The Sensitive Nipple, Just Like a Girl
"Oh my~ Mr. Jihwan, did you sleep well? I’m so sorry to call you so early in the morning~"
"Ah, no, not at all... Is something the matter?"
I answered, my hands trembling as I held the phone early in the morning. Ever since what happened with Na-yeon yesterday, I had been living in constant fear, and I felt like the moment I had been dreading had finally arrived.
'Did Na-yeon tell her everything? Well, it makes sense... After what she did to me, I deserve to go to prison...'
I waited for Na-yeon's mother to continue, feeling half-resigned to my fate.
But instead, Na-yeon's mother began to speak in a bright, cheerful voice, saying things I never expected.
"You see~ as you saw yourself, our girl is a bit shy around strangers~ She usually hates meeting new people, which is why we've changed tutors so many times until now~"
"But for some reason, Na-yeon seems to really like you, Mr. Jihwan! It’s so rare—she hasn't complained even once, and when I asked her, she kept saying she wanted to keep doing the tutoring~"
"How did you manage to win her over like that, Teacher~? What’s your secret? Ho ho ho!"
"Oh... Th-thank you..."
After that, Na-yeon's mother rattled on with various complaints and endless praise for me before suddenly hanging up, saying she had just arrived at her office.
I put the phone down and checked the clock; nearly an hour had passed since I first picked up the call.
I flopped onto my bed in my sweat-drenched pajamas. It still didn't feel real, so I stared blankly at the dim ceiling for a long time.
'...Na-yeon likes me that much...? She said she wanted to keep doing the tutoring...? Even after what happened yesterday...? What on earth is this...'
Of course, I could guess what kind of conversation had actually taken place.
It wasn't that she had genuinely told her mother she liked me; it was almost certainly the result of her mother's barrage of questions like, 'How is the tutor, is he okay?', or 'Should we keep going with this teacher?', to which Na-yeon had likely just nodded absentmindedly without even looking up.
But even that was a shocking enough reaction for me.
I remembered the scene of Na-yeon staring at me, her hands and face completely covered in my semen, and I felt my penis starting to stir with excitement again.
"...So, she wasn't angry at that time...? Why on earth..."
I was in a state of extreme confusion, burying my face in my pillow and pulling at my hair.
"Oppa, I made food, so come out and eat!"
Just then, my younger sister, who lived with me, threw my door open, spoke affectionately, and turned back around with a light step.
I sighed as I stood up shakily from the bed. That was when I saw a text message from Na-yeon's mother on my phone.
Please just enter the door code when you arrive~
The password is *****
I scratched my head in bewilderment.
'...No, giving the door code of her house to a tutor she met for the first time yesterday? Does this make any sense...? Just how harmless of a person does she think I am...?'
Of course, it was a good thing that she didn't view me as a threat, but it also made me feel a bit uneasy, as if she didn't even consider me a man at all.
I grumbled to myself as I headed to the living room to eat the meal my sister had prepared.
That evening, I found myself standing in front of Na-yeon's door once again.
I swallowed hard and slowly reached toward the door lock.
I thought about just ringing the doorbell and having someone inside open it, but then I realized that given Na-yeon's personality, she would never come out to open the door herself, no matter how many times I rang.
Na-yeon's mother must have known that, which is why she gave me the code.
I had no choice but to punch in the numbers myself and let myself in.
"Ahem, ahem..."
I tried my best to forget what happened with Na-yeon the previous day and put on the most dignified expression I could muster.
However, there was no sign of life inside. For a moment, I panicked, wondering if I was all alone in an empty house.
I carefully crept toward Na-yeon's room and peeked inside. It was still a mess, with cosmetics, tissues, and clothes scattered everywhere.
Fortunately, upon closer inspection, there was someone inside. But it wasn't the daughter of the house.
A girl, much taller than Na-yeon and with a far more mature appearance, had completely taken over Na-yeon's bed as if it were her own, lying face down and snoring away.
I entered the room as quietly as possible. The scent of a girl, which I had smelled the day before, seemed to linger even more strongly here.
"Snore... hnn... slurp... smacking lips."
...The students I was tutoring were three in total. Excluding Na-yeon, the other two were Ye-eun and Seung-hee.
When I was given the description, I heard that the tall one was Ye-eun, so it was highly likely that this was her.
I hadn't met the last one yet, but I doubted there was anyone taller than this girl.
"...E-excuse me..."
I tried to shake the girl, who was buried deep in Na-yeon's pillow, awake. Ye-eun had wavy, brownish hair.
Her hair was so thick, coarse, and dense that it looked like a lion's mane. Above all, the size of her breasts, which were pressed flat like steamed buns against the bedsheets and spread out to the sides, was enormous.
Her pelvis was wide, and her limbs were long like a model's; honestly, if she weren't wearing a school uniform, I would have easily believed she was older than me.
Just then, Ye-eun tossed and turned in her sleep and rolled her head toward me, allowing me to see her face clearly for the first time.
Ye-eun had long eyelashes, thick eyebrows, and incredibly distinct features.
If Na-yeon had an idol-like, pretty face, Ye-eun looked like a movie star. She must have been scouted on the streets quite often since she was young.
Under normal circumstances, this was a face I would only see on a screen, not in a messy bedroom corner.
...Since someone with such superior looks was Na-yeon's best friend, it was highly probable that she was a delinquent, too.
I remembered a girl who looked exactly like this who had persistently sexually harassed and bullied me in the past, so I couldn't help but shudder with fear.
I was terrified before I even spoke to her, but I carefully grabbed Ye-eun's shoulder and shook it.
"E-excuse me..."
After shaking her for a while, Ye-eun's eyelids finally fluttered open slowly.
I swallowed hard, feeling incredibly tense, and whispered almost inaudibly.
"Y-you're Ye-eun, right...?"
"....Mmm..."
Ye-eun made a cute sound that didn't quite match her image, then flashed a bashful smile, tilted her head to let her hair fall, and looked at me through half-closed eyes.
Seeing a tall, beautiful girl lying there in the sunlight made it look like a scene from a magazine, even though she hadn't done anything.
Ye-eun's eyes were still half-closed as if she were sleepy. She stared intently at me, frozen in place, and then suddenly reached out and grabbed my wrist.
"Oh...? Y-Ye-eun...?"
Without a word, Ye-eun pulled me into her embrace. She was stronger than me, and my frail arms couldn't even put up a fight.
Before I knew it, I was trapped between her arms and legs, unable to move, just like a teddy bear she was cuddling to sleep.
'...W-what, what is this situation...'
"....Mmm...."
I hadn't noticed because she was covered by the blanket earlier, but it turned out Ye-eun had kicked off her school skirt while sleeping.
In other words, she was wrapping her bare legs, clad only in thin panties, around me and holding me tight. My heart was pounding so hard I couldn't find any way to calm down.
Ye-eun looked down at me with sleepy eyes and muttered faintly.
"...You're really cute... You're so small, just like a doll, hehe..."
With that, she pulled me tight like a bolster and drifted back into a comfortable sleep. The soft, supple skin of her inner thigh was pressing heavily against my waist.
"W-wait... that..."
Just then, Ye-eun's hands, which were wrapped around my upper body, began to crawl inside the shirt I was wearing, and she started to tickle and tease my nipples with her fingertips.
"Hick... ugh..."
I flinched at the sensation of my sensitive nipples being teased. Even if I wanted to resist, my limbs were firmly pinned, and I couldn't move an inch.
From both nipples, a strange, electric shiver spread through my entire body,
