They had watched each other masturbate from across the room a few times. And after those initial bouts, it became a game.

“Who are you thinking about now?” Carly would ask her brother as he stroked his cock from the chair opposite where she played with her soaked folds.

He would throw out a girl’s name from school, maybe someone she’d met. “Betsy.”

“Betsy from the Drill team? Yeah kinda hot.Is she sucking your cock in your head?”

“Mmmm, yeah.”

“Think she’d eat my pussy after?”

“Fuck that’s hot!” and his strokes got more intense while her fingering deepened.

Now she was leading the witness.  “Any secret crushes you really wanna fuck? Like people you shouldn’t?”

He kept stroking, wondering if he dare tell his sister that he wanted her more than anyone. Instead he said, “Cousin Nancy?”

“Oooh, she has the longest yummiest legs and such perfect ass and tits. I’ve seen them. I’d fuck her too.” Carly said. He brother’s stroke quotient rose again,

Then he slowed and paused for a moment and took a deep breath. “And you” he said quietly.

“What?” She really wanted too hear him say it again.

“You. I wan to fuck you Carly” She moaned for him and shoved her fingers in deeper still. “Yessssss”, she hissed.

They stopped talking suddenly and locked eyes, They were both ramping up the self-play and clearly headed to newly intensified orgasms.

Carly broke the ice. “Are you gonna cum thinking of me right now?”

“Yes” he whimpered, nearing his peak.

“Then get over here cum on me while you tell me that you wanna fuck me.”

She flipped over on her belly and spread her legs wide while she lewdly took herself closer to her explosion.

She could feel him close to her and heard his shivered words repeated, “I wanna fuck you, Carly. I really wanna fuck you.”

That made Carly cum hard moaning, “Yes, God, Fuck meeee, Daveeeey!!!”

Suddenly Carly heard her brother gasp his telltale trigger sound, and soon stripes of cum streaked her warm skin from her perfect ass to her right shoulder, while one powerblast of cum just grazed her cheek and landed on the sofa’s back.

That actual connection of cum on skin took them across that next line of demarcation. Contact had been made and with the declaration of desire, brother and sister would be fucking in no time. For real.

To punctuate her own lust for the forbidden, Carly arched her head up and sensually licked the stray glob of cum from the sofa. She purred aloud, “Mmmmm, you taste sooo good, Davey.”

She turned around and sat up to see him standing weakly with his big fat sticky cock in his hand. “Next time, you might have to cum in my mouth.” She watched his eyes roll back at that suggestion.

And n the heat of the moment, she couldn’t help herself. She leaned in, grabbed his cock from his hand and said, “I cleaned off the sofa. Maybe I should clean you off now…”

And once she wrapped her lips around his dick, nothing would keep them from going all in on fucking, sucking and then some. She even made sure that he learned to eat his own cum from her pussy in a post-fucking face ride. 

“Every day, Davey. While you’re home, you have to fuck me every day now before you go back to college.”

“Yes, yes I will! I promise.” he said eagerly.

“Good. Make it even more often and you might earn the right to my ass cherry before you go back”

She had him hooked with that and she knew it. 

“Now tell me again how much you wanna fuck me every day, and what you’ll do to make sure I’m happy.”, she purred as she rocked on the underside of his reawakening tool.

“Tell me who you won’t fuck now that you have me. And then tell me who you’‘d bring in to share with me. One girl, one guy. I mean, you’d suck a cock for me to earn my ass cherry wouldn’t you?”

This was just the beginning of their trip down the kinky forbidden rabbit hole. She was going to milk this new game, and her all too willing brother, for everything that she could.
