Chapter 3 - the birth

It was time, Nat and Nora had been ‘pregnant’ for almost 4 months now, and just giving anal to each other was no longer satisfying. Nat sat naked on there couch watching porn like she has been doing for the last few days, even that was no longer stimulating. Nat was waiting for Nora to come home. They were both going to remove there ‘implants’ as soon as she got home. Nora then walked in thought the door just as the actors had their ‘climax’. “Well it looks like you’ve done so much.” Nora joked. “Well I would go out but all your clothing is kind of tacky” Nat snapped. “Ouch some ones going through contractions.” Nora said back.	
As Nora tuned off the TV she began to remove her clothing till she was naked. Nat then stood and went in to the kitchen and pulled out a vile of clear liquid, she then went to the cabinet and pulled out a first aid kit as well as a syringe. Nora was watching what Nat was doing, “so we are going to start now, to the bed room them.” Nora said to Nat. “yep then, its fun time.” Nat smiled to Nora, as she followed Nora in to there bed room.  “So your turn first Nora.” Nora just smiled to Nat as she walked up to the wall and did a spread eagle.  Nat sat the vile and syringe done on a little table to help her sister, she  walk up to her and began to attach the chains that where hooked up to the wall. When each of the shackles where fashioned, Nat pressed a button and the chains tightened so Nora couldn’t move.
“So how did you want to get them out, deflation or contraction?” Nat asked Nora as she rubbed her boobs on to hers. “Why choose when you can have both.” Nora said back to Nat. Nat seemed to like that answer, she took Nora’s left boob in her hand a began to tease the stretched nipple. Nora was moaning in pleasure as Nat uncorked the plug. She then did the same to the other, no both plugs where open but no air would come out unless they were squeezed. Thus Nat seize one of the boobs and wring. Nat could feel the air leave the ball that was in her sisters’ boob. Nora couldn’t even groan her breath would only go in to then squeak out in little bursts. Nat giggled at her sisters’ expression and vocal groans. Nat took pleasure in her handy work, her sister’s boob; she could have twisted it so it looked like a deflated balloon animal.
Nat pulled the deflated ball out of her sister tit and dropped it on to the floor, and then she went to the other boob and began to suck the air out of the ball. Nat could see her sisters’ boob slowly fell as each breath pulled more and more air out of the ball. When there was no more air left she pulled that one out as well. Nat then looked at her sister, about a third of her boob was still keeping it shape but other than that her boob dangled down. “Well that’s not nice hopeful both of us will get our tits back to the way they were before.” Nat then walked back to the table to grab the vile that she has set down, she then pulled out 2cc of the clear liquid and shot it in to her sisters rounded ass. Nora groaned as the needle pulled out. With in moments Nora began to groan in pain “Sister you gave me the hormone, now I’m in labor, oh god it feels so weird.”
Nat just lay back on to the bed as she watched her sister give ‘birth’ to the ball. Nora would arch her body forward out from the wall then back. Nat didn’t like that Nora was in pain so she got up grabbed a few dildo’s and walked up to Nora. Nat began to suck on Nora’s cunt, Nora then began to moan in pleasure, and then Nat shoved a thin but vibrating dildo up Nora’s ass. Nora moaned super loud Nat thought she would shake the house. But that didn’t stop Nora from getting part of the ball out of her opening,  but it seemed to be stuck so Nat opened the plug to her it slightly deflate. Nat didn’t stop her advances on Nora so she then stuck a hard thick spiked dildo up with the vibrating one. Nora screeched again, as half of the ball cam spewing out. Nora then became quite as the hums of the dildo filled the air. “Nora are you okay” Nat asked. “Yeah… but I think the drug ware off. Now I have to push the rest of this out.” Nora’s eyes opened to see Nat’s looking up at her. “Nat I need to have a big orgasm, I need you to move them.” Nat knew that Nora meant the dildos so Nat thought of an idea.
Nat griped hold of the larger dildo and began to twist and pull at it, over and over till Nora began to whine again. When Nat had the rhythm she went back to Nora’s cunt, it wasn’t long till Nora began to breathe heavily, but that wasn’t going to seen Nora over the edge, Nat pickup another dildo this one was more flexible and had small spikes at the tip. She eased that one up in to Nora’s ass as it spread it wide. “AHH, AHHH!” Nora scream as the last of the ball came out along with a profuse amount of thick cum. I was so much that it made the ball look like a tennis ball in comparison. Nora was out of it, so Nat removed Nora from the wall and walked her over to the bed.

With in a few hours Nora was up, she what still sluggish but she need to repay her sister. Nora realized that Nat want in the room, so she got up and walked up to the room next door, it was Nora’s and Nat’s personal invention room. You see the two sisters didn’t like any thing store bought when it came to sex toys, they would break so easily the girls home. As soon a Nora opened the door she could see that Nat was placing a few dildos on to the Fuck Me Machine. It still wasn’t ready yet but it was still had its uses (think of South parks new travel, you know, the think that had all those cocks), Nat looked to the door to see Nora walk through. “I had and idea while I was getting you off. Since your so tried I thought I would have the machine do it but first I want you to get my tity ones out first.” Nat said as she stood full erect. 
Nora walked over to the machine and began to strap on the cuffs and casts that would hold up Nat. as soon as Nat was ready, Nora pick up a soft mallet began to hit the rine that showed, then she worked all over Nat boobs. Nat was whimpering in pain as Nora was doing this but she knew that if they were whole they could never pass thought the nipple opening. Before long light pink slots began to appear on Nat breast, but as Nora hits her sisters’ tits she sees that they are loosing their form. Then they began to sag and small trails of watermelon juices began to leak out of her sisters tits. So Nora attached her mouth to one and began to lap up all that she could. Nora could taste the juice slide down her chin and neck and over her now limb breast. As Nora pulled away she grasp a hold of one of Nat’s boobs and compressed, as she did chunks of the melon and the juice cam jetting out of her tits like spout of pink and green, Nora had to make sure that nothing was left so she pick up her hand and felt inside of Nat tit, it was warm and soft. So she went to the other one and did the same.
Nat’s eyes where no longer visible, as Nora backed up she could see how Nat looked her Boobs weren’t even recognizable any more, they looked like an open meat sack that dangled on hooks. Nora looked for the vile and the other syringe that had to be lying around. When she found it she didn’t want it to wear off like it did her so instead of 2cc she pulled out 4cc of the clear liquid. She took the syringe and plunged its contents into her sister’s ass. Nat groaned at the penetration of the needle in to her flesh, as Nora pull the needle out Nat began to wither in pain. Nat’s eyes widen I the pain of the contractions, she was trying to gather enough air to breath. With each contraction Nora smiled and knew this pain she could really help her sister through this part but she was going to give her pleasure as she gave ‘birth’. Nora moved Nat’s floating body over to the standing dildos, when her Nat’s ass at the right place then she walked over to the levers and pushed one down. 
As it hit the middle marker the long, thin, ball tipped orange dildo reached up and began to enter Nat’s Ass She screeched in pain as her hole began to stretch to accommodate the orange dildo. Soon over half of the dildo was in side Nat’s ass, Nat was howling in pain so Nora pushed the lever all the way down and the Machine worked the dildo up and done in Nat’s ass. With out much help a third of the melon was out of Nat tunnel. Nora looked to see that her sister pussy was super stretched to bout the size of a grapefruit, not only that but it was white with light green lines. Nora stepped back over to the levers and pulled the first one. The dark purple one with it was smooth but the head it was covered in small bumps, as it enters with the orange one Nora pushed it all the way down. It starts to twist, Nat then begins to moan and screech, with each contraction the melon gets forced out.	
Just in time the last of the oblong melon hits the floor and brakes, Nora rushes over to Nat as she continues to be drilled from behind only to find that her sisters is now a sleep as cum continues to drain out of the now overly stretched pussy. When she sees that Nat is okay she gets her off the Machine and caries her over to the bed that they share…..

It has been about two weeks after the ‘birthing’ Nat and Nora are still on the road to recovery, Nat and Nora’s breast have regained there shaped but they are now large insized, what were once B-cup stretched to I-cup have now become an easy E-cup. Even there tunnels have returned to normal, but they are super sensitive. Nat still works on the Machine every now and again but is more interest in getting more cocks in her. Nora is all about showing off her body to any boy or girl that passes by. She even is Nat test subject when she cant get any guy in her holes. I guess next time they have to have more guest over for some “Fun Time.”
