Bikini Line

Two or Three weeks ago my sister (T) who’s 17 got a few deliveries from Amazon. She had told my mom and dad that she had ordered some bathing suits for our upcoming Spring Break/Easter Family Vacation.
I’m 19 months older than my sister and I’m in my freshman year of college.
My sister and I have always been really close to one another growing up, not like the typical Brother and Sister where there’s a lot of arguing and fighting. We’re just normal, or I thought we were until this past weekend.
My sister is really pretty and has an amazing body but she’s not super intelligent and I don’t think she realizes the effect she has on boys.
It was this past Saturday afternoon that everything became very complicated.
My sister had opened her packages to try on her new bikinis.
Our Mom and Dad were out running errands and getting stuff for our trip to the DR!
My sister has never asked my opinion on any of her outfits, but when it came to her bikinis, I guess she wanted to know what a guy would think and if she was looking hot or not.
I’m sitting on her bed and she would exit our shared bathroom with a different bikini and I would give her my opinion.
This one time she came out with a bikini that had an amazing high cut and such little coverage that most of her pubic hair was showing or coming out the sides. I don’t think T was aware of it so I made mention of it. She immediately got embarrassed and upset with me. She said she does not maintain her privates during the Winter and she had completely forgotten to make an appointment for a waxing.
I told her it was not a big deal and she could just shave down there like I do. She looked shocked, and asked me if I really shaved down there.
I told her absolutely I do, as well as many other men. She said aren’t you afraid of cutting yourself and I told her I’ve been doing it for years and never any issues.
I said to her I don’t use a straight razor, I use my electric razor that has protection from nicks and cuts but shaves super close.
T asked me if I could show her how to use it and if she could borrow it. I said sure. I hand it to her and show her pretty much what to do. She’s looking at it like it’s some foreign object and really has no clue what to do.
T said to me she will not be able to see what she is shaving because she won’t be able to see between her legs.
I told her I could guide her if that would help and she just said, why can’t you just do it for me real quick. I was taken back by her directness!
I said I guess I could if you don’t have an issue me seeing you with out your bottoms on. T said are you serious, how many times have you looked at me naked in the shower, you don’t think I saw you peeking all those years. She had a point there.
I tell her to grab a towel and put it in her bed and to lay down. She untied the bikini bottom and removed it. I tell her to pull her legs towards her chest and to part them slightly.
I can’t believe I’m now staring at my 17 year old sister’s pussy and my cock is throbbing in my sweatpants and very noticeable.
I began to shave her pubic area making sure to get her bikini line. T was just lying there like this was no big deal at all. She asks me as I’m doing her sides if it would be easier just to go fully bald?
I said to T, that’s your decision. She said, why not, let’s go completely bald.
Now my cock is dying to be released and I know for sure there is precum because I can feel and see it.
I continue to shave her completely. I told T she would have to get on her hands n knees so I can shave her backside by her ass.
T pops up like it’s no big deal and says to me, you should have just asked me to get in the doggie position & smiles. But then, what I was absolutely dreading. T can’t help but notice my huge erection.
She asks me if I’m okay. I tell her I’m fine. She said you don’t look fine. She told me to remove my sweatpants and boxers so I don’t get them more wet.
I’m at a point as to not giving a fuck if she sees me naked or not.
I said fine, I jumped off the bed and took everything off. My cock is at full attention now and a bit of precum was still in the tip.
T is staring at my cock and said wow Jay, you are really big.
T had removed the top of her bikini because she said she did not want any hair to come in contact with it if she decides to return it. My sister is now in the doggie position and I’m shaving her ass and pussy area and to my surprise, T has wetnesses dripping down the folds of her pussy.
I mentioned to her that I think she may be enjoying this a bit more than she should be and she said she was and when she saw my hard cock, that’s when her pussy started to get really wet.
I told T that I was almost done with the shaving and she could rinse off any excess hair in the shower.
T said that we were both so close to cuming we should just finish doing what we were doing.
T inserts 2 fingers into her pussy and is using my trimmer as a vibrator for her clit.
I’m now rubbing my throbbing cock and precum is very visible at the tip.
T reached over with her wet fingers and dipped her fingers in my precum and put both fingers in her mouth. That sends me completely out of my mind, and I immediately dive between her legs and suck and lick her shaved pussy until she is so wet and cums in my mouth. I tired to make her cum again but she had pushed me away saying it was way to sensitive right now.
T lowered herself to the floor and was kneeling in front of me. She asked if I would like to cum in her mouth? I’m like fucking ya I do.
She slowly puts my cock into her mouth and within seconds, I’m telling her it’s about to happen.
T just keeps sucking and then it happens.
I begin to drop my load down T’s throat. I keep coming and coming and my sister is swallowing and swallowing my entire load. I must have cum at least 12-14 squirts but you would have never guessed that because T did not miss even 1 drop of my cum. I was totally impressed knowing I had a 10-15 day supply of sperm inside of me.
She asked if I felt better and I said OMG yes how about you. She said she has been fantasizing about this sine she was 13, but was too scared to say anything, so she would just hide under my bed and watch me jerkoff all those nights. T said she had tasted my cum when she was about 14. She said she would see me jerkoff in a facecloth and take it from the hamper and like up all the cum. Turns out my sister had this planned all along. We go on vacation 4/18 and my sister told me I can not jerkoff from today until we go away, because she wants to swallow my entire load after waiting 22 days. I told her I would do what she has asked, but she as well can not have an orgasam as well until we go away.
She said for me to pack condoms. OMG what are we getting ourselves into!
