Treehouse part 2 (mf) (Young guy finds his sister is hotter than hot} I was sitting in my treehouse doing nice things to myself when my sister Sarah came up. I hadn't noticed how hot she was. But now she had her hands grasped around my huge cock (enormous for a boy of my tender years) and she was gently massaging me. The aroma of her sexiness was apparent and made me even harder. As I only had my T-shirt on, I felt very exposed, but as she bent her head down and began to play with the head of my cock with her tongue, I forgot all about things like that. Lights went on in my brain and my cock began to pulse wildly in her hands. "Sis, that's soooo good!" I managed to say as she opened her mouth and tried to get the big head of my cock between her lips. "You are just so big!" she squealed, with pleasure. "Don't want to hurt you, little bro!" I could only groan as she struggled and eventually managed to open her mouth wide enough to take the head inside. She mumbled something, but with her mouth now filled with my cock, it was completely unintelligible. It was an amazing feeling. The only thing that my hard cock had ever been inside, apart from my own clothes, were her silky panties while I was jerking off. Now I had the delight of a soft warm mouth surrounding my cock. Delicious can't even try to describe the feeling. I wanted to just push my cock right to the back of her throat and spurt her stomach full of my steaming cum. But I was inexperienced in these matters and just looking down at her sucking my cock with obvious pleasure sent me over the edge. I just had time to grunt "I'm cumming, Sis!" before my cocked bucked like a wild thing in her hands and began to shoot out hot stuff into her mouth. After the second spurt, I think, she jerked her head off my cock, my stuff pouring out of her mouth. She jerked madly at my shaft as it continued to spurt out more and more huge fountains of stuff. Sarah sat back, with my cock still throbbing in her hand as the spurts slowly began to subside and finally end in a dribble. She was covered in it, all over her top and skirt, even up the insides of her long thighs. I thought just how awesome she looked and I wished I had a camera to capture that moment. "Little brother!" she gasped, still trying to wallow the mouthful of stuff, "That was amazing. You cum so much!" "You made me, Sis!" I chuckled. :Thanks!" "Oh no!" she cried. "Look at my clothes. What if Mum or Dad come back?" "It's OK, Sis," I calmed her. "They're out until after lunch. They told me that!" "Problem is, I'm now hot as hell and I don't think my bro knows how to please a girl - yet!" she said, disappointed. "But maybe you'd like to learn?" Before I had time to reply, she stood up in front of me and began to unbutton her cum-stained top. I was instantly hard again, not that my cock had retreated too much anyway. My sister was doing a strip for me! Wow! This was becoming one incredible morning! Her small but perfect boobs came out into the light. She wasn't wearing a bra, - her boobs just stood tight and firm on her chest. I immediately noticed that her nipples were hard, not that I'd ever seen real nipples before, but I knew that's what happened to girls in porno movies. I so wanted to touch them, to feel what other guys were probably dying to feel - my sister's sexy tits! But again before I had time to do anything, she'd shrugged her top to the floor and began to unzip her short skirt. There were drops of my stuff all over it, so it would have to go in the wash anyway! Down it fell to the floor - my awesome sister was now standing so close to me, dressed only in a tiny pair of pink panties. She looked gorgeous - like a sex goddess...and I think she was very hot for me at that moment! Again, before I could move, she'd grabbed the waistband of her panties and begun to push them down her legs. For the first time ever in my life I could see a girl's pussy...and there was no hair...she shaved herself there! "Like what you see, little bro?" she murmured, throwing the panties on the chair and smiling sexily at me. "You are...truly...beautiful," I managed to stammer as I looked first at her pussy, then at her tits, then at her smile. "Thanks, bro," she giggled. "Now move off the bed and let me lie down. I'm gonna show you how to make me happy!" "You mean you want me to lick your pussy like those guys in the movies?" I asked, surprised that she'd let me do that to her. "Yea. Just like that. Well, actually, rather more like the girls do. Guys are usually too rough for me," she grinned. She looked up as she lie on her back on the bed, spreading her long legs apart for me. I was standing at the bottom of the bed and gazing in total awe at my first sight of a delicious girl's open pussy - in real life. Lying like that, she then put her hands on her boobs and began to play with them. "Can you see, little bro?" she asked. "I'm all wet and ready!" I could see some sort of white cream around her pussy lips and more seemed to ooze out as I watched. My cock throbbed incredibly as I could not take my eyes from my beautiful sister. "Oh, yessss. I can see. Is that coz you're so horny?" I asked her with a grin. "Yes, Little bro. And you've made me that way. Do you think you'd like to lick my pussy?" I just moaned with pleasure, kneeling down on the bed between her outspread legs. "Now go gently. Not rough. I like it to take a real long time," she urged as I slowly lowered my head towards her upper thighs. "Do guys like doing this to you?" I asked quietly. "Only one has done it - so far. But my girlfriends love it. They say I taste good!" My lovely sister put her hands on the back of my head and pressed my face down towards her pussy. The smell of her sex was awesome and my cock was pulsating wildly. I guess it wanted to get in where my tongue was about to go. Now I don't know whether fate intervened at that moment or not, but...there was suddenly a shrill cry from below the treehouse. "Sarah? Sarah?" the female voice called. "Are you up there?" "Damn, damn, damn!" cried my very horny sister. "What the hell is she doing here at this time?" "Who is it?" I asked quietly, looking nervously towards the treehouse hatchway, which was closed again and the rope ladder properly stowed away. I breathed calmer now that I'd checked, but so much had happened that I couldn't remember shutting it. "It's Mandy, the bitch!" cried Sarah, hurriedly standing up and slipping into her skirt and top. She went to the hatchway and opened it slowly. "What do you want?" she cried down at the invisible Mandy. "Oh, spoiled your party, have I?" came the girl's voice. "And you forgot to put your panties back on!" The girl laughed and Sarah looked back at me embrarrassed. "OMG, so I did!" she cried glaring at me. There was nothing I could do about it, so I grabbed her panties and wrapped the round my still hard cock, with a malicious grin. Sarah stared at me, then giggled. "Do you want to come up, Mandy?" she invited, her tone much gentler now. "My little brother has been showing me why he likes to be in his treehouse so much." "OK" agreed the girl from below. "Let the ladder down then." Sarah flicked the clip that held the ladder inside the hatchway and watched it fall downwards. "Got it!" cried the girl. "I'm coming up!" In less than a minute, the blonde head of my sister's friend, Mandy appeared in the hatchway. She immediately looked around until she saw me. I was still dressed in just my T-shirt, sitting on the bed with Sarah's panties wrapped round my cock. I guess it was quite a sordid scene. "You are right!" cried Mandy, in a shrill voice. "It's huge!" "OK, Little Bro. Now you've impressed another girl!" chuckled Sarah as she helped Mandy pull herself into the treehouse. Mandy could not keep her eyes off my cock as I slowly stroked it with Sarah's panties. "Does he do that a lot?" she asked her friend, moving close to her and then suddenly kissing her on the lips passionately. "Apparently. That's why so many of my panties have gone missing for a while, to return later. And also why I've found so many new pairs!" Sarah's eyes were alight with lust as she broke away from her close friend (and from what I'd just seen, probably her lover too). "Will he do it for me?" asked Mandy, grinning. "I think Little Bro would do it for just about anyone!" cried Sarah, pushing me back onto the bed. My cock stuck vertically upwards as Sarah grabbed at my shaft and began to massage it. "I've just made him spurt and he was about to lick me, when you arrived," she explained, looking a little disappointed. "Well, how about letting him lick us both while we play with that monster you're holding?" suggested Mandy. "How can we do that?" Sarah asked, surprised at the suggestion. "Sit on his face!" said Mandy, with a giggle. "You'll drown him when you cum!" warned Sarah. "I know, but he'll love it!" the young girl cried. I guess I'd better fill you in on what Mandy looked like. She was a little older than my sister, very full chested. She was wearing a small top and tight shorts, a bit like a young guy's wet dream. As she was speaking, I'd noticed her nipples getting hard underneath her top. Then with a flourish, she pulled off her top. "If you're not going to start, I am. Just thinking about that enormous cock has made me so wet," cried Mandy, now pushing off her shorts. She wasn't wearing panties so now she was almost instantly naked in front of me. My cock throbbed wickedly and she noticed. "I think Little Bro is horny again!" she cried with a giggle. Sarah looked at me, then at Mandy and grinned. She quickly pulled off her top and dropped her skirt to the floor. Now I had two naked girls beside me on the bed! Somehow I'd dropped Sarah's panties and my cock was now standing upright just in front of the two older girls. There was a drop of clear pre-cum at the tip. I wanted Mandy to lick it off, but I didn't dare ask her. Then first Sarah followed almost immediately after by Mandy, put one hand each on my cock shaft. I groaned noisily and smiled faintly at them both. "It's just huge," gurgled Mandy, struggling to get her hand right around my cock. "Yea, great, isn't it?" agreed Sarah, slowly beginning to stroke my shaft up and down with her warm hand. "Did you get it in your mouth?" Mandy asked. "I struggled, but just about managed it, then he began to spurt - he went everywhere - all over my clothes and me..." "Hey, Little Bro, have you got as big a load for me to see?" asked Mandy with a wicked glint in her eyes. I just moaned again as by no both girls were gently stroking my throbbingly hard cock. "It's like milking a cow!" giggled Mandy, "except it's much harder!" "And it bucks like a wild thing when it cums," Sarah added, grinning at me. "Are you close yet, Little Bro?" I just about managed to groan and nod my head, although an orgasm was as far away as I could imagine. I was having far too much fun to cum - just yet. At least, that was my thoughts. But then Mandy moved her head down towards the top of my cock. I almost groaned, "Oh no!" as she opened her lovely mouth and tried to push my cock inside. "He's just too big!" she cried as she pulled back. "No, he isn't really," said Sarah, pushing her wide open mouth onto my cock head. She managed to get the tip inside and then gasped for breath. She tried to say something, but it came out muffled. Well, she did have a big mouthful of cock! "Let me try again," pleaded Mandy as she pulled Sarah's mouth off. This time, her warm mouth did get the head of my cock inside and even more she managed to push her mouth at least 10 cm down on my cock. The feeling of such a tight wet mouth on my cock was incredible and I suddenly felt my orgasm was not that far away after all. "Awesome, Mandy," grinned Sarah as her friend smiled and looked at her with a feeling of achievement. Both girls were still stroking my cock shaft with practiced hands and the feeling of Mandy's tongue, which began to throb along my shaft and cock head began to build me up really nicely. "Why don't you sit on his face?" suggested Mandy to Sarah, "while I make a meal out of this magnificent cock." Sarah giggled. I knew she was absurdly horny by now and I could almost feel her wetness on my tongue. However, I was not prepared for her when she did sit across my face. First, as she straddled across my chest, I got an amazing view of her very wet pussy, opening up and almost begging me inside. My cock pulsed viciously in Mandy's mouth and hand and the girl squealed with pleasure. Then Sarah moved upwards and I could smell her incredible aroma. I watched in awe as she lifted herself up and brought her pussy towards my mouth. As she got closer, I tried to bend my neck upwards to taste her, but soon she was sitting right on my face, my tongue slipped right up inside her pussy and I could finally taste my sweet sister's horny juices. She was so wet that I was soon covered in her juices and I could feel them dribbling down the sides of my face. "Ahhhhh," groaned Sarah as I began to slide my tongue in and out of her pussy. "He's doing it, Mandy!" Mandy could only grunt as she refused to take her mouth from my cock! Her hand moved a little faster as she felt my shaft swelling. I was going to cum - hard - and for the second time today inside the mouth of a gorgeous young girl. Sarah shifted herself on my face, so that my tongue pushed against the hard button which knew must be her clitoris. As I began to play with that button, she moaned and cried, urging me on. Now my orgasm built very rapidly and I began to buck my hips upwards, pushing Mandy's mouth even further onto my cock. She gagged and tried to move, but I grabbed her head and pushed it hard down onto my cock. Somehow, my cock slipped deeper inside her mouth, maybe into her throat as she adjusted the angle. Well, that did it, with Sarah crying out to cum on my tongue and Mandy stroking my cock with her mouth and hands, I erupted like the proverbial volcano. The first shot went straight down Mandy's throat and she couldn't breathe. She just had to let my cock out of her mouth. Then it became uncontrollable as my hot stuff spurted all over her and Sarah. This feeling must have sparked off Sarah's orgasm as almost immediately my face and mouth were flooded with a huge quantity of her juices and she cried, almost screamed, as she came. I managed to lick up a lot of her cum juices, but I felt that the bed was soaking wet now. When Sarah finally moved to sit beside Mandy and me, I could see that her back was covered with my stuff. Drops of it were also all over Mandy's boobs and belly, even dripping down between her legs. 'That's an ocean of cum!" giggled Mandy as she used her fingers to scoop some from her breasts and taste it. "Mmmmmm, yummy!" She took some more and soon her and Sarah were almost fighting over the drops of my cum that were spattered all over their bodies. being continued...
