"Duality of Obsession"

1. Once upon a time, there lived a little boy named Ethan William Carter.
2. Ethan had been born on February 17th, 2020.
3. As of today, he was four years old.
4. He had just celebrated his most recent birthday with a small party at home.
5. It was a snowy, quiet day outside in the peaceful suburbs where Ethan’s family lived.
6. Ethan was white, with pale, soft skin that flushed pink in the cold.
7. He was a petite child, standing at 3’3” tall.
8. He weighed only 31 pounds, but his round cheeks made him look a bit chubby.
9. Ethan’s hair was golden blond, straight, and always slightly tousled, falling around his eyebrows in a boyish mop.
10. His eyes were wide, crystal-blue, always reflecting curiosity and innocence.
11. Ethan's family thought he was a clever, responsible boy for his young age.
12. That day, his parents had to run errands and trusted him to stay home alone for the very first time.
13. Ethan felt proud but nervous about their confidence in him; he wanted badly to prove himself.
14. Ethan wasn’t totally alone, though, because he had an older brother who lived at home.
15. His brother’s name was Thomas Carter, but everyone called him Tommy.
16. Tommy had been born on July 9th, 1998.
17. At twenty-five years old, Tommy was tall and broad-shouldered at 6’2”.
18. He weighed a lean 185 pounds, thanks to weekend pickup basketball games.
19. Tommy’s hair was a dusky brown, cut short on the sides and always brushed back.
20. He had green eyes that sparkled with mischief but were quick to narrow in suspicion.
21. Tommy had recently broken up with his girlfriend, and the split had left things tense.
22. The girlfriend’s name was Sabrina Monroe.
23. Sabrina was born on March 15, 1996, making her twenty-eight—three years older than Tommy.
24. She was 5’8”, with long legs and a dancer’s build, weighing around 125 pounds.
25. Her natural hair was a deep jet black, straight, and almost always kept in a high ponytail.
26. Her eyes were an unusually light shade of gray, rimmed with dark lashes.
27. Sabrina’s intense beauty was matched only by her intense personality.
28. Her style was bold and sometimes provocative.
29. Tommy had been clear with his family: “If Sabrina comes by, do not let her in—she’s weird, obsessive, and honestly, a little psychotic. Just don’t engage.”
30. That Saturday, Tommy joined his parents for a wedding hours away, promising to keep his phone handy in case Ethan needed anything.
31. Ethan was a little sad that Tommy, his hero, was leaving.
32. But being “big and responsible” was exciting.
33. His parents hugged him at the door and handed him a list of phone numbers “just in case.”
34. The house echoed with silence as Ethan watched them pull away.
35. For a while, Ethan sat cross-legged on the living room rug, building towers of colorful blocks.
36. Rain began to pitter-patter against the window, but Ethan was lost in play, making “whoosh” sounds as he zoomed a helicopter over the blocks.
37. The clock ticked quietly.
38. Suddenly, Ethan heard something strange, like a thud and a low rattling, coming from somewhere upstairs.
39. His small hands froze on the toy.
40. His eyes widened, and he glanced over his shoulder.
41. He was sure no one else was home—he had checked all the rooms with his mom before she left.
42. His heart pounding, Ethan tiptoed to the bottom of the stairs.
43. Another muffled crash sounded above him.
44. He gripped the banister with one hand and a plastic block in the other “just in case.”
45. He called out, “Hello?” softly, but there was no answer.
46. The sound seemed to have come from Tommy’s room.
47. Ethan knew Tommy’s room was off-limits, but something inside told him he had to check.
48. He slowly climbed the stairs, heart in his throat.
49. At the end of the hallway, Tommy’s door stood ajar.
50. He pushed it open with trembling fingers.
51. The moment Ethan stepped inside, someone lunged from behind the door.
52. He barely had time to squeak before he was tackled to the soft carpet.
53. Before he could wriggle away, strong arms lifted him and plopped him—roughly—into Tommy’s desk chair.
54. He squirmed, but thick rope was wound around his chest and legs, tying him securely to the seat.
55. He twisted around, but the knots held fast.
56. Panic flooded him as he looked up, expecting maybe his brother pulling a prank, but instead—
57. Sabrina Monroe stepped into his sight, closing the door with a click.
58. Today, Sabrina wore a neon pink crop top, ragged at the hem and tight to her body.
59. The short sleeves left her arms bare except for a jangly stack of bracelets.
60. Her shorts were impossibly tiny, ripped denim, showing almost all her long pale legs.
61. On her feet were tall white platform flip flops with jeweled straps, the soles ticking against the floor with every step.
62. Her toenails flashed bright yellow in the light, matching her fingernails—long, squared, and painted glossy sunbeam yellow.
63. As for jewelry, she wore:
64. 1. A collection of mismatched silver bangles on her left arm.
65. 2. A chunky gold hoop earring in her right ear.
66. 3. A slim gold chain around her neck with a blue heart pendant.
67. 4. A thin anklet hung loose on her right ankle, dangling small bells.
68. 5. On her left hand—a delicate silver promise ring, the one Tommy had once given her.
69. Sabrina watched Ethan with a wild, slightly glazed look in her ice-gray eyes.
70. “Well, well, aren’t you precious? I knew I’d find you here. Just the cutest little thing,” she crooned, tone wobbling between sing-song and shrill.
71. “Please… let me go,” Ethan begged, voice crackling with fear.
72. Sabrina waved a hand dismissively.
73. “Oh, don’t fret. You’ll be quite comfortable soon. But first, let’s try something fun.”
74. She slipped off her jeweled platform flip flops, then crouched to wedge them onto Ethan’s tiny bare feet.
75. Ethan’s toes barely reached the end, but somehow, the shoes seemed to grow tighter, warmer.
76. An odd tingling started in his toes.
77. The tingling quickly spread—cold, then hot, then unbearably itchy.
78. He watched as his feet began to change:
79. 1. His tiny toes lengthened, becoming more slender.
80. 2. His feet stretched and grew, the skin growing smoother.
81. 3. Arches formed, replacing the plump toddler fat.
82. 4. Toenails elongated, squaring out and gaining a glossy hardness.
83. 5. They brightened rapidly into a vivid, blinding yellow hue.
84. 6. The heels grew calloused, the feet now feminine and adult in shape.
85. 7. His ankles slimmed and lengthened.
86. 8. A soft scattering of almost invisible hair formed on his toes and knuckles.
87. 9. His entire foot widened proportionately, stretching the shoe perfectly.
88. 10. A silver anklet, just like Sabrina’s, materialized around his right ankle.
89. 11. The bones subtly shifted and relocated, removing any childish angle.
90. 12. Soft blue veins appeared under the translucent skin.
91. 13. The arch deepened alluringly.
92. 14. The scent of Sabrina’s perfume filled the air, an intoxicating floral.
93. 15. The veins and tendons were now visible, the feet unmistakably adult.
94. 16. The shape finally matched the dimensions and beauty of Sabrina’s own feet.
95. 17. The transformation sent hot tingles up his legs.
96. 18. Muscles flexed, grown from years of walking in heels.
97. 19. Each digit stretched and flexed independently, as if testing their newfound strength.
98. 20. Finally, the straps seemed to mold perfectly—Ethan’s feet were now identical to those of Sabrina, as if copied.
99. Sabrina bent closer, face split by an intense grin.
100. “Changing you, sweet thing. Now you’ll see—you won’t just *look* like me, soon you’ll *be* me. It’s better this way! Two of us can share the obsession. He’ll be your boyfriend, too. You’ll want him just as much as I do!” she cackled.
101. Ethan whimpered, “No, please! I don’t want—”
102. Sabrina ignored him, standing, her crop top riding higher.
103. “You’re not done yet,” she continued with a fevered giggle. “Time to transform into a complete copy of me. We’ll be twins—inside and out! Now relax, honey, it’s quicker that way.”
104. Ethan felt another icy rush pour from the shoes into his legs, traveling upward.
105. His calves thinned, lengthened, muscle and sinew reshaping.
106. His knees clicked and popped, growing and setting into adult height.
107. Thighs stretched, becoming slender and muscular, like those of a runner or dancer.
108. The change spread relentlessly, his shorts splitting apart as his hips widened, pelvis reshaping.
109. Waist narrowed, stomach pulling tight, smoothing into Sabrina’s flat abs.
110. Torso grew longer, ribs expanding, back arching.
111. Fingers elongated, skin smoothed, nails hardening and flashing yellow polish.
112. Arms thinned, shoulders becoming delicate and elegant.
113. A pressure in his chest—then, his frame blossomed out, and the same neon pink crop top formed, hugging his new curves.
114. Ethan’s neck lengthened, voice already wobbling to higher pitches.
115. His chin sharpened, lips plumping, nose reshaping to a slender tip.
116. Blue eyes faded, iris shifting to Sabrina’s impossible gray.
117. Lashes thickened, brows darkened and shaped.
118. Skin paled, freckles vanished, every blemish lost.
119. Bones clicked as his skull reformed, jawline sharpening.
120. A black, silken ponytail slid from his scalp, hairline tickling the nape of his slender neck.
121. His ears pierced themselves with a jolt, and just as quickly, gold hoop earrings winked into place.
122. Height increased rapidly; soon he was as tall as Sabrina, his former toddler body completely erased.
123. Sabrina #1 cackled and slipped her own bracelets onto Ethan’s—Sabrina #2’s—arm.
124. Another tickling sensation as a blue heart pendant materialized at his—her—throat.
125. Anklet bells jingled on her slim ankle, and a new promise ring glimmered on her small finger.
126. The platform flip flops now fit perfectly, as if made for her feet.
127. Sabrina #2 blinked as memories began to warp, childhood fading, mind filling with thoughts and obsessions not her own.
128. She—no, *I*—stood up shakily, feeling the crop top’s hem brush her smooth stomach.
129. Sabrina #1 grinned, clapping her hands.
130. “Perfect! It worked! Double the fun now.”
131. Sabrina #2’s thoughts shifted—where was the little boy? Wait, no, I’m—Sabrina.
132. She smiled uncertainly, then more confidently as strange new feelings bubbled up: possessiveness, longing, and an icy certainty that Tommy was *hers* and hers alone.
133. She turned to face Sabrina #1, and time pulsed oddly as new truths replaced the old.
134. Childhood memories blurred, replaced by bikini selfies and text arguments and Tommy’s lips.
135. Sabrina #2’s mind latched onto a desperate obsession—Tommy must be hers.
136. She caught her own reflection in Tommy’s wall mirror, matching Sabrina #1 in every detail: the crop top, the ponytail, the intense gaze.
137. Sabrina #1 watched, giddy and wild-eyed.
138. Sabrina #2’s face twisted into a jealous sneer as she looked at her twin.
139. With a shake of her dark ponytail, Sabrina #2 strode forward and demanded, “Who are you? He’s mine. I’m Sabrina. You can’t have him!”
140. Sabrina #1’s mouth opened, surprised at the aggression mirrored back at her.
141. They glared at each other, both possessive, both predatory.
142. “He’s mine, you psycho!” Sabrina #1 snapped back.
143. “No, *I* am Sabrina, and he belongs to me!” Sabrina #2 hissed, voice thick with fury.
144. Each stalked the other around the cramped room, their matching flip flops ticking sharply.
145. Sabrina #2’s mind spiraled: images of Tommy, kisses, laughter, jealousy, possessiveness, loops of arguments and makeups.
146. The fire between them threatened to spark into violence.
147. Sabrina #1 made a play for the doorknob, but Sabrina #2 dove and tackled her twin.
148. Cropped neon shirts tangled, bracelets flailing, as they wrestled on the carpet.
149. Their voices mingled—all shrill, all furious, all desperate for Tommy.
150. On the floor, Sabrina #2 screamed, “I know all his secrets! His favorite breakfast, the song he cries to, what he’s like in bed!”
151. “I *taught* him what he’s like in bed! You’re just a copy, an echo, a nothing!” Sabrina #1 spat with venom.
152. Sabrina #2 sank her fake, newly strong nails into Sabrina #1’s arm.
153. They shoved, rolled, tumbled, hair and jewelry flashing, matched in every way.
154. “Give it up, copycat,” Sabrina #1 groaned through gritted teeth.
155. “I’m real. Only I remember everything, every *feeling*!”
156. Sabrina #2 gasped—something in her mind turned, remembering childish toys and blocks just beyond her grasp.
157. It was confusing, but fury overwhelmed any uncertainty.
158. A lamp crashed as they knocked the table over, glass splintering the silence.
159. Sabrina #1 finally managed to pin Sabrina #2 to the ground.
160. “Listen! There’s no room for two of us—*he* won’t believe there’s two of me. I have to be the only one. Give in! Fade away. Let me have him!”
161. Sabrina #2 snarled, “Never. He'll love me. I’m the new, better you. And you’re old news!”
162. They broke apart, glaring daggers.
163. Sabrina #2 staggered upright, chest heaving, ponytail askew.
164. Her promising ring gleamed as she lifted her hand, gesturing to the mirror.
165. “Look! Which of us is real? Which will he choose?”
166. They both advanced on the mirror, faces inches apart with identical glares.
167. Downstairs, the clock chimed softly, unnoticed by the warring Sabrinas.
168. Sabrina #1 growled, “Let’s see whose obsession is stronger. Time for a test!”
169. She darted from the room, Sabrina #2 hot on her heels.
170. On the upper landing, they paused, listening, suddenly aware that neither Tommy nor Ethan were in the house.
171. “He’s not home! Where is he?” Sabrina #2 demanded.
172. “He left you—left *us*,” Sabrina #1 spat.
173. The words set off another spark of anger in both.
174. “He’ll come back. He always comes back,” Sabrina #2 said in a hiss, voice trembling.
175. “He can’t resist *me*.”
176. “No, he can’t resist *me*—the real one.”
177. They circled each other on the stairs, fury and possessive longing pulsing between them.
178. Somewhere in Sabrina #2’s mind, an echo whispered: *You were Ethan once. You’re not real...*
179. She shoved it aside, need for Tommy prevailing.
180. Sabrina #1 gripped the banister, knuckles white.
181. “We need to clear this up—Tommy will be home soon. He’ll see us both. He’ll have to choose.”
182. “He will choose me. I’ll make him. I *remember* everything, just like you,” Sabrina #2 insisted firmly.
183. “Liar,” Sabrina #1 said, voice shrill.
184. “We’ll see.”
185. Meanwhile, Sabrina #2’s memories were continuing to alter, Ethan’s boyhood vanishing further, replaced by Sabrina’s obsessive past and tangled romance.
186. Her voice and body were now hers entirely—her mind, nearly so.
187. She opened Tommy’s drawers and began rifling through shirts, seeking any clue, something to prove her authenticity.
188. Sabrina #1 watched jealously.
189. “You know nothing. Watch—you’ll mess it up! That’s his band shirt. He hates that one!” she taunted.
190. Sabrina #2 faltered, doubt etching her now-perfect face.
191. “I—I know he likes the blue one. He wore it on our anniversary…”
192. “Wrong! That was my birthday. Yours is just a memory borrowed, not lived.”
193. A dark silence filled the room.
194. Outside, thunder rumbled—the world unaware of the war inside Tommy’s home.
195. Sabrina #2 stalked to the window, peering out at the darkening street.
196. “He *will* pick me. I’ll make him love me more than you ever could,” she whispered, voice haunted.
197. Sabrina #1 drew near, resting clawed yellow nails on the window frame.
198. “You’re as broken as I am,” she murmured.
199. For a moment, the two stood side by side, identical and tormented.
200. Sabrina #2 felt a flicker, a dim shadow of playing with blocks, of a mother’s hug, gone in a whipped instant.
201. “I am Sabrina,” she insisted to herself, determined, forgetting the name Ethan entirely.
202. “Yes, you are. And so am I,” Sabrina #1 echoed, like a curse.
203. The hours ticked by, the house oddly still as both Sabrinas waited, love and hate warping within them.
204. The clock struck midnight; no one came home.
205. Sabrina #2 gazed into the hall mirror, smile fading in confusion.
206. “Why do I feel…wrong?” she muttered, voice trembling ever so slightly.
207. “New bodies always take time to grow into,” Sabrina #1 sneered, watching.
208. Sabrina #2 spun, hair flying.
209. “No more games. We settle this now. One Sabrina, one Tommy!”
210. With a shriek, she launched herself again at her twin, fury and longing mingling.
211. They clashed, again and again, fighting for all the love and obsession the real Sabrina had ever known.
212. Downstairs, the key finally jangled in the lock—the family was home.
213. But the house was silent, no sign of Ethan to greet them.
214. Walls trembled as the Sabrinas warred in Tommy’s bedroom, fighting for the right to own a love that had become fractured between them.
215. Tommy, tired and unsuspecting, called out, “Ethan? Sabrina?”
216. Both Sabrinas paused, bruised and wild-eyed, at the sound of his voice.
217. Their eyes glittered as one, and with a final act of desperation, they raced together; two sets of identical legs charging down the stairs, hair flying, voices twisting into a single cry: “Tommy!”
218. He recoiled in shock as two identical Sabrinas sprinted at him, each wrestling the other aside to reach him first.
219. “What the—You—” he stammered, eyes wide.
220. “I’m Sabrina! She’s the imposter!” Sabrina #2 insisted, tears in her gray eyes.
221. “No, I’m Sabrina! She’s the fake!” Sabrina #1 yelled, voice hoarse with exhaustion and longing.
222. Tommy looked from one to the other, mouth agape, mind reeling.
223. Their parents called from the kitchen, uneasy at the strange scene before them.
224. “Ethan?” his mother cried, worry sharpening her voice.
225. Both Sabrinas froze, one foot poised on the bottom step.
226. Somewhere in Sabrina #2, a last flicker of boyhood Ethan stirred—a tiny, strangled cry, “Mom?”
227. The word was lost in the storm of obsession, drowned in Sabrina’s possessive longing as the final piece of Ethan faded away.
228. Sabrina #1 saw the shadow cross her twin’s face and smiled coldly.
229. “You’re nothing, just a shadow. He’ll know. He’ll pick me.”
230. Sabrina #2’s jaw clenched, yellow nails digging into her palms.
231. “Never. I *am* Sabrina, and I deserve him.”
232. Tommy stepped backward, fear and confusion in his gaze.
233. Both Sabrinas closed in, voices merging, faces plastered with desperate, matching grins—
234. “Choose me, Tommy!”
235. The choice was an impossible one—one girl split into two, love and hate in equal measure.
236. In the flickering hallway light, their shadows tangled as they reached for him, relentless and broken.
237. Upstairs, the house still echoed with the happy, innocent laughter that had once belonged to Ethan, now lost forever.
238. Tommy’s hand trembled as he faced the impossible twins, the last normal moment slipping away.
239. And in that suburban house, obsession had truly doubled, leaving the Carter family—now and always—one son short, and two Sabrinas too many.
240. The end.
