My not so innocent little sister

Ahhh,another beautiful day,sunny,hot,no school and we had an awesome swimming pool that my little sister and I and lots of her sexy friends,loved hanging out around all day and nights.I was 16 and cary was 14,almost 15 as were her friends.
All of these girls were filling out real nice and of course they were boy crazy.I don't think any of them were dating so I ended up as the main topic many times.It was great and I was surrounded by girls in sexy swim wear all the time.I had a rather large cock for a 16 year old,8 girthy inches,and I wore speedos just to show it off.
The girls were staring at my crotch all the time,including my sister.Sis was the sexiest in her bikinis and her body was maturing nicely.
Many days,we were home alone and when we were in our suits out at the pool,I found it difficult to keep my eyes and lustful thoughts off of Cary.She always tanned when it was just us and she enjoyed getting me worked up and hard and did it mostly my favorite way,by having me rub suntan oil on her and she loved how hard I got while rubbing the oil onto her back side,which included her legs and her perfect bubble butt.I got so horny and hard when straddling her and bumping my cock into her ass,back and legs.On this particular day,she convinced me to tan with her and said she'd rub oil on me which made me even harder.She offered to do my front as well as my back and who was I to argue about it.?
She was very thourough and told me to take off the speedo and she would go nude as well.Oh hell yes,I'd love to have my hard cock out and throbbing hard in front of her and I would be treated to her perfect breasts and bald pussy.She said she really wanted to rub oil on my big hard cock so it wouldn't burn and I agreed and said I'd return the favor by doing her boobs and pussy and she liked that idea.So we took off our suits and I grabbed the oil and poured it all over her and began massaging it into herbreasts and her nipples were like little bullets and as I straddled her,my cock was hard and twitching and while I focused on her nipples,the head of my cock was poking between her ass cheeks and as I scooted downward,it drug over her pussy which made us both even more aroused.
She said I needed to work the oil onto her beautiful bald pussy too.I told her to flip onto her belly because I really wanted to massage her perfect ass and I could also include massaging her pussy from behind also.
She was moaning and breathing heavily and I had pre cum leaking and dripping on her from her back,ass and legs.She reached back and grabbed my cock and said it was her turn to massage oil onto me.I sat down then reclined on one of the lounges and watched in awe as she poured oil on my throbbing cock and she started slowly stroking it from my balls up to the head and did a better job than I ever did.She payed close attention to the head as she was stroking more pre cum out on every upward stroke.It felt so good and the feeling of building up to an epic cumblast wasincreasing quickly.
The squishy sounds and watching her boobs jiggle while she moaned each time she stroked up and made more pre cum flow out,also she squirmed her exquisite ass and pussy frantic like,while she was building towards her climax.We made eye contact and leaned in and tongue kissed each other with passion,which this kiss was long and we moaned into each others mouth as we both edged closer to orgasm.The kiss took us both over the edge and I said oh shit,I'm cumming and she just was able to state the same and then boom,my cum exploded,shooting three and four feet up and out,rope after rope,each blast feeling pleasure increase and she exploded into an orgasm that made her scream out as my cum was spraying onto her face and tits and it was at least 8 strong ropes that flew out and she kept stroking and I was not sensitive at all and could tell that there was more cum building already.
I told her oh shit,don't stop,there's still more to cum so she squeezed and stroked fast and firmly and I said oh my God,get ready and she moaned loudly and started cumming again and I inserted two fingers into her flooding pussy and she clamped down on my fingers then as she contracted rhythmicly on me,I exploded with another 5-6 big ropes which made her orgasm increase in intensity and we both were twitching and quaking with cum all over us.I felt like almost blacking out and fell back into the lounge as she fell onto me and we both were catching our breath,amazed at how good that was.The fact that it was my gorgeous little sister,made it so intense and she said the same thing.I said let's make some lunch then I would love to tongue massage her from head to toe and then wanted to fuck her for a couple more hours to see how intense that will be.I told her I loved her and said it too and so we ate then had incredible sex for the next two hours.She actually told a couple of her sexy friends and her and her friends want to have a "tanning"day soon and want me to massage suntan oil onto all of them.I must be in a sort of heaven and can't wait for that day to get here.
