Author's note:

This chapter is where the "V" relationship with Yuriko as the point begins to form a line to turn it into a triangle. KakaxIru bi-curious cuteness, fluff, and teasing that will obviously lead to more because there's a part 2. This part is rated M for sexual situations and language but nothing explicit. I hope you enjoy it and stick around for part 2! Please let me know what you think in a comment and don't forget to add this story to your favorites if you haven't already. :)

Thanks, and much love,

Curiosity Part 1

"Say, Kakashi?" Iruka called out to the nearly silent room save for the flipping of pages as Kakashi read his favorite little orange book on the couch of Yuriko's apartment and the purring of the contented cat resting on the arm of the chair Iruka was sitting in.

"Hm?"

Iruka's face flushed as he thought about what was going to spill out of his mouth. He knew that once he started talking, the words would just keep coming, tumbling straight from his brain, bypassing his filters, across his vocal cords, and out into the open like water over stones in a creek bed. Sensing Iruka's hesitation, Kakashi's eyes left his book to take in the slightly younger, more demure male.

Kakashi watched as Iruka mentally debated with himself, his face deepening in color and movement becoming more fidgety. Yuriko did the same thing, avoiding eye contact when there was something that she wanted but was too shy or nervous to ask for aloud, especially if it was sexual. But why was Iruka suddenly so shy and nervous? And what could he possibly want to say or ask that was causing him such trepidation? It was kind of endearing, Kakashi thought, but he doubted that Iruka was behaving that way for the same reasons that Yuriko did. When Iruka's face had gone from nervous pink to embarrassed red and he shifted uncomfortably in his seat, Kakashi was no longer so sure when he realized that Iruka was trying to hide an erection.

"Iruka?" Kakashi goaded, his interest and curiosity piqued by this new development.

"Um… right…" Iruka swallowed hard and thought 'here goes nothing' before he began his word vomit of a confession.

Iruka explained how he had noticed that Kakashi usually took the lead when they were in bed together with Yuriko and played a very dominant but not-aggressive role. Everything Kakashi said or did seemed to calm and soothe Yuriko into a more relaxed and giving state of mind, submitting to Kakashi's every word. Even just seeing it happen was enticing, Iruka admitted, and he couldn't take his eyes away from them while he waited for his turn— waited to be invited to join them in their euphoria. But now there was something that he was curious about and he was nervous to ask or even bring it up because he didn't want anything to be weird or uncomfortable between them, but it was gnawing at his conscience and had been for quite some time now.

"So, I'm not sure if it's just seeing you have that power over her and her being able to be so free, or if maybe I might be attracted to you and possibly have the same or a similar reaction to you that Yuriko does. And it's super weird for me to say or admit that it's a possibility because I've never found another man really attractive, per se, but I've seen you naked and having sex and it doesn't bother me or anything and it's actually a huge turn on to see both Yuriko and you enjoying yourselves and each other, and I'm excited now just thinking about it even though this is extremely awkward and embarrassing."

The room was silent again, Iruka's declaration and tension hanging in the air like a dense fog. Kakashi was well aware of the effect that he had on Yuriko and often used it to his advantage, getting her to relax, take her mind off of things, and just enjoy the moment both in and out of the bedroom. In the bedroom, though, it allowed her to lose herself in her desires and when she did, everyone benefitted. He had noticed that it seemed to work on Iruka, too, even if he didn't address Iruka directly, and if he was honest with himself, he had to agree with Iruka that seeing Yuriko be so overcome with lust, desire, and pleasure with Iruka was a turn on for Kakashi as well. Perhaps Iruka was onto something.

As the silence dragged on, Iruka became more and more self-conscious. He felt as though he'd just dug himself into a deep, dark hole and was now ready to lie down and die of embarrassment in it. After another seemingly eternal stretch of the unbearable quiet, Kakashi finally set his book down and sat up on the couch, making eye contact with Iruka.

"All right," he grinned, earning a confused look from Iruka. "Let's test it."

"Wait… really?"

"Sure. I don't see any harm in it and if I'm honest, I'm curious myself."

Iruka's jaw dropped, incredulous. He hadn't expected Kakashi to be so open to the idea, but now that he was, he didn't know what to say or do. Assuming as such, Kakashi chuckled to himself and beckoned Iruka to join him on the couch to which he hesitantly obliged. Kakashi took the lead, to Iruka's relief and disbelief. At first, Kakashi held Iruka's hand, taking note of how soft it was compared to his own, and also how Iruka's hand was slightly smaller but with wider fingers. Meanwhile, Iruka was surprised by how gentle Kakashi was despite the rough calluses from immeasurable training and countless battles that Iruka, himself, couldn't compare to in his own experience. Kakashi's fingers gently caressed Iruka's, taking in the smoothness and warmth of his hand, and Iruka felt a light dusting of pink rise on his cheeks. It felt nice.

The two continued with their experiment, slowly pushing their limits. It started with gentle caressing, first of the hands, then moving up the arms to their shoulders, along the jaw, and into their hair, Kakashi letting Iruka's down and Iruka slowly pulling Kakashi's mask down. Each of them had begun to blush and their expressions gradually darkened from innocent curiosity and wonder to visibly restrained lust. Neither of them had expected to get as far as they had, but now that they were there, they wondered just how far they could go and still be comfortable with it. It was their first time with another male, after all, but they couldn't help but make comparisons of each other and themselves to how Yuriko interacted with each of them, as well.

"May I kiss you?" Kakashi inquired and Iruka's cheeks burned bright red and his body tensed up, his heart racing behind his ribcage.

Just as Iruka was about to answer, Yuriko opened the door with her hands full of groceries and paused when she saw her loves together on the couch, each with flushed faces and Kakashi with half-lidded lusty eyes leaning slightly into Iruka. Without thinking twice, she simply closed the door behind her, set the grocery bags in the kitchen, and made her way to the couch, leaning over the back with a grin.

"Th-th-this isn't—!" Iruka started but was cut off when Yuriko pressed her lips to his. He sighed into it, relaxing and when she pulled away, she turned to Kakashi and kissed him as well.

"I was wondering how long it would take for this to develop. You two have been making eyes at each other whenever we're in bed together for months now," she explained, looking at Iruka affectionately while she played with his hair and leaned her head against Kakashi's.

"You're not upset?" Iruka inquired.

"Why would I be? We all can't always be together. I just want you both to be happy. And I won't lie, it has been a growing fantasy of mine to see you together since I first noticed it."

"We've corrupted her beyond repair," Kakashi chuckled and kissed her cheek. "She's fantasizing about us now."

"Don't let me interrupt," she grinned in return and moseyed back to the kitchen to put the groceries away, thoroughly amused and interested in the new development of their already unorthodox relationship.

Iruka and Kakashi watched her go before looking at each other, and Kakashi just shrugged his shoulders. With a devilish grin, he grabbed Iruka's chin and pulled him into a kiss, no longer waiting for an answer while Iruka's eyes widened and his body stiffened. It was really happening. Kakashi's lips were soft but firm against his, much like how Yuriko kissed him when she was dominant with him, but there were stark differences between the two. The first was the feeling of Kakashi's fingers gripping onto each side of his chin, holding him in place with his rough, calloused fingers. Yuriko's hands were smaller and softer, her fingers even more slender than Kakashi's and sharp, especially her nails, but she never grabbed him forcefully by the chin. She preferred to pull his hair to maneuver him to do whatever she wanted.

The second was his scent. Yuriko's scent was light, fresh, and floral with warm vanilla undertones. Kakashi's was clean but musky and kind of spicy. It wasn't unpleasant at all, but it was very shocking to Iruka how alluring it was and he realized that he'd begun to drool. He didn't remember ever being close enough to Kakashi to actually smell his scent, but now that he was, he was hooked.

Kakashi noticed that Iruka's temperature had risen slightly and breathing tempered, and he couldn't help the moan that rose from his chest. He hadn't expected Iruka to be quite so responsive to something as small as a kiss. He also hadn't expected that the knowledge that he had full control over the younger man would arouse him as much as it had. Running his hand over Iruka's chest, Kakashi found his target— Iruka's nipple— and pinched the small nib through the fabric of his shirt eliciting a gasp from Iruka and unintentionally caused his length to stiffen even more within the confines of his clothing. With Iruka's lips parted, Kakashi maneuvered his tongue to wrestle with Iruka's within his mouth, tasting and exploring the new territory.

Iruka was slowly losing himself. Kakashi's tongue roamed in his mouth, asserting its dominance over his own and Kakashi's mind-numbingly sexy scent and the slight pain from the nipple that Kakashi was still fondling through his shirt was making Iruka's head spin. When Kakashi pushed Iruka back so he was lying on his back on the couch with his head rested on the armrest, Iruka knew that he was done for. Any desire to resist was gone, replaced by the fear of the unknown, but Kakashi's scent and demeanor— much like Yuriko's— were calming and alluring and reassuring all at once.

Kakashi pulled back enough to part the kiss, but his lips didn't travel far, moving instead to caress along Iruka's jawline to his ear where he nibbled on his lobe and whispered, "This really is an interesting development, Iruka. Are you this subservient with Yuriko as well?"

Iruka blushed and turned his head away as he felt his member twitch. Kakashi's voice was so low and intimidating that it sent a chill up Iruka's spine. How did he know? He'd never been around when Iruka and Yuriko were alone together… had he? Kakashi smirked and reached up Iruka's shirt, his fingertips barely grazing against his skin, and Iruka moaned out and tilted his head back. Pleased with Iruka's reaction, Kakashi purred and suckled on his neck.

"It's fine if you don't want to answer. I'll ask her."

"Yes!" Iruka blurted out, his face deepening in color.

"Yes, what?" Kakashi demanded and bit into Iruka's neck.

Iruka whimpered, the discomfort from his erection's confinement almost unbearable. Yuriko was kind enough to let him be naked, at least, when she teased him. Kakashi was not as generous, apparently, but it was equally as exciting to be confined, he thought.

"Yes, I am. It drives me crazy when she's in charge. It was just so… unexpected and unbelievably hot."

Kakashi felt Iruka's erection twitch against his leg and an evil grin spread across his face as he pressed his leg further into Iruka's crotch, increasing the pressure within his pants and Iruka let out a sexy sound somewhere between a moan and a whine, catching Yuriko's attention as she'd finished putting the groceries away. She purred as she sashayed back into the living room and bent over to come face to face with Iruka, a diabolical grin of her own adorning her lips.

"Do it again, Kakashi… please?" she pleaded, her voice deeper and dripping with pure, honeyed lust as her lavender eyes were locked with Iruka's chocolate.

When Kakashi pressed his knee to Iruka's groin again, eliciting another haughty moan from Iruka, Yuriko bit her lip and purred, shifting the weight on the balls of her feet and creating friction between her thighs. She hummed and languidly slid her hands down Iruka's pecks and abs, intentionally swaying her breasts over his face and just out of reach as she did so, grabbed the hem of his shirt, and just as slowly pulled it with her. Her lips randomly reached out to press featherlight kisses along the freshly exposed expanse of his perfectly scarred musculature, her nails digging in just enough for him to feel the sharp pressure of them against his skin, and her core close enough to his face for him to smell her excitement. Iruka whimpered, enduring the sweet torture and knowing that if he was to reach out for her, she'd stop everything that she was doing and withdraw completely as punishment for touching her without permission. It was an unspoken rule that she enforced with an iron fist when she was in her dominant role.

Kakashi paused, awestruck. He'd never seen that look in her eyes before— the look of being completely and totally in command and loving it— and his own length swelled to full hardness. Iruka was right. It was unexpected and extremely sexy. Yuriko removed the article of clothing from Iruka's torso as she returned to her standing position at the end of the couch and Iruka panted, biting his lip and squirming, tilting his head back further to smell Yuriko's scent more. Noticing this, Yuriko giggled and gently ran her fingers through his hair.

"Such a lewd boy you are, Iruka," she crooned. "Shall we show Kakashi just how naughty your body can be, pet?"

"Y-yes, Ma'am."

"Good boy. What do you have to say?"

Iruka's pleading eyes met Kakashi who was still slightly in shock at what was happening right in front of his eyes. With crimson cheeks and a wavering voice, Iruka stammered out the sentence that would change everything: "Kakashi, will you please make me cum?"
