Michelle swiped some more cum from Sarah's stunned face and slinked toward Heather, sucking the treat into her mouth as she approached the new shemale slut before pulling her into an aggressive french kiss as a welcome.
'Mmmm,' said Heather when Michelle broke away, 'so it was your tent I found. Hope you don't mind but I made a bit of mess of my own in there.'
'Is that so? Maybe we should take your friend back there so she can transform in it too. What do you say?'
Sarah heard the exchange and knew that she should run, but her fingers were buried to the knuckle in her snatch and furiously pumping away. The virus was acting far quicker from swallowing Michelle's tainted seed and already her body was demanding sexual gratification.
Heather hoisted Sarah over her shoulder and then did the same with Michelle so the eager shemale could slurp on her cock during the hike back. About halfway back Sarah came over her fingers and Heather felt her friend's tits swell against her back. Memories of her own pleasurable growth spurt rushed back and she blasted a wad of sticky seed into Michelle's hungry mouth.
When they reached the tent Michelle slid off and quickly jacked off a fresh batch into the tent before stepping back to let Heather toss Sarah into the perverse cave of spunk. Then two shemales crawled in alongside and zipped the flap shut.
