Jon awoke with a painful erection. It must've been the afternoon, as the clearing was illuminated with a green hue just as it had been on his first visit. He found his lover nestled against him, her face in his lap, sleeping mere millimetres from his large, throbbing cock. After the past couple of days, he was amazed his balls hadn't fallen off from overuse.
God, he needed release! He nudged the island girl until she roused from her slumber. She was greeted by the sight of a big, proud dick. Grinning, she playfully flicked his penis and then sat up and kissed Jon on the lips.
"Good morning to you," Jon smiled, breathing heavily.
The girl took care of his morning wood with a gentle hand massage, and then went to the stream for some water. Jon had been trying not to look at or think about the girl while she wasn't nearby and he was getting rather good at it. He stood up and looked up at the tree house.
If she followed him up there, would he ever be able to get down again?
Suddenly the girl was behind him and she was holding his hand. Jon braced himself for the inevitable and turned to meet her gaze. She was asking him to follow her and without the will to resist, he did so.
She guided him through the jungle for ten minutes or more until they reached a broad cave opening in a rocky outcrop on the forest floor.
"What's that?" Jon asked, but the girl replied by dragging him towards it.
The cave was wide but very shallow, no more than 10 feet in depth and gave the impression of an alcove cut into the side of a hill. The interior was dry and cool, well protected from the heat of the sun and probably other elements too. In the far corner was a small figurine, an idol of some sort, and at its feet lay...
"...The bra!"
Jon watched as the island girl took the bra and grovelled in reverence before the statue. She quickly put the bra on and bowed again, before inviting Jon to come closer.
"What is it?" he asked. She pointed to the statue.
It was crudely fashioned into a faceless caricature of a woman with wide hips, a hug butt and enormous breasts that rested on a grossly distended pregnant stomach. Under the belly was what looked like an obscenely large erect penis. It was an idol for some weird fertility goddess, made from some pale pinkish stone.
The girl was talking again, her hand alternately pointing at Jon and the statue. She then pointed at her bra, back at him, raised her arms to the sky and prostrated herself before him, just as she had the figurine.
"What?" Jon replied. "No, that's not me. I'm not your your that thing!"
The girl raised her head and responded with some gestures. She grabbed her breasts, motioned a snake coming from her crotch, beckoned at the statue again then finally at Jon. She grovelled before him again.
"I admit, the evidence is compelling," Jon rolled his eyes," but I'm just a guy with boobs! And you saw me without my boobs earlier, remember? I'm not a god, and certainly not a goddess! Wait, what did you just say?"
And there was a bright flash.
Jon found he could no longer see the girl at his feet. His grotesquely pregnant stomach and beachball-sized breasts made it difficult to see anything that wasn't both directly in front and taller than he was. He saw waves of long, pale, pink hair resting on his shoulders and falling between and around his mammoth breasts.
His hands found implausibly broad hips and what felt like a gigantic, spongy behind. They reached underneath his gigantic stomach to find his erection had also grown significantly bigger. Thanks to his belly he could neither see nor reach the tip of his penis so he had no idea how long it was, except that it obviously was way too long.
His balls had grown larger too, to roughly the size of grapefruits, but Jon was most horrified to find between them a pair of flushed, swollen lips and a soggy, quivering slit A vagina! A cavernous, sensitive, enormous female pussy!!
Jon stumbled and fell on his great rear end. The island girl cried out and ran to his side. Her breasts had grown again and she's tossed the bra aside as it was painfully tight. Lying on his back, Jon felt the presence of his lover before he saw her "“ her hands inadvertently kneaded one of his giant tits as she tried to clamber over it in order to see his face.
One look in his eyes and the girl knew what Jon needed. She vanished from view. A moment later, Jon felt her tongue on his shaft and her fingers stroking his pussy.
He moaned in a soft, low female voice. It was a long moan and sounded almost like the moo of a cow. Jon flushed with embarrassment and his tears welled up with fear and frustration but he couldn't help it, what the island girl was doing downstairs was too good, too amazing to keep quiet about.
The island girl willingly pleasured her noisy goddess many times until the sun went down. Then she helped Jon's unearthly body back to the beach and his cabin, where he fell asleep the second his weary head hit the pillow. She returned the special bra to its place on the bookshelf and curled up to sleep obediently at her goddess' feet.
