Jenny sat back on her heels, mouth agape, stunned into silence. She swallowed uncomfortably, but then rose to her feet, turning away from Natalie’s gaze. The little brunette thought Jen might now walk away in a huff, having finally seen through the prank. But then Jenny pulled the hem of her lacy lingerie up over one hip, exposing a glimpse of a firm and creamy rump cheek. She coyly looked back over her shoulder. “You mean my butt?” she inquired with a tremor of disbelief and eagerness in her voice. “You want to kiss me on my butt?”
Natalie slowly shook her head. Jenny’s expression turned into a frown of disappointment. The thought of her younger sister’s tender lips nuzzling kisses on the creamy flesh of her shapely rear had an undeniable appeal. “Tell me,” Jenny urged, unable to hide her urgent curiosity. A shock raced through her as her younger sister whispered an almost inaudible reply. “What?” Jenny rasped, feeling her throat go dry.
“On your… your butthole,” Natalie repeated, struggling to keep an unemotional monotone to preserve the illusion she was hypnotized. “I want to kiss your pretty little asshole.” Once more an almost irresistible smirk threatened to fight its way onto her lips. Surely this would at last push things too far, causing Jenny to finally crumple and admit defeat.
“That is so…” Jenny stammered, her words faltering to nothing. Natalie braced herself, waiting for the accusation that would finally send her into a fit of overwhelming giggles. So ‘sick’, ‘disgusting’, or ‘perverted’? So utterly repulsive?
“Oh god,” Jenny breathed. “That is so… hot!”
Natalie watched in shock as her older sister hooked her thumbs into the string-like waistband of her skimpy panties, pulling downward. Wiggling her sexy hips, she dragged her underwear down to mid-thigh, exposing her naked rear. The almost subliminal hint of wet pussy in the air blossomed into a heady perfume as Jenny’s naked cunt was unveiled, peeking out from between her shapely thighs.
Seemingly with a mind of their own, Natalie’s trembling hands reached up, daring to softly caress the flawless flesh of her sister’s beautiful ass. Thoughts of maintaining the joke faded as Jenny took a step in reverse, presenting her butt only inches from Natalie’s face. The younger girl’s hot breath washed over Jenny’s naked rear, raising goosebumps on the skin. Exploring fingers squeezed the firm globes of flesh, thumbs subtly creeping into the deep cleft. A gentle tug spread the soft cheeks, revealing the first glimpse within. Natalie groaned, her eyes drawn shamelessly to the cute, wrinkled pucker of her sister’s sweet little anus. A surreal sensation of light-headedness swept over Jenny as she could almost feel her little sister’s unwavering stare boring into her secret nether portal. The older girl widened her stance, further spreading her ass for Natalie’s obscenely intimate investigation.
The pretty blonde shuddered as Natalie’s thumbs slipped in deeper, prying those delicious ass cheeks open. Another wash of warm air breathed from Natalie’s lips, washing across the tender, puckered skin. The wrinkled little orifice of Jenny’s anus puckered back and forth in anticipation, presenting an irresistible lure. Natalie’s mouth watered at the sight and she licked her lips, unconsciously leaning forward. Her nose eased into the crack of Jenny’s ass, causing both girls to shiver with forbidden lust. “Hurry,” Jenny urged, bouncing lightly on her toes, giddy with excitement. Natalie steeled herself, closing the distance, determined not to be the loser in this incestuous game of chicken. It would just be a quick kiss, after all… Nuzzling her cute face into the deep cleft of Jenny’s quivering ass cheeks, she closed her eyes as if that might somehow separate her from this obscene act. She unerringly found her target, soft lips intimately brushing her sister’s crinkled, star-shaped pucker. At first contact, Jenny flinched, but then unexpectedly pressed herself eagerly back, transforming the tentative oral caress into a more urgent pressing of flesh. A brief touch was all Natalie intended, but once committed, her lips lingered, nuzzling and exploring. The crinkled flesh was so tender, and the dimpled crevice seemed a perfect, natural fit for Natalie’s pursed lips. The saliva from her open-mouthed kiss painted a glistening sheen to her sister’s quivering anus. Natalie groaned, clutching hands drawing back on her sister’s hips while pressing her lips in harder.
“Use your tongue,” Jenny shamelessly begged, feeling strange flutters ripple through her rectal tract. “Please, Natalie, stick your tongue deep into my tight little shitter!”
Any lingering thoughts of playful pranks dissolved into a mental fog. Lustful lesbian urges, long held in check, came to fruition as Natalie eagerly complied, diligently applying pressure and feeling Jenny’s tight rear portal slowly give way. She ran her tongue in a slow circle, exploring just inside the tight muscular rim. Then, heart fluttering with anxiety, she dared to dig her fluttering tongue deeper into the hot, steamy depths of her sister’s wonderfully snug asshole. Jenny groaned, her rectal tract instinctively tightening down around the oral invader, squeezing in a lustful embrace. Wet, slurping noises arose as Natalie rapidly drove her stiffened tongue in and out of Jenny’s gaping anus. Saliva oozed down her chin, hanging unnoticed in dangling strands as she dug fingers firmly into Jenny’s fleshy ass cheeks, spreading them wide open.
A tingling in Jenny’s pussy began to build. Trembling, but not yet ready to abandon herself to the sensation, she pulled her ass away from Natalie’s tantalizing oral explorations. Natalie’s hands reluctantly slipped from her sister’s hips. A shiver raced up Jenny’s spine as she felt her younger sister’s talented tongue retreat from her clutching anal grasp. She turned as Natalie eased from the bed, positioning herself subserviently on her knees. Exploring fingers crept up Jenny’s legs, finding the tiny panties still spanned between the girl’s naked thighs. She quickly dragged them downward as Jenny stepped from one foot then the other, allowing their removal.
Natalie bunched Jenny’s panties into a ball, her fingers gently rubbing the delicate white lace. She raised her hand, bringing the moist undies to her nose. Eyes closed, she inhaled deeply, savoring the intoxicating fragrance of her sister’s steamy twat. Jenny smiled and pressed her moist loins forward, breaking Natalie out of her reverent worship of the cunt-scented undergarment. Natalie’s pretty face turned upward, meeting her sister’s grinding, naked pussy. Once more that talented tongue extended, this time delving deep into Jenny’s silky fuck slot. She gasped, wrapping her hands around her younger sister’s head, pulling her face tight into her dripping snatch. Natalie’s lips nuzzled the ruffled pussy lips, then nipped at Jenny’s clit. The blonde responded with a squeal of surprise and delight as her sister’s as teeth gently closed down on the pulsing nub of hyper-sensitive flesh.
