Chapter 2 - the pregnet sex

It had been only a few week since Nat and Nora’s ‘Insemination’. Nat’s Watermelons were growing fast and Nora’s little beach balls were ‘growing’ as well. It was early in the morning when Nat woke to find that vine to the watermelons had shriveled and broken off. As Nat sat up her ‘new’ Boobs were heavy and stiff. Nat lift one up to look at it carefully she could see that it had rounded it perfectly she could even see some of the watermelon still poking though the opening of her nipple. Nat then lifted both of them in her hands and began to move them around in her hands. The skin was soft and her nipple super sensitive.
“Ah!” Nat groaned in pleasure at the super sensitivity of her nipples. Nat then took one of her fingers and taped the rine that was showing. The sound ripping through the watermelon, Nat moaned in sensation. “I wonder how my ‘child’ is coming along.” As Nat moved her boobs to the side of her like swinging appendages. Nat could see that her hips have widened and her stomach and lower body was expanded. Just like she would have been if she was really 9 months pregnant. Nat knew that her twin must look just like her and feeling just the same. Nat slid from the table that she had been confined to for the last 2 months, her legs felt like weak and shook with every step. She then stood erect with both of her breast still off to the side to see that her stomach had stretched out, and a small vine still attached to the one in side Nat’s tunnel.
Nat looked up thought the door to see the house had all of the lights on, so Nat broke off the vine and began to walk up to the hours. As she opened the door she could see her sister in the refrigerator with her naked ass up in the air. “Well isn’t that a wonderful sight” Nat said. As Nora turned to see her sister leaning in the door way, with her large breast resting against her crossed arms. Nora smirked and looked her sister over. “Love the tit’s sis.” Nora said as she pulled out a large double ended purple dildo, “I was getting bored and just about to come out and have some fun with you.” Nora continued as she waved the dildo around. Nat just smiled and waked up to Nora. “That sounds great, I need a good fuck but I think with both of us full well have to do it in the back end, right?” Nat asked as she griped the dildo as well.
Nora lead Nat out of the kitichen and in to the living room only to pick up to string bikinis and show them Nat. they were so small that they wouldn’t cover any thing really important, they were see through pink with light pink string. “I don’t want to start yet. I want to see how these look on us.” Nora said. After both had them on they were showing off there bodies to each other at any view possible.
Nora was on the floor as her large breast flop to the sides of her and her large pregnant stomach, Nat smiled graced her lips as she look to see that the dildo was next to Nora was on the floor, Nat leaned down and picked up the dildo and looked at Nora. She slowly sat down on Nora’s stomach and made the ball in her move; Nora groaned in the feeling of the ball squish down and pressed her tunnel in a different way. Nat moved the dildo up to her mouth and began to trail salvia one side. Nat then deep throat it till almost half was engulfed before she pulled it back out. “Now time to get your side all ready.” Nat held the dry side to Nora as she began to lube it with her spit. Soon inches where inside Nora’s mouth, then Nat began to encourage it down Nora’s throat.
As Nat pulled it back out, Nat then deep throated it again, when it was as far as it would go she place it at Nora’s mouth as she began to deep throat it. When there lips touched Nat laid on top of Nora so both boobs and pregnant stomachs were rubbing against each other. Nether of them could breathe so they pulled back and pulled out the dildo. Both were red from lack of air but that didn’t stop them form continuing.  Nat then stood up and look lovingly down to Nora. “Turn over, hands and knees.” Quickly Nora did what she was told and looked over her shoulder so see Nat squat down on to the floor behind Nora, Nat lifted up the wet dildo and place one of the ends in to Nora’s ass. The movement of the dildo made the inflated ball move to adjust at having both the ball and the dildo.
As Nat got half of it in to her sisters tight ass she turned so both of there butts were facing the same way. Then Nat guided the dildo into her own ass. Her organs moved to accept the new object. When it was half in her Nat let go she slammed it in to her sisters ass. As Nora yowl in pain Nora moved back to get half of the dildo in to her sisters ass. Both were pumping in and out, their now engorged breasts were jumping up and down as were there large stomach would expand. As soon as there ass touched they would pull apart again. Over and over they drove the long dildo in to there asses, as cum began to leek out from their pact pussies.  Nora shifted her leg to rest on the table that sat just feet away from them, when she did that the dildo drove deeper into both of there asses. Nora and Nat where no longer in control of their sexual desires or their bodies, with each cum their breast would feel heaver until only their ass where moving back and forth.
Even after so long there bodies were still going, but Nat and Nora could even tell is that even with there ‘implants’ their milk was slowly dripping out of their nipples and on to the carpet. then they had stopped, their eyes where rolled back in to there head and drool escaped their mouth as milk and cum stained the floor.
