The Bet
Amber awoke to an all too common feeling; wetness. As it always was on a Saturday morning, her curtains were shut and very little light shone into the room. The nine year old tabby cat looked around the room and found the sleeping form of her twin sister, Claire on the other side of the room.
She didn't even need to slip her paw between her legs to feel the embarrassing moisture she felt almost every morning. The worst part, she felt, wasn't the presence of a soaked nocturnal diaper around her waist or the embarrassment of still wetting the bed at nine; it was all about losing the bet.
Her eyes gazed onto the alarm clock on the desk between their beds and sighed a quick breath of relief. Her sister always rose at seven o'clock and she had fifteen minutes. She slipped out of her sheets as quietly as she could and tip-toed over to their closet. To any ordinary adult fur, it wasn't a walk-in, but to the short nine year old, it was. She cracked the door open and stepped inside.
She pulled the wet diaper down and folded it into a ball. She wiped her juvenile folds with her paw and found a fresh one in the dark. In the blackness of the closet she couldn't make out the "DryFur" logo, but she knew the bedwetting pants when she felt them.
As she slipped a dry pair onto her soft little bottom, she snuck back out of the closet. The moment she slipped back into her bed, she shut her eyes and feigned sleep. I'm going to win the bet! She thought to herself, grinning from ear to ear. The only reason she wanted to win the bet was to prove her sister wrong and best the slightly-younger kitten.
At least that's what she told herself.
Fifteen minutes passed in what felt like an hour and Claire rose from her bed. "Wakey, wakey, Amber." The younger twin shook her sister and the cat opened her eyes slowly, intent on selling the fact that she was indeed asleep. "Are you dry?" Amber tried to hold her grin back and simply nodded.
Claire's face was exactly what she'd hoped to see. Utter defeat was written across the kitten's face. They both wet the bed on a regular basis but if either of them woke up dry, it was always Claire. "No way! Prove it!" Amber couldn't hold her grin back any longer and stood out of her bed.
Claire could tell just by looking at it that it wasn't full, but she didn't quite believe her own eyes. She placed her paw on the front of the pants; they weren't warm, they didn't feel heavy, they simply weren't full.
The younger kitten's mouth formed an 'O' as she realized what had just happened. The bet was a sacred pact formed between the two sisters two months earlier at the suggestion of their father, to get them to stop wetting the bed. He left the intimate details up to them, though.
They only acted on the bet once a week and the seven times that they had, Claire won. This time, Amber had rigged the game. "You win." The girl said, an embarrassed blush burning hot under her cheeks. Amber pulled her bedsheets to the side and lay down on her bed. Her sister climbed on after her.
She reached over and grabbed the edges of her sister's diaper. The thin, flexible fabric that connected the front and back of her diaper ripped with little force and the dry front came forward, revealing the also dry vagina of the older twin.
"Do I really have to?" Claire whined. Amber replied with a stern look. "I had to! Seven time!" Claire broke eye contact. "Seven!" "Okay, okay." Claire breathed deep and swallowed her pride.
She leaned forward and jammed her eyes shut; her tongue sticking out blindly as she descended. Amber shuddered as her sister's tongue touched her private area. Almost immediately, she could understand why her sister enjoyed getting this done so much. It felt like her little pussy was on fire.
Her sister's tongue was very reluctant at first, but quickly it began exploring more deeply. Her tongue ran from the bottom of her tight slit, up through the delicate folds and up to button at the top. Reaching the top made her squirm. Claire noticed this and took advantage. Her tongue danced around her little clit and her sister writhed in pleasure.
The girl moaned as her girlhood was lovingly assaulted. Her tiny nipples stood on end and she began to feel a massive pressure just beyond her vagina. It was a distant feeling, like a sound muffled through a wall, but she slowly felt it getting closer.
Her sister's tongue entered her a little as she ran from top to bottom once more. Amber moaned and giggled; her breaths growing deeper. While she passionately ate her sister's pussy, Claire couldn't help but feel a little hot herself.
She reached her paw back into her own pants and rubbed at her own puffy kitten cunt. "Claire," Amber panted. "I think I'm going to pee." The younger twin grinned internally and redoubled her efforts; focusing on the sweet clit of her dear sister.
The pressure built and built inside Amber and her moans grew more frequent. The pressure appeared to have reached its peak until Claire took their interaction to another level. Claire's wet finger slipped its way past her sister's tight opening and into her canal.
Her toes curled and her fingers grasped for her sheets as her body convulsed in a way that she could never have even conceived before that very moment. Every muscle in her body tensed up at once and her sister's finger felt like it was getting bigger and returning to its original size rhythmically.
Her inner muscles throbbed around her sister's finger and Claire's tongue was greeted with a short squirt of feminine fluids. Claire eased off, not wanting to overload her sister in her first experience. Claire had experienced exactly what her sister was going through long before she had.
Amber's high lasted for what felt like an eternity. Her sister's finger remained firmly within her pussy and she lay still. except for the heavy rise and fall of her little stomach. Claire pulled her finger out and let her sister calm down.
The twins lay side by side as Amber's afterglow set in. "That was awesome." Amber panted. "That was the best thing ever... in my life." Claire grinned. "That's only the start, sis."
