Chapter 46: In the bathroom with Seo-yun

'Could this be related to kickbacks? Coming in early too...'

I glanced at Kim Dayeon walking back to her seat. At this point, there was no way to find out. 'I can't just leave my seat whenever I want either.'

I couldn't tail Kim Dayeon every time she left the office. Without a proper reason, they wouldn't even approve an outing. 'I'd love to see it. That flustered face of hers.'

Just imagining it sent a thrill through me. Kim Dayeon, who always treated me like a servant, being at a loss for words. 'Do I have no choice but to wait until she lets her guard down?'

I pondered deeply, but nothing came to mind except waiting for her to make a mistake. "Hello."

I turned my head at the familiar voice coming from behind. Seo-yun was standing there. Wearing the now-familiar white dress shirt, suit skirt, and even black stockings. "You're early, Seo-yun. It's fine if you come a bit late."

"I rested well over the weekend, so my body feels refreshed."

"You're so diligent—the president must really like you. Should I get you a latte?"

'Of course you're trying to look good in front of Seo-yun.'

"Ah, I'll just take the thought. I already had a cup on my way here..."

"If you've already had some, then there's nothing we can do. But let me know anytime you want one."

"Thank you, Department Head."

As she walked back, Seo-yun subtly greeted me. "Hello, Senior."

"Yes, hello."

Since the department head was present, I greeted her politely as usual. She returned to her seat and sat down. Not even a few seconds later, my phone vibrated and the screen lit up. '? What's this?'

[Do Seo-yun]

[Senior.]

'It's Seo-yun.'

I glanced sideways at Seo-yun sitting nearby. Our eyes met. I immediately checked the notification. [Did you have a good weekend?]

<Of course I did.>

Though the only thing I remember is having sex with Ha-rin. <Did you have a good weekend?>

[I didn't.]

[I was waiting for someone's call...]

Instinctively, I knew she was talking about me. To stop her from acting out on her own, I'd told her to stay put until I gave her permission. 'Has it not even been ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠a week? Wednesday was the last time... I should probably give her a release.'

If I left her alone, she might come back with another rotor inside her body. Or she might call me to the storage room like last time. <Oh dear... What am I going to do with this impatience of hers?>

<After work, come to the second-floor restroom.>

'The second floor is the bank, so no worries there.'

By 6 p.m., even the bank employees would have left. There was no reason for anyone to be there. [Okay.]

'At least yesterday ended with just one round, so that's a relief.'

Even though we'd only mixed bodies on Friday and Saturday, my physical condition wasn't bad. Ha-rin must have been tired too, since we only did it once after waking up in the morning. 'If I want to leave on time today, I'll have to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠work hard again.'

I organized the documents I needed to review while working. ***

[Monday | PM 6:11]

"Alright, everyone worked hard today. Time to head home."

'What's this? They didn't leave on time today for once.'

"Good work today."

"Take care."

As Kim Dayeon left, the deputy manager and section chief also headed out. 'I should go down too.'

[Do Seo-yun.]

<Just come down to the second floor.>

[Yes!]

I grabbed the bag I carry for commuting and left the office. Straight to the stairs. Down to the second floor. 'As expected, the lights are off.'

The bank was dark, with only the hallway lights on. Ignoring the bank, I headed straight into the restroom. The door creaked open. 'No one here, as expected.'

I checked if anyone was inside the restroom. 'The stalls too... No one.'

There was no way anyone would be there. The bank stopped accepting customers by 4 p.m., and all employees left by 6. In a way, it was safer than the storage room. 'I guess this counts as outdoor sex too, since it's a restroom.'

I entered the stall at the very end.

The trash can was spotlessly empty, as if someone had cleaned it before leaving work. [Do Seo-yun]

<Did you come down to the second floor?>

[Yes, I'm in front of the restroom now.]

<Go straight into the men's restroom, the very last stall.>

[The men's restroom?]

Even though it was just text, I could sense a flustered hesitation. It didn't seem like the same person who was always pushing me forward. <Yeah. There's no one here.>

<Don't be scared, just hurry in.>

About ten seconds after sending the message, I heard the same creaking sound I'd made when I opened the door earlier, followed by footsteps. The urgency in them made it obvious who it was. 'Definitely Seo-yun.'

The footsteps stopped right in front of the stall I was in. A shadow fell beneath the door. Knock knock. A timid knock sounded from the other side. "Se... nior?"

Her voice was barely a whisper—no, more like a squeak. I opened the door. Seo-yun stood there. "Come in."

Her face was flushed deep red. She was so worked up that even her ears, peeking through her blonde hair, had turned bright crimson. "Excuse... me for a moment."

"Why are you so stiff? And why is your face burning up like this?"

"It's my first time in a men's restroom."

"You were the one who jumped at me first in the archive. And there were way more people in the hallway."

She seemed like a completely different person now. "Th-that's...!"

When my hand reached between her skirt and blouse—right where her pussy would be—she couldn't even form a proper sentence. At the same time, I felt dampness at my fingertips. "You can... lock the door...."

"Who's gonna come in here at this hour? The bank's lights are off, so the staff must've already left."

Her body, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠already trembling, shook even harder as I lightly rubbed my fingers against her. The wetness on my fingertips grew more pronounced. "And why is this pussy so wet already? Even though you're embarrassed."

"Hng... Just thinking about doing it with you again after so long... I got excited."

She pressed her body against me. The soft friction of her skin and the intense peach scent that grew stronger the closer she got made my cock throb with blood. "You were looking forward to it?"

"Yes...."

Seo-yun nodded with a dazed expression. It was like she instinctively knew how to rile someone up. "Then live up to my expectations."

I undid my belt and pulled down my pants and underwear. No more obstacles. My fully erect cock sprang free. "Lick it."

She knelt down in front of me.

After staring for just a moment, I reached out to grip the shaft and slowly shook it. "It really is firm... Senior's cock. Haa..."

Smack. As if greeting it, those pretty lips puckered out to plant a kiss on the glans before her tongue began licking. 'I'm going crazy.'

The warm, wet tongue's physical stimulation was good, but the visual and psychological stimulation was no joke. Seo-yun, who had been raised so delicately, was now crouched in this cramped restroom, licking my cock. 'Is this what they call a sense of moral corruption?'

Haa. Baa. Lick. Lick. The sounds reaching my ears were impossible to ignore. Maybe because it was so quiet, but her breathing and licking sounds were even louder. "Are you okay?"

"Mhm. Feels amazing."

Maintaining eye contact, she licked from the glans all the way down to the shaft and root. Soon, it was hard to find a spot on my cock that wasn't glistening with Seo-yun's saliva. "This much is enough."

I took out a condom from my bag. It was an ultra-thin one I had secretly bought at a convenience store earlier that afternoon while running Kim Da-yeon's coffee errand. "Give it to me. I'll put it on for you."

"Here."

It was on in an instant. "Done. Oof."

I lunged for Seo-yun's lips as she stood up. Whether she had brushed her teeth before leaving work, a peppermint scent lingered. Her stiffened tongue quickly adjusted to the situation. Chu. Slurp. Suuuck. Juuuck. Mixing our tongues, I groped her chest. Through her blouse and bra, I could feel the softness of her breasts. After kneading them freely over her clothes, I undid the buttons. Soon, bare skin and her bra were exposed. "Haaah..."

After fondling her over the bra, I pushed it aside to touch her bare breasts. The stiffened nipples swelled firmly against my palms. At the same time, Seo-yun leaned into my touch as if asking for more. I slid my hand between her skirt and blazer. "Mmm..."

Her panties weren't just damp—they were soaked. Simultaneously, Seo-yun let out a lewd moan. While fondling her breasts and pussy, we exchanged saliva. Sluurp. Juuuck. Until exhaustion slowed our movements. "Haaak... Haa..."

Seo-yun, her face flushed red, panted heavily. A silver thread of saliva stretched from her lips before falling onto her chest. "Now... put it in, Senior. You can tear the stockings."

"Tear them?"

I tried to take them off. "Yes, I always carry spares in case of runs."

"Really?"

Just like Ha-rin had done, I grabbed and tore the stockings. Through the ripped fabric, her pale thighs and gray panties came into view. The gray panties, thoroughly soaked with her arousal, had darkened. "What's with these panties?"

"I got excited thinking about being with Senior..."

Pulling the panties aside, I checked her pussy. Squelch. Squelch. As if proving they weren't wet for nothing, even the slightest movement of my fingers produced wet sounds. Seo-yun's legs trembled sweetly. "You're really turned on, huh? At this rate, I could probably slide right in."

I pressed my condom-covered cock against her. Before insertion, to ease the tension, I rubbed it against her outer lips. "Hng... Feels good."

"Does it feel good even without putting it in?"

"Yesss..."

'Maybe it's because of her heels, but I could probably enter her like this.'

"Then I'll put it in."

"Yes..."

I pushed in. Squelch. "Ughhk!"

'It's gripping me tight right from the entrance.'

Whether it had returned to normal or not, her vaginal walls clenched tightly around me. Even through the condom, I could vividly feel every intricate fold. "You okay?"

"Haa. It feels good, so... put it all the way in."

"If you say so."

Grabbing her slender waist exposed by her blouse, I pushed all the way in. "Eek?! All the way...!"

The tip of his glans touched her cervix. The moment it made contact, the vaginal walls tightened around him from all sides as if warning him to be careful, and Seo-yun's shoulders trembled slightly. They were so close that even their breaths mingled. Their eyes met. "Senior... ."

There was no way he'd let this pass. Gently closing his eyes, he leaned in for a kiss. How many people could resist this sight? Smooch. Peck. Peck. Smack. Squish. Slurp. Squish. Squish. Mixing their saliva again, he began moving his hips. With each thrust, the sound of the wall creaking, the wet squelching from where their bodies joined, and Seo-yun's increasingly ragged breathing only heightened his arousal. "Mmm... Hmm... ."

'She's close. Is it because she's so turned on?'

The more he moved, the tighter her walls clenched around him, and her trembling grew more intense. 'Let's send her over the edge while kissing.'

He increased the speed of both his tongue and his thrusts. After about ten more strokes—her body writhed violently. "W-wait, Senior. I-I'm coming... ♡"

Squelch! Sploosh! The moment he pulled out, a gush of fluid sprayed out, forming a puddle on the floor—not just once, but in continuous spurts, leaving a sizable mess. "Hahk... Haa... Haa... ."

"After five days, you really let it all out, huh?"

"B-because you made me feel so good, Senior... ."

"Turn around and lean against the door."

Following his words, Seo-yun pressed her hands against the door, bending over. "... Like this?"

"Yeah. I'm ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠going in again."

His cock, still hard and unsatisfied, pressed against her entrance. "Yes. Put it in."

He slid inside, the familiar ridges gripping him once more. The hands that had been gripping her hips now moved to grope her chest—or tried to, at least. Creak. "Hah... ."

If only the sudden sound of someone else's voice outside hadn't interrupted them. "That's weird."

Oddly enough, his mind sharpened in the urgency of the moment. Worried the noise might give them away, he covered Seo-yun's mouth. "Where did I put my wallet?"

He focused on the voice coming from beyond the door.
