i'm 18 years old and 5'9 with a 9 inch dick

it's a cold, late winter night and i've just finished work at the local railway station, where i'm employed as a porter and as i walk off the platform into the ticket office i see this grest ass in a pair of jeans,

i have a little chuckle to myself as i do a double take as i realise it's my older sister jen she see's me and calls out to me and says i've come to give you a lift to my house as the weather's too bad for you to go home, she has 36dd tits never wears a bra and is 5'6 long blonde hairand 8 years older than me

she walks over and says john has got to stay in germany for a couplre more weeks ,when we are driving home we talk and i keep glancing at her breasts and i notice that the cold has made her nipples hard which starts to turn me on 25 minutes later we arrive at her house, and lucy and kelly great me with big hugs and their mum says come on girls off to  bed with you and they go to bed.

we stay downstairs and watch tv for a while, and she got some beers for us and after a few drinks we started too talk after about 1/2 hour she asked me about girls and what i'd been up to lately the beers had loosened my tongue a bit and i was sounding really pissed off so i said good night and went to the spare bedroom and she said good night and gave me a hug with those beautiful breasts pressing against me.

i got into bed and tried to go to sleep but i couldn't take my mind off my sisters breasts and i started to wank my dick and i pushed the bedclothes off for a really good cum when i feel a waft of air across my body i open my eyes too see my sister standing in the doorway.

i stammer out appologies and cover up my dick but she says it's ok she walks over to the bed she is wearing a flannel robe over a t-shirt one side of the robe is open and i can see  one of her nipples sticking out through the fabric of the t-shirt

she sit's down on the edge of the bed and says everybody needs some sort of release let's see what your trying to release and then she pulls the bedclothes, back and looks at my dick and she says wow bro this is the biggest dick i have ever seen even john is only 7 inches my baby brother is all grown up i think i can help if you'll let me and then she takes hold of my dick and says just lay back and relax.

she starts to wank me after felling my own hand for some time her knowing movements make me moan my approval i reach out and start too gfondle her breasts through the thin fabric of the t-shirt and start too tweak her nipple and then she starts moaning her approval and she starts wanking me faster and says sorry bro but i've got to suck this and then she lowers her lips onto the tip of my dick and licks it with her tongue which drives me wild she then starts to suck my dick slowly at first and then a little faster.she stops sucking my dick  long eniough to take her robe off i notice that the t-shirt has ridden a bit higher up and i realise she's not wearing any knickers.

i start to put my fingers into her pussy and she lets out a moan but her sucking is the greatest and i can't hold back any longer and i scream out i'mmmm cummminggg and she swallows every drop and says nicely done bro and i say you too sis.

she then says would you like to see mty breats now as your always staring at them and she then takes off the t-shirt and the breasts are there right in front of me just as full amnd rounded that i had imagined with just  a slight sag from two kid suckling on them  and with that i start to kiss her breasts then while i am sucking one nipple i am tweaking the other one which makes her moan out in pleasure.

she then straddles me and my now erect again dick starts to penetrate her pussy and she says easy bro remamber this is the biggest one i've ever had so be gentle, and i start to push into her gently making both of us grunt in satisfaction and i say god sis you are really tight i didn't think you'ld be this tight especially after two kids.

she screams out in plaesure as she starts to come just as i push the last two inches into her great juicy pussy and we both yell out that we were cummimmmngggg after that i drift off to sleeps i wake up in the morning and go down to breakfast the kids are outside playing in the snow.

she walks over to me gives me a big kiss on the lips and says if you don't get a girlfriend and even if you do save some of that loving for me.

a couple of months later i overhear my sister telling john that she is pregnant and he is overjoyed later on when john has gone down the pub with his mates she tells me that she is pregnant with my kid i say what are you going to do and she says i'm having the kid and i say ok if thats what you want

7 months later she gave birth to two beautiful little boys and she is overjoyed that her little brother is the dad.
