Arousal from Betrayal
For the first time in ages, Eun-ho's mood swung wildly from the morning. He scooped up a bite of food from his tray in the cafeteria, then paused. Last night's scene flashed through his mind again. Ye-rin gripping the washing machine, her ass thrust out. Woo-hyun moving his hips from behind. Ye-rin's moans—hah-eut, haaang. Her side profile, gasping with an expression she'd never shown Eun-ho. The Ye-rin he knew was always passive during sex. But last night had been different. All that passivity had only been for him. That realization pissed him off the most. It scraped at his pride. Rage boiled up. Yet strangely, beneath that anger, something else writhed. The sensation of his cock raging hard in his training pants last night still felt vivid. Eun-ho couldn't understand himself. He should be furious. Grab Woo-hyun by the collar, scream at Ye-rin that he knew everything. But weirdly, he didn't want to. Recalling the scene excited him, and he hated himself for it—but even that disgust became part of the thrill. He stabbed his spoon into his rice and sat there blankly. The chatter of students around him felt distant. Ye-rin's expression riding Woo-hyun. An expression she'd never once shown him. Tongue slightly out, eyes half-closed, panting. Eun-ho shook his head hard. On the flip side, there was something to look forward to. A girl from the women's judo team was coming to train with the men's team today. The coach had mentioned it yesterday. He didn't know who yet. Please let it be Han So-yul. That thought improved his mood a bit.
After classes ended and lunchtime rolled around, the four gathered at the main cafeteria. Eun-ho, Woo-hyun, Ye-rin, Seo-yeon. They usually ate lunch together. No one had decided it—it had just become routine. Eun-ho sat next to Ye-rin. Woo-hyun and Seo-yeon side by side across from them. He glanced at Ye-rin. Her face was close up: long eyelashes, cheeks slightly flushed. She looked perfectly normal. Hard to believe this was the face of a woman who'd fucked another guy last night. Ye-rin noticed his stare. She tilted her head slightly, then slipped her hand into his. Their usual move. Interlocking fingers under the table, a light squeeze. Eun-ho held it still for a moment, then slowly moved it. Onto her thigh. Ye-rin flinched. She looked at him with startled eyes, but he stared straight ahead. She tried to push his hand away. Her fingers gripped his knuckles, trying to lift, but he tensed and held firm. He leaned toward her a bit and whispered in her ear.
"Just a little... We haven't done it lately..."
The strength drained from her hand. She fidgeted with her lips for a second, then placed her own hand on the table. Eun-ho's hand began stroking her thigh slowly. Inside her skirt. Soft, warm skin against his palm. This used to be mine alone.Not anymore—my girlfriend's thigh. The thought hit, and his cock hardened. Instantly. It swelled rigid in his training pants. An emotion Eun-ho couldn't comprehend. Not betrayed anger, but excitement. Touching his woman, used by another man—it drove him wild. As his hand slid deeper into her thigh, he chatted with Woo-hyun.
"Eun-ho, your match is next week, right?"
"Yeah. Saturday."
"Let's all hang out after."
"Sounds good."
The conversation continued—nothing special. Match talk, training talk, condition talk. Everyday stuff. To an outsider, it was just typical sports uni students at lunch. Eun-ho's hand delved deeper, stroking the inside of her crotch. It was hot. Growing hotter. He could feel Ye-rin's breathing roughen beside him.
"Ye-rin, you okay? You look uncomfortable..."
Seo-yeon noticed first.
"No... It's just hot lately. Sometimes I get warm indoors. Maybe 'cause I'm on the swim team?"
Ye-rin forced a smile. Her voice trembled faintly, but Seo-yeon didn't seem to catch it. Eun-ho's fingers brushed her panty edge. He tugged the fabric aside slightly. Then slipped inside.
"Aheung!"
Ye-rin let out a sudden cry. Her chopsticks clattered onto her plate.
"Ye-rin, what's up? You're acting weird today..."
Seo-yeon asked again. Woo-hyun turned to look too.
"No, it's... hoo... It's fine..."
Her voice thinned. Eun-ho had shoved his fingers as deep as possible into her pussy. Hot, wet walls clenched tight around them. Already soaked. Woo-hyun's cock was in here yesterday. The thought made him thrust harder.
"You not eating?"
Focused on his left hand, he'd neglected his right—Woo-hyun pointed it out.
"Ah... Training's been intense. Food's not going down easy."
"That's when you gotta eat more..."
Seo-yeon replied with concern.
"Heut...Hut...Eung...Hoo..."
Ye-rin leaked soft moans. Head down, biting her lip, but she couldn't stifle them completely. Then she looked at Eun-ho and grabbed his arm with both hands. Her eyes were bloodshot.
"Uh... Looks like Ye-rin's not feeling well... I'll take her to the infirmary."
"Yeah, she doesn't look good..."
Seo-yeon nodded.
"Cool. See you later."
Eun-ho stood, half-supporting Ye-rin, barely touching his food. Her legs trembled faintly.
Eun-ho led Ye-rin to the staff men's restroom. Least crowded spot this time of day. At the end of the hall. Staff usually ate at their own cafeteria during lunch, so the area was empty.
"Eun-ho... Not today..."
Ye-rin spoke up inside. Avoiding his eyes.
"Why? We haven't done it lately."
"But... that..."
"It's fine. It'll be quick..."
He positioned her at the toilet. She gripped the seat lid with both hands and bent at the waist. Eun-ho hiked up her skirt and yanked down her panties. He realized this was the most turned on he'd been since their first time. Back then, Ye-rin hadn't been a virgin. But he'd never cared. It was trivial. Now, it gnawed at him. Knowing another man had been inside. That fact filled his head. And it was driving him insane. The more it bugged him, the more excited he got. He dropped his pants and pulled out his cock. Throbbing fully erect.
"Haaaang!"
He slammed into her pussy in one go. Tight enough, considering another guy had used it yesterday. Mine’s bigger, after all, Eun-ho thought. His reached depths Woo-hyun's couldn't. He started thrusting.
"Aang...Haang...Aang...Aang..."
Ye-rin moaned at a steady rhythm. Her fingers whitened on the lid. Eun-ho watched intently as his cock plunged in and out. Each thrust dragged her labia inward, then pulled them out on the withdraw.
"Haang...Aaaang... Uh... Eun-ho... Haang..."
"Feels good after so long?"
"Aaaang... So... so long? Eut... Ah!... Yeah, good..."
She questioned "so long." It probably hadn't been long for her. That reaction made his cock feel even bigger. He rammed harder.
"Aeut!! Haang...Ha-eung...Aang..."
And proof of last night's scene leaked from her pussy. Semen, bit by bit but unmistakable. Each deep thrust pushed out what lingered in her womb. He should have felt disgust. Instead, it was fiercer arousal.
"Ah... Ang...Aang... Hat... Hahat..."
Eun-ho sped up.
"Eun... Eun-ho... Haheung... You're... too... Eut... intense..."
"No time..."
Thud thud thud thud thud. Flesh slapped in the men's room. The sound amplified in the stall, probably leaking into the hall. Anyone entering would know they were fucking. Or passersby. But most would smirk and ignore it. Unless it was their girlfriend moaning.
"Haang... Haa... Eut...Aang... Eun-ho... You're... too... Aang... big... Hitting the end..."
The deepest part of Ye-rin's pussy. Her cervix entrance. The one spot only Eun-ho had claimed. His cock poked it relentlessly. This is mine. At least this deep.
"Haa... I'm... cumming..."
"A-eung... Ah... No... Not inside... today... Ha-eung... Outside..."
But Eun-ho had no intention of pulling out. Her womb already had cum in it—what was the point? He erupted deep inside.
"Eueuk...!!"
Semen blasted her cervix.
"Ah... Aeut... I said not inside..."
Ye-rin whined. But he stayed buried. His cock pulsed, squeezing out the last drop.
Eun-ho leaned down and kissed her. Smack... slurp... smack... smack... Tongues intertwined, echoing in the men's room. Her tongue wrapped softly around his. When they parted, she sighed.
"Eun-ho... Gotta clean up... Can't have it leaking out yet."
He got the gist, if not the details. Probably meant nude swimming or something. No leaks with a swimsuit.
"Where? Just do it here."
She shot him a sharp look.
"No way... What if someone comes in?"
"So? Just let 'em see."
Thwack. She smacked him.
"What?!"
She grabbed her bag and headed to the women's room. Eun-ho waited a bit, then followed. There she was, hose nozzle in her pussy. Water gushed out. Mixed with white fluid dripping to the floor. No cleaner, so rinsing in a pinch. He felt a twinge of guilt. Ye-rin startled at him.
"You scared me... Thought it was someone else... This is the women's room. Get out."
She stared at him, hose still inside. No real embarrassment. Since coming to this school, her sense of shame had dulled. Showing her boyfriend her pussy getting hosed out barely fazed her. Eun-ho stepped out. At least Woo-hyun's sperm seemed scraped clean. His cock had pushed some out; the hose handled the rest. He leaned against the hall wall, staring at the ceiling. His head had been a mess since last night. Rage, betrayal, tangled with inexplicable excitement. Holding Ye-rin felt like the most intense pleasure yet. Her body bearing another man's traces—it made his cock insane. This isn't normal. Eun-ho judged himself. But abnormal and stoppable were different things. He was a bit hungry. Hadn't eaten properly. But his mood wasn't bad.
