"Um, so Asia-san~!! Rias mentioned something to you, right?"
"Y-yes. Th-that's correct."
After receiving a call from Rias, Mitarai slipped into the Occult Research Clubroom late at night, only to find his classmate waiting. She was the girl he saved a while ago.
Mitarai remembered being surprised by her beautiful blonde hair and fluent Japanese. Silky, unblemished golden hair and mannerisms that stirred a protective urge.
"Did Rias pressure you into this or something? Argent-san, you're a member of the Occult Club and a devil… right? If you feel like you can't refuse because Rias is a King, I can talk to her, you know?"
"N-no, it's okay. I-in order to become a girl that Mitarai-san likes, p-please teach me lewd things!"
"If you're that determined, then I guess there's no helping it. Alright, if I'm acceptable, I'll teach you. First off, Asia-san, how much do you actually know about lewd things?"
"Well… I've heard that men and women have sex. But that's all… Is doing lewd things very difficult? I was a sister from an orphanage, so I'm quite sheltered. I only know what I learned at school and what Kiryu-san told me."
"Mhmm, I see. Alright then, let's start by showing each other our naked bodies. You've probably seen children's private parts at the orphanage, but you haven't seen a grown high school boy's, right? Let's start by getting used to seeing a man naked."
"Y-yes… Wh-what!? I have to get naked too!?"
"Well, yeah. You're a devil, right, Asia-san? Then it's an equal exchange. If you're going to see me naked as part of your lessons, I'd like you to show me your naked body too."
"…Uu, it's embarrassing, but I'll do my best."
Flustered, she nodded almost without thinking.
She didn't seem to grasp just how embarrassing and outrageous it was to get naked in front of a man.
Asia was a pure sister; no wonder she didn't know how to be suspicious of people. It was probably easier to live by trusting rather than doubting.
He watched intently as she struggled against her shame and slowly began to undress. Though she noticed his gaze, she steadily continued removing her clothes.
She seemed to have come in her uniform, so while the outfit was familiar, the situation of a girl he wasn't close to undressing was sufficiently stimulating.
As she shed her primarily black uniform, skin as pure white as fresh snow was revealed. True to her delicate appearance, her body was slender overall, but it meshed perfectly with the small-animal-like aura she gave off.
Perhaps her development wasn't very advanced, as her chest was still quite modest, though there was enough softness to suggest a slight valley.
The bra she wore wasn't a sports bra but a cute white one with subtle embroidery—a fittingly innocent color for her. Her panties were also white, likely a matching set.
"I-I'm down to my underwear… I-I took them off. Uu, this is so embarrassing…"
"Then it's my turn next. How do you want to do this? I can strip everything off at once. Or would you prefer I keep my underwear on like you did, Asia-san?"
"P-please keep them on. I'm sorry, even though I was the one who asked…"
"Nah, don't worry about it. Being able to see you naked is a reward for me. You can take your time getting used to it."
Unlike Akeno, who had shown her bare skin immediately after resolving herself, Asia remained shy throughout, which was utterly adorable.
Mitarai carelessly pulled off his T-shirt and then smoothly slid his pants down. Through the briefs Rias preferred, the distinct shape of his penis was clearly visible.
Even through the fabric, seeing a man's member for the first time caused Asia to freeze. However, though frozen, her gaze was riveted, staring intently at the penis visible through the briefs.
She wondered if men were all like that, but then she recalled Rias's words: Mitarai was the rumored big-dicked boy, while Issei was average-sized.
So, maybe something scaled down from his size would be Hyoudou Issei's penis? Even though she'd seen boys' private parts before, she'd never seen a grown man's penis, so her imagination couldn't stretch further.
Every time he felt her gaze, it twitched inside his briefs, and seeing that, Asia's body would give a little jump too.
"Argent-san… hmm, can I just call you Asia? As just classmates, 'Argent-san' is fine, but I'd like us to be a bit closer."
"Y-yes, that's fine. May I call you Takashi-san, too?"
"Of course, that's okay. Wanna start with a kiss?"
"…I won't force you. Ah, but if you ever feel like it, you can kiss me too. Just the thought of getting a beauty like Asia's first kiss would make me happy. Now then, we're both in our underwear, but this alone isn't enough to get used to anything. As a first step, let's hug. Let's feel each other's warmth and get accustomed."
"Yes. Um… p-please."
Timidly, Asia moved in to embrace him. As expected, her flat chest didn't convey much softness, but her scent brushed past his nose.
It was a woman's scent, different from both Rias and Akeno, and his crotch reacted involuntarily. The shampoo scent wafting from her waist-length hair and the sweet, honey-like fragrance she herself emitted. As he took a strand of her hair and sniffed it, she squirmed shyly.
"Um, is smelling my scent also necessary?"
"Well, yeah. It's important to smell the scent of the person you're going to get intimate with and feel at ease. Losing your virginity hurts, so you smell the man's scent you're clinging to for comfort. So, I'd be happy if Asia could feel reassured by my scent too."
"I-is that so? I understand. I'll do my best to feel reassured by Takashi-san's scent!"
From what Rias had said, Asia was a hard worker who, despite her naivety, would keep pushing forward bit by bit. Mitarai gave her hand, which was clenched tightly as if she were overexerting herself, a firm squeeze.
From Mitarai's perspective, as long as the end result was good, there was no need to comment. Right now, something else was more important: smelling her scent.
Not satisfied with just her hair, he buried his face in the nape of her neck, savoring her fragrance. Asia, doing as he said, inhaled his scent and let out a somewhat dazed sigh.
"It's true, when I smell Mitarai-san's scent, I feel warm all over. Why is that?"
"Hmm, maybe it's because I'm a safe presence for you, Asia. Have you ever smelled a man's scent?"
"N-no. That's still too embarrassing. Should I smell it?"
"You should hold off on smelling anyone's scent for now. First, you need to get used to mine."
He shifted the focus, changing the image of the 'safe man' in Asia's mind to him. As Rias said, she was so naive that even her romantic feelings could likely be redirected.
He initially thought stealing someone who was in love with another man was wrong, but upon reflection, the reason he could now hold women like this and his life had become enjoyable was precisely that he had taken Rias from Hyoudou Issei.
Thinking that, maybe taking Asia, who was now sniffing his scent in his arms, wouldn't be so bad.
A girl like a small animal, different from both Rias and Akeno. And because of her naivety, she would likely accept whatever Mitarai taught her as common sense without question. She didn't seem the type to look things up online later, like Akeno might. It was a strategy to implant knowledge to his liking and cherish her. Thinking this, the arm he had around her back tightened.
"Mmm... that's a little painful. Ah, but being held this tightly... makes me feel incredibly safe~!!"
Her eyes grew hazy and drowsy as she unconsciously rubbed her cheek against his chest. Like an affectionate cat, she was lost in his embrace.
Despite his penis, covered by his briefs, pressing against her stomach, she moved to increase their contact area, which only served to stimulate him further.
"S-sorry, Asia. If you get any closer, my crotch will—"
"Eh? Ah... s-sorry. B-but it's okay now. Just like you said, smelling your scent made me feel safe. Um... well... would you look at me? At my naked body?"
"Ah, of course. I'd love to see your beautiful skin, Asia."
Her trembling from before had stopped, and she could now undress naturally. Though she felt shy, he was teaching her these naughty things for her sake.
'If this was necessary, wouldn't it be rude not to get naked?' That's what Asia thought.
