The group fell silent for a moment, contemplating on who to drink just to prove Margaret's theory true. John and Sandy looked at each
other, with huge grins on their faces, and said in unison, "We'll drink together!" Laura and Margaret fell silent, and Laura said, "Wow! Two
at once... Very unusual, but I bet it would work!" The two laid down to the river's edge right below their heads, and took a muzzle-full of
water each. The two swallowed slowly, so as not to choke to death, or to irritate their esophagus. Later, the foxes felt nothing. They
thought they wouldn't grow anymore, until the feeling hit them, and passed through each other, pleasuring each other to orgasm. "I think
we should leave them be for now," Laura suggested. "Yes... Quite right," Margaret agreed. They left, just as the growths began. John
and Sandy's bodies started filling with muscle and growth for their sex organs, wanting them to fuck, and suck nipples and dicks, etc.
They resisted the urge to do so, as they already mated, so no juices came out, but John's penis gained length and girth, and Sandy's
boobs were getting ridiculously big. They moaned in pleasure, as the waves of pleasure erupted through each. The growth stopped,
when John and Sandy were only 2 feet short of Margaret, and less muscular, but just as sexually active. John and Sandy walked on
larger paws... Much larger paws in fact. They were as big as their heads! To the campsite, Laura and Margaret were finishing up labors
of the shelter, when the otter woman came back from getting roots to tie the shelter down, and Casey arrived back from patrol. Casey
and Margaret got to know each other and their sizes, by which Casey was astounded to hear and see to believe. The foxy couple walked
back, John was eight feet tall, Sandy, just falling short of her lover, 7' 10" tall. "Whoah..." everyone said in unison. "You sure have grown
substantially," Laura stated. "I'll say! They're bigger than I've ever seen them!" Casey agreed. "Cool! Those lovers are huge!" Marian
said. "Thanks, everybody!" said John and Sandy. "Point proven! As you all say, 'In your faces,' or in our cases, muzzles..." Margaret
boasted. But someone was still eager to gain size. But who?
