It happened 3 years ago, i was 17, our parents died in a car crash leaving me to care for my sister. Which wasnt bad at all i suppose, she was no trouble, and being nearly 7 years younger than me she listened to me and did as i said. The only problem was that when she was scared, or upset, she would come into my bed at night and curl up in my arms.

When she was young this wasnt a problem, but as she got older, i began to find myself getting aroused at the sight of her growing tits under her nightie, and i worried that when she came into my bed that she would notice.. thankfully she never did.

One night, during a thunderstorm, i awoke to find her (no surprise) in my bed cowering next to me. What was surprising was that she was totally naked, giving me chance to look at her perfect 32B tits and bald pussy. I suddenly got this urge to fuck her and my cock started to stir.

"What are you doing?" I asked her.

"It's only you, and you don't mind do you?" she replied.

"Of course I don't" I said as i moved the covers to let her under next to me, careful not to let her see my semi errect cock. She curled herself up, arms around me and I could feel her nipples against my skin.

Now not being too good at this I never explained sex to my sis, so when she moved herself and her hand touched my swollen 9 1/2" cock, she said.

"What's that?"

I was stumped, how could i explain to this sweet innocent 13 year old that my cock was hard because i wanted to fuck her?

"Well...it's like this..." I began.

"It's about sex isn't it?" she asked calmly, i just stared blankly at her.

"We've covered this at school," she continued.

"And to be honest I've wanted to do it with you since i learned about it."

I couldn't believe my luck, my little sister wanted me as much as i wanted her. Without another word I spread her legs and rubbed her pussy. To my surprise she was already wet. She moaned as i found her clit and started to rub it. She reached out and started to pump my cock for all she was worth, the touch of her small hands was almost to much to bear and i thought i was gonna shoot my load straight away. She was bucking her hips now as she worked her way up to her first orgasm. As waves of pleasure rocked through her she let go of my cock and screamed.

A minute later when she had calmed down, she looked at me with mischievous eyes. I followed her gaze down to my cock just as she took it into her mouth and sucked. What she didnt have in skill she made up for with effort, and it wasnt long before i shot my load into her mouth. The unexpected taste of cum made her gag and spit. She lay back exhausted on my bed.

The sight of her still dripping pussy was enough to make me hard again. As I looked at her, a thought crossed my mind, I had never fucked a virgin before and i wondered if my cock would fit. "Only one way to find out" I thought as i guided my cock in.

When I reached her pussy she gasped as i managed to push the head in. She was so tight it was like a vice either side of my cock. I slid my cock in a few more inches.

"You sure you want me to?" i asked her as i reached her hymen

"Please.." she gasped. "Give me all you got, I want you bad."

Talking this as an ok, i rammed in as hard as i could making her scream in pain. Not stopping I started pumping my cock in her as fast and hard as i could. Gradually her screams of pain turned into moans of pleasure as she worked up to her second orgasm that night. I knew I wouldnt last long in her tight pussy but when she came, her muscled clenched so tight i shot my load on the stop, yelling in ecstacy at the top of my voice.

The next day, and the day after that, in fact every night since, me and her fucked snd when she was 17, she got pregnant,...

but thatz another story.
