I've always been my sisters keeper. Since the day she was born Sarah was the light of my young life. I was her big brother and she always looked up to me for comfort, whether from her bottle or a diaper change or just holding her.

I was almost 9 when Sarah was born. Unfortunately the birth took our mothers life in the process. Dad had to take a second job to support the family and it left me to step up as the big brother/mom/dad role while he was working.

As Sarah got older she became more than JUST my baby sister. She became my best friend. We did everything together, from homework to playing in the pool to even talking about who we liked in school. When Sarah was 7 we had "the talk". I was just 16 but she wouldn't have wanted it from anyone else, not even dad. She had soo many questions it seemed to never end.

"So, you mean....we have different parts Danny?"

Up until this point I had never really considered the possibilities of our shared friendship and beautiful sibling relationship.

"Yes Sarah, see, you have a beautiful flower, like mommy had, and I have a peepee like daddy has" I told her She looked at me perplexed, "Daddy goes to the bathroom funny in the morning Danny, is that why he stands up, cause he has,....um...a peepe?" she giggled at the thought of the word, that our mother had taught me many years before.

"Yes Sarah and I have the same as Daddy's."

"But why are we different Danny? we soo close and special how come where different?" she asked, almost as if our genders had betrayed her a little.

"Well Sarah, because a girls flower is special, when she gets big, it makes babies, but a girls flower can't do it alone, it needs a boys peepee inside of it to make a baby with her when they love each other and make each other feel good."

"Well I love you Danny, and I feel good around you."

"But that's different Sarah, I'm your brother."

"Why does it have to be different Danny, you just said if a boy and a girl love each other the share that to please the other?"

My thought process was cut short as Sarah, my little sweet baby sister, pulled back the ruffles of her sun dress and exposed her pretty pink hello kitty panties. I felt my heart increase and my cock slowly expanding.

"Don't I make you happy Danny?" she asked.

"Of course you do baby, since the day you were born."

"Would you like my flower Danny? Not for babies, but just to feel good?"

With that she pulled her panties to the side revealing her beautiful but small slit. I had seen it a million times in my 7 years as her keeper but never once had I thought about it the way I had right now.

"I don't know Sarah, I think my peepee might be too big for you" as I pointed to my now engorged erection.

"I WANT to make you feel good Danny, the way you said mommy used to make daddy feel good before I was born."

"Can we try, Danny?" she asked.

I had already had a short term girlfriend at this point, and I knew all about the pains for a girl loosing her cherry, but for my little sister I never wanted her to be in pain.

"We have to do something first Sarah."

"Yaaay YOU DO LOVE me!" she giggled as she jumped to her feet.

I felt her soft body as I had done non sexually for many years, but this time WE were different. She smiled as I ran my hands over her soft belly.

She softly kissed my cheek and whispered in my ear "I'm not scared Danny, because I love you too."

I slipped my fingers under the band of her small pink panties and in doing so brushed my finger against her tiny clit. Sarah's knees almost buckled instantly as I caught her she looked up at me with tender eyes.

"I like that Danny, it makes my flower feel really go......" her speech was muted by shaking and convulsions in my arms. My little sister was having her first orgasm in my arms there on my bedroom floor. My cock became rock hard at the thought. I had never brought my girlfriend home for fear that Sarah would catch us. Now I was coming to the reality that I always had the girl I loved, right here this whole time, cooing in my arms post orgasm.

"That felt really good Danny, but know its your turn" She sat up and pushed me to the floor. She slid my cock through my boxers in amazement. "Its SOOO big Danny! Is daddy's peepee this big too?"

"I don't know sweetie" I replied.

"whatever" she said " he's never here anyways and I don't love him as much as I love you Danny."

She pushed her hands into my chest yo make me fall to the floor and climbed on top of me like we had wrestled and tickled each other so many times before. She pulled her panties to the side and slowly rubbed her wet slit against my shaft.

"Does that feel good Danny?"

I arched my back, "You feel wonderful baby, but its really supposed to work when its inside your flower."

Her next actions shocked me. My ex girlfriend cried out in pain when I broke her cherry. But in an instant my little sister had taken my wet shaft, placed the head in her tiny opening and sat straight down, burying my 8 1/2 inch cock to the hilt and hitting her pubic bone.

Her eyes and mouth gazed wide at what she had just did.

"Oh my god, SARAH, are you ok, I didn't mean to hurt you!" I said.

"You didn't Danny it feels good" I was perplexed as to how she felt pleasure.

"It's not AS painful as my bike seat when you showed me without training wheels Danny."

I harkened back to the day and remember when she hit a hole in the grass her bike jumped and that little banana seat caught her just right. She must have broken her hymen on that because she cried for almost twenty minutes that day.

"Does it still feel good Danny? Do you still love me?"

"Of course I do sis, I will always love you."

With that Sarah began squirming around in joy. It felt sooo good for the both of us and I could tell she was close again as she kissed me and smiled.

"Its happening again Danny" she dug her little fingernails into my stomach as she ground her mound against my base. I felt her get wetter as she started to cum. My balls were boiling and my shaft thickened with every stroke of her tight velvet hole contracted against me.

"It's happening to me too Sarah," I grunted as she smiled down to me. I held her hips tightly as I felt my cock explode inside her deep, wet walls. My cum surged through her tiny pussy, wave after wave spurting from my cock.

"It tickles funny Danny, its warm!" she giggled.

I rolled her over on her back as the last several waves of cum surged through my sister tender body. As I gently pulled back her pussy squeezed my cock until it let go with a sucking sound. She giggled as the feel of my warm cum dribbled from her reddened, swollen lips and down her little bum cheeks.

Since that day together. She has wanted "to make me feel happy" as she puts it, almost every day. Never wanting to stop until I "feel good" inside her sweet flower, and fill her with my cum. I feel we will have many many good years to come.
