Natalie’s hips jerked. Her fingers slipped from Jenny’s grip, both hands clutching desperately at the bed sheets as she bucked her hips and thrust herself hard against Jenny’s naked cunt. Alarmed, Jenny’s hand shot to her sister’s mouth, clamping down firmly just as an orgasmic scream threatened to burst from Natalie’s lips. Only a muffled squeak escaped as the young girl’s eyes widened and her nostrils flared. She lunged again with her hips, her grunts of passion stifled by Jenny’s hand. Pussy lips slithered together, tender flesh sliding easily on a glistening sheen of natural vaginal lube. Natalie’s tummy rippled as her orgasm flowered to full bloom, her loins rubbing desperately against her sister’s as the two girls scissored frantically.
At last Natalie collapsed, panting urgently as her sister’s hand pulled away from her mouth. She lay coated in moist dew of perspiration, a steady trickle of spent pussy cum spreading a sticky stain down onto the bed sheets.
With a sigh, Jenny let herself topple backwards onto the bed. She untangled herself from her sister, spreading her legs in open invitation to Natalie’s hungry gaze. “Fuck me.” Jenny mouthed in a silent come on. Happy to comply, her sister scrambled onto her hands and knees, maneuvering between Jenny’s open legs. Tentatively she reached out, gently stroking her index finger up and down the length of Jenny’s tight, slippery fuck slot. The older sister purred, slowly squirming. As the girls gazed deep into each other’s eyes, the finger slipped into the welcoming depths of the eager cunt, enveloped in a tight, clutching embrace.
Natalie stiffened her finger, forcing herself inward. Jenny grunted, feeling her incredibly tight pussy stretch to accommodate the invasion. Natalie twisted her wrist, crooking her finger to explore every nook and cranny of that sweet little twat. She withdrew, added her middle finger, and pressed both digits back in. Jenny groaned, rolling her hips in an attempt to adjust to the stretching sensation. With an effort, both fingers were buried to the hilt as trembling pink flesh constricted tightly around them. A twisting of the wrist caused the older girl to moan as a sensation of fully stuffed satisfaction washed over her.
The fingers slipped out, trailing a steady trickle of syrupy twat sauce with them. The slimy trailed oozed downward, seeping into the pucker of Jenny’s anus before dripping down onto the bed sheets to start a fresh telltale stain. Three fingers returned to Jenny’s pussy, straining against the resisting tightness to force their way inside. The girl’s hips jerked in response, her fingers reaching down to capture Natalie’s hand at the wrist. “Too much!” she insisted in a hush. Patiently, the younger girl left the three fingertips embedded, reaching up with her thumb to gently stroke her sister’s rigid clit. The pinky finger slipped lower, tickling Jenny’s tautly clenched little asshole. After several moments of loving caresses, the older girl sighed, her body relaxing.
Natalie gave an experimental push, gaining a bit more penetration. Jenny bit her lower lip, shaking her head. “It’s too tight!” she pleaded softly. “I can’t take any more!” A gentle twist of the wrist, accompanied by a flexing of the fingers stretched that uncooperative cunt just a little bit. The three digits slipped deeper, much to Jenny’s alarm. Natalie withdrew ever so slightly, bringing a look of relief to her sister’s face. Then, with loving persistence, the fingers slid back in, claiming just a tad of new territory before the clenching cunt once more brought progress to a halt. Back and forth they worked, relentlessly, until Jenny gasped, begging for mercy. But all three fingers were now buried full depth.
“No more,” Jenny pleaded quietly. Natalie looked up, meeting her sister’s concerned gaze. Unspoken sibling communication took hold as a smile crossed Natalie’s lips. Both girls knew this wasn’t stopping here. “Oh god,” Jenny moaned, coming to grips with her fate. The fingers slipped out of her pussy, then returned. Jenny felt four fingertips tickling, teasing the fleshy lips of her steamy pussy. What the poor girl didn’t notice was the subtle addition of Natalie’s thumb, tucked in alongside the other four digits. Gritting her teeth, she nervously looked at her younger sister and then slowly nodded. The four finger tips slipped in first, then the tip of the thumb. Jenny squirmed, propping her hands underneath her and elevating her hips to give her sister easier access to her straining cunt.
Natalie reached up, her other hand finding and closing on one of her sister’s beautiful tits. She squeezed, causing Jenny to inhale sharply, arching her back. Exploring fingers found a fleshy nipple. She gave it a prolonged pinch, rolling the sensitive nub between her thumb and forefinger. Jenny whimpered, drawing up her hands to cup both her breasts, pressing them together. With all the attention on her chest, Jenny was distracted from the growing strain on her pussy. Natalie relentlessly kept up the pressure. Suddenly there was a flash of intense sensation, a feeling of incredible stretching. The widest part of Natalie’s fist was lodged in the trembling grip of Jenny’s obscenely stretched cunt lips, struggling to overcome the final hints of resistance. Jenny’s hands flew to her younger sister’s wrist, locking down in a desperate grip. Natalie paused, afraid she had taken things too far. But then a smile crossed her face. Jenny, her breaths coming in short, ragged bursts, slowly began to pull at her younger sister’s wrist, urging her towards the full insertion of her fist that both girls desperately wanted. With a look of concentration, Natalia resumed pushing, timing her thrusts to match her sister’s shallow, rapid breathing.
Jenny bucked her hips and a flash of pain surged through her. Her breath rushed from her lungs as if she had been punched in the gut. When she opened her watering eyes, she saw Natalie’s stunned expression, staring in wonder at Jenny’s impossibly stretched cunt. Ruffled pussy lips trembled, wrapped in a loving embrace around Natalie’s embedded wrist. The girl’s entire fist was stuffed into her sister’s juicy twat. Natalie experimentally tugged her arm in reverse, causing tender pussy lips to flare outward. Jenny choked off a squeal of protest as her vaginal mound bulged obscenely. Her sister’s fist was locked in the loving embrace of her tight fuck slot and Jenny’s pussy was obviously going to have to undergo some serious stretching before the hand could be pulled free. This revelation didn’t seem to distress either girl and they cautiously went to work.
Slowly Natalie rotated her fist, clenched knuckles grinding a wonderful friction into the clutching folds of her sister’s hot little twat. A fist-shaped bulge in Jenny’s firm tummy revealed the depth of penetration. She squirmed in response, rolling her hips in a sexy, circular motion. Her overstretched cunt mound swelled as the fist pulled back. Then, gracefully, Natalie slid her hand deeper into Jenny’s straining fuck tunnel, watching those gaping cunt lips slide just a fraction of an inch past the crease on her wrist. It wasn’t much of a motion, but it was certainly a start. The fist rolled, right then left, and then pulled back and eased in, drawing a sigh of passion from her older sister. The springs on the bed frame gave a gentle creak as the cunt-stuffing fist bottomed out, driven ever-so-slighter deeper. Another muffled metallic squeak issued as Natalie drew back. Jenny’s hands tapped lightly on Natalie’s wrist, begging for a moment of reprieve. She shifted the position of her hips, biting her lower lip as she felt Natalie once again twist that fully buried fist. Nodding, Jenny encouraged the younger girl to continue and she lovingly forced her fist like a piston back into her sister’s sweet vaginal sleeve. Slowly a rhythm began to build — squeak, creak — back and forth, the younger sister fist-fucking her sibling’s juicy cunt, slightly deeper with every twat-wrecking stroke.
