The Identity of the Secret Voyeur
'Whew... I think that's enough to wrap up for today.'
Yeonhee, who had been diligently typing away at her computer in her room, checked the time after finishing her daily tasks.
"It's about time to sleep."
Normally, this work should be handled by Jeongyeon, her foster mother and the actual owner of the Choi Han Group, but ever since she decided to live in this mansion as a secretary, she had taken it upon herself to handle everything.
She was quite used to the work now, allowing her to process large volumes without issue, but for the first few months, she had to focus so intently that she barely managed to sleep.
Of course, she could have streamlined the workflow within the Choi Han Group to significantly reduce her workload, but because the company belonged to Jeongyeon and Yeonji, she often took on extra work voluntarily to ensure she was doing her absolute best for them.
"Oh, come to think of it, I forgot to mention the security detail..."
Tomorrow was the day Juhyun and Yeonji were going on a date, a day that required extra attention to safety. She had always been extra cautious whenever they went out, but now that they were not just a couple but engaged to be married, she had to be even more vigilant.
'Yeonji already knows, so that's fine, but... I wonder if I should tell that man about "them"...'
Yeonji had been exposed to various dangers in the past, but she had never once ended up in a truly perilous situation. The reason was the pair of sisters—bodyguards who always watched over her from the shadows. They were so quiet and discreet that they didn't interfere with Yeonji's daily life; even though Yeonji knew they existed, she wouldn't notice them at all unless they revealed themselves.
This fact was a top-secret matter within the household, known only to Yeonhee, Yeonji, and Jeongyeon.
'It would be right to inform him, but... there's no guarantee he'll actually end up marrying her.'
Yeonhee, who felt displeased with the very idea of letting Juhyun in on the secret, thought it would be fine to keep it hidden. However, she was conflicted, knowing that if Jeongyeon found out she had intentionally withheld the information, she would be disappointed.
"Why on earth does Yeonji like a man like that..."
To Yeonhee, Yeonji was like a precious younger sister. She had assumed marriage was a distant future and that Yeonji would eventually meet a more suitable man, so she hadn't given it much deep thought. Yet, before she knew it, Yeonji had found a boyfriend and ended up in a deep, intimate relationship.
'If only that man would just leave on his own...'
Whether viewed subjectively or objectively, it was a fact that Juhyun was far from being a suitable match for Yeonji, which left Yeonhee deeply dissatisfied. This had caused some minor friction between her, Yeonji, and Jeongyeon, leaving things a bit awkward, but Yeonji showed no signs of backing down.
'Yeonji could meet a man so much better than him, so why insist on...'
Because Yeonhee fundamentally viewed men as little more than beasts, she found most of them distasteful.
'His looks, his family background, his wealth, his ability... he's lacking in everything.'
A man who didn't meet a single criteria becoming the husband of Yeonji, who could be the next successor of the Choi Han Group? Even thinking about it simply, Yeonhee felt Juhyun was completely unfit for the position.
'Well... maybe his body is decent.'
The moment she recalled his erect cock after his jog the other day, Yeonhee felt her face flush.
"What am I even thinking... I'll tell him about the bodyguards later... for now, I'll just inform him of the precautions for tomorrow."
Aside from the secrets that shouldn't be shared with others, she intended to at least teach him how to behave as a man of this household. With that, Yeonhee headed toward Juhyun's room. It wasn't too late in the night, but it was certainly a bit late for a visit.
She could have sent a text or called, but she wanted to be certain he understood, fearing he might receive the call while half-asleep and forget.
Knock, knock, knock.
"Juhyun, do you have a moment?"
"............."
She knocked and called out, but there was no response, let alone anyone coming to the door. She waited for about a minute and knocked again, but there was still absolutely no reaction.
'Is he already asleep?... I'll just check.'
Click.
She turned the handle, and the door opened, unlocked. She cautiously peeked inside, but there was no one on the bed.
"No one's here... Huh? There's a sound coming from the bathroom..."
She had thought the room was empty, but there was a sound coming from the bathroom. And...
'This scent... it's Yeonji's lotion...'
At the faint scent of Yeonji's lotion, a spark of curiosity flared within Yeonhee.
"Are they in the bathroom together...? No way..."
Yeonhee suspected they might be in the bathroom together, but she quickly dismissed the thought.
'That innocent girl... surely she wouldn't... with a man...'
To Yeonhee, who had watched Yeonji since she was a child, Yeonji was innocence incarnate. Even just two years ago, she would turn bright red and be unable to make eye contact just by seeing the thumbnail of an erotic manga she had accidentally stumbled upon. Yeonhee believed that even if she had a boyfriend, she would never do anything lewd before marriage.
Therefore, the idea that the two were in the bathroom together was, at least by Yeonhee's common sense, impossible.
'Still, you never know...'
However, recalling Juhyun's erection and the fact that he was the first man she had found not entirely unpleasant, her curiosity overcame her. Yeonhee quietly approached the bathroom.
Swoosh.
'Th-that clothing... no way...'
In the small dressing area before entering the bathroom, clothes were scattered about. There were Juhyun's clothes, but Yeonji's underwear and pajamas were also visible among them.
'N-no way, is this for real!?'
Feeling her common sense crumbling, and realizing that something she hadn't even dared to imagine was happening inside, Yeonhee walked with trembling steps toward the glass bathroom door.
It was clouded with steam, but the silhouettes visible through it were enough to send Yeonhee into a state of shock.
'Y-Yeonji!?'
The silhouette of a standing man, and a woman crouching in front of him with her legs wide open. The silhouette of those massive breasts, which she couldn't mistake for anyone else, confirmed that the woman inside was indeed Yeonji.
"Ugh♥ Slurp♥ Ugh♥ Hah♥"
'W-wait, this sound and the silhouettes, surely...'
The lewd, sucking sounds reaching her ears and the movement of Yeonji's head. Every time her head moved, the silhouette of a large, thick rod-like object appeared and disappeared.
'I-it can't be... the young lady... Y-Yeonji...'
Distraught by the shocking silhouette of the younger sister she had thought would remain pure forever, she wiped a bit of the steam off the glass door to see inside, desperate to prove her assumption wrong.
"Gasp?!"
Yeonhee couldn't take her eyes off the shocking scene, a sound escaping her lips before she could stop it.
'Y-Yeonji is doing that with her mouth!?'
Yeonhee had only seen Juhyun's erection through his clothes before. Even then, she had naturally been struck by how large it was, but now, the real thing was right before her eyes.
"Hah♥ Ugh♥ Hah♥ Slurp♥ Does it feel good, Oppa?♥"
"Yeah, Yeonji, your mouth feels great... suck it deeper."
"Okay♥ Hah♥"
Following Juhyun's command as if it were absolute, Yeonji obediently took the cock, which she had been caressing with her massive breasts, deeper into her throat.
"Gulp...♥"
A scene of a man and woman having sex, witnessed through a glass door. Moreover, seeing this from Yeonji, the most innocent person she knew, was a shock in itself.
'They've already done it?! When did Yeonji start putting something that big in her mouth...'
Simultaneously shocked and unable to look away from the lewd sight of Yeonji, Yeonhee found herself completely absorbed in watching the situation.
"Hah♥ Oppa, my pussy is itching♥"
Yeonji shook her hips slightly while serving him with her mouth and breasts, as if fawning over a male.
"Is that so? I'll make you feel good."
Squish.
"Ahhh♥ Thank you, Oppa♥"
Squish, squish, squish, squish.
Juhyun was rubbing his toes against Yeonji's pussy, and Yeonji was wearing a joyful, lewd smile.
'D-doing that!! To Yeonji!!... But why does she look so happy...'
The act of rubbing a woman's precious genitals with his feet—Yeonhee felt like she should be angry at such a humiliating act, but Yeonji, who was on the receiving end, was wearing a happy, wanton smile.
'She can make... that kind of expression too...'
It was an expression of lewdness she had never seen on Yeonji before, indirectly showing that she was enjoying the situation.
"Oppa, your cock is huge♥ But I want to suck it more♥ Like this, like this♥"
Thump, thump, thump, thump.
Yeonji, who was serving him by grabbing and shaking her massive breasts like tools, was shaking them even faster, as if trying to make Juhyun feel even better.
"You're doing great, Yeonji... I'm going to cum, so keep your mouth open."
"Yes♥ Cum for me♥ Give me lots of your thick semen♥ Blehh♥"
Yeonji's wanton face, tongue lolling out to the point of drooling, craving his semen.
"I'm cumming!"
Splurt, splurt, splurt, splurt.
"Haaah♥ Oppa's semen... it's warm♥"
Thick semen sprayed onto Yeonji's face, enough to stain it white, but only ecstasy could be seen on her face.
'Th-that much from there... that semen... haah♥... haah♥...'
And watching the scene, Yeonhee, overcome by an excitement she had never felt in her entire life, couldn't hold back and slowly began to reach her hand toward her own secret place.
