Karissa was lost to all other thoughts but that of being a huge rubber donkey, swelled with air and being ridden by a rubberized boyfriend. Mitch was so tight in her that each quiver brought shivers of pleasure. She'd never felt anything like this before. She was lost in its sensations and cared for nothing else.
Mitch's motions and larger size were becoming too much for Karissa. Her extra sensitive body was being stimulated too much. She couldn't hold on for much longer. She lasted only a couple more minutes, Mitch had swelled in size, his body nothing more than a round balloon with arms and legs sticking straight out. Only is member was still inside her, swelled to a size that made it impossible for either of them to separate. With a loud bray of pleasure and ecstasy, Karissa orgasmed, sending a rush of air out of her mouth.
She deflated down, Mitch still attached to her and still inflating. Karissa stopped deflating when she reached her original size. She could move now, though walking on four legs was still disorienting. especially when she had her boyfriend as a balloon sticking out of her behind.
Karissa tugged the hose out of Mitch's mouth and turned off the compressor. Yearning for more stimulation and to reward Mitch for his, Karissa waddled over to their bathroom, and shoved Mitch in first, backing herself up. It was a tight fit, but Karissa managed to get Mitch into the shower. Once there, she began to pump back and forth on his member. He moaned in pleasure, his body deformed to fit inside the confines of the small shower.
It wasn't long before Mitch orgasmed as well, sending another wave of air out of his mouth and deflating down.
Soon, both were back to their first size. Mitch hugged his girlfriend before the two went back to the living room to use the amulet again.
