Ok so here it goes, here is some background on them
My wife is about 5'5" 260 and her sister is about the same height and around 200. My bro-in-law is probably. Six foot and around 350. This is my fantasy.... One night we are all over at our house and the kids are gone. We start to talk and joke around and my wife and her sister start to kiss.
The kissing looks like it might go further until they stop and look at us, and ask do you guys want to join? Of course we say yes, so they say you have to help us get undressed, but we are swapping husband and wives. So her husband goes to my wife and I go to my sis-in-law. We all start kissing each other and slowly remove their shirts. Then we start kissing their tits since they weren't wearing any bras. Then as we are kissing their tits we slowly remove their pants only to find bare naked shaved pussies staring back at us. They kind of look at each other with a sly grin and say we had this all planned.
So we each start kissing them and pushing them down on the bed until we get to their pussies. We slowly lick from their ass to their pussy while rubbing their clit.
We continue to tongue fuck both holes until they tell us both to fuck their asses. We commence to put our dicks in. With my sil being able to take me all at once, but my wife is having a hard time with my bil bbc. Finally she gets it in and we are pounding both of them hard my wife is screaming in pain and agony, but enjoying. My sil is loving every minute of it and telling me harder fuck my ass harder. Finally we both say were are going to cum and they tell us to pull out and cum on their faces. So we go up and pull our cocks until we cum all over their faces.
They tell us to sit back and enjoy the show. We then sit on the couch, and they commence to licking the cum off each others face. Then my wife starts sucking on her sisters tits and fingering her pussy while my sister keeps telling her to do a 69. Finally my wife goes around so they are doing a 69. They are tongue and finger fucking each other until they both say they are going to cum. They both breath heavy sighs and roll off each other.
They both say ok we are warmed up for dp, and my wife volunteers to go first. So my bil lays down on the bed and my wife eases herself down on his bbc. Once he's in I slowly put my dick in her ass. She tells my bil be gentle and dont fuck me to hard, but doesnt tell me anything. So i commence to fuck her hard until she screams to stop, but i say no bitch y iIm going to fuck you until you cry so that turns my bil on and her starts fucking her so hard shes crying. Finally i feel my bil cock pulsing as he shots his seed in her, and I then shot my load deep in her ass.
Its now my sil's turn. So my bil lays down and she jumps up on his bbc since shes use to it and tells me to ram my dick into her ass hard. So after shes situated on my bil i wind up and stick my cock in her so hard she actually screams. We then begin to fuck her as hard as we can even shes screaming in pain even though shes use to her husband bbc. Finally we I say I'm cumming and her husband is to. Once we both cum she gets off of us.
Once she gets off, she says, "I bet you guys could us a rest do you want another show?" Of course we say yes, so she gets out our foot long strap on. She has my wife strap it on while she bends over in front of me and starts to suck my cock and stroke her husbands. My wife starts to fuck her so hard my cock is going all the way down her throat. She is fucking my dick harder with her mouth while stroking her husband. Finally she lets out a scream and starts sucking hard on my dick and pulls her hubby's until he cums.
My wife is next so she bends over in front of my bil and starts to suck his bbc while stroking mine. My sil is really fucking my wife's tight hole. My wife is gagging on my cock and loving it. Finally my wife sucks me so hard i cum again and a load of cum shoots from bil cock
After my wife's last fucking we decide thats enough for tonight, but we decide to schedule this for at least once if not twice a month if we can.
Hope you enjoyed.
