"Alright, both of you have gotten off now, so that means it's my turn. Clara, I want you driving. And I want it hard. Sarah, my love, you're all dirty. I'm gonna help you get clean." Mia is walking sex right now telling them both what she wants and how she wants it.
Mia lays on her back with her ass at the end of the bed. Sarah perches her pussy over Mia's waiting face and Mia pulls her down and starts using her tongue to scoop all of your cum out of her. Clara starts wiggling your huge cock backby shaking her hips.
"Holy fuck, this thing is huge. Just remember Mia, your the one that said you wanted it hard."
"Mhmmhhhmmm." Comes the answer from Mia still deep in Sarah's pussy. Sarah is facing back at Clara so that she can watch Mia's pussy get destroyed. Clara lines it up and thrusts half way in on the first push.
"Umph," a mixture of joy and pain from being filled so swiftly from Mia. Mia's pussy isn't a tight as Sarah's was, but it's still amazingly wet and warm. You still have a huge puddle of your own cum all over your chest and stomach from cuming with Sarah. You're just going to add the next load from Mia and then the next from Clara to it.
"Oh, you like our brother's cock don't you? You love that our little brother's cock is going nice and deep. Let me all the way in." Sarah is so dirty, it's great. She holds Mia's ankles over her shoulders and plows the other half of your cock onto her. She doesn't waste any time with letting Mia get used to the length or girth that's filling her up and instead begins to jackhammer deep inside of her.
You can feel your balls bouncing off your sister's ass with each thrust. Clara pulls back about three inches and slams home again. She's going so fast that your breathing is having troubles keeping up. Sarah is pinching Mia's nipples hard.
Mia starts cuming. You can see and feel her juices push out each time Clara bottoms out in her pussy. You can feel the head of your cock slip into her womb as your slammed balls deep inside of your sister.
"Yeah, cum for your brother. Cum all over his cock. But his cock isn't stopping for you. I'm going to keep fucking you with his cock until you're dry and out of cum. That's right, keep cuming. I need more lube so that this monster can keep destroying that little pussy of yours. By the time I'm done your brother will be the only one capable of filling out satisfying you," Clara's words and thrusts and building you rapidly, but you control the urge to cum.
You want to see how much Mia can cum before you finish in her. Clara is still thrusting as hard as she can. The bed, Mia, and Sarah are all lunging back and forth. Sarah teaches down and uses Mia's cum and starts rubbing Mia's clit fast.
Immediately Mia's orgasm goes to next level. Her pussy goes from milking your cock to almost involuntarily trying to rid herself of your massive dick. The orgasm and constant pounding are to much for her to deal with. Clara thrusts one more deep time lodging the head of your dick deep inside of Mia's womb. You begin to fill it.
Wave after wave of white, hot, sticky cum fills her baby cradle to over filling. Cum starts to leak out of her womb down your shaft coating the entire inside of her pussy making your sister a one of yours. One more to mark and all the of the girls in the next room belong to you.
There was even more cum shot into Mia than Sarah. Your cock attached to you has shot cum up onto your neck and given you a pearl necklace. Your pecks are coated. Your belly button is like a damned lake of thick cum. Fuck your sister is amazing.
