This story is entirely fictional. It involves sexual acts between a brother and his younger sister including peeing. If you’re not into that sort of thing please don’t read any further. I, in no way, condone the activities portrayed in my story. I hope you enjoy reading it. If good comments are left I will write the next chapter.

********************************

I couldn’t believe that my parents had left me, a fourteen year old boy, at home, to baby sit my little sister!
Ellie could be a brat at times but in a kind of strange way she was rather cute.

I was instructed to make sure she was showered and in bed by 9.00pm as there was school the next day.

Ellie was twelve years old. She had a pretty face and short, blonde, hair. Her eyes were blue like mine. Her boobs hadn’t really started growing yet. If she was wearing a tight tee shirt the outline could just me seen and her nipples stuck out a little bit.

She had never made me feel randy, she was my sister, after all. And that sort of thing only happens in stories, right?

Tonight she was wearing a short skirt and loose top.

I got our tea, which mum had prepared for us. All I had to do was heat it up in the microvave oven.

Ellie liked sitting on the floor with her legs crossed. I gave her food to her and sat in the chair opposite. I just happened to glance up and caught a glimpse of Ellie’s knickers. A lovely shade of light pink. They were tight and I could just make out her slit under them.

I was surprised, but the sight of her mad my dick start to react. I could feel it growing in my underpants. We finished eating and I put the plates in the kitchen.

We watched telly for a while.

At the appointed time I told her to go upstairs and shower and go to bed.

When she had gone upstairs I adjusted my pants to reposition my cock inside them. It was then I realised that I had leaked some precum into them and there was a small damp patch on my trousers. My sister must be sexier than I had thought!

After about ten minutes I was busting for a pee. The only toilet was in our one bathroom.

I went upstairs and could hear the shower running. I thought that I would be able to nip in and wee while Ellie was in the steamed up shower cubicle.

I opened the door and went in. Ellie was looking away from the toilet soaping her young, slim, body. I undid my zip and took my little willy out. I started to piss. Suddenly the shower stopped running and thye shower door opened. Ellie was standing there as naked as the day she was born. Her tits were just beginning to bud but her nipples were stiff from the jets of water she had been using. She had no hair above her slit, at least not that I could see. I suddenly realised how pretty she was.

“Neil!” she exclaimed. “What are you doing in here?”

“Sorry sis, I just had to go.”

Ellie had stepped out of the shower and was staring at my cock which started to stiffen. As I said, it wasn’t very big, but it was probably the first my sister had seen.

She walked over to me and smiled. She reached out while asking me if she could touch it. I thought how wrong this was. After all, she was my sister. But with my piss in full flow there was little I could do to stop her.

What she actually did was a surprise. She did touch my, now quite stiff, cock but she also put her little hand in my urine flow. She then put her fingers to her mouth and licked them. She had a smile on her face. She dropped to her knees and put her open mouth between my cock and the toilet pan. I had nearly emptied my bladder but what I had left she swallowed.

When I had finished she got up and smiled at me.

“I liked that” she said. “Would you like to taste my pee?”

I had never seen a cunt as young as hers, and had only seen others on the internet. Hers would be my first. How could I refuse.

She told me to lie on the floor. I obeyed. She squatted over my face.
I noticed that she had some blonde whispy hairs just above her slit.
Her pussy was close to my mouth and I stuck my tongue out and started to lick her sweet pussy. She tasted nice and clean from her shower. Her little clit grew a tiny bit as I licked.

“Are you ready?” she asked.

“Ready”, I said

She let her muscles relax and her piss started trickling out of her pee hole. I had no trouble swallowing it. But then it started to gush out. I swallowed what I could but the surplus went on the floor.

My cock was still stiff, in fact stiffer than it had ever been before.

When Ellie had finished peeing she leaned forward and started licking the end of my engorged boyhood! She then put it into her mouth and sucked it as if it were a lollypop.

I couldn’t believe this was happening, especially with my sister.

She suddenly started playing with my balls in their tight sack.

That was it. I could hold on no longer. I shot my sperm into her mouth. I felt like I was cumming more than I ever had when I jerk off.

Ellie turned sat up and turned around. She slid her body down mine so that my softening cock was near to her cunny lips.

She leant forward and put her lips on mine. Our mouths opened. My cum then dribbled from Ellie’s mouth into mine. Soon her tongue was probing mine and my cum was constantly being exchanged between us.

She said she would like me to put my dick inside her.

I was so spent that I doubted I would be stiff enough for a while so suggested we wait for the next time our parents go out for the evening.

Ellie put her nightie on and went to bed. I cleaned up the bathroom floor. Just in time! The front door opened just as I had finished.

I shouted down saying that Ellie was in bed and that I was now going to bed and would see them in the morning.
“Good night” they shouted back

I really hope they go out again soon, I thought, as then Ellie and I would be able to continue our sexual adventure.

To be continued……
