“Prove your story”

“Prove it? That’s what you want me to do?” Taylor truly can’t believe your demand. “You sure you don’t want to, like, slap me around some more, shove your cock into my mouth and piss down my throat? Cause when I say I’ll do anything...”

“Prove it” you interrupt. Though to be honest Taylor’s offer sounds tempting.

“How am I supposed to prove it?” Taylor seems to be panicky, as if she knows the answer to her own question. “What do you to that party tonight?”

She thinks you know something about some party tonight. You don’t. You stay silent.

“I don’t know how you think we’d pull that off. You can’t pass as my brother.”

You get a sense of what she’s talking about. “It’s Halloween” you say “people wear masks”

Taylor breathes heavily. She’s nervous. “I think you’d rather slap me and...”

You slap her. Impossibly hard. She almost falls over.

“Maybe I’ll do both” you say grabbing your hard cock and holding it up to Taylor’s face. Her eyes focus in on it and then glaze over, entranced with lust. “Beg me.”

Taylor’s whole body quivers. “Please... um, what?”

“Beg me to go to that party”

Taylor’s closes her eyes and takes a deep breath. She knows she’s lost “Please. Please let’s go to the Sibling Sin Party”

You slap her again. “No!”

Taylor looks up at you with puzzles eyes. Her red lipstick is smeared from all the slapping. “Please let’s go. We have to go. It’s the most depraved party you’ve ever seen. You’ll love it.”

You pull your cock to the side and release it, slapping her across the face with your sweating manhood. “No”

“But...”

“I think instead I’m going to shove my cock in your mouth and piss down your throat.”

Taylor starts to part her lips almost instinctively. You hear her whisper to herself “dammit.” This girl who was being a real pain in your ass only moments ago has been tamed.

“Well?” You demand

“I don’t know” Taylor trips around her words. “Just do it all to me. Fucking take me.”

So you do. You push your member through her parted lips as deep as possible.

And Taylor is a pro. She doesn’t gag or resist at all. She takes it as deep as you want to push it. And when your nectar pours out down her throat she takes it all too.

“Do you like that, Sis?” You ask knowing she can’t answer but she closes her eyes and gives a nod.

When you’re done you pull your cock out slowly then crouch down so you and Taylor are face to face. “The depravity is just starting tonight, isn’t it.”

Again she nods.

You pull back your hand like you’re about to slap her. She doesn’t flinch. You don’t slap.

“We’re going to a new party aren’t we, Sis?”

“Yes, Bro”

End of Part One
