Ping

Tenten stared at the little case. Her mind froze. Gai continued to grin.

“What…,” she began, though the rest of her sentence had yet to exist. Gai faltered for a moment. The two silver-white orbs glinted innocently. They connected with a soft cord.

“It’s stress relief!” Gai explained cheerfully. Tenten met his gaze incredulously. “You roll them around in your hands!” Her look became all the more dubious.

“No,” she said at length, refusing to look at the little balls. “Those are Yin-Yang balls. The balls in this case are Ben-Wa balls.”
Her voice was slow, meticulous, to avoid faltering or stuttering. Gai’s grin became forced.

“Oh. Is that it?” he asked, sweating lightly. His thumbs-up sagged. Tenten nodded seriously. “The salesman said they were for stress relief…,”

“In a way, they are. Not the way you intended, I’m sure,” she said lightly, trying to soothe the awkward atmosphere. A brief pause followed. “Thank you kindly for the thought, at least. It’s not your fault, Gai-sensei!” she called happily, flashing him a grin and returning his thumbs-up. He seemed to brighten.

“Of course! It is the thought that counts in every gift! How foolish of me to ignore that principle!” He let loose a raucous laugh, throwing his head back to the heavens. Tenten relaxed some, glad to know that the relationship between her and her sensei was not forever tainted. Gai gave her another thumbs-up, and laughed all the way to the corner. She sighed, staring at the little set of ghostly silver balls. They were very pretty…

Endless minutes of hard contemplation later, Tenten was sitting on the closed lid of her toilet, knees spread and panties around her ankles. She coated the heavier ball in rarely used lube, slipping the cool orb into her hot sheath. A slight muffled pinging noise rang back to her. Tenten coated the lighter ball equally, tucking the gentle cord in before it. Both balls now snug inside, she took a moment to get used to the fullness. Wriggling experimentally, Tenten loosed a soft moan. They rolled deliciously against her walls, pinging gently. She could get used to this.

A glance at the clock told her that Neji was waiting for her at the training grounds. She pulled her panties and pants up, rushing slightly. The act of walking briskly to her door made her hum. The act of jogging down stairs made her gasp. The act of sprinting to the training field made her cry out softly.

“How am I going to make it through training without creaming my pants?” she asked herself, though the question was one of naughty anticipation. Her run slowed as she caught sight of the Hyuuga prodigy on the edge of their training grounds. He looked mildly irritated.

“Nice of you to show,” he said, eyeing her flushed face with some scrutiny.

“I was held up by Gai. He… gave me a gift,” she explained, not at all bothered by his mild insult. Neji relaxed slightly, eyeing Tenten as she let loose a cheerful laugh.

“You should spend less time with them. They’re affecting you in frightening ways…,” he commented.

“Oh, psh. I’m just happy,” she replied. “Let’s train!”
Neji strode to his place at the top of the field. Tenten followed, awaiting instructions.

“I think we should work on your strike speed today,” he said, beckoning her closer. “Give me a few good punches. Light strength,”

Tenten slid back into a loose fighting stance, readying her arms by swinging and stretching them. She launched forward, landing a series of light blows on Neji’s defensive forearm. Her face grew flushed as the balls pinged within her, slipping and rotating as the little weights shifted. Neji mistook it for exertion.

“Stamina, as well,” he said to himself. “But good speed. Try again, but really loosen up your shoulder. The blow should start at your leading heel,”

She managed to land an extra blow in the same amount of time, moaning softly beneath the sound of impact. The orbs had pinged again, reacting to her speed. She was becoming a bit moist. Tenten was relieved in the moment she stood still, as Neji gave her another tip. Her strike count almost doubled with the next attempt, and he seemed satisfied. “Good,” he said, raising an eyebrow at her slight wriggle. She exhaled as they rolled slowly, gripping at her slick walls. “Let’s improve your kicks.”

Tenten shuddered involuntarily at the thought. How would it feel then? Would they jiggle in the midst of a roundhouse? Neji held his palms at chest level, Byakugan activating at a low stage. Two veins came to life on either side of his face. “Come at me, mid strength. Roundhouse, try to get consecutive hits in,” he ordered, squinting at her chakra level. It did not seem depleted, as her flush indicated. It was boosted, in fact, along with her pulse and respiration. As she spun a leg into the air, he caught sight of something. The blow landed, quickly followed by a turn and a strike from the opposite foot. As she stilled, he noticed the spike in her vitals. Something shifted in her body, and he allowed his Byakugan to pulse a bit more. It looked like two balls in her… oh. He cleared his throat, clearing the confused expression from her face. Neji willed the blush on his neck to recede.

“Neji? Are you okay? Did I do something wrong?” she asked, her voice a little rough and sensual. He coughed once more.

“No, no, I’m fine. That was good. Very nice. Try to pivot a bit faster next time; utilize the momentum from your first kick a little better,” he responded, taking note of the little shift in her hips. His mind conjured up the image of those two balls, shifting and clacking in her secret places. One more shift of the hips and she swung her leg at him again, mouth opened in what could be a battle cry, or perhaps the effect of those little ministrations within her…

She managed to swing around faster, sending a flat kick to his palms. He recoiled a bit with the impact, distracted by his thoughts. Tenten let a little moan, well hidden in her heavy exhale, but Neji heard it all the same. He thought of the numerous responses her body must be making: the flush on her skin, the tightening of her core, maybe even a little wetness on her cotton panties. Neji groaned lowly, but disguised it with a cough.

“Is your throat okay? You seem to have a tickle or something?” she asked, shifting her hips once, twice, in a wider motion. He watched the movement with dark eyes, and felt the growl in his throat.

“I’m fine,” he said, watching her shift a third time. “That was much better. Why don’t we break?”

“I’m really not tired. Are you sure?” she asked, absently swaying at the hip. Her breath was hot, and Neji could very nearly feel the heat of her body from where he was. Tenten’s arms had folded across her chest, and that was when he heard it. With one last wide sway, he heard a delicate pinging.

“Oh god,” he whispered, growling openly. Tenten raised an eyebrow. Inconspicuously shifting his black covering so that it would shield his newly acquired half-erection, he tried to recover. “Why don’t we sit by the river? It’s cooler.”

“Okay,” she replied, not really noticing the shift. He paced briskly, not waiting for her to catch up. Pausing by the riverbank, Neji focused his gaze on the intricate pattern of the shallow rapids upstream. The river widened and calmed some downstream, creating a manageable current. Tenten peered over his shoulder curiously. Her body heat coated his back. “Whatcha looking at?” she asked, wiggling a bit. Neji exhaled slowly, purposely forcing those thoughts from his mind.

“Just the river,” he responded. Tenten giggled to herself, brimming with joy. She rushed ahead of him, kicking off her sandals and hastily rolling up her red pants. Plopping down on the bank with a brief pianissimo chorus of muted chimes, Tenten flung her feet into the cool water. Humming softly, her torso leant back against the grass, causing another shift in the balls. Neji shut his eyes for a moment, trying to reason out the situation. “What was Gai’s gift?” he asked softly, trying not to load the question. Although it was an excellent effort to sound nonchalant, Tenten knew from experience that Neji never asked casual questions.

“Why do you ask?” she replied, leaning up on her elbows to look over her shoulder at him.

“Curiosity,” he replied, sitting full lotus. His eyes fell shut out of habit. Tenten hummed again, leaning on one side to get a better look at him.

“He gave me what he thought was a device to improve manual dexterity and relieve stress,” she answered at length, laughing softly. One silver eye opened to a crescent moon slit.

“Really? What was it in actuality?” he asked, catching the oddities in her phrase. Tenten laughed melodically, falling back into the grass.

“You’ll never guess,” she teased. Neji stood suddenly in order to sit beside her.

“Oh? I think I have a guess,” he said, lying beside her in the cool grasses. Tenten laughed again.

“Really? What do you think then?” she asked. Neji shuffled his prone form a little closer, tracing a finger on her hip. As was her habit of the day, she shifted under his gaze in order to feel the little silver-white balls. His hand slid beneath the waistband of her pants and bypassed her panties as well.

“I think,” he began softly, opening her folds with two fingers teasingly. Tenten held his smoldering gaze, overwhelmed by the sudden onslaught of new and pleasurable sensation. One finger slipped to the source of her wetness, pushing into the sheath of muscle until he felt the smooth surface of the lighter ball. “That Gai made a very convenient mistake.”
