Mary grins widely. She was hoping for a striking mile raptor, but she decided to make the best of the situation. Calming Brett down as best she could, she persuaded him to go out the back. She mean while, searched inside for something. Walking outside, Brett looked over to her, and saw her with a pump, which had two hoses attached, and a long cable going back into the house. Brett began to worry, and slowly backed away.
"Don't worry" Mary said with a smile, "I'm going to help you have fun, to make up for my error"
Brett stopped backing away
"What kind of fun?" He thought to himself.
Mary moved over, and Brett noticed that the pump was on, as he could hear both hoses hissing. Mary held her mouth open, and placed one inside, but at the same time, forced the other into Brett's. The rush of air was shocking, and Brett almost fell over due to the force. Both of them started to swell, as the air inflated them, both only in size. Mary moved closer, and began to swing her tail behind her. Suddenly, Brett felt a jolt between his legs, as Mary pushed her tail up Brett's new slit. He moaned at the intense feeling, and his tail began to swing too, Mary held him close, as they continued to inflate, almost doubling their size in mere minutes. Mary wriggled her tail inside Brett, causing him to start growling loudly. Noticing that he coul move his tail, Brett swung it into Mary. It was her turn to moan, as Brett's tail was fatter than hers, and rubber every part of her virgina. She wrapped her arms around him tighter, pushing her tail further within him. By this time, they were almost twnty feet tall, and starting to fatten out more than grow. They both felt it, as their rubber skin pulled tighter, and felt extra sensitive. Both could also feel the others tails getting rounder within them. Mary was closest to hitting an orgasm due to Bretts larger tail, but he wasn't far behind.
Now thirty feet tal, and almost twice as round as they should have been, Mary and Brett, began to find it hard to more. But just as they were about to pull away fro m each other, Mary struck her limit, and a rip appeared on her tail. As she moaned loudly, all the air from within her, passed into Brett via the tare. Brett felt his body swellng fast, as Mary slowly returned to her normal size. Brett inflated at a rapid pace, but also struck an orgasm. He couldn't show it though, as he was fifty feet tall, and four times rounder than he should have been for his size. He was completely imobile, and still inflating. Mary had stopped deflating at a mere foot tall. the rip in her tail to small to let anymore air out. Everything looked huge, and she looked around in a daze. She suddenly reallised she had to stop the pump, before Brett burst, but she'd have to use it herself first...
