Holiday house

Note : This story is completely fictional!

My parents died a while ago in a car accident so there was just me and my sister who is a lesbian. We went to my parent holiday house 1 weekend with my girlfriend for my birthday.

"Whats in the black bag" I asked my girlfriend julie "cant say" why not?" "its your birthday present" "can I have a clue" I asked "I dont see why not it concists of your favorite 2 colours black and red and you'll know when your getting it" 

I sat down after tea watching the footy on the box my sister and julie talking quietly when all of a sudden they started yelling so I went to see what was going on "whats up" I asked "never mind" my sister Jodie told me and went into her room slaming the door behind her. " What just happened" I enquired "nothing for You to worry about just go get a shower so the fun can begin" " Ok but first I'll see if Jodie is ok" 

I knocked on her door "come in" I walked in to her room shes not a bad sort really 5'6" Long blond hair 36 b breast "look I dont want to get into it just coming to see if your ok" "yeah fine I'll live and yes just stay out of it" 

I went for my shower which was good when I got out I heard some giggling and thought to myself well everything must be fine now. when I walked out the place was deserted walked into my room and on the bed was Julie wearing a black lacey bra and g-string panties and a red garter and what looked like a red velvet bag with eyes cut out and a mouth, she was tied to the bed must've been my sisters help on her stomach was a note
: I will not say a word so no questions and anything goes.

I slowly ran my tongue up her body and gave her a kiss on the mouth and thanked her for my present pulled down ger panties " wow you shaved for the occassion" I sunk between her legs and sucked on her juicy lips for a while after shed orgasmed I then moved to her mouth "my turn" i said as I stuck my 10 incher in ger mouth I say she had improved since the last BJ shed given me. I decided now was the time and positioned myself between her legs rubbed my cock up and down her slit before inserting it in "gee whets going on here you seem tighter than the last time" no sooner had the words escaped my lips when a laugh came from behind " you Checky bitches " I once told my girl how I used to fantasize about sex with my sister before I was with her now it seems she told her as I was buried to the hilt in my sister with my girl not unmasking my sister and sitting on her face 

" well you see I had a lesbian fantasy and when you were an that business trip last week I decided to live it out with Jodies help anyhow we were telling secrets so I told her yours and we cooked this up including that argument and the rest you know" "wow man" this is the best present a guy could ever have "Ohh man I'm gunna cum" "dont you dare pull out Jodie wants a baby and our going to help" no argument here I thought as I blew my load " one more favor" "no worries remember anything goes" "get off my sister on to all fours and sis Julies going to eat you out while I fuck her ass

So all our fantasys lived out in one night of incest and lust, nine months later I was a dad twice to my now fiance and my sister and as they say the rest is history
