Sunday Roy woke to find his stepsister's tits on his face. Again. Annoyed he shoved Kelsey off him. She laughed at his bright red flush.

"I thought you could use something to go with that morning wood."

"Get the fuck out of my room!"

"I'll get out of my bed if you join me in mine."

She shoved her off the bed.

"Fuck you!"

"Promise?"

Roy let out a scream of frustration and marched out of his own bedroom. He ran himself a hot shower and stepped inside. He smacked his palms against the shower walls. He cursed his parents for getting him into this mess. These last five months of living hell were all their fault. His father could have married any woman. Why did he have to choose the mother of his stalker?

Living together through their senior year had been a nightmare. Every conversation with her was loaded with innuendo. She stayed far too close and had a bad habit of touching him whenever and wherever she could. Only having their parents under the same roof kept her from going much farther. The promise of college out of state was the only thing that made it at all tolerable.

That's when everything fully went to hell. Their parents were arrested for embezzlement. The money dried up. He had to get a scholarship to attend classes at the local community college. The same one Kelsey attended.

The only thing they were allowed to keep was the house. It turned out their parents had signed ownership of the house over to them when they turned eighteen. It was being contested in court but for now they were still living together. Now, however, they were alone.

As the months dragged on her boldness grew. First it was dropping all coyness and just stating outright how much she wanted to fuck him. Tell him in detail how she wanted it. She wore less and less clothing around the house. Letting herself into his room had started last month.

Roy took a deep breath. He needed to calm himself down. He needed to think about something else. His mind drifted back to the one thing that made him happiest in this life: Power Girl. He pictured the busty blond superheroine in the shower with him. The two of them making out. As he let himself fall into the fantasy his dream girl shifted in his mind's eye. She was now a very real girl. One he lusted for only a little than Power Girl. She was Mia Brooks.

They had met in the library during study hall. She had been drawing a picture of Power Girl in her notebook instead of working. They bonded over their love of the character. It took some time, some trust, and some coaxing for them both to admit they had the hots for the heroine. Not only did she share his obsession was fucking sexy herself. He pictured her in a Power Girl cosplay as they made out. Her black skin complemented the white body suit. Her long curly black hair flowed down her back. Her DD breasts were smaller than Power Girl's but only because Mia was human. He cupped and played with them through the material.

As his fantasy played out, she shifted again. This time it went in a direction he was not prepared for. She was white again but now half his height. Her hair was shoulder length and dyed pink. She was thicker with a more pronounced ass. Her breasts were larger but still smaller than Power Girl's. Unlike the others she was totally naked. Unlike the others he could actually

feel

her flesh.

"Kelsey!"

He shut off the shower and stormed out of the bathroom.

"You know you want me!"

"No, I don't! you know what? I'm going to prove it to you. Right now!"

Back into his room he marched with her hot on his heels. He grabbed his phone and placed the call he'd been dreading and dreaming about for so long.

"Hey, Mia. Good, I'm good. I was wondering... I was wondering if you'd like to go out Friday night. Great! I'll pick you up at eight. Can't wait, either. See you then. Bye."

He hung up and looked at his stepsister triumphantly.

"See? That's the woman I want to be with. Not you."

She turned and marched out in a little huff. He was not aware of it in the moment, but he watched her shapely little ass jiggle with every step to her bedroom.

Monday Roy came home from his English class around ten. He dropped his bags by the door, exhausted. It was a hard class but at least it was a brake from Kelsey. He flipped on the lights.

"Holy shit!" he shouted, staggering backwards.

A strange woman was sitting on his couch, watching him. It took a moment for his brain to process two incredible facts about her. The first was that she was fucking Power Girl! It was as if his comic book crush had stepped right out of a panel and planted her fine ass on his couch, legs crossed. How was this possible? It couldn't be. Could it?

That's when he noticed the second thing about her. This woman was not real. Her skin was clearly artificial, as close to real without actually being real. The same went for her hair, her eyes, her lips, everything. She was also large. She was a doll. She was a fucking sex doll!

"What the fucking hell?"

He stepped forward to examine her. God, she was perfect. He got his face just inches from her face.

"Where the fuck did you come from?"

"Your dirty dreams," the doll said before grabbing his head and pulling him in for a long, passionate kiss.

Roy screamed and flailed until he was finally able to pull himself free.

"Wha the actual fuck?!"

"I see you meet my new dolly," Kelsey said.

She sauntered into the room naked as ever.

"Hey, Babe," she said to the doll.

"Hey, Babe," the doll said back.

She climbed onto the doll's lap and the two began to make out. Roy tried to look away but found he couldn't. His face burned with shame as he felt himself getting hard at the sight of them. It was because he was seeing Power Girl in the synthetic skin, he told himself.

"So, this is your boy, huh?" Power Girl asked.

"Yep. That's my boy toy."

"The fuck I am!" Roy spat.

Kelsey slid off her lap as Power Girl stood up. Roy stepped back a little as he saw the doll was a full head taller than he was.

"You will not talk to our owner like that."

"She doesn't own me."

"I saw she does."

"Well... that's... that's not up to you."

"Oh, but it is."

She pulled down her costume, revealing her naked body.

"What... what are your doing?"

She grabbed her breasts and began to pull.

"Kelsey!"

"You asked for this."

Power Girl's breasts and abdomen lowered on a hinge at her pelvis like the old head changing action figures used to do. She grabbed Roy by the shoulders with a strength he never imagined and pulled him toward her. Seeing the empty cavity approaching he began to flail around once more. It did not good. She easily turned him to face outward and shoved him inside before pushing her chest back up, sealing him in.

The world was totally dark. There was no where to move. He couldn't hear anything.

"Let me out of here!"

"No."

He jumped as little as he could. Power Girl's voice was right in his ears, at a strangely comfortable level.

"You're going to stay in here until your owner lets you out."

"She's not my owner!"

"We shall see."

The noise of the outside world came flooding back in. A light formed before his eyes. He could see again! He could see Kelsey. He was looking down at her. Something was wrong.

"Kelsey! Let me out of here!"

"She can't hear you. My body is soundproof. You only hear what I hear. You only see what I see."

That was it! He was looking down at her from another height. He was looking at her from Power Girl's eyes! Fuck, this was messed up.

"Bedtime," Kelsey beamed.

"After you, Babe," Power Girl said.

Roy watched as they walked right into

his

room and climbed onto

his

bed. He had nowhere else to look as he vision was filled with the first person POV of being fucked by his crazy stepsister. He tried his best to tell himself the erection he had was because he was inside Power Girl not that he was seeing Kelsey's giant tits bob up and down in his face.

The rest of the week was a blur. He knew they had stripped him on Tuesday before putting him back in. A warm, velvety fabric rose up to cover his ass and dick. He was confused at first until they started fucking again. The fabric moved, tightened, shifted, copied Kelsey's every movement as if the two of them were having sex, not her and her Power Girl doll. God, that girl was instable. They were fucking every hour it felt.

Even she had to go to class, however. Roy sighed in desperate relief. Maybe he could finally relax. He was mistaken. Power Girl pulled him out and pinned him to the bed. She grabbed his belt from the floor and bound his arms to the headboard.

"What...?" he asked weakly.

"Kelsey tells me you've been lusting after me for years."

"I..."

"That deserves a special treat."

That's when Roy's adolescent fantasies came true. Power Girl was fucking him.

"Mind if I join in?"

Kelsey stood in the doorway looking as sexy as ever. Had he thought that? Oh god, he

did

want her.

Friday night finally arrived. So did Mia. Roy's last-minute text had been strange. He wanted her to come to his house instead of him picking her up as planned. He also wanted her to dress as Power Girl. She had no idea he could be so kinky. She loved it. She knocked on the door. Roy did not answer it. Power Girl did. Mia was instantly wet.

"Who... how...?"

"My sex slave Roy tells me you've been lusting after me for years."

She nodded dumbly.

"That deserves a special treat."

Roy lay there smiling as the sun rose Saturday morning. He had just had the night of his life. He had just had a foursome with the three sexiest women in his life. His stupid fantasy was finally true. Mia had begged Power Girl to be her mistress too. So now the two of them would spend their days tied naked to his bed or shoved inside Power Girl together. They would be allowed to have sex only if Kelsey got to fuck him twice as long later. That was fine by him. Not that it mattered. They owned him now. He belonged to his sexy stepsister and her new dolly.
