Sliding my way down his body I knelt between his thighs. Looking him in the eyes I unclasped my bikini top, my breasts falling out onto my hands as I playfully flicked my nipples. Bending over, I rubbed my breasts over his hard cock. Pushing it back against his stomach I rubbed my full tits over the underside of his cock. Settling back I grabbed his cock in my right hand. It was the first time I had ever really looked at my little brother’s cock close up. I’d caught him running from the bathroom naked to his room a few times over the years but had never really seen him like this; massively hard and throbbing in my hand. I looked him straight in the eye as I dropped my mouth around the head of his mouth and slide my lips all the way down the shaft. He groaned and fell back onto the bed his eyes closed. I gripped him tight around the shaft my palms resting on his balls as I dragged my lips, pulled tight, all the way up his cock, stopping as my lips caught on the rim of his throbbing cockhead. Letting my tongue slide into his cockhole, I swallowed the precum oozing out my cheeks squeezing around his cock before sliding my mouth all the way down again. I continued my long slow strokes, my tongue grazing the underside of his cock, pressing against his throbbing vein. I loved the way he filled up my mouth, his cock so thick stretching my lips tight over his skin.
“Oh fuck, sis, I can’t believe my fuckin cock is in your mouth. Oh my God, my sister is sucking me off. ” His words spurred me on as I began a different rhythm of five long strokes and five short sucks on the head of his cock, stroking his shaft with my hands, pumping the cum from his balls. His orgasm built quickly, feeling his balls tighten, I pulled my mouth off him, letting him calm down. He whimpered softly, wanting to release his load, making me smile. The power I felt over him was incredible. The interplay between sex and love and the absolute taboo of the situation making me want nothing but sexual satisfaction. Jacking his cock with my hand I dropped my mouth down to his balls. Sucking one into my mouth I rolled it around with my tongue making him gasp before sliding my mouth around his second ball, rolling them over each other in my mouth. Dropping them from my mouth I slipped my mouth back over his cock. Dripping my saliva all over him making his cock wet mixed with his precum.
The sounds filling the air were delicious. His moans and my lips sucking his wet hard dick. Needing more than the occasional drop of precum, I knew that feeling him shoot his cum onto my mouth and lips would be the ultimate fantasy.
Turning towards him I asked, ” Tell me baby, do you want to cum?”
Between moans he managed to say, “God, yes, make me cum. I want my big sister to make me cum.”
“Ok baby, but only if you do exactly as I tell you, ok?”
“Anything you want, sis, anything. Just let me cum. Please.”
Grabbing his arms I pulled him up onto his knees. I laid down resting on my elbows and then slid my mouth up and down his cock once, testing for height.
