An early Christmas Gift Exchange for  DanielHeroX2.0 that he did with his friends, which includes me. ^^
And now, story time.

After a few months, Mr. Kat still had some trouble getting use to being with Xandra. But now it was Christmas day, and it felt even more of a challenge, as he had to be nice to her, or no presents for him. Soon Christmas day arrived, as Coop and Millie were opening their presents from Santa, as Kat laid down, amused as, of course, he gotten no presents. Apparently that prank he did with Coop of having him catapulted out of his room and into the snow was a naughty thing. However, he did noticed Xandra coming towards him, wearing a strange red rubber diaper with a Christmas tree on it, and another on her black, a light blue one with a snowman on it.
"What do you want?" Kat asked.
"Look, we may fight, my we're still cousins, and that means family. So, merry Christmas cousin." Xandra grabbed the rubber diaper on her back and handed it to Kat. Coop and Millie excitedly went outside, as Burt had a big present for them in the front yard, giving them a good timing on privacy. Kat reluctantly put on the rubber diaper, feeling the small absorbent padding around his crotch as he gave a small smile and blush.
"Huh, not bad."
"And heres, the fun part." Xandra pulled her cord all the way, as it inflated up to her feet. "You can pull the cord as far as you can for it to inflate largely, or just a little tug to make it swell." She winked at Kat, as he blushes more. He did tug the cord a bit to see and experience it, as it did grow out by a layer or so, as the pressure felt just right, making him purr. "Hehe, is my cousin enjoying the gift?" She cooed. But before Kat could retaliate, their diapers rumbled a bit as suddenly they began to inflate more than expected.
"What the?!?" Kat was shocked as well as Xandra, their diapers started to inflate all over the living room as they reached up to the ceiling. Soon as Burt, Millie and Coop came back in, they were surprised to see the living room flooded with two different colored blobs of rubber, as they were all very confused. Kat and Xandra were above the living room ceiling, as Kat growled angrily and blushes at Xandra.
"Maybe... I added to much sodium azide." Xandra blushes a little. It was a good thing the giant mass of rubber from their diapers condensed the cracks so the others couldn't here, because there's gonna be some screams for cheers. Or just screams, once Kat figures out of to get out of this ridiculous predicament.
Hope you enjoy. ^^

The diapers were used by the art from here that my friend wanted to be like: http://www.furaffinity.net/view/27213388/
