The next morning at St. Mary's dormitory in London, the faint autumn sunlight filtered weakly through the heavy, thick curtains, casting pale golden streaks across the two bodies still tightly entwined on the narrow single bed. The dormitory room carried the characteristic crisp chill of October, when the leaves outside the window began turning yellow and light drizzle often fell on the quaint streets of Kensington. Ami lay on her side, her back pressed firmly against Rie's full, warm breasts. Her cousin's arms wrapped tightly around Ami's waist from behind, her fingers unconsciously squeezing the soft, pinkish-white skin. Rie's steady breath brushed against the nape of Ami's neck, carrying the scent of fresh milk mixed with the faint fragrance of English roses from last night's bath. Both of their intimate areas were still sore and slightly burning after the long night of being "tortured" by Free at the luxurious mansion.
Ami's pussy was slightly swollen and red, its pink folds twitching with waves of painful pleasure with every small movement. Dried love juices stuck stickily between her smooth thighs, forming a thin, glistening film under the weak sunlight. Each time Ami shifted even slightly, a burning sensation spread from deep inside her womb to the outer lips, forcing her to bite her lip to suppress a soft moan. Rie was no better—her inner thighs still bore faint pink marks from the leather whip, and her nipples were slightly bruised purple from the metal clamps that had been tugged and pulled for hours in the underground basement. Her anus remained slightly stretched and unusually sensitive; every contraction made her shiver from the lingering echoes of the powerful thrusts from the enormous dildo Free had used mercilessly.
Rie gently kissed the nape of Ami's neck, her warm lips gliding softly over the porcelain-smooth, youthful skin like silk, then slowly licking a long trail from the nape down to the shoulder, leaving a hot, glistening trail of saliva sparkling in the sunlight. She rubbed her full breasts against Ami's back, her hardened nipples rubbing through the thin nightgown, her voice whispering with a mix of guilt and tenderness, her breath trembling against Ami's skin:
"Little sister… I'm sorry… Last night Free hurt you so much, didn't he? I saw you being pounded so hard that tears streamed down your face, your pussy clenching and shaking all over, your love juices spraying everywhere across the basement floor… I couldn't protect you in time… I feel so guilty, Ami."
Ami slowly turned around, her delicate, beautiful face still retaining the innocent, pure look typical of a 16-year-old girl, with rosy cheeks and sparkling dark brown eyes. Yet deep within those eyes, the sharp, cold, calculating gaze of Nguyễn Hoàng Kim Long flickered with amusement and dark delight. She shook her head slightly, her voice trembling in a feigned show of weakness, tears welling up in her eyes under the dim light:
"I… I'm still a little sore. My pussy burns every time it twitches… but I'm okay, sis. More importantly, are you alright? Free was… really rough with you. He pounded me so hard with that huge dildo all the way to my womb, whipped my breasts until they were bruised purple… You were beaten a lot too. Your anus is still stretched like that—every time I touch it lightly, you shiver from the pain."
Rie's face flushed crimson all the way to her ears, her cheeks burning like fire. She bit her lower lip hard until it turned pale, hesitating for a long time, her fingers gripping the bedsheet so tightly that her knuckles went white. After a heavy silence, she suddenly whispered something that made Ami's heart skip a beat inside, while Long within her laughed savagely with dark pleasure, a wave of twisted ecstasy spreading through the slender body:
"Actually… I don't hate that feeling. It hurts… but it feels so good. When my hands were tied tightly above my head, when the hot whip lashed my ass and inner thighs, when Free pounded me so hard with that enormous dildo that it reached my womb, making me ache while my pussy got soaking wet… I felt completely conquered, with no way out. I'm so ashamed, but my pussy was drenched just from the slaps and the ropes… My love juices flowed down my thighs and anus just from the pain. I never thought I would be the kind of girl who likes pain like this… who enjoys being tormented and humiliated to the point of crying from pleasure."
Long inside Ami's body laughed darkly and savagely. A sick wave of pleasure spread like black electricity. "Finally, she admitted it. Rie isn't just innocent on the surface—she has a dangerously strong masochistic tendency hidden inside. Even more perfect than anything I ever dreamed of in my previous life. Now she is mine, completely and absolutely. No one can take her away."
She pretended to be utterly shocked, her eyes widening with teary innocence, her voice filled with worry mixed with the naive curiosity of a young girl, her hand gently stroking her cousin's cheek:
"Sis… you like pain? Aren't you scared? Aren't you afraid of getting really hurt? Aren't you scared your pussy will be ruined, your nipples pinched until they swell purple, your anus torn and burning for days afterward?"
Rie lowered her head deeper, her cheeks burning red like ripe persimmons. Her fingers gripped the bedsheet so tightly her knuckles turned white, and her thighs unconsciously rubbed against Ami's, causing more leftover love juices to leak out and soak the thin sheet. Her voice trembled with shame but also with raw desire:
"I don't understand it myself. Before, I never thought about these things. But ever since I 'raped' you while drunk, and then last night when Free tied me up and beat me… I discovered that I like being completely controlled. I like the sharp pain mixed with overwhelming pleasure that makes my whole body shake, tears flow, and my pussy clench nonstop. I want… to try more, but only with you. I don't want anyone else to touch me, not even a single finger. I want you to hurt me… in your own way—gently, but enough for me to clearly feel that I belong to you."
Ami smiled softly and hugged her cousin tightly, her youthful breasts pressing firmly against Rie's full D-cup breasts. Their nipples rubbed against each other through the thin silk, creating small sparks of friction that made both of them shiver lightly. She whispered hotly and tremblingly into her sister's ear, gently biting the earlobe before licking it slowly:
"If you like it… I can try hurting you a little. But only lightly, okay? I don't want you to really get hurt. I just want you to feel good… and to belong to me completely. I'll tie you up, spank you, make you cry from pleasure, then kiss you tenderly afterward, wipe your love juices clean, and caress every red mark on your skin."
Rie nodded eagerly, her eyes sparkling with a new, greedy layer of lust that bordered on madness. Her breathing grew rapid as she panted against Ami's neck:
"Yes… I trust you. I want you to hurt me… in your way. I want to be completely conquered by you, with no way back."
From that moment onward, the outward lives of the three girls—Ami, Rie, and Mako—returned to complete normalcy: strict and obedient, just like typical students at St. Mary's Catholic School. During the day, they wore neat uniforms: pristine white blouses that hugged their budding young breasts, with nipples sometimes secretly hardening under the thin fabric from memories of the previous night; dark green vests embroidered with a shining golden cross emblem; light gray pleated skirts that fell just past the knees; and white thigh-high socks that clung to their flawless, smooth skin. They bowed politely to teachers with clear, sweet voices, attended morning prayers in the ancient chapel where the organ music echoed beautifully through the sacred space, studied advanced mathematics, English literature with works by Shakespeare and Jane Austen, European history from the Middle Ages to the Industrial Revolution, and especially music—the subject in which Ami shone the brightest.
Ami continued to impress everyone with her increasingly profound and emotionally rich piano playing, carrying the tragic depth of Nguyễn Hoàng Kim Long's past life. Beethoven's sonatas flowed from her fingers with perfect technique and profound emotional layers, leaving teachers and classmates in awe. Rie played the violin beautifully, her slender fingers gliding gracefully across the strings, though sometimes they trembled slightly from the lingering soreness of the whip marks on her inner thighs, forcing her to bite her lip to hold back. Mako sang with a pure, sweet soprano voice like a ringing bell and was often chosen as the soloist in the school choir. The three of them frequently sat together at lunch in the spacious dining hall with its high ceilings and ancient religious paintings, laughing and chatting cheerfully about Beethoven, Mozart, or traditional ballroom dance practice. No one at school suspected anything—they were simply three close Asian friends who were always together like shadows, strictly following the Catholic rules of the prestigious school.
After the incident at the mansion, Mako had apologized sincerely many times, her eyes filled with tears and her voice trembling with regret. She controlled her "Free" personality much better by taking her medication regularly as prescribed and keeping a daily journal to monitor her emotions. Free only appeared occasionally in dreams or deep private moments and had never taken control of Mako's body at school again. The three girls maintained their friendship and had even grown closer and more trusting because they shared a big, dangerous secret—a hidden bond that drew them nearer than ever.
But when night fell and private moments began, the relationship between Ami and Rie entered a completely new phase—gentle, discreet masochism that grew increasingly intense and lewd, like a smoldering fire burning quietly beneath cold ashes.
After turning off the dormitory lights and carefully locking the door twice, Rie snuggled tightly against Ami, pressing her cheek firmly against her cousin's youthful breasts. Her own chest heaved heavily, her voice trembling with unhidden shame and desire:
"Little sister… I want to try tonight. I want you to tie me up a little… and spank me lightly. Just enough to give me that painful pleasure, without leaving obvious marks. I… I crave the feeling of being conquered by you so much. My pussy has been wet since afternoon—just thinking about it makes my love juices flow and soak my panties."
Ami nodded. Long's heart pounded with dark excitement. She took a thin silk ribbon from a scarf and tied Rie's hands securely to the headboard—not too tight, just enough to prevent struggling while ensuring safety and normal blood circulation. Rie lay on her back, her full, pinkish-white body stretched out under the soft, warm glow of the bedside lamp. Her D-cup breasts rose and fell dramatically, her brownish-pink nipples already rock-hard, trembling with each rapid breath. Her slim waist and full hips stood out clearly. Her pink, youthful pussy was already soaking wet, the puffy folds spread open, thick, clear love juices leaking out in long, sticky strands that dripped onto the bedsheet, soaking her anus and forming a large, glistening wet patch that slowly spread.
Ami knelt between her spread thighs, gently stroking the silky-smooth inner thighs. Her fingers brushed once over the pussy before suddenly delivering a precise, light but sharp slap—"Smack!"—right on the outer lips of Rie's pussy, making the flesh jiggle. The crisp sound of skin-on-skin echoed in the quiet dormitory room, where only the patter of London rain could be heard outside the window.
"Ahhhh…!" Rie's entire body jerked violently. A soft, pleasure-filled moan escaped her throat, her eyes widening slightly. It wasn't pure pain—the moan carried clear, lewd desire, like an invitation. Rie's pussy immediately clenched hard, and even more hot love juices leaked out, flowing down in a small stream to her anus and soaking the sheet.
Ami continued, her voice sweet yet now carrying a new tone of authority and possessiveness. Her hand slowly caressed Rie's nipple:
"Are you being a good girl? If you moan too loudly, I'll spank you harder. You have to hold it in, or I'll punish you more severely. I'll make your pussy ache but feel so good that you'll beg me not to stop."
She delivered a few more light but firm slaps to Rie's inner thighs and round, white-pink ass cheeks. Each crisp "smack smack" made the flesh ripple, leaving faint pink marks that burned hotly and spread like deep red flowers blooming on pale skin. Rie bit her lower lip until it bled, her body shaking violently. Her hips unconsciously pushed forward, begging, as love juices flowed profusely:
"Little sister… harder… I can take it… My pussy is burning so much… it's completely soaked… my juices are flowing so much… spank me more… I want it to hurt a little more…"
Ami leaned down, her long, silky black hair cascading over Rie's belly like a silk curtain. She slowly and lewdly licked from the anus up to the pussy, sucking hard on the swollen, cherry-red clitoris, swirling her tongue around it before sucking strongly enough to make Rie's whole body jerk. At the same time, her middle and index fingers thrust deep into the tight, hot pussy, rapidly and forcefully rubbing the sensitive G-spot. The wet, obscene "schlick schlick schlick" sounds filled the quiet room, mixing with Rie's suppressed panting and moaning. A third finger slipped into her anus, gently twisting, making Rie feel completely filled in both holes.
Rie jerked violently, the silk ribbon cutting into her wrists until they turned white. She tried to suppress her moans but couldn't, tears streaming down her face from overwhelming pleasure:
"Ah… aaaahhh… little sister… I'm about to cum… spank me more… I love when you punish me… harder, please… my pussy wants you to torment it… spank my nipples too… pinch them harder…"
Ami slapped her full breasts harder, the "smack smack" sounds ringing continuously, then used her thumb and index finger to pinch and tug the nipples hard, twisting them until Rie felt sharp pain mixed with extreme ecstasy. The intense mix of pain and pleasure sent Rie over the edge immediately. Her body arched like a drawn bow, her pussy clenching violently around Ami's fingers. A thick, hot stream of love juices gushed out like a fountain, soaking Ami's mouth, chin, chest, and the bedsheet into a large, glistening, sticky puddle. Rie trembled for nearly two minutes, eyes half-rolled back, mouth open in broken, hoarse moans of mingled pain and pleasure: "Little sister… I'm cumming… so much… aaaahhh!!! My pussy… feels so good… it hurts but feels so good… I can't take it anymore…"
After Rie reached her peak, Ami gently untied the ribbon, pulled her into her arms, and tenderly wiped away the love juices with a warm towel she had prepared. She kissed every red mark on her skin and licked the remaining juices from her thighs. Rie panted heavily, her voice filled with happiness and extreme shame, tears rolling down her cheeks:
"Little sister… I'm addicted now. A little pain feels so much better… Thank you for indulging me… I'm yours now… completely."
Subsequent Evenings – Gradually Increasing Intensity and Deepening Addiction
From then on, they experimented more, going deeper and becoming lewder, but always maintaining absolute safety and discretion. They placed great emphasis on aftercare to ensure no physical or emotional harm. Ami studied carefully from books and knowledge from her previous life, ensuring every session had clear consent, a safe word ("red" to stop immediately), and checked blood circulation after tying.
One Wednesday evening, after finishing prep time (usually from 7 PM to 9 PM), Ami secretly bought a soft but sturdy leather whip from a small shop in Kensington during weekend free time. When Rie knelt on the bed on all fours, her round ass raised high like a begging cat in heat, Ami lightly whipped the white-pink cheeks. The sharp "swish… smack!" sound rang out, leaving a bright red, burning stripe that spread quickly. Rie moaned lewdly, pushing her hips back begging for more, love juices dripping onto the sheet like rain: "Harder, little sister… whip me harder… I want it to hurt more… my pussy is clenching from wanting it…"
Ami made her bend down and lick her own pussy while continuing to whip her ass and inner thighs steadily. Rie's tongue licked frantically and greedily from the anus up to Ami's pussy, sucking hard on the clitoris until Ami shuddered and sprayed love juices all over her face, soaking Rie's hair and cheeks. Then Ami yanked Rie's hair hard, pressing her face tightly against her pussy and forcing her to drink every drop of hot love juice: "Lick it all clean, sis… You're my pussy-licking slave. Drink all my juices, don't leave a single drop."
Rie especially loved being gagged with Ami's soaking wet panties. Every time the damp fabric, soaked with her cousin's lewd scent, was stuffed into her mouth, she trembled harder. Her pussy clenched tightly around Ami's three thrusting fingers as they furiously rubbed her G-spot, causing love juices to splash everywhere on the bed. Ami also pulled her hair harder while she licked, making Rie moan through the gag, love juices streaming down her white-pink thighs as her anus twitched in rhythm with the lewd frenzy.
Another night, when the London rain fell heavier than usual, Ami tried adding a blindfold and light nipple clamps. Rie was completely blindfolded with a black silk scarf, lying on her back with her hands tightly bound. Small metal clamps gently tugged at her nipples. Ami whipped the inner thighs, flat stomach, and spread pussy. Each strike made Rie moan lewdly through the gag, her body jerking as love juices spurted out in small waves. Ami thrust fingers deep into both her pussy and anus at the same time, twisting hard, licking the clitoris while tugging the clamps, causing Rie to orgasm three times in a row. Her love juices soaked the entire bed, her body convulsing like an epileptic fit, moaning through the gag: "Mmm… little sister… I'm cumming again… it hurts so good…"
After every session, Ami always provided extremely gentle aftercare: applying cooling lotion to the red marks to reduce swelling, kissing every whip mark as if apologizing and comforting her, gently stroking from breasts down to the pussy, licking away the remaining love juices, then holding her in warm arms while whispering praises and affection: "You were such a good girl. My sister is the most wonderful." The contrast between "extreme painful pleasure" and "tender love" made Rie increasingly dependent, loving, and addicted to her cousin until she could no longer leave her. She began proactively begging every night after lights out: "Little sister… tonight I want you to tie me tighter… and whip me a little harder… I want you to humiliate me, call me your lewd slave… I want to cry from pleasure."
During the day, all three continued their studies according to the strict dormitory schedule. They woke at 6:45 AM, had breakfast from 7:15–7:45, and arrived at school by 8:10. Classes alternated with short prayer times, lunch, and afternoon prep. In the large music practice room when no one else was around, Rie would sometimes glance at Ami with obvious, suppressed lust. Under the piano, she would secretly rub her smooth thighs firmly against her cousin's, revealing that her white panties were already soaked with love juices, and secretly stroke Ami's thigh under the skirt. Ami would only smile secretly and whisper in a sweet but possessively meaningful voice:
"Focus on studying, sis. Tonight I'll 'teach' you a different lesson… a much harder one, much more painful. I'll make you cry from pleasure. I'll make your pussy swollen and red and your love juices flow nonstop."
Mako noticed the clear change between the two sisters but didn't ask too deeply. She only smiled shyly, her cheeks slightly flushed when sitting together at dinner:
"The three of us… let's keep the secret, okay? Free promised she won't appear anymore, but if you two want… Free can join once, with Mako's full consent. Free… also wants to play with you two, wants to tie and whip Rie a little more—gently, of course."
Ami glanced at Rie and saw her nod slightly with eyes full of excited, lewd curiosity. Her cousin's thighs were definitely wet again under the uniform skirt right then. Long inside her laughed savagely: "Perfect. Now it's not just Rie, but Free too. Life in London is getting more and more interesting… and delicious than ever."
That weekend, on a typical London afternoon of light drizzle—rain falling gently on rose gardens and golden autumn leaves swirling in the chilly breeze—the three girls sat in the ancient library under the soft, warm glow of the lamps. Ami held a book of Beethoven's music, Rie sat close beside her, secretly squeezing her cousin's thigh hard under the table until Ami had to bite her lip to suppress a small moan of pleasure. Mako sat opposite, her voice soft but trembling with anticipation:
"Tomorrow night… if you two want to try again at the mansion, this time Mako will be fully in control. I won't let Free take over. We can… play more gently, or… a little harder, depending on what you want. Free can tie up sister Rie, whip her, and then let Ami join fully."
Rie blushed, glancing at Ami with lust-filled eyes, her thighs rubbing together from desire. Ami smiled, her voice clear but carrying Long's deep, possessive intent:
"Sure. But this time I want to try a slightly different role… I want to see how much sister Rie can endure. I want her tied up, beaten, made to produce so much love juice that she cries and begs, and then I'll take care of her very gently afterward."
Outside the library window, London drizzle fell gently on the rose garden, golden autumn leaves swirling in the chilly breeze. School life continued peacefully and strictly according to Catholic rules: morning and evening prayers, diligent study, and extracurricular activities like choir and ballroom dancing. But beneath the obedient exterior of the three St. Mary's girls, the flames of desire—with shades of masochism, manipulation, possession, and new discoveries—were smoldering, waiting for the moment to erupt even more fiercely and dangerously than ever.
Ami—or more precisely, the soul of Nguyễn Hoàng Kim Long—looked at Rie and Mako, thinking with a cold, calculating smile:
"Sister Rie has completely fallen into the trap. And now, we will play by my rules. No rush. Slowly… every centimeter of burning skin, every broken moan of pleasure, every thick, hot drop of love juice, every bright red whip mark spreading across her skin. She will become so addicted that she can't live without me."
That night, in the dormitory room before sleep, Rie whispered into Ami's ear with a trembling voice full of anticipation and craving, her hand secretly stroking her cousin's breast through the nightgown:
"Little sister… tomorrow I want you to tie me tighter and whip me a little harder. I want to clearly feel that… I am completely yours, your sex slave. I want you to hurt me, torment me until my pussy is swollen red and my love juices gush nonstop, then hold me while I sleep."
Ami kissed her lips lightly, then bit her lower lip harder, prolonging a lewd, deep kiss with tongues intertwining passionately. Her voice was sweet yet full of possession and lewdness:
"Alright, sis. I'll make you feel good… and hurt you exactly the way you want. You'll cry from pleasure, moan from pain, and beg me not to stop. Tomorrow I'll turn you into my real masochistic little slut, but you'll still be my beloved sister."
Outside, the London rain continued falling steadily, concealing the lewd, masochistic, addictive, and increasingly deep, complex, and irreversible dark desires growing within the hearts of the three girls. Those nighttime "gentle study sessions" were not just sexual games—they were becoming tighter spiritual bonds, where pain and pleasure merged, where Rie gradually became her cousin's willing slave, and Long—inside Ami's body—savored every moment of perfect conquest.
