Mitch was enjoying the sight of his inflating girlfriend turned inflatable donkey. He rubbed his latex body, quivering with excitement. He so envied Karissa now as she inflated. He yearned to feel himself expanding bigger, swelling with air, becoming a living balloon.
Running a hand over Karissa's swelling flank, he marveled that her body could hold so much air so easily. She was look to be a very fat donkey, all soft edges and curves. Her body called out to be squeezed and cuddled. He continued to run a rubberized hand up over her back and then to her muzzle. He gently took the air compressor hose out of her mouth, she resisted a bit, but relented when she saw a glimmer in his eye.
Mitch put the hose into his own mouth and felt the air pushing down into him, filling him up. The pressure inside him filled him with the feeling of being a balloon. He moaned in pleasure, his rubber manhood hard and rigid. Waddling to the back of Karissa, Mitch kept inflating. He pressed his belly to her hindquarters, her curved donkey tail squeaking against it.
Mitch leaned over her tail, pressing his body closer against hers. He wrapped his arms around her belly, squeezing it and deforming her body. He gently pressed himself into his girlfriend. His swelling member just barely small enough to fit into Karissa's tight opening. Finally inside, Mitch leaned all the way onto Karissa, pulling her down to the floor.
Both felt the pressure of the other as Mitch kept inflating around and inside of Karissa. Both moaned and became lost in the growing pleasure both were having.
Mitch continued to inflate, soon losing his defined shape as a man, and slowly turned more into a round ball.
This kept on until...
