Cha Eun-jung's Devoted Anal Service
"Haaauu... Ah, haah♡ Haaaak...♡"
Warm, plush lips planted affectionate kisses across firm skin with soft smacks, or—if they could fit the flesh between them—sucked with wet, rhythmic chuu chuu sounds. Moist, slippery tongues licked every hidden crevice as though cleaning it thoroughly. The girls of Class 1-A devoted themselves with nothing but their mouths and tongues, offering sincere, wholehearted service.
Wherever their lips touched, a ticklish yet electrifying sensation bloomed and raced across Lee Seon-ah's body. It never quite pushed her over the edge... yet the constant, insidious pleasure made climax feel like the wiser choice.
Nestled against Seong Mi-na's pillowy breasts, eyes glazed, Seon-ah savored the girls' full-body nude service and let out sweet, trembling moans.
"...Gulp."
Seon-ah's gaze landed on Cha Eun-jung, who sat obediently between her widely spread legs, staring intently. But the focus wasn't quite where she expected. At that height... that's not my pussy. That's my anus.
Wondering what she was planning, Seon-ah kept her eyes locked on her even as her hips twitched from the rising pleasure. Sensing the stare, Cha Eun-jung glanced up, then slowly lowered her upper body between Seon-ah's thighs until she was lying prone.
Her chest nearly touched the floor while her hips lifted high—an arched, cat-like stretch. In that pose, Cha Eun-jung bit her lower lip hard and focused on the sight before her.
Through the tightly closed folds of Seon-ah's pussy, pooled nectar pushed outward in a slow, glistening trickle. It slid downward, past the perineum, and gently soaked the twitching pink pucker of her anus.
"Haa..."
Staring at the perfectly smooth, hairless ring—just as flawless as her pussy—Cha Eun-jung fell into another wave of inner conflict. Seon-ah performed frequent enemas and kept herself meticulously clean so she could offer anal sex whenever asked, yet it was still a place most people would instinctively consider dirty.
Do I really need to go this far? The question warred with the certainty that this was the only way to atone for the sins she had committed against Seon-ah. Before long, the scale tipped toward atonement.
If I truly want to serve her and heal her, I have to be capable of even this.
Cha Eun-jung swallowed dryly, then crawled forward with a look of grim resolve. Overcoming her body's instinctive revulsion, she brought her face close enough to feel the heat radiating from the glistening pink anus. Her heart hammered wildly. Finally, she squeezed her eyes shut and pressed her lips forward.
"Huu, huu... Heuup..."
Seon-ah's anus had been twitching violently at the feel of approaching breath. Cha Eun-jung's soft lips pressed firmly against it, then pulled away with a sweet chu sound. At that exact moment, an overwhelmingly new and intense wave of pleasure surged from her rear, making Seon-ah's hips buck sharply upward.
"Ungh―――♡"
Cha Eun-jung let out a short, shaky sigh as a tingling electric current raced down her spine. The immorality of kissing a place that should never be kissed. The depravity of pressing her lips—lips countless men outside these walls would kill to possess—against an anus with an audible chu. The shame of doing so willingly in front of the girls of her class, girls who looked up to her with admiration. The utter collapse of the refined status she had spent years cultivating as a woman, all destroyed by a single kiss.
All of it pierced her vertically, sending tingling sensations all the way to her fingertips and toes before rushing up her neck and scrambling her mind. The humiliating, masochistic thrill of deliberately ruining herself for the first time in her life flooded her head. Like a child discovering masturbation, Cha Eun-jung grew more aroused than she had ever been in her life. She dove back in, pressing against Seon-ah's twitching anus once more.
"Chu, mnh... Chu, chu, chuuup, haah...♡ Chuuup, chuuuuup...♡"
What began as brief, repeated pecks gradually lengthened into lingering rubs. Without realizing it, Cha Eun-jung's own virgin pussy dripped long, clear strands onto the floor. Her pale buttocks swayed gently side to side as she devoted herself to kissing the twitching ring with fervent passion.
"Eung, Eun-jung, haaaat...♡ What, what are you d-doing—ungh, heuuup♡♡"
Seon-ah, receiving those wet, repeated kisses directly on her anus, could barely stay sane. The shame of having her pleasure-twitched rear exposed so obscenely to her best friend—and of being kissed there—merged with a completely new sensation. Unlike the feeling of fingers or toys, this was moist, lewd, and so spine-tingling that goosebumps erupted across her nape.
She tried to twist her hips to discourage Cha Eun-jung, but the other girl only gripped her thighs with both arms and pressed her lips even more firmly against her.
"Ahup, ah, haaaak―♡ Eunng, ah, haak...♡ Hak♡ Haak♡ Haaaak♡"
Each wet kiss against her anus made her hips bounce helplessly. The tingling pleasure raced up her back so intensely that her sweat-slick lower belly heaved. And it wasn't just the physical sensation. The knowledge that Cha Eun-jung—her friend, the precious youngest daughter of a chaebol family—was earnestly kissing and even gently sucking her most forbidden place filled her with overwhelming immorality and a strange, intoxicating sense of conquest.
The girls of the academy, especially those from Class 1-A where the protagonist belonged... even if they weren't main heroines, every one of them possessed breathtaking beauty. And right now those same girls were clinging to her naked body, using their lovely lips and tongues to lick and suck every inch of her skin in devoted service.
Seon-ah's mind went completely white. The pleasure was so intense she feared her nerves might burn out. Sharp cries—whether screams or honeyed moans, she could no longer tell—kept spilling from her lips.
"Hehe..."
Seong Mi-na gazed down at her flushed face with a warm, satisfied smile and gently brushed the disheveled hair from between her large breasts.
"Seon-ah, how does it feel when your friends serve you like this? Does it feel good?"
"Hauu... Ung, uung♡ Geut...♡ I-it feels so gooood...♡ Ah, haaaak♡"
When the teacher asked in her soft, quiet voice, the broken little sounds of "Ah♡ Ah♡" finally formed a short, trembling reply.
"Let's keep working hard so you can learn that this gentle pleasure is far better than the violent kind you used to crave, alright?"
The girls whose jaws and mouths had begun to ache from the long service traded places with the waiting group, who had been lightly touching themselves in anticipation. Even so, Cha Eun-jung remained in position with an ecstatic expression, still diligently kissing Seon-ah's anus. Watching her, Seong Mi-na felt a spark of hope that the girl's extreme masochistic tendencies might improve faster than expected.
Still... I really want to masturbate so badly right now. I probably shouldn't, right?
Lee Seon-ah's Side
"Auuu... My tongue feels like it's going to fall off..."
"Teacher, we're doing this again tomorrow, right? I didn't get a turn today!"
"Do you think this blanket will dry by tomorrow? I don't have a dryer at home..."
Service Time ended along with club activity hours, and it was finally time to head home. The girls chattered away as usual while packing their bags. I forced my thoroughly languid body to move, slung my bag over my shoulder, and stood up—only to find Eun-jung already finished and standing beside me, one hand delicately covering her mouth.
"Ah, um... Hi. You're heading home now...?"
"Uh, yeah..."
Both of us had bright red faces and kept stumbling over our words. Seriously. If you're going to be this embarrassed, why did you do it in the first place? Every time those lips touched me, my whole body broke out in goosebumps and it felt incredibly good, but... it was also unbelievably humiliating.
"Then... can I come over to your house today?"
Her voice was barely above a whisper. She kept glancing at her feet, then at my face, then back to her feet. I nodded without hesitation.
After growing distant from Han-na, being alone with Eun-jung always made me painfully aware of the empty space she had left behind. There was still a lingering resentment toward the girl who had caused all of this, so things had felt awkward. Until a few days ago, we had barely even looked at each other.
But the "service" Eun-jung had shown me today completely melted away every last barrier I had unconsciously kept between us.
"Why are you still covering your mouth like that?"
"Ah, it's nothing... It might be dirty. If it smells or anything..."
"Let me see."
"N-no! It's too embarrassing...!"
When I reached out to move her hand, she panicked and jerked backward. Before she started servicing my anus she had hesitated and flinched, but once she began she pressed her lips against me so eagerly. Now that it was over, her pure face was flushed crimson with shame.
The sight stirred something mischievous in me and I wanted to tease her a little more, but if she started crying it would only make things harder for me.
"Fine. Let's just head home quickly. Did you let your family know?"
"Ah, yes... I told them I was sleeping over at a friend's house."
"..."
Whether she realized how obvious she was being or not, Eun-jung was openly advertising that she intended to have sex with me. In the end, I walked home side by side with the girl who stubbornly kept one hand pressed over her mouth the entire way.
...She isn't planning to do that again once we get home, is she?
