Four Times, No Breaks
The words “I can do it four times with Seo-yoon too, I’ll fuck you like a dog” were clearly no empty promise. Mari began moving her hips. Unlike usual, she gave no time for adjustment; the moment her thick cock filled my pussy completely, she started thrusting hard, making the soft walls convulse on their own.
Normally she would slide in and stay still for about a minute, letting my pussy calm down and get used to the size. “Hngh, too—too fast…!” Today, however, Mari pounded into me without mercy. If I hadn’t already been dripping wet, the pain would have overwhelmed the pleasure. Plap, plap, plap—! The wet sound of our bodies colliding echoed through the room. Her vicious cock moved so fast it scrambled my insides; keeping my head clear was nearly impossible.
If my hands had been free I could have tried to match her pace or grabbed her to slow her down, but the ribbon around my wrists showed no sign of loosening. I might have been able to break it if I focused all my strength, yet the relentless thrusts battering my pussy made concentration impossible.
Squelch, squelch, squelch—! As if sensing my thoughts, my pussy—already swollen and sensitive—clamped down greedily around the cock that had finally entered it. “I think this pace is just right for me right now,” Mari grinned from above me. At first she had looked ready to cum the second she put it in, but now she was thrusting like she had all the time in the world, casually brushing her hair back.
“Hnn, ah…♡♡♡” Maybe the hair she had grown for two months kept falling into her eyes; with practiced ease she tied it up and reached for me. “Your hair looks really good on you right now, Seo-yoon.” “Haa, haah♡ Is that—really important right now…?” “Of course it is.”
The moment she answered, she snapped her hips upward with sudden force.

“Oohk…♡ Ooooh, hnn, hngh…♡♡♡” When the thick head of her cock pressed firmly against my cervix, a raw, animal sound tore from my throat. I slapped a hand over my mouth in shock—embarrassed that such an unladylike noise had come out of me—but it still leaked between my fingers. The cervix wasn’t something you could train or get used to by touching it often; the sensation was simply too intense to endure.
“I didn’t know you’d like it this much. Should I do it more often from now on?” “No… This time—only this once…♡” “Hmm… really? Here, Seo-yoon, give me your hands.” “My hands…?”
She slowed down a little, moving more gently like usual, and I finally had enough leeway to move. Following her instruction, I held out both hands still bound by the ribbon. Mari took them and placed them on my lower belly. “W-what are you trying to do…?” “You’ll see.”
With a sharp thrust she drove upward again. The cock that had been kissing my cervix now pushed it from below, making my stomach visibly bulge. “Haaah, haaaah…♡” Pleasure like lightning struck my brain. My mouth fell open on its own as electric tingles raced through me. While I was still dazed, Mari leaned down, licked the strand of drool from my parted lips, and pressed my hands harder against my belly.
With her cock pushing up from inside and my own hands pressing down from outside, my cervix was squeezed between both sides. “…!!!” “I thought your cervix was pretty sensitive… How does it feel?” The dual stimulation made my consciousness cut out for a second. When I came to, my body was shaking uncontrollably, squirting all over Mari while she kept thrusting. Splurt, spurt—! Her stomach and cock were already soaked with my fluids.
“Seo-yoon, can you hear me?” “Hee, heehee…♡” My whole body felt loose and floaty. The pleasure and happiness were so overwhelming that I almost wished the sensation would never end. ‘Ah, so this is what a real orgasm feels like.’ The moment the realization hit, my mind snapped back into focus and every sensation flooded in at once. The sudden overload of pleasure made my brain stall.
“Ah…” That was the only word I could manage. Too much input at once froze my thoughts completely. Once my brain finished processing the avalanche of stimuli— “Hnnngaaaah♡♡♡ Haaah—!!!” My body finally reacted to the second massive orgasm, trembling violently. Mari hugged me tightly and whispered in my ear. “I’m right here. You can cum as much as you want.” “Y-your voice… too close♡”
Every inch of my skin was already hypersensitive; feeling her bare skin against mine was pleasurable enough, but having her sweet voice whispering right against my ear made my head burn. I felt like steam was about to pour out of my skull, yet my pleasure-drunk body refused to move. All I could do was rest my chin on her shoulder, feel the soft press of her breasts against mine, and keep cumming.
“You like it when I whisper like this too, huh?” “Hyaaaah♡♡♡” When she pressed her lips to my ear and spoke in a wet, breathy voice, a shiver raced down my spine. Splurt, spurt—! My pussy fluttered and gushed again, clenching tightly around the cock buried deep inside. Mari seemed to reach her limit as well; I could feel her shaft swell even thicker, preparing to cum.
“Hnn—!” She sealed our lips together at the same time her cock began pounding the sensitive spot inside me, pumping thick loads of semen while grinding as deep as she could. Glurt, glurt, glurt—! Even through the condom I could vividly feel the hot cum flooding into me. Or maybe it was my own body that was burning up; I couldn’t tell anymore. We were pressed so tightly together that our sweat-slick skin stuck wherever we touched.
“Haa… You’re squeezing me even harder than usual.” Slurp, pop—! After finishing, Mari carefully pulled out while holding the base of the condom so nothing would spill. The rubber was swollen to the point of looking like a water balloon, swaying heavily. “Hee, heehee…♡” Still riding the aftershocks, I watched her tie off the used condom and immediately reach for a new one. “…Huh?” “I told you. I’m going to fuck you like a dog today.”
A genuine sense of danger washed over me. If this kept up I might actually die from pleasure overload. My brain felt like it was melting; at this rate I’d spend the whole day thinking about nothing but sex. I tried to escape. “Hiiiik…!” I crawled away on all fours, but with my hands tied and my hips still weak from the previous position, my body wouldn’t obey. A short rest might have helped, but right now there was no time for rest.
“Where do you think you’re going? We still have two more rounds.” “No, I’ll die…! I’m seriously going to die!” My throat was dry from all the sweating. I swallowed hard, and Mari’s eyes lit up. She grabbed the water bottle beside the bed, took a big gulp herself, then filled her mouth and leaned down to kiss me. “Mmph—!” Gulp, gulp— I had no choice but to drink the lukewarm water she pushed into my mouth. Only after I’d swallowed everything did she release my lips. “Pwah—!!! I thought I was going to suffocate…!”
While I was still gasping for air, Mari was already on top of me again, hands on my shoulders. “Ah.” I should have used that moment to get off the bed… She grabbed the ribbon binding my wrists and lifted my arms straight up. With my hands pinned above my head, she buried her face between my breasts and licked the sweat from my skin. “Hiiih, what are you doing…!” “Tasting Seo-yoon?”
She licked not only my chest but my stomach, armpits, and collarbones—every embarrassing spot—then licked her lips with satisfaction. Her glowing blue eyes looked exactly like a predator’s.

“Hnnk, hngh…♡♡♡” “Mm, did I go too far?” Gulp, gulp. After emptying an entire bottle of water, Mari looked down at me and muttered. The final doggy-style round must have been the finishing blow; Seo-yoon lay there with unfocused, glassy eyes, looking like she had passed out while awake. The condom was still stuck inside her pussy because she was clenching so tightly. Even now her cunt kept twitching and squirting, and her twitching asshole was visible too.
At least the condom wasn’t leaking thanks to how hard she was squeezing. Drool still trickled from her slack, open mouth. They had gone four rounds instead of the planned three. It was more than usual, but surprisingly manageable. Mari still felt a pleasant fatigue, yet she was sure she could get hard again if she wanted. Her cock was already twitching, half-ready. But looking at the state Seo-yoon was in, she decided against it.
“Hee, heehee…♡♡♡” “I guess that’s enough for today…” The moment the tension left her body, exhaustion crashed over Mari like a wave. She flopped face-down on the bed. “Ah, I should wash up… and clean Seo-yoon too…” Strength drained from her limbs and her eyelids grew heavy. Having poured everything out, she had no resistance left and surrendered to sleep. “Seo-yoon…” She murmured her friend’s name—the one she had just ruthlessly fucked—right before her eyes closed completely.
