Kat stared in at Jess, and after a moment slurred 'smells soooo good'. Her pupils were dilated and she seemed oblivious to her own nudity.
The busty redhead stepped into the shower stall. She closed her eyes and leaned down, bringing her nose inches from Jess's flat chest. Eyes still closed, she dropped lower and licked one of the remaining gobs of hardened purple semen off the femboi's toned midriff. Katrina worked her way upward, allowing her nose to guide her to the few remaining clumps of jizz.
Kat opened her eyes and finally took in the python between Jess's thighs. 'Jessica? This is... This... Oh just fuck me'.
Jess needed no urging, and lined herself up to take Katrina's wet and ready slit. Kat went into motion, standing tall before using her height advantage to bring herself down on the femboi's ready cockhead. She pressed forward and pinned Jess against the wall of the shower. Gripping the top edge of the shower stall for leverage, Kat furiously rode and bucked on her mount.
Jess realized her new endowment came with a hair trigger, and quickly erupted from Katrina's enthusiastic fucking. She could feel jet after jet of cum blasting into the womanhood of the Russian beauty.
The two slid down to the floor. The bathroom was silent except for the sound of the still running shower, pouring water down onto the stunned form of Katrina.
Temporarily sated, Jess reflected further on the nature of her new body. She noticed that after several massive ejaculations in quick succession, her balls were actually smaller. They had contracted down to the size of lemons, still large but far from their previous softball dimensions. The spongy qualities must let them expand as she gets more pent up. She also realized that the flexibility of her oversized cock was somehow a safety feature. Few bodies, especially feminine ones, can take 15+ straight inches of cock without injury.
She looked back at Kat's motionless form. Her neatly trimmed bush was gone, her mound was now perfectly smooth. Jess's eyes shot upwards in surprise and closely inspected the girl's chest. As she watched, the previously ample mounds slowly lifted and receded.
It was definitely working faster on Kat, she was easily down two cup sizes in a few minutes. It had taken Jess over an hour. Realizing her purple spunk wasn't just the same color as the hoop from the tunnel, it has the same essence. Jess was transformed in hours by a few drops, Kat just had a pint's worth stuffed into her. Of course she will change much faster.
