When she came over to give me the juice, she sat down at the table and started to have a conversation with me. We talked about her boyfriend Chris, and what a lame ass he was. I had to agree. When I turned sideways to look at her, my blanket fell open, and there i was exposed.

          " Whoah, Andrew, put that away." she said. " I dont want to see your dick right now, with all that hair!"

           I hastily covered myself, embarassed, but somewhat turned on. I found it erotic that my sister had just seen my genitals. At the thought of this, my dick started to get hard. Soon, it was stiff and I was sporting a tent out of my blanket. My sister looked down at my crotch again, and with a slight smile said, " well bro, I guess the thought of being exposed to your sister made you a little bit horny".

        I then said jokingly, " yeah, and since it's my birthday, i wouldnt mind getting some bitch to suck me off, you got 5 dollars?"  She said, " why spend 5 dollars on a birthday gift, when you could get it for free?"

             " how could I get it for free, not many girls go for me, I guess i'm not their type." I lamented.

            She placed her hand on my knee and started to gently rub little circles on it. " oh, plenty of girls are interested in your type, you're just too shy to see your oportunitys."

           She then said," well, since it's your birthday, and nobody else is awake, howabout I help you gain some self confidence?" I was unsure of what was going on, but I eagerly consented. She slowly pulled the blanket off of my lap, and let it fall to her feet. There I was, my newly trimmed bush, and 7 inches of dick standing up stiffly. She said " not a bad size here, bro." She then pulled knelt at my feet, rolled her sleeves up and spit in her palms.

            " I think you're going to like this birthday present, Andrew" she smiled up at me. She then grabbed ahold of my dick and slowly felt my ridges and veins. At the feeling of her hands on my penis, I accidentally flexed it and pre-lube came out of the tip. She quickly swept that up with her tongue. At the feeling of her tongue on my dick, I flexed it even harder and more leaked out.

             " I guess you're going to be too wet for me to just clean up with my tongue, so i'll have to use my whole mouth," she said playfully. she placed one hand on the inside of my thigh, and the other on my smooth balls and gently slid the tip of my dick into her mouth. I looked down and just seeing the way her mouth was swollen with my, MY penis almost got me to shoot right there. I was her brother, and she was doing this, it was awesome! she got down to about 4 inches down the shaft, and i felt my tip hitting the back of her throat. I grabbed the back of her head and rammed the other 3 inches down her neck. She gagged slightly, but didnt choke or anything. After i was fully nestled in her throat, she just looked up and me and nodded. i took that for confirmation for anything i wanted to do.

               I wrapped my hands in her hair, and started to slowly pump in and out of her mouth. i brought my dick from balls deep in her mouth, the just the end of it left in her mouth. She just looked up at me, and kept sucking as hard as she could. Eventually i could fill the cum about to burst out of my dick, i started to ram into her face as hard as i could, my balls were slapping the bottom of her jaw, and she was getting a nose full of my pubes each time. I then squirted my first jet down her throat, and pulled out right as she was swallowing, it came out and splattered all over her lips, and then squirted up and got her on the bridge of her nose and in her eyelids.

               She looked up at me, smiled, and wiped the cum off of her face and ate it. " mmm, you taste good Andrew, now howabout you get a feel of all of my body instead of just my mouth?" she then stripped out of all her clothes. as she unclapsed her bra, i was just struck with awe. those 32 d's were so awesomely proportioned it was almost unbeliveable.

              By the time she was undressed, i was fully hard again. she came over, and pumped me a few times to get me to maximum size, and gave it a kiss. She then turned around, and got on her hands and knees,and said " what are you waiting for, havent you wanted to fuck this ass for a while?" i said " i must have came in my bed at least a dozen times from my wet dreams of you". i then grabbed her waist, positioned my dick in her pussy, and slammed it in in one large thrust.

            " easy andrew, i havent had sex in a while, i havent been stretched out yet". I just ignored her and kept up my pounding. this was my first pussy, i was going to have it my way. everytime my pelvis hit her ass, her tits would swing up and knock her in the face. I decided to fix that problem and get a palmfull of them. There i was, fucking her doggy style and using her tits as leverage. i started to cum for the second time that night, and as i squirted in her pussy, i felt her lock up and squeeze me really hard, then a flood of pussy juice drenched my legs and bed. We ended up being so exausted and tired from that fucking that we were both on the ground, my on top of her and still inside her. eventually i grew limp and i rolled over.

              when she got up, she kissed me and said "happy birthday bro, wait till christmas..it's going to be wild" i stumbled into my bed and fell asleep with the biggest grin i've ever had in my life on my face. Happy birthday to me.

Yeah, it really is my birthday though.

“Let’s just hope she doesn’t ruin our whole trip” I replied.

    The ride to the lake was cramped as all we all wanted to get out, but whatever, me and Chris made the best of it.

   < I’m going to skip the boring 2 days leading up to this one  glorious night>

    As we all finished up dinner, Jessica went to bed early, to get settled in. Chris and I went down to the public showers to wash the sweat off of our  balls, (it was a hella hot day). We brushed our teeth, and then went back into the campsite, and went into our tent. I guess me and Chris thought something would happen that trip, because we set our tent way in the back of the camping lot, a good 100 feet away from the other camping members. As we settled in for bed, we discovered that Jessica wasn’t asleep yet, and that she was only wearing a night gown.

    As we settled in, we started talking to Jess about something, I don’t quite remember, but it led to the topic of her breasts. Chris led us off. “Jessica, you have some pretty small boobs.” He exclaimed. I immediately concurred, “Yeah, Jess, even I have bigger tits then those itty bitty tittys.” “ I do not, you jerks!!!” she said. “Oh yeah, then why don’t you show us how big your tit’s really are”, we said. I don’t really want to, guys. That’s because you really do have small tits. With that said, she became so indignant that she actually believed that she had to prove us wrong!!

    She took off her night shift and showed us her extremely perky tits. Almost immediately we closed in on her. This was not the first time we used this type of maneuver, but it was the first time that we used it on one of our many family members. We both took a breast, and started to bite and lick it. She started to giggle and groan. She pushed us off because she said that it tickled her. After that, for some fucking reason she chose favorites, and singled Chris out for a one on one session. Chris began to mack out with her. The both forgot me, but I was content to sit and rub my dick while they were going at it. Chris took off her pajama bottoms, and was rubbing her plump titties and fingering her pussy.

   “Damn, this bitch is  WET!!” he exclaimed. I guess he got her really riled up, because she broke the contact, and got down to Chris’s boxers. She slid them down his legs, and his 7 ½ dick rose up and popped her in the eye. She fucking cooed to that schlong, and tentatively licked the tip of his dick. He started to quiver, because this was our first experience with incest, or at least this degree of incest, you know how kids play “doctor” and shit like that, well now we were teenagers, we knew how to use our “peters”. Jessica wrapped her soft hands around Chris’s hard, throbbing shaft, and worked them up and down. She was amazed, this was the first dick she had felt, even seen from this close.   

    Yeah, she had peeked on her brother in the shower, jacking off, but this was different, this was real. She stopped gliding her hands over Chris’s shaft, and Chris told her he would take it from there. He grabbed the base of his dick, and slid his cock over her lips and her cheeks, smearing pre cum everywhere. He then grabbed the side of her head and slowly inched her face onto his dick, until her nose was firmly buried in his pubic area. He then guided her back off, to the tip of his dick. “Ohhh god, this is good,” he moaned. “Suck it baby, don’t just let me fuck your mouth, suck my dick baby!!!”

   She sucked his dick so hard she looked like a fish. She looked up into his eyes, removed his hands, and started to move back and forward on his dick all on her own. She started to cup and fondle his balls, which must have been damned near blue by this time. All of the sudden, Chris stiffened up, and grabbed the back of Jessica’s head and pushed his dick down her throat until her nose was firmly nestled in his pubes, and released a torrent of liquid hot jizz rushing passed her tonsils.

   At first she panicked and tried to pry herself off of him, but he just held on, and eventually she learned to keep swallowing. You could see her throat swallowing about 10 to 15 times before he relented. As she pulled her mouth off of his cock you could see a string of cum from the tip of his dick to her mouth. She gave his cock one final lick and said “thank you”. Well damn me if I didn’t want my turn by then. My fucking dick was purple by that time. “Well Jessica, are you ready for your big brother?” I whispered. She just nodded her head, with a glob of cum reaching from her cute lips to her ear. At that moment, she was completely adorable. She was stroking her pussy as I made my way across the air mattresses. I came over and asked her to start me off by sucking me. I even used the best pick up line in the world... “Blow me, beautiful.”

   She worked her hot mouth up and down my 7 inch shaft, until it was thoroughly glistening with saliva, I then pulled it out of her mouth, there was still a string of spit from her mouth. I flipped her onto her stomach. She automatically knew what was wanted, and presented her perfect heart shaped ass into the air. I couldn’t resist, I dove into that honey pot and started to lap away at her hot pussy. I pulled her pussy lips apart with my hands and used my tongue to bump and lick her clit, after a while, she began to buck and moan until she exploded pussy juice into my face. It was my turn now. As I ploughed into her not so virgin pussy, she immediately started a voiceless shriek. Her pussy was so hot it was unbelievable. “do you fucking like your big brother boning you?” I grunted, as I lifted myself and drove into her vagina over and over.

    I almost blew my load, but I had other plans. I pulled my glistening dick out of her raw pussy, and called Chris over. By this time, he was already sporting another hard on, so I told Jess we were going to double team her. By that time she was biting her lip and begging for me. We were happy to oblige. We rolled up a sleeping back, and had me sit on it. As I sat with my dick straight up, Jessica came over and sat on it. My dick rammed right up her ass hole, and she loved ever second of it. Then Chris came over and lay under the sleeping bag. I lowered her down so that her pussy gripped Chris’s dick like a vice, and I was sitting across his legs.

    We then started a see saw motion. I fucked into her, and that drove her pussy onto Chris’s dick, then he took the oncoming momentum from my thrust and drove deeper into her, and his thrust shoved her ass further onto my dick. It was beautiful. She started to moan very loudly, good thin that we were so far from our parents, and eventually the throbs from her ass and pussy muscles were too much for me and Chris, and we filled her body with at least 2 days worth of man cream. We all fell down, limp noodle style, and took a breather. As me and Chris lay down, she came over, and gave both of our dicks a final suck or two, then redressed and went to sleep. That was pretty much the best bonding experience that I can think of.
