"Oh fuck." Jason thought. "I am a boob."
He didn't know how it happened but now he was certain. He was stuck to this girl's chest as one of her barely budding breasts.
He tried screaming but he couldn't because there was no mouth for the scream to come from. The only sound was the thump thump of Chloe's heart behind him. Jason felt his panic rising so he tried counting to ten to calm himself down. A well-known technique he only really got to appreciate after he took some medidation classes at the nearby zen buddism monastery.
He felt calmer and the only thing distracting him was the throbbing soreness throughout his body. For a second he thought that the throbbing accelerated but his pondering was interrupted by a tiny voice he heard at the edge of his hearing.
I came somewhat from his right.
"Let us grow!" it said. "Let us grow for her! Let us grow bigger and heavier!"
This was just another addition to the weirdness of the situation but Jason somehow knew it was his sister... NO! It was THE OTHER BREAST he was hearing.
The throbbing increased in speed once more and the little voice became more excited.
"Let us GROW! Let us grow to bounce and squish and be squeezed by boys!' The soreness intensified. "To feed our children! LET US GROOOOW!"
With the final 'GROOW' of the other breast, Jason felt the weirdest thing (as if his situation wasn't already weird). The gentle throbbing soreness throughout his body suddenly stopped only to be replaced with a powerful cramp. The pain was overwhelming to the point of Jason not being able to register the skin holding him in place ever-so-slightly stretching as he gained a couple ounces in fatty tissue.
"YESSSS!" Jason heard his sister breast exclaim when the pain subsided. "We were let to grow! Now let us swell more!"
The throbbing soreness returned to his body and Jason realized that meant an imminent return of the painful cramp. The painful cramp and the... growth?
"Fuuuuuck!" He exclaimed in his mind as he realized that not only was he trapped as a boob but also, just as the girl requested, one that's on a fast-track to voluptuousness....
