After a dangerous encounter with a trans-dimensional being claiming to be his mother, the protagonist returns home. His stepsister, Natalia, is overwhelmed with fear and relief, leading to a passionate night together. During their intimacy, they discover that the protagonist's recent integration has caused physical changes to his body, including an increase in size.

My hips slammed against hers with enough force to rock the entire bed. The headboard banged against the wall in a rhythm that would definitely be audible to anyone else in the house.

I didn’t care.

Let them hear.

Let them know exactly what was happening in this room.

Natalia’s moans turned to screams. Her body writhed beneath me. Her purple hair was a tangled mess across the pillows. Sweat gleamed on her skin.

"Yes yes yes yes right there don’t stop please don’t stop."

Her pussy tightened impossibly around me.

Her back arched.

Her eyes rolled back.

She came.

Hard.

The force of her orgasm milked my cock in waves that threatened to pull me over the edge with her. I gritted my teeth. Forced myself to keep moving. To fuck her through the climax and push her toward another.

"Satori!"

"I’ve got you."

"More. I need more."

I pulled out.

She whimpered at the loss.

"Turn over."

She obeyed without hesitation. Rolled onto her stomach. Pushed her ass up in the air. Looked back at me over her shoulder with those violet eyes that had haunted my dreams since the first day I saw her.

"Like this?"

"Perfect."

I grabbed her hips and slammed back inside.

This angle was deeper. The head of my cock pressed against something inside her that made her entire body shake. Her face dropped into the pillows to muffle her screams.

"Don’t hide from me."

I grabbed her hair. Pulled her head back. Made her look at me.

"I want to hear you."

"The whole house is going to hear me."

"Good."

I fucked her harder.

The wet sounds of our bodies connecting filled the room. The smell of sex hung heavy in the air. Natalia’s moans turned incoherent. Just sounds. Gasps. Pleas that weren’t even words anymore.

Her ass was incredible.

Full and round and heavy. It jiggled with every thrust. My hips slapped against it hard enough to leave red marks on her pale skin.

"You’re mine."

"Yes."

"Say it."

"I’m yours. Only yours. Forever."

"That’s right."

I felt my own climax building. That familiar pressure at the base of my spine. The tightening of my balls.

Normally I would pull out.

Tonight was different.

"Natalia."

"I know."

"I’m going to come inside you."

"Do it."

"Are you sure? The risk is."

"I don’t care about the risk. I want you. All of you. I want to feel you fill me up. I want to carry your seed inside me for as long as possible."

"You could get pregnant."

"I know."

She looked back at me again.

Her eyes were clear. Lucid. This wasn’t the heat of passion making her reckless.

She’d thought about this.

"I almost lost you three times in the past week. Once to Seraphina. Once to the integration. Once tonight on that pier. Each time I wasn’t sure you’d come back to me."

"Natalia."

"I don’t want to wait anymore. I don’t want to be careful. I don’t want to worry about what might happen or what could go wrong. I want to live. Really live. With you. Whatever that means."

"We’re eighteen."

"So?"

"Your parents would kill me."

"Luka would be furious for about five minutes and then start buying baby clothes. My mother would cry tears of joy. Your mother already treats me like a daughter."

"We have enemies. Powerful enemies. The VHC. The entity. This mysterious Remnant faction."

"All the more reason to grab happiness while we can. Before one of those enemies takes it away."

I stopped moving.

She was serious.

Completely and totally serious.

This wasn’t pillow talk. This wasn’t fantasy. She was telling me that she was ready to become a mother. That she wanted to carry my child. That she was willing to risk everything for the chance to create something permanent between us.

"You’re insane."

"I’m in love. Same thing."

"We should talk about this."

"We can talk later. Right now I need you to finish what you started."

"Natalia."

"Satori. Please. Give me this. Give me everything. I don’t want to think about cosmic entities or interdimensional conspiracies or the fact that your mother from another timeline just showed up to warn us about impending doom. I just want you. Inside me. Making me yours in the most permanent way possible."

I looked at her.

This woman who had started as my enemy. Who had hated me with every fiber of her being. Who had slowly fallen into my trap and then realized she didn’t want to escape.

She was offering me something precious.

Something irreversible.

Something that would tie us together in a way that even death couldn’t sever.

"If I do this."

"You’ll be a father."

"Yes."

"And you’ll have to stay alive to raise the child."

"I was already planning on staying alive."

"Now you have extra incentive."

She wiggled her ass against me.

My cock throbbed inside her warmth.

"Last chance to change your mind."

"Satori Nakano. If you pull out right now I will telekinetically remove your testicles and feed them to Maki."

"She would probably enjoy that."

"Stop stalling."

I grabbed her hips.

Pulled almost all the way out.

Slammed back inside so hard that she screamed into the pillows.

"Is this what you want?"

"Yes!"

"You want me to fill you up?"

"Yes!"

"You want to carry my child?"

"God yes please yes give it to me."

I stopped holding back.

My hips moved with a speed and power that surprised even me. The integration had changed more than just my perception. My body was faster. Stronger. More responsive to my desires.

Natalia came again.

And again.

Her pussy clamped down on me so hard that it was almost painful. Her screams filled the room. Her body shook with wave after wave of pleasure.

I felt my own climax approaching.

Unstoppable now.

"I’m going to come."

"Inside me. Please. Don’t pull out. Fill me up completely."

"Natalia."

"I love you. I love you so much. Please. Give me everything."

I buried myself as deep as possible.

My cock pulsed.

Thick ropes of cum erupted inside her. Filling her. Flooding her womb with heat and seed and the promise of something neither of us could take back.
