Ally Tells Her Sister

Deciding it would be the better choice to actually have an ally in the house, Ally rose from her bed with purpose. She pushed open her bedroom door and began the long journey through the cold hallways of Scream House, until she reached the large, double-doors of the master bedroom. Her knuckle rapped against the door with confidence; she was there for a reason. She was there with purpose. She needed to see her sister.

The doors creaked open, but only a crack. Ally saw Kate's single eye stare back out at her, clearly frustrated to see her.

"What do you want?" Kate asked.

"I have to tell you something," Ally said.

"Go ahead then," Kate said. "I'm not opening the door to someone like you."

"I'm your sister," Ally reminded her, trying not to be hurt by Kate's words.

"I can't think of you that way, anymore. Not after what you did." The doorway opened wider, but only so that Kate could more comfortably lean against the doorway. Ally saw that her sister's panties were being stretched out by a penis, at least semi-hard. Kate turned so that Ally couldn't stare. "Did you come here just to ogle me? Just to be proud of what you did to me?"

"It happened to me too," Ally said, gesturing to the dick pressing against her own, thin underwear. "I came here because I found a message from Grandpa."

"And?" Kate asked. Even though she tried to remain stoic, Ally saw her eyes soften, just the smallest bit.

"He talked about the strange things that happen in this house -- like magic and demons and ghosts and stuff," Ally said. "I wouldn't believe it but..."

"But two girls just don't grow penises without a little magic being involved," Kate finished. "But, so what? What are we supposed to do about it? Did he leave you any ways to reverse the spell or anything?"

"I... I didn't get that far in the reading," Ally confessed.

"So you're here because..."

"The book warned me about... side effects of the house," Ally said. "And I wanted to pass on that warning. Um. The book said... as Scream girls... we might find ourselves uncontrollably aroused... like all the time."

"Uh-huh," Kate said, her voice hostile again. "Now you're sounding actually crazy, Ally."

"I'm not!" Ally shouted, her own frustration mixing with her horniness, the cool air of the house like a constant kiss around the sensitive tip of her cock. "Don't you feel it? Even a little? Kate, I'm not crazy, the house is so, so, fucking horny."

"Okay, Allyson," Kate dismissed, turning her back and stepping away from the door. "Whatever you say. Go back to bed, I'll pretend this little conversation didn't happen."

"Wait!" Ally shouted, reaching for her sister. Her hand landed on Kate's shoulder, spinning her around, and in the heat of the moment Ally couldn't think of anything else to do: She pulled Kate close, pressing her lips against her big sister's.

For a moment, the world stopped turning. Ally smelled the familiar scent of Kate's breath as their lips pressed against each other, aggressively at first, as Kate tried to pull away, but then soft, gentle, as the sisters both eased into the warmth of each other's mouths. Ally pressed her hips forward, rubbing her panties against her sister's, feeling the warmth of their cocks, separated by less than an inch of fabric; her hands rose up, beneath Kate's shirt, until Ally was cupping Kate's breast in her hands, feeling the heat of her tits melting at her finger's touch.

"Ally, we can't," Kate moaned into her mouth while Ally pinched her nipples and pulled.

"No one will know," Ally said, wetly, into Kate's ear, letting her tongue sink across Kate's earlobe down to her cheek. "No one will know how badly you want to fuck your little sister."

Ally felt Kate's cock harden at her words, until her dick had grown to the point it rose above the hemline of her panties, pressing up just beneath her belly button.

"You don't even have to say it to me," Ally continued. "But I'll know." Ally lowered her hand to Kate's cock, finger barely hovering over Kate's tip. "But you're right," Ally said, pulling her hand away. "We can't."

"You're such a brat," Kate said, pulling Ally's sweater until their faces were close enough again to kiss. Kate was barely centimeters from Ally's face, their eyes could only see each other. "You said the house was making us this horny," Kate said, Ally breathing in her sister's breath with each word. The smell was minty and warm; Ally would drink it if she could. "But if we leave the house... what if we regret this? What if, when all of this is over, we wish we hadn't done it?"

"I would never in my life wish that," Ally said. "From right now, from this moment on, I think I'll always want you."

"Ally..."

"Kate."

That was the last word either of them needed to say. Their lips collided again, this time without resistance, only passion. Their hands traveled up each other's bodies, practically a mirror of each other. Kate's hand groped Ally's tit, and Ally's mouth opened in shock from the sensation; Kate's tongue danced across Ally's open mouth, replacing her spit with Kate's own, until their mouths shared one single, sensual flavor.

But it was their cocks Ally was focused on; she brushed her length against her sister's, ripping the panties from their waists until there was nothing between them but the heat of their own flesh, the gooey mix of their own pre-cum, and the need they felt for each other: Kate's hand wrapped around their lengths while Ally froze, pressed against her sister, their nipples gliding across each others while the cool air of the house kept their skin pricked and sensitive.

Then Kate's hand started to move, slowly at first, like she was uncertain of how to do this: the skin of their cocks rose over their tips and back down, then again. Each time, Ally thought she would explode at the sensation of their newly uncovered tips pressing against each other, the heat of her sister's dick throbbing against her own, the sight of their little slits kissing, just like their mouths were.

"I'm going to cum," Ally moaned against her sister's mouth.

"Oh, that's just like my baby sister, always wanting to finish first," Kate teased, increasing the pace of their frotting until Ally was certain she was going to burst or go insane. "Okay, Ally, you can cum for me." Kate pressed a kiss beneath her chin as she grinded her waist against Ally's forcing their cocks together, pressed up against Ally's stomach.

Ally blacked out, she was certain, as the sensation of the orgasm overwhelmed her: First her cum, shooting out in ropes of warm white seed, all across her stomach, pulsing against her sister, whose own cock in response to Ally's own, began throbbing as well: Then Ally was covered in the cum of two girls, the warmth of it seeping into her skin like magic, as she couldn't even moan, so totally was her mouth hidden beneath the mouth of her sister.

It took her almost a full minute to catch her breath. By the time she did, she realized she had fallen to the floor in a tangle of limbs with Kate, their legs looped together, their mouths no more than an inch apart.

"Do you still mean what you said?" Kate asked. "About still wanting me?"

"Forever," Ally said in a shaky breath, the pleasure of the orgasm still coursing through her.

"Then let's get cleaned up," Kate said. "And get to sleep. You'll have to stay here tonight after all."

Ally smiled, placing a wet kiss against her sister's lips. She thought of her grandfather's book. Of the trials of the house. As she felt tiredness overtake her, she was so, so glad that Kate was here with her. The house would be theirs, she had no doubt about it.
