"O-Oh!" Eileen managed, as her body began to soak up muscle and size. Like Becca, Eileen was growing strong and powerful as her draconic form asserted itself. Maddened by lust, the smaller dragoness began licking and kissing her daughter's snout, grinding her ass in the bigger dragon's palms as her scales encased her body. Soon enough, Eileen was growing in size in Becca's hands, becoming heavier and buffer as she hardened into draconic sexiness. The kissing turned to lustful licking at each other's neck and faces, and as Eileen grew too big and heavy to hold anymore, Becca eagerly began stroking her mother's pussy with her clawed hand, a favour that Eileen returned as she grew bigger and bigger.
Unlike Becca's colourful rainbow scales, Eileen was jet black. Now taller than her daughter by several feet, the bigger dragon looked to be even more ferocious, hard edges, claws, scales, and spines growing along with the rest of her. Becca considered stopping before her mother overpowered her, but let the transformation progress further as Eileen placed a huge and heavy paw on her chest and forced her to the ground.
Eileen was lost in orgasmic lust, her huge and impossibly strong body turning her on more and more. She felt a twinge of power through her as Becca willed her to become a full dragoness, and the giant black dragon growled as her breasts began to shrink and her body began to grow more feral. The black dragoness forced the now tiny Becca's legs open and eagerly slipped her long forked tongue out to eat the smaller dragon's snatch. Becca gasped as the tongue bypassed her outer lips and snaked deep into her pussy, feeling helpless and turned on as Eileen grew bigger and bigger in the forest, soon rising above the tree line and still growing in size even as she stood on all fours. The tongue inside of the smaller dragon began to hurt as it grew along with the now giant dragon, and while she was close to cumming Becca began to squirm and cry out. Her mother lovingly withdrew the giant thing from her pussy and Becca looked up in shock to see Eileen had grown to the size of a five-story building.
The giant black dragon was a magnificent beast of draconic strength and beauty. All armored scales, sharp claws and jagged spikes, she breathed heavily above her daughter and growled deeply, which to Becca's surprise she could understand as speech.
"W-What do you mean?" Becca gasped, lying on the ground before her mother's enormous front feet.
The black dragon was now the most powerful being on planet Earth. Her power had grown along with her size. She rumbled again and Becca seemed to pale.
"N-No... please..." Becca tried to will her mom to change back, squirming as a huge hand planted itself on her body, but it was a useless gesture. The giant black dragon snarled, picked up Becca in her claws, and swooped into the air with such force that it knocked over the trees around them.
It was time to pay Ty a visit.
