We had done the first three miles way faster than the guidebook had suggested for planning purposes. Sure, much of that speed came from me being a horny teen enticed by his sister -(TM)s curves. Whatever the reason, we had powered our way up the trail. Even doing a mile in 25 minutes was quite an accomplishment considering that the guidebook suggested that the one way time was between three and four hours. Tanya noticed something I didn -(TM)t and started jogging down the trail. I took a deep breath and sped up to match her pace. I don -(TM)t know why she stopped, but she didn -(TM)t jog long. Almost as soon as she stopped, she lifted up her shirt and giggled as I broke into a full sprint to close the distance between us. Tanya -(TM)s tits were so enticing that I didn -(TM)t care why she seemed to be acting so strangely. When I reached her I slowed down and moved in close to my topless sister. Not even looking her in the face, I took one tit in each hand then kissed one of her nipples. I planted a slightly more intense kiss on the other one. Even though I had stopped running my breathing was faster than ever and it felt like my heart rate was increasing instead of slowing down. Groaning, I kept alternating kisses on each of my sisters nipples. Soon, I was slurping more and more of her tits into my mouth as I did so. I -(TM)m not quite sure how many times I went back and forth before I settled on one of Tanya -(TM)s big tits to nuzzle on repeatedly. As I did so, I felt her hands behind my head urging me to suck even more of that marvelous jug into my mouth. I had never been happier or hornier in my life. When I finally opened my eyes and came up for air, Tanya looked plenty happy herself. She was biting on her lower lip and her eyes were contentedly closed to near slits. -Why did you break into a run like that sis? Just trying to tease me? - -Did you notice people over the top of the ridge? Another switch back or two, I think we -(TM)ll be at the lookout point. If I was going to give you your reward for good behavior I needed to do it soon and find a spot that was out of view. - -I love you Tanya. - -Oh shut up, you -(TM)re just giddy from getting to second base in a major way even if it is with your sister. Suck on my other boob now; it -(TM)s feeling left out. - I gladly complied with Tanya -(TM)s request as I started filling my mouth with the tit I hadn -(TM)t spent the last five minutes sucking on. -Damn it! How can you be so good with your mouth on my nips, really anything to do with my chest, when you didn -(TM)t have a clue as how to kiss. It -(TM)s like you -(TM)re some sort of idiot savant of boobie handling. - -At least I have some sort of useful talent, - I told Tanya. -Too fucking useful. You -(TM)re going to get me in a lot of trouble big brother. Speaking of useful, git that mouth back on my boob where it belongs. I didn -(TM)t tell you that you could stop. - I couldn -(TM)t believe my ears, in a little under a mile, we had gone from setting a timer for the time I was allotted to play with Tanya -(TM)s tits to being scolded for stopping! I didn -(TM)t even make a silly remark about her wish being my command. If she wanted me sucking on her tits, I was going to suck on her tits! It was then I realize my cock was feeling really good; like about to cum really good. I tried to take a break so I didn -(TM)t have a hands free orgasm. As soon as I tried to pull away though, I felt Tanya -(TM)s hand holding me to her chest and I couldn -(TM)t help myself. I started sucking really hard causing Tanya to cry out in surprise. My mouth was full of amazing tit, and I tried to suck even more of it into my mouth as I felt my cock become absolutely rock hard before the amazing relief of jizz flowing through my shaft hit me. It seemed to pump out endlessly in the most intense orgasm I -(TM)d ever had as I sucked on one of Tanya -(TM)s tits and felt both of them up as I came. I started sucking and squeezing in time with the pulses of jizz I was shooting into my shorts. After I was done cumming, I managed to get my mouth clear of tit flesh and sighed, -Oh wow! - -You got a little excited there Mike. - -That -(TM)s because my cock was spewing cum, Sis. - -What? I didn -(TM)t even touch you below the waist, and I know exactly where your hands were, - Tanya said pushing me away from her. -You can -(TM)t have cum! - -Your tits are just that amazing! - I looked down at myself, and I had cum so damn hard there was a glob of white semen on the outside of my shorts. -Fuck, I knew I was pumping out a big load, but that -(TM)s kind of crazy. It -(TM)s going to look like I pissed my pants up at the lookout, -I said as I wiped the obvious white glob on a nearby rock. That did nothing to hide the wet spot I had created though. -Oh, just dump whatever is left in your water bottle all over you. I -(TM)m sure you can refill it at the lookout. Speaking of looking decent for the crowd up above us, I should at least put my sports bra back on. Tanya took her undersized shirt off and started rooting around in her backpack when inspiration hit me. I got the good camera back out and said, -Wait Sis, let me get some pictures before you put the sports bra on. - -Are you crazy? That -(TM)s the family camera. You can -(TM)t take topless pictures of me with that. - I snapped a photo of my sister and laughed, -Too late. - She was bent over at the waist, and I now had a photo of that with her amazing tits pointing straight down at the ground. -You are such an idiot, you -(TM)re just going to have to delete that. - -Well come look at it first, you look totally amazing Tanya. - -Fine, - Tanya huffed. -Hmm, I guess I do look pretty good. It -(TM)s not really like I check myself out in the mirror in that position. - -So let me take a few more. - Even though I had just cum really hard, I was starting to get hard again taking topless pictures of my own amazingly sexy sister. After the first few, Tanya started to enjoy herself, striking sultry poses or playing with her tits as I snapped picture after picture. Those poses had me fully erect again. -OK, that -(TM)s enough Mike. Delete those so we can take pictures at the lookout and show them to our parents when we get back to camp tonight. Maybe the time it takes to delete all those will give your cock a chance to calm down. - -Wait, I -(TM)ve got an idea, - I put the lens cap back on and pressed the button several times. -Here, we -(TM)ve got a buffer of about a dozen blank pictures. We -(TM)ll just be careful to start at the first picture of the scenery and make sure they only scroll through in one direction. -I swear Mike, if we get busted because my brother wanted to have topless pinup pictures of his sister... - -Don -(TM)t worry, this will work. You know Mom and Dad have never tried to get good at using this digital camera. Dad still thinks of it like his old film SLR and Mom couldn -(TM)t take a good picture to save her soul. - -You had better be right about this you horn dog, - Tanya grumbled as she wriggled back into her sports bra. The thing really did squash her ample rack down into near flatness. It was kind of amazing even though I was missing the sight of her freely bouncing breasts I had become used to rather quickly. Removing the sight of those braless tits also caused me to lose my hard on. -Uncomfortable ass bra, - Tanya grumbled. -Well, let -(TM)s get up to the top of this trail. - Chapter 6: Majestic View Tanya and I walked the rest of the way up the switchback to the scenic lookout. A few people noticed us coming from the steep trail and looked at us with a bit of amazement. However, after a few minutes of milling around, we were indistinguishable from everyone else checking out the amazing scenery. I switched to the wide angle lens and got some great shots that would really impress the parents. After taking some photos, I walked up to Tanya and put my arm around her waist and tried to kiss her. She hissed at me, -Mike, what are you doing? We can -(TM)t kiss here! - -Why not? No one knows who we are or that -(TM)s we -(TM)re related. We -(TM)re just some young couple to anyone watching us. - Seeing the logic of my statement, Tanya tilted her head up and I kissed her on the lips. It wasn -(TM)t the wild make-out kissing we had done on the trail, but it was more than a little peck on the lips. I was getting so turned on by kissing Tanya even though I had just cum in my pants from sucking on her tits a little while ago. Tanya stayed by my side with my arm around her as we continued to look down on the park from our elevated position. I was getting really used to being super close to Tanya for an extended period of time. The whole thing was making me giddy, like we were really boyfriend and girlfriend instead of brother and sister. As far as the people who paid us any attention, that -(TM)s what we were. I had Tanya take some pictures of me with the park in the background, and then I did the same for her. We even set the camera on a bench and got both of us in the picture at the same time. It was so hard not to try to kiss Tanya while we were posing for the automatic photo. I had to keep reminding myself that these were photos our parents would see when we got back to camp later tonight. We were able to refill our water bottles and just generally rest up after the rapid rate we had gone up the steep trail. There were even some automated machines and we picked up a snack. All and all we stayed at the top of the path for about an hour. I -(TM)d have been inclined to stay there longer if it hadn -(TM)t been for the developments with Tanya on the way up the trail. I kept starting to get hard again when I kissed Tanya in front of all the other people here. Now I was half hard just sitting here resting, and if I thought about Tanya at all my cock started to throb pleasantly. Then I started thinking about how she was likely to want to get out of her sports bra as soon as we were out of sight of the people up here and I let out a sigh and got really hard. No matter how majestic the view was up here, as a horny teen boy, it couldn -(TM)t compete with the majestic view of my sister -(TM)s chest. Tanya looked at me and then down at my crotch and stated, I had better get you out of here before you get busted for being the big perv that you are. Chapter 7: Dry Humping I think Tanya was as eager as I was to get away from the crowd so we could fool around some more. The trail was still difficult going downhill. But it wasn -(TM)t difficult in the same way that going up the trail was. The uphill hike had mostly been about cardio. Going downhill was a strain on the muscles in the legs to keep from building up too much speed. I tried to go back to making out as soon as we were out of sight from the lookout, but Tanya held herself at arms length after a few quick kisses. -Wait, I -(TM)m looking for the right spot. - -Right spot for what? - I wondered. Tanya replied, -You -(TM)ll understand when I show it to you. - We walked a few hundred more yards before my sister found what she was looking for. -There, go sit on that rock. - It was a pretty big rock, roughly two feet square by four feet. I realized I was pretty much putty in Tanya -(TM)s hands as I did what she told me without any resistance. Once I was seated, my sister moved closer to me and stood on the rock straddling my legs. -Help me sit down without busting my ass. - It was a little delicate, but with my help, Tanya managed to sit down on my lap with her legs wrapped around me. My cock and balls were tingling and my eyes were drinking up the sight of my sister. -Oh Tanya, - I moaned as I leaned forward to kiss her. She didn -(TM)t let me kiss her long, not nearly as long as I wanted to, and she teased me. -If you -(TM)re too eager to kiss me, I -(TM)ll never manage to get this shirt and bra off. - I groaned this time, but leaned back to give Tanya room to strip. Once the shirt came off, I really couldn -(TM)t see much more than i had before, but just getting to see her pull her shirt over her head was a real treat. Then she started the more difficult task of getting out of the constricting sports bra. I was in heaven as Tanya -(TM)s big titties came into view again and my mouth descended on hers with no resistance this time. I pushed my tongue into her mouth so that I could make out with my sister properly. Then I started kissing my way down her neck so that I could suck on those amazing tits. Not long after I got one of Tanya -(TM)s jugs into my mouth and as I was feeling her nipple harden under the lapping of my tongue, I felt the warmth of her pussy pressed against my swollen shaft. I gasped at the unexpectedly powerful sensation, and Tanya -(TM)s tit fell out of my mouth. -Aww, why did you stop big brother? You know I like the way you handle my big boobies. -I know, and you know I love your boobs, but now I can feel the warmth of your pussy against my hard cock. - -Mmmm, I can feel the warmth and hardness of your cock rubbing against me too. It feels really good, - Tanya purred. As she pulled her body closer to mine, the pleasure I was feeling became even more intense. Just when I didn -(TM)t think anything could be better than Tanya -(TM)s tits, she did this to me! It felt so fucking good! I -(TM)m not sure when she had come up with the idea of getting into my lap, but I was glad she had. I put my hands on the small of her back and pulled her even closer causing me to grunt with pleasure. I -(TM)d have cum right then and there if I hadn -(TM)t cum earlier from just sucking on her ripe, round tittles. Since I wasn -(TM)t that full of cum though, I was able to grind my shaft against Tanya, and I was starting to feel the indentation of her slit. Instinctively I rocked my hips back and forth and I was consumed by how good it felt. I never wanted to stop. -Oh Mike, that feels amazing! - She started rocking her hips against mine, and almost immediately we were both dry humping each other through our clothing. Tanya -(TM)s lips found mine somehow and I could feel her hard nipples rubbing against me. I managed to get out of my shirt so that now those amazing hard nubs and her soft round breasts were rubbing directly against my skin. -Mmm, I think I have too many clothes on also. - Torn between the desire to keep Tanya in my lap until I came and the desire to see her strip out of even more clothing I helped her stand up after a moment of indecision. She unsnapped her shorts as I stared at her topless body as she stood over me. I found her tits so beautiful that those were what I stared at even though she was at least taking her shorts off. Without taking my eyes off Tanya -(TM)s amazing rack, I wriggled out of my shorts as well. I sensed more than saw Tanya kick her shorts off, and as I helped her sit back down, I saw she was still wearing her panties. The difference in the sensation of dry humping my sister through our shorts and through our underwear was amazing. I didn -(TM)t want to stop before, now I simply couldn -(TM)t stop. It wouldn -(TM)t matter if every single sightseer from the top of the hill came down and saw us. I would simply keep playing with my sister -(TM)s body. -You -(TM)re making my cock feel so fucking good sis! - -You -(TM)re still trying to make this weird Mike, but I don -(TM)t seem to care. I -(TM)ve never let a boy get this far with me before, and it feels absolutely amazing. - My cock seemed to be demanding more direct access to Tanya -(TM)s pussy, so I managed to fish my rock hard shaft out of the opening in the front of my boxers before dry humping Tanya some more. -Mmm, Mike, I think you -(TM)re going too far. I should tell you to stop and put that back in your pants again, but it -(TM)s so hot! I mean like physically hot. I wasn -(TM)t expecting a cock to feel that much different than a finger, but it does even through my panties! - -I love your panties Tanya, - I said. -They -(TM)re so silky smooth over your pussy, which I can -(TM)t get enough of by the way! - Chapter 8: All the Way -Oh, I -(TM)m in fucking trouble! - Tanya moaned. -I never realized getting to third base was so much fun. I -(TM)m going to have a hard time stopping guys from going too far after this. - -Any time you feel tempted, you can just let me know and I -(TM)ll take care of your third base needs, - I teased. -Sure, that -(TM)ll work on a date. No, you can -(TM)t put your hand in my pants because I -(TM)m going to let my brother do that when I get home. - -Hey, you never know until you try, - I countered. - You -(TM)re right though. This feels better than anything I could imagine, except maybe. - -No, you -(TM)re my brother, we can -(TM)t! - -No, not sticking it in you, but you know, touching you with my hard cock without the panties in the way. Just on the outside, I swear! - -You had better not try to slip it inside me; I swear I -(TM)ll kill you Mike. - -No tricks, I swear. I just want to see what it -(TM)s like skin to skin. - -OK, - Tanya said swallowing hard as I looked down between our bodies to see her tugging on her panties. I was hoping for a clear view of my sister -(TM)s pussy, but her bush obscured it after the panties were out of the way. I tapped the head of my cock against Tanya and the urge to stuff her full of hard brotherly dick nearly overwhelmed me even though I had just said I wouldn -(TM)t do that. I scooted closer to her so that I could grind my shaft against her slit. It was even better than dry humping her through her panties. I wondered how long I could do this without cumming. I didn -(TM)t feel the urge quite yet, but I was so incredibly hard from rubbing my cock against her pussy and the feel of her tits pressed up against my chest. Then I suddenly felt something even more intensely pleasurable and I did need to cum. It hit me that my cock, at least the tip of it was inside my sister! Even worse, the need to cum was going to overwhelm me if I didn -(TM)t pull out immediately, -Not safe! - I gasped as I pushed Tanya away from me. My cock popped free, but I couldn -(TM)t stop thinking about how it had felt to be inside Tanya. Even though I had imagined that actual sex would be better than fooling around at third base, I hadn -(TM)t been prepared for how much better it was. Damn my sister -(TM)s pussy was sweet, and I had barely experienced that sweetness at the entrance of her slit and only for a second or two. I let her snuggle close to me again, but as soon as my cock came back into contact with her pussy, I wanted to have sex with Tanya more than anything in the world. Everything about her pussy just felt so good to my cock! I had to push her away again. -Mike, - Tanya pouted, -Why are you pushing me away? - -I promised I wouldn -(TM)t try to have sex with you, but if my cock touches your pussy one more time I don -(TM)t know if I can keep that promise. I -(TM)m not sure how I ended up inside you in the first place. I was trying to be careful to make sure that didn -(TM)t happen. - -I know, that was me, - Tanya explained. -The way you were rubbing on me was driving me crazy! I just had to get you inside me. You can put it back; I won -(TM)t be mad. - -No, I can -(TM)t. I almost came just from having the tip inside you for only a second or two. If I penetrate you again I -(TM)m going to cum almost instantly. - -Oh, so that -(TM)s what you meant by not safe. It -(TM)s OK. My periods were all over the map, fifteen days apart, then forty-five, sometimes as many as sixty days between cycles. Mom took me to the doctor and they put me on the pill to stabilize my schedule. - -So you mean, we can have sex safely? - -Yeah, Mike, you can have sex with your little sister without worrying about knocking her up! - I just grunted and tried to get my dick back inside Tanya. Of course, now that we were both trying, my cock didn -(TM)t want to enter her. -Shh, just calm down Mike. Try grinding your shaft on me like you did before. - I did what Tanya told me, and my cock was so hard that it was physically painful, but I couldn -(TM)t have stopped even if someone had irrefutable proof my dick would fall off if I didn -(TM)t. It really did feel that good! Then Tanya shifted subtly, and I was inside her again! I barely had time to register what had happened before my cock started exploding cum inside Tanya -(TM)s pussy. I tried to get more of my cock inside her briefly, but that hurt too. So I just froze and pumped cum into my sister with barely more than the tip inside her. I know I had never come that intensely before, not even when I had cum from sucking on her tits earlier in the day. When I finally stopped cumming, I looked at Tanya and saw a funny look on her face. -What? - I asked. -What do you mean? - -Why are you looking at me so strangely? - -I don -(TM)t know, I -(TM)m just really satisfied. I was so proud of myself when I could tell you were ejaculating inside of me. Oh fuck, you ejaculated inside me! That means we just had sex. I just had sex with my big brother, and I said that made me proud of myself! - Whatever hormone cloud that had made Tanya want to get my cock inside her seemed to have dissipated. I didn -(TM)t understand. She had told me it was OK; she had needed me inside her. She had even helped me get inside her, but now she was pushing herself away from me. My cock came out of her body releasing a pool of our mingled juices onto the stone we had been sitting on. My cock was limp and also dripping white goo onto the stone beneath us. I whimpered as her panties slid to cover her pussy again, but I consoled myself by staring at my sister -(TM)s big jugs. I tried to get her back to the mood where she enjoyed having my cock inside her, -Any time you want to feel proud of yourself again, just let me know. - -Damn it Mike, not now. You didn -(TM)t do anything wrong, or at least nothing more wrong than what I did, but shut up about it for now. I -(TM)m kind of freaking out and don -(TM)t want to talk about what just happened. - Well, that hadn -(TM)t gone well, but I was having a hard time feeling anything but happy. I had just shot my wad inside a girl for the first time, and i didn -(TM)t care that it was with Tanya. In fact, the more I thought about it, the more I was glad my first time had been with my sister! Chapter 9: Tanya Needs More The first half mile or so, it wasn -(TM)t hard to walk in silence. I was content reliving my first time having sex with my sister. I pondered things like I put my dick in, then pulled it out, then put it back in again. Did that mean I had sex with Tanya twice, or did it not count because I had only cum the one time? However, after about 10 minutes on the trail, I was getting horny again, and I wanted nothing more to touch and kiss, and even fuck Tanya again. And that was even with Tanya putting her sports bra back on and throwing the tiny crop top back into her backpack. I could understand why she was freaking out, but all I wanted to do was fool around with her some more. Now that I knew what magnificent tits were hidden under the tight sports bra, Tanya just looked different to me, sexier even when not showing off. However, I didn -(TM)t want to make my sister uncomfortable by talking about things she didn -(TM)t want to talk about, so we walked without saying anything to each other. Still, the rest of the trip downhill became filled with uncomfortable silence. It made for a long three miles, and even though gravity was working with us, we didn -(TM)t make nearly the time we had heading up the trail. We must have been getting close to the point where our trail rejoined the main one back to camp because I noticed a fragment of conversation on the wind. It was then that Tanya surprised me, -Turn around. - -What? - -Turn around, go back up the trail. - -Why? - Tanya didn -(TM)t answer directly. Instead she stepped close to me grabbing my crotch with one hand, -Turn around and go back up the trail. - My cock hardened pretty quickly in my shorts, and I just said, -Oh! - and started walking. I didn -(TM)t say anything immediately, but soon asked, -So what changed your mind? - -I blame you for this. The more I walk with your cream inside me, the more I want a second helping. For the first half mile, I was really angry with you for starting this whole mess off by asking to touch my boobs. But then you actually listened to me, and stopped talking about what happened. That made me angry at myself for letting things get crazier and crazier. Then that faded to annoyance that my brother had popped my cherry, and that faded to indifference as I considered that no one else would ever know so what did it matter? Then my pussy started to feel tingly, and I began to think maybe it wouldn -(TM)t hurt to get one more dose of your cum. I -(TM)ve spent the last mile getting hornier and hornier thinking about letting you dump another load of jizz inside me! - My cock had softened a bit from when Tanya grabbed my crotch, but after hearing those words, it surged with a vengeance. When I looked at Tanya, her eyes were half closed, and her face looked similar to when we had been making out. -I mean, seriously Mike, what have you done to me? At the top of the trail I was sure it was a one time experimentation with incest. Now down here at the bottom, I -(TM)m not sure I could make it through dinner without another dose of brotherly love before we get back to camp! - I swept Tanya up in my arms, and she let me kiss her. However, when I started trying to get her out of her clothes, she protested. -Not here, lets get over to that tree off the trail. - It was a scraggly thing with sparse leaves, but we both raced for it. Tanya reached the tree first, and bent over at the waist bracing herself against the tree with both hands. I came up behind Tanya, and this time when I tried to unsnap her shorts, she just made happy noises. I pulled off both shorts and panties, and she wiggled her hips to allow them to fall to her ankles. Then she stepped out of them and spread her legs invitingly. I undid my fly and fished out my hard cock. Fully able to see what I was doing, I tried rubbing my cock on the outside of Tanya -(TM)s pussy again. -Mike, what are you doing? Trying to make me go insane? I need you inside of me! - She said while shifting her hips uncomfortably. Still, I didn -(TM)t try to penetrate Tanya just yet. I was still nervous about how quickly Tanya -(TM)s pussy had made me cum earlier, and I was trying to really rile her up before I put my dick back inside her. However, once again I slipped inside my sister without meaning to. Her pussy seemed to have some magic quality that could pull my cock into it even when I was trying to keep my dick on the outside. This time, knowing Tanya was on the pill, I didn -(TM)t try to pull out, but instead got an even better grip on my sister -(TM)s tiny waist and tugged on her hips. -Fuck Tanya, that feels so good! - -It does, it really does, - Tanya whimpered. I felt the urge to cum rising in me again at even the first slow, experimental tries at actually fucking my sister instead of instantly dumping my load inside her as soon as penetration occurred. So I stopped fucking and bent over double myself so I could whisper to Tanya, -I love you little sister. - -Mike, you can -(TM)t try to make this romantic. We -(TM)re just two horny teens getting our rocks off with some incest. - -Sure I can, I love you little sis, and I love it even more that I can show you how much I love you with my hard cock! - I couldn -(TM)t interpret the noise Tanya made after I said this to her, but I needed to pump my sister hard and I needed to do it now! I stood up and started tugging on Tanya -(TM)s hips urgently as I sawed my cock back and forth inside her as fast as I could. With every thrust, I could feel Tanya -(TM)s pussy working to get me to spill my seed. This wasn -(TM)t like jacking off at all, where I could tug on my dick for quite a while before I came. Tanya -(TM)s pussy was far too tight and hot for me to last inside her. -Ugh! You -(TM)re pussy is too irresistible Tanya, I can -(TM)t help but fill it with my ... cum ... again. - I grunted as I pumped my seed into my sister a second time. This time with my cock buried as deep inside her as I could manage. When I stopped grunting, Tanya told me, -Don -(TM)t pull out Mike, I want to feel you inside me as long as possible. - She didn -(TM)t have to tell me twice. I doubled back over and wrapped my arms around Tanya and whispered in her ear, -So how do you like me showing you how much I love you with my cock? - -I know I -(TM)m not supposed to say this, but I -(TM)m not going to fight these feelings any more. It -(TM)s fantastic Mike, that -(TM)s why I told you not to pull out. I -(TM)m so happy right now! I felt like I was going to melt when you insisted you could be romantic with me. - That was music to my ears, and I flexed my half hard cock inside her body causing Tanya to squeal with delight. I -(TM)m not sure how long we were joined like that, but eventually my cock became completely soft and it slipped out of Tanya -(TM)s pussy causing her to make a disappointed noise. -I guess we should head back to camp before Mom & Dad send someone to look for us. - -Yeah, - Tanya agreed. -And we -(TM)ve got to be cool. No making lovey-dovey eyes at each other or stealing kisses when we don -(TM)t think our parents are looking at us. We -(TM)ll get busted for sure if we try things like that. And make sure that the camera is set so that they can scroll through the photos without hitting the spicy pictures of me. - -Spicy? - -Topless you clueless perv. - Tanya said hugging me. However, she almost instantly started moaning and rubbing her chest against me. It had me now wishing I had tried to get her out of her shirt and bra before I had started to fuck her, but I realized that the lure of her pussy had been too strong for that. -This is being cool? - -It -(TM)s not fair, you -(TM)ve gotten your rocks off three times, I haven -(TM)t once. Not that I -(TM)m complaining; everything you -(TM)ve done with me has felt incredible, I just haven -(TM)t gone over the top yet. - -I could eat you out, - I offered. I was really curious to experience that. -No, we don -(TM)t even have a good place to sit on this part of the trail. Just stand behind me and use your fingers. I did what Tanya asked, and she started moaning like crazy just like she had when I put my hand in her panties earlier. Then she really started whimpering when I got half of my index finger inside her. -How -(TM)s me showing you some brotherly love with my finger working for you? - -It -(TM)s not as good as your hard cock, but it -(TM)s getting the job done, - Tanya giggled. I kept working my sister over with my wriggling finger. I would move it faster and faster as long as she seemed to be getting more excited. Then when she stopped reacting as strongly, I would stop moving, then slowly start using my finger more energetically again. One time when Tanya seemed particularly close, I tried to get all my finger inside her. All of the sudden, I was holding Tanya up as her legs buckled. -Fuck, I needed that. Oh how I needed that. Now I think I can play it cool in front of the parents. - Chapter 10: BJs in the Tent My ruse of taking several pictures with the lens cap on had worked. We had been able to show our parents the pictures I had taken at the scenic lookout on the camera -(TM)s view screen without trouble. Tanya stood off to the side while our parents had the camera obviously nervous that they would see topless pictures of her, but they never even scrolled back into the ones taken with the lens cap on. Then they asked us several disbelieving questions about the steep trail we had hiked. In a way, the fooling around we had done worked in our favor. The speed with which we had rushed up the trail was countered by the amount of time we had spent feeling, kissing, and fucking each other. I was pretty sure our parents would have never expected that. For that matter, I would have considered that an impossibility myself earlier today. And there is absolutely no way I -(TM)d have ever thought we -(TM)d end up having sex twice while hiking, even if you had told me at the start of the trail that Tanya would let me feel her up and kiss her. The evening in camp was both nice and torturous at the same time. I really wanted to get Tanya back in my lap, or to make out with her again, but we couldn -(TM)t do that with our parents around. I was kind of hoping that our parents would head to their tent early, but when they stayed up watching the camp fire, that hope was dashed. When Tanya went into her tent, I decided there wasn -(TM)t much point in staying up either. I was hard and horny laying in my sleeping bag, but I didn -(TM)t really want to jack off in hopes of doing something with Tanya again. I was probably more tired than I had realized from the hiking because I fell asleep in my tent even as horny as I was. I woke up to the feeling that only my dick and my feet were warm. It hit me suddenly how good my cock felt. It was super hard and wet, and something soft was moving up and down it. It didn -(TM)t quite feel as good as fucking Tanya had, but it excited me greatly and I felt the urge to cum rising suddenly. I arched my back and tried to groan, but a small hand covered my mouth to quiet me. Then the amazing sensation on my cock was gone. I heard Tanya whisper, -Hush, I did this to keep Mom and Dad from hearing anything. - Still groggy from being awakened this way, I tried to say -What? - with Tanya -(TM)s hand still covering my mouth. She must have understood me, because she answered. -Preemptive blow job. If you had snuck into my tent and wriggled your hard cock between my legs, I -(TM)d have been screaming my fool head off before I was awake enough to realize I needed to be quiet. I don -(TM)t think you can think about anything but pussy once you get your cock inside me. - -Boobs, I -(TM)ve still got some brain power for appreciating how nice your tits are while I -(TM)m screwing you sis, - I whispered back. -Thanks, I think. Anyway, I still don -(TM)t trust you to be quiet, so... - I felt my sister -(TM)s hand cover my mouth as she lowered her own mouth onto my hard cock again. Now that I knew I was getting a blow job from my little sister, the sensations felt even more amazing. I wanted the first time my cock got sucked to last forever, but I knew that wouldn -(TM)t happen. The urge to fill my sister -(TM)s mouth with my spunk was just too strong. My body stiffened uncontrollably again, and it was a good thing Tanya had my mouth covered, because I would have cum noisily without it there. Rapid fire pulses in my hard cock pumped semen into Tanya -(TM)s mouth, and I could feel her sucking and swallowing my load. Now that my cock had been relieved, Tanya removed her hand from my mouth, and I sighed, -That was amazing Tanya; you have no idea how badly I needed that. It was almost torture not being able to wrap my arms around you in front of the camp fire. - -No, trust me, I could see it in your eyes. It was hard for me not to just melt into your arms. It some ways it feels weird to crave my big brother -(TM)s touch so much, and it others it seems like the most natural thing in the world to just snuggle up next to you. Speaking of snuggling, can I get into the sleeping bag with you? I -(TM)m a little chilly. - -Of course, it is a bit cool tonight. My first thought when you woke me up was that only my feet and cock were warm. - As Tanya climbed into the sleeping bag with me, it occurred to me again how much I loved my little sister. -Damn, Tanya, I -(TM)m going to need to do this with you every night. - There wasn -(TM)t really anywhere for her to go, but I was panting trying to pull my sister even closer to me inside the sleeping bag. And this was with a soft, satisfied cock. I really wasn -(TM)t sure how I was going to manage to behave at home if I happened to pop a boner for my sister. -I -(TM)ll cuddle up with you like this any time I think we can get away with it, - Tanya whispered in a way that sent chills up my spine. I wished Tanya had been naked, but it was still wonderful to pull her nightgown clad body close to mine. Having just been blown, I was soon dozing off with my sexy sister in my sleeping bag. I was so satisfied zipped up in tight quarters with my sister -(TM)s warm, soft breasts pressed up against me. The next thing I knew I heard Tanya whispering, -Hey, wake up. - -Huh? - -You dozed off, and I almost fell asleep too. That would be a disaster if Mom & Dad found us like this tomorrow morning. I need to go back to my tent. -Awww... - -Don -(TM)t whine. I want to blow you again before I go. - That caused me to make a very happy noise. It took a bit of unzipping and moving around, but soon Tanya had my half hard cock in her mouth. I tried to tell myself that it was no big deal that was what my little sister was doing to my dick. Once again, I wanted this experience to last as long as possible. I tried to keep my cock from going fully hard, but Tanya -(TM)s sucking felt so good! I groaned as I couldn -(TM)t resist my sister -(TM)s cock sucking skills, and my dick swelled and stiffened as her lips slid up and down my length. I felt Tanya -(TM)s hand cover my mouth again and I switched my focus from not becoming hard to not cumming in her mouth. That urge wasn -(TM)t any easier to resist. Tanya was doing such an amazing job of sucking my dick, how could I not want to fill her mouth with my seed? It was inevitable that she would trigger another explosive release of cum into her mouth, why should I fight it just to eek out a few more seconds of pleasure? I should just surrender to her sucking now and give my little sister the cum she obviously wanted me to shoot. My cock became even harder and pulsed urgently as I release hot white cream into Tanya -(TM)s eager mouth. My brain started shutting down so quickly after this orgasm I didn -(TM)t even try to follow Tanya out of my tent to try to steal a few kisses before she went back to her own tent.
