Nothing because we get interrupted...

I am frustrated by not getting my orgasm but also happy and weak from all the excitement so I don't know what to say when I finally hear Mr. Robertson in a surprised voice. "Oh Steve! You're awake?!"

I turn my head looking up and there in den semi-dark in the doorway stands Steve, in white boxershorts with a clear hard-on inside. He looks shocked and tears run down his face but he doesn't move or say anything.

Mr Robertson dabs his sweaty face with a napkin catching his breath and then he kind of shruggs at the whole scene looking at Steve's crotch then back at me still on all fours leaking cum out of my ass. He walks past Steve and pats him on the shoulder saying "Sorry son, but your sister was in **** need of some discipline", and with that he leaves the room walking upstairs.

I am too shocked to move or say anything so I just stare at Steve with wide eyes, my face red from embarrasement and exhaustion. Steve slowly starts to move towards me and I am kind of scared by his empty look.

"Steve....please....I am sorry....I still love you so much....it is just...", he shakes his head barely visible for me and I stop stuttering. As he reaches me he lifts his foot and gives me a hard kick at the hip which sends me tumbling to the floor in front of the couch. An embarrasing cum fart escapes me spraying more of Mr Robertson's cum onto my legs.

"Ouch, Steve, I am sorry!", I whimper in a panic. I try to crawl away from him towards the kitchen but instead of following me or trying to kick me again he drops his shorts and gets down on all fours like a dog, looking towards me with his head tilted slightly to the side but still with that empty expression.

"Steve, please say something!". Again that little shake of the head and a deep growl from the back of his throat. The growl sounds angry and **** and dangerous. I don't know what to do, I am so confused by his behaviour so I crawl towards the kitchen a bit further which makes him growl louder. I stop and gulp. As I kneel there on all fours Steve crawls up behind me. Moving like a dog on all fours his hard cock clearly visible dangling underneath him. He circles me as I watch him, his expression still empty but slightly manic.

As he comes up behind me again he stops and puts his face down to my feet, sniffing and licking my bare feet like a dog greating another. I freeze, feeling his warm wet tounge flicking between my toes. What is he doing? He never acted like this before. I wiggle my toes and again he growls so I stop. He sniffs up my calfs and my thighs, stopping where my legs got sprayed with cum and he starts to lick it off. He is clearly crazy, licking his father's cum from my body but it sends another pulse of blood down my semihard shaft making it stiff as a mast again.

I breathe heavily and hold still as Steves tongue works its way up towards my balls and my molested boy pussy. As he reaches it he again pushes his nose in, sniffing like a wild dog and licking around my entrance which lets me moan and shiver.

I never saw Steve this way and even though he is licking my cumsmeared asshole like a cuck he never appeared so dominant before which makes my own shaft pulsate with pleasure.

He is acting like a dog finding a bitch in heat and I am more than ready for him since his father left me all horny. I arch my back pushing my anus out into his face pawing the floor with my hand showing that I am ready.

Without a word he seems to understand my posture like a dog would and with a long lick at my asshole he starts to shove his upper body onto my back. His weight bears me down and he grabs onto my sides above the hip as he positions himself. Without grabbing for his cock he starts to make humping motions and the tip of his wet penis slams into my thighs and my balls, trying to find my hole. He grunts and humps tightening his abs to lift his hard-on up to his belly. Finally with a push forward he finds support for his thick red mushroom head between my butt cheeks and pushes against my already fucked and sore hole. With another heavy grunt and another hump he pushes in, a loud farting sound escaping my asshole as his father's cum lubricates his way in. I whimper loudly as his whole length enters me his balls touching mine. He is about the girth of his father but several centimeters longer and I can sense Steve's fat log deep in my intestine. He continues to hump me like an uncontrolled animal. Deep and regular while pushing me to the floor hard, growling into my ear, biting my shoulder and neck. I just hold still like his little bitch letting him breed me, whimpering like a puppy as he pushes me back to almost cumming onto the floor.

He can sense my body tightening up, about to cum so he shifts all his upper body weight onto my back and he lets his grip loosen. One of his hands moves down my belly and roughly grabs my cock pulling it towards my belly. He holds my wet red head tight between his thump and indexfinger while humping even harder than before.

Holding me this thight and ramming me hard he can sense my little cock starting to swell and pulsate about to release my semen. As I am about to cum he stops his growling and also whimpers softly while licking my ear which finally sends me over the edge. I shoot out long strands of white cum onto the hardwood floor as my sphincter contracts around his shaft deep within me. Steve gives me a few hard deep pushes and then I can feel his swollen cock exploding deep inside me in synchronicity with my own little boyclit. We both cum long and hard whimpering like two young dogs on the floor. Steve fills me up, his cum mixing with whats left of his fathers until he finally pulls out with a slurp making another splotch of semen on the floor behind me. Exhausted and without a word trailing a long strand of cum from the tip of his cock he crawls out of the room on all fours. I lay there in my own cum panting, fucked and happy.
