Promise at the End
“Since it’s the last time... let’s not leave anything behind... Okay? Promise me. Today really is the last time.”
Having changed her mind, Seran threw herself into the caresses with surprising enthusiasm.
Unlike her husband, who had failed to react no matter how hard she tried to arouse him, Shin-woo’s cock trembled and even leaked a few tears at the slightest touch of her fingertips and tongue. It was as if it were thanking her for all the suffering it had endured. The thought brought tears to her eyes, and she barely managed to hold them back.
With the conviction that this was the last time, she decided she would do everything she knew for Shin-woo.
As she stroked his testicles and sucked on his cock, Seran lowered her head. Her hands moved beneath Shin-woo’s ass.
Thinking she was only trying to touch his butt, Shin-woo lifted his hips a little to make it easier for her hands to move.
But then a tingling sensation from a place he had not expected shot through his entire body and up to his head.
Seran stuck out her tongue and began to pleasure his anus.
Her tongue teased and licked at the twitching hole, poking it again and again.
Along with the sensation of having his cock sucked, a different kind of feeling spread through Shin-woo’s body, one he could hardly put into words.
All he could do was stare at the ceiling and barely hold himself back from lifting his hips.
After a long time spent working over his ass, Seran slid back up along his body as if she were gliding over him.
“D-did you like it? My husband likes it....”
“At a time like this, she’s talking about her husband....”
The fact that he was fucking another man’s woman made him even more aroused, but for some reason, hearing this woman mention another man left him with a strange, uncomfortable feeling.
Even while speaking, Seran never let her hands or tongue rest. The way she pumped his thick cock with one hand while circling his nipples with the tip of her tongue was not the work of someone trying this for the first time.
Shin-woo reached out and grabbed her ass.
Seran was barely 160 centimeters tall, a small frame, but thanks to her narrow waist, her hips and butt felt surprisingly large.
When he roughly squeezed the full handful of ass, he could feel her body twitch.
“You do dirty things like this for your husband too?”
“I-I do, but... my husband doesn’t really react....”
At the word husband, Shin-woo felt that same vague discomfort again.
He knew in his head that she belonged to someone else, but his male instinct was stirring up jealousy.
Shin-woo kneaded her ass and kept talking.
“You’ve got such a sexy wife, and he doesn’t even react....”
Their bodies, pressed tightly together, were slick with sweat and clung to each other as if they had no intention of separating.
“It’s because I’m not attractive....”
Her dejected voice was heartbreaking. And that heartbreak quickly turned into anger at her husband.
“No, ma’am, you’re plenty attractive. Especially this pussy. If it were me, I could cum inside it several times a day.”
The hand that had been gripping her ass shifted position and began to massage Seran’s sex.
“H-h-high schooler....”
Unable to hold back her excitement, Seran stopped caressing him and started writhing against his touch.
Thup.
“There’s no man who wouldn’t love a pussy that tight.”
One of Shin-woo’s fingers, slick with her juices, slid into Seran’s cunt.
“I could tell when I put my cock in, but even a finger makes it clamp down like this. What a filthy pussy.”
Every time those blunt, direct words came from Shin-woo’s mouth, he could feel her pussy tightening around his finger.
Shin-woo decided to play to Seran’s tastes.
“How did you manage to live while having such a dirty little pussy....”
As his finger began to move, Seran clung tightly to his body.
Her face, pressed against his collarbone, sent out hot breaths that heated his skin.
Haaah... haaah...
Each time his finger slid in and out, a long, breathlike moan spilled from her lips, mingling with the wet squelch of flesh.
She’s definitely narrow. No wonder she feels so good even with just one finger.
Shin-woo lifted his head and kissed her.
Chup, chup.
Slowly, gently, the two of them began by sucking at each other’s lips, and before long their mouths opened fully. Without either of them leading the way, their tongues mingled.
Maybe women with wet pussies really did salivate more too, because they had more than enough spit to keep the long kiss going without either mouth ever drying out.
Only after the kiss had gone on so long that their saliva stretched between them like sticky cobwebs did they finally break apart and naturally switch positions, taking up missionary.
Thwuk.
He drove all the way to the root in one thrust into the cunt loosened by his patient caresses, and Seran’s eyes closed as her mouth fell open.
“Mmm....”
The two of them froze for a moment, savoring the way her vaginal walls twitched and wrapped around his thick cock.
After that, they spent the whole night devouring each other’s bodies.
When Shin-woo opened his eyes to the morning sunlight, Seran was asleep in his arms.
Last night was really... incredible, no matter how I think about it. Still, there’s plenty I’m dissatisfied with....
Seran, whose only experience had been with her husband, wasn’t very skilled at sex.
Her awkward movements when she was on top of Shin-woo couldn’t help but be compared to Yumi’s, and in the end Shin-woo had to take over and finish things himself.
Still, Seran’s tight little pussy more than made up for the other shortcomings.
But what I liked most was... the feeling when I fucked her from behind. That tightness was really the best.
Just remembering how he had gripped her small, cute ass with both hands and drilled into her until it felt like she would split open sent a vigorous morning erection surging through him.
After gently laying the soundly sleeping Seran onto her side, he began to knead her breasts, feeling her nipples stiffen under his touch.
Is she waking up?
But Seran was still breathing softly in her sleep.
She gets aroused even while she’s asleep.
Carefully, Shin-woo bit one of her nipples.
The perfect breakfast.
“Mmm... h-high schooler....?”
“Ah, are you awake?”
Seran opened her eyes at the ticklish feeling spreading from her chest and the wet sucking sounds.
The first thing she saw when she woke was a robust young man sucking on her breasts, his cock standing straight up. Seran found the sight unbearably adorable.
“Again, first thing in the morning....”
Her body was still drowsy from sleep, and she could hardly get any strength into it.
“Just stay still, and I’ll take care of everything.”
Last night, the promise they had made about it being the final time no longer seemed to matter to either of them.
After sucking on her breasts and fondling her pussy with his hand a few times, Shin-woo saw the glistening slick coating his fingers and, without hesitation, brought his cock to her entrance.
Thwuk.
The sound that had filled Seran’s house all night began again.
“Ugh... maybe I overdid it.”
Even stretching, the soreness in his muscles wouldn’t go away.
By the time Shin-woo came to school after finishing breakfast at Seran’s house, the pain had finally caught up to him all over his body.
“Sex is great, but... maybe I need to work out more.”
Shin-woo was someone who exercised regularly, but lately he had begun to feel the limits of his stamina.
As he walked along, thinking, a poster caught his eye.
“Fitness club... new students welcome...?”
It was something he had never tried in his previous life, but he decided to throw himself at it boldly.
“Maybe I should check it out.”
“H-hello?”
Shin-woo’s university had all the clubs gathered in one annex building.
He found the room number listed on the poster and, hesitating, opened the door, only to be welcomed by nothing but a few pieces of exercise equipment sitting in an empty room.
“What... there’s no one here?”
Shin-woo stepped inside and started looking over the equipment.
“It’s a little old, but they seem to have everything they need.”
“Hey. Who’s there?”
A sharp voice reached the back of Shin-woo’s head just as he was lifting a dumbbell to inspect it.
Bang.
Startled, he dropped the dumbbell, and a woman who had rushed up from behind quickly checked the one that had fallen.
Whoa, that scared me.... But she checked the equipment before she checked the person.
He hadn’t exactly done the right thing by handling something in a place without an owner and without permission, so he was about to let it slide quietly when her piercing voice cut into his ears.
“Excuse me! You almost hurt my cutie!”
“Yo-your cutie...?”
She cradled the dumbbell in her arms as tenderly as if it were a baby, glaring at Shin-woo with eyes that looked ready to devour him.
“T-the dumbbell... is your cutie...?”
The standing woman’s eye level was not much different from Shin-woo’s.
Wow, she’s really tall.
Compared to Shin-woo, who barely reached 180 centimeters, she was easily over 170 centimeters, and she stepped right up to him, eyes wide open and fixed on his face.
“What exactly were you doing in here? Don’t tell me you were trying to steal my cuties....”
Like a bull snorting hot breath, she radiated a fierce energy that made Shin-woo flinch and step back.
“No, that’s not it....”
Shin-woo pointed at the club recruitment poster stuck to the wall.
Following the direction of his finger, she glanced at the poster, then quickly turned back to meet his eyes.
The fiery look from a moment ago had vanished. Blinking her large eyes, she carefully set the dumbbell down and grabbed Shin-woo’s hand.
Her face is pretty decent.
Setting aside the bad first impression, she was the kind of woman whose tall figure and bright, striking features would make her stand out at a glance.
“You’re here to join our club? Oh, you should’ve said so from the start.”
Shin-woo’s two hands were caught in hers as she shook them enthusiastically.
“C-could you let go of my hand....”
Noticing his still-bemused expression, she seemed to realize her mistake and straightened her shoulders into a proper posture.
“Let me introduce myself properly. My name is Seong Su-ji. I’m the president of this fitness club. Please take care of me from here on out.”
“Huh? I haven’t said I’m joining yet....”
Without hearing him, Su-ji began introducing the club room in an excited voice.
At that moment, Shin-woo had no idea that he and Su-ji would become entangled.
Because the Grim Reaper’s screen hadn’t shown Su-ji’s face.
But Shin-woo’s expectations were already starting to go off course.
