Indica was nervous so she kept giggling as she and her twin sister Sativa snuggled underneath the covers on Indica's bed in the bedroom they shared.
They had been wide awake and horny since bedtime when Sativa had crawled into bed with Indica and soon after, had found her own fingers traveling ever closer to her sister's white cotton panties, and then, finally, had found their way inside the waistband and then her fingers had delved into her sister's tiny wet slit, so hot and slick, and she could feel her clitoris throbbing and pulsating beneath her fingertips, and they had been busy exploring and tasting and teasing and pleasuring one another ever since.
Now Sativa had just suddenly proposed a new idea, one that had occurred to her as soon as she had heard mommy and daddy start moaning, just down the hall.
Her young and pubescent mind had grown excited and giddy at the brilliant idea that had just popped into her thoughts.
What if they watched mommy and daddy from the hallway!? They could keep playing with each other and finally get to see how it was really done! A genius idea! She grew hotter and wetter at the very thought. They just had to be careful not to get caught.
So, holding hands and giggling nervously, they crept down the hallway, both wearing matching nightgowns, Indica in pink and Sativa in teal blue, and white cotton panties. They each held their teddy bears in their other hands to give them courage.
Mommy and daddy's moans grew louder the closer they got to their doorway. Strangely, their door was already slightly ajar.
"Hmm, that's new." Indica thought to herself, but the thought was quickly forgotten upon peeking into her parents' bedroom.
She gasped quietly at the sight of mommy bent over, naked, on the bed with her breasts bouncing beneath her and her head thrown back in pleasure as daddy, also naked, was on his knees behind her, his hands gripping her small waist as he repeatedly thrust into her. His head was also thrown back.
Sativa clapped a hand over her sister's mouth to stifle another gasp. Indica was briefly distracted by the scent and taste of her own cum all over her sister's fingers. "Mmm, yum." She thought to herself and felt even more cum flood her panties, they were already practically see-through they were so wet.
Both of their mouths hung open slightly, emitting soft sounds as they began to pant in unison.
Sativa's hand slid slowly off her sister's lips and crept down into her damp panties. She was so hot and wet! Indica threw her head back and moaned quietly. "Shhh!" Sativa whispered at her sharply.
Indicia threw her a short glare and then smiled vengefully as she reached her own hand down into Sativa's soaked panties and the grin transformed into a triumphant smirk as Sativa reared her own head back and a long, quiet moan traveled up from her long elegant exposed throat. Indica, still smirking, pretended she was about to remove her fingers from her sister's slick, tight pussy. Her grin widened as Sativa grabbed her wrist and forced her fingers back into her panties and she emitted a sweet, quiet whimper and her eyes widened, silently pleading with her sister not to stop.
She was soon eating her recent satisfaction though as Sativa began moving her own fingers down deeper into Indica's own tight cunt. She felt her back arch and her eyes roll back immediately with a jolt of shock running up her spine and giving her goosebumps from the unexpected pleasure. A new hot gush of cum seeped into her little white panties and she groaned from the relief of finally being touched, not even realizing until just then that she had been subconsciously waiting for it with an anxious intensity that had made her start panting aloud.
