in my mouth. As I took the first stair-step I felt the raging hard on I had locked in my pants. As she got to the top of the stairs she reached over her back and grabbed her nightshirt and in one motion pulled it off, over her head. There, walking in front of me, buck-naked, was my sister and we were going to her room so I could finish eating her out. Mother Fuck so to speak. She turned and hopped on to the bed and covered her breasts with her nightshirt. I went to my knees and buried my face in her crotch as I started to tongue her all over. After about 3 minutes it seemed like everything I did made her moan with delight. By now she had pushed her nightshirt away and I could she her tits. They were white and soft and big. Even at twenty they had a certain hang to them which showed off their true weight. I just kept licking and squeezing. A little later she came. I felt a big twitch in her legs and pelvic area as she rapidly grabbed for breath and grunted out an "ahhhh!"

My face was soaked and I rubbed it on her inner thigh as she drew quite a few breaths of air. As I rose up I looked her in the face with a smile and she had this most amazing glassy eyed shit eating grin on her face. I would soon get to know that look real well. She smiled back at me and I reminded her about my ride to work. I told her I was going to get cleaned up and see her in a few minutes. I went to the downstairs bathroom whipped my dick with 3 strokes of the hand and I was blowing the biggest load I had ever shot. I cleaned up and she gave me a ride to work, I swear she was humming the whole way, what was the song, oh yea, "what do you do with a drunken sailor early in the morning".

Two days later I came home around 10:30pm after hanging out with my friends. My sister's car was there and not long after I closed the door she came down the steps in her nightshirt. I am sure I had an instant boner, hoping I would get another chance to have sex with her. Well I asked her if she wanted to blow a doobie with me and she said, "Yeah". We went to my room, which was on the first floor, and I sat at the desk and she hopped up on the bed. She was a little coy and did not pop me a view right away. After I rolled the joint and lit it, I think it was the third hit she brought her legs up and I scoped her out in a pair of panties. My first though was she was saying that she was off limits or something like that tonight. But I immediately went to my knees in front of her as I handed her the joint and slid my two hands in and started to rub the front of those panties with my thumbs, ever so lightly. She cooed and said, if I get the same treatment I got the other day I might just have to give you a blow-job as a reward.

Well that was it. I was on that pussy like a rabid dog. I don't know what I was thinking but I just started to lick her pussy right through those panties, and I just kept licking and licking pushing harder and harder with my tongue. In minutes her panties were soaked. Hell, my saliva and her cunt juice just mixed as my tongue pushed her panties into her opening pussy. She was squirming like crazy when I came up for a break and I just pulled her panties off from her waist. As I pulled them down I pushed her legs back against her chest which brought her pussy way up and exposed it for me to get a deep lick into her. I repeatedly licked as deep as I could into her and it was not long before her whole body rocked as she came. I eased off and she rolled over and worked her panties off the rest of the way and threw them off the bed.

We both relaxed for a bit as she got her composure back and she turned to me as I was rubbing her and told me it was time for my blow job. She stood me up as she sat on the edge of the bed and we undid my jeans. She was babbling about nothing much as I dropped my pants, and then there was silence. I swear you could hear a pin drop, as I was reaching for my briefs. As I dropped my briefs she slowly reached out and gasped and she said, "my God, its huge."

I new I was not small but I had never had anything to base a comparison on. I had one girl friend, and I didn't get any blow jobs and I was the only guy she had ever been with and she never said much about it being overly big so I was shocked when Sandra said that. She slowly rubbed it in her hand as she tried to figure out how she was going to handle it. At that moment I realized that she is in the same position I was on Monday when she bent over, and I was going to enjoy every moment. My dick is 8" long and 5 1/2 " in circumference and as she bent down to put it in her mouth she barley got the head in. I laid down on the bed and watched as she tried in vain to get more than just a small portion of my dick in her mouth. She did a lot of licking of my shaft and balls and a hand-job but I think she started to sense that I was not really being satisfied.

At that instant she made a decision that changed our relationship drastically. I don't think she ever planned on having intercourse with me but there she was moving to straddle my prone cock. She raised one leg up to get the clearance she would need to impale herself on my dick. As she rubbed it back and forth and started to push down on it I watched as she took ever-deeper breaths. My raging hard on was back as her warm tight snatch enveloped my dick. My god she was clamped on so tight she was rocking for all she was worth but she was not taking any more of my shaft. I soon came and I think it was a relief for Sandra to get off of me. She gave me a kiss on the cheek goodnight and went up stairs. My god the next week was pure sexual bliss.

The next morning I woke up and saw she had left her panties in my room. Hell, I picked them up and headed for the bathroom where I rubbed them against my dick. They felt unbelievable, women have the coolest underwear. It was not long before I was beating off to images of my sister when I blew a load into her panties. I figured I would hang on to these for awhile and took them back to my room. My sister was still sound asleep when it was time to go to work and I went to wake her up. There she was in her nightshirt in bed, I thought about copping a feel but I didn't, just nudged her a little to wake her up. She came downstairs with the keys to her car and still dressed in just her nightshirt. Off we went. On the way I could not help but reach over to mess with her shirt and make a move for her pussy, but she stopped me. She proceed to lightly scold me for not waking her up earlier, and that if I wanted "that" I should have gotten her up. This was the first sign of her obsession. She wanted it, she wanted it any chance she could get.

I got home at 3:40 and Sandra leaves for work at 4:30. I did not see her so I went straight to the shower because I smelled like a sweaty pig. It took about 6 minutes and when I was done I headed straight for Sandra's room in just a towel. I opened up a peek, stuck my head in and said "hi". She was standing in the room with just panties on and was in the process of strapping on her bra. I quickly asked if she had time to give me another blowjob before she left. She said something about getting ready for work but I just walked in and laid down on her bed. Well you know towels and a hard-on. I was sticking straight up as the towel fell to either side. She stopped trying to latch her bra, she was way to distracted for that. As she stared at it, she asked what I would do for her tonight after work. We were in a tit for tat now. I offered to fuck her and she said that was not good enough. This game was getting complicated.

To understand what I did next you need some background on me. When I was 11, I had an accident in which my 4 top front teeth were knocked out. I wore a partial, which I could remove. I told her I would give her a gum job. She said, "A what?". I said again, "A gum job". She said what's that? I took out my teeth, pointed to my exposed gums and told her I would get her clit between my tongue and gum and roll it around until she passed out from excitement. I saw her twitch as she realized what I offered and I quickly asked if that was acceptable. She mumbled that sounds ok and quickly got on her hands and knees and grasped my cock and put a lip lock on my dick's head as if to seal the deal from her end.

She gave me a hell of a blow-job. She was much more at ease and she slid it in and out of her mouth with less tension than yesterday evening. She brought me to climax and I blew my wad in her mouth. She was able to keep most of it inside and swallow it in some tortured gulps, but some of my cum was running down her lips. I was to find out later that night that the reason she handled me so well. She had spent the day practicing with a cucumber she got from the store. Well, as I got up to leave she told me I better be here when she gets home because she will be collecting on my end of the bargain. Little did she know what I had in store for her tonight.

I got home around 10:30 and Sandra was already there because she gets off of work around 9:45. I went to the bathroom took a pee and used a wash cloth to give my cock and butt area a good soaping. When I was done I went to the kitchen. Sandra bounded down the stairs in her nightshirt and asked me why was I late? I started messing around with her, pulling her shirt and pinching her butt telling her she would get all she wanted tonight. As she wrestled back she told me she better had. She was so worked up that even though she had only been downstairs a minute or so I could smell her pussy as if I had my face right up to it. I told her lets go to my room and took her hand and lead the way. When we got there I stripped my entire clothes off as fast as I could. Sandra followed my lead but it did not take her long to shed that shirt. She got up on the bed and laid back and spread her legs.

I took my teeth out and set them on the desk and went to work. Now, I know why they call it muff diving. I leap on to the bed and Sandra literally bounced right into my face. She was giggling and laughing as I rubbed my whole face around her crotch. My nose, forehead, chin and yes my lips just rubbed her pussy back and forth. As her lips spread her smell and juice just scented my face. I was like a machine, pure concentration. I first started to tongue her hole, shallow probes at first then a little deeper. She was squirming when I dragged my tongue from her hole to her clit. She met my movement with a pelvic thrust, which just caused me to push harder against her clit. I worked her clit a little but I soon returned to her hole. I bent her legs back and spent 5 or 6 minutes tonguing her hole, just like I did last night. She squirmed a lot and she came and I decided to take a rest. I looked up at her and she had that shit eatin grin on her face and I had not even gummed her yet. I am not even sure if I had too, but Sandra was going to be my guinea pig. I was going to gum her clit until she passed out.

I lifted her legs slightly, placed my hands under the small of her back facing down towards the mattress. I brought my shoulders forward and caught her feet under them with my arms rapped around her legs. I had her legs pretty well confined, I did not want then flailing around she might hurt me. I slowly used my tongue to work up from underneath to bring her clit out. Once it was fully exposed and my tongue controlled its position I brought my gums down and started to roll her clit back and forth across the gum line. She started to rock immediately and she tried desperately to extend her legs to release the immense pressure that was building inside her. I held her legs good and tight as I did the unimaginable. As I rolled her exposed clit I started to take long breaths in through my mouth. This cool air being drawn across her clit was too much to bear. She experienced multiple spasms and her breathing was out of control as she thrashed about gasping and moaning. Her back seemed to be permanently arched against the bed as I worked her over. Whenever these spasms came, my face was along for the ride but as soon as she settled down I would go back to work on her clit. I did this for 20 minutes non-stop. When I was done she was like a rag doll. Her body was coated in the thickest layer of sweat I had ever seen, even on guys. It was as if every muscle in her body was worked to the limit and there was nothing left. When I looked in her eyes it was like a blank stare. She could see, she just was not focusing on anything.

Now it was time for icing on the cake. I got between her legs lifted them and pinned them to her chest. I buried my dick in her cunt in one push. She took almost all of it as I fucked her as hard as I could. She started to clamp my dick with her vaginal muscles as I furiously fucked her and I new I would be coming soon. She was not even making a sound. All I heard was her rapid heavy breathing. At this point I am not even sure she was conscious of what was happening to her as she repeatedly came and I blew my wad on her chest. We collapsed on the bed and I pulled her close to me as she pulled herself into a fetal position. We fell asleep that way and woke up late the next morning together.

It was too late for me to go to work so I called in and apologized and said I would not be in today. I took a shower put on some gym shorts got the paper and had some breakfast. When I was done I went in to check on my sister she was just zoning in bed savoring the fucking she had last night. I told her I was going out for awhile to help my friend and would be back later. I got back about 4 hours later around 2:30 and found my sister on the back porch in a bikini sunbathing. I walked out and sat down next to her. She asked if I could rub her back with sun tan lotion. I started at her neck and shoulders and worked my way down. When I got to her chest I made sure that my hands amply covered her sides by her tits. I then moved down to the small of her back and made sure that my hands slid under her bottoms. I though I was done when she reminded me to do her legs. Well I made sure that I rubbed her legs good and when I was working her upper legs one hand was always in contact with her pussy. She thanked me as I walked inside to get some lunch. She came in later and told me that she had found a pair of her panties in my room this morning. I said yeh, those are the ones you left down here on Tuesday. She new I had been coming in them because they were very damp with a slimy sticky coating over most of them. She asked me about that and I came back and asked her if she had tasted them to make her own determination. I told her, she was more the welcome to make a positive ID right now. She grabbed the panties from the counter top and tossed them at me. She told me I could hold on to them, that I might need them tonight since she had plans to go out with friends.

It was Saturday morning and I was in the bathroom tickling my rod when I got the balls to go up to my sister's room and sneak in. I thought it would be great to wake her up with me buried in her to the hilt. So much for dreaming. I walked in and she turned over and I sat down on the edge of the bed next to her and started to rub her butt. I asked if she had fun last night and moved my hand around to between her legs. She parted them to let me get a full rub around her crotch and I went right in. She asked if I needed anything and I stood up and dropped my shorts and climbed into bed with her. She lifted the sheets and I got in bed behind her. I was kissing and rubbing her shoulders when she reached around and grabbed my dick, which by the way was stabbing her in the back. She stroked it as I rubbed her upper torso with my hands. I worked her over with my hands and I found that she was particularly sensitive to be touched on the inside of her arm just below her shoulder. I rubbed her tits, her stomach, her arms, between her legs, I just covered her everywhere. I was slow and soft and we didn't say anything for the longest time. It was as if she wanted me to stay their forever. I reveled in the smell of her hair as I kissed her lightly on the neck.

She reached between her legs and guides my dick into her and I made a slow stroke to get inside. She was easily taking me now, which was amazing since earlier in the week she could hardly get me inside her tight pussy. I was working her and I was amazed how much feeling there is when you fuck very slow with long strokes. She was letting my dick penetrate her all the way. I could feel the opening to her cervix with each stroke. She was so warm and she had control of her vagina muscles. She would clamp me just as I started to pull out and I felt the resistance the whole stroke. This was not at all like when I was fucking her before when she seemed to be clamping on the inbound stroke just to make sure I did not impale her. I could feel her whole body as if we were one and I felt what she felt. I new she wanted to pick up the pace so I rolled her on her back and drove it deep into her. As I kept her impaled and did not move her mouth opened and I leaned forward and kissed her. She had her eyes closed and she passionately kissed me back. I felt her vagina twitching from my continued presence so I slowly pulled from her. She followed me by lifting her ass off the bed but I just kept pulling back. Then I drove forward and pinned her to the bed. We kissed one more time and I then just started to stroke her long and deep. We both came in a tremendous bang and I emptied my load in her. It was the first time I had done that and I could feel every eruption emptying into her cunt.

I pulled out of her and she turned and grabbed my dick and started to lick it clean. Cum, pussy juice what ever was there she cleaned up. Then she started to deep throat me. I watched in disbelief as she took in as much as 6 inched into her mouth and throat. She tried her darndest to take more. I tried not to move a muscle. I just watched as first she got in 4 inches then slowly gobbled down another inch. She then slid up and down for about 6 strokes then went back to swallowing more. This time she inched down about 5 or 6 inches and I could feel my dick swelling inside her mouth and throat. She definitely was determined to get as much of me as possible because she worked me for 15 minutes. I could not hold back any more and I blew my load. She was proud of what she had done hell I was too. I gave her a kiss and went to take a shower.

That evening she got home late and she woke me by making a clatter in the kitchen. I came out in my briefs and she coyly said, "did I wake you". She was flirting and had been drinking so I walked over and started to tickle her. We wrestled around when I grabbed her and picked her up by both legs and she straddled my waist. She coyly asked if I would fuck her standing up. I told her to choose her pleasure. She reached between her legs and worked herself onto me. At first I held most of her weight but as we got into it more I started to let her take more of the load. She had two places to hold on, one was to hold around my neck with her hands and the other was to hold on to my dick with her pussy. She was soon screaming as I impaled her and she desperately clamped to my dick to stay up. She just locked down and wouldn't let go. Her eyes where bugging out with lust as she rode me. At the last second I set her down on the kitchen table pulled my dick from her and blew my wad on her belly. We went to her room and she left to go to the bathroom to insert her diaphragm. We both new I could not cum in her again like I did this morning without protection. She came back and gave me a blowjob to get me hard. She did a lot of teasing and face making as we played together. Soon we were fucking and we did it from behind, her on top, missionary. Hell I think we were fucking for two hours. I know I came in her three times. We both fell asleep in her bed.

Sunday through Tuesday we got in a rhythm and we were fucking pretty regular, at least 3 times a day. But on Wednesday she had to leave to go on a job interview out of town and would not be back until late on Thursday. Well, mom was coming home on Saturday and that left just Friday for one last fling. I think we both new we were enjoying this way too much. I can't speak for my sister, but I know I could not help it. I new Friday was it, so I wanted it to be one big orgy. I took off work and planed to spend the whole day seeing to Sandra's every sexual desire. I woke up at 6:00 and went up to Sandra's room. I cracked the door and peaked in. She was sound asleep, so I went up and started to massage her pussy with my hand. As if by instinct she pulled her leg up and gave me full access to her snatch. I buried my head and started to tongue her opening. She rolled over and I new she was coming around so I lifted her leg and stuck her with my dick. As I was slowly stroking her she softly called my name and I bent down and kissed her. She smiled as I withdrew and we cuddled together and both drifted back to sleep.

We got up around ten and took a shower together. When we were drying off she told me, "I want to do something special for you today". I asked, what she had planned and she said she was going to deep throat my whole dick. I said, "no way". But she insisted she would, she had been practicing. I told her I would be amazed, if she could. We both hopped on her bed and she started to suck me off. She had this strategy to do it and I watched her. First she would move circularly on my dick followed by pushes down the length of the shaft as she took more in. Then she would follow up with a set of long strokes the length of the shaft. Well she got to her previous best about six inch pretty quick and I can say my dick was like a rock. I had not blown a load since she left. Well except for the three or four in her panties she left me, well they don't count anyway. She seemed to be hitting her limit there but she had a surprise in store for me. As she started to push down to take more she twisted her head on my shaft like 60 degrees and my dick slid past and down her throat. I watched in amazement as she just kept working her lips and more and more of my dick disappeared. As my head slid further inside her throat I thought I might blow my load right there. She must have had almost my whole 8" inches in when she backed off. She had the biggest smile on her face when she came up for air and whispered, "I told you so". I wanted my dick down there again so I quickly said you didn't get all of it yet. She told me not to worry, she would, as she went for another dive. She held up her end when she took a deep breath immediately passed into her throat and continued to suck me down until she was at the base of my cock. As she paused I exploded inside her throat. She felt my dick expand and contract as each load was deposited in her throat. As she pulled off she choked and coughed but she proudly exclaimed, "express load to the stomach". She was right about that. That was going to be a hard act to follow. I gave her a quick doggie style fuck to cap off this session.

After my mom got home from the beach we cooled it off and soon my sister moved in with some friends. We sneaked in some zesty sessions during the thanksgiving and Christmas breaks. As summer rolled around and vacation time came up, we did the nasty in late May and June as a tune up for when the family would go back to the beach. This next summer was as good as the last maybe better. Sandra had me butt fuck her for the first time. Talk about screaming with ecstasy, she was a babbling sex fiend for two weeks after that fucking. Well we had sex pretty routinely for 4 years when we both agreed that we should taper off. Man it was one wild ride while it lasted.

--------------------------------------------------------------------------------

Two summers later my mom was heading back to the beach for a month and she asked if I would look out for my little sister Cathy and check in on her maybe even stay over while she was gone. Cathy was 19 and she was home for the summer after being away at college. She was the only one in the family to go away to college, so we had not seen much of each other since last summer. I told my mom I would, and on Saturday evening I went to my mom's to check in and use the garage to work on my car. I was going to take the heads off my car and have a valve job done. At about seven, Cathy came out and told me she was going out and would be home later. I told her I might still be here, I just did not know. She told me she hoped I would stick around even spend the night.

Well she got home around 10:30 which I though was early. She had just gone to the pub and split a couple of pitchers with four friends. She came in the garage and hung out chatting as I was finishing up. She told me to get done and come inside because she was going to make some margaritas. When I got inside she grabbed me and directed me upstairs and said get your shoes off and go up and get a shower your filthy. She was right I had been sweating like a pig and had black grease all over my arms, hands, heck even my face. Well I showered up and got on a pair of gym shorts and a tee shirt and headed downstairs, I was pretty beat and we knocked off a few margaritas and I was feeling pretty loose when we needed another batch made. Cathy got up and headed for the kitchen. She was soon calling me in to help her.

"Robert get in here and help me make this batch." I got up and headed in to the kitchen and asked her what she wanted me to do. "Get the mix she said." As I turned to go to the freezer it dawned on me that she only had a tee shirt on. I was looking at a lot of bare leg that went up under that tee shirt. As I opened the freezer door she headed to the fridge to get the ice. My mom's fridge has two doors an upper and lower. As Cathy opened the upper door to grab the ice I looked back and as she raised her arms the tee shirt raised and gave me a shot at her puss. Man it was bald almost with just a wisp of hair. As she closed the door and headed back to the counter I retrieved the mix and headed over. I took the cold can and placed it on the back of her legs and she jumped and turned and told me to stop messing around. Her face was a flush crimson and her eyes were darting about as I checked her over. I saw her nipples straining through her bra and tee shirt and could tell she was fired up. We had a few awkward moments as she and I reached around each other for spoons and the can opener and the blender. She finally told me to get out after we started the blender and that she would bring out the drinks to the screen porch were we were hanging out.

We had the lights off outside and the overhead fan on and I was sitting on a outdoor couch type porch furniture. This gave me a great view of Cathy as she walked from the kitchen to the glass door. Man I am sure she knew it but when she rounded the corner with the drinks in her hand and her arms raised to hold them up I was staring straight at the finest pussy I had ever seen. She walked right up to me and stepped in front of me with her back to me to sit next to me. I put my hand out and stopped her as she passed and I had a bare butt right at my nose and I got my first whiff of her excitement. As she spoke I slid my hands up her legs to firmly grasp her ass checks and spread them. I planted my nose between her cheeks and inhaled her stank. One of the first things she said was "Oh my god" as she bent over to place the drinks on the table in front of the couch. When she did I stuck my tongue between her lips and started to work her over. Almost right away I rolled her over on to the couch and I knelt in front and just started to lick her up and down and side ways. She never tasted better, it was like virgin pussy almost. Soon she was making too much noise and I said we better go inside and close the door. We went inside and headed for the rec room. She flopped on the couch and I resumed eating her out. I soon had my teeth out and was giving her the ride of her young life. She was screaming and bucking as she came over and over again. She finally had to ask me to stop to give her a chance to catch her breath, I knew it was time to show her my stuff. As I stood up and dropped my pants and took off my tee shirt her eyes nearly popped out of their sockets as my dick flopped out.

You see my older sister was 5 foot 6 and 130 pounds but my little sister was just that, 5 feet tall and weighed 96 pounds. The shaft was like a baseball bat to her and she took a big gulp as she reached out to grab it. I quickly went for her pussy and pulled her legs out from under her and bent them back as I prepared to enter her. She just took a big breath as I inched my head in. She was tight and her instinct was not to let my dick in but I slowly worked her and got a little in and came on her chest. That night I asked her why she wanted to do that and she told me when she was 14 she saw me eating out Sandra late at night near thanksgiving and she always wanted to do that with me too.

The next day I took advantage of my superior age as a sibling and directed my sister that she need to practice giving blow-jobs and she could practice with me anytime she wanted. To my surprise she actually wanted lessons. Just like her older sister she wanted to mount my pole and fuck it till she could not take any more. Man what a summer this was going to be. By the forth day we had worked up to fucking three times a day and a blow-jobs for practice. That night after a simply torrid fuck where she really started taking me to the hilt and I was tagging her cervix every thrust did we collapse in bed together and just spend the night in the same bed. Soon we were spending every night in the same bed fucking before we went to sleep. She was like a rabid dog in heat. We did it in the bedroom, in the kitchen, on the porch in the bathroom hell maybe every room in the house. We did it lying down, missionary, doggy style over the arm of the couch on the kitchen table on the floor standing up on the stairs, sitting in a chair.

By the time my mom's vacation was over I was entranced. Cathy was going to be heading back to school and I would not be seeing her till thanksgiving. For the next six years through college and graduate school she always made time for me a couple of days a month to fuck our brains out. Heck even when she had a boyfriend she still would call up and setup some time for us to be together. We have tried to taper off but I think it is going to be hard. My mom just suggested we rent a place together and Cathy agrees.
