None of the events actually happened. If you are under the age of 18 you should not be reading this. Teaching Elliot and Sara At The Lake House Hi my name is Jake and this is my story of what happened last summer at a lake house. I am now 14, dark curly hair that covers my ears, I have brown eyes, straight teeth (after almost two years of braces) and I have a boner most all day, and probably all night. My dick is not as big as other boys my age, but last time I measured it from base to the tip, it was 4 3/4 inches hard. I am circumcised and jack off about 3 or 4 times a day. I have fooled around with some other boys, you know, like jacking off, sucking each other some kissing, but when we did it we always said it was just so we knew more about sex, and then when we got girlfriends, we wouldn't look stupid. Not that I believed that, I just did it because it was fun, and I liked how boys dicks felt in my hand and mouth, but that is something I have never told them. I have a younger sister who is 12, and is kind of a tomboy. She is always out playing baseball or basketball with me and my friends. She loves wearing a baseball cap most everywhere, and it really hides her pretty long brown hair. She also has brown eyes and cute freckles that cover her nose and cheeks. She is lucky, because her teeth are perfect and she doesn't have to wear braces. She is about 5'2 and skinny, I think she told our mom that she weighed 85 lbs. That is compared to my 5'8 and 130 lbs, so I guess being short and skinny is a family thing. At school I have heard other boys talk about Sara, saying she was a "future fox" and they couldn't wait to see her all grown up with boobs. Up until last summer she never even wore a training bra, but that changed when she decided she was going to be less of a tomboy and more of a girl. I think I liked it better when she was a tomboy, but I have to admit that she is more fun in other ways now that she has started acting like a girl. That is what this story is all about. Last June, my dad got an invitation to use a company lake house for two weeks, as a reward for all his hard work and overtime. So right after the 4th of July we packed up our van and headed to the lake house. When we got there both Sara and I looked at each other and gave a high five. The house was awesome, and big, and had like everything a kid could want. There was a big slide that went into a lake, along with a tree swing so we could hurl ourselves into the lake. There was also a large hot tub and even a small sailboat tied to the dock. The house was huge, with three big bedrooms downstairs, and 4 upstairs. There was a large game room with a pool table, and a big plasma TV. It was just plain awesome. We could see the pride in dad's eyes and face as he watched us run around ewwing and awwwing about most everything, I could tell that he finally felt all his hard work was worth it, by just seeing the looks on our faces. Him and mom just kept hugging and giving each other little kisses as we ran around, and I am pretty sure there were some tears of happiness in both of their eyes. Then dad gave us the mandatory dad talk, about how all of this belonged to someone else, and we needed to be careful and not break or abuse anything at the house. "Now you two can go to the van and bring in the luggage, and after that you can get into your swimming suits and check out the lake." He said. We both raced each other out the door and to the van to retrieve our stuff. Within 20 minutes we had both brought in the luggage, taking mom and dads to a big room down stairs, and then taking our stuff upstairs. I picked my room first, and Sara picked the one right next to it, because there was a big bathroom with huge whirlpool bathtub in it that was shared by both rooms. We closed our doors and changed into our swimming suits as fast as we could. And I raced down the stairs making sure I beat her out the door. She was about 2 minutes behind me, when she came running out the door and I noticed that she was wearing her two piece bikini that was like a neon green. Her bikini bottoms barely covered her cute ass. Yes, I said cute ass! Maybe from listening to all the guys talk at school, and the one night when I was sucking off one of my 12 yr old buddies, he was holding the top of my head and telling me that I looked so much like Sara, and he wished it was her sucking him off, that had me looking at my sister as more then just a sister, and more like a sexual person like everyone else our age . Both of us had spent the last month running around outside and getting a pretty good tan. From looking at her I could tell she had spent a lot of time sunbathing in that suit, because even the part of her ass that was showing, was really tanned. My dad even mentioned that he was going to have to lock her up so no guys could get to her, when he saw her come out the door. Sara just blushed and put her baseball cap on and we started walking down to the dock. Dad made sure that we knew how far out we could swim, and not to go outside the ropes that marked the swimming area of the lake. He reminded us that the swimming area was being shared by three other houses, and if some people came out to join us that we needed to be respectful and not make a lot of noise and splash round because they may not like it. Then he told us that him and mom were going to go into town to do some shopping and would be back in a couple of hours. He knew that we would be safe, because we had both taken swimming lessons and I had gotten my Jr. Red Cross badge for lifesaving during a winter course at my middle school. So after he left Sara and I spent time jumping off the dock, and sliding down the big slide into the cool lake. I was the first one to use the rope and throw myself into the lake, Sara thought it looked scary and wouldn't do it. I had flung myself off the rope 3 times and would come up out of the water to see Sara looking down at me to see if I had drowned, and then after the 4th time I popped my head up out of the water and saw that she wasn't looking at me, but was staring towards the beach and taking her hat off trying to comb her hair with her fingers. She had a funny look on her face that I had never seen on her before. I looked over in the direction she was staring and I knew instantly what she was acting funny about. I saw about 20 yards away from the dock a boy was walking towards us, all alone in a pair of Speedo's. As he walked closer I could tell that he was younger then me and closer to Sara in age, his whole body was lean and tanned, at first I thought he might even be Spanish. His hair was black, and it looked like he had used gel to spike it up. The whole time he walked to the dock, neither Sara or I spoke or took our eyes off him. Even in the cool water I could feel my dick stiffen as I examined the tight fitting Speedo, and saw the small bulge his squished dick and balls were making. Just before he stepped onto the dock he waved at Sara and then to me as I stood in about 4 foot of water. "Hi, you guys mind if I swim with you?" He asked in his beautiful voice. Sara got wide eyed and tried talking but it was me who answered him first. "No, we don't mind, we were kind of hoping there would be other kids here." I said as I started wading towards the dock. "Yeah, me too, it sucks being out here by yourself, I was here all day yesterday and no one came out to swim, but I looked out the window and saw you guys, and really got excited. My name is Elliot." He said as he stared at Sara the whole time he talked, and then he put his hand out to shake her hand. Sara put her hand forward and shook his hand and blushed before replying. "Hi, I am Sara, and that's my brother Jake." she said while pointing out to me with her free hand, but not letting go of Elliot's hand. I was getting up on the dock and reached out my hand to shake his, and he looked down to see that Sara still had a hold of his hand. "Sis, you can let go of his hand now." I said. She suddenly realized what she had done, and quickly released it letting Elliot shake mine. I was glad that I had on my board suit, or he would have noticed my boner right away. To put it in simple English, he was hot!!! For the first time I saw Sara looking at a guy, the way I knew I looked at guys. Then she suddenly turned around and walked over to the edge of the dock and took a dive into the lake. "How old are you Jack?" Elliot asked me. "I will be 14 in September, and my name is Jake." I replied. "Oh, sorry I thought she said Jack, but I wasn't listening real well. I know you don't want to hear this, but your sister is super cute." He said. "Yeah, Yeah, I hear that a lot." I said laughing. Then we both watched as she swam around by herself for a while. "How old is she?" He asked me. "She just turned 12." I answered. "Hey, I just turned 12 too." he said. "Then maybe you two should get married." I said with a giggle. "Eww, yuck, I don't want to marry her." He said. "Why not, you're really cute, and so is she." I said. He looked at me for a second and I realized I had called him cute. "Because I want to fool around with lots of people before I get married." He said. "Oh, so you get lots of sex now?" I asked sarcastically. Elliot blushed and then punched me in the arm. "I will race you to the swing." He said changing the subject and running off the dock and towards the tree swing. As he ran I told him he could do it, I was tired and wanted to rest on the dock. "Chicken!!" He yelled as he kept running. Sara got out of the lake and walked up to me. "What were you two talking about when you were looking at me?" She asked curiously. "I think he wants to have sex with you." I blurted out before laughing. "That's not funny!" She said as she hit me in the chest. I could see a curious smile on her face as she hit me, and the thought ran through my mind, that my little sister, the tomboy, was blushing because Elliot had stirred up her sexual side. We both watched as Elliot got on the swing and flung his cute body out into the pool. "He really is cute, ain't he?" Sara whispered to me. "Yeah, he is really cute." I said without thinking about it. "So it is you who wants to have sex with him." She said giggling. I turned and stared at my little sister wide eyed and blushing. "Why would I want to have sex with a guy?" I asked. "Hey Jake, I am your sister remember, I hang out with you and your friends all the time, I know what you do with Craig and Scott." She said in almost a blackmailing way. I was shocked, and speechless. "How do you know what we do?" I asked. About that time Elliot started climbing the stairs to the dock so she just looked at me and said she would tell me later. Even though I was curious as hell about what Sara knew about me and my friends, I was more curious to watch as Elliot got out of the water and walked towards us on the dock. Like I said, he was dark tanned, and now his black hair was wet and lay flat across his head, slicked back. He was probably about 5'4 and oh my god, his wet Speedo became a little more transparent as I could make out the outline of his boy dick, as water dripped from his crotch. I wanted so bad to lean down and lick off those drops before they escaped what had to be paradise. Sara also stared. "Wow, you guys like to stare at people a lot." He said noticing our stares. Then my little sister broke out of her trance, and became her old smart assed wisecrack that I had grown up with. "Well if you don't want people to stare at you, you shouldn't wear those Speedo's so we can see everything." She said. I was sure she had just blown it, and that now he was going to get pissed and walk away, and I would never get to see him in his Speedo again, but I was surprised. "So what, you are wearing a little suit too, is that because you wanted boys to stare at your hot body?" He replied. "Well... ummm... I guess.... that's not fair." She said, knowing he had trumped her. "Hey, I am not complaining, I really like your bikini." He said almost apologizing. maybe afraid of the same thing I was earlier, she might go change. "Well, you look kind of hot in those Speedo's too." She said looking at him starry eyed. "Good, so we are still friends?" He asked her. "Yeah, we can be friends." Sara said with a blush. Then after a few seconds of silence Sara dove in the lake again and Elliot quickly followed. I just lay out on the deck and watched them. Watching the two of them splashing around was really cute, and even though the boy had given me a boner, I decided not to interfere with him and Sara, after all, he was clearly a girl chaser, and did not seem to take any notice in me. Then my parents came back to the house and walked out to the dock. I wondered if Elliot would get out of the lake while they were there, but he was pretty smart, and just waded around the deeper end of the lake and chatted with me, and my parents, after I introduced them to him. They announced that they had bought some fried chicken and biscuits and we needed to hurry up and get out before the food got cold. Elliot looked disappointed, Sara looked just as disappointed, and when she got out and wrapped a towel around her she asked my mom if it was alright to invite Elliot to eat with us. "Hey Elliot, you want to go ask your parents if you can eat with us?" My mom yelled back to him as we walked towards the house. "Yeah, I would like that." He said. Then mom yelled out to him one more time. "Well the kids have to take a quick shower and change, so you can come over in about 15 minutes." He just nodded his head and waved to us. When mom and dad were in the house, both Sara and I looked out to see him dashing across the beach in his Speedo and towards his house. "He is so cute." She whispered to me, looking around to make sure neither mom nor dad heard her. "I know." I said with a wink. "You kids go take a shower and change into some shorts and shirts." Dad said. We both ran up the stairs and into our rooms. I got into the bathroom and stripped naked and turned on the shower making sure the water was warm enough. I looked into the mirror to see my naked body ( I don't know why, it is just something I always do.) when the other door opened and in walked Sara, naked, and looking at me in shock. "Sorry, I didn't know you were already in here." She said, as I saw her eyes go immediately to my dangling 2 inch limp dick, and the beginnings of a nice patch of pubes. I in return looked at her smooth tanned body, and then saw where she had no tan, her flat chest and hairless crotch. I tried acting like it was no big deal, "Well it's not like we haven't taken a shower together before, so no big deal." I said. "Yeah, but that was when we were little, and your bigger now." She said as she continued to stare at my crotch. "Yeah, I guess it is a little bigger." I said. "Yeah, it looks a lot different. But it is still nice." She said. "You look really nice too." I said. "Thanks, you think we are in trouble now?" She asked me. "Why?" I asked. "If mom and dad find out we are seeing each other naked." She asked. "Well they won't know unless you tell them, cuz I ain't saying anything to them." I said. "Good, then can I ask you if I can take a shower with you?" She asked sheepishly. "If you want to, it's no big deal to me." I said. still trying to act cool about the whole thing. After I said that, she opened the door to the shower and stepped in, holding it open for me, so I followed her in. We were both pretty nervous as we took the shower together, making sure neither of us touched the other, and carefully moving around so that the other could wash and rinse off, but you can be sure that each both of us watched and admired each others naked body. So after 10 minutes, we both stepped out of the shower and dried off. "Thanks for letting me shower with you." Sara said as she opened the door to her room and closed it behind her. It was then that I remembered what she had said at the lake, she knew what me and my friends did, my little sister knew about sex stuff we did, but how? I popped one of my teen boners just thinking about it. I went into my room and dropped the towel from my waist. "Wow, you two are really slow." I heard Elliot say, I looked up and he was stretched out on my bed lying on his back with his head propped up on my pillows. "Elliot, I didn't know you were in here." I said in shock. "It looks like you weren't expecting me, with that boner and all." He said with a giggle. I quickly turned and covered myself. "Sorry, I get that way sometimes." I said blushing. "I would have a boner too if I took a shower with Sara." He said. "How do you know we took a shower together?" I asked. "I opened the door and saw you both in the shower, but you weren't doing anything." He said. "Well no, she is my sister, why would we?" I asked. "I don't know. Just forget it, I am hungry, and have been waiting for 5 minutes here." He said getting up off the bed. I reached down and grabbed the towel and was going to put it around my waist before changing. "Hey dude, you don't need to do that. I already saw you and its no big deal. Plus you are almost as hot as your sister." He said with a wink. I blushed at him saying that, and am certain my cock jumped a little at hearing those words from his cute mouth. It took me 2 minutes to get dressed in my running shorts, and t-shirt, and then Elliot followed me down to the kitchen where Sara was already sitting with mom and dad at the table. She had put on halter top that clung to her flat chest and some blue running shorts. We all sat at the table and my parents questioned Elliot about what his parents did, and how long he had been coming to the lake. He told them that his dad owned a import company and they spent every summer and holidays at the lake. His mother had died when he was 4 and he didn't remember much about her, but his dad had hired a nanny, and she watched him most the time, since his dad traveled a lot. "So is your dad at the lake house now?" My mom asked. "Yeah, he came here with us, but is leaving tomorrow night and will be gone for a week." he answered. "Oh, how sad, do you miss him when he is gone?" My mom asked in a motherly way that embarrassed the hell out of me. "Yeah, but I am use to it, and he really treats me good when he is home, he really is not a bad dad." Elliot said. My mom looked up at my father with a look like she didn't believe a word Elliot had said about his dad being good. "Well Elliot, if you want to, you can ask your dad if you can stay with us while he is gone. Jake and Sara would love having you stay here." She said. Ok, now I think my mom is cool again, forget that she embarrassed me, now she should get the mother of the year award. I looked over at Sara and saw her wiggle in her seat hoping that Elliot would agree. "That would really be nice of you, I can ask him tonight when I get home, and tell you tomorrow." He said. Sara looked a little disappointed, but then Elliot said he was sure his dad would say yes, but he just wanted to make sure. When we got done eating and us kids went to the game room and tried playing a game of pool. I played Elliot first, and found out that he was much better at pool then me, and he beat me pretty easily. It was decided that Sara would play the winner, so she got up and grabbed a pool stick after he won. "You don't even know how to play pool." I said to her as she pranced up to the table. "So, how hard can it be?" she said. I heard the tom boy come out of her again, It took her a few attempts before she got the hang of it, but actually she got to be pretty good. I noticed that Elliot was very patient and was probably missing some shots so that he could play against her longer. It was down to just one ball apiece and then the eight ball, Sara got up to the table and amazingly made both her ball and the eight ball and won. "See Jake, I am better then you." She said as she wiggled her cute ass at me. So I got up to the table and prepared to beat her at the next game. What I didn't expect was that Elliot was going to be helping her. For some reason, she forgot how to hold the stick, and he had to get behind her and show her how to hold it properly, his body pressed against my little sisters back side as he showed her, he looked up at me and winked, so I knew for sure he was enjoying the lessons. Then I looked at her and gave her my brotherly stare, to let her know that I knew what she was doing, and she just grinned at me and winked, just like he had. I was watching two twelve year old kids getting sexy with each other. The only reward I got out of the whole thing was at one point while Sara was taking a shot, Elliot walked in front of me and I could see that he was sporting a boner in his shorts, not a huge boner, but still, I could tell he was hard. That made me hard in my shorts, so when I got up to take my next shot I tried covering myself a little, and thought I had concealed it from both of them. We played for about 3 hours off and on, before dad came into the room and said that Elliot's nanny was at the door, and wondered if he was ready to come home yet. We followed him to the door and waved as he walked home with the nanny, who was actually a pretty cute Spanish girl, who looked like she was a college student. We walked back into the game room and tried playing another game of pool, but it wasn't as fun with Elliot being gone, so we just sat down and talked. Mom came in and told us that they were going to bed, and that we needed to be quiet, and not stay up too late. We then turned on the TV and I used the on screen guide listings to see what was showing. One title caught both our attention, it was a movie called Blue Lagoon and it said it was about to kids who are shipwrecked on an Island and learned to survive until they were rescued. It was showing on HBO and I wasn't sure if we could get it, but lucky for us, we were able to see it. We turned it to that channel just in time to see two little kids, like 5 yrs old running around naked, one was a boy and the other was a girl. Sara was closing her eyes every time they showed the boy naked swimming, but I kept my eyes glued to it. Then it showed them growing older, until they were like the same age as I was. They even showed the guy swimming naked and you could see his dick dangle as he swam. I got a boner, and Sara stopped covering her eyes, and was wiggling on the couch beside me. The girl was shown naked, and I noticed her naked body reminded me a lot of Sara, flat, but actually very sexy. Somewhere in the movie they showed the boy getting frustrated and going out to some rocks and I could tell that they were showing him jacking off in private. Sara had no idea what was happening and she asked me. "He is jacking off, you know what that is?" I asked. "Oh, yeah, I think I know about that." She said and then got quiet again. Then the girl in the movie tells him that she knows what he was doing, and she saw the stuff shoot out of his thingy. He gets mad and throws a rock at her, and almost kills her. Sara turned to me and gave me big grin. "I know you squirt stuff out of your thingy too." She said. "Yeah, I do, but how do you know?" I asked. "Are you going to throw a rock at me if I tell you?" She asked. "No, you know I wouldn't do that." I said. "Well I know that you and Craig were doing some stuff with each other the last time he stayed over, I looked in the key hole and watched Craig sucking on your thingy, and then you grunted and he got up real quick and said you had shot something in his mouth. That was the white stuff, right?" She asked. I guess I should have been mad, but to tell the truth I thought it was kind of sexy that she had seen Craig sucking me off. "Yeah, that's what happened. He doesn't like me to shoot cum in his mouth." I said with a big grin. "Then why did you do it?" She asked. "Because it feels better when you can cum in someone's mouth." I answered. Then she giggled again and said that she had also watched me suck Craig and that she thought he shot stuff in my mouth because he groaned really loud. "Well he didn't shoot any stuff in my mouth, because he can't shoot stuff yet, he is too young." I answered. "What do you mean, not all boys can shoot?" She asked. "No, he is just turning 12, and sometimes it takes until your 13 or something." I said, not knowing what age guys started shooting, its just that I had my first wet cum at age 13. "So you don't think Elliot is able to shoot stuff?" she asked. "I doubt it, but he might." I said. "You want to suck his thingy and find out?" She asked me. "Maybe, do you?" I asked back. "Maybe" she smiled. I thought I was going to pass out, her my sister and I were talking about blowjobs, and up until today, I didn't even think she knew anything about sex, or had those feelings. "Have you ever sucked on a boys dick?" I asked her. "No, I just heard about it from some girls, and then I saw you guys, that is all." She said. "You ever did any sex things?" I asked knowing the answer. "Well me and Tanya have put our fingers in our slits, and we licked each other once." She blushed. I was totally shocked to hear her say this but acted like it was nothing new. "How did you learn about doing that stuff?" I asked. "She read about it, and we decided to see what it felt like, and it really felt good." She grinned. I can't tell you what the rest of the movie was about, because I suddenly had an urgent need to go jack off from everything I was hearing and talking about. "Well, I am going to go take a shower now and go to bed." I said to Sara. "Can I take one with you again?" She asked. "Umm, well yeah, but to tell you the truth I was going to jack off in the shower, so you might not want to." I said in all honesty. "I want to see that, please let me." She pleaded. "Ok, first go make sure mom and dad are asleep and then we can as long as they are asleep." I said. She hugged my neck and got up off the couch and ran to the room my parents were at, and then ran back. "They are asleep, so lets go, hurry." She said as she took my hand and helped me up. She didn't let go of my hand the whole time, practically pulling my arm out of its socket. Even though I really, really, really, like boys better, for some reason I had a raging boner just thinking of my sister watching me jack off in the shower. As soon as we got into my room she shut the door behind us and we headed for the bathroom. "Ok, take off your clothes." I said to her, and she quickly took off her halter top and then shucked her shorts and panties until she was stark naked in front of me again. "Now you... wait... Let me take off your shorts." She said as I was taking off my shirt. Then she took hold of the waist band of my shorts and pulled them down so that I was just in my boxer briefs. I could see her stare at the big bulge my almost 5 inch cock was making, and she reached up and softly ran her hand over the bulge. "You already have a stiffy." She said looking up into my eyes, then she pulled my shorts down, causing my cock to spring out and point right at her face as she kneeled down to pull them to the floor. "Wow, that looks a lot bigger then it did when I saw Craig suck it." She said. "Well you were looking through a key hole, and across the room." I said. "It really looks nice." She said while staring at it. "You really look nice too." I said as I suddenly noticed that her flat chest was looking a little puffier, and her nipples were standing out and really hard. I had heard that women got that way when they were horny, but this was the first time I ever saw it. I took my eyes off her and turned to the shower and opened the door and set the temp so that we would both be comfortable. She then took my hand and led me into the shower again, and closed the door. "Hey Jake, can you show me how you jack off your thingy?" She asked. "Yeah, but can you call it a cock, instead of my thingy?" I asked. "Ok, I want to see you jack off your cock." She giggled, and I noticed that she had one hand down and was rubbing her bald pussy. "Are you going to rub your pussy while I do it?" I asked. "Yeah, but I really want you to rub it for me." She said. Ok, now I had some decisions to make, after all, this was my sister, and it was not right. "If you rub my pussy, I will suck your cock." She said reaching out and taking hold of my cock for the first time. There is something about a hand around my cock that makes me stop thinking, and just reacting. "Ok, but you don't know how, do you?" I asked. "Well I saw Craig do it to you, and you doing it to him, it doesn't look that hard." She said, and then blushed. "Well, your cock looks hard, but sucking it doesn't." She said. "Why do you want to suck my cock?" I asked. "I know that guys like it, and I want to learn, so I can make them happy." She answered. "You want to suck Elliot, don't you?" I said. "Yeah, about as much as you want to." She smiled. "Then you want to suck him a lot." I said. The water was falling down on the both of us, and we hadn't moved much, and her hand was still wrapped around my cock, so I reached down and helped her move her hand back and forth on my boner, she said it felt so silky and soft. Once she got to jacking me, I reached down and for the first time in my life, my fingers touched a pussy, I ran my middle finger over the slit a couple times, because I had read about it on a porn site. She moaned as my finger rubbed deeper into her slit and her hand stopped jacking my cock as she took in the moment. Now I really decided to take the plunge into the heterosexual world and I took her hand off my cock and sat down in the shower and pulled her bald pussy towards my mouth and started running my tongue up and down her slit. Soon she was pushing her pelvis harder into my face, just like some of my friends had done when they wanted me to suck them deeper and faster, so I slipped my tongue deeper into her slit and actually enjoyed the taste that was falling on my tongue. "Oh Jake, that feels better then when Tanya did it, oh my pussy really feels good." She said. Then after a couple minutes her body shuttered and she gasped. I had given my little sister an orgasm, and I found out later it was her second one ever. I thought that women got all tired and grumpy after they had an orgasm, but Sara just seemed to get hornier. "Ok Jake, now I really owe you. Can I suck your cock now?" She said. I stood up and noticed that I had lost most of my erection while licking her out, but it didn't seem to bother her, because she was on her knees and licking my cock head, and then the shaft and stroked me until I was hard, then I looked down to see her mouth open as she took my cock into her mouth. Then she quickly took it out and stared at it a second before looking up and smiling at me and taking it back into her mouth. I had to give her a little instruction on what guys really like, and she caught on very quickly, and while watching her, I could tell she was enjoying it. "Ok sis, I am about ready to shoot, you better stop and just jack me off." I moaned as my hands held the side of her cute face. But instead of stopping she just held on to my ass cheeks and started bobbing faster until it was too late, and I fired all my cum into her mouth. Then she let my cock slip from her lips and I could see cum dripping from her mouth, as she tried swallowing some of it. She looked very sexy with cum on her lips, and then she swallowed hard and then licked her lips as she stood up. "Sara, you did great, but you didn't have to let me shoot in your mouth." I said as I hugged her. "I know, but you said boys like it better, and it wasn't that bad." She said. The realization that I had just got done eating out my sisters pussy and she had just sucked all the cum out of my cock hit me with a wave of guilt a few minutes after we had dried off and she followed me to my bed with just a towel wrapped around her cute body. "Sara, I am really sorry, I can't believe I just did all of that to you." I said as I held the towel around my body. "I am not sorry, I wanted to do it, and so did you, so you shouldn't be sorry either." She said. "What do you mean, I am your brother, and I think I am gay, but still I just did sex things with you, there is something wrong with me." I said. "Did it feel good to you, because it felt good to me?" She asked. "Oh god sis, it felt great, and I even liked licking you down there." I said blushing. "Jake, you are mad because you liked doing it to me?" She asked. I had to think about that for a while, because I had never found any girl sexy, just guys, but I had found Sara sexy, maybe I was mad because she showed me I could be with girls too. "I don't know, I just know that should have taken a shower alone." I said. "Jake, you know that I really like Elliot, and he is the first guy I ever had sexy thoughts about besides you, And all you did was help teach me what he would like if we ever get to be alone together. So I wanted it more then you could imagine." She said. I thought over what she had said, and I guess her reasoning justified everything we had done, and I should not feel guilty. Then I thought over what she said one more time. "What do you mean by saying Elliot is the first guy you had sexy thoughts about besides me? You had sexy thoughts about me?" I asked. "Yeah, I had sexy thoughts of you ever since I saw you getting sucked, and then you sucking Craig. I thought you looked so sexy sucking his thingy" I mean cock, and wished I could do all those things with you, and some of your friends." She said with a blush. "Sara, you are really the best sister I could ever ask for." I said. "I would rate me as a 6 as a sister, and you as a 9 as a brother." She said with a sly smile and wink. It took me a second to figure out why she was rating us like that. "Oh, so together we are a 69?" I asked. "Yeah, you know what that is?" She asked. "Yeah, it's a sex position I do with Craig and sometimes Scott. How do you know about it?" I asked. "Duh, that's what Tanya and I ended up doing, she read about it and we did it." She answered. "Did she make you orgasm like I did to you?" I asked. "Yeah, she did, but I think it was better with you." She smiled and then dropped the towel. "So are you saying we should do it before we go to bed?" I asked. She didn't reply, she just pushed me back on the bed and unwrapped my towel and got us into the 69 position. Within 15 minutes she had another powerful orgasm, and I shot a lesser load of cum into her mouth, and this time she swallowed it all. I carried her to her bed and helped her slip into her long night shirt, without putting any panties on her, and then I went to my bed and fell asleep faster then I ever remember. To be continued. Elliot learns some things from me next.
