I applied a little of Ayoung’s vaginal fluid to her anus, but it still seemed a bit dry. The photographer seemed to agree and said,
“It’s still a little dry. Class President, could you make it wetter?”
“Easy.”
I brought the other finger—the one I’d just used to tease Ayoung’s pussy—straight to her anus.
The wetness coating my fingertip served as lubricant.
I began rubbing it leisurely in circles over the folds around Ayoung’s anus.
“Hngh…!”
When another person’s finger and the slippery liquid touched her, Ayoung’s shoulder flinched.
I did so carefully, as though I were touching something precious and lovely.
“Mmm….”
Ayoung’s lower body began to tremble faintly. Her usual icy, expressionless face was nowhere to be seen.
With her face buried in the mattress, Ayoung desperately held back the moan that threatened to escape.
The sight was incredibly arousing. I deliberately took my time, repeatedly pressing my finger against the entrance to her anus and then pulling it away.
“Haa… there….”
Unable to hold back any longer, Ayoung turned her head slightly toward me and whispered in a small voice.
“…Rub it in faster.”
Ayoung, usually so expressionless, was urging me on in a sultry voice. I felt a thrilling sense of conquest.
“All right.”
Grinning, I gently pushed the vaginal fluid remaining on my finger just inside her anal opening.
Ayoung’s anus gleamed with moisture.
Click.
The shutter went off at the perfect moment. The photographer said, looking satisfied,
“Good. Perfect. You can get dressed and leave now.”
Ayoung stood up without a word and got dressed. Her earlobes were still flushed red as she put on her clothes.
Ayoung left the multipurpose room without meeting my eyes once.
“Next.”
At the photographer’s voice, the door opened and my younger twin sister, Chaerin, entered.
“I guess you have to touch my body again.”
Chaerin spoke in a grumbling tone, but she couldn’t hide the faintly expectant look on her face.
“Which part are you going to photograph?”
“I want a full-body shot and a pussy shot.”
Chaerin answered the photographer and took off her clothes without hesitation. I’d seen her earlier, but she was still just as arousing this time.
Unlike in the bathroom, where she’d been wearing only a towel, she was now completely naked and utterly defenseless.
“All right, Class President. You know what to do, right?”
I nodded and approached Chaerin. Before taking the full-body photo, I had to make her nipples hard.
We stood directly facing each other, close enough to feel one another’s breath.
An awkward silence passed between Chaerin and me. Unlike with Ayoung, a strange excitement and shyness filled the air.
Chaerin seemed just as excited, her gaze wandering aimlessly as she tried to figure out where to look.
To break the awkwardness, I spoke first.
“Your breasts are pretty big.”
“W-what are you saying! They’ve… gotten bigger than when I was little, sure….”
Chaerin bristled when her twin brother suddenly brought up her breasts.
Her voice grew quieter and quieter.
I chuckled and reached out toward Chaerin’s breasts.
I’d touched women’s breasts several times just today, and I still wasn’t tired of it.
Could men in this world just not be into breasts like these?
As I kneaded her breasts to my heart’s content, my desire filling me, her nipples quickly stiffened and rose.
“They’re fully hard.”
“……”
I deliberately said it in a teasing tone and left my hand where it was.

Instead, I caught one of her raised nipples between my thumb and forefinger and gave it a light pinch.
“Hngh…!”
A small moan escaped Chaerin’s lips. Embarrassed, she covered her mouth with the back of her hand and turned her head away. But she didn’t tell me to stop touching her.
Rather, her body, twitching with pleasure, seemed to be asking for more. So I gently scratched around her areola with my fingernail.
“Mmm….”
Perhaps because she was embarrassed for the photographer to hear, Chaerin’s moan was muffled by the hand covering her mouth.
Clear vaginal fluid had already begun dripping onto the floor.
“All ready?”
At the photographer’s words, I reluctantly withdrew my hand.
Chaerin stood facing the camera with her face flushed red. Thanks to her stiffly erect nipples and the vaginal fluid running down her thighs, the photo came out extremely well.
“What’s the next shot? You said pussy earlier, right?”
At the photographer’s question, Chaerin seemed to hesitate for a moment, then shook her head.
“No. I’ll do my breasts.”
Then she looked at me and said,
“Hey. Your nipples still don’t seem hard enough, so… make them harder for me.”
Anyone hearing those words would have known she was seducing me.
I willingly approached Chaerin and touched her breasts again.
I grabbed and kneaded her tits even more boldly than before.
“You switched to your breasts because you wanted me to touch them more instead of photographing your pussy, right?”
At my whisper, Chaerin shook her head.
“N-no I didn’t…!”
But the puddle of vaginal fluid already forming on the floor contradicted her words.
Chaerin, who had been horny for a while, noticed the bulge rising at the front of my pants. Breathing hotly, she whispered,
“When we get home later… I’ll take care of you.”
Not long after she said that, the breast photo shoot ended. Chaerin got dressed and fled the multipurpose room as if running away.
Watching Chaerin’s butt as she left, I looked forward to the sexual service she’d give me today.
The other girls’ photo shoots continued after that.
Using my duties as class president as an excuse, I pretended to help them pose while freely fondling their breasts and pussies.
Naturally, not a single girl refused.
Even Baek Hayeon, who claimed to be a man, initially disliked it, but once I touched her clitoris, she twisted her body helplessly.
Hayeon’s clitoris would be especially glossy in the photo.
Before I knew it, the final turn had arrived.
“Next, Han Subin.”
Subin entered through the door and was as dazzling as ever.
She had glossy blonde hair she clearly took great care of, snow-white skin, and a shy smile.
Judging by her looks alone, she was unquestionably among the top three girls in the class.
Subin carefully took off her clothes.
Subin’s naked body was elegant and beautiful, like a high-end work of art.
The full-body photo went smoothly.
When I lightly touched her breasts, Subin grew tense but still made her nipples hard. The problem was what came next.
“I’ll do a face photo.”
I was flustered by Subin’s words. I’d wanted to touch her pussy under the pretext of helping her.
“I saw earlier that your pussy was pretty. Your face is pretty too, but how about taking a photo of your pussy?”
At my persuasion, Subin’s face brightened.
“Really…? I’m sorry, but I’ll take a pussy photo instead of a face photo.”
“Yeah. Good thinking.”
One compliment was enough to convince Subin.
Subin sat on the mattress and carefully spread her legs.
Full of anticipation, I reached for her pussy.
And once again, her reaction was similar to the one during the physical examination.
While the other girls got drenched from a single touch, Subin’s pussy slowly grew wet.
After dealing with girls who came too quickly, it felt like I was finally with a normal person.
As I kept touching her pussy, Subin bit her lip.
Her expression held both an apology to me and something like self-reproach.
“I’m sorry. I’m not getting wet easily again, so I’m only making things difficult for you…. I’ll just, I’ll just take a face photo.”
Seeing Subin look so sad made my heart ache. We were childhood friends, after all, and I wanted to help her somehow.
So I gently took Subin’s hand.
“No. I like you even more because you’re different from the other girls, Subin.”
“…Huh?”
Subin stared at me with her eyes opened wide. It seemed she hadn’t expected to hear words like that.
“You’re not making things difficult for me. You’re special because you’re different from the other girls.”
Subin’s expression changed subtly at my words. She murmured in a small voice, almost as if speaking to herself,
“As expected… you’re kind even after losing your memory….”
Then she looked up at me and said quietly, but with genuine feeling,
“Thank you….”
I smiled and stroked her hair.
“You’ve got a body this sexy, so be confident.”
After saying that, I lightly rubbed her clitoris. A different sound escaped Subin’s lips.
“Hngh…!”
I focused relentlessly on Subin’s clitoris. I rubbed it rapidly with my index and middle fingers, and her reaction grew stronger.
Subin clung tightly to me, affection in her eyes.
“Ah, uh, hngh….”
Subin’s climax was quieter than the other girls’.
Her pelvis rocked as vaginal fluid seeped out. But even that was lewd enough.
Vaginal fluid flowed from Subin’s pussy.
-Click.
The photographer didn’t miss that climactic moment.
“Thank you, Sihyeok. Thank you so much….”
Subin thanked me and left the multipurpose room.
Seeing the wet traces of vaginal fluid left behind where Subin had been, I was overcome by a strange feeling.
There was probably some past history between Subin and the original owner of this body.
Had one of them been nursing a one-sided crush?
I wanted to meet her alone later, ask her about it, and make a move on her.
Just when I thought all the girls were done, Teacher Iseol came in.
