Chapter 2: Her Body
Hearing Nikki's confession, Katie almost threw herself at her sister. She hugged her so tightly, she was trembling.
"You're crushing me, Katie." - Nikki said as she inhaled her sister's scent.
"Sorry, did I hurt you again?" - Katie replied and eased the embrace.
"No, it doesn't hurt, just relax a little, you're trembling." - Nikki said and added tenderly - "Don't worry, I'm not going anywhere."
She heard her sister cry out in a happy laugh and it filled her heart with warm happiness.
After a few seconds, they both fell silent, enjoying the embrace. Nikki was full of love for this girl - "I know this sounds a little corny, but I wish tonight would go on forever."
"It's not corny, it's true. I wish this would go on forever too." - Katie replied in a tiny voice
Nikki took a deep breath from between Katie's hair - "Katie, you smell so wonderfully."
"Thank you." - Katie whispered softly - "You do too."
Nikki could feel Katie's hot breath on her neck. It felt so wonderful, Nikki thought she would die.
"Say, Katie?"
"Yes?"
"Would it be OK if I kissed you?"
When she felt Katie hold her closer again, she quickly added - "It's OK if you don't want to, I understand."
"Wait Nikki." - Katie stopped her. She drew her head back and looked Nikki into her eyes - "I would love to kiss you. I was just so happy to hear you ask it. I didn't have the nerve to ask you, cause I was afraid you would say no and I would lose you again."
Nikki smiled and gently touched Katie's nose with her own, rubbing it from side to side. She brought her right hand from her sister's back to her neck, gently touching and stroking it from behind. When Katie closed her eyes, Nikki did the same. She turned her head slightly to the left as she felt her sister do the same in the other direction. Then she felt her sister's beautiful scent again. She inhaled it deeply and opened her lips slightly.
Then her mouth finally made contact with Katie's soft lips. She was kissing this beautiful young girl, a girl she knew almost all her life, a girl she loved more than anyone and who loved her back. They kissed playfully years ago when they were younger, but this time it was different. This time their true love for each other made it significant.
She remembered the last kiss with her boyfriend and realized how much better this kiss felt. Her sister's mouth was incredibly soft and gentle.
She held Katie close for a few seconds, their lips pressed together. Then she pulled away and their mouths parted with a soft, loving sound.
When their eyes met again, Nikki couldn't help but whisper - "Katie, you are so beautiful." - and she really meant it.
"You really think so?"
"Yes, you are the most beautiful girl in the whole world" - Nikki replied and felt her heart skip a beat when she saw a smile brighten Katie's cute blushing face.
"No, I think you are prettier." - Katie said and after a few seconds added - "Sorry to ruin the moment, but I think I need to blow my nose."
Nikki smiled at her sister's sincerity - "Me too, it's the crying. Wait here, I'll go get tissues."
A minute later she returned with a box and sat back down next to her sister. By the time they cleared their noses and wiped the drying tears, the box was empty. Katie asked - "Can we kiss again? Like grownups this time?"
Nikki nodded and moved closer. She closed her eyes again, as did Katie.
When their lips met again, Nikki opened her mouth and carefully stuck out her tongue. She felt Katie do the same. First they just touched each other's tongue tips, but after a few seconds they both grew bolder and they let their tongues dance and explore each other's mouths. She could taste her sister's sweet scent. It was so exciting they both started to breathe heavily, with an occasional moan escaping between their lips. They grabbed their necks and heads and pressed their bodies together as hot passion engulfed both of them.
Nikki's head was spinning. It felt so good, she couldn't stop. Again, there was no comparison to her boyfriend, kissing her sister felt so much better. She wanted to tear Katie's clothes off and make passionate love to her right there on the floor. Then she remembered she is the older one and is supposed to be responsible. She never expected a mutual confession, let alone so much passion between them. She wasn't really prepared for this situation. Now she had to repeat to herself that Katie's happiness was the most important thing and it was her responsibility to restrain herself. Slowly, if reluctantly, she closed her mouth. She felt Katie's tongue linger in her mouth for a while, then quickly returning as Nikki closed her lips and withdrew them.
Still in a tight embrace, the siblings looked into each other's eyes again.
"That felt amazing." - Katie said with a happy smile and longing in her eyes and lips that once again tested the limits of Nikki's self control.
"I think so too." - Nikki agreed, smiling as well.
"Hmm-" - Katie moaned softly and closed her eyes - "That's so nice."
Nikki realized she had been gently stroking Katie's neck with her fingers. Hearing Katie's soft moans made her heart beat faster. Again, she remembered her obligation to restrain herself and stopped moving.
