Stepbrother's Big Cock

Aliya’s bedroom door was closed but not locked. The only light came from the small lamp on her nightstand. She lay on her back in the middle of the bed, legs spread wide, one of her mother’s old silk scarves stuffed between her teeth so the sounds would stay quiet. In her right hand she held a thick purple vibrator, the kind that buzzed deep and strong. She had already been at it for almost twenty minutes.

The head of the toy pressed hard against her swollen clit. Her hips rolled in small desperate circles. Every few seconds she pushed the thick shaft inside herself, then dragged it back out slick and shining before pressing it to her clit again. Her free hand squeezed one breast, pinching the nipple roughly the way she imagined Damon would.

“Mmmmph… Damon…” The name came out muffled around the scarf, low and broken. “Ahhhh… fuck me… please…”

She closed her eyes and pictured him. Their stepbrother. Tall, broad shoulders and muscle from the gym. The way his sweatpants hung on his hips when he walked through the hallway in the morning. The heavy outline she had caught more than once. She had been thinking about that outline for months since he moved in with them.

“Ahhhh… Damon… stretch me open… use me…”

The vibrator hummed louder as she turned the setting up. Her thighs started to shake. Wet sounds filled the quiet room every time the toy slid back inside her. She was soaked. The sheets under her ass were already dark with it.

She was so close that her toes had curled tight when the bedroom door opened.

Amelia stepped inside and froze.

For a second neither of them moved. Aliya’s eyes flew open. The vibrator was still buried inside her, still buzzing. The scarf hung from one corner of her mouth. Her chest rose and fell hard.

Amelia closed the door behind her without a sound and leaned against it. She did not look away. She did not pretend to be shocked. She just stared at her twin sister’s spread legs and the toy working between them.

Aliya pulled the scarf free. Her voice came out rough.

“How long were you standing there?”

“Long enough to hear you moaning his name.” Amelia’s voice was quiet but steady. “Damon. Our stepbrother.”

Aliya’s cheeks burned but she did not turn the vibrator off. She left it inside herself, the low buzz still traveling through her.

Amelia walked closer until she stood at the foot of the bed. Her eyes stayed locked on the place where the purple toy disappeared into her sister.

“I do the same thing,” Amelia said. “Almost every night. I put my hand over my mouth and I fuck myself thinking about him. I have always dreamed of Damon fucking me. Properly, holding me down and using that big cock I know he is hiding.”

Aliya’s breath stuttered. The vibrator kept pulsing.

“You too?”

“Yes.” Amelia’s voice dropped lower, dirtier. “I know he is thick, big and veined. You can see it when he gets a bit hard in those gray sweatpants in the mornings. I want him to split me open with it. I want him to talk filthy to me while he does it. I want him to fill me until it leaks down my thighs.”

Aliya slowly pulled the toy out of herself. It came free with a wet sound. She set it on the bed beside her hip, still glistening. Her pussy stayed open and shiny in the lamplight.

“I think about him holding my legs back and telling me I am his dirty little stepsister slut,” Aliya whispered. “I think about him making me take every inch even when it hurts at first. I touch myself until I can barely breathe and I still never get the real thing.”

Amelia climbed onto the bed and sat beside her sister’s hip. She reached out and ran two fingers through the wet mess between Aliya’s legs, slow and deliberate. Aliya moaned at the touch.

“Ahhhh…”

“We are both aching for the same cock,” Amelia said. “And he is right down the hall. Dad is out of town until Monday. Mom took her sleeping pills an hour ago. She will not wake up even if the house burns.”

Aliya’s heart slammed against her ribs.

“You want to go in there tonight?”

“Yes.” Amelia’s fingers kept moving, sliding up to circle her sister’s clit. “We will go to his room together. He will not say no hopefully. Not when he sees both of us naked and ready. And we tell him how long we have been soaking our sheets thinking about him and his big cock stretching our tight pussy.”

Aliya’s hips lifted into her twin’s hand. “Ahhhh… keep touching me while you talk…”

Amelia leaned closer, voice raw. “We make him lie back. We take turns sitting on his face so he can taste how wet he already makes us. We ride that thick cock one after the other until he is shaking. We keep a vibrator on his balls the whole time so he stays desperate and not cum. When we finally let him come we both stay on him. One of us takes every drop inside while the other sits on his mouth so he has to lick while he fills us. Then we make him clean both creampies with his tongue before we leave.”

Aliya moaned louder at the picture.

“Ahhhh… fuck… yes…”

Amelia pushed two fingers inside her sister and curled them. “We will do it tonight. No more just dreaming. No more quiet moaning into pillows. We will go in there and we will take what we have been aching for.”

Aliya’s orgasm was already building again under her twin’s hand. “He might try to stop us.”

“Then we do not let him,” Amelia said. “We are both wet and ready and we know exactly how bad we want that big stepbrother cock. He will see it on our faces. He will smell it on us. He will not be able to say no.”
