Without further coaxing, Ty struggled to maintain the calm and concentration he needed to use his power, so sexually aroused and flustered that he felt that my might shoot off a load in his tight tented shorts.
Fine. She wanted it now? 50%. Half bird half woman. Go. He willed it forward and immediately Eileen reacted, letting out a startling inhuman screech and moaning as she began to crackle all over.
It started with the gorgeous black fan emerging from the protrusion above her wonderful ass. It began to grow and extend swiftly into sleek black tail feathers, with a douse of white and red at its base.
"Yes!" Eileen cawed. "YES!" Her wings began to stretch out and grow across the carpet of the rumpus room, their firm black feathers growing huge and lengthy. She ducked her head toward her chest and panted as now as huge beak began to overtake her human face. The massive scythe of her orange beak grew and crackled away from her shrinking face, seemingly inflating as it parted to offer moans, cries, and increasingly inhuman squawks and trills.
The former human woman trembled and humped her ass into the air as she changed, blue eyes tearing up, a pained expression on what remained of her human face as the yellowish/cream feathers adorning her chest, neck, and face blended to orange below her giant beak.
Ty stared in wonder as his human sex fantasy lost her humanity and slipped further and further into something in between. As her huge beak continued to grow, Eileen became visibly distressed and began to grimace.
"N-Need... CAW!" She crowed. "NEEED CAWWWWWK!" She cried, whimpering and crying.
Ty gasped at the outburst as she neared her completion, staring with wide eyed lust as the now bird woman fell onto her ass, spread her legs and sat up on the carpet with her beautiful tail feathers fanned out under her. She stretched her huge flight capable wings and snapped her huge beak together several times, clicking. Her blue eyes opened, she looked over herself with her chest heaving and falling. The final touch was her long brunette hair falling completely away into chunks on the floor.
Ty watched her still big but proportional bird tits bounce with each breath. She was now firm, muscular, fit, and entirely inhuman, now part toco toucan and part woman.
Eileen gasped, held out her gorgeous wings for inspection, and flexed her longer skinnier four fingers, finding herself still able to grip and hold things. She wigged her toes and was startled to find a backwards facing talon where her heels used to be. She wriggled her toes and found they might as well be as flexible as her hands were.
She panted, needfully, and stared at Ty. She cocked her head to the side, now flooded with new sensations, hormones, needs, lusts, thoughts, instincts, and urges all at once.
"Ty?" She said sweetly, voice now melodic, yet hollow from her beak. With the strange inflection of a parrot.
"Y-Yes?" Ty gulped.
"I want to be your first." She admitted, gulping and smiling nervously at the corners of her massive orange beak. "Can I have you?"
