Gareth was distracted by a swelling sensation in his chest and by the feeling of his pants tightening while his hips widened. When Chalce screamed, he shakily looked to see what made her scream. His eyes widened in an instant when he saw a monstrously huge, brown-feathered bird in the distance flying toward them. “A-- A Roc?” He grunted, his voice climbing an octave. Rocs were extremely dangerous birds imbued with elemental earth energy.
He clung to Chalce for dear life as they finally neared the island’s topside. The roc released an ear-piercing screech as it sped up and honed in on the pair. In another thirty seconds, it would be upon them.
“Hold on tight!! I’m going for the portal-- I see it!” Chalce cried out. Atop the stone island, a massive, half-circle stone arch showed itself before them. A swirling vortex of orange light filled the space.
“Ughh…” Gareth moaned as his chest uncomfortably chafed against Chalce. He felt his testicles squish into his body as his scrotum tightened; it was a bizarre sensation he couldn’t begin to comprehend or describe amidst the chaos.
The rock soared above the two and dive-bombed toward them with its talons extended. Their escape was entirely down to the wire.
Gareth saw the bird closing in on them and silently prayed for them to make it out alive. Just as the talons closed in from mere yards away, they finally crossed the portal’s boundary.
He felt relief for a split second but was quickly drawn back to how bizarre his body felt. As they traveled through the portal, the world swirled around them, and vertigo consumed him. He wasn’t sure what physical sensations were due to the portal and which were due to the potion.
His chest had grown a healthy pair of C-cup breasts that continued to grow, while his arms, legs, hips, and waist all took on a soft, feminine shape. He felt his spine crack and contort into a supple curve while his cock receded into a fleshy button nestled between the folds of what used to be his scrotum. “Hnnnng!” He moaned in an increasingly feminine voice as his new urethra and vagina popped open amidst her feminine flower.
All of a sudden, they made it to the other side. They tumbled onto the floor of a stone cave floor as Chalce lost control and crashed onto the ground. Gareth suffered only minor bruises as she sat up and placed a hand on her head with a groan. “Fuck… Did we make it? I-- wait, what!?” Her cheeks turned bright crimson as she stared down at a pair of massive tits hanging from her chest. She shakily raised her arms, noticing how soft and feminine they had become. It only took a few more seconds for her to realize she had a dragon tail, horns, and a pair of wings sticking from her back.
