Chapter 5: Backdoor Workout Yvette ran her cockhead down along the crack of Rhiannon's butt, and then rested against the puckered center of her anus. "What are you waiting for girl?" teased Rhiannon. "Let's see some of that defiant attitude in you like when we first met earlier." Yvette answered with a throaty growl, and pushed the head of her cock forward. As Rhiannon felt her anal rim dilating, the sensitive resistance opening and expanding, the pres-sure mounting, she exerted her muscles in a unique way, pulling in Yvette's cock without warning, her pelvic floor indenting with the pressure. Yvette squirmed as her cock entered Rhiannon's back door. Rhiannon could feel every bump and vein passing through her breached sphincter, every inch of Yvette as she forced her cock deeper in. Her anal rim was stretched to a gaping circle. "I thought that'd get your attention," teased Yvette. "Now show me that those muscles of yours aren't just rented ... " panted Rhiannon. "Grab a hold of me if you need to and really fuck my ass." "Okay, girl. You asked for it." Yvette gave a powerful thrust forward, shoving over a foot of her hard cock into Rhiannon. It sent ferocious waves of pleasure into her lower body, com-pelling Rhiannon to clench and grip Yvette even tighter. There was a pronounced pleasure in her gut as her body yielded to make way for Yvette's invasion. Yvette pulled out of Rhiannon, the lips of her clinging sphincter stretching from her body as she withdrew. Yvette began to fuck Rhiannon even harder, her thrusts accelerating, each one more violent than the last. Deeper and deeper she went, until her balls violently slapped against Rhiannon's tight ass cheeks. Yvette's breasts jiggled from her chest, swaying back and forth with every thrust, her nipples so erect they hurt. Deep in her body, Rhiannon could feel Yvette's cock rubbing against Vantha's twin pillars from the other side. Every pass of Yvette's member rubbed inside Rhiannon's rectum, driving and driving until a sensation began to simmer forth. It seeped into the deepest recess of her butt, as the relent-less piston of Yvette ratcheted into her filthy nethers. Her sphincter unclenched and relaxed, welcoming the penetration. Rhiannon's feminine nectar flowed freely from her blushing folds, running past her cunt lips and pooling on Vantha's crotch. Her grunts of effort subsided, turning to cries punctuated by a gasp each time Yvette fully inserted her cock into Rhiannon. Then, Rhiannon was moaning through clenched teeth, enjoying the felicitous burning in her contracting rectum, reveling in the mounting pressure from Yvette's thrusts. Her invasion of Rhiannon's ass was brutally repetitive, each breach only delivering more pleasure. Pleasure Rhiannon could not control. Her moans turned into ardent cries, her voice high and exultant. With every ferocious pump of her hips, Yvette drove into Rhiannon, pressing against her butt cheeks and grinding against tender flesh, rewarding the vile nerves therein. Yvette started driving into Rhiannon even faster, pounding so hard it felt like her tailbone would break, but Rhiannon didn't care. "What a little anal slut you are!" Yvette growled, "Do you like this thick cock tearing into your asshole?" She pulled her cock out of Rhiannon, seeing it coated with her juices. "Put it back in, damn it." Rhiannon uttered quietly, barely able to give voice to the words. Yvette grinned from ear to ear. "Beg me to." "Fuck me long and hard and deep, like I know you can," growled Rhiannon. Rhiannon undulated desperately as Yvette rubbed her thick cock on her backside, feeling her puffy exit sing with delight every time she grazed it. A shot of pre-cum splattered onto her lower back, its molten texture burning a felicitous path down her crack. Rhiannon moaned with need, the wanting of an orgasm becoming unbearable. "Yvette!" Rhiannon gasped, looking over her shoulder, "Shove your cock back in my slutty asshole!" Rhiannon panted as Yvette positioned the head of her hard cock to her gaping sphincter again. Rhiannon smiled deviously as she slowly took Yvette in, biting her lip and savoring every inch she had to give. When Rhiannon felt Yvette's balls pressing against her tailbone, she rose several inches above Vantha, then came down quickly. Turning her head back towards Yvette, Rhiannon paused. "Now we take things to the next level girl ... you can see what I've got in mind." She looked down at Vantha. "Start doing it to me harder, partner." Yvette and Vantha began to fuck Rhiannon harder than before, with both her holes now fully primed for their cocks. Rhiannon lifted herself up and down Vantha's shaft, her hands grabbing her tits, moans of pleasure escaping her lips as Yvette's girth stretched Rhiannon's butt. Rhiannon shuddered with each drive, with each pulsating thrust of Yvette's cock into her butt, complemented by Vantha's shafts filling her pussy to incredible dimensions. Yvette grinned, and then thrusted harder than ever before, forcing an involuntary scream from Rhiannon's mouth, then another, then another, each one more desperate than the last, each one born of the sensuous pleasure wrought from her pummeled rectum. Yvette drew back her hand and sent a ferocious slap across her ass. Rhiannon let out a squeal as her cheek rippled from the strike, sending a sweet sting deep into Rhiannon. Rhiannon purred and arched her back, enjoying the residual bit of pain from the blow, her eyes looking lustfully back at Yvette. Vantha continued to fuck Rhiannon from below so hard her body lurched forward with each thrust; soft fat rippling, hair flailing, toned muscles clenching beneath silky flesh, which reddened and glistened with exertion. Rhiannon's eyes rolled back, her tongue hung loose from her mouth, her mind nearly losing focus in the heat of passion. The feeling was rising within Rhiannon again, burning into her depths, winding a cord of tension between her holes. With each powerful thrust from Yvette and Vantha, Rhiannon managed to squeak out a constricted scream of pleasure. Vicious contractions rocked Rhiannon's body, precluding a pressure that grew, and grew, and grew. Rhiannon convulsed violently, panting like a bitch. Rhiannon squealed as Yvette's cock throbbed and pulsated, the spasms intensifying until it erupted. Hot cum flowed through her insides, filling her rectum, radiating its delectable heat deep into her bowels. From below, the pressure from Vantha's twin cocks within Rhiannon drove her to mania, a mindless beast that writhed in the winds of ecstasy, higher, higher, and higher! It exploded, sending bolts of hot pleasure arcing through her body, consuming her being in the throes of it. Spasms jolted through Rhiannon as the feeling extended from her center to the tips of her fingers and toes, causing the digits to curl in tension. Yvette roared in pleasure, and her cock exploded as she pulled out to deliver two massive spurts over her violated asshole. Then Yvette climaxed one last time, shooting a final long, pearly string of jism that soared over Rhiannon's head and landed on Vantha's face and tits. "Holy shit, it's raining in here," exclaimed Vantha, as Yvette's jism landed on her. Rhiannon gasped like a floundering fish until she finally collapsed on top of Vantha. Yvette stroked her still hard cock as her body trembled as the orgasm subsided. Rhiannon took a moment to savor the feeling of Yvette's seed leaking from her gaping ass, and she panted from the effort, the waves of her orgasm warmly soaking through her body. "Are you sure you haven't done this before girl?" panted Rhiannon. "That was one hell of a pop shot for a first-timer, Yvette," said Vantha. "You're a natural at this sort of thing." "And this first-timer is nowhere near being finished, girls ... " Yvette came around to wave her still hard cock in front of her face. Rhiannon brought the cockhead to her mouth and began to lick down the length of the shaft. It was delicious, and Rhiannon lathered Yvette's cock with her tongue until she reached her balls, then took one of her heavy nuts into her mouth, sucking gently. Rhiannon lingered there for a while, sucking each and licking the space between them, enjoying the hormone-rich musk that filled her sinuses, and the soft flesh that leaked her salty flavor upon her tongue. Rhiannon withdrew her testicle from her mouth and held both in her hand, gently massaging them as she licked Yvette's shaft from the base to the head in one stroke, her eyes adoring when they met her at the peak. Her heart pounded as Rhiannon parted her lips about her apex. Rhiannon opened her mouth wide and brought as much of Yvette's shaft as she could down her throat. Yvette pushed the back of Rhiannon's head forward, forcing her thick cock down her throat until her balls pressed against her chin. Yvette moaned with pleasure, her head tilting back, her hair cascading down her shoulders. Rhiannon smiled sexily at Yvette, a sense of immeasurable pride swelling with her as she took Yvette deeper and deeper down her throat. Spit leaked from her lips and oozed down her chin, hanging in strings before her bulging gullet. Back and forth, back and forth Rhiannon took Yvette, her throat stretching to accommodate Yvette's cock, squeezing Yvette with gentle warmth. It turned Rhiannon on to feel Yvette pressing inside her neck, to taste Yvette with every surface of her soft mouth. For several minutes, Rhiannon sucked off Yvette while she still sat on Vantha's twin pricks. Rhiannon could sense Yvette's massive cock start to pulse with orgasmic contractions. She swallowed as much as she could, her mouth quickly overflowing, as Yvettte's cock exploded, squirting cum down her throat like a fire hose. Without any warning, Yvette drove her face against her groin, the sweet stink of her loins wafting into her nose, her cock pulsing delectably. A gout of thick cum gushed down Rhiannon's throat, the delicious flavor permeating through her mouth as it filled her clenching belly. A sudden feeling surged within Rhiannon, so intense that her body shook in pleasure. Rhiannon savored the molten lust spattering her pristine flesh, a compatible sensation to the torrent that racked her body from within. Rhiannon growled with pleasure as her cunt exploded, riding a sexual wave of pleasure, from Vantha's twin towers shoved inside her cunt. Yvette watched Rhiannon ride Vantha's massive fuckpoles, her cunt gushing spunk, and getting her face totally plastered with her cum. Then she pulled and pointed her cock down, stroking herself, more full force shots spraying all over Rhiannon's face and body. When the feeling subsided, Rhiannon looked up at Yvette's grinning face, her expression a portrait of slutty desire. Rhiannon wasn't satisfied yet, and neither was Yvette.
