"Let me get you properly ready," Sabina said, squirting lubricant into her hands. She worked the liquid around in her palms, then gripped both of Zoey's cocks and spread it in with long strokes. She squeezed and rubbed each of Zoey's members against one another, helping further work it in.
The sensation was pretty foreign, having her own cock rubbing against her own cock, and she shivered under the assault. That it was Sabina who was stroking her was, of course, also a source of the compromising waves of pleasure.
Thankfully, Zoey was becoming somewhat of an expert in resisting her building climax. Her days as a quickshot were fortunately over—except in the most extreme cases. Which, admittedly, this might qualify as, having both a second appendage and being played with by Sabina.
"There," Sabina said, satisfied at having lubricated Zoey up. She stepped aside, and with a hand on Zoey's ass, pushed her forward toward the contraption.
"Where'd you get this thing, anyway?" Zoey asked with some amusement and some anticipation. "Doesn't seem like the usual sex store fare."
"Custom built. Rush order."
"Just for me?" Zoey laughed. "You're too caring."
Sabina's lips quirked, then she gripped each of Zoey's cocks and pointed them toward the waist-high contraption's entrance. Sabina guided her in, pressing her ass with her other hand to urge Zoey to take a step forward.
Zoey shivered as her two cock tips rubbed against the soft, bumpy material that adorned the inside of the metal device. She grabbed each of the handlebars and spread her stance, getting herself better situated. Sabina was just as eager. More so, possibly, because she moved behind Zoey, then pressed her pelvis into Zoey's ass and forcibly pushed Zoey all the way in. Zoey gasped as her cocks were squeezed in by pleasurable material, all fourteen inches surrounded in less than a moment.
"It was meant for one," Sabina said. "That potion was a recent development. But I assume the tight fit is a good thing?"
"Y-Yeah," Zoey stuttered out, shuddering at the extremely cramped hole Sabina had pushed her into. One thick girl dick pulsed against the other, heads rubbing against both each other and bumpy material, and Zoey realized that her earlier musings about having become a pro at 'lasting' might have been a lie.
It was especially unfair how Sabina wrapped her arms around Zoey's stomach, then started pulling her out of the contraption—then pushed back forward with her own hips, guiding Zoey in.
"I set the pace," Sabina said. "If you start thrusting by yourself, you fail."
"I take it back," Zoey gasped. "Not a caring teacher. A wicked one."
"Question five," Sabina said, sounding pleased at Zoey's response. "And make sure to think it over. Don't get distracted, now."
Sabina set a slow, luxurious pace, gently tugging on Zoey's stomach to unsheathe her, with her tits pressed into Zoey's back, then a firm pressure of her pelvis on Zoey's ass to bury her all the way back in. Each long, slow stroke in the cramped space, and guided by Sabina, had white-hot sparks of pleasure dancing across her body.
Behind her, Sabina tutted. Two firm taps against Zoey's bare stomach brought her back to reality. "I said focus," her teacher scolded. "Don't you want to go faster?"
"One more time?" Zoey groaned out, realizing she'd, again, missed whatever the question had been.
This time, she managed to hear and understand the words that came out of Sabina's mouth. Through great effort she found a reply. As expected of the progressing difficulty of the quiz, it wasn't just distraction that posed a threat, but that Sabina was working into questions that brushed against the edges of her knowledge.
Zoey got the sense both of them were equally pleased she'd got it right. "Adequate," she said, which might not be praise from many others, but coming from Sabina, Zoey knew it was, "so here. Your reward." Sabina unwrapped her arms from Zoey's waist, then swung a leg over the contraption and climbed on top of it, straddling the metal while facing Zoey. She scooted forward, then leaned back and rested her heels on Zoey's hips. Zoey went dizzy at the sight—at Sabina's spread legs. And especially at Sabina's next words. "And you can remove these." She tugged on her panties' waistband.
Zoey didn't need to be told twice. She tugged Sabina's panties down, baring her teacher's pussy. For a long moment, she simply admired it. Freshly shaven, the desire to reach out and play with Sabina was indescribably intense. Her cocks throbbed in longing. She wanted so desperately to bury herself in her teacher and rut like an animal.
"My, that's a nearly predatory expression on your face," Sabina said, sounding amused. "You aren't imagining anything too uncouth, I hope?"
The instinct was too potent to ignore—she needed to channel her arousal in some way, else she'd lose control. Something close to a growl escaped her throat, and she grabbed Sabina's hips and tugged the woman closer to her, so her bared pussy pressed against Zoey's stomach. In a desperate, animalistic motion, she pulled back fourteen inches, then slammed forward back into the machine.
The assembly rattled at the impact, and already Zoey had pulled back for another vicious slap. It wasn't Sabina's pussy, but with both her cocks wrapped in a too-tight space, sliding around and against each other, it was enough to satiate her in some small way. She admired the way Sabina's tits bounced with each impact, and the surprise in her eyes.
"It's a sturdy device," Sabina said, "but I'm not sure it can hold up to a wayfarer, Zoey."
Zoey gripped Sabina's waist harder and picked up speed. The metal legs holding the machine groaned and complained at her rapid movements, the abuse she delivered as she humped desperately into its tight depths. Getting to grab Sabina's hips and watch her body bounce with each slap of her hips was almost intoxicating. The older woman slid across the metal cylinder, being pushed with each impact, only to be pulled back forward by Zoey's firm grip.
"Next question," Zoey growled. "And I want your thighs if I get it right." She couldn't settle just for using her imagination. She wanted to feel Sabina in some way.
"I don't think that's how this works," Sabina said, raising an eyebrow.
Zoey replied only in the form of picking up speed, her hips shoving back and forth with primal need.
"But I suppose I can make an exception," Sabina eventually said, shivering in an uncharacteristically telling display. Zoey losing control was having an effect on her.
The question that followed nearly made Zoey laugh. It had no business coming this late into one of Sabina's quizzes.
"Going easy on me?" Zoey said. "Maybe you want to feel me, too." Spurred on, Zoey slowed down her frantic humping and ran both her hands across Sabina's thighs, then across her pelvis creases, her thumbs brushing dangerously close to her exposed pussy. It was by far the most daring she'd been, and Sabina shivered a second time. "You want to feel me between your thighs. My hips slapping into you."
"Answer the question," Sabina said simply.
Zoey did. It was easier than the previous one, barely a struggle even in her addled state. Sabina nodded in satisfaction before she'd turned around so her stomach was on the metal of the device, then started shuffling down. Zoey helped situate her, and soon, her teacher's soft thighs were dangling off the edge, perfectly lined up to the machine. Zoey grabbed each of them, then pressed them together, sandwiching her two cocks between them.
The agonizing softness, and having Sabina's ass pressing into her stomach, laid out across a machine and ready to be thigh-fucked, was too much for Zoey. She grunted and got to work, the arousal taking control of her entirely. If her movements had been eager before, now they were frantic. Zoey's two cocks slid between her teacher's thighs and inside the tight pressure of the contraption, and it completely erased her thoughts. Grunts, moans, and slaps filled the air, along with the creaking of metal, as Zoey pistoned her hips with total desperation.
Her climax built moment by moment, and she was vaguely aware of Sabina trying to ask the next question in the series, but even her teacher seemed to realize the futility in continuing. She laid atop the machine and let Zoey use her.
The desire to pull out of the toy and claim Sabina's exposed ass and pussy was almost overwhelming, but she of course fought it away—however difficult. She couldn't completely restrain herself, though, and her hands wandered off the handlebars and started exploring Sabina's body. Her teacher didn't protest that, and Zoey fondled her underneath her bra, tweaking and playing with her nipples as Zoey panted and moaned, climax quickly building. Her cocks twitched inside their confines, and she could tell she didn't have much longer.
"Here it comes," Zoey murmured, bent over and humping desperately. "Here's your load. You ready?"
Sabina turned and looked at her. Even the stoic woman had found a blush, by this point; her thighs being rutted into so frantically, and Zoey's lower stomach slapping into her raised ass, was something even she couldn't keep a straight demeanor through. "More than ready," Sabina murmured back, gray eyes locked to hers, happy, like usual, to indulge Zoey—to play into the fantasy. "Go ahead and fill your teacher's tight pussy up. Stuff her womb with your hot cream. It's your reward for being such a good student."
It really was criminal how eager the woman was to say such phrases—especially with her usual cool composure. It completely took Zoey apart.
She groaned, then, cocks spasming, slapped viciously forward one last time, choosing to believe wholeheartedly it was Sabina's pussy her cocks were buried into, and not just the collection device. Her two members seized, and magma rolled through her veins as her climax crashed through her.
String after string burst into the plastic-like tip at the far end of the machine, and slow, long strokes helped work out the payload. She squeezed down on Sabina's thighs and worked her cocks between them, using her teacher's legs to extract as much pleasure as she could. Sabina suffered through it with a blush and a faint sense of exasperation—tolerating her student, as always. Why did that do so much for Zoey?
Finally, her muscles turned to jello, Zoey pulled out of both the device and Sabina's thighs.
"Alright," Zoey said after a few long moments of recovery, still lightheaded, and struggling to stay standing. "What was the question, again?"
