When Leah (my little sister) was a baby her dad left and our mum was always at work and it was left to me as the oldest brother to look after her, now she is 8 with light blond hair and stunning body. She does not leave me alone, so every weekend I go swimming with some friends to get away and every weekend she tries to convince me to let her come. I would have let her but she can not swim and I don't want to spend the weekend teaching her how to swim.

Before I start I should introduce myself I'm Jack I'm 17 and I live at home with my 2 sisters and one brother and my mum better not forget her, and I'm pretty typical male very athletic, I would say I'm average in size, that's enough about me.

Today is Saturday, 10am and I'm on my computer when my mum walks in and tries to convince me to bring Leah swimming with me today.

First she said nicely "Hello Jack", as soon as that was said I knew she wanted something "would you be able to take your sister swimming with you today".

"But mum its the only time I get away from her," I said while shaking my head.

"She really wants to go with you and if you take her I will get you that game for your computer and I will give you a lift to the swimming pool" she said with a smug grin on her.

"OK go on then but I want that game today."

"Thank you hun."

She walks off and I see Leah with her ready made bag run down stairs, she knew I was going to let her. I get my bag packed, then at twelve my mum drops me off at the swimming pool.

We arrive at the swimming pool Leah jumps out the car wearing a pink jumper with pink skirt with white and pink leggings(She likes to match), I get out of the car and see my friends at the entrance. I say goodbye to my mum and start to walking towards them. Leah running happily around them while I talk to Sam and Jordan.

Sam smiled "Hey Jack, your little sister coming swimming today."

"Yes Sam, mum made me bring her so we got to keep and eye on her she can not swim."

A little voice from between us said "I can swim."

"OK sis."

Sam said "Sorry Jack but I want to go in the deep end."

"Me too," Jordan added.

"OK well I'm going to have to stay in the shallow end with her."

We walk in and hear a voice from behind the counter "Next please."

We pay and go inside. We go down stairs and into the male changing room with Sam and Jordan. There are only small stalls with no doors and can see over them so you don't get much privacy. I chose the corner one because there was a little more privacy.

We start getting undressed. I feel uneasy getting undressed in such a small area with my sister standing so close to me, I would have let her have her own stall but old guys were getting out of the pool and getting changed so I thought it would be better if she stayed with me.

As I take my boxer shorts off I check to make sure Leah is not looking and she was not, she had already striped and standing there naked and looking in her bag for her one-piece. While I take my boxer shorts off I notice a guy walk past having a gaze at her slender body and her starting to form breasts with there lovely puffy nipples. I stop and stand there naked looking mesmerised at my little sisters body as she tries to get her one-piece on, her small tight pussy just out of my sight, then I remember the guy looking at her and he will have the perfect view. As quick as I can I move Leah further in so she is out of his view. As I move her my penis strokes her cheek and the tip just enters her open mouth then pushes the inside of her cheek then pops back out, I was not sure what happened as I was making sure the guy moved away.

After he moved It just hit me what happened after looking down at my penis and seeing the wet tip I looked at Leah to see what effect it had on her she didn't look bothered and just concentrated on getting her one-piece on. I quickly get my swimming shorts and then get a locker and put my bag in then go back to Leah to see if she had finished.

"What are you doing Leah, you have put it on backwards, come here."

"Sorry I didn't know" she said with a frown on her face.

"Don't worry sis" I said happily because I get my chance to see her tight pussy.

I got on my knees and took it off her, when I pull it down her sweet tight pussy is revealed , as soon as I see it I can feel throbbing under my shorts and start noticing parts of her in a different way her body so soft and slender, her pussy so beautiful tight and just amazing. I turn it around and put it back on her going as slow as I could while pulling it up making sure my finger is in the right place so I can have a quick touch of her pussy lips while I pull up, the touch..... WOW so soft and felt her little clit berried deep inside her lips hidden away as soon as I touched it I heard Sam and Jordan.

"Were is Jack," Jordan said.

"Over here I think."

As soon as I herd that I quickly got my mind back and pulled the one-piece up and put her arms in when it was fully pulled up you could see her pussy show through her one-piece it had sucked it in you really could not miss it, I was tuned on but also nervous other people are going to see this.

"Jack you finished."

"Yes I'm coming now" then I whispered to Leah "You need to quickly come with me and get in the pool."

After quickly getting her bag and putting it in the locker I grabbed her hand and lead her to the pool, it was quite empty today I got in then lowered Leah into the pool. I don't know why Sam and Jordan waited for me because as soon as we got in the pool they left me to go to the deep end.

I got a few chuckles out of watching Leah trying to swim but not being able to so after a few minuets I did the basic holding her stomach while she swims making sure to rub her soft nipples every now and again. After a while she got bored so placed her on my stomach and started swimming backwards she slid down and every stroke I did I could feel her small sexy ass rub my penis and then when the stroke finished and I slowed down she went forward and stroked it a little more using her tight pussy I could feel my penis throbbing and starting to get hard I couldn't help myself I went as fast as I could making the feeling of her rubbing my penis more vigorous. Then my arms started aching. I had to stop my penis was so hard it started hurting.

I started thinking back I have had my penis in her mouth and my finger sliding over her pussy and she didn't complain or say anything would I be able to get away with another little feel. I started by going to a quite part of the pool then sitting her on my stomach how we had been before, she slid down again and was on top of my penis. After having a quick look around I moved my hand up her soft legs and got to her tight pussy. I started just stroking it pushing my finger in the middle feeling the lips pushing on my finger, I looked up she was sat there with a smile on her face and her hands near her mouth, I try look at my hand under the water moving it under her suit and into the gap of her lips, feeling the wet and soft clit, just remembering how it felt when It was dry, we had been in the water for a while and the feeling in my fingers was not as good, I open my eyes look around and we had seemed to get some attention off the life guard and a man who had two young children they looked older than Leah but still quite young around 11 or 12 he seemed to give me a smile as if he knew what I was doing. Getting a little nervous I stopped and then removed my fingers from in between her slit.

We only had 20 minuets left so I told Sam and Jordan we was going to get in the showers for a bit they said they were going to stay in a bit longer. We got out of the pool me trying to hide my boner from everyone as we got out.

We walked to the shower I started washing myself and Leah was washing herself. I looked down at her washing her small body, her nipples poking though the one-piece and her pussy still easy to see though it. I couldn't't help myself I bent down and smiled at her, slowly moving my hand to her nipples feeling the hard things poking out from her one-piece then going down to open her pussy lips again feeling them pushing against my fingers, started searching for her little hard clit. As soon as I found it I had to stop she was starting to moan and I was rock hard.

A few minuets later the man walked past with his two children, as he walked past I had a good look at his kids one had short dark brown hair with a slim body and her breasts that were developing was a lot bigger than Leah, the other had long blond hair like Leah with the nice slim body, her breasts bigger than the other and she looked to be older of the two, as they walked past they had big grins on there face and the man looked pleased with himself.

I though it was time to get out and dressed I got our bags and got our towels out I quickly got out of my shorts and put the towel around my waist so I could help Leah out of her one-piece, when she is out I get strait to it, I push my finger between her soft tight lips stroking her, she lets out a little moan, her eyes shut her mouth open, I push my finger in her pussy at first it was impossible to push it in after a few attempts the first little bit of my finger entered after that the rest slid in almost like it was being pulled in, then she let out a louder moan, my finger slowly moving in and out, already there was juice dripping down my fingers, her legs starting to shake her pussy tightening around my fingers.

I pulled it out and had a taste, so lovely a taste that was better than I could Imagine. I stand up and take off my towel get my penis and put it close to her mouth. Leah looks at me for a second with a confused look on her face and then looks at my penis inches away from her face.

"All you have to do is open your mouth Leah, I will do most of the work, just need to suck on it" I said as comforting as I could.

She nodded and opened her mouth then I pushed it inside her mouth having her warm wet small mouth rapping around my tip I had shot a little amount of cum inside her mouth almost instantly then I pushed to see how much she could hold in her mouth after all the tip disappeared in her mouth I pushed a little more in and she started to gag I pulled out to make sure she was OK she really did not like the feeling of gagging on my penis, but to my surprise she opened her mouth again ready for me. I pushed it in again, this time her tongue started moving around licking my tip so delicately within minuets I was about to cum.

"Leah" I said, she looks up at me, "A little bit of juice is going to come out and you need to drink it all up", she nodded I pulled it out a little making sure a piece of the tip was still in, her tongue still licking the little part of my penis that was still in, my hole body tenses as I shoot my load inside her mouth then I relax, she tries swallowing but starts to choke on it, she starts coughing which made my cum spray out of her mouth when she had stopped coughing, it was dripping out of her mouth over her small breast on her puffy nipples dripping all the way down to her pussy, I kneel down and ask.

"How was it."

"Horrible what was that."

"It was my cum, a lovely piece of me." I wipe it off around her mouth and from her breasts. "Will you have this bit for me please?"

"OK for you Jack," she opens her mouth and sucks all the cum of my fingers. While she sucks my fingers I start rubbing her pussy with my penis.

Then I hear a soft little moan coming from the other side of the room ........
