The condom burst! Trapping you inside Kim's Womb

By: GiantessLover

The condom continued to balloon out as Alice's balls kept emptying its contents inside of it. You finally feel your head submerge in the slimy goo, thinking this is finally the end...when suddenly, you feel yourself being pulled out as the tip of the condom bursts open. You gasp for air as you see your former prison begin to pull back from your new location. You rush after it but the opening it was in seals shut and all light vanishes.

You walk around, feeling the slimy goo of your sister's cum up to your knees as you feel around for a way out. Then you hear Alice eek outside. Both girls discover the condom had broken. Kim is freaked cause she might get pregnant but then Alice tells her what happened to you and what she did. Kim eeps as she rubs her abdomen, now knowing she held you inside her womb. The two of them stand up, as you feel your new home shift and shake as Kim stands.

Kim is shocked when Alice now stands a good bit taller than her. Kim can feel you moving and feeling around inside her. Alice smiles, loving her new height and tits. She was only 18, and now taller and more endowed than almost any adult. They begin to discuss what they could possibly do to get you out.

Kim: "Alice....I cant believe not only is will 3 inches....but you put him in a condom...then proceeded to fuck me with said condom...."

Alice: "I only wanted to scare him....I didn't know I'd cum so much it would burst the condom. I guess I could try to fuck you again to get him out. Maybe he'll crawl into my penis?"

Alice knew you were still too big to fit into her piss slit, she would have to grow bigger...alot bigger for you to be able to fit in there. Kim nodded, and you felt your prison shift once more as she laid down. Alice smiled as she pushed her enormous rod into Kim, bringing a blast of fresh air, and some light as she pushed into her womb. You winced as you went up to her one eyed monster...and tried to push yourself inside, finding it way too small for you to fit

Alice: "ahhhnnn Kim....he's trying...but he's too big to fit in my penis...I might have to take more of the growth stuff to get big...enough for him to fit"

Kim grunted, as Alice continued to pump. She nodded and mixed up more of the stuff. Since Alice would be an amazon anyway, she added even more breast growth this time around, since her sister would be a mini giantess. Alice smiled, as she drank the mixture and began to grow bigger.

She groaned as she began to grow...you watched as her cock was stretching bigger and bigger before you. Kim groaned as she was being stretched more by her little sister's gargantuan cock. Alice kept one hand on Kim's hips but her other wandered to her growing breast. Now at a K cup and still growing. The 18 year old girl soon passed 8 feet in height, moaning as she grew more and more. Finally, her growth began to slow, and she stopped at a massive 11'3", with enormous L cup breasts, and a 18 1/2 inch long beast. You finally were able to crawl inside...but what you heard next scared you.

Alice: "Nnnngh Kim! He is almost able to fit! I just need to get a bit bigger!"

What?! You pounded on the inside of your sister's cock, trying to signal you were inside. Wait...did Alice plan this? Did she plan on getting you stuck in here in order to trick Kim into....

Kim groaned, mixing up another batch...then gave it to Alice. There was no going back...Her friend told her that she only knew how to grow Futanari women bigger, she couldn't shrink them. Alice drank it and groaned, holding onto Kim's hips and pushing her fattening rod as deep as she could as she grew bigger!

She pumped and pumped, causing you to rock back and forth inside her cock as she grew...and grew....stretching poor Kim even more. Alice's tits swelled bigger and bigger, and soon Kim could feel the bottom of the girl's R cup breasts on her back as she hunched over to hump her. Finally Alice stopped growing... at a massive 16'9" with S cup breasts. She pulled her 21 inch monster out of Kim and groaned as she began to spray her with her seed, and you!

Kim laid there, covered in Alice's cum...looking at her giantess little sister. She looked positively massive to Kim and to you she looked even bigger!
