Today I appeared in his room in my cutest bra and panties, whining at him that I needed him to help me learn how to please a boy I really liked.

Kneeling on his bed I tugged at his shorts.

"No Sarah, they've not even left yet, what is wrong with you?"

I listened.

"They've definitely gone, I know the sound of dad's car as he pulls onto the main road. Come on, help me out. I see you look at me like your friends do.

"Don't you want to see this?"

I cheekily dragged off his shorts and before he could protest any more I stood up, unhooked my bra and let him see my perky boobs.

 "Jesus Sarah, stop it. You re going too far. You have no idea how much trouble I'd be in. You're my sister. Get dressed."

But his cock betrayed him.

I could see it flexing under his shorts and I quickly put one knee between his thighs and extracted it, surprised at the thickness as it swelled in my little hand.

 Within seconds it was in my mouth and I was doing everything I'd seen online to make it wet and hard.

Josh moaned but I seemed to have broken his resistance. I looked up at him with wide eyes and he stroked my hair.

"Christ Sis, I don't think you have anything to learn. That is so good. The fact that it's you just adds something to it. I'm going to hell for enjoying this."

I smiled as I tried to fit more of his cock into my mouth. My wet pussy ached and I knew Josh was turned on enough to go all the way if I could get his cock anywhere near my sweet cunt.

 Pulling back, I lay on the edge of the bed, legs spread and bit my lip.

"PLEEEEASE Josh. No-one will ever know. It's hardly worse than what we've been doing."

He looked conflicted, but his fat cock was nudging my slit and I was willing him inch by inch, straining my hips toward him as the tip rubbed my folds and my clit cried for it to slide past.

Words were forming on my lips to convince my brother when he leaned forward and I was suddenly stuffed with cock. It stretched me on the outside and set every nerve on fire on the inside.

Josh slid slowly in and out, looking for approval as he unknowingly took my virginity. I nodded approval as he began to pound at me, my body bouncing and sliding on the bed as I screamed for him to fuck me.

I almost lost consciousness when the orgasms hit. No-one could have prepared me for how much more intense it was than the ones my fingers provided

 My stomach spasmed, my legs shook, I lost the ability to breathe properly. I was completely and utterly at the mercy of my brother as he pulled out and asked if I would let him cum on my face.

To be honest I'd have let him do anything. I happily helped him as he groaned and his seed hit my lips, my neck, my breasts. I didn't want it to end.

 I stayed on the floor, licking my lips and trying not to let any hit the carpet.

Josh was red faced and spent, lying beside me as his cock retreated from the game.

I looked up, strings of his cum still coating my chin.

"You know mom and dad aren't getting back until late...."
