The Massage Tutor
Actually, there was one more place I wanted to get a massage. The sensation of Nayeon’s bare breasts was still vividly imprinted on both of my hands. Her skin felt soft and youthful, slightly sticky from a light sheen of sweat. Perhaps because her body temperature was a bit high, she felt warm all over. Soon, Nayeon slowly sat up on top of me, facing me. She pouted her lips and stared down, watching with a blank expression as my hands kneaded her breasts.
"Haa, haa..." My penis, right on the verge of ejaculation, was leaking pre-cum that clung to it like magma oozing from a volcanic crater. Nayeon looked down at my throbbing member, which was twitching right in front of her crotch. She gulped, then slowly lifted her eyes to give me a sly grin. "....Heh, does my chest turn you on that much, Teach?"
"Ugh...."
"...I asked if my chest turns you on, you f*cking bastard..."
As she grabbed my sticky, throbbing penis and rubbed it up and down with a rhythmic thwack-thwack-thwack, I couldn't hold it back any longer. I erupted, spraying my semen everywhere. Once again, my hands instinctively clamped down hard on her bare breasts at the moment of climax. Nayeon winced, letting out a low moan.
"Haa-ugh....!"
As I thrust my hips, shooting out jets of semen, my hands trembled as I squeezed her breasts with all my might. Nayeon bit her lip hard, her eyes squeezed shut, shivering as she endured the pain of her sensitive mammary glands being crushed without mercy. A few minutes later, when the ejaculation finally ceased, I snapped out of my trance and hurriedly pulled my hands away in a panic.
"Haa, haa, haa...!"
Only then did I realize what I had done, and a chill ran down my spine. My thick semen was splattered across her upper body, from her navel all the way up to her cleavage, dripping down in long streaks. Furthermore, perhaps because I had squeezed too hard, her immature breasts were swollen and red, looking almost bruised. I squeezed my eyes shut and trembled, convinced that this time, Nayeon would surely kill me. But when I cautiously peeked through my eyelids, Nayeon was looking at me with her eyes curved into crescent moons, feigning a clumsy sense of composure.
".....You idiot, did it feel that good?"
"E-eeh...."
I stammered, hesitating, before giving a small nod. Nayeon blushed shyly and smiled with satisfaction. Suddenly, she reached behind her, grabbed a box of tissues, and held it out to me, acting all haughty. "Here, you clean it up."
"O-okay..."
I pulled out three or four tissues and wiped the semen off her upper body. Since the fluid was dripping downward due to gravity, it was easier to wipe upward, but in the process, my hands kept brushing against her soft, squishy breasts. Every time my hand touched the swollen, bruised areas, she let out a small moan, as if even a light graze was stinging.
"Ouch..."
"I-I'm sorry...! Should I stop?"
As I trembled and fumbled, Nayeon glared at me and said in a menacing tone, "....Shut your mouth and keep wiping."
"O-okay...."
Only after I had meticulously wiped away every drop of semen from between her breasts did Nayeon finally move off me and put back on the t-shirt she had discarded. She reached behind her head to fix her hair and muttered to me, "If you tell the others, you're dead."
"O-okay...."
For the rest of the tutoring session, she just leaned against my shoulder, lazing around and playing on her phone.
When I trudged home, the light in my younger sister's room was on, which was unusual, but she didn't come out to greet me. Worried that something might be wrong, I quietly opened the door and peeked inside. Sure enough, she was slumped over her desk, fast asleep from exhaustion. It looked like she had been studying hard until just moments ago, as all sorts of reference books were scattered messily across the desk. As I gently stroked her hair, she muttered in her sleep, "Mm...? Oppa...? When did you get here?"
"Mm, just now...."
Waking up late to my touch, she rubbed her eyes and lifted her messy head. She immediately threw her arms around me and nuzzled her face into my chest. "You're tired, aren't you, Hyun-jung? Should I massage your shoulders?"
"Really? Hehe... I'd love that."
I tenderly massaged the shoulders and neck of my sister, who had been working hard studying until late at night. She didn't have the best posture, so her muscles were often knotted up, and I frequently gave her massages. She completely surrendered her body to my touch, her head bobbing like a broken doll every time I kneaded a knot.
"Haa... Ah, that feels so good, Oppa.... Haa-ugh.... Ah...."
"D-don't make weird noises."
I scolded her gently and continued to massage her for a few more minutes. Finally, she let out a satisfied sigh, grabbed my hand, and said with a bright expression, "Phew, thanks, Oppa. I feel like I'm alive again.... Now I just need to study a little more and then I can sleep!"
"Yeah, don't overdo it."
She waved at me with a bright smile, and I waved back with a smile of my own before leaving the room. I returned to my own room, sat on the edge of the bed, and let out a long sigh. "...Phew...."
The sensation of Nayeon’s warm, bare breasts was still vivid in both my hands. I stared blankly at my hands for a moment, then shook my head and buried my face in them.
The next day.
By now, I could guess who was at Nayeon's house just from the entryway. I could distinguish who was in the room even before I went in, based on their unique presence. When I cautiously opened Nayeon's door, just as I had expected, Ye-eun was lying on the bed with her chest pressed against it, lazing around and looking at her phone. I thought to myself that I was lucky and let out a secret sigh of relief. If I had to choose the one among the three who made me feel most at ease when we were alone, it was Ye-eun.
Ye-eun certainly wasn't a delinquent with a naturally foul personality like Nayeon, nor did she have an unpredictable, four-dimensional mental world like Seung-hee. Her way of speaking was soft, and she always had a languid, gentle smile on her face, so sometimes I even mistook her for being a kind person. Of course, once we started doing anything lewd, she would reveal her true colors and torment me more persistently than anyone else using the most perverted methods imaginable... but in other words, it meant she was the most normal of the three when we weren't doing anything sexual.
I gave Ye-eun an awkward smile and greeted her cautiously. "Hi, Ye-eun.... Have you been well...?"
"....Get lost. I'm in a f*cking bad mood, so don't talk to me, you little shit."
I was so shocked that my jaw dropped, and I froze stiff on the spot. Looking closely, unlike usual, she wasn't smiling with those languid eyes framed by long eyelashes. Seeing that sharp, actress-like face wearing such a cold, blunt expression created an immense sense of pressure that was completely different from her usual self. My feet were rooted to the spot, and my legs trembled. Ye-eun didn't care whether I was there or not; she just frowned, crossed her legs, and kept staring at her phone. I even started to suspect that someone who looked exactly like Ye-eun had come in her place. But while the atmosphere she exuded had changed, her appearance was identical to the Ye-eun I remembered, so that possibility seemed extremely low.
I trembled like an aspen leaf and sat down quietly in front of the table, trying not to make a sound. Then, suddenly, Ye-eun grabbed her own neck, kneading it with a dissatisfied expression, and muttered, "...Ha, f*ck, it's throbbing like hell..."
As she said that, she punched her own shoulder a few times, her face twisted in a fierce scowl. Seeing that, something clicked, and I hesitated, looking at her with the air of someone who had something to say. Finally, unable to take it anymore, Ye-eun turned her gaze from her phone, glared at me, and snapped, "F*ck, why do you keep staring? You got something to say?"
"W-well... your shoulders look really knotted up, so I was thinking maybe I could give you a massage..."
I muttered timidly in a voice that was barely a whisper, my nerves frayed. Ye-eun snorted and said with a mocking laugh, "A massage...? Did you just say massage?"
"Y-yeah..."
"Ha, have you even ever given a massage, you little runt?"
"...A-a little..."
Ye-eun narrowed her eyes and scanned me up and down for a long time in a way that made me feel uncomfortable, then turned her head away gruffly, stared back at her phone, and muttered under her breath, "...Then go ahead and try. If you hurt me, I'll kill you."
"O-okay..."
I crawled slowly on my knees and approached from behind Ye-eun. Ye-eun glanced back at me once, then gathered her voluminous hair with her hands and let it fall in front of her chest. Her porcelain-white nape was covered in fine, soft baby hairs, making her look less like a human and more like a cat. I gulped and started to massage her just as I had done for my sister. And about five minutes later.
"Ugh..... Ugh.... Haa, haa.... This is amazing, Teach...? Where on earth did you learn to do this?"
Ye-eun had returned to her languid expression, smiling pleasantly as she muttered. Encouraged by her reaction, I put more strength into my hands and pressed down firmly. Usually, when ordinary men give massages, they use too much force and it ends up hurting, but since I was born with a frail constitution, there was no such worry. It seemed that as long as I put all my effort into kneading, most people found it refreshing. Soon, as I tapped and loosened her muscles with my fists, Ye-eun let out low moans and wore a blissful smile.
"....Huuu...."
"...How is it? Is it a bit better...?"
When I asked with an awkward smile, Ye-eun slowly opened her eyes, looked back at me, and offered a soft smile for a moment. But for some reason, that smile slowly morphed into a sinister expression, and I felt a sudden surge of anxiety, gulping down a dry swallow. Then, Ye-eun suddenly turned her body toward me, lifted both arms to show off her armpits, and swept her hair back as far as it would go, muttering in a cute tone, "...Teach~ Actually, there's one more place I want a massage~"
"Uh...? O-okay..."
"Turn around for a second, Teach~"
As I turned around cautiously, trembling with anxiety, I suddenly heard the click of a bra hook being undone behind my back.
