Now it was Jay's turn to play with his new mate.
Still panting heavily and equally aroused, the two birds enjoyed caressing and fondling each other with suprisingly flexible wings. They touched beaks, nuzzled, and eventually began grinding each other again, this time with Jay on top, his talon feet gripping Jane's rump assertively.
The female blue jay moaned and tweeted her bliss, feeling her lover's youthful excitement growing more confident.
As she released a second time in so short a span, her body began to ache intensely, almost as if all of her was throbbing. Startled, she turned and realized what was happening, seeing the slight grin on Jay's beak and his eyes wide with disbelief.
"It's working..." He whispered. And it was. Jane was already somewhat larger than her original size, but this was mostly to accomodate her changing body. She realized her thin legs were growing longer, her hips were growing shapelier, and she gasped as her cloaca throbbed madly. She fell onto her back, Jay tumbling from her, and felt growth and change taking her completely.
Something crackled on her wings, and through gasps of pleasure and pain she felt something moving that wasn't there before. With wide eyes, she only briefly saw a hand-like shape growing from the middle of her wings. Another intense sensation hit her cloaca, and she felt it tearing. In shock, she looked down her front with a longer neck and saw her sex organs were splitting apart from her anal tract in a strange osmosis of flesh. She threw her head back felt orgasm racking her, and when it ebbed she saw two swellings or her now humanoid torso, growing larger... and larger...
"Ah! AH!" She squawked, crackling, twisting, cortorting. She looked down herself again and saw a perfectly humanoid and deliciously feminine form beneath her sleek feathers. Her hips lead to long bird legs and she raised her new hands weakly to find her wings had grown much larger and their span wider. Her breasts, that's surely what they were, were huge and perky and as shapely as the rest of her. Two new nipples poking needfully from under her feathers.
It began to subside, and she turned her head to regard Jay, who was already well into his own process, a pink shaft of flesh protruding from her groin as he too, changed and grew in size to match Jane's form with his own manly version.
Finally, as the two bird people completed their changes, both still gasping and squirming with arousal, Jay rolled over on top of her beautiful lover and pinned her to the ground with his hands. The lustful fire in his eyes was enough to make Jane melt beneath him, and as he slipped his new bird shaft into her new bird pussy, it became very obvious why external sex organs were so much fun.
