"Hey! Check this place out!" Abby called to her sister, peering into a small antique store in the middle of a bustling boardwalk.
"Hold up, I'm coming!" Lilly replied, catching up to her older sibling. "Wow, cool!"
The shop was full of beautiful shells, hand crafted sculptures, and sparkling jewelry. The girls stepped in and started to browse the crowded shelves.
They were on vacation in Honolulu, and had taken the afternoon to venture off the beach and explore a bit of the city. Their sisterly vacations had become a sort of tradition, they'd been taking them together for a few years now. Both girls were in their early twenties, and lived in different cities, so they took advantage of the opportunity to see each other when they could.
"Woah! Check these out!" Abby exclaimed, pointing to a row of pendants made of large pink gems.
Lilly came over to see what her sister had found. "Wow! These are huge!" she said with a laugh. She pulled one from the rack, and found it was linked to a second, identical necklace. "Weird... they're stuck together." she said, holding them up to inspect more closely.
"That is because those are special pendants, my dear." The girls turned and found an older woman smiling warmly at them. "Forgive me for intruding."
"Oh, not at all!" Abby replied taking the chains from her sister. "What kind of gems are these?"
"Those are very special pieces. We call them sister crystals." the old woman replied.
"Sister crystals?" Lilly asked.
"Yes, Dear. As you can see, they come in pairs." the woman took the pendants from Abby. "They are two stones taken from one full gem." she said, holding the two crystals together. "You see? They fit together perfectly."
The gems did in fact mold together precisely in the woman's thin hands. "The idea is that two sisters can each have a pendant, and as long as they each wear it, their bond will stay strong, no matter what happens."
"Coooool!" both sisters said, their faces lighting up.
"Abby, we should totally get some!" Lilly suggested.
"Definitely! We'll take them, Miss!" Abby replied, reaching for her purse.
"Wonderful! I'll wrap them up for you." the old lady said with a sweet smile.

A few hours later, the sisters arrived back at their hotel room. Abby set her bags down and plopped on the bed, tired from their afternoon excursion.
"That bus was too damn hot!" she said, stretching her arms over her head.
"I know, right?" Lilly agreed, sitting next to her older sister. She started to rummage through their purchases, finding the small box that held the pink crystals they'd bought at the antique shop.
"Oh yeah! I forgot about these!" she said, pulling the box out from the pile. She got up, walking to the mirror and clasped one of the pendants around her neck. "What do you think?" she asked, turning back to the bed.
"It looks very pretty." Abby complimented, sitting up on her elbows.
Lilly wiped a damp strand of hair from her forehead, looking back at herself in the mirror. "Ugh... I reek. That bus was fucking sweltering. I'm gonna take a quick shower, then we can go lounge on the beach, k?"
"Sounds good." Abby replied, laying back on the bed again. "I'll be here."
Lilly giggled and tossed the second pendant on the bed. "Here's yours." she said. "I'll be out in a bit." She grabbed a towel and disappeared into the bathroom.
Abby rolled on her side and reached for the crystal, inspecting it in her hand. 'These things ARE really pretty...' she thought to herself.
She pulled herself off the bed and went to the mirror herself, fastening the chain around her neck. She admired her reflection, tilting her body to catch the pendant in the light.
'Wow! It's really sparkling!' she thought. As she stood by the mirror, she gradually began to notice a faint smell coming from somewhere nearby. 'What is that?' she wondered, turning to look around the room.
The smell grew stronger, and Abby breathed it in deeply. She found the scent intoxicating, but couldn't identify what it was. Growing eager to find it's source, she searched the room, finally deciding it had to be coming from Lilly's closed suitcase.
She hesitated for a few seconds, then opened the cover, rummaging through it's contents. She found a plastic bag filled with her sister's dirty clothes, and tore it open. She pulled out a pair of used panties, grinning excitedly as she determined it was the origin of the smell.
Without thinking, she brought the material to her nose, breathing in deeply. The smell caused her to tremble, her body igniting suddenly with arousal. She noticed a slight stain on the inside, and sucked it greedily into her mouth, tasting the crusty flavor of her sister's crotch.
Abby groaned and closed her eyes, shoving her free hand into her bottoms. She began to masturbate frantically, sucking on her sister's panties in the middle of the hotel room floor.
Lilly had started the shower and was stripping naked in front of the mirror. She admired her body, wearing nothing but the sister crystal around her neck. As she checked herself out, her mind drifted suddenly to thoughts of her beautiful older sister.
'She really is amazing...' Lilly thought, imagining the older girl's gorgeous face. Wanting suddenly to see it, she grabbed her cell phone and thumbed through her photo album, finding a picture of Abby she'd taken on the beach the day before. She was smiling sweetly, laying in the sun in her skimpy blue bikini.
Lilly bit her lip, finding her pussy was beginning to feel warm. Her stomach felt tingly, and she absently ran her hand over it, sliding it down to her smouldering cunt. "Oh... Abby..." she whispered, as her fingers sank into her gooey folds.
A noise from the other room suddenly startled her, and she snapped out of her trance, remembering the shower. She put down her phone and decided to take off the pendant, setting it on the counter top.
As soon as she did, she felt her arousal evaporate, and shook her head in confusion. 'That was a weird thought... I need to get a fucking boyfriend.' she told herself, before climbing into the shower.
Lilly's suitcase lid had fallen back, hitting the beside table and knocking over a bottle of suntan lotion. Abby jolted at the noise, her hand still buried in her shorts. She still had Lilly's underwear shoved in her mouth. She sat frozen in place, her mind beginning to clear, and her arousal almost instantly faded away.
Surprised with herself, she pulled her hand quickly from her pussy and spat out her sister's panties. 'Jesus, Abby... What the fuck was that about?' she thought to herself as she quickly repacked Lilly's clothes and pulled down the lid of her suitcase.
She stood, fidgeting nervously with her pendant and sat back on the bed, striving to make sense of what the hell she'd just been feeling and doing.
A few minutes later, Lilly emerged from the bathroom dressed in her bikini and ready for the beach. "You showering?" she asked, still patting her hair with a towel.
Abby turned to her sister, still in shock, but snapped out of it and stood. "Naw, I'll just take a dip in the ocean." she said, walking over to the mirror again. She pulled her shirt off, revealing the bikini she wore underneath. "I'm ready whenever you are."
Lilly tossed her towel into the bathroom and grabbed her sunglasses. "Let's go, then, Girlie!" she said, and the two headed out into the hall.
"Hey, where's your sister crystal?" Abby asked, noticing it missing from around Lilly's neck.
"Oh, shit! I took it off when I showered. I must have left it in the bathroom. One sec!" Lilly quickly disappeared into the room, leaving her sister waiting just outside their door.
"You'd forget your head if it wasn't attached!" Abby called after her, shaking hers with a chuckle.
Lilly grabbed the pendant from the counter, once again clasping it around her neck. The crystal glimmered again. Spinning around, she rushed back out of the bathroom to catch up with her sister.
Before she reached the door, though, Lilly paused, turning back to look around the empty hotel room. She'd gotten a whiff of something, and she had a sudden need to find where it was coming from.
Her eyes scanned the room, and stopped on Abby's suitcase. She hesitated, then started to walk towards it slowly.
Abby was still waiting in the hall for Lilly to come back from the room. After a few seconds, she found she suddenly missed her sister intensely, and fidgeted as she waited impatiently for her return. She tried to resist for as long as she could, but finally had to go see what the hold up was. She opened the room door and poked her head inside.
"Lilly? Are you coming?" she asked.
Lilly was standing in front of Abby's luggage and spun around at the sound of her sister's lovely voice.
"Yes!" she blurted. "I was on my way!"
The sisters locked eyes, and their bodies quickly grew hot as they gazed at one another. Their crystals shone brightly as they hung around their necks.
Abby cleared her throat, her face burning with discomfort. "Um.. I see you... fo-found your necklace." she said. 'Has she always been this sexy?' she wondered.
Lilly reached up, grasping the gem in her hand and smiled shyly. "Yeah... It was... er... right where I left it." she replied. 'Fuck, why do I think my sister is so hot?'
There was an awkward silence, the two sisters blushing as their eyes roamed over each other's slender bodies. "Well... w-we should get going while the sun's up, I guess." Abby finally said.
