We,d been to a 50th me,mum and my step dad and it was quiet late by the time we got home and after a glass or two of wine mum called it a night as she was up early in the morning with me having another glass or two before heading up to my room with a refill as i sent and answered a few texts and had a wee gossip with friends as i got undressed putting my night shirt on that by the time i finished talking my glass was empty and all the wine had left me thirsty so i headed downstairs to get some juice before i called it a night and could hear the muffled sounds of the television but never expected to walk in on my step dad laying on the sofa watching porn with his cock in his hand.Instead of saying anything i just stood their watching him stroking his cock as my eyes flicked between him and the television as i saw some women being kissed and caressed by two black guys who were leading her into the kitchen while her fella was fast asleep on a chair and as i looked at my step dad i could see his cock standing hard and erect clearly enjoying the porn as he stroked his erection unaware i was their or that i was watching as this woman was now being told to hitch her skirt up by one of the black guys that saw her showing her stockings as the guy said nice now i want to see the colour of your knickers you hot horny naughty sexy bitch as he laid her on the table standing in between her parted legs taking a firm grip of her white lace panties ripping them as he yanked them off unbuttoning his own pants and taking out his massive thick black cock rubbing it against this girls pussy that as i watched i felt my own nipples getting hard and erect as i began touching and caressing myself as i could see my step dad was not only stroking his cock but was now also having a slow wank that as i watched him playing with his rock hard tool i found myself getting really aroused and remember thinking that his cock must be at least nine maybe ten inches that now saw me playing with my tits looking up in time to see this women having this guys big black cock rammed into her as he took her roughly burying his cock deep inside her causing her to catch her breath as he said to her that,s it you horny bitch take every inch of my big black cock cos i,m gonna fuck you and fuck you hard,but before she could answer she already had the other black guys cock in her mouth as he made her suck it pinning her hands gently above her head using his other hand to take a firm but gentle grip of her hair as you could him him saying that,s it you bitch suck my big black cock as his friend reached forward pulling open her blouse un clipping her bra exsposing her naked breasts which he now began to fondle and squeeze as he rammed his cock into her pussy fucking her harder and harder as he asked her how naughty she was adding i bet she likes it dirty he said to his friend as she nodded her head,As he started talking dirty to her i was so turned on i had my hand between my legs stroking my own pussy through my panties as i watched my step dad now playing with himself and having a slow wank that by now i wanted his cock inside me so as i made myself heard i was standing in front of him as he looked up at me with a look of surprise on his face with his cock still in his hand with me saying what would mum say as i sat astride him pulling my knickers to one side as i lowered myself down onto his tool taking his cock deep inside my pussy as he entered me that as i started to ride him i was going to fuck him until he made me cum all over his cock with me feeling his spunk filling my pussy as he had me climax.I gave my step dad little or no option other than to do what i said that saw me so excited i was cumming withen minutes that as i sat their catching my breath and my legs shaking a little he lifted me off and had me lean forward over the sofa as he now entered my pussy from behind fondling my tits as he started to fuck me that as he entered me again and again taking a firm but gentle grip of my hair as he pulled my head back saying dose that feel nice,do you like that you naughty bitch just like they were talking to the girl in the porn film and i found myself saying yes,yes,please fuck me harder i,ll do anything you want i said as my step dad pounded my pussy for the next ten or fifteen minutes before cumming all over him my juices running down my legs as i exploded kneeling their shuddering with my body tingling all over.It would not be long before my mum would be getting up and even though i,d lost track of time it was starting to get light but before i could move my step dad leaned forward and whispered in my ear have you ever been taken from behind,no,never not like that i said as i relized what he meant putting my hands behind me in a half heart,ed efforts of stopping him only to find my hands pinned behind my back as i felt his cock now easing up my back passage that as he buried every inch of his cock in me pausing for a few moments before slowly starting to fuck me with the full lenght of his cock that although a bit sore at first in a matter of minutes i was loving it excited even more as he talked dirty to me calling me a naughty bitch and a horny little slut as he fucked my arse and how he always wanted to fuck me from behind and treat me like the sexy whore as i begged him to fuck me harder and harder and treat me like the slut i was but as he was fucking my ass we heard my mum getting up and going into the bathroom bringing things to a stop but not before i felt my step dad empty himself into me,his warm spunk flowing into me as he came up my ass and telling me to get into the kitchen before mum came down that when she did she was in a hurry just grabbing her coat as she headed out the door passing me on the stairs as i made my way to my room with a glass of juice that in five or ten minutes i went into my step dads room where he watched as he had me strip completely naked before laying on the bed as he laid on top of me in between my legs pinning my hands above my head as he now started to fuck me hard and slow,licking my breasts and gently biting my hard erect nipples putting his lips to my ear as he talked naughty and dirty to me making me cum twice as he had me calling myself a slut saying he was going to use me like a sex slave all morning making me do what he wanted and we did things i,d never done before as he had me cumming several times licking me out and eating my pussy letting him watch me as he had me licking and sucking his cock that for the first time ever i felt him cumming in my mouth,his spunk hitting the back of my throat as he had me swallow every last drop,he even had me lay in front of him as he had me fingering and pleasuring myself while he watched me make myself cum and when he had me on all fours my boyfriend phoned as my step dad was fucking me from behind as he was calling me a dirty naughty slut that i,m sure my fella heard something before i hung up but he,d never thing or even suspect i was spending the morning being treated like a whore and a slut enjoying the best sex i,d ever had in my life and although my step dad said it should never happen again i,ve seduced him several times since and enjoy the excitment and the hold i have over him....watch this space!
